The embodiment of the application discloses a heat dissipation device of energy storage equipment.
Referring to fig. 1 to 9 together, in an embodiment of the present application, a heat dissipating device for an energy storage device includes a battery mounting frame 100, where the battery mounting frame 100 is made of a material with better heat conductivity, such as copper, aluminum, steel, etc., and the preferred embodiment is made of aluminum with a low density of about 2.7g/cm3, and can significantly reduce the weight compared to other materials such as steel (about 7.83g/cm 3). And the heat conduction capacity of the aluminum material is about 5 times that of steel, and the good heat conduction can rapidly conduct heat generated in the battery during the charge and discharge process. Meanwhile, compared with some high-performance metal materials such as copper, titanium and the like, the aluminum material has lower cost, and the good processing performance of the aluminum material is also beneficial to reducing the processing cost, so that the manufacturing cost of the battery can be reduced and the production benefit can be improved while the performance and the safety of the battery are ensured.
Referring to fig. 1 to 9 together, in an embodiment of the present application, a plurality of battery mounting cavities 101 and heat dissipation cavities 102 are formed inside a battery mounting frame 100, a storage battery 103 is mounted inside the battery mounting cavities 101, a heat dissipation tube 104 is mounted inside the heat dissipation cavities 102, an input box 105 and an output box 106 for containing heat dissipation medium are respectively disposed at two ends of the outer end of the battery mounting frame 100 corresponding to the heat dissipation tube 104, and a circulating heat dissipation assembly 400 is disposed between the input box 105 and the output box 106.
In the course of the work, can make the heat dissipation medium circulate the heat dissipation operation between input box 105 and output box 106 through circulation heat dissipation subassembly 400 and cooling tube 104, the even densely covered design in battery installation cavity 101 and cooling cavity 102 can be efficient with the heat that the battery inside produced in the charge-discharge process in through battery mounting bracket 100 conduction to cooling tube 104, and then guaranteed the radiating effect to the large capacity battery.
Referring to fig. 1 to 9, in an embodiment of the present application, the heat dissipation medium may be configured as different liquid media according to different application environment conditions, for example, liquid water, glycol-water mixed solution, silicone oil, gallium-based liquid metal, etc.
Water is a common and efficient liquid heat sink medium. It has higher specific heat capacity (4.2×103J/(kg, seed)), and uses water as heat-dissipating medium, when the battery heats, the water can absorb heat, thus effectively reducing the battery temperature. And the water has low cost, is easy to obtain and is environment-friendly.
The glycol-water mixed liquid is an antifreezing cooling liquid widely used. The freezing point and boiling point of the mixed solution can be changed by adjusting the proportion of the glycol and the water so as to adapt to different temperature environments. For example, in a large-sized energy storage battery system in a cold region, using a glycol-water mixture (e.g., a glycol content of 40% -60%) as a heat dissipation medium, the freezing point thereof can be reduced to-20 ℃ or even lower, effectively preventing the cooling liquid from freezing at low temperature. Meanwhile, the high specific heat capacity characteristic of water is inherited, and the heat generated by the battery can be well absorbed.
The silicone oils are used in a wide range of temperatures, typically between-40 ℃ and 200 ℃. In some battery cooling systems in high temperature environments, such as industrial high temperature storage batteries or large Uninterruptible Power Supply (UPS) systems in hot areas, silicone oil can effectively absorb and transfer heat as a cooling medium. Meanwhile, the oil medium is not conductive, and safety problems such as battery short circuit and the like can not be caused by leakage.
The thermal conductivity of gallium-based liquid metals is several orders of magnitude higher than that of water. In some battery systems with extremely high heat dissipation requirements, such as power batteries of high-performance electric vehicles or energy storage batteries with high power density, the liquid metal can rapidly conduct out the heat generated by the batteries. And the liquid metal is in a liquid state at normal temperature or in a certain temperature range, so that the battery can be well adapted to the shape and the heat dissipation channel of the battery.
Referring to fig. 1 to 9 together, in an embodiment of the present application, each radiating pipe 104 is internally provided with a valve assembly 200 and a temperature driving assembly 300, the valve assembly 200 is in transmission connection with the temperature driving assembly 300, and an automatic control assembly 500 electrically connected with the circulating radiating assembly 400 is further provided between the input box 105 and the output box 106.
In the working process, the valve assembly 200 can be driven to be opened and closed by utilizing the temperature driving assembly 300 according to the temperature change of the periphery of the radiating pipe 104, and the circulating radiating assembly 400 can be automatically controlled to be started and stopped by utilizing the automatic control assembly 500.
When the valve assembly 200 is opened, the automatic control assembly 500 automatically controls the circulation radiator assembly 400 to start, and the circulation radiator assembly 400 circulates the radiator medium inside the input tank 105 and the output tank 106. When all the valve assemblies 200 are closed, the automatic control assembly 500 automatically controls the circulation radiator assembly 400 to stop, and after the circulation radiator assembly 400 stops, the radiator media inside the input tank 105 and the output tank 106 are in a stationary state. Therefore, the heat dissipation medium can conduct accurate heat dissipation according to the heating condition of each storage battery 103, the uniformity of heat dissipation of the energy storage equipment can be guaranteed, and the energy consumption required during heat dissipation operation can be reduced.
Referring to fig. 1 to 9 together, in an embodiment of the application, the valve assembly 200 includes a valve sleeve 201, a first external thread 202 is provided on an outer side surface of the valve sleeve 201, a first internal thread 203 is provided inside the radiating pipe 104 corresponding to the first external thread 202, the valve sleeve 201 is hermetically and threadedly connected inside the radiating pipe 104 through the first external thread 202 and the first internal thread 203, a smooth cylindrical surface 204 is provided on an inner side surface of the valve sleeve 201, a piston valve 205 is hermetically and slidingly connected inside the valve sleeve 201, and the piston valve 205 is in transmission connection with the temperature driving assembly 300.
During operation, the piston valve 205 can be driven to move using the temperature drive assembly 300. When the piston valve 205 moves from the inside of the cylindrical surface 204 to the outside of the valve sleeve 201, the corresponding valve assembly 200 is in an open state, and the heat dissipation medium in the input box 105 can enter the output box 106 through the corresponding heat dissipation pipe 104, so that the pressure in the input box 105 and the pressure in the output box 106 are equal, and at the moment, the heat dissipation working state can be achieved after the automatic control assembly 500 is used for automatically controlling the circulating heat dissipation assembly 400 to be started.
Meanwhile, the relative positions of the valve sleeve 201 and the piston valve 205 can be adjusted through the sealing threaded connection of the first external thread 202 and the first internal thread 203. When the external environment temperature of the application of the energy storage device is low, such as northern europe, siberia, northeast China and the like, or in winter, the heat generated by the storage battery in the working process is relatively easier to dissipate. Because the low temperature environment forms a large temperature gradient with the temperature of the storage battery, heat is naturally conducted from the high temperature storage battery to the low temperature external environment. In this way, the valve sleeve 201 can be adjusted to a position farther from the temperature driving assembly 300 through the first external thread 202 and the first internal thread 203, so that the moving distance of the temperature driving assembly 300 for driving the piston valve 205 to open the valve assembly 200 can be increased, which is beneficial to further reducing the energy consumption required by heat dissipation and increasing the energy saving performance of the energy storage device.
Similarly, when the external environment temperature of the energy storage device is higher, the valve sleeve 201 is adjusted to a position closer to the temperature driving assembly 300 by the first external thread 202 and the first internal thread 203, and the moving distance of the temperature driving assembly 300 for driving the piston valve 205 to open the valve assembly 200 is reduced, so that the heat dissipation performance of the storage battery is guaranteed. The design can ensure that the energy storage equipment can be used in complex and severe environments, and the practicability of the heat radiating device is further improved.
Referring to fig. 1 to 9 together, in an embodiment of the application, a first spring 206 is fixedly connected to an end of the piston valve 205 away from the temperature driving assembly 300, a choke frame 207 is rotatably connected to an end of the first spring 206 away from the piston valve 205, a fourth external thread 208 is provided at an outer end of the choke frame 207, and the choke frame 207 is screwed with the first internal thread 203 and the radiating pipe 104 through the fourth external thread 208.

In the working process, when the temperature of one storage battery 103 rises, the battery mounting frame 100 can timely transfer heat to the radiating pipe 104 close to the outer side of the corresponding storage battery 103, and because the radiating medium is in a static state when the valve assembly 200 is closed, the radiating medium in the radiating pipe 104 can rapidly transfer heat to the thermosensitive medium through the piston cylinder 301, the thermosensitive medium can be expanded after being heated by utilizing the characteristic of thermal expansion and contraction, the piston body 302 in the piston cylinder 301 is pushed to move, and the piston body 302 drives the valve assembly 200 through the piston rod 303, so that the corresponding valve assembly 200 is controlled to be opened, and the radiating medium can perform circulating heat dissipation.
In a specific embodiment of the application, mercury is adopted as a common liquid metal, the thermal expansion coefficient is high, the piston is obviously expanded to generate displacement due to small temperature change, the volume is linearly changed along with the temperature, the temperature is favorably and accurately reflected, meanwhile, the thermal sensitive medium is stable in chemical property, good in compatibility with common materials, good in fluidity, and capable of stably pressing to sensitively and stably move the piston of the piston body 302, and the thermal sensitive medium is high in boiling point, low in solidifying point and wide in applicable temperature range, can stably work in various environments, and is beneficial to effectively converting temperature change into mechanical movement.

During operation, when the cooling medium is in a static state, heat generated by the battery is transferred to the heat-sensitive medium through the battery mounting frame 100, the radiating pipe 104, the cooling medium and the piston cylinder 301 in sequence, and the heat-sensitive medium drives the piston valve 205 to slide through the piston body 302 and the piston rod 303 after being heated and expanded. When the piston valve 205 is slid to open the valve assembly 200, the cooling medium is circulated from the input tank 105 into the output tank 106 through the valve assembly 200 and the radiating pipe 104.
In the operation process of circulating cooling of the cooling medium, the flow velocity of the cooling medium flowing through the gap between the flow guide cover 304 and the radiating pipe 104 can be accelerated by the flow guide cover 304, and heat can be taken away rapidly by the accelerated flow velocity of the cooling medium, because more cooling medium flows through the radiating pipe 104 in unit time, the efficiency of heat transfer can be improved. Thereby reducing the accumulation of heat within the battery mount 100 and reducing the risk of localized overheating.

Referring to fig. 1 to 9, in an embodiment of the present application, a plurality of second heat dissipation fins 113 are uniformly and densely distributed on a side of the output box cover 108 away from the output box 106, an outer housing 114 is fixedly mounted on the battery mounting frame 100, air inlets 115 are symmetrically disposed on a side surface of the outer housing 114 near the upper side of the outer housing, corresponding to the second heat dissipation fins 113, an inclined surface 116 is disposed on a position of the second heat dissipation fins 113 near the air inlets 115, an air outlet 117 is disposed on a bottom of the outer housing 114 corresponding to the fan 407, and a panel 118 is detachably and hermetically mounted on the outer housing 114.
In the working process, as shown by an arrow in fig. 3, after the fan 407 is started, external air can be pumped into the outer shell 114 from the air inlet 115 and then discharged from the air outlet 117 through the second cooling fin 113 and the circulating cooling assembly 400, in this process, the fan 407 not only can directly cool the circulating cooling assembly 400, but also can utilize the second cooling fin 113 to carry out auxiliary cooling on the output box 106 and cooling mediums in the output box. In addition, since the air inlet 115 is formed on the side surface of the outer casing 114, when the fan 407 is not started, natural wind can be used to dissipate heat of the second heat sink 113, so that the heat dissipation effect is further improved.
Referring to fig. 1 to 9 together, in an embodiment of the present application, an automatic control assembly 500 includes a first connecting pipe 501 and a second connecting pipe 502, the first connecting pipe 501 is fixedly and hermetically connected to an input box 105, the second connecting pipe 502 is fixedly and hermetically connected to an output box 106, a pressure pipe 503 is fixedly and hermetically connected between the first connecting pipe 501 and the second connecting pipe 502, a sliding column 504 is hermetically and slidingly connected to an inner portion of the pressure pipe 503, a sliding groove 505 is formed on a side wall of the pressure pipe 503, a push plate 506 slidingly limited inside the sliding groove 505 is fixedly connected to the sliding column 504, a box 507 is fixedly connected to an outer portion of the pressure pipe 503, a control switch 508 electrically connected to a circulation heat dissipation assembly 400 is arranged inside the box 507, the control switch 508 is electrically connected to a delivery pump 404 and a fan 407, and the control switch 508 is abutted to the push plate 506. The end of the push plate 506 away from the control switch 508 is fixedly connected with a second spring 509, and the end of the second spring 509 away from the push plate 506 is fixedly connected to the box body 507.
During operation, the pressure tube 503 is utilized to directly monitor the pressure changes inside the input tank 105 and the output tank 106.
When all the valve assemblies 200 are closed, the circulating heat dissipation assembly 400 continues to input heat dissipation medium into the input box 105, the pressure in the input box 105 is increased, the heat dissipation medium pushes the sliding column 504 to slide towards a direction away from the control switch 508 through the first connecting pipe 501, and when the sliding column 504 drives the push plate 506 to leave the control switch 508, the control switch 508 automatically controls the circulating heat dissipation assembly 400 to stop.
When any one of the valve assemblies 200 is opened, the pressure in the input box 105 stops acting on the sliding column 504, the second spring 509 reversely pushes the sliding column 504 to slide in a direction approaching the control switch 508, and when the sliding column 504 drives the push plate 506 to abut against the control switch 508 again, the control switch 508 automatically controls the circulation heat dissipation assembly 400 to be opened.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
