The embodiment of the utility model firstly provides a heat dissipation system of a mobile terminal, which can be a portable intelligent terminal known to a person skilled in the art, such as a notebook computer, a mobile phone, a tablet and other terminal equipment. The heat dissipation system provided by the embodiment is used for dissipating heat of the mobile terminals, so that the performance of the mobile terminals is better released, and the use safety is improved.
Referring to fig. 1, the heat dissipation system includes a support member 10, a liquid flow path 20, a cooling member 30, a storage member 40, and a power member 50.
The support 10 is used to support a mobile terminal, which may be placed on the support 10 during actual use. The support 10 is provided in a plate shape, the specific size and shape of which can be determined according to the mobile terminal to which it is adapted. In some embodiments, the support 10 may have a clamping function so that it can hold the mobile terminal by clamping, preventing the mobile terminal from sliding off the support 10 during use. In some embodiments, the support 10 may be provided with feet that may enable the support surface of the support 10 to be oriented in different directions or angles to adjust the mobile terminal to a suitable use position by a user. In some embodiments, the support 10 may be provided as a soaking plate so that it can better conduct heat of the mobile terminal.
The liquid flow channel 20 extends along the support member 10, and during actual use, coolant can flow in the liquid flow channel 20, thereby dissipating heat from the mobile terminal. The liquid flow channel 20 can extend along the surface of the support member 10, or the liquid flow channel 20 can also extend inside the support member 10, and a person skilled in the art can specifically set the position and the extending mode of the liquid flow channel 20 according to actual requirements, so that the coolant flowing in the liquid flow channel 20 can perform more sufficient heat exchange with the mobile terminal. The coolant herein may be water or other suitable liquid, without limitation.
And a cooling member 30, the cooling member 30 being spaced apart from the support member 10 and in fluid communication with the liquid flow path 20. The spaced arrangement here means that the cooling element 30 is not arranged directly on the support element 10, but at a distance from the support element 10. The cooling element 30 may be in fluid communication with the liquid flow channel 20 via suitable piping such that the coolant flowing out of the liquid flow channel 20 enters the cooling element 30, and the cooling element 30 may cool the coolant entering therein.
The cooling element 30 may cool the coolant by air cooling, for example, referring to fig. 2, in some embodiments, the cooling element 30 may include a fan 31 and a cooling cavity 32, the cooling cavity 32 is used to accommodate the coolant, and an air outlet of the fan 31 may be opposite to the cooling cavity 32, so that wind blown by the air outlet can cool the coolant in the cooling cavity 32. In some embodiments, the cooling member 30 may cool the coolant in other manners, which are not particularly limited.
In some embodiments, the cooling cavity 32 may be configured with a plurality of fin-shaped sub-cooling cavities to increase the heat exchange area of the coolant in the cooling cavity 32 for better cooling.
The storage element 40 is spaced from the support element 10 and the cooling element 30, and as such, the spacing herein means that the storage element 40 is spaced from both the support element 10 and the cooling element 30, and that the storage element 40 is in fluid communication with the cooling element 30 and the liquid flow path 20, which can be achieved by means of suitable piping, allowing the coolant flowing out of the cooling element 30 to enter the storage element 40 for storage, and allowing the coolant stored in the storage element 40 to enter the liquid flow path 20. The storage member 40 may be a device such as a water tank, or any other device having a coolant storage function, without limitation.
The power member 50 may drive the coolant to circulate among the storage member 40, the liquid flow passage 20, and the cooling member 30, that is, may drive the coolant to flow from the storage member 40 into the liquid flow passage 20, from the liquid flow passage 20 into the cooling member 30, and from the cooling member 30 into the storage member 40.
The power member 50 may be a device such as a circulation pump, and fluid communication between the storage member 40, the liquid flow passage 20 and the cooling member 30 may be achieved by a conduit as described above, and the power member 50 may be connected to any suitable location on the conduit. The power member 50 may be disposed at a distance from the storage member 40, the cooling member 30, and the support member 10, or the power member 50 may be disposed on the storage member 40 or the cooling member 30, without limitation.
It can be appreciated that in the actual heat dissipation process, the coolant exchanges heat with the mobile terminal, so that the temperature of the coolant flowing out of the liquid flow channel 20 is increased, while in this embodiment, the cooling member 30 is provided to cool the coolant flowing out of the liquid flow channel 20, and the cooled coolant reenters the liquid flow channel 20 via the storage member 40, so that the coolant entering the liquid flow channel 20 has a lower temperature all the time, thereby ensuring a better heat dissipation effect.
Further, no matter how the cooling element 30 is used to cool the coolant, a large amount of heat is generated during the operation, so that the cooling element 30, the storage element 40 and the support element 10 are further arranged at intervals, and therefore, the heat generated during the operation of the cooling element 30 is not transferred to the support element 10 or the storage element 40, and the heat exchange efficiency is prevented from being reduced due to the heat exchange with the coolant in the storage element 40 or the liquid flow channel 20.
On the other hand, if the cooling member 30 cools the coolant using air cooling, the provision of the cooling member 30 spaced from the supporting member 10 can further prevent the fan 31 of the cooling member 30 from directly blowing the mobile terminal, thereby preventing dust accumulation inside the mobile terminal.
In some embodiments, the heat dissipation system may further include one or more processors 60, which one or more processors 60 may be integrated into or coupled with any suitable component of the heat dissipation system, without limitation.
The one or more processors 60 can be electrically connected to the mobile terminal to enable data exchange with the mobile terminal to obtain operating parameters of the mobile terminal and to control the cooling efficiency of the cooling element 30 based on the operating parameters of the mobile terminal. The one or more processors 60 may implement electrical connection with the mobile terminal based on a device such as a data line or may implement electrical connection with the mobile terminal based on a near field communication device, a wireless communication device, etc., without limitation.
It can be appreciated that the working parameters of the mobile terminal can reflect the heat dissipation requirement of the mobile terminal to a certain extent, and the cooling efficiency of the cooling member 30 can be controlled based on the working parameters to maximally meet the heat dissipation requirement of the mobile terminal, so as to obtain a better heat dissipation effect, and meanwhile, under the condition that the heat dissipation requirement of the mobile terminal is lower, the cooling efficiency of the cooling member 30 can be correspondingly reduced, and the energy consumption is reduced. As described above, the cooling element 30 may cool the coolant by air cooling, and in such embodiments, the processor 60 may control the cooling efficiency of the cooling element 30, particularly by controlling the rotational speed of the fan 31.
In some embodiments, the above working parameters may specifically include parameters such as a memory occupancy rate of the mobile terminal, a processor working frequency, a processor temperature, a display card working frequency, a display card temperature, and a radiator working efficiency, where the radiator working efficiency refers to a radiator of the mobile terminal, such as a radiator fan of a notebook computer.
In some embodiments, the one or more processors 60 may also be configured to control the output power of the power member 50 to vary the flow rate of the coolant based on the operating parameters described above. In this embodiment, when the above working parameters indicate that the current heat dissipation requirement of the mobile terminal is high, the output power of the power component 50 may be increased to enable the coolant to flow faster, so as to increase the heat exchange efficiency between the coolant and the mobile terminal and ensure a better heat dissipation effect.
In some embodiments, referring to fig. 3, the heat dissipation system may further include a cooling member 70, and the cooling member 70 may be disposed within the storage member 40 to cool the coolant in the storage member 40. The cooling element 70 may be a semiconductor cooling device commonly used in the art, and in this embodiment, the cooling element 70 in the storage element 40 may be used to pre-cool and/or post-cool the coolant, so as to further ensure that the coolant entering the liquid flow channel 20 has a lower temperature, thereby ensuring a better heat dissipation efficiency.
In some embodiments, the one or more processors 60 may also control the opening and closing of the cooling member 30, the power member 50, and the cooling member 70 based on the operating parameters described above. That is, the processor may decide whether to turn on the device, and specifically which of the devices to turn on, based on the operating parameters to more reasonably balance heat dissipation efficiency and energy savings.
In some embodiments, the one or more processors 60 may turn on the refrigeration member 70 when the power member 50 and the cooling member 30 are in the off state, and turn off the refrigeration member 70 when the power member 50 and the cooling member 30 are in the on state.
It will be appreciated that a certain time is required for the cooling member 70 to cool the coolant, and when the power member 50 is turned on, the coolant is in a continuous flowing state, and the cooling member 30 may have a better cooling effect, but the cooling member 70 may not be capable of effectively cooling, resulting in energy waste. When the power unit 50 is closed, the coolant stops flowing, and the refrigerating unit 70 can have a better refrigerating effect. For this reason, in the present embodiment, the cooling member 70 is configured not to be turned on simultaneously with the power member 50 and the cooling member 30, and in actual use, if the mobile terminal temporarily does not need to dissipate heat by means of the heat dissipation system, the cooling member 70 may be turned on to cool the coolant, and the power member 50 and the cooling member 30 may be turned off. When the mobile terminal needs to dissipate heat, the power member 50 and the cooling member 30 can be turned on, and rapid heat dissipation can be achieved because the coolant in the storage member 40 has been cooled for a while and has a low temperature at this time. After the power member 50 and the cooling member 30 are turned on, the cooling member 70 may be turned off to save energy.
In some embodiments, still referring to fig. 1, the heat dissipation system further includes a first temperature sensor 81 disposed at an inlet of the liquid flow channel 20, and a second temperature sensor 82 disposed at an outlet of the liquid flow channel 20. The one or more processors 60 may also control the cooling efficiency of the cooling member 30 and/or the output power of the power member 50 based on the temperature difference obtained by the first temperature sensor 81 and the second temperature sensor 82.
In the present embodiment, the output power of the cooling member 30 and the power member 50 is controlled based on the temperature difference of the coolant flowing into and out of the liquid flow passage 20, and the temperature difference can more intuitively reflect the actual heat radiation effect than the operation parameter, and can exclude the interference of some external conditions during the actual use.
The two control methods described above, which are based on the operating parameters and based on the temperature difference, may be used separately or simultaneously to control the cooling member 30 and/or the power member 50, and may be selected by those skilled in the art according to actual needs without limitation.
In some embodiments, a plurality of ventilation holes 11 are provided on the support 10. As described above, some mobile terminals may be internally provided with a radiator such as a fan, and providing the plurality of ventilation holes 11 on the support member 10 can avoid blocking the radiating holes and the like provided in the mobile terminal itself, ensuring that the radiator provided in the mobile terminal itself can also have a good radiating effect.
In some embodiments, the liquid flow channel 20 may extend in a serpentine shape along the support 10. The serpentine extension can increase the heat exchange area of the coolant in the liquid flow channel 20 and the mobile terminal, so that the heat exchange efficiency is improved, and a better heat dissipation effect is obtained.
In some embodiments, the liquid flow channels 20 may be arranged in a relatively denser manner at the positions of the support 10 corresponding to the heat generating components of the mobile terminal, such as the positions corresponding to the components of the processor, the display card, etc., so that the coolant can exchange heat with the heat generating components with emphasis, and a better heat dissipation effect is obtained.
It will be appreciated that the above embodiments are exemplary and are not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
