Specific embodiment
Embodiment:
Fig. 1 is please referred to, the present embodiment is semiconductor refrigerating constant temperature water tank comprising the water tank box being made by metal material1, several semiconductor chilling plates 2 being attached in 1 outer wall surface of water tank box, setting are surround in the fever of semiconductor chilling plate 2 oneThe first radiator structure 3 on side surface, is arranged in 1 inner wall of water tank box the cooling fan 4 being arranged on the first radiator structure 3The second radiator structure 5 on surface, the circulating pump 6 that interior circulation is stirred to the water in water tank box 1.
The heat absorbent surface of semiconductor chilling plate 2 is bonded with the outer surface of water tank box 1, carries out heat using water tank metal outer wallConduction, carries out refrigeration temperature control to the water in water tank.Semiconductor chilling plate 2 works as direct current using the Peltier effect of semiconductor materialWhen the galvanic couple that electricity is connected by two kinds of different semiconductor materials, heat can be absorbed respectively at the both ends of galvanic couple and releases heatThe purpose of refrigeration may be implemented in amount.Semiconductor chilling plate 2 realizes direct current input, convenient and solar power generation using DC12V power supplyDevice or energy storage battery, which are connected, to be used.
First radiator structure 3 include be bonded with 2 surface of semiconductor chilling plate be fitted and connected part 31, self-bonding interconnecting pieceDivide several radiated ribs 32 of outwardly extending and upper and lower spacer stack distribution.Cooling fan 4 is arranged on radiated rib 32, by forceChange the heat convection of air side, enhances refrigeration effect.
Second radiator structure 5 includes the radiated rib of several distributions of spacer stack up and down, increases the heat exchange area of water side,Improve refrigerating efficiency and refrigeration effect.
One end of circulating pump 6 is connected to by first pipe 61 with the bottom of water tank box 1, and the other end passes through second pipe 62It is connected to the top of water tank box 1, forms circulation loop, circulation is stirred to the water in water tank box 1, is increased in water tankHeat convection improves the temperature uniformity of the water in water tank.
Semiconductor chilling plate 2 forms a semiconductor refrigerating chip arrays, and the array and water in the outer surface of water tank box 1It is coated with heat-conducting silicone grease between 1 outer wall surface of box body, reduces heat transfer resistance, enhances heat transfer effect.
The present embodiment is applicable to vehicle-mounted use.
The present embodiment is that semiconductor refrigerating constant temperature water tank is freezed using semiconductor refrigerating chip arrays, and structure is simple, reliabilityIt is high；It is at low cost, it is easy to produce and process；Cold and hot two side liquid is all made of enhanced heat exchange measure, good refrigeration effect；Refrigerating operaton usesSmall wind machine array, noise are very low；DC supply input is easy to combine device of solar generating or energy storage battery, uses environmental protectionIt is energy saving, flexible and convenient.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, notUnder the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the inventionIt encloses.
