[accompanying drawing explanation]
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic diagram of embodiment of the present invention automobile air conditioning system electric cabinet heat radiation cooling device.
Fig. 2 is the structural representation of embodiment of the present invention automobile air conditioning system electric cabinet heat radiation cooling device.
[embodiment]
The structure of embodiment of the present invention automobile air conditioning system electric cabinet heat radiation cooling device as depicted in figs. 1 and 2, comprises the casing 10 of electric cabinet, the circuit board 8 be arranged in casing 10, coil heat exchanger 6 and adsorptive pads 9.Casing 10 is airtight casings, and coil heat exchanger 6 is connected in the refrigeration pipe of automobile air conditioning system.
As shown in Figure 2, circuit board 8 and other circuit components are arranged in the top of coil heat exchanger 6, and adsorptive pads is arranged in the below of coil heat exchanger 6.
Circuit board 8 keeps a determining deviation by support and heat exchanger 6.The heat that the refrigerant suction electric elements flow through in heat exchanger 5 come out, becomes superheated steam, thus ensures that the temperature in electric cabinet can not raise.Beneath pad one deck absorbent material of heat exchanger 6, can prevent the condensed water in face outside heat exchanger 6 from producing potential safety hazard because body oscillating splashes on electric elements.
As shown in Figure 1, automobile air conditioning system comprises compressor 1, four-way change-over valve 2, condenser 3, expansion valve 4, evaporator 5 and gas-liquid separator 7, the first interface D of four-way change-over valve 2 connects the outlet of automobile air conditioning system air conditioner, and the second interface C of four-way change-over valve 2 is connected the 3rd interface E of four-way change-over valve 2 successively by condenser 3, expansion valve 4 and evaporator 5; 4th interface S of four-way change-over valve 2 connects the entrance of coil heat exchanger 6, and the outlet of coil heat exchanger 6 connects the entrance of automobile air conditioning system compressor 1 by gas-liquid separator 7; In cooling mode, the first interface D of four-way change-over valve 2 is communicated with the second interface C automobile air conditioning system, and the 3rd interface E is communicated with the 4th interface S; In a heating mode, the first interface D of four-way change-over valve 2 is communicated with the 3rd interface E, and the second interface C is communicated with the 4th interface S.
