[0026] In the above technical solution, the heat exchange device 2 is connected in series on the circulating water circuit of the battery pack, so that the circulating water temperature of the battery pack is reduced.
[0027] When the battery pack temperature is too high, the vehicle host controls the first electromagnetic valve 15 to close, and controls the second electromagnetic valve 16 to open at the same time, at this time, the low-temperature refrigerant output from the evaporator passes through the heat exchange device 2, and the circulating water of the battery pack also passes through the heat exchange device 2, and the circulating water is cooled by the refrigerant.
[0028] This cooling method is added on the basis of the original water circulation of the battery pack, and is only used when the cooling capacity of the battery pack itself is insufficient.
[0029] Referring to Figure 2 , the refrigerant enters from A and flows out from B, and the battery pack cooling water flows in from C and flows out from D.
[0030] Referring to Figure 2 , the heat exchange device 2 includes a shell 21 and a shell cover 22, the inside of the shell 21 is welded and fixed with a closing plate 23, the inside of the closing plate 23 forms a through cavity 24 for refrigerant, the other end of the closing plate 23 is welded with heat exchange fins 25, the heat exchange fins 25 are covered by the shell cover 22, a water inlet pipe 26 is welded at one end face of the shell cover 22, and a water outlet pipe 27 is welded at the other end face of the shell cover 22, and a pipe joint 28 connecting the first branch pipe 13 and the second branch pipe 14 is arranged outside the shell 21.
[0031] In the above technical solution, the refrigerant flows into the through cavity 24 through the first branch pipe 13, and then flows out through the second branch pipe 14, so that the heat exchange fins 25 are cooled, and the circulating water of the battery pack passes through the side of the closing plate 23 away from the through cavity 24, and contacts the heat exchange fins 25 when passing through, so that the temperature of the circulating water is reduced, which is beneficial to the cooling of the battery pack.
[0032] Referring to Figure 3 , a bolt 221 is connected between the shell 21 and the shell cover 22.
[0033] A sealing ring 222 is arranged between the shell 21 and the shell cover 22, and the sealing ring 222 is located inside the bolt 221.
[0034] The shell 21 and the shell cover 22 are combined to form a glue groove 223, and the glue groove 223 is located outside the bolt 221.
[0035] In the above technical solution, the inside is sealed by the sealing ring 222, and the outside sealing property is increased by the glue groove 223.
[0036] Preferably, a mounting pipe 141 is arranged outside the second branch pipe 14, a temperature sensor 151 is mounted through the mounting pipe 141, and the temperature sensor 151 is connected to the automobile host.
[0037] In the above technical solution, the temperature sensor 151 detects the temperature of the refrigerant flowing out of the heat exchange device 2, and when the temperature sensor 151 detects that the outflow temperature of the refrigerant is greater than 20 degrees Celsius, the first electromagnetic valve 15 is opened and the second electromagnetic valve 16 is closed by the vehicle host, so that the refrigerant does not pass through the heat exchange device 2, but directly passes through the pipe body 1.
[0038] Avoids that the temperature of the refrigerant entering the compressor is too high.
[0039] Until the next battery pack high temperature, re-enable.
[0040] If the battery pack continues to be high temperature, the heat exchange device is started by the vehicle host at intervals to minimize damage to the compressor.
