The invention discloses a cold plate of a battery pack, a heat exchange system, the battery pack and a vehicle. The cold plate comprises a shunting area, a first flow channel and a second flow channel. The shunting area is used for shunting the inflowing heat exchange fluid; the first flow channel and the second flow channel are used for heat exchange of different areas of the battery pack; and the first flow channel and the second flow channel are respectively communicated with the shunting area. The shunting area is provided with a flow adjusting piece; when the temperature of the heat exchange fluid is located in a first temperature interval, the flow adjusting piece is used for adjusting the flow flowing into the first runner area to be larger than the flow flowing into the second runner area; when the temperature of the heat exchange fluid is in the second temperature interval, the flow adjusting piece is used for adjusting the flow flowing into the first runner area to be smaller than the flow flowing into the second runner area. The flow flowing into the first flow channel area and the second flow channel area can be adjusted according to different temperatures of heat exchange fluid input into the cold plate during refrigeration or heating, and the function of adjusting flow distribution of different branches according to refrigeration or heating requirements is achieved.
本发明公开了一种电池包的冷板、换热系统、电池包和车辆,该冷板包括分流区、第一流道和第二流道。分流区用于对流入的热交换流体进行分流;所述第一流道和第二流道用于对电池组不同区域换热;第一流道和所述第二流道分别与分流区连通。分流区设置流量调节件;热交换流体的温度位于第一温度区间时,流量调节件用于调节流入第一流道区的流量大于流入第二流道区的流量;热交换流体的温度位于第二温度区间时,流量调节件用于调节流入第一流道区的流量小于流入第二流道区的流量。能够根据制冷或制热时输入冷板的热交换流体的温度的不同,调整流入第一流道区和第二流道区的流量,具备根据制冷或制热需求,调整不同支路流量分配的功能。
