Liquid cooling heat dissipation structure battery module

Abstract

The utility model discloses a kind of liquid cooling heat dissipation structure battery module, comprising: battery pack, battery pack includes first radiating cold plate and a plurality of blade battery plate and second radiating cold plate, first radiating cold plate is provided with liquid inlet main flow channel and liquid outlet main flow channel in, every second radiating cold plate is provided with liquid flow channel in, liquid inlet of liquid flow channel is connected with the first connecting hole above liquid inlet main flow channel and is connected and communicated, liquid outlet is connected with the second connecting hole above liquid outlet main flow channel and is connected and communicated.Using the above technical scheme, when injecting coolant into liquid inlet main flow channel, coolant passes through first connecting hole, liquid inlet enters liquid flow channel, and absorbs heat on second radiating cold plate, and then coolant is output from the liquid outlet of liquid flow channel, passes through second connecting hole and enters liquid outlet main flow channel and is discharged, so as to realize the cooling of battery pack, and the cooling effect can be achieved by liquid cooling mode, the probability of battery module can be reduced, and the service life of battery module can be improved.
