Abstract

An embodiment of the invention discloses a battery cooling device which comprises a battery pack (1), a plurality of layered flat heat pipes (5) and a cooling flow channel (13).The battery pack (1) comprises N battery modules (4), each battery module (4) comprises M single batteries which are parallelly arrayed, and the M and the N are natural numbers; each layered flat heat pipe (5) clings to spaces between the two corresponding single batteries (6); the cooling flow channel (13) transversely penetrates the multiple layered flat heat pipes (5); a cooling liquid inlet (7) is formed in one end of the cooling flow channel (13), a cooling liquid outlet (8) is formed in the other end of the cooling flow channel (13), and cooling liquid can flow into the flat heat pipes (5) through the cooling flow channel (13).The battery cooling device has the advantages that batteries can be quickly and stably cooled, and the high cooling efficiency and the cooling safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to a battery cooling device for a power battery pack of an electric vehicle. Background technique [0002] The current battery pack cooling solutions are mainly air cooling and liquid cooling. Although air cooling is a relatively economical and safe cooling method, it is passive cooling, and the cooling effect will change according to the environment. Therefore, this cooling method dissipates heat The efficiency is low, and the noise is loud, and the moving parts are easily damaged. [0003] Liquid cooling is to take away the heat generated by the battery by taking advantage of the large heat capacity of the liquid, but the whole system is more complicated, the cost is high, and it is difficult to maintain, and because the liquid is used as the heat transfer medium, the leakage problem involves the insulation and safety of the entire battery pack. . [0004] Phase change c...
