Heat exchanger for cooling battery
The present invention relates to the technical field of batteries of new energy vehicle, and in particular to a heat exchanger for cooling battery. The present invention aims to solve the problem that existing heat exchangers in the prior art have low heat exchange efficiency and lack of expandability. For this purpose, the heat exchanger for cooling battery according to the present invention comprises a first liquid collection unit, a second liquid collection unit and at least one cooling plate unit provided between the first liquid collection unit and the second liquid collection unit, the first liquid collection unit at least comprising a first liquid collection area, the second liquid collection unit at least comprising a second liquid collection area, and the cooling plate unit comprising a plurality of flow guide elements. Through a modular design, the present invention can make combinations and changes according to variation of size of a battery pack, bring about great degree of freedom in size, reduce cost and shorten production cycle. In addition, a coolant flows in all directions under the action of the flow guide elements, which is advantageous for a uniform distribution of speed in the cooling plate unit and a more uniform distribution of temperature over the entire region of the cooling plate unit. Meanwhile, heat conducting elements play the role of enhancing heat exchange, which is advantageous for an improvement of heat exchange efficiency of the cooling plate.
