Abstract

The invention discloses a power battery liquid-cooling apparatus. The liquid-cooling apparatus comprises a plurality of cooling apparatuses, wherein inlets of the cooling apparatuses are conducted; outlets of the cooling apparatuses are conducted; each cooling apparatus comprises a plurality of cooling plates; inlets of the cooling plates are conducted; outlets of the cooling plates are conducted; and a battery module or a battery cell is mounted on each cooling plate. According to the power battery liquid-cooling apparatus provided by the invention, all the cooling plates are arranged in parallel, so that a cold medium can enter each cooling plate by flow distribution to cool the battery module or the battery cell, and then the cold medium exits from the outlet of each cooling plate, gathers together and exits from the outlet of each corresponding cooling apparatus. Compared with the prior art that cooling apparatuses are arranged in series and a cold medium conveyed by a pipeline generates heat accumulation in a pipeline conveying process to cause low heat dissipation efficiency, the liquid-cooling apparatus has the advantages that due to the adoption of a parallel cooling mode, the heat accumulation of the cooling medium caused by an excessively long flow channel is reduced and the heat dissipation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power battery liquid cooling device. Background technique [0002] At present, the new energy vehicle power battery liquid cooling device is a horizontal cooling structure, that is, the battery modules or cells are arranged horizontally on the bottom surface of the power battery box or bracket, between the bottom surface of the power battery box or the bottom surface of the power battery box and the module A cooling device arranged in series through pipe connection is provided to meet the heat dissipation requirements of battery modules or cells arranged horizontally. And because the cooling devices are arranged in series, the refrigerant transported by the pipeline will generate heat accumulation during the pipeline transportation process, resulting in low heat dissipation efficiency. [0003] Therefore, how to improve the heat dissipation efficiency of the power battery ...
