Abstract

A battery module with an air guide portion with two-channel air flow comprises a shell, a plurality of battery cells, a fan and the air guide portion; a containing space is defined by the shell, the battery cells are contained in the shell, the fan is contained in the shell and used for generating air flow to guide air into the shell from the outside, the air guide part is contained in the machine shell, the air guide part is arranged between the fan and the battery cells and guides the air flow to generate a non-uniform flow field, and the air flow of the non-uniform flow field provides more air flow for the high-temperature positions of the battery cells and provides less air flow for the low-temperature positions of the battery cells within a time interval.

Description

technical field [0001] The present invention relates to a battery module, in particular to a battery module with a dual-channel wind-flow air guiding part. Background technique [0002] At present, during the charging and discharging process of a general battery cell, the temperature of the battery cell body rises due to the electrons running in the filling material. When the temperature continues to rise and exceeds the temperature of the battery cell’s working range, the power supply efficiency of the battery cell itself is comparable to that of the battery. Life has a significant impact, so it is necessary to take away the generated heat energy to dissipate heat from the battery to keep the battery core running at its normal working temperature. The existing battery flow guiding structure is to provide a uniform fluid flow field to dissipate heat from the battery core. For example, U.S. Patent Publication No. US20180248239 discloses a heat dissipation structure, in which...
