Abstract

The invention relates to a novel liquid cooling module with a multi-channel thin-wall straight pipe structure. The novel liquid cooling module comprises a battery cell bracket, wherein the battery cell bracket comprises an upper bracket plate and a lower bracket plate; the upper bracket plate and the lower bracket plate are symmetrically provided with a plurality of battery cell fixing grooves; abattery cell is fixedly arranged in each battery cell fixing groove; a liquid cooling module is sheathed under the connecting end of the upper bracket plate and each battery cell, and consists of a left harmonica vertical pipe, a right harmonica vertical pipe and a plurality of harmonica transverse pipes; the harmonica transverse pipes are welded between the left harmonica vertical pipe and the right harmonica vertical pipe; a plurality of triangular aluminum blocks are respectively welded at the two sides of each harmonica transverse pipe; the outer end surface of the left harmonica verticalpipe is provided with a liquid inlet, and the outer end surface of the right harmonica vertical pipe is provided with a liquid outlet. The novel liquid cooling module has the beneficial effects that by adopting the multi-channel straight pipe parallel type liquid cooling module, the structure is simple, the installation is convenient, the liquid cooling module can be well attached with the batterycell, and the temperature rise of the battery cell and the temperature difference between the battery cell can be effectively controlled; by designing the light-weight structure, the energy density of the module is high, and the pressure drop is little.

Description

technical field [0001] The invention relates to the technical field of thermal management of power batteries, in particular to a novel multi-channel thin-wall straight tube structure liquid cooling module. Background technique [0002] When the power battery is in use, it needs to be at a suitable temperature to ensure its normal use. At present, after the batteries are grouped, there are problems such as serious heating and uneven internal temperature distribution when charging and discharging at a high rate, which seriously affects the battery life. [0003] At present, most common thermal management methods adopt air cooling or liquid cooling. Air cooling is often difficult to solve problems such as temperature uniformity and regional promotion. Therefore, more liquid cooling methods are used in practical applications. Liquid cooling mainly takes away the heat generated by the battery cells by arranging a liquid cooling plate in the battery module, setting a flow channel...

Problems solved by technology

[0004] Due to the special circular structure of the cylindrical battery cell, the liquid cooling plate is often unable to effectively contact it, so as to export the heat generated by the battery cell, and often requires a sheet or tubular winding structure for heat conduction; at the same time, a silicone or metal heat conduction structure is used. , which will lead to many structural components and complex structure of the system; poor process operability; large temperature difference between battery cells
