Problems solved by technology

However, in this scheme, the serpentine cooling flat tube has a narrow internal flow channel and a long flow path, and the cooling medium suffers from large resistance along the way, which makes the cooling effect worse.
At the same time, there is also a hidden danger of liquid leakage in this cooling method.
In addition, this arrangement is more complicated and the overall cost is higher

Abstract

The invention relates to a thermal conducting structure and an extensible liquid cooling power battery module and belongs to the field of automobile batteries. The thermal conducting structure comprises a thermal conducting plate and two liquid cooling plates, wherein the thermal conducting plate is composed of two side plates and a plurality of thermal conducting sheets, both ends of every thermal conducting sheet are fixedly connected with the two side plate, and every thermal conducting sheet is provided with a plurality of grooves matched with cylindrical battery cells; the two liquid cooling plates are arranged on both sides of the thermal conducting plate and attached to the side plates, and cooling water channels are formed inside the liquid cooling plates and extend in the length direction of the thermal conducting sheets. The thermal conducting structure is simple in structure and low in cost, and when matched with the cylindrical battery cells, can transfer heat generated bythe cylindrical battery cells to the side plates on both sides and dissipate the heat via the liquid cooling plates connected with the side plate. The extensible liquid cooling power battery module comprises a battery cell module with the thermal conducting structure, thereby improving the heat dissipating efficiency of the battery cells, ensuring the temperature consistency of the battery cells,improving the energy density and reducing the production costs.

Description

technical field [0001] The invention relates to the technical field of automobile batteries, in particular to a heat conducting structure and an expandable liquid-cooled power battery module. Background technique [0002] With the increasingly serious problems of energy shortage and environmental pollution, the automobile industry is facing great pressure on energy conservation and emission reduction. Electric vehicles have good development prospects due to their environmental protection advantages. Major car manufacturers have also launched their own pure electric and hybrid vehicles. [0003] The battery is the core component of electric vehicles, and it is also a huge problem that limits its development. The electrochemical performance of the battery is closely related to its temperature. Too cold or too hot will reduce the service life and efficiency of the battery, so strict thermal management is required. [0004] At present, for cylindrical batteries, the liquid cool...
