Problems solved by technology

The heat dissipation device can transfer the heat of multiple single batteries to a certain extent and dissipate heat quickly. However, the overall temperature of the battery module is still relatively high, and the problem of heat dissipation has not been completely solved. Therefore, it is urgent to make improvements to the existing technology. to meet their actual needs

Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0027] Such as Figure 2~4 As shown, in this embodiment, the battery module of the present invention includes: a battery array 1 , a heat sink 2 , a cooling pipe 3 and a casing 4 . The battery array 1 includes several single batteries. In this embodiment, the batteries are cylindrical batteries, and several batteries are arranged in a staggered arrangement in the battery array 1 . Of course, the batteries are not limited to cylindrical batteries, and the arrangement of the batteries in the battery array is not limited to the staggered arrangement. For example, in other embodiments, the batteries can also be curved batteries, and the batteries are aligned in the battery array.

[0028] The cooling fins 2 are interspersed in the battery array 1 , and the cooling pipes 3 are arranged on both sides of ...

Abstract

The invention discloses a battery module and a cooling method thereof. The battery module comprises a battery array mainly formed by a plurality of single batteries, cooling fins inserted into the battery array, and cooling pipes into which a refrigerant is introduced, wherein the cooling pipes are arranged at the two sides of the battery array, and the cooling fins are circuitously inserted into the battery array and penetrate out of the battery array to be fixedly arranged on the cooling pipes. According to the scheme, the cooling fins are circuitously inserted into the battery array, so that the contact areas of the cooling fins and batteries can be increased, the heat conduction is fully carried out, and heat is transferred to the cooling pipes to exchange heat with the refrigerant, and thus the cooling of the battery array is realized, and the cooling effect is good.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery module and a cooling method thereof. Background technique [0002] Batteries are widely used in daily life and production activities, and are also known as one of the indispensable consumer goods in modern society. The battery module is assembled by connecting several battery modules. When using the battery module, each single battery module will generate heat. If it is used for a long time, the heat of several battery modules will accumulate. The heat dissipation and cooling of the battery module will have an impact on the performance, service life and safety of the battery. Traditional battery modules often use natural heat dissipation for cooling, but the effect of this method is not good. In the prior art, there is still water cooling or forced air cooling to cool the whole module. Since the heat of the battery module mainly comes from the single battery module,...
