Problems solved by technology

When used as an electric vehicle battery, multiple batteries need to be used in parallel or in series. The batteries are stacked together and placed in the box. The heat dissipation in the battery box is not good, which will cause damage to the batteries and make the batteries useless. Reduced lifespan, increased cost

Abstract

The invention provides an air-cooling structure, comprising a cover body and at least a built-in heat dissipation channel; wherein, an air inlet port of the heat dissipation channel is arranged on theside wall of the cover body, an air outlet port of the heat dissipation channel is arranged on the bottom wall of the cover body, and the position of the air outlet port corresponds to the position of the battery module in the battery box. According to the air-cooled structure, the heat dissipation channel is arranged in the housing, such that a sandwich structure is formed between the battery module and the heat dissipation channel, so as to improve the heat dissipation effect of the battery module, In addition, when the external cold air enters the heat dissipation channel from the air inlet port, it meets the hot air (heat) generated by the battery module. If condensed water is generated, the condensed water can be discharged through the cover body, thus avoiding insulation problems caused by the battery module, thereby improving the safety and reliability of the battery module, and further prolonging the service life of the battery module.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an air-cooled structure, in particular to an air-cooled structure and a battery box. Background technique [0002] New energy has now become a hot topic in all walks of life. New energy vehicles (electric vehicles) and energy storage are one of the most important members of new energy, and the development trend is gratifying. The development of new energy provides new opportunities for electric vehicles to provide power sources, automobile batteries and energy storage batteries. [0003] Lithium batteries are widely used due to their high energy density, low pollution, high cycle life, no memory effect, and fast charging. Lithium batteries are used in new energy vehicles. When used as an electric vehicle battery, multiple batteries need to be used in parallel or in series. The batteries are stacked together and placed in the box. The heat dissipation in the battery box is not go...
