A kind of high-efficiency heat dissipation shock-absorbing energy-absorbing battery box

Abstract

The invention provides an anti-shock and energy-absorbing battery box with high heat dissipation, comprising: a battery box body, a scaly heat dissipation plate, a heat-conducting sandwich plate, and a battery module; the battery box body is welded by six sandwich panels, Each sandwich board is composed of two carbon fiber boards and an aluminum alloy sandwich; the battery box body is also provided with an air inlet and a suction fan; the heat-conducting sandwich board is distributed on the upper and lower sides of the battery module; the heat-conducting The sandwich plate is composed of two carbon fiber plates and a honeycomb sandwich; the heat-conducting sandwich plate is connected to the scaly heat sink by spot welding; the scale heat sink is equipped with multiple springs, and the springs are connected to the battery box body. The invention solves the problems that the current battery box cannot effectively dissipate heat and has no energy absorption and buffer structure, etc., and aims to improve the use performance and safety performance of the battery box, and realize the lightweight of the vehicle.

Description

technical field [0001] The invention relates to the technical field of battery packs for new energy vehicles, and more specifically, the invention relates to an anti-shock and energy-absorbing battery box with high heat dissipation. Background technique [0002] With the rapid development of society, new energy-saving and environmentally friendly new energy vehicles are favored by consumers. In recent years, electric vehicles have developed rapidly, and more and more electric vehicles have emerged, becoming a new and convenient means of transportation. Compared with automobiles, electric vehicles mainly rely on electric power to drive, which not only saves the cost of consumers to a certain extent, but also reduces exhaust emissions. However, an important factor restricting the development of electric vehicles is the battery box. At the same time of power, a large amount of heat will be generated. If the heat cannot be dissipated in time and effectively during driving, the e...
