The invention discloses a heat dissipation device for a battery pack of a new energy vehicle. The device comprises a base; a cooling liquid tank is fixedly connected to the bottom of a side wall of the base; a buffer frame is fixedly connected to a top plate of the cooling liquid tank in an equal-angle mode; a supporting block is fixedly connected to the top of the axis of the base; and a supporting top plate is fixedly connected to the top of the supporting block. The invention relates to the technical field of new energy vehicles. According to the heat dissipation device for the battery packof the new energy vehicle, the battery pack is clamped; a certain buffer damping function is realized; meanwhile, a cooling plate is used for fixing and wrapping the battery pack; a circulating pumpenables a cooling liquid to perform rapid cooling on the battery pack through a cooling pipe; heat of batteries is taken away by the cooling liquid, and a loop is formed; the effect of rapid cooling is achieved; the cooling is rapid; the use is safe and convenient; the outer wall of the battery pack is subjected to air cooling; the ratio of the number of air inlet fans to the number of exhaust fans is 2:1; the air cooling circulation effect is formed; and the performance and the service life of the battery pack are improved and prolonged.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a cooling device for battery packs of new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Vehicles with new technology and new structure, new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, other new energy vehicles, etc. Pure electric vehicles are a kind of vehicles that use a single battery as The car with energy storage power source, which uses the battery as the energy storage power source, provides electric energy to the motor through the battery, drives the motor to run, ...
