Abstract

The invention discloses a power battery pack heat dissipation device with a heat pipe device. The power battery pack heat dissipation device comprises a housing, a separator plate, a heat dissipationheat pipe, an air cooling mechanism and a water cooling mechanism. The inner cavity of the housing is divided into a heat dissipation cavity and a heating cavity for holding a battery core through theseparator plate; the evaporation end of the heat dissipation heat pipe is tightly attached to the battery core located in the heating cavity; the cooling end of the heat dissipation heat pipe runs through the separator plate and then, stretches into the heat dissipation cavity; the air cooling mechanism is installed on the outer side of the housing, and a heat dissipation air duct of the air cooling mechanism communicates with the heat dissipation cavity; and the water cooling mechanism is connected with the cooling end of the heat dissipation heat pipe. Meanwhile, the invention further discloses a heat dissipation method of the power battery pack heat dissipation device with the heat pipe device. Moisture and dusts in air can be prevented from being attached to the surface of the battery, so that the battery is protected, and the performance of the battery is guaranteed; and meanwhile, different working modes can be adopted in the heat dissipation process, and the effects of energy conservation and emission reduction are achieved under the condition that the heat dissipation efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a heat dissipation device for a power battery pack with a heat pipe device and a heat dissipation method thereof. Background technique [0002] As one of the key components of electric vehicles, the power battery is responsible for energy storage and supply; the power battery will generate a lot of heat during charging and discharging, which will not only affect the life of the battery itself, but also affect the performance of the vehicle. And the safety of passengers brings hidden dangers; therefore, the heat dissipation problem of the power battery during use is one of the key contents of the electric vehicle technology research. [0003] The traditional way of forced air cooling of battery packs is to take away the heat generated by air flowing over the surface of the battery cells. In this heat dissipation mode, the air flow used for heat dissipation is in direct contact ...
