Abstract

The present invention discloses a new energy vehicle battery pack heat-dissipating device, pertaining to the technical field of new energy. The device comprises a box body. The left side and the rightside of the box body are uniformly provided with heat-dissipating fins. The bottom of the inner cavity of the box body is provided with a fan and a partition plate, and the partition plate is locatedabove the fan. The partition plate is uniformly provided with through holes. The output terminal of a temperature sensor is electrically connected with the input terminal of a microprocessor, the output terminal of the microprocessor is electrically connected with the input terminals of a display module, an alarm module and a driving module separately, and the output terminal of the driving module is electrically connected with the input terminals of a solenoid valve and the fan separately. The device has the advantage of high heat dissipation efficiency. The arrangement of the heat-dissipating fins can accelerate air circulation and realize fast cooling. The heat-dissipating fins and the box body are made by adopting high conductivity material, so that the heat conduction efficiency is improved. When the temperature of a battery pack is too high, the device can perform further heat dissipation by using the fan, so that the service life of the new energy vehicle battery pack is improved.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a heat dissipation device for a battery pack of a new energy vehicle. Background technique [0002] The energy storage of new energy vehicles (oil-electric hybrid vehicles and pure electric vehicles) requires the use of high-performance power batteries. During use, the internal temperature of the battery will rise due to high-current charging and discharging, making the battery temperature exceed its normal temperature. Use temperature, and even cause battery rupture, leakage, fire and explosion, thereby affecting the reliability and safety of the battery. The heat dissipation performance of the existing battery pack heat sink is poor, and the cost is too high, and the temperature monitoring of the battery pack cannot be well realized. Therefore, we propose a new energy vehicle battery pack heat sink. Contents of the invention [0003] The purpose of the present invention i...
