Heat dissipation system of new energy automobile battery pack

Abstract

The invention discloses a heat dissipation system of a new energy automobile battery pack, and relates to the technical field of battery pack heat dissipation, the heat dissipation system comprises a battery box, a coiled pipe, a heat dissipation mechanism and a pressing mechanism, when the heat dissipation system is used, power is generated through a temperature difference power generation plate, the generated power is stored in an external energy storage power supply, and when the electric quantity in the energy storage power supply is sufficient, the heat dissipation mechanism is started; when the electric quantity in the energy storage power supply is insufficient, current is intermittently introduced into the spiral coil under the action of the control switch, so that a magnetic field is intermittently generated on the spiral coil, the magnetostrictive rod in the liquid storage tank intermittently extends or contracts, and the cooling liquid guides heat generated by the storage battery into the radiator and disperses the heat into external air; current is intermittently introduced into the spiral coil through the storage battery in the battery box, power generation of the thermoelectric power generation plate and the storage battery complement each other, current is continuously and intermittently introduced into the spiral coil, and the energy-saving and environment-friendly concept advocated at present is met.

Description

technical field [0001] The invention relates to the technical field of battery pack heat dissipation, in particular to a heat dissipation system for a new energy vehicle battery pack. Background technique [0002] Hybrid vehicles, pure electric vehicles and fuel cell vehicles are equipped with high-power battery packs inside. The battery pack is mainly used as the source of the main power or auxiliary power of the car. The battery pack will generate more heat when it is working. Cool the battery pack in time and quickly to avoid burning the battery pack. The existing battery pack consumes a lot of energy when cooling down, which is not in line with the concept of energy saving and environmental protection. Therefore, a cooling system for the battery pack of new energy vehicles is needed. Solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a heat dissipation system for a battery pack of a new energy vehicle, so as ...
