Temperature difference driven cooling device for on-board energy storage system

Abstract

The invention relates to a differential-temperature-driven vehicular energy storage system cooling device comprising a box, cooling air passages, a differential temperature generation source, a power management unit, a compressed air generator and an air amplifier. Power is generated by temperature difference between an energy storage system unit chamber and the environment thereof as well as an energy storage unit and the environment thereof, the compressed air generator is driven by the power, compressed air is guided and amplified so as to obtain large-flow cooling air through the air amplifier, and the cooling air flows through the energy storage system to achieve cooling. The differential-temperature-driven vehicular energy storage system cooling device is simple, easy to use, safe, and low in cost; through differential temperature drive, the vehicle energy consumption is not increased, and cruising power is improved while effective cooling is guaranteed; through the air amplifier, the defect that air energy is low in density is overcome and the cooling effect is better; the larger the cooling load is, the larger the temperature difference is, the higher the differential temperature driving force is and the higher the cooling power is, so that a self-feedback system is formed; the differential-temperature-driven vehicular energy storage system cooling device is applicable to electric vehicles and hybrid vehicles.

Description

technical field [0001] The invention relates to a cooling device for a vehicle-mounted energy storage system, in particular to a temperature-difference-driven air amplification cooling device for the vehicle-mounted energy storage system, and belongs to the technical field of cooling. Background technique [0002] In recent years, vehicles such as hybrid electric vehicles and pure electric vehicles have been put into use more and more, all of which need to be equipped with energy storage systems with sufficient capacity, which also brings problems in the layout and cooling of energy storage systems. At present, the structure of the energy storage system is huge, and it is mainly arranged in the car and on both sides of the car body or on the roof. The former is limited by the car body structure and cannot meet the needs of customers for fully utilizing the car interior space and different forms of car body structures; the energy storage system is arranged in The roof is the ...
