Cooling device of storage battery of electric vehicle

Abstract

The invention relates to the field of storage batteries, in particular to a cooling device of a storage battery of an electric vehicle. The cooling device comprises an inner housing equipped with a storage battery body as well as an outer housing, wherein a heat conducting copper plate is laid on the inner surface of the inner housing; a temperature sensor and a central processing unit are arranged on the inner surface of the heat conducting copper plate; an S-shaped wound heat conducting copper tube is uniformly laid on the outer wall of the inner housing, space outside the heat conducting copper tube is filled with heat conducting filler; the heat conducting copper tube is filled with a coolant; two ends of the heat conducting copper tube are communicated with a water inlet and a water outlet of a low-temperature coolant circulating pump respectively; the central processing unit are electrically connected with the temperature sensor and the low-temperature coolant circulating pump. Cooling is performed layer by layer through the heat conducting copper plate, the inner housing, the heat conducting copper tube, the heat conducting filler, the outer housing and cooling fins from inside to outside, auxiliary cooling can be performed at a high temperature by means of the external low-temperature coolant circulating pump, an irreplaceable cooling effect is realized, and the cooling device is more energy-saving and more environment-friendly by means of matched control of the temperature sensor and the central processing unit.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to a cooling device for an electric vehicle accumulator. Background technique [0002] At present, electric vehicles on the market all have cooling devices, but the heat dissipation is not ideal when running. At the same time, electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. Due to strong demand, China's electric vehicle market has maintained leapfrog growth in recent years. However, when the temperature is too high, the battery of the tram sometimes spontaneously ignites, causing damage to the property of the user. [0003] Therefore, we are badly in need of designing a heat sink for an electric vehicle storage battery t...
