Problems solved by technology

Its main disadvantages are: when the air duct enters and exits the battery pack, the waterproof and dustproof level is insufficient due to the material and matching method of the air duct; the cross-sectional area of ​​the air duct is large, and it takes up a lot of space; It is difficult to design the internal air duct of the battery pack; the fan evaporator assembly is arranged outside the battery pack, the cooling energy transmission path is long, the cooling energy loss is large, and the temperature consistency of the battery inside the battery pack is poor; the system structure is complex and the components are many, resulting in high cost

Abstract

The invention relates to a battery cooling and heating device for an electric automobile. The battery cooling and heating device consists of an upper shell, an evaporator, a fan A, a fan bracket, a fan B, a lower shell and a heater, wherein the evaporator, the fan A, the fan bracket, the fan B and the heater are sequentially arranged inside the upper shell and the lower shell; when the fan of the fan A rotates, air enters the fan A from a heating direction and is blown to the evaporator; when the fan of the fan B rotates, the air enters the fan B from an evaporator direction and is blown to the heater direction. The battery cooling and heating device has the characteristics of compact structure, fan arrangement in forward and reverse directions, excellent vibration attenuation and centralized cooling and heating integration.

Description

Technical field [0001] The invention belongs to the field of electric vehicles, and specifically refers to a battery cooling and heating device for electric vehicles. Background technique [0002] As one of the core components of electric vehicles, the battery faces the shortcomings of high temperature discharge such as life attenuation and thermal instability. Therefore, the battery temperature control interval directly determines the safety performance, service life and driving range of the battery. Therefore, it is particularly important to develop a safe, efficient, and uniform power battery pack cooling and heating device. [0003] The current heating methods in the cooling and heating device of the battery pack mainly include the following methods: heating plate, silica gel belt heating, PTC heater heating, water cooling plate heating, etc. Among them, the heating plate is heated by contact heat conduction, but because it directly acts on the battery cells, there are many in...
