Heat exchange plate with self-heating function

Abstract

The invention discloses a heat exchange plate with a self-heating function, which is applied to a lithium battery module. The heat exchange plate comprises a metal main body and a surface heating sheet, wherein the metal main body is provided with a flow channel with uniformly-arranged interior, and the exterior is provided with a water inlet and a water outlet. According to the heat exchange plate with the self-heating function, the heating sheet is a thin-shaped surface heating body and has good thermal conductivity, soft surface quality and high insulation property, and can be compounded ona surface of the metal main body, and meanwhile a heat-conducting silica gel sheet is pasted on the other surface of the metal main body, so that the heat exchange efficiency is increased; and afterthe above process is completed, the whole device is uniformly pressed at a pole lug, wherein the calorific value of a battery module is large, and finally a bidirectional function of heating and cooling batteries can be realized on the premise that the heat exchange plate is used as a base material.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a heat exchange plate with self-heating, in particular to a heat exchange plate structure of a novel lithium-ion pouch battery. Background technique [0002] Lithium-ion power batteries have been widely used in new energy pure electric vehicles and hybrid new energy vehicles. At present, during the use of users, it is inevitable that they will encounter severe cold weather, and even work for a long time under extremely cold temperature conditions. The activity of positive and negative ions has a great influence. Therefore, in the process of using the battery in the actual environment, how to quickly and effectively raise the temperature of the battery to a temperature level that can work normally has always been a key issue in our technical research. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provi...
