Embodiment Construction

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0037] As the power source of electric vehicles, the power battery is generally composed of multiple battery modules stacked in series in the battery pack of the power battery. Multiple battery modules are concentrated and fixed in a battery pack for power supply. During actual use, due to the fact that the battery power supply process will generate a certain amount of heat, if the heat accumulates in a certain area of ​​the battery pack for a long time, it will cause the batteries near this area to The module is in a state of deep discharge, which not only causes the charging state of the battery module to deviate from other batteries, but eventually leads to the damage of the entire battery component, and eventuall...

Abstract

The invention relates to the technical field of new energy vehicles, in particular to a battery heat dissipation device special for a new energy vehicle. The battery heat dissipation device special for the new energy vehicle comprises a battery pack heat exchange mechanism, a radiator and a heat exchange liquid circulation assembly, wherein the battery pack heat exchange mechanism comprises a main heat exchange shell formed by assembling an upper shell and a lower shell, a first cavity used for heat exchange of a battery pack is formed in an inner cavity of the upper shell, and a second cavity used for letting in cooling liquid is formed in an inner cavity of the lower shell. A partition plate used for partitioning the upper shell and the lower shell and a supporting piece used for bearing the battery pack are sequentially arranged in an inner cavity of the main heat exchange shell from bottom to top. The device has the beneficial effects that an immersion type heat exchange mode is adopted, the heat exchange efficiency is better, heat generated during operation of the battery pack can be rapidly guided out so as to avoid long-time accumulation of the heat in the battery, the risk of causing a fire disaster is reduced, and the whole battery is safer in the practical process.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a special battery cooling device for new energy vehicles. Background technique [0002] The composition of new energy electric vehicles includes: electric drive and control systems, mechanical systems such as drive force transmission, and working devices to complete established tasks. The electric drive and control system is the core of electric vehicles, and it is also the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of a drive motor, a power supply, and a speed control device for the motor. [0003] With the rapid development of modern society, people's living standards and life pursuits are getting higher and higher. As a convenient means of transportation, cars have entered thousands of households, making the number of cars in my country grow rapidly. The development of the automobile industry has pro...
