Problems solved by technology

However, the structure of the shell-and-tube heat sink is complex, and the actual engineering application cannot be easily modularized and expanded as required.
In addition, the system's heat dissipation pipes and filling design of phase change materials make the system too bulky and difficult to integrate with the limited space in the vehicle

Embodiment Construction

[0022] The hollow metal cold plate is used to improve the heat transfer effect between the battery pack and the phase change material, and the phase change material is filled in the metal cold plate shell, and the temperature of the battery pack is maintained in an appropriate working range through the heat absorption of the phase change material to ensure that the temperature of the battery is within the range. consistency between. And a coil radiator is arranged at the bottom of the hollow cold plate shell, and the liquid cooling working fluid is passed inside to take away the heat of the battery. Through the effective combination of the three cooling methods, the temperature of the battery pack can be significantly reduced to ensure the consistency of the temperature of the battery cells.

[0023] Such as figure 1 The schematic diagram of the heat dissipation and cooling device for the power battery is shown. The device includes two parts, one part is the power battery hea...

Abstract

The invention relates to a radiating and cooling device for a power battery. An aluminum hollow cold plate shell is in the form of a radiating fin; the inside of the shell is hollow; a plurality of groove spaces are formed on the aluminum shell; power batteries can be embedded into grooves; the aluminum hollow cold plate shell is filled with a phase change material; radiating fins are arranged on an aluminum hollow cold plate shell bottom plate; a snakelike copper tube is arranged at the bottom of an aluminum shell cavity, and is contacted with the phase change material; a liquid cooling working medium is introduced into the snakelike copper tube; the snakelike copper tube, a pump and an external heat exchanger are connected in series, so that an active liquid cooling system is formed; a temperature sensor is arranged on the surface of the power battery; and a temperature switch is connected in series with a pump body power supply. The flow of the cooling working medium can be adjusted according to different requirements of battery temperature control; the using amount of a metal is reduced by adding the phase change material on the premise of ensuring the battery radiating effect, so that the cost of a battery radiating device is reduced effectively; and the requirements of different power batteries are met.

Description

technical field [0001] The invention relates to a heat dissipation technology, in particular to a heat dissipation cooling device for a power battery. Background technique [0002] Energy and the environment have become the most concerned issues in the world. Energy is the foundation of the economy, while the environment is an important factor restricting economic development. How to solve the contradiction between economic development, energy supply and environmental pollution is the key to the sustainable development of a country and a nation. [0003] With the continuous increase in the number of cars, the deteriorating air quality caused by the emissions of many fuel vehicles and the gradual scarcity of oil resources are problems that human beings must face in the 21st century. The pressure of energy and the environment has brought unprecedented challenges to the development of traditional internal combustion engine vehicles. Governments, automobile companies, and scien...
