Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] like figure 1 As shown, the system transfers the heat generated by the battery cells to the external environment of the battery module through the loop heat pipe 3 without additional power, so as to efficiently manage the heat of the battery. The system includes a module box 1 and a top cover of the box. At least two battery cell casings 2 are placed in the module box 1, and at least two battery cells are placed in each battery cell casing 2. A battery module group composed of cells connected in series or in parallel, and a loop heat pipe 3 is distributed on the surface of each battery cell. like image 3 As shown, the loop heat pipe 3 is divided into an evaporating end 4 and a condensing end 5, the evaporating end 4 is attached to the surface of the battery cell, and the condensing end 5 protrude...

Abstract

The invention discloses a power battery thermal management system based on loop heat pipes. The power battery thermal management system includes a module box, in which at least two battery pack monomer shells are placed. At least over two battery module sets composed of battery monomers connected in series or in parallel are placed in each battery pack monomer shell, wherein loop heat pipes are distributed on the surface of each battery monomer. Each loop heat pipe comprises an evaporation end and a condensation end. The evaporation end fits the battery monomer surface, and the condensation end extends beyond the battery monomer surface. With the characteristics of large heat dissipation capacity, high heat dissipation efficiency and simple processing, the power battery thermal management system can efficiently solve the technical problems of high-temperature heat dissipation, low temperature heating and heat preservation, as well as heat recycling of power batteries, and is suitable for various electrical equipment dependent on power batteries to drive, thus having broad market prospects.

Description

technical field [0001] The invention relates to a power battery thermal management system, in particular to a power battery thermal management system based on a loop heat pipe. Background technique [0002] With the increasingly prominent problems of energy crisis and environmental pollution, as well as the deepening awareness of energy conservation, emission reduction and environmental protection in various countries around the world, electric equipment such as electric vehicles and hybrid vehicles driven by power batteries will inevitably become the trend of clean energy development. Especially electric vehicles, which are powered by power batteries, have no pollutant emissions, and are more economical than fuel vehicles, have attracted widespread attention worldwide. Due to the complex internal chemical reactions of the power battery during the charging and discharging process, especially during the large-size and high-current discharge process, a large amount of heat is ...
