Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the system transfers the heat generated by the battery cells to the external environment of the battery module through the flat heat pipe 1, so as to efficiently manage the heat of the battery. The system includes a module box 4 and a box top cover 3 . A cooling water circulation cavity is provided at the bottom of the box body 4 and inside the top cover 3 , and communicates with the flat heat pipe 1 . The cooling water enters the bottom of the box from the water inlet 6, flows through the flat heat pipe 1, takes away the heat and enters the top cover 3 of the box, and finally discharges from the water outlet 7. At least two battery cell casings 8 are placed in the module box 4, and at least two battery module groups composed of battery cells 2 connected in series or in ...

Abstract

The invention discloses a power battery heat management system based on flat plate heat pipes. The power battery heat management system comprises a module box body and a module box body top cover, wherein at least two individual battery group shells are placed in the module box body; at least two battery module groups formed by connecting individual batteries in series or in parallel are placed in each individual battery group shell; a flat plate heat pipe with a cooling system is arranged on the surface of each individual battery and is attached to the surface of the corresponding individual battery; cooling water circulates in the flat plate heat pipes. The power battery heat management system has the advantages of high efficiency, simple structure, stable and reliable operation, functional diversity and the like, is used for performing efficient heat management, including heat dissipation, heating, waste heat recycling and the like, on a power battery under various charge-discharge conditions, is applicable to various types of electric equipment driven by power batteries, and has wide market prospect.

Description

technical field [0001] The invention relates to a thermal management system of a power battery, in particular to a thermal management system of a power battery based on a flat 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 o...
