Embodiment Construction

[0031] The preferred embodiments of the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0032] 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 loop heat pipe 3 without additional power, so as to efficiently manage the heat of the battery. The system includes a module lower box 4, a module upper box 6, and a partition plate 2 in the module box. At least two battery cell shells 8 are placed in the module lower box 4, and each battery cell shell Inside the body 8 are placed at least two battery module groups composed of battery cells 1 connected in series or in parallel, and flat plate loop heat pipes 3 are distributed on the surface of each battery cell 1 . Such as Figure 5 As shown, the flat plate loop heat pipe 3 is divided into an evaporation section 10, a condensation section 9, a g...

Abstract

The invention discloses a power battery thermal management system based on flat loop heat pipes. The system is characterized in that: it includes a module upper box, a module lower box and a middle partition board. The middle partition board is arranged between the module upper box and the module lower box, the module lower box is internally provided with at least two battery pack monomer shells, at least over two battery module groups composed of battery monomers connected in series or in parallel are placed in each battery pack monomer shell, wherein each battery monomer is provided with a flat loop heat pipe on the surface, the flat loop heat pipe falls into an evaporation section, a liquid storage chamber, a gas line, a liquid line and a condensation section, the evaporation section is disposed on the battery monomer surface, the condensation section is located in the module upper box, and the liquid storage chamber is arranged over the battery monomer in the module lower box. With the characteristics of large heat dissipating capacity, high heat dissipating efficiency, and simple processing, the power battery thermal management system provided in the invention can efficiently solve the technical problems of high-temperature heat dissipation, low temperature heating thermal preservation and heat recycling in power batteries.

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 flat plate loop heat pipe. Background technique [0002] Countries around the world are paying more and more attention to issues such as energy crisis and environmental pollution, and correspondingly deepening awareness of energy conservation, emission reduction and environmental protection. Electric vehicles such as electric vehicles and hybrid vehicles relying on power batteries will inevitably become the trend of clean energy development. Compared with other electric equipment, electric vehicles have no pollutant emissions and are more economical than fuel vehicles. They are valued by many research institutions, electric vehicle manufacturers and battery manufacturers. The power of electric vehicles is provided by the power battery, which converts chemical energy into electrical energy through internal complex che...
