Thermal management system for power battery based on pulsating heat pipe

Abstract

The invention discloses a thermal management system for a power battery based on a pulsating heat pipe, which comprises a module box and a module box top cover. The module box is internally equipped with at least two battery set monomer shells; each of the battery set monomer shells is internally provided with at least more than two battery module groups constructed by serially or parallelly connecting battery monomers; the surface of each battery monomer is provided with a pulsating heat pipe which is bent back and forth in the form of a row; the pulsating heat pipe is divided into an evaporation end and a condensation end; the evaporation end is attached on the surface of the battery monomer; and the condensation end is extended outside the surface of the condensation end. The thermal management system for a power battery based on a pulsating heat pipe provided by the invention has the advantages that the efficiency is high, the energy is saved, the environment is protected, the structure is simple, the cost is low, the operation is stable and reliable, and the function is diversified and etc.; furthermore, the high-efficiency thermal management comprising radiation, heating, working temperature control and waste heat recycling and the like of a power battery can be carried out without providing an external force or consuming the electric energy of additional batteries under a variety of charging and discharging conditions, the thermal management system is suitable for a variety of electrical equipments driven by a power battery, and the market prospect of the thermal management system is wide.

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 pulsating 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 hea...
