Battery pack heat pipe cooling system

Abstract

The invention provides a battery Pack heat pipe type cooling system. The system comprises a battery shell, a battery module and a heat pipe cooling system; the battery module is placed at the inner side of the battery shell, the heat pipe cooling system comprises a heat transfer plate, a heat pipe and a finned pipe, wherein the heat transfer plate is arranged on the battery module; one end of the heat pipe is arranged in the heat transfer plate, and the other end penetrates the battery shell; the finned pipe is arranged on the other end of the heat pipe and the outer side of the battery shell. Through the adoption of indirect cooling mode, the heat of the battery cell in the battery module is transferred to the heat pipe from the internal of the Pack, and the transferred to the finned pipe; through the adoption of the high conductivity of a gravity heat pipe, the high cooling capacity of the finned pipe and the irreversibility, the heat is finally dissipated in the air, and the cooling efficiency is high.

Description

technical field [0001] The invention relates to a battery thermal management system used in an automobile power battery or an energy storage battery, in particular to a battery pack heat pipe type cooling system. Background technique [0002] With the increasingly severe energy situation, the exhaust gas of automobiles and thermal power generation are also polluting our urban environment, and people are eager to improve the quality of urban living environment. At present, the Chinese government is vigorously promoting the development of electric vehicles, and the battery is the core component of the electric vehicle. However, the quality of the thermal management system of the battery directly affects the safety and reliability of the battery. [0003] The thermal management system includes a cooling system and a heating system, and the cooling system is a difficult problem that needs to be overcome urgently. If the battery temperature is too high without effective control, ...

AI Technical Summary

Problems solved by technology

Liquid cooling may cause liquid leakage and cause a short circuit. Special air tightness testing equipment is required, and there is a risk of air leakage in the later stage. In addition, external power is required for liquid circulation and cooling

Air cooling needs to filter the air into the inside of the Pack, which will reduce the IP protection level of the Pack, and the air filter needs to be replaced regularly, resulting in higher maintenance costs
