A large-scale battery module integrated box cooling system based on heat pipes

Abstract

The invention discloses a large-scale battery module integrated box cooling system based on heat pipe, includes a battery module, cooling box and heat pipe, the battery module integrated cabinet includes an integrated cabinet housing with a top opening, The cooling box comprises a cooling box shell with a top opening, a plurality of groups of cooling plates and a spraying device, wherein the cooling plates are fixedly connected with the cooling box shell, the spraying device is fixed in the cooling box shell, and the spraying device is correspondingly provided with a plurality of groups of cooling plates; A heat pipe mount bracket fixed on that integrate box shell and the cooling box shell has one end arranged between battery modules arrange in parallel and the other end arranged on the cooling plate. The invention improves the assembling efficiency of the battery module, greatly reduces the battery temperature, improves the battery consistency in the battery module and the stability when outputting, and prolongs the battery service life.

Description

technical field [0001] The invention relates to a battery cooling device, in particular to a large-scale battery module integrated box cooling system based on heat pipes. Background technique [0002] As a component of the energy storage device, the battery is a key component of the energy storage system. It generates a large amount of heat during charging and discharging, which causes the thermal runaway phenomenon of the single battery inside the battery module, which makes each single battery and each battery module There is a very serious unbalanced temperature distribution between them, which causes a performance mismatch between the batteries, which further leads to premature failure of the battery module. [0003] At present, most large-scale battery module integrated box systems use air-conditioning systems for cooling to achieve the purpose of reducing battery temperature and balancing the temperature between batteries. However, the operating cost of air-conditionin...

[0002] As a component of the energy storage device, the battery is a key component of the energy storage system. It generates a large amount of heat during charging and discharging, which causes the thermal runaway phenomenon of the single battery inside the battery module, which makes each single battery and each battery module A very serious unbalanced temperature distribution is generated between the cells, resulting in a performance mismatch between the cells, which further leads to premature failure of the battery module

[0003] At present, most large-scale battery module integrated box systems use air-conditioning systems for cooling to achieve the purpose of reducing battery temperature and balancing the temperature between batteries. However, the operating cost of air-conditioning system cooling is relatively high, which is not conducive to the development of large-scale energy storage systems. to promote
