Description

technical field [0001] The invention relates to the technical field of electromagnetic refrigeration, in particular to a battery thermal management device. Background technique [0002] With the increasing demand for new energy vehicles, safety accidents such as spontaneous combustion and explosion of electric vehicles are also becoming more and more frequent. The spontaneous combustion and explosion of electric vehicles, the reason is that in addition to the battery itself, the battery thermal management system that controls the battery temperature also plays a key role. At present, the battery thermal management systems on the market are mainly air cooling and liquid cooling. Traditional air cooling is the simplest and most convenient method, but its cooling surface has a small heat transfer coefficient and low heat transfer efficiency, making it difficult to meet the requirements of rapid heat dissipation. However, the pipeline layout of the liquid cooling method is com...
