Problems solved by technology
[0003] Electric vehicles are usually equipped with a battery pack and a motor cooling fan. The main heat dissipation surface of the battery pack is located at the bottom of the battery pack, and the air outlet end of the motor cooling fan is relatively close to the bottom of the battery pack. Sweep the bottom of the battery pack, which will cause the battery pack to overheat, affect the heat dissipation of the battery pack, and reduce the service life of the battery pack

The invention relates to the technical field of heat insulation, and discloses a heat insulation shell and a moving body. A flow guide cavity is formed in the heat insulation shell, the flow guide cavity includes a first side cavity wall facing the heat source, and the flow guide cavity includes a front cavity for being arranged relatively on both sides of the first side cavity wall in the advancing direction of the moving body The front cavity wall is formed with a front diversion port, and the rear cavity wall is formed with a rear diversion port. In actual use, the heat insulation shell is arranged between the heat source of the mobile body and the heat-resistant parts, and the hot air discharged from the heat source will be blown on the outer surface of the first side cavity wall, while the diversion cavity can further slow down or prevent heat transfer To prevent the heated parts, when the moving body moves, a flowing airflow is generated between the front diversion port, the diversion chamber and the rear diversion port. Local heat concentration, the heat insulation shell can block the hot air discharged from the heat source from directly blowing the heat-resistant parts, and can have a good conduction and heat insulation effect during the moving process of the mobile body.
Description
technical field [0001] The invention relates to the technical field of heat insulation, in particular to a heat insulation shell and a moving body. Background technique [0002] At present, with the development of environmental protection and technology, electric vehicles are becoming more and more popular. [0003] Electric vehicles are usually equipped with a battery pack and a motor cooling fan. The main heat dissipation surface of the battery pack is located at the bottom of the battery pack, and the air outlet end of the motor cooling fan is relatively close to the bottom of the battery pack. Sweep the bottom of the battery pack, which will cause the battery pack to overheat, affect the heat dissipation of the battery pack, and reduce the service life of the battery pack. [0004] For this reason, in the prior art, the battery pack housing adopts a double-layer aluminum plate structure, and a cooling method combining natural convection cooling and water cooling is adop...
