A power management unit shell protection structure with dustproof function

Abstract

The utility model discloses a power management unit shell protection structure with dustproof function, including protection shell, the upper surface of protection shell is inlayed with heat abstractor, the upper surface of protection shell is connected with filter mechanism, the right side of protection shell is connected with conveying mechanism. The device passes through the design of coarse filter screen, medium filter screen and high -efficient filter screen, and dust and suspended particle are filtered in multiple stages, ensure that the airflow after filtering reaches the dustless state, lay the foundation for the subsequent protection element into the protection shell inside, utilize the design of fan, straw and shell, and the shell generates negative pressure suction force, and the clean airflow after multistage filtration is sucked into the straw inside, through the intercommunication of connecting pipe and protection shell, and the clean airflow is conveniently and stably conveyed to the inside of protection shell, utilize the design of heat dissipation fan, cylinder and activated carbon board, and the hot airflow in the inside of protection shell is conveniently discharged, and the purpose of heat dissipation and dust prevention is completed.
