Abstract

The invention discloses a vehicle-mounted inverter with convection heat dissipation and a heat dissipation and dust prevention method. The method includes a housing, an inverter circuit board mountedon the lower wall in the shell and heat dissipation openings formed in the two ends of the shell. When a device works, two fans directly facing the inversion circuit board can rapidly and efficientlydissipate heat of the inversion circuit board and the working heat can be discharged out of the device through the heat dissipation openings; through second ventilation holes formed in the top plate of the shell, air convection inside the shell can be accelerated, so that the device has better environment adaptability; the heat dissipation capacity of the device can be effectively improved throughtwo groups of convection heat removal systems, and the problem that the working efficiency and the service life of the device are influenced by excessive heat collection inside the device is solved.

Description

technical field [0001] The invention relates to the field of vehicle-mounted inverters, in particular to a vehicle-mounted inverter for convection heat dissipation and a method for heat dissipation and dust prevention. Background technique [0002] Car inverter The car inverter output through the cigarette lighter can be 20W, 40W, 80W, 120W until 150W power specification. Some higher power inverters need to be connected to the battery through connecting wires. Connect household electrical appliances to the output of the power converter and use various electrical appliances in the car as conveniently as at home. The electrical appliances that can be used include: mobile phones, notebook computers, digital cameras, cameras, lights, electric shavers, CD players, game consoles, handheld computers, electric tools, car refrigerators, and various travel, camping, and medical emergencies. [0003] However, in the prior art, the vehicle-mounted inverter still has a serious problem ...
