The present invention is achieved by following technical solution.
A kind of anti-interference air-cooled controller structure, including shell, fan, heating device, high voltage power circuit board, filter
And low-voltage control circuit plate, the enclosure interior are provided with air duct, the high voltage power circuit board and low-voltage control circuit plate point
It is not placed on air duct upper and lower surface, the fan, which is mounted on shell, leans on cold wind import one end, and the filtering device is mounted on wind
Close to cold wind exit end above road, the heating device is arranged in above air duct.
It is additionally provided with air duct cover board in the air duct.
The heating device pastes air duct cold plate along the inlet and outlet direction of cold wind according to the size of power consumption, pacifies from front to back
Dress.
The housing bottom is fixed with lower cover by screw.
The case top is fixed with upper cover plate by screw.
Power supply base and signal control socket are respectively arranged on the upper cover plate.
The heating device is power tube.
The beneficial effects of the invention are as follows：
Compared with prior art, the present invention sets air duct and realizes that multi-panel heat dissipation and power circuit, control circuit are isolated in utilizing
Dual function radiates for controller power device, coordinates doubling plate function, forms motor circuit and weak electric signal circuit institute
Two totally-enclosed cavity body structure reduction systems in influence of the forceful electric power to weak electric signal.Air-cooled channel is placed on complete machine simultaneously
The centre of structure, cold plate and the integral heat sink structural integrity of controller design, and the heat dissipation of complete machine single side is made to become centered on air duct
Four sides is radiated, and effective improving heat radiation efficiency, high voltage power circuit and control circuit are separately mounted to upper and lower surface, will using shell
Forceful electric power area and light current area form independent sealed space, play strong and weak electricity buffer action, reduce internal system forceful electric power and light current
It interferes with each other.
