The equal hollow out in top and bottom, automatically controlled device installation room west be equipped with into tracheae, this enter tracheae bending and opening direction direction
The bottom surface hollow out position of sub-assembly positive direction, automatically controlled device installation room is covered with filter grid；From fan screen front
View directions, the aperture position for entering tracheae are located in the range of flabellum edge.
Preferably, the hollow out position that installing pipe encloses on the top cover is covered with latticed plastic cover plate, the modeling
Material cover board enters automatically controlled device installation room for accommodating sundries.
Preferably, being equipped with power knob at the plastic cover plate.
Preferably, the base side has for the installation otic placode that fan screen installation is fixed.
Preferably, the front filter screen is detachably arranged on the shell of front；Back side filter screen
It is detachably arranged in back housing.
Using the beneficial effects of the utility model are:
This fan screen is made by the way that installing pipe is arranged inside top cover, automatically controlled device installation room, filter grid, enters tracheae
It obtains in fan rotation, the front of fan screen forms air pressure negative pressuren zone, and air enters fan screen from the front of fan screen
Interior, and then successively by entering tracheae, automatically controlled device installation room and installing pipe, final air is from installing pipe top opening location stream
Out, so that the electric control gear air blast cooling heat dissipation of automatically controlled device installation room, the service life of electric control gear and reliable is greatly prolonged
Degree.
