From the heat radiator body direction move, and make the second penetrator ram drive wind collection 830 near the electromagnet direction or
Person moves away from the direction of the heat radiator body, so, it is possible to make the screening dirt portion be misplaced with the air intake of the heat dissipation channel
Set, and the second end of the ventilation duct is connected with the exhaust vent, and then make the second end of the ventilation duct logical with described
Wind area is connected, and so, extraneous air can just be circulated in the heat dissipation channel, to play convection heat transfer' heat-transfer by convection effect, and
Because the two ends of the wind collection are in communication with the outside, i.e., the two ends of described plenum area are in communication with the outside respectively, and block
Part, relative to the heat dissipation channel, although the two ends of the heat dissipation channel are all in communication with the outside, but the air intake of heat dissipation channel
End can be by the inhibition of mounting blocks, and the heat dissipation channel can be subject to the inhibition of the side wall of the wind collection, therefore, institute
Stating the air velocity of plenum area can be more than the air velocity of the heat dissipation channel, according to aerodynamics, can improve the radiating
The air velocity of passage, even if the air of the heat dissipation channel post flows to the plenum area, so, it is possible to improve to spreading
The degree of heat, and then overall heat dispersion can be improved.
