Detailed Description

Referring to fig. 1, 2, 3, 4, 5 and 6, the present embodiment is for a motor intake louver. The utility model comprises a groove plate 2, a sponge pad 1, a mesh plate 5, an angle plate 3 and a clapboard 4. The groove plates 2 are strip-shaped grooves, the cross section of each groove plate is in a shape of ']', the upper part, the lower part, the left part and the right part of each groove plate are respectively provided with one groove, the notches are inwards connected with the frames at the air inlets of the motors to form a frame-shaped structure, and the grooves are filled with sponge liners 1; the sponge pad 1 enables the contact surface of the air inlet of the motor and the groove plate 2 to have elasticity and adsorbability, vibration noise of the groove plate 2 and the motor is reduced, and wind noise passing through a gap at the joint of the groove plate 2 and the motor is also blocked. A screen plate 5 is welded on the outer side of the groove plate 2, and the screen plate 5 is of a plate-shaped net structure; the screen 5 is of a net structure and is used for blocking foreign matters brought in by inlet and outlet air. The angle plate 3 is a strip plate with an L-shaped cross section, is connected to the side of the groove plate 2 and covers the outer side of the groove plate 2, so that a frame-shaped structure is formed by the side and the outer side of the groove plate 2; the angle plate 3 covers the groove plate 2, the sponge pad 1 and the screen plate 5, and plays a role in integral protection. The partition plates 4 are arc-shaped plate-shaped and are obliquely arranged between the net plate 5 and the angle plate 3 at equal intervals. The partition plate 4 includes a slant plate portion 4-1 and a curved plate portion 4-2; the inclined plate part 4-1 is connected with the net plate 5, and the curved plate part 4-2 is connected with the angle plate 3; the inclined plate part 4-1 is inclined upwards, and the included angle between the inclined plate part and the screen plate 5 is 115-135 degrees; the curved plate part 4-2 is of a curved arc type. The utility model discloses the inside negative pressure fan work of cooperation motor, under negative pressure fan's negative pressure effect, cold air gets into from flexion 4-2, because the flow direction of cold air is from low to high, and the design upwards adapts to wind path change from bottom to top more of the slope of flexion 4-2's arc concave surface design up and inclined plate portion 4-1 for the cold air is taken out fast, and the speed of upwards flowing is accelerated, accelerates the external air inflow, and the motor dispels the heat with higher speed.

Referring to fig. 7, the present embodiment is applied to the motor air outlet louver. The difference with the fan air inlet louver fan embodiment is that: the arc concave surface of the curved plate part 4-2 faces upwards, and the inclined plate part 4-1 is arranged obliquely downwards. The utility model discloses the inside fan work of blowing of cooperation motor, under the effect of fan of blowing, hot-air is from swash plate portion 4-1 downwards, because the flow direction of hot-air is from high to low, the arc concave surface of swash plate portion 4-1 downward design and flexion 4-2 designs wind path change that adapts to wind top-down more downwards for hot-air is blown off with higher speed, and the downward discharge rate is obviously quickened, and the hot-air discharge accelerates the motor heat dissipation.

In conclusion, the utility model discloses a two embodiments can know, baffle 4 forms a plurality of inlet air channel with the cooperation of 3 of scute, and 4-1 and 4-2 cooperation settings of bent plate portion of swash plate portion for wind gap wind path structure changes, adapts to the mobile mode of wind more for interior and external air flow, effectively reduces the wind noise that wind produced when the business turn over, has strengthened the business turn over wind effect of motor, has strengthened the motor heat dissipation.
