Abstract
The utility model relates to a heat radiation fan casing base, which is a heat radiation fan component, and the utility model can reduce the noise generated when a fan wheel rotates and can increase ventilation quantity. The utility model comprises a base plate which is provided with a positioning hole, an annular enclosing wall with a truncated conical inner wall surface is axially extended from the base plate, a base plate is arranged in the range which is enclosed by the annular enclosing wall, and the center of the base plate is provided with a pipe base which can be combined with a stator and a coil and can be pivoted with a fan wheel.
Description
The utility model belongs to ventilation cooling unit parts, particularly a kind of radiating fan casing seat.
As shown in Figure 5, traditional heat-dissipating fan system is included in the impeller 5 of rotation in shell block 6 internal ring walls 61, internal ring wall 61 is the seat board 62 of formation perpendicular to shell block 6 bottoms, and impeller 5 is incorporated on the seat board 62, and makes the flabellum 51 of impeller 5 and 61 of shell block 6 internal ring walls form discontiguous less gap.Therefore, during impeller 5 rotations of the heat-dissipating fan of this structure, make and produce the noise that wind is cut between flabellum 51 and the internal ring wall 61.
The purpose of this utility model provides a kind of reduce noise that produces when impeller rotates and the radiating fan casing seat that increases ventilation.
The utlity model has substrate, substrate is provided with positioning hole, is the ring enclosure wall of frustroconical from substrate axis to extending internal face, is provided with seat board in the scope of ring enclosure wall institute corral, seat board central authorities be provided with for stator, coil in conjunction with and articulate the base of impeller.
Wherein:
Be provided with the hole of being convenient to the installing and locating element corresponding to position of positioning hole on the ring enclosure wall.
The ring enclosure wall upwards extends from substrate, and inner wall surface thereof is the truncation turbination, and substrate and seat board are positioned at same horizontal position, to form big intake grill.
The ring enclosure wall extends downwards from substrate, and inner wall surface thereof is truncation normal cone shape, and seat board is positioned at the substrate below, to form big exhaust outlet.
The ring enclosure wall upwards extends internal face from substrate and is to be connected by truncation normal cone shape and truncation turbination and forms the ring enclosure wall that mid diameter is little, the two ends diameter is big, the seat board that in the scope of ring enclosure wall institute corral, is provided with, with formation bigger into and out of the air port.
Owing to the utlity model has substrate, substrate is provided with positioning hole, is the ring enclosure wall of frustroconical from substrate axis to extending internal face, is provided with seat board in the scope of ring enclosure wall institute corral, seat board central authorities be provided with for stator, coil in conjunction with and articulate the base of impeller.Be the frustroconical internal face by the ring enclosure wall, make the flabellum of impeller and encircle the gap that forms between the enclosure wall internal face along variable height, promptly equidistant gap, therefore, the wind in the time of can reducing the impeller rotation is cut noise, and can increase tuyere diameter, to increase ventilation.The noise that produces in the time of not only can reducing the impeller rotation, and can increase ventilation, thus reach the purpose of this utility model.
