Abstract
The utility model discloses a heat dissipation centrifugal fan which comprises a machine enclosure, an impeller, an air inlet, a front cover plate, a rear cover plate, a heat dissipation wheel and a motor. The rear cover plate and a rear side plate of the machine enclosure of the fan are connected, a backing board is welded on the rear cover plate, the backing board and an end plate of the motor are connected, a cooling wheel is arranged between the rear cover plate and the end plate of the motor, and the cooling wheel is installed on a wheel hub of the impeller. The heat dissipation centrifugal fan has the advantages of being reasonable in structure, low in production cost, good in safety performance, convenient to dismantle and maintain, can capable of prolonging the service life of the centrifugal fan by means of the further installation of the cooling wheel on the centrifugal fan and the like.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of radiating type centrifugal blower.
Background technique
Centrifugal blower be utilize the mechanical energy of draught fan impeller rotation convert into gas pressure can and kinetic energy; And gas delivery gone out, gas produces air energy along the streamlined intake grill air inlet through hollow shaft of blower fan through the impeller rotation; Along the screw type housing gas is radially exported, seen off from the casing exhaust outlet again.Centrifugal blower is because fan rotor rotation speed is high, the generation heat can not get timely heat radiation, and the working life of this type blower fan is generally shorter.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, a kind of rational in infrastructure, long service life to be provided, the radiating type centrifugal blower of Security, good airproof performance.
Technological scheme: a kind of radiating type centrifugal blower; Comprise casing, impeller, intake grill, front shroud, back shroud, heat radiation wheel, motor; Said back shroud links to each other with the fan casing back side panel, is welded with backing plate on the said back shroud, and said backing plate links to each other with the end plate of motor; Between backing plate and motor end plate, be provided with the heat radiation wheel, said heat radiation wheel is installed on the wheel hub of impeller.
As preferably, said heat radiation wheel is semi-circular heat radiation wheel.
Beneficial effect: the utility model is rational in infrastructure, through on blower fan, setting up the heat radiation wheel, can effectively prolong the working life of blower fan, has advantages such as low preparation cost, Safety performance is good, dismounting is easy to maintenance.
Description of drawings
Accompanying drawing is the utility model example structure schematic representation.
Embodiment
Below in conjunction with specific embodiment the utility model is described further:
Shown in accompanying drawing, a kind of radiating type centrifugal blower comprises casing, impeller 1, intake grill 2, front shroud 3, back shroud 4, heat radiation wheel 5, motor 6; Said back shroud 4 links to each other with the fan casing back side panel; Be welded with backing plate 7 on the said back shroud 4, said backing plate 7 links to each other with the end plate of motor 6, between backing plate 7 and motor 6 end plates, is provided with heat radiation wheel 5; Said heat radiation wheel 5 is installed on the wheel hub of impeller 1, and said heat radiation wheel (5) is semi-circular heat radiation wheel.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
Claims (2)
