Description
Technical field
The invention belongs to mechanical manufacturing field, be specifically related to a kind of centrifugal cutter and heat dissipating method.
Background technique
In machinery production process, centrifugal cutter is a kind of common heat dissipation equipment, and it relies on the mechanical energy of input, improves gas pressure and to supply gas side by side body, be a kind of driven fluid machinery, be usually applied to the cooling in the apparatus of air conditioning and domestic electric appliance and ventilation.
In prior art, the relevant design of existing centrifugal cutter.Fig. 1 is centrifugal cutter structural representation in prior art.As shown in Figure 1, each flabellum of centrifugal cutter is spaced from each other, in rotation process, easily produce return air, the hot blast got blows to commutator, cause commutator and carbon brush temperature in motor operation course higher, cooling-down effect is poor, thus shortens the working life of each device in motor.
Given this, the invention provides a kind of centrifugal cutter and heat dissipating method, to solve the problem.
Summary of the invention
The invention provides a kind of centrifugal cutter, comprise link, wheel rim, flabellum and cover plate, described wheel rim is hollow circle, described link is uniformly distributed in wheel rim bottom side, described flabellum is uniformly distributed in wheel rim top side and periphery, described cover plate is covered in above flabellum, and leaves formation air channel, space between described cover plate and each flabellum.
Preferably, described centrifugal cutter is installed on motor internal for heat transmission by link.
Preferably, described flabellum is arranged at wheel rim top side protrudingly, and extends to described wheel rim periphery.
Preferably, during described centrifugal cutter work, produce centrifugal force by rotating, heat is shed by the air channel between flabellum and cover plate.
Preferably, described centrifugal cutter is by the rotating shaft driven rotary in motor.
The present invention also provides a kind of heat dissipating method of centrifugal cutter, comprises the following steps.
Be installed on machine shaft by centrifugal cutter according to heat radiation position, drive fan turns during electric motor starting, described fan drives air flowing in motor casing, and forms air channel by cover plate, is discharged outside motor by hot gas.
According to centrifugal cutter provided by the invention and heat dissipating method, by covering cover plate above the flabellum of described centrifugal cutter, and leave space between cover plate and each flabellum, when motor runs, hot blast is formed air channel by fan turns, avoids return air to produce.So, effectively reduce the temperature of device in motor, promote motor working life.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is centrifugal cutter structural representation in prior art;
Fig. 2 is the centrifugal cutter overall schematic that present pre-ferred embodiments provides;

Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Fig. 2 is the centrifugal cutter overall schematic that present pre-ferred embodiments provides.As shown in Figure 2, the centrifugal cutter that present pre-ferred embodiments provides comprises flabellum 1, link 2, cover plate 3 and wheel rim 4, described wheel rim 4 is hollow circle, described link 2 is uniformly distributed in wheel rim 4 bottom side, described flabellum 1 is uniformly distributed in wheel rim 4 top side and periphery, described cover plate 3 is covered in above flabellum 1, and leaves formation air channel, space between described cover plate 3 and each flabellum 1.
In the present embodiment, flabellum 1 is arranged at wheel rim 4 top side protrudingly, and extends to described wheel rim 4 periphery.Described centrifugal cutter is installed on motor internal for heat transmission by link 2, and it is by the rotating shaft driven rotary in motor.During work, produce centrifugal force by rotating, heat is shed by the air channel between flabellum 1 and cover plate 3.
Fig. 3 is the centrifugal cutter sectional view that present pre-ferred embodiments provides.As shown in Figure 3, in the present embodiment, the cover plate cross section of described fan is horizontal plane, and in other embodiment, can arrange cover plate is that back is protruding or recessed.Composition graphs 2 and Fig. 3, link is plug-in type Wedge-shape connector, in other embodiment, can be rotation type screw or joint and clinging type link, but is not construed as limiting this present invention.
The heat dissipating method flow process of the centrifugal cutter that the present embodiment provides is: be installed on machine shaft by centrifugal cutter according to heat radiation position, fan turns is driven during electric motor starting, described fan drives air flowing in motor casing, and forms air channel by cover plate, is discharged outside motor by hot gas.In this, centrifugal cutter is divided into left-handed or right-spiral usually, in actual applications, according to the needs of design of electrical motor, decide the mounting type of fan in its sole discretion, but is not construed as limiting this present invention.
Fig. 4 is the centrifugal cutter application scenarios schematic diagram that present pre-ferred embodiments provides.As shown in Figure 4, centrifugal cutter A is installed in whole motor by rotating shaft D, also show motor internal and divide the device producing heat, such as rotor assembly B, commutator C and carbon brush E in Fig. 4.When centrifugal cutter A rotates, by the heat that assembly before and after it such as rotor assembly B, commutator C and carbon brush E produce, accelerate circulation and form air channel, flow out from centrifugal cutter A side.Thus effectively control each assembly temperature, avoid electric built-in temperature too high.
In sum, the centrifugal cutter provided according to present pre-ferred embodiments and heat dissipating method, by covering cover plate above the flabellum of described centrifugal cutter, and leave space between cover plate and each flabellum, when motor runs, hot blast is formed air channel by fan turns, avoids return air to produce.So, effectively reduce the temperature of device in motor, extend electric machine assembly working life.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to embodiment illustrated herein, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
