Technical solutions of the utility model are by heat conductor and fin, in weight reduction, corrosion resistance, radiating rate that makes motor casing etc. is improved, by the first draw-in groove, the second draw-in groove, the 3rd draw-in groove and the 4th draw-in groove, motor and external equipment are connected together, improve the speed of installation and removal, further improved operating efficiency; Heat conductor, fin by one-body molded, have reduced processing technology in addition, have improved operating efficiency; Coordinate in addition the special construction of fin by heat conductor special construction, make the radiating effect of motor casing obtain better lifting.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of motor casing of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of motor casing described in the utility model comprises:
A kind of motor casing comprises:
The heat conductor 1 of ring-type;
N fin 2 is arranged on the outer surface of heat conductor 1, and N is the positive integer greater than 1;
For the first draw-in groove 3, the second draw-in groove 4, the 3rd draw-in groove 5 and the 4th draw-in groove 6 that are connected with external equipment, be arranged on the outer surface of heat conductor 1.
By heat conductor 1 and fin 2, in weight reduction, corrosion resistance, radiating rate that makes motor casing etc. is improved, by the first draw-in groove 3, the second draw-in groove 4, the 3rd draw-in groove 5 and the 4th draw-in groove 6, motor and external equipment are connected together, improve the speed of installation and removal, further improved operating efficiency.
Fin 2 is arranged on heat conductor 1 outer surface, and concrete number sets according to corresponding movement, heat conductor 1 outer surface up and down four direction respectively correspondence be provided with the first draw-in groove 3, the second draw-in groove 4, the 3rd draw-in groove 5 and the 4th draw-in groove 6; At erection stage, heater is placed in heat conductor 1, heater is specially the motor part in motor in the present embodiment, is being fixed with external equipment respectively by the first draw-in groove 3, the second draw-in groove 4, the 3rd draw-in groove 5 and the 4th draw-in groove 6; During work, the motor rear rotation of partly switching on produces heat in rotation at a high speed, and the heat of generation is sent to fin 2 by heat conductor 1, by fin 2, the heat that produces is discharged to the external world, thereby is embodied as heat radiation, the cooling of heater.
Preferably, also comprise:
N installing hole is separately positioned in draw-in groove, and N is the positive integer greater than 1;
Be used for passing installing hole, make the fixing more firmly fixture of heat conductor 1 and external equipment.
Can more firmly fix for guaranteeing motor casing and external equipment, so punch the formation installing hole by instruments such as electric drills respectively in the first draw-in groove 3, the second draw-in groove 4, the 3rd draw-in groove 5 and the 4th draw-in groove 6, the concrete number of installing hole is decided according to the use needs of reality, this is not limited in the utility model, at erection stage, fixture passes installing hole, and motor casing and external equipment are fixed together.
Preferably, heat conductor 1 and fin 2 are one-body molded.
