Abstract

A double-channel heat-dissipating structure of a deflector-type motor housing, which provides more than one T-shaped heat dissipating fin around the outboard of the motor housing in a circular manner. A tapered double-arc heat-dissipating room is formed between two T-shaped dissipating fins, having a short-trimmed auxiliary flat heat-dissipating fin in the middle; a smooth cool/hot air exchange and convection is ensured to eliminate swiftly the heat generated by the motor running and improve heat-dissipating performance with T-shaped heat-dissipating fins and auxiliary flat heat-dissipating fins that allow heat transmission and dissipation and air retention generated by the double-arc heat dissipating room.

Description

The dual channel radiator structure of flow-guiding type motor shell

[technical field]

The utility model is the radiator structure about a kind of motor shell, is meant a kind of dual channel radiator structure of flow-guiding type motor shell especially.

[background technology]

Motor is a kind of important tool that converts electric energy to kinetic energy, and transfer process will certainly produce heat energy, motor running speed is higher, the heat energy that forms will be healed greatly, how to dispel the heat is the problem that often faces on motor uses, so the excellent, bad of motor heat dispersion is the important key that influences its power output; The motor configuration of earliest period, see also shown in Figure 1, conventional motor shell 10 is the housings 11 that comprise a circle footpath shape, and at the more than one flat fin 12 of housing 11 peripheral formation, this fin 12 is equidistant toroidal shape and distributes, and therefore can form a diversion space 13 between fin 12, it is to utilize radial annular tabular fin 12, heat energy that motor running produced to outdiffusion, and is entered diversion space 13 by air and carries out convection current, reach the purpose of heat radiation; But because the area of dissipation of tabular fin 12 is too little, with and diversion space 13 capacity that can enter for air little, and convective air flow is lost because of not having a block resistance, make the heat radiation function of this structure limited, nowadays the rotating speed of motor and power make conventional motor shell 10 can't satisfy the demand of present use in continuous lifting; So people improve motor case, see also shown in Figure 2, it is the Taiwan number of patent application: 086213067 " improvement of flow-guiding type motor shell ", this flow-guiding type motor case 20, the housing 21 that comprises a circle footpath shape, and at the more than one leg-of-mutton fin 22 of housing 21 peripheral formation, this fin 22 is equidistant toroidal shape and distributes, and can form leg-of-mutton diversion space 23 between two fin 22.The motor case 20 of this structure, be to see through radial annular triangle fin 22, with the leg-of-mutton big limit face of motor thermal energy conduction to fin 22, utilize this big limit face to disperse heat energy fast, and same diversion space 23 triangular in shape, in big outer little, can produce a little after air is entered and be detained, so its radiating effect is preferable; Thereby efficiently solve heat dissipation problem and reduced the motor failure rate, make its performance be better than conventional motor, but after practical application, find, because of fin 22 and diversion space 23 all triangular in shape, make the convection current of air smooth and easy inadequately and then influence the conduction of heat energy ground greatly, can't reach desirable heat radiation purpose.

[novel content]

The utility model is to provide the big and cross-ventilation of a kind of area of dissipation dual channel radiator structure of flow-guiding type motor shell smoothly.

The utility model solves the problems of the technologies described above by the following technical programs: in the motor shell periphery, the circular row more than one T shape fin that distributes equably, and between two T shape fin, form big outer little two arc heat-dissipating spaces in, and install the tabular heat radiation supplementary plate of a cutting back formula in this heat-dissipating space interposition.Can increase the area of dissipation that contacts with air, and utilize two curved edges of heat-dissipating space, quicken the convective exchange of hot and cold air, the high efficiency and heat radiation effect is provided.

Wherein, T shape fin is all contour.

Advantage of the present utility model is: because heat-dissipating space adopts two arc designs, make air do slightly to be detained and form smooth and easy drainage loop simultaneously, not only can make T shape fin be easier to heat radiation, more can make the convective exchange of hot and cold air not interrupted, therefore can significantly promote radiating effect.

[embodiment]

Please consult Fig. 3, Fig. 4 and Fig. 5 simultaneously, be the utility model one embodiment, periphery at a motor shell 30 is peripheral, the equidistant circular row more than one contour T shape fin 31 that distributes, and between two T shape fin 31, form big outer little two arc heat-dissipating spaces 32 in, and, constitute a dual channel radiator structure 40 thus at the tabular that these heat-dissipating space 32 interpositions install the cutting back formula supplementary plate 33 that dispels the heat; Because contour T shape fin 31 and tabular heat radiation supplementary plate 33, its heat conduction velocity is unequal, can make the thermal diffusivity of this structure can not produce conflict; Utilize two 32 couples of air A of arc heat-dissipating space that the effect of dispersion delay (do not form hot-air A and build up phenomenon) is arranged again, then can carry out the exchange convection current of hot and cold air A smoothly, the heat energy that motor running is produced, can distribute rapidly to motor shell 30 outsides, and then reach the purpose (seeing for details shown in Figure 4) that improves heat radiation function; As shown in Figure 5, be the situation of the utility model structure applications in the ventilation type motor, establish a platform 53 on the motor shell 30 that Fig. 5 disclosed and be convenient to install an electric control box 54, an end of motor body 50 forms conjoint disk seat 51 simultaneously, a motor spindle 52 is extended in these conjoint disk seat 51 outer faces, the other end that is different from conjoint disk seat 51 then is a fan cover 55, the fan when motor running in the fan cover 55 also simultaneously the running, make cross-ventilation and strengthen the heat radiation.

In addition, please cooperate again and consult Fig. 6 and Fig. 7, be the embodiment of the utility model structure applications in liquid-cooled motor 60, this motor shell becomes cylinder-like shell, these cylinder-like shell both ends of the surface and peripheral cover constitute the drum external member 63 of closed, reach cooling effect for cooling fluid circulates in the interior space of sealing.Wherein the drive end of motor spindle 62 is established a conjoint disk seat 61, the other end is then established an electric control box 7, cooling fluid inlet 71 and cooling liquid outlet 72, this cooling fluid inlet 71 and cooling liquid outlet 72 are communicated with the interior sky that drum external member 63 forms sealing, in the injection of cooling fluid and between expulsive stage, this cooling fluid can be in two arc heat-dissipating space 32 internal flows, and reach the cooling effect (please refer to Fig. 7) of circulation.

In sum, the equidistant circular row of the utility model utilization distributes and is contour more than one T shape fin and tabular heat radiation supplementary plate, provide thermal conduction rate different thermolysiss, and by formed pair of arc heat-dissipating space between two T shape fin, can the smooth and easy convective exchange of finishing hot and cold air effectively.
