Abstract

The utility model relates to a motor shell body heat-radiating structure which is the improvement on the motor shell body heat-radiating structure and makes the heat-radiating structure of a motor shell obtain better heat-radiating effect. The utility model is mainly characterized in that two inclined heat-radiating fins which are integrally formed are arranged on the outside end of a vertical heat-radiating fin of the shell body to form two inclined heat-radiating surfaces. The heat-radiating surfaces of the utility model are increased by the two inclined heat-radiating surfaces, and the heat-radiating efficiency of the utility model is further increased.

Description

The motor shell radiator structure

Technical field

The utility model relates to the motor shell radiator structure, and it makes the Structure of radiating fin of motor shell obtain better radiating effect.

Background technology

Known motor shell Structure of radiating fin as shown in Figure 1, is that the outer peripheral face of housing 1 is laid spaced many vertical fins 2, is formed with airslide 3 therebetween, is increased area of dissipation by each vertical fins 2; There is following shortcoming in fact in said structure:

(1) its area of dissipation, non-is maximum, for example: the area of dissipation than Fig. 2 is little.

(2) its nameplate 4 directly sticks in strip vertical fins 2, is to be the bonding that " point " reaches " the both-end side strip is unilateral ", and glutinous to decide effect relatively poor.

Therefore, the improvement of more progressive person such as Fig. 2 being arranged, is vertical fins 11 outer ends that housing 10 is laid, and adds integrated horizontal fin 12, is formed with airslide 13 therebetween, increases area of dissipation by horizontal fin 12.But it has following shortcoming:

(1) though its area of dissipation has horizontal fin 12, because of its end face is " plane 120 ", so still non-be maximum, the leeway of improvement is still arranged, for example: littler than area of the present utility model.

(2) strip of sheet (like vertical fins) nameplate spacer 5 still need be established for glutinous fixed in the location of its nameplate 4, so be still the bonding that " point " reaches " the both-end side strip is unilateral ", sticks that to decide effect relatively poor.

(3) again, its horizontal fin 12 will be derived and be reduced the problem in airslide 13 spaces, influence the effect of circulation of air heat radiation.

The utility model content

The purpose of this utility model provides a kind of motor shell radiator structure, be the outer peripheral face of housing have be covered with, many vertical fins at interval, each vertical fins outer end is provided with the strip of sheet fin; It is characterized in that: the strip of sheet fin in each vertical fins outer end is to be set as upwardly, and obtains not reduce the two oblique fin in airslide space, and the outer face of two oblique fin is formed with two oblique radiating surfaces of increase area of dissipation.

By said structure, the utility model can be realized following technique effect:

One, each the vertical fins outer end with housing is provided with the oblique fin of two oblique shapes, and is formed two oblique radiating surfaces, reaches the effect that increases area of dissipation, therefore can obtain to promote the good effect of heat radiation.

Its two, with the glutinous silver of decide nameplate of housing, be set as large-area nameplate location dough sheet, be formed with the airflow space of hollow, and obtain to locate the effect of nameplate and excellent in heat dissipation effect.

Fig. 3 is the utility model preferred embodiment structure cutaway view.

Fig. 4 is another kenel of the utility model embodiment cutaway view.

Fig. 5 is that the utility model adds auxiliary tank embodiment cutaway view.

Embodiment

See also Fig. 3, motor shell radiator structure of the present utility model, be the outer peripheral face of housing 20 have be covered with, many vertical fins 21 at interval, be formed with airslide 26 therebetween; Wherein, the outer face of establishing upswept

oblique fin

22,23, the two

oblique fin

22,23 of one-body molded two strip of sheet in the outer end of each vertical fins 21 is formed with two oblique radiating surfaces 24,25.

Moulding of the present utility model can be adopted " aluminium extruded type " mode moulding long column shape, again according to the Len req severing, also can directly adopt mould " casting " moulding.Structure kenel of the present utility model is had following effect, advantage:

(1) air still can circulate in the space of airslide 26, reaches radiating effect.

(2) except having the two bottom surfaces heat radiation of vertical fins 21 two sided, two

oblique fin

22,23, more increase " the two oblique radiating surfaces 24,25 " that two

oblique fin

22,23 are arranged, in other words, the area of two oblique radiating surfaces 24,25 is greater than " plane 120 " radiating surface of Fig. 2, and heat radiation function is promoted in acquisition.

(3) because of two

oblique fin

22,23 are set as " upward ", so image pattern 2 does not reduce the space of airslide, still can keep the airslide 26 of large space, and the good effect that must maintain the circulation of air.

Again, the utility model still can be following enforcement kenel, and it belongs to the category of the utility model equivalent structure:

(1) as shown in Figure 3, system can be in housing 20 settings place, if integrated large tracts of land nameplate location dough sheet 27, be formed with the airflow space 270 of large space therebetween, decide nameplate 4 and get large tracts of land for sticking, making it, glutinous decide effect preferable, and the airflow space 270 because of large space is arranged, and the acquisition good radiating effect that maintains the circulation of air.

(2) as shown in Figure 4, be the outer face of two

oblique fin

22,23 can be set as concavity arc radiating surface 28, this arc radiating surface 28 also obtains the effect than plane increase area of dissipation.

(3) as shown in Figure 5, be 21 of two

oblique fin

22,23 and vertical fins can be established the auxiliary tank 29 of separation, also can increase the effect in area of dissipation and circulation of air space.

Claims
