Abstract
An air cooling motor whose front end cover is provided with cooling holes comprises a shell, a motor shaft, a front end cover, a rear end cover, a fan and a fan cover, wherein the outer surface of the shell is provided with multiple cooling ribs arranged at intervals and extending along the axial direction of the motor shaft; the adjacent two cooling ribs form an air flow channel; surrounding edges of a rear end surface of the front end cover exceed outwardly surrounding edges of the front end surface of the shell; the front end cover is provided with more than one cooling hole; and one end of each cooling hole extends to the rear end surface of the front end cover and passes through the air flow channel between the adjacent two cooling ribs, and the other end of each cooling hole extends to the front end surface of the front end cover. As the cooling holes are arranged in the front end cover, when air flow passes through the air flow channels to arrive at the front end cover, air flow enters the cooling holes, a large majority of heat on the front end cover is brought away when the air flow flows out of the cooling holes, and the air flow finally flowing out further brings heat on the connection end of a part connected with the front end cover.
Description
Technical field
The present invention relates to a kind of ventilated motor, specifically a kind of front end housing is provided with the ventilated motor of louvre.
Background technology
Motor is that the one that electric energy converts mechanical energy to is commonly used driving arrangement.Motor can produce a large amount of heat in running, therefore needs to install cooling body on motor.
The cooling body of existing motor is generally selected air-cooled, common ventilated motor is the one end of stretching out motor rear end plate fan being arranged on motor reel, the outer surface of motor casing is provided with the axially extended spaced apart radiating ribs of multiple tracks along motor reel, distinguished and admirable road is formed between adjacent two radiating ribs, fan is also covered with a fan guard outward, during motor running, fan turns, air enters from the air admission hole of fan guard, powerful air-flow is formed through fan, the air-flow formed under the gathering of fan guard along the wind flow passage between each radiating ribs, thus the most of heat walked by convective zone on motor casing, reach the object of cooling.
Although the ventilated motor of said structure can cool motor casing, but it is but very little for the cooling effect of motor front end housing, this is because motor front end housing is unsuitable for arranging radiating ribs on surface, during the outer surface of therefore airflow passes motor front end housing, little heat can only be taken away, cause cooling effect not good, impact run, especially when motor front end housing and other parts, as pump connect time, the link of motor front end housing, pump all can produce a large amount of heat, must cooling in time.
Summary of the invention
Technical problem to be solved by this invention is to provide the ventilated motor that a kind of front end housing all having a better cooling effect to casing and front end housing is provided with louvre.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: front end housing is provided with the ventilated motor of louvre, comprise casing, motor reel, front end housing, rear end cap, fan and fan guard, described front end housing is arranged on the front end of described casing, described rear end cap is arranged on the rear end of described casing, described motor reel is sleeved in described casing, and described rear end cap is stretched out in the rear end of described motor reel, described fan is arranged on the rear end of described motor reel, the outer surface of described casing is provided with the axially extended spaced apart radiating ribs of multiple tracks along described motor reel, distinguished and admirable road is formed between adjacent two radiating ribs, described fan guard covers on outside described fan, the edge of the rear end face of described front end housing outwards exceeds the edge of the front end face of described casing, described front end housing is provided with more than one louvre, one end of described louvre extends to the rear end face of described front end housing, and the distinguished and admirable road led between adjacent two radiating ribs, the other end of described louvre extends to the front end face of described front end housing.
Further, described louvre tilts towards the axis direction of described front end housing from back to front.
Beneficial effect of the present invention is: structure of the present invention is simple, to existing equipment change little, be easy to realize; The present invention owing to being provided with louvre on front end housing, therefore, when the distinguished and admirable road of air-flow between each radiating ribs arrives at front end housing, air-flow will flow in louvre, and the most of heat taken away when flowing out louvre on front end housing, reach the object of cooling front end housing, and the air-flow finally flowed out from louvre will flow through from the link of the parts be connected with front end housing further, thus the heat taken away on the link of these parts, therefore the present invention has good cooling effect to casing, front end housing and the link of parts that is connected with front end housing.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
For making simplified form, only schematically show part related to the present invention in each figure, they do not represent its practical structures as product.It will be apparent to those skilled in the art that the internal structure of motor also comprises the well-known components such as stator, rotor.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
The front end housing of one embodiment of the invention is provided with the ventilated motor of louvre, comprise casing 1, motor reel 2, front end housing 3, rear end cap 4, fan 5 and fan guard 6, described front end housing 3 is arranged on the front end of described casing 1, described rear end cap 4 is arranged on the rear end of described casing 1, described motor reel 2 is sleeved in described casing 1, and described rear end cap 4 is stretched out in the rear end of described motor reel 2, described fan 5 is arranged on the rear end of described motor reel 2, the outer surface of described casing 1 is provided with the axially extended spaced apart radiating ribs 11 of multiple tracks along described motor reel 2, distinguished and admirable road is formed between adjacent two radiating ribs 11, described fan guard 6 covers on outside described fan 5, the edge of the rear end face of described front end housing 3 outwards exceeds the edge of the front end face of described casing 1, described front end housing 3 is provided with more than one louvre 31, one end of described louvre 31 extends to the rear end face of described front end housing 3, and the distinguished and admirable road led between adjacent two radiating ribs 11, the other end of described louvre 31 extends to the front end face of described front end housing 3.
