Abstract

The utility model provides a motor cooling device, includes the shell, the flabellum, and its characterized in that: follow the outer circumference evenly distributed fin of shell, the fin is the metal material, and the fixed welding of one end is on the shell, and the other end is the free end, is bending near free end department the fin, the flabellum links to each other with the motor through the pivot, the length of flabellum at least and the fin flush. Through the fin that welding one end was bent on the circumference outside motor housing to extending to the flabellum size and flushing with the fin at least, at motor operation in -process, the fin heat dissipation can be accelerated to the wind that the flabellum blew out, and the heat with the motor production that so as to is timely distributes away, has lengthened the life of motor.

Description

Electric machine radiator

Technical field

This utility model relates to technical field of motors, particularly to a kind of heat abstractor being sleeved on outside motor.

Background technology

Motor can produce amount of heat during long time running, general by motor end and rotating shaft Connecting a flabellum to dispel the heat the pump housing, motor housing is made gear-like simultaneously, and (gear is equivalent to heat radiation Sheet), but the heat that this structural electromotor produces can only rely on the fin on shell slowly to carry out, and dissipates Thermal effect is poor, it is impossible to make the heat of generation distribute as early as possible.

Utility model content

Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that Yi Zhong electricity Machine heat abstractor.

Technical problem to be solved in the utility model uses following technical scheme to realize:

A kind of electric machine radiator, including shell, flabellum, is uniformly distributed heat radiation along described shell excircle Sheet, described fin is metal material, and one end is fixedly welded on shell, at distance other end end points about By fin bending at 1/4-1/5, wrap direction is contrary with direction of motor rotation, is found by contrast experiment Angle of bend radiating effect in the range of 100-130 degree is optimal.

Described flabellum is connected with motor by rotating shaft, and electric machine rotation drives flabellum to rotate, in order to have preferably Radiating effect, the length of described flabellum should at least flush with fin, during with electric machine rotation, The wind that flabellum produces is possible not only to dispel the heat motor side, and the most a part of wind can enter adjacent heat radiation In the passage of sheet, accelerate fin heat radiation.

The beneficial effects of the utility model are: by welding dissipating of one end bending on motor housing excircle Backing, and extend to fan blade size at least flush with fin, in motor operation course, flabellum blows The wind gone out can accelerate fin heat radiation such that it is able to is distributed by the heat that motor produces timely, Extend the service life of motor.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.

As shown in Figure 1, 2, a kind of electric machine radiator, including shell 1, flabellum 4, along shell 1 excircle Being uniformly distributed fin 2, fin 2 is metal material, and one end is fixedly welded on shell 1, another in distance By fin 2 bending at one end end points about 1/4-1/5, wrap direction is contrary with direction of motor rotation, passes through Contrast experiment finds that angle of bend radiating effect in the range of 100-130 degree is optimal.

Flabellum 4 is connected with motor by rotating shaft 5, and electric machine rotation drives flabellum 4 to rotate, and preferably dissipates to have Thermal effect, the length of flabellum 4 should at least flush with fin 2, during with electric machine rotation, flabellum 4 The wind produced is possible not only to dispel the heat motor side, and the most a part of wind can enter abutting fins 4 In passage, accelerate fin 4 and dispel the heat.

Of the present utility model ultimate principle and principal character and of the present utility model excellent have more than been shown and described Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned Principle of the present utility model is simply described, without departing from this utility model described in embodiment and description On the premise of spirit and scope, this utility model also has various changes and modifications, these changes and improvements In the range of both falling within claimed this utility model.This utility model claims scope by appended power Profit claim and equivalent thereof define.

Claims
