Description

Eddy flow ventilated machine

Technical field

This utility model is related to a kind of motor, more particularly to a kind of improvement of motor cooling structure.

Background technology

AC energy is converted to alternating current generator the mechanical energy for making motor shaft rotate at a high speed, meeting during this in the course of the work Substantial amounts of heat is produced, if heat is distributed motor not in time will be difficult to normal work, or even can also be burnt quickly.In electricity Some radiating ribs are provided with support, its effect is just to increase the area of dissipation of motor cabinet, so that motor quickly can be distributed Heat, while being also provided with radiator fan in motor rear end, the air-flow produced by radiator fan blows over radiating rib surface, so Distributing for motor cabinet heat can be accelerated, to obtain preferable radiating effect.Radiating rib generally on motor cabinet is mostly along motor Seat it is cylindrical circumferentially distributed, they or radially distributed centered on electrical axis or respectively radiate rib it is parallel each other, and Radiating rib is be arranged in parallel with electrical axis, additionally, the air-flow produced by radiator fan can only typically blow over motor rear end part Radiating rib surface, and the radiating rib surface of motor fore-end can not be reached, existing motor radiating structure has two The problem of aspect, one is that the layout of radiating rib can't make motor cabinet surface radiating area increase maximization, on the other hand, is dissipated Hot-air fan is uneven on motor length direction to motor cabinet quenching effect, and the radiating effect of motor front end is poor.

Utility model content

For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide a kind of rotation Stream ventilated machine, it can substantially increase the area of dissipation of motor seating face, improve radiating effect, while before and after ensureing motor End radiating is uniform.

In order to solve above-mentioned technical problem, a kind of eddy flow ventilated machine, including machine base body, electric machine main shaft, electric motor fan And some radiating ribs being arranged on machine base body outer surface, the radiating rib is in machine base body outer cylinder helically line Shape is distributed, and the periphery of radiating rib is provided with some wind guide covers, and the wind guide cover is arranged at intervals at adjacent two cooling fins top rib Between portion；Wind guide chamber is formed between two radiating ribs and wind guide cover and machine base body, the air intake of wind guide chamber is located in machine base body One end of neighbouring electric motor fan.

In said structure, due to it is described radiating rib machine base body outer cylinder helically wire distribution, then compared to The common radiating rib axially linearly along motor, the radiating rib that helically wire is distributed have longer rib long Degree, correspondingly the surface area of same radiating rib is bigger, and the area of dissipation on so whole motor seating face is also just bigger, electricity The radiating effect of machine is also just more preferably.Again due to being provided with some wind guide covers in the periphery of radiating rib, the wind guide cover interval sets It is placed between adjacent two cooling fins top rib portion, between two radiating ribs and wind guide cover and machine base body, forms wind guide chamber, wind guide chamber Air intake is located at one end of neighbouring electric motor fan in machine base body, then the cooling air-flow blown out by electric motor fan can be entered into be led Wind intracavity, the cooling air-flow into wind guide chamber can go ahead operation along wind guide chamber, until flow out wind guide chamber, can be with during this The heat in machine base body is taken away, the length of wind guide chamber determines the effective length to machine base body radiating, so by wind-guiding The setting of lid carrys out and radiates rib and forms wind guide chamber, and by wind guide chamber making cooling air-flow reach motor front end, so as to make Motor front end can also reach preferable radiating effect, it is ensured that the radiating of motor front and back ends is uniform.

A kind of preferred implementation of the present utility model, the zigzag shape radiating rib and machine base body outer cylinder bus Between angle α be 5 ° to 10 °.Using the embodiment, radiating rib length can be increased and two radiating ribs are can guarantee that Between leave appropriate radiating gap, such integral heat sink effect can guarantee that and get a promotion.

Another kind of preferred implementation of the present utility model, length B of the wind guide cover and the ratio B/ of radiating rib length L L is 1/4 to 3/4.Using the embodiment, the length of each wind guide cover can not be waited, and the wind guide chamber for being formed is to motor length side Radiate upwards to stress position also different, each position can obtain cooling radiating effect well from front to back also can just to make motor Really.

Another preferred implementation of the present utility model, length B of each wind guide cover have two kinds, a kind of wind guide cover Length B is 1/3 with the ratio B/L of radiating rib length L, and length B and the ratio B/L of radiating rib length L of another kind of wind guide cover are 2/3.Using the embodiment, length B of wind guide cover can be outstanding to motor rear end when being 1/3 with the ratio B/L of radiating rib length L Which is that good thermolysis is played at stage casing position, and the ratio B/L of length B of wind guide cover and radiating rib length L can when being 2/3 So that especially good thermolysis is played in motor front end to motor rear end, stage casing, and it is not provided with two radiating ribs of wind guide cover Between then directly receive the air-flow blown out by radiator fan, good thermolysis, so, motor are mainly played to motor rear end Before, during and after each position can obtain good cooling.

This utility model further preferred embodiment, in two wind guide cover Length discrepancies of adjacent position.Using the reality Mode is applied, the wind guide chamber formed by the wind guide cover of different length emphasizes particularly on different fields to the radiating effect at each position in motor length direction, So equally distributed effect, motor radiating effect can be circumferentially played in motor to the thermolysis at each position before, during and after motor Fruit is more preferably.

Another further preferred embodiment of this utility model, is overall knot between the wind guide cover and machine base body Structure.Using the embodiment, using the embodiment, wind guide chamber is simple for structure.

The another further preferred embodiment of this utility model, the wind guide cover are arranged in machine base body the rib that radiates On.Using the embodiment, wind guide chamber is assembling structure, and combination is convenient.
