Description

A kind of water-cooled machine
Technical field
The present invention relates to electric motors, more particularly to a kind of water-cooled machine.
Background technology
The range of application of motor is wider, particularly in recent years, as China promotes manufacturing industry transition and upgrade, in various intelligence In manufacture field, with motor as power and carry out drive control automation equipment automaticity more and more higher.This Under trend, the requirement of the equipment of every profession and trade to motor also more and more higher, for example, efficiency high, power density are big.But motor is in length In the operation process of time, problem of temperature rise often governs the Effec-tive Function of motor, further can also reduce the use longevity of motor Life.
In the motor course of work the reason for generation heat including bearing friction, coil resistance, iron core magnetic resistance etc., when motor temperature When spending high, motor operation can be caused to break down, the service life of serious curtailment motor.At present to the conventional side of electric motor temperature reduction Formula includes self-cooled, air-cooled and water-cooled.Self-cooled is applied to the small motor of heat production, and air-cooled heat-sinking capability is limited. All without directly contact, there is air centre to the stator winding and casing and end cap of motor, and the heat transfer coefficient of air is very low, heat transfer Poor ability, stator winding and stator contact, so its heat can only first be conducted to stator, then are conducted to outside by stator Casing, when causing motor to work, shell temperature is not high, but motor internal temperature phenomenon still very high.Therefore some motors Drive end bearing bracket and rear end cap be provided with air inlet and gas outlet, coordinate the fan on the outside of rear end cap to radiate motor, but Between back end cover for motor and stator and rotor and neighbouring heat cannot shed immediately, the radiating effect of motor housing is not in addition It is preferable.
The content of the invention
Motor housing radiating effect can be taken into account it is an object of the invention to provide one kind and avoid along electrical axis direction The water-cooled machine that region heat is excessively concentrated, by with shell fit set the first water-cooled portion and with rear end cap outer surface Second water-cooled portion of contact coordinates the fan in rotating shaft to realize the purpose.
In order to reach the purpose, the present invention is adopted the following technical scheme that:Including pedestal, be fixed on it is outer on the pedestal Shell, drive end bearing bracket and rear end cap, the shell, the drive end bearing bracket and the rear end cap constitute inner chamber, through the drive end bearing bracket and institute State rear end and be covered with rotating shaft, rotor is installed in the rotating shaft, stator, the stator are provided with around the rotor in the inner chamber It is close to set with the shell, gap is provided between the rotor and the stator, it is characterised in that:The drive end bearing bracket be provided with into Gas port, the rear end cap is provided with gas outlet, and also including heat abstractor, the heat abstractor includes water-cooled part, the water-cooled part The the second water-cooled portion contacted including the first water-cooled portion set with shell laminating and with the rear end cap outer surface, by institute State the second water-cooled portion and be outwards sequentially provided with the fan and fan guard being fixed in the rotating shaft.
Thus, water inlet of the cold water in the second water-cooled portion from rear end cap is flowed into and from the draining of the first water-cooled portion end Mouth discharge, the heat that fan will be more than is discharged to outside electric machine.
Dividing plate is preferably provided with the second water-cooled portion as a kind of, the second water-cooled part is divided into two by the dividing plate Cavity, each described cavity is provided with a water inlet, and the first water-cooled portion is provided with delivery port.
Thereby it is ensured that uniformly mixing along the cooling water of motor circumferential direction, it is to avoid regional hot water aggregation is not discharged for a long time Situation.
As one kind preferably, the dividing plate is vertically arranged, and the water inlet is located at the second water-cooled portion middle part.
As it is a kind of preferably, the first water-cooled portion include parallel to the rotating shaft rotation axis cooling tube and with institute State the drain chamber that the second water-cooled portion is oppositely arranged.
Thus, it is easy to wind to pass through the cooling tube being disposed adjacent to be radiated with it.
Used as a kind of preferred, also including supporting member, the supporting member is located between the cooling tube and the shell, described Supporting member is fitted setting with the shell.
Thus, supporting member ensure that the stability of heat abstractor and the relative position of motor, while preferably transmitting motor Heat on shell.
As one kind preferably, the cooling tube is flat tube, and the thickness of the flat tube is 1.5-2.0mm.
As one kind preferably, the size of the exhaust outlet is 0.5-4.0mm.
As one kind preferably, the air inlet and the gas outlet are provided with screen pack.
Thus, it is to avoid dust and other impurities enter motor internal.
To sum up, the present invention has advantages below:The supporting member for setting of being fitted with motor housing outer surface ensure that radiating dress The positional stability put, while coordinating the radiating effect that ensure that motor housing with flat tube;Second water of the cold water from rear end cap Water inlet in cold portion is entered and discharged from the discharge outlet of the first water-cooled portion end, it is to avoid the heat aggregation near rear end cap, Ensure that along the uniform of electrical axis direction region heat.
