Description
Technical field
The utility model relates to a kind of fluid-cooled electrical machine.
Background technology
In prior art, guarantee motor for the temperature rise that reduces motor and normally stably work, cooling device is installed on motor mostly, described cooling device generally is divided into two kinds of air-cooled and liquid cooling.Air cooling equipment is because noise is very large, and cooling effectiveness is not high, uses not extensive.Liquid cooling apparatus due to its noiselessness, cooling effectiveness is high is widely used.The liquid cooling apparatus that fluid-cooled electrical machine of the prior art adopts is all to adopt direct integral structure to be fixed on the shell of motor.Two kinds of the most frequently used mounting meanss are hot jacket and welding, and so-called hot jacket is inserted on motor housing after exactly cooling device heating being allowed it expand, thereby then allow it coolingly make it to tighten non-disconnectable being fixed on motor housing; Welding is directly cooling device to be welded on the shell of motor.Although it is easy to process that cooling device is fixedly connected on motor housing, cooling device also is not easy to leak, and Comparision is stable.But the medium that liquid cooling apparatus adopts is generally water and oil.Low price due to water, water-cooled is more common, the water cooling plant of take is example: from known, the words of water and metal Long Term Contact, metal surface can produce incrustation scale, and the principle of liquid cooling apparatus is exactly at the circulatory flow of motor housing setting around motor housing, make liquid in runner, circulate to take away the heat on motor.It is not very large that the bore of runner is subjected to spatial limitation, in runner, can accumulate very thick incrustation scale after motor uses a period of time, and incrustation scale can cause runner to stop up, and causes realizing circulating cooling, be exactly that incrustation scale is even without runner is stopped up in addition, cooling water can not directly be contacted with motor housing fully, because incrustation scale is attached to the motor housing surface, easily form a structure that is similar to heat-insulation layer, cause the cooling effectiveness of liquid cooling apparatus to reduce, the appearance of above-mentioned two situations makes the user often need the runner in the cleaning water cooling plant, and whole motor housing and water cooling plant are due to non-disconnectable, if adopt chemical method to clear up incrustation scale, can cause erosion to motor housing and cooling device again, so often can only change whole motor housing and water cooling plant.Same if oil cooling device, in cooling oil, often contain various impurity, motor in use also there will be the impurity in oil to stop up the situation of coolant flow channel, at this moment also needing to pull down cooling device clears up, oil cooling device of the prior art is non-disconnectable, and the user also can only change whole motor housing and oil cooling device.In sum, fluid-cooled electrical machine of the prior art exists the runner cleaning of cooling device inconvenient, the weak point that easily causes runner to stop up.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of runner cleaning of cooling device very convenient, is not easy the fluid-cooled electrical machine that causes runner to stop up.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of fluid-cooled electrical machine, it comprises motor housing, on described motor housing, liquid cooling apparatus is installed, described liquid cooling apparatus is a cover body with the looping pit be nested with motor housing, the annular hole wall of described cover body is provided with fluted flow channels, on runner, is communicated with inlet and liquid outlet, and an end of cover body is provided with the connector for being connected with motor housing; The junction of connector and motor housing is provided with the first sealing ring; The other end and the motor housing of cover body are tightly connected.
After adopting above structure, the utlity model has following advantage: described liquid cooling apparatus is removable the connection with motor housing, described removable connection refers to: described liquid cooling apparatus is a cover body with the looping pit be nested with motor housing, the annular hole wall of described cover body is provided with fluted flow channels, on runner, be communicated with inlet and liquid outlet, an end of cover body is provided with the connector for being connected with motor housing; The junction of connector and motor housing is provided with the first sealing ring; The other end and the motor housing of cover body are tightly connected.Liquid cooling apparatus is the sleeve type structure, after unclamping being connected between cover body connector and motor housing, namely can extract cover body out from motor housing, then the incrustation scale in the cover body inner flow passage and impurity etc. are cleared up, complete after cleaning and reinstalled again liquid cooling apparatus and get final product, due to liquid cooling apparatus is set can leak of sealing ring, so the utility model provides a kind of runner cleaning of cooling device very convenient, be not easy the fluid-cooled electrical machine that causes runner to stop up.
As preferably, described fluted flow channels is helical structure.The runner convection cell of helical structure is by better guiding function.
As preferably, the other end of described cover body is provided with seal cover, and seal cover and cover body and motor housing three's junction is provided with the second sealing ring.This structure make the other end of cover body very intact and motor housing between realized sealing, and syndeton simplify, solid and reliable.
As preferably, described connector is provided with a flange face, and described motor housing is provided with a step surface, and described flange face is fixedly connected with by screw with step surface, and the first sealing ring is between flange face and step surface.Flanged connector, degree of being connected firmly is high, and the contact area of connector and step surface is large, more firm between cover body and motor housing, is conducive to the sealing of sealing ring.
