Background
At present, the cooling modes of the motor mainly comprise natural cooling, air cooling, water cooling and the like. When the high-power motor works, the motor stator can generate a large amount of heat energy, and the general cooling mode can not take away enough heat energy, so that liquid cooling is needed. Most of the prior art is to provide a water channel in a stator housing and introduce a cooling liquid to cool the stator housing and a stator. The arrangement of the water channel between the stator and the stator shell needs to additionally increase the overall dimension of the stator shell, which increases the weight and cost of the whole motor and the processing time of the stator shell.

the utility model provides a motor cooling casing based on continuous water pipe, includes stator housing and condenser tube, sunken heliciform pipeline has been seted up to stator housing's inner wall, the condenser tube is laid the other end that heliciform pipeline was laid from the one end of heliciform pipeline to inside and the condenser tube of heliciform pipeline, condenser tube's inboard pipe wall with the pipe wall laminating of heliciform pipeline, condenser tube's outside pipe wall flushes with stator housing's inner wall.
As a further improved technical proposal of the utility model, the cooling water pipe adopts a continuous copper pipe.
As a further improved technical scheme of the utility model, condenser tube is laid through the mode of impressing inside the heliciform pipeline.
The utility model has the advantages that:
(1) the stator shell is a section bar, the shape of the pipeline is directly processed, the processing difficulty is low, and the die sinking casting similar to the traditional requirement is not needed. The cost and the construction period are reduced, the manufacturing quantity can be flexibly changed according to the production order, and the size can be flexibly changed.
(2) The cooling duct is disposed on the stator housing, adjacent to the coil. This increases the cooling efficiency. The cooling pipeline adopts a spiral shape, so that the adverse effects of water scale and generated water scale are reduced.
(3) The cooling water pipe is a copper pipe, has strong corrosion resistance, is not easy to oxidize, is not easy to chemically react with some liquid substances, is easy to be subjected to bright bending modeling, is convenient to install, has small linear expansion coefficient, and cannot cause stress fatigue fracture due to excessive thermal expansion and cold contraction. The cooling water pipe is continuous and has no connection structure in the middle. The sealing performance is guaranteed, night leakage is avoided, and the problems of a cooling pipeline are reduced.
(4) And the cooling water pipe is installed in an extruding mode, so that the copper pipe is completely attached to the shell, and no protruding part exists. This greatly increases the cooling efficiency and does not take up excess space.

Detailed Description
The following further description of embodiments of the present invention is made with reference to the accompanying drawings 1-3:
as shown in fig. 1 to 3, a motor cooling housing based on a continuous water pipe comprises a stator housing 1 and a cooling water pipe 3, wherein a recessed spiral pipeline 2 is processed on the inner side of the stator housing 1, the cooling water pipe 3 is laid inside the spiral pipeline 2, and the cooling water pipe 3 is laid from one end of the spiral pipeline 2 to the other end of the spiral pipeline 2. As shown in fig. 3, the inner wall of the cooling water pipe 3 is attached to the wall of the spiral pipe 2, and the outer wall of the cooling water pipe 3 is flush with the inner wall of the stator housing 1.
In this embodiment, the cooling water pipe 3 is a continuous copper pipe.
In this embodiment, the cooling water pipe 3 is laid inside the spiral duct 2 by press-fitting.
As shown in fig. 3, the cooling water pipe 3 is pressed into a partial cross section of the stator housing 1 for the fixture 4. The cooling water pipe 3 is pressed into the stator housing 1 in advance according to the spiral shape of the pipeline 2 in the stator housing 1, and then the tool 4 is used for pressing the cooling water pipe 3 until the cooling water pipe 3 is completely attached to the pipe wall. The tool 4 flattens the protruding part of the cooling water pipe 3 until the protruding part is flush with the stator shell; the tool 4 rotates to press fit all the cooling water pipes 3, and the cooling water pipes 3 cannot be damaged during press fitting.
The cooling liquid enters from the inlet of the cooling water pipe 3, cools the stator housing 1 through the spiral surrounding pipe 2, and then flows out from the water pipe 3 of the cooling pipe 2.
The embodiment has the following characteristics:
the stator shell 1 is a section bar, the shape of the pipeline 2 is directly processed, and die sinking casting similar to the traditional requirement is not needed. The cost and the construction period are reduced, the manufacturing quantity can be flexibly changed according to the production order, and the size can be flexibly changed. The cooling duct 2 is provided on the stator housing 1, close to the coils. This increases the cooling efficiency. The cooling pipeline 2 adopts a spiral shape, so that the scale and the adverse effect after the scale is generated are reduced. The cooling water pipe 3 is a copper pipe, has strong corrosion resistance, is not easy to oxidize, is not easy to chemically react with some liquid substances, is easy to be subjected to bright bending modeling, is convenient to install, has small linear expansion coefficient, and cannot cause stress fatigue fracture due to excessive thermal expansion and cold contraction. The cooling water pipes 3 are continuous without a connection structure in between. This guarantees sealing performance, and the night that can not appear leaking has reduced the problem that cooling tube 2 appears. And the cooling water pipe 3 is installed in an extruding mode, so that the copper pipe is completely attached to the shell, and no protruding part exists. This greatly increases the cooling efficiency and does not take up excess space.
