Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a motor housing. Background Art

[0002] The commonly used water-cooled structure motor housing is a motor base shell with several annular grooves set at intervals, and the annular grooves are covered with sealing plates to form cooling water channels. Liquid will continue to flow through the water channels to carry away heat, and long-term water flow will lead to the formation of water pipes, which are easy to block the water channels. The water channels are annular in shape, making them more difficult to clean when blocked.

[0003] In order to solve the above problems, the utility model patent with authorization announcement number CN219181302U discloses a motor housing with a water-cooling structure, which reduces the frequency of water channel blockage in the housing, reduces the possibility of the housing being unusable due to blockage, makes it easier to clean scale from the housing, and improves the sealing of the device to reduce the possibility of water leakage.

[0008] In order to ensure the installation stability of pressure plate 1 and pressure plate 2;

[0009] As a further improvement of the above technical solution: the screws are arranged at intervals on the end surface of the motor housing between adjacent heat exchange chambers.

[0010] The beneficial effect of this improvement is that the use of multiple screws in conjunction with nuts can achieve stable locking of the pressure plate one and the pressure plate two.

[0011] In order to ensure the sealing of the pipeline composed of pressure plate 1, pressure plate 2 and hot water exchange pipe;

[0012] As a further improvement of the above technical solution: a sealing ring is sleeved on the plug-in end and the threaded end.

[0013] The beneficial effect of this improvement is that the sealing ring plays a sealing role at the connection between the hot water exchange pipe and the pressure plate 1 and the pressure plate 2.

[0020] In order to ensure the heat dissipation effect of the hot water exchange pipe;

[0021] As a further improvement of the above technical solution: the number of the heat exchange water pipes is multiple, and they are opened in an equal order in the circumferential direction around the axis of the motor housing.

[0022] The beneficial effect of this improvement is that the multiple heat exchange water pipes cooperate with the heat exchange chamber inserted therein to achieve uniform cooling of the motor housing.

[0023] In order to ensure the heat dissipation effect of the hot water exchange pipe;

[0024] As a further improvement of the above technical solution: the surface of the heat exchange water pipe is coated with a thermal conductive silicone grease layer with a thickness of 0.5 to 1 mm.
