Embodiment Construction

[0025] Specific embodiments of the present invention will be further described in detail below.

[0026] Such as Figure 1 to Figure 3 As shown, a cooling jacket of the present invention includes a cylindrical casing 10 . The cover body 10 is made of light materials such as aluminum, aluminum alloy, copper or copper alloy, so as to avoid adding too much weight. In addition, the casing 10 has a certain thickness, which is a common thickness in the industry at present, and can be obtained through simple tests according to the size, heat dissipation and processing conditions of the motor (of course not limited to the motor only). Thickness is a parameter that can be obtained without creative labor. A pipe 12 is arranged inside the casing 10 along its circumference, and a cooling liquid inlet 14 and a cooling liquid outlet 16 communicating with the pipe 12 are arranged on the casing 10 . In this way, it can be realized to use cooling liquid, such as water, to cool the motor. I...

Abstract

The invention discloses a cooling sleeve which comprises a cylindrical sleeve body. The sleeve body has a certain thickness. A pipeline allowing cooling liquid to flow in the pipeline is arranged in the sleeve body in the circumferential direction. The sleeve body is provided with a cooling liquid inlet and a cooling liquid outlet, and the cooling liquid inlet and the cooling liquid outlet are communicated with the pipeline. The cooling sleeve is characterized in that the sleeve body is formed by bending a flat board and welding the two ends of the bent flat board. A manufacturing method of the cooling sleeve is completely different from a welding method after casting and machining. The cooling sleeve is machined in a mode that the flat board with the pipeline is firstly manufactured, and then bending and welding are carried out. The cooling sleeve can effectively avoid defects existing in a traditional machining method, and has the advantages of being low in machining cost, attractive in appearance, high in heat dissipation efficiency and the like.

Description

technical field [0001] The invention relates to a cooling jacket, in particular to a cooling jacket on a motor. Background technique [0002] The rotor on the motor or other similar mechanisms will generate a lot of heat during high-speed operation. In order to keep the motor running at its best, it must be cooled. For this reason, many institutions have all carried out a large amount of researches, as patent CN103001398 and CN103138486. Their solutions are all to add a cooling jacket to the motor, and the cooling jacket is provided with a coolant pipe to cool the motor through the coolant. In fact, when processing this kind of cooling jacket, there are usually two processing methods: casting and non-casting. During casting, it is necessary to take out the sand core that forms the pipe part from the finished product after casting, which is very time-consuming; in addition, sand holes are easy to form in casting, which may easily lead to liquid leakage during use. In the ...
