[0029] Obviously, the described embodiments are only part of the embodiments of the utility model, not all embodiments, based on the embodiments of the utility model, other embodiments obtained by the person skilled in the art without creative labor all belong to the protection scope of the utility model. The various technical features in the utility model can be combined interactively without mutual contradiction and conflict.

[0030] Referring to Figure 1 and Figure 5 , the utility model embodiment proposes a kind of rust-proof water cooling jacket, can solve the problem that the internal flow passage of existing motor water cooling jacket is easily corroded, to reach good cooling heat dissipation effect.

[0031] In the present embodiment, rust-proof water cooling jacket includes shell 100 and pipeline 300. Wherein, referring to Figure 2 , pipeline 300 is stainless steel piece, it is spirally arranged, can guide cold water spiral flow.Referring to Figure 3 and Figure 4 , shell 100 is aluminum alloy material casting, and its center is provided with installation cavity 110, installation cavity 110 is through at the both ends of shell 100 along length direction, and installation cavity 110 is used to install motor.The inside of shell 100 is also provided with pipe cavity, and pipeline 300 is located in pipe cavity, and shell 100 is arranged by casting process, so that pipe cavity is spirally arranged along the outer periphery of pipeline 300, and pipe cavity is located at the outside of installation cavity 110, and is separated from installation cavity 110 by the inner wall of shell 100.The peripheral wall of shell 100 is also provided with two water guide openings 140, and two water guide openings 140 are respectively communicated with the head end and tail end of pipeline 300, and the orientation of two water guide openings 140 is kept consistent, and the direction of head end opening and tail end opening of pipeline 300 is kept consistent.

[0032] When cold water flows through pipe 300, it removes heat from the motor within mounting cavity 110, preventing it from overheating. Because pipe 300 is made of stainless steel, water flowing along pipe 300 is less likely to corrode it, allowing the water to spiral around the outside of the motor, ensuring effective heat dissipation.

[0033] Furthermore, the consistent orientation of the water guide ports 140 facilitates water flow in and out, and allows the pipe 300 to be properly positioned within the casting mold of the housing 100. During the production of the rust-proof water-cooling jacket of this embodiment, the pre-processed spirally arranged pipe 300 is pre-embedded in the mold, and after the aluminum alloy is cast, the housing 100 is machined. It is understood that the machined surface of the housing 100 must be deburred and free of scratches and dents.

[0034] In some embodiments, the rust-proof water cooling jacket further includes a water guide platform 200, referring to Figure 1 、 Figure 2 and Figure 5 There are two water guide platforms 200, each of which is provided with a water guide groove 210. The two water guide platforms 200 are respectively welded to the head end and the tail end of the pipeline 300. The water guide groove 210 is connected to the pipeline 300. The notches of the two water guide grooves 210 are located on the same plane, that is, the non-pipeline 300 connection end surfaces of the two water guide platforms 200 are located on the same plane.

[0035] It is understandable that the setting of the water guide platform 200 can serve as a reference for the casting of the shell 100, wherein the opposite surface where the water guide platform 200 is connected to the pipe 300 can be used as a reference surface of the casting mold to ensure that the pipe 300 is placed accurately without deviation.

[0036] In some embodiments, reference Figure 2 and Figure 5 The rust-proof water cooling jacket also includes a first support rod 400, which is arranged between the two water guide platforms 200, and the two ends of the first support rod 400 along the length direction are respectively welded to the two water guide platforms 200 to fix the distance between the two water guide platforms 200, thereby preventing the two water guide platforms 200 from being offset during the casting process of the shell 100.

[0037] It is understandable that the length of the first support rod 400 is determined according to the position of the water guide port 140 of the housing 100 , and the position of the water guide port 140 of the housing 100 is determined according to the actual water inlet and outlet positions.

[0038] In some embodiments, the pipe 300 is spirally formed into multiple sections of parallel pipe bodies, and gaps exist between adjacent pipe bodies, i.e., the two adjacent pipe bodies do not contact each other. After the shell 100 is cast, the aluminum alloy material forming the shell 100 can fill the gaps between the two adjacent pipe bodies, thereby further improving the cooling and heat dissipation effect of the rust-proof water cooling jacket.

[0039] In some embodiments, referring to Figure 2 and Figure 5 , the rust-proof water cooling jacket further comprises a second support rod 500, which is arranged parallel to the first support rod 400 and is arranged on the side of the pipe 300. The second support rod 500 is welded to the side of the pipe body in contact therewith, so that the spacing between the pipe bodies remains stable and further avoids the pipe 300 from being skewed during the casting process of the shell 100.

[0040] In some embodiments, multiple second support rods 500 are arranged on the side of the pipe 300, thereby fixing multiple positions of the peripheral wall of the pipe 300 and further avoiding the pipe 300 from being skewed.

The pipe 300 is made of 06Cr19Ni10 stainless steel, which has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. During processing, burrs need to be removed from the processing surface, and the welding portions of the first support rod 400 and the second support rod 500 and the pipe 300 need to be polished flat to avoid air leakage.
