Description

Technical Field

[0001] This utility model relates to the field of motor heat dissipation technology, and in particular to a cooling water channel shell for motor heat dissipation. Background Technology

[0002] An electric motor is an electromagnetic device that converts electrical energy into mechanical energy based on the law of electromagnetic induction. It is mainly divided into two categories: electric motors and generators. The cooling water channel shell of an electric motor is made of thermally conductive materials such as aluminum alloy. It has an internal cooling water channel structure that achieves efficient heat dissipation through circulating coolant. The water-cooled motor shell is a high-efficiency cooling external protection structure specially designed for electric motors. It effectively absorbs and dissipates the heat generated by the generator by introducing coolant into the pipes or channels inside the motor shell, ensuring that the motor maintains a suitable temperature under high load or long-term operation.

[0003] Currently, most cooling channel housings on the market lack adequate corrosion protection for their internal cooling channels after prolonged use, leading to corrosion and impacting their lifespan. Furthermore, existing cooling channel housings cannot provide secondary heat dissipation, thus affecting their overall cooling performance. Therefore, a new type of cooling channel housing for motor cooling is needed to meet these user requirements. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1: Refer to Figures 1-7This is the first embodiment of the present invention. This embodiment provides a cooling water channel shell for motor heat dissipation. It can solve the problem that most cooling water channel shells on the market do not have good anti-corrosion effect after long-term use, resulting in corrosion of the cooling water channel and affecting its service life. At the same time, existing cooling water channel shells cannot perform secondary heat dissipation, thus affecting the heat dissipation effect of the cooling water channel shell. It includes a cooling shell body 1, with water channel through holes 101 at the top of the cooling shell body 1, and a first rectangular groove 102 on the outer wall of the cooling shell body 1. The top and bottom of the first rectangular groove 102 are provided with mounting grooves 1021. A heat dissipation mechanism 2 is provided inside the first rectangular groove 102. A water inlet cooling pipe 3 and a water outlet cooling pipe 4 are respectively installed on the outer wall of the cooling shell body 1. Cooling water channel grooves 5 are provided inside the water channel through holes 101.

[0023] Combination Figure 2 , Figure 6 and Figure 7 In this embodiment of the present invention, the cooling water channel 5 is arranged in a meandering shape and installed inside the water channel through hole 101. The two ends of the cooling water channel 5 are respectively connected to the inlet cooling pipe 3 and the outlet cooling pipe 4. The cooling water channel 5 includes an anti-corrosion layer 501, a first base layer 502 and a second base layer 503. The bottom end of the anti-corrosion layer 501 is provided with the first base layer 502, and the bottom end of the first base layer 502 is provided with the second base layer 503. The outer wall of the anti-corrosion layer 501 is sprayed with a high-density polyethylene coating. The first base layer 502 and the second base layer 503 are made of stainless steel.

[0024] The specific working principle is as follows: First, the cooling water channel 5 is installed inside the water channel through hole 101 in a meandering shape, and the cooling water channel 5 penetrates multiple sets of water channel through holes 101. At the same time, the outer wall of the anti-corrosion layer 501 is sprayed with a high-density polyethylene coating, which makes the cooling water channel 5 have good corrosion resistance and high temperature resistance, and can withstand large circumferential stress and longitudinal shrinkage rate. Furthermore, the first base layer 502 and the second base layer 503 are made of stainless steel, which gives the cooling water channel 5 excellent corrosion resistance and high temperature resistance, thereby extending the service life of the cooling water channel 5.

[0025] Example 2: Refer to Figures 1-7This is the first embodiment of the present invention. This embodiment provides a cooling water channel shell for motor heat dissipation. It can solve the problem that most cooling water channel shells on the market do not have good anti-corrosion effect after long-term use, resulting in corrosion of the cooling water channel and affecting its service life. At the same time, the existing cooling water channel shells cannot perform secondary heat dissipation, thus affecting the heat dissipation effect of the cooling water channel shell. The heat dissipation mechanism 2 includes a fixed frame 201, which is disposed inside the first rectangular groove 102. The fixed frame 201 has a second rectangular groove 202 inside. The top and bottom of the fixed frame 201 have a first through hole 203 communicating with the second rectangular groove 202. Heat dissipation fins 209 are fixedly installed on one side wall of the fixed frame 201.

[0026] Combination Figure 2 , Figure 3 and Figure 5 In this embodiment of the present invention, the sidewalls at both ends of the second rectangular groove 202 are provided with sliding grooves 204, and a slider 205 is provided inside the sliding groove 204. A mounting plate 206 passing through the first through hole 203 is installed at the end of the slider 205 away from the sliding groove 204, and a push plate body 207 is installed on the sidewall of the mounting plate 206. Elastic components 208 are installed on the inner wall of the second rectangular groove 202, and the top end of the elastic component 208 is fixedly connected to the bottom end of the mounting plate 206. The elastic component 208 includes a fixing... Sleeve 2081 is fixedly installed on the side wall of the second rectangular groove 202. A sliding rod 2082 is slidably arranged inside the fixed sleeve 2081, and a piston rod 2083 is installed at one end of the sliding rod 2082 inside the fixed sleeve 2081. The outer wall of the piston rod 2083 cooperates with the fixed sleeve 2081. A high-pressure spring body 2084 is installed at the top of the fixed sleeve 2081, and the bottom end of the high-pressure spring body 2084 is fixedly connected to the top end of the piston rod 2083.

[0027] The specific working principle is as follows: when the heat dissipation mechanism 2 needs to be installed and disassembled, the fixed frame 201 first cooperates with the first rectangular groove 102, and the mounting plate 206 engages with the mounting groove 1021. The slider 205 and the sliding groove 204 also cooperate. Simultaneously, pressing the two sets of push plate bodies 207 causes the mounting plate 206 to slide through the slider 205 and the sliding groove 204, thus squeezing the elastic component 208 inside the first through hole 203. At the same time, when the elastic component 208 is squeezed, the sliding rod 2082 is squeezed, causing the piston rod 2083 to move within the fixed sleeve 20. The internal sliding and compression of the high-pressure spring body 2084 causes deformation, allowing the mounting plate 206 to enter the interior of the first through hole 203. Simultaneously, the fixing frame 201 is inserted into the interior of the first rectangular groove 102. The high-pressure spring body 2084 elastically recovers, causing the mounting plate 206 to engage with the mounting groove 1021, thereby installing the fixing frame 201. This facilitates the contact of the heat dissipation fins 209 with the outer wall of the cooling shell body 1, allowing the heat dissipation fins 209 to provide secondary heat dissipation for the cooling shell body 1, thus improving the cooling effect.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
