Cooling structure for rust prevention of motor casing

Abstract

The utility model relates to a cooling structure for rust prevention of a motor casing. The cooling structure comprises the motor casing. When the motor works, a large amount of heat is generated, cooling liquid enters the S-shaped channel through the liquid inlet pipe and penetrates through the S-shaped channel to enter the liquid outlet pipe, so that the cooling liquid takes away a large amount of heat when penetrating through the S-shaped channel, and the effect of cooling the motor shell is further achieved; the anti-corrosion layer can effectively prevent a corrosive medium in the environment from being in direct contact with the inner wall of the motor shell, so that the occurrence of corrosion is slowed down or prevented. By reducing corrosion, the service life of the motor shell can be remarkably prolonged by the anti-corrosion layer, and the replacement and maintenance cost caused by corrosion is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of motor casings, in particular to a cooling structure for preventing a motor casing from rusting. Background Art

[0002] In the prior art, opening channels in the motor casing is an important part of motor design. These channels are mainly used for cooling, heat dissipation, and possible fluid transmission. Among them, when the motor casing is cooled by coolant, there is a risk of corrosion of the casing. This is mainly because certain components in the coolant may chemically react with the motor casing material, leading to the occurrence of corrosion. Coolant usually contains a variety of additives such as water, ethylene glycol, and corrosion inhibitors. Among them, ethylene glycol is widely used in coolants due to its excellent freezing point lowering effect. However, ethylene glycol will oxidize under high-temperature heat load operating conditions. The aeration of the cooling system and the use of a large number of copper and copper alloy components will promote the oxidation of ethylene glycol to generate a mixed acid with corrosive effects mainly composed of formic acid. The mixed acid will accelerate the rusting of the metal motor casing. Utility Model Content

[0003] The main purpose of the utility model is to provide a cooling structure for preventing rust of a motor casing, so as to solve the problem that ethylene glycol in the existing motor casing will oxidize under high-temperature heat load operation conditions, and the aeration of the cooling system and the use of a large number of copper and copper alloy components will promote the oxidation of ethylene glycol to generate a mixed acid with corrosive effect mainly composed of formic acid, and the mixed acid will accelerate the rust of the metal motor casing.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a cooling structure for preventing rust of a motor casing, comprising a motor casing;

[0005] A serpentine channel is provided on the inner circumference of the motor housing, and a partition is fixedly provided on the serpentine channel to divide the serpentine channel. One side of the partition forms the head end of the serpentine channel, and the other side forms the tail end of the serpentine channel.

[0006] The head end of the serpentine channel is connected to the liquid inlet pipe, and the tail end of the serpentine channel is connected to the liquid outlet pipe;

[0007] The serpentine channel and partitions are coated with an anti-corrosion layer.

[0008] A preferred solution is that a wire take-up housing is fixedly provided on the annular wall of the motor housing, and a wire outlet hole is provided in the wire take-up housing.

[0009] A preferred solution is that the anti-corrosion layer adopts polyurethane anti-corrosion coating.

[0014] A preferred solution is that the metal tube is made of copper.

[0015] The beneficial effects of the above scheme are:

[0016] When the motor is operating, it generates a significant amount of heat.

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0025] like Figures 1-4 As shown, this embodiment provides a cooling structure for preventing a motor housing from rusting, comprising a motor housing 1. A wire take-up housing 6 is fixedly provided on the annular wall of the motor housing 1, and a wire outlet hole 7 is provided on the wire take-up housing 6.

[0026] like Figure 2 As shown, a serpentine channel 2 is opened on the inner circumference of the motor housing 1, and a partition 3 is fixedly arranged on the serpentine channel 2. The partition 3 divides the serpentine channel 2. One side of the partition 3 forms the head end of the serpentine channel 2, and the other side of the partition 3 forms the tail end of the serpentine channel 2. The head end of the serpentine channel 2 is connected to the liquid inlet pipe 4, and the tail end of the serpentine channel 2 is connected to the liquid outlet pipe 5. The serpentine channel 2 and the partition 3 are coated with an anti-corrosion layer (not shown). The anti-corrosion layer adopts polyurethane anti-corrosion coating. Among them, the motor housing 1 is formed by casting, and the serpentine channel 2 can be opened on the inner circumference of the motor housing 1 by casting. This process can indeed realize the opening of a serpentine channel on the inner circumference of the motor housing. When designing the mold, the shape and position of the serpentine channel can be reserved. When the metal liquid is poured into the mold and cooled, these channels will naturally form.

[0027] When the motor is operating, it generates a significant amount of heat. Coolant enters serpentine channel 2 through inlet pipe 4, then flows through serpentine channel 2 into outlet pipe 5. This removes a significant amount of heat as the coolant passes through serpentine channel 2, thereby cooling the motor housing. The anti-corrosion coating applied to serpentine channel 2 and baffle 3 effectively prevents corrosive media from coming into direct contact with the inner wall of the motor housing, thereby slowing or preventing corrosion. By reducing corrosion, the anti-corrosion coating significantly extends the life of the motor housing and reduces replacement and repair costs associated with corrosion.

[0028] like Figure 3 、 Figure 4 As shown, a straight groove 8 is further provided in the motor housing 1, which is not connected to the serpentine channel 2 and is sleeved in the serpentine channel 2. Figure 1As shown, the motor housing 1 has two perforations 9 formed in the annular wall, which communicate with the straight groove 8. A metal tube 10 is spirally wound within the straight groove 8. The two ends of the metal tube 10 extend through the perforations 9 and communicate with the liquid inlet pipe 4 and the liquid outlet pipe 5, respectively. The metal tube 10 is made of copper. Coolant enters the metal tube 10 through the liquid inlet pipe 4 and then passes through the metal tube 10 into the liquid outlet pipe 5. The spirally wound metal tube 10 within the straight groove 8 removes a significant amount of heat, thereby cooling the motor housing.

[0029] Further explanation, one end of the metal tube 10 is connected to the liquid inlet pipe 4 through a three-way pipe joint, and the other end is connected to the liquid outlet pipe 5 through another three-way pipe joint. The three-way pipe joint is a prior art and will not be described in detail.

[0030] The liquid in the liquid inlet pipe flows in two ways: one through the serpentine channel and the other through the metal pipe. This two-way setting greatly improves the cooling effect of the motor casing.

[0031] A pump body (not shown) is arranged along the liquid inlet pipe 4 , the liquid inlet pipe 4 is connected to a liquid storage tank (not shown), and one end of the liquid outlet pipe 5 is connected to the liquid storage tank.

[0032] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
