Description

Technical Field

[0001] This utility model relates to the technical field of motor heat dissipation equipment, and specifically to an explosion-proof motor heat dissipation end cover. Background Technology

[0002] Explosion-proof motors are a type of motor that can be used in flammable and explosive environments without producing electrical sparks during operation. They are primarily used in coal mines, oil and gas, petrochemical, and chemical industries. Additionally, they are widely used in textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, and pharmaceuticals. As a primary power source, explosion-proof motors are typically used to drive pumps, fans, compressors, and other transmission machinery.

[0003] Most existing explosion-proof motor heat dissipation end covers have tortuous water-cooling pipes installed on the inside of the end cover to dissipate heat from the inside of the explosion-proof motor. However, due to the small contact area between the water-cooling pipes and the air inside the explosion-proof motor, the heat dissipation performance of existing explosion-proof motor heat dissipation end covers is limited, which can easily lead to overheating of the motor. Therefore, it is necessary to develop an explosion-proof motor heat dissipation end cover with better heat dissipation performance. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof motor heat dissipation end cover, which solves the problem of poor heat dissipation performance of traditional explosion-proof motor heat dissipation end covers.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] like Figure 1-3As shown in the figure, the explosion-proof motor heat dissipation end cover of this embodiment includes a cover body 1; a heat dissipation mechanism, which includes heat collecting fins 4 and water cooling pipes 5. The heat collecting fins 4 are attached to the inner side of the cover body 1. The heat collecting fins 4 are used to increase the contact area between the heat dissipation mechanism and the air inside the explosion-proof motor, thereby improving the heat dissipation effect of the device. The water cooling pipes 5 are coiled around the heat collecting fins 4 to increase the contact area between the water cooling pipes 5 and the heat collecting fins 4. The heat dissipation mechanism also includes heat dissipation fins 8, which are disposed on the outer side of the cover body 1. A plurality of heat-conducting rods 10 are provided between the heat collecting fins 4 and the heat dissipation fins 8. The heat-conducting rods 10 are used to conduct the heat on the heat collecting fins 4 to the heat dissipation fins 8, so that the device can perform passive heat dissipation. A cooling fan 9 is attached to the outer side of the heat dissipation fins 8. The cooling fan 9 is used to accelerate the airflow around the heat dissipation fins 8 to further improve the heat dissipation performance of the device. The heat collecting fins 4, the heat-conducting rods 10 and the heat dissipation fins 8 are all made of copper.

[0024] One end of the water-cooling pipe 5 is provided with a water inlet 6, and the other end is provided with a water outlet 7.

[0025] The inner side of the cover 1 is provided with a sealing ring 3, which is made of fluororubber. Fluororubber has excellent heat resistance and corrosion resistance, and can adapt to the environment inside the explosion-proof motor. The periphery of the cover 1 is provided with several connecting seats 2, which are used to connect the cover 1 to the explosion-proof motor housing.

[0026] Working principle

[0027] When cooling the explosion-proof motor, firstly, the cover 1 is connected to the housing of the explosion-proof motor via the connecting seat 2. Under the action of the sealing ring 3, a sealed space is formed inside the explosion-proof motor. Then, the explosion-proof motor is started. The explosion-proof motor generates a large amount of heat during operation, and the air inside the explosion-proof motor is heated. Under the heat collection effect of the heat collecting fins 4, the heat is transferred to the heat collecting fins 4. Cold water is introduced into the water inlet 6. The cold water flows in the water cooling pipe 5 and cools the heat collecting fins 4. Under the conduction of the heat conducting rod 10, some of the heat on the heat collecting fins 4 is transferred to the heat dissipation fins 8. The cooling fan 9 is started to accelerate the air flow near the heat dissipation fins 8, thereby cooling the heat dissipation fins 8. The temperature inside the explosion-proof motor decreases, completing the cooling of the explosion-proof motor.
