Description

Technical Field

[0001] This invention relates to the field of vacuum pump technology, specifically to a vacuum pump heat dissipation device. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and create a vacuum. Commonly used vacuum pumps include dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, Roots pumps, and diffusion pumps. These pumps are essential main pumps in the application of vacuum technology in various sectors of my country's national economy. Vacuum pumps generate a lot of heat during use, but current vacuum pumps only use simple heat dissipation holes for natural heat dissipation, which has low heat dissipation efficiency. Although some vacuum pumps use exhaust fans to blow air into the motor housing for heat dissipation, exhaust fans can only blow air in one direction, making it difficult to dissipate heat from the pump body located in the leeward part in time, resulting in untimely heat dissipation and easily affecting the service life of the vacuum pump. Therefore, we propose a vacuum pump heat dissipation device to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vacuum pump cooling device, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A vacuum pump cooling device includes a housing, inside which a pump body is installed. Both sides of the housing are connected and fixed with side panels, and fans are fixed inside each side panel. A filter plate is tightly fitted to one side wall of each side panel, and each filter plate has two locking holes. Each side panel is equipped with a limiting component for engaging the locking holes. An air collecting hood is fixed to the inner wall of the housing on one side of one side panel. A U-shaped air supply pipe is connected and fixed to one side wall of the air collecting hood. Four semiconductor cooling chips are fixed inside the U-shaped air supply pipe. Air blowing plates are fixed to both inner walls of the housing. The two ends of the U-shaped air supply pipe are respectively connected and fixed to the corresponding air blowing plates. A cover plate is hinged to the top of the housing.

[0008] Furthermore, the limiting assembly includes a rotating shaft rotatably connected to the top of the enclosure via a bearing. A gear is fixed to the surface of the rotating shaft. Two guide rails are fixed to the top of the enclosure. A rack is slidably connected inside a groove opened on one side wall of each guide rail. The rack is meshed with the gear. A locking plate adapted to a locking hole is fixed to one side wall of each rack. The locking plate is respectively locked inside the corresponding locking hole. A spring is fixed to one side wall of each guide rail. The other end of the spring is respectively fixedly connected to the corresponding rack.

[0009] Furthermore, both enclosures have a moisture-proof layer inside.

[0010] Furthermore, a square sealing gasket is fixed to one side wall of each of the two enclosures, and the other side of the square sealing gasket is tightly fitted to one side wall of the corresponding filter plate.

[0011] Furthermore, each of the four bottom corners of the housing is fixed with a universal self-locking wheel.

[0012] (III) Beneficial Effects

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, an embodiment of the present invention discloses a vacuum pump cooling device, including a housing 1. Universal self-locking wheels 15 are fixed to the four corners of the bottom of the housing 1, making it easier to move the vacuum pump within a short distance. A pump body 2 is installed inside the housing 1. Surrounding plates 3 are fixed to both the left and right sides of the housing 1. A moisture-proof layer 13 is provided inside each of the two surrounding plates 3. The moisture-proof layer 13 is made of a mixture of absorbent cotton and lime, which prevents humid air from entering the housing 1, thus protecting the pump body 2. A fan 4 is fixed inside each of the surrounding plates 3. A filter plate 5 is tightly fitted to one side wall of each surrounding plate 3. Two locking holes 6 are provided on each filter plate 5. A limiting component 7 for engaging the locking holes 6 is provided on each surrounding plate 3. An air collecting hood 8 is fixed to the inner wall of the housing 1 on one side of one of the surrounding plates 3. A U-shaped air supply pipe 9 is fixed to one side wall of the air collecting hood 8. Four semiconductor cooling chips 1 are fixed inside the U-shaped air supply pipe 9. 0. Both sides of the inner wall of the housing 1 are fixed with air blowing plates 11. The two ends of the U-shaped air supply pipe 9 are respectively connected and fixed to the corresponding air blowing plates 11. The top of the housing 1 is hinged with a cover plate 12. When using this vacuum pump, when the vacuum pump generates heat, the two fans 4 start. One of the fans 4 will send the outside air through the air collection hood 8 to the inside of the U-shaped air supply pipe 9. Under the action of the semiconductor cooling chip 10, the air entering the inside can be cooled. Then the cooled air will be evenly blown to the surface of the pump body 2 through the air blowing plate 11 to cool it down. Then the other fan 4 will exhaust the air used inside the housing 1. With the cooperation of the two fans 4, the inside of the housing 1 can be quickly ventilated, thus realizing the rapid cooling operation of the inside of the housing 1. The two L-shaped pipes connected to the pump body 2 in the figure slide through the housing 1 and extend to the outside, which makes it easy to remove the pump body 2 from the inside of the housing 1.

[0025] like Figure 1 and Figure 4As shown, in some embodiments, the limiting component 7 includes a rotating shaft 701 rotatably connected to the top of the enclosure 3 via a bearing. A gear 702 is fixed to the surface of the rotating shaft 701. Two guide rails 703 are fixed to the top of the enclosure 3. A rack 704 is slidably connected inside a groove opened on one side wall of each guide rail 703. The rack 704 meshes with the gear 702. A locking plate 705 adapted to the locking hole 6 is fixed to one side wall of each rack 704. The locking plate 705 is respectively locked into the corresponding locking hole 6. A spring 706 is fixed to one side wall of each guide rail 703. The other end of the spring 706 is respectively fixedly connected to the corresponding rack 704. When needed... When cleaning the filter plate 5, the rotating shaft 701 can be rotated. When the rotating shaft 701 rotates, it will drive the gear 702 to rotate. After the gear 702 rotates, it will drive the two racks 704 to move in opposite directions. After the racks 704 move, the spring 706 will be in a stretched state, and the clamping plate 705 will also move out of the inside of the clamping hole 6. At this time, the filter plate 5 can be separated from the surrounding plate 3. When installing, repeat the above operation. After the filter plate 5 and the surrounding plate 3 are attached, release the operation on the rotating shaft 701. At this time, under the restoring force of the spring 706, the clamping plate 705 can be re-clamped into the inside of the clamping hole 6, thereby realizing the limiting and fixing of the filter plate 5.

[0026] like Figure 3 and Figure 4 As shown, in some embodiments, a square sealing gasket 14 is fixed to one side wall of each of the two enclosure plates 3, and the other side of the square sealing gasket 14 is tightly fitted to one side wall of the corresponding filter plate 5, which can further enhance the sealing performance after the enclosure plate 3 and the filter plate 5 are fitted together.

[0027] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
