Description

Technical Field

[0001] This utility model relates to the field of turbine vacuum pump technology, and in particular to a cooling mechanism for a turbine vacuum pump. Background Technology

[0002] During operation, turbine vacuum pumps generate a significant amount of heat due to gas compression and high-speed flow. If this heat cannot be dissipated promptly, the pump body temperature will rise, affecting pump performance and lifespan. The cooling system of a turbine vacuum pump is a crucial component in ensuring the pump body maintains a suitable temperature during efficient operation. These cooling systems vary in design and implementation, but their primary goal is to reduce the heat generated inside the pump body due to gas compression and friction, thereby maintaining pump stability and extending its service life.

[0003] Existing turbine vacuum pumps have a rapid temperature rise inside the motor during operation, which can lead to excessively high internal motor temperatures and affect the motor's lifespan.

[0004] An existing patent (publication number: CN218542636U) discloses a cooling device for a two-stage magnetic levitation turbine vacuum pump, which includes a magnetic levitation vacuum pump motor, an external fan isolation box fixedly installed above the magnetic levitation vacuum pump motor, a filter box fixedly installed above the external fan isolation box, an external fan installed inside the external fan isolation box, the air inlet of the external fan communicating with the filter box, and the air outlet of the external fan communicating with the interior of the magnetic levitation vacuum pump motor; it cools the magnetic levitation vacuum pump motor by using an external fan integrated with the vacuum pump on the magnetic levitation vacuum pump motor. This cooling method has a simple structural design, low cost, and is more conducive to the development of magnetic levitation vacuum pumps.

[0005] To address the aforementioned issues, existing patents have proposed solutions that utilize an external fan integrated with the vacuum pump to cool the magnetic levitation vacuum pump motor. However, the cooling effect of using a fan to blow air onto the motor is poor, as relying solely on airflow results in inadequate heat dissipation and can only cool one side of the motor. Summary of the Invention

[0006] The purpose of this invention is to provide a cooling mechanism for a turbine vacuum pump, which can cool the heat-conducting shell and indirectly dissipate heat from the drive motor, effectively reducing the overheating of the drive motor. Since the heat-conducting shell is wrapped around the outer surface of the drive motor, it can cool the drive motor from all directions, improving the heat dissipation effect and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling mechanism for a turbine vacuum pump, comprising a drive motor, wherein a heat-conducting shell is fitted on the outer surface of the drive motor, and a heat dissipation mechanism for dissipating heat from the motor is provided on the left side of the drive motor.

[0008] The heat dissipation mechanism includes a water tank located to the left of the drive motor. A delivery pump is bolted inside the water tank. The output end of the delivery pump is connected to a connector via a pipe. Several heat-absorbing tubes are installed on the side wall of the connector. The ends of the heat-absorbing tubes are connected to a delivery pipe. The ends of the delivery pipe are connected to a flow cavity located inside the heat-conducting shell. A return pipe communicating with the flow cavity is provided on the outer surface of the heat-conducting shell. The return pipe is connected to the water tank. A cooling mechanism for cooling the coolant is installed inside the connector.

[0009] Preferably, the cooling mechanism includes a water impeller, which is installed inside the connector, and a transmission rod is fixed to the side wall of the water impeller and rotatably connected to the inner wall of the connector via a bearing.

[0010] Preferably, a fan wheel is fixed to the end of the transmission rod, and a plurality of through holes corresponding to the heat absorption tube are opened on the outer surface of the connector.

[0011] Preferably, a fixing base is disposed on the lower surface of the heat-conducting shell, and a fixing screw that is threadedly connected to the fixing base is fixed on the outer wall of the heat-conducting shell.

[0012] Preferably, the outer wall of the fixed base is fixed with two sets of fixing blocks.

[0013] Preferably, both sets of fixing blocks are equipped with fixing bolts inside.

[0014] Preferably, the power output shaft of the drive motor is connected to a pump body, and the outer wall of the pump body is connected to an air supply pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The heat dissipation mechanism can cool the heat-conducting shell and indirectly dissipate heat from the drive motor, which can effectively reduce the overheating of the drive motor. Since the heat-conducting shell is wrapped around the outer surface of the drive motor, it can cool the drive motor from all directions and improve the heat dissipation effect.

[0017] 2. Through the cooling mechanism, the water flow drives the water impeller to rotate, which in turn causes the transmission rod to drive the fan to rotate. The water flows through the through hole into multiple heat absorption tubes, which absorb heat from the water. The fan rotation generates wind power to dissipate heat from the heat absorption tubes, thereby cooling the coolant and ensuring the circulation effect of the coolant. Attached Figure Description

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A cooling mechanism for a turbine vacuum pump includes a drive motor 1, a heat-conducting shell 2 covering the outer surface of the drive motor 1, and a heat dissipation mechanism for dissipating heat from the motor on the left side of the drive motor 1.

[0028] The heat dissipation mechanism includes a water tank 3, which is located to the left of the drive motor 1. A delivery pump 31 is fixed inside the water tank 3 by bolts. The output end of the delivery pump 31 is connected to a connector 32 via a pipe. Several heat absorption pipes 33 are installed on the side wall of the connector 32. The end of the heat absorption pipes 33 is connected to a delivery pipe 34. The end of the delivery pipe 34 is connected to a flow cavity 35 opened inside the heat-conducting shell 2. The outer surface of the heat-conducting shell 2 is provided with a return pipe 36 that communicates with the flow cavity 35. The return pipe 36 is connected to the water tank 3. A cooling mechanism for cooling the coolant is installed inside the connector 32. The cooling mechanism includes a water impeller 4, which is located inside the connector 32. A transmission rod 41 is fixed to the side wall of the water impeller 4 and rotatably connected to the inner wall of the connector 32 via a bearing. A fan wheel 42 is fixed to the end of the transmission rod 41. Several through holes 43 corresponding to the heat absorption pipes 33 are opened on the outer surface of the connector 32.

[0029] By adopting the above technical solution, the heat generated by the drive motor 1 during operation is directly absorbed by the heat-conducting shell 2. At this time, the delivery pump 31 installed in the water tank 3 draws out the coolant, which is then delivered to the connector 32, flows through the heat absorption pipe 33 into the delivery pipe 34, and then enters the flow chamber 35, thereby cooling the heat-conducting shell 2 and indirectly dissipating heat from the drive motor 1. This effectively reduces the overheating of the drive motor 1. Since the heat-conducting shell 2 wraps around the outer surface of the drive motor 1, it can cool the drive motor 1 from all directions, improving the heat dissipation effect. The coolant continuously flowing into the flow chamber 35, under the action of the return pipe 36, allows the coolant carrying heat to re-enter the water tank 3 for recycling. When the coolant is circulating, the water flow pushes the water impeller 4 to rotate when it is transported to the connector 32, which in turn causes the transmission rod 41 to drive the fan wheel 42 to rotate. The water flows through the through hole 43 into multiple heat absorption tubes 33, where the heat absorption tubes 33 absorb heat from the water. The rotation of the fan wheel 42 generates wind power to dissipate heat from the heat absorption tubes 33, thereby cooling the coolant and ensuring the circulation effect of the coolant.

[0030] Specifically, such as Figures 1-2 As shown, a fixed base 5 is installed on the lower surface of the heat-conducting shell 2. A fixing screw 6 that is threadedly connected to the fixed base 5 is fixed on the outer wall of the heat-conducting shell 2. Two sets of fixing blocks 7 are fixed on the outer wall of the fixed base 5. Fixing bolts 8 are installed inside the two sets of fixing blocks 7. The power output shaft of the drive motor 1 is connected to the pump body 9. The outer wall of the pump body 9 is connected to the air supply pipe 10.

[0031] By adopting the above technical solution, the fixed base 5 is installed in a suitable position, and the fixed base 5 is fixed by the fixing bolts 8 on the fixing block 7. Then, the heat-conducting shell 2 is fixed to the fixed base 5 by the fixing screws 6, thereby ensuring the stability of the mechanism. In use, the drive motor 1 drives the vacuuming mechanism in the pump body 9 to run, and then the load equipment is vacuumed through the gas delivery pipe 10.

[0032] Working principle: The heat-conducting outer shell 2 is fixed to the fixed base 5 using fixing screws 6, thus ensuring the stability of the mechanism. The drive motor 1 drives the vacuum mechanism inside the pump body 9, which then performs a vacuum operation on the load equipment through the gas delivery pipe 10. The heat generated by the drive motor 1 during operation is directly absorbed by the heat-conducting outer shell 2. The delivery pump 31 extracts the coolant, which is delivered to the connector 32 and enters the flow chamber 35, thereby cooling the heat-conducting outer shell 2 and indirectly dissipating heat from the drive motor 1. This effectively reduces the overheating of the drive motor 1. The outer surface of the coolant can be cooled in all directions by the coolant flowing into the flow chamber 35. Under the action of the return pipe 36, the coolant carrying heat can re-enter the water tank 3 for recycling. When the coolant is circulated, the water flow will drive the water impeller 4 to rotate when it is transported to the connector 32, which will cause the transmission rod 41 to drive the fan wheel 42 to rotate. The water flow enters multiple heat absorption pipes 33 through the through hole 43. The heat absorption pipes 33 absorb the heat in the water. The fan wheel 42 rotates to generate wind power to dissipate heat from the heat absorption pipes 33, thereby cooling the coolant.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
