Description

Technical Field

[0001] This utility model relates to the field of vacuum pump equipment technology, and in particular to a vacuum pump heat dissipation housing. Background Technology

[0002] The dry scroll vacuum pump mainly consists of a pair of scroll plates, one stationary scroll plate and one moving scroll plate, which constitute the basic pumping mechanism of the scroll oil-free vacuum pump. The scroll plate is a vortex-shaped disk structure formed by one or more involute spirals with one end connected to a plane. The relative movement of the moving and stationary scroll plates forms a crescent-shaped vacuum cavity with a constantly changing volume, allowing gas to be drawn in from the pump port and discharged from the exhaust port, completing the exhaust cycle. The vacuum pump housing can play a role in heat dissipation.

[0003] Currently, Chinese Patent Publication No. CN113431781A discloses a dry scroll vacuum pump, including a pump body assembly, an eccentric main shaft, and a scroll pumping assembly. The eccentric main shaft is located inside the pump body assembly and is rotatably connected to the pump body assembly. The pump body assembly includes a main pump body, the inner cavity of which includes an air inlet chamber and a motor chamber. An air inlet hole is provided on the side wall of the air inlet chamber. A stationary scroll plate is fixed to one end face of the main pump body. The moving spiral groove in the moving scroll plate and the stationary spiral groove in the stationary scroll plate are both connected to the air inlet chamber. One end of the eccentric main shaft is connected to the moving scroll plate, and the other end of the eccentric main shaft is fixed with a motor rotor. A motor stator is sleeved on the motor rotor and is fixedly connected to the main pump body. Both the motor rotor and the motor stator are located inside the motor chamber.

[0004] Although the vacuum pump housing has heat dissipation fins that can dissipate heat, these fins are only located on the pump body and it is difficult to form a flow channel on the housing surface, so the heat dissipation effect is limited. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a vacuum pump heat dissipation housing to solve the problem of limited heat dissipation capacity of vacuum pump housings in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a vacuum pump heat dissipation housing, including a housing, an end cover, and a flow guide shroud. The housing has a plurality of heat dissipation fins evenly distributed on its sidewalls. The end cover is in contact with each heat dissipation fin. The end cover has a plurality of heat conduction holes located between adjacent heat dissipation fins. The flow guide shroud has a flow guide plate corresponding to the heat dissipation fins.

[0007] By adopting the above technical solution, adjacent heat dissipation fins, in conjunction with two corresponding guide plates on the guide shroud, and the heat conduction holes on the end cover form a guide channel, which allows the airflow outside the shell to flow through the guide channel, further heating the shell and exchanging heat with the outside environment, thereby improving the heat dissipation effect of the shell. Moreover, the structure is simple and easy to process.

[0008] In one embodiment of the present invention, heat dissipation fins are arranged horizontally on the side wall of the housing, the heat dissipation fins are evenly distributed vertically on both sides of the housing, and the heat dissipation fins extend along the shape of the housing.

[0009] By adopting the above technical solution, the heat dissipation fins can be set to correspond to the shape of the shell and distributed on the side wall of the shell, which is easier to process. The horizontal setting makes it easier for the heat conduction holes to correspond to the heat dissipation fins.

[0010] In one embodiment of this utility model, the heat-conducting hole penetrates the end cover, and the heat-conducting hole is evenly distributed on the end cover corresponding to the heat dissipation fins. The upper end face of the heat-conducting hole is flush with the lower end of the upper heat dissipation fin, and the lower end face of the heat-conducting hole is flush with the upper end face of the lower heat dissipation fin.

[0011] By adopting the above technical solution, the heat conduction holes can be correspondingly arranged between the two heat dissipation fins, so that the airflow between the heat dissipation fins can flow out through the heat conduction holes, which can facilitate the airflow outside the shell, facilitate heat exchange, and improve heat dissipation efficiency.

[0012] In one embodiment of the present invention, the guide plate is horizontally disposed on the side wall of the guide shroud, and each guide plate corresponds to a heat dissipation fin. Each guide plate and the heat dissipation fin have the same thickness, and the upper surface of the guide plate is flush with the upper surface of the heat dissipation fin, and the lower surface of the guide plate is flush with the lower surface of the heat dissipation fin.

[0013] By adopting the above technical solution, the guide plate can be set to correspond to the heat-conducting fins, which facilitates airflow.

[0014] As described above, the vacuum pump heat dissipation housing of this utility model has the following beneficial effects: it can form a flow channel by adjacent heat dissipation fins, in conjunction with two corresponding flow guide plates on the flow guide cover, and then by heat conduction holes on the end cover. This allows the airflow outside the housing to flow through the flow guide channel, which can further heat the housing and the outside environment, thereby improving the heat dissipation effect of the housing. Moreover, the structure is simple and easy to process. Attached Figure Description

Therefore, they have no substantial technical significance.

[0021] like Figure 1 , Figure 2 As shown, this utility model provides a vacuum pump heat dissipation housing, including a housing 1, an end cover 2, and a flow guide shroud 3. Multiple heat dissipation fins 4 are evenly distributed on the side wall of the housing 1. Two adjacent heat dissipation fins 4 form a flow guide channel. The end cover 2 is in contact with each heat dissipation fin 4. The end cover 2 has heat conduction holes 5 disposed at the end of the flow guide channel. Multiple heat conduction holes 5 are provided and distributed between adjacent heat dissipation fins 4. The other end of the flow guide channel extends to the flow guide shroud 3, and the flow guide shroud 3 is provided with flow guide plates 6 distributed corresponding to the heat dissipation fins 4.

[0022] The heat conduction hole 5 penetrates the end cover 2. The heat conduction hole 5 corresponds to the heat dissipation fins 4 and is evenly distributed on the end cover 2. The upper end face of the heat conduction hole 5 is flush with the lower end of the upper heat dissipation fin 4, and the lower end face of the heat conduction hole 5 is flush with the upper end face of the lower heat dissipation fin 4. The heat conduction hole 5 penetrates the end of the flow channel.

[0023] The guide plate 6 is horizontally set on the side wall of the guide shroud 3, and each guide plate 6 corresponds to a heat dissipation fin 4. Each guide plate 6 and the heat dissipation fin 4 have the same thickness. The upper end face of the guide plate 6 is flush with the upper end face of the heat dissipation fin 4, and the lower end face of the guide plate 6 is flush with the lower end face of the heat dissipation fin 4. The guide plate 6 protrudes from the surface of the guide shroud 3 and can guide the airflow into the guide channel.

[0024] In summary, this utility model can form a flow channel by using adjacent heat dissipation fins 4, in conjunction with two corresponding flow guide plates 6 on the flow guide shroud 3, and then forming a flow guide channel by the heat conduction holes 5 on the end cover 2. This allows the external airflow of the shell 1 to flow through the flow guide channel, which can further heat the shell 1 and the external environment, thereby improving the heat dissipation effect of the shell 1. Moreover, the structure is simple and easy to process.

[0025] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
