[0036] To solve the problem of poor reliability of the cooling fan set in the electronic control cavity of the magnetic levitation compressor, the present utility model proposes a magnetic levitation compressor. A phase change heat dissipation device is provided inside the electronic control cavity of the magnetic levitation compressor. The heat absorption heat exchanger provided in the electronic control cavity is used to cool the components arranged in the electronic control cavity, and the heat is transferred through the refrigerant pipeline to the heat dissipation heat exchanger arranged in the electronic control cavity to dissipate the heat of the components in the electronic control assembly. Compared with the cooling fan, the phase change heat dissipation device has higher durability and stability, improving the overall reliability of the magnetic levitation compressor.

[0037] According to an embodiment of the present utility model, a magnetic levitation compressor 100 is proposed. Please refer to Figure 1 , Figure 2 and Figure 3 As shown, the magnetic levitation compressor 100 includes a housing assembly 10, a phase change heat dissipation device 20, and an electronic control assembly 30.

[0038] The housing assembly 10 includes a body 11 and a cover 12. The body 11 is an integrally cast housing made of metal material, and its material can be metal materials such as aluminum alloy. The cover 12 is buckled on the body 11, and an electronic control cavity 13 is defined between the cover 12 and the body 11. The phase change heat dissipation device 20 and the electronic control assembly 30 are both arranged in the electronic control cavity 13.

[0039] The electronic control assembly 30 includes an AC / DC power conversion device (not shown in the figure), an electromagnetic bearing control device (not shown in the figure), a soft start control device (not shown in the figure), etc. The electronic control assembly 30 is used to supply power to devices such as the magnetic levitation bearing in the magnetic levitation compressor 100 and control its operation.

[0040] The phase change heat dissipation device 20 includes a heat absorption heat exchanger 21, a refrigerant pipeline 22, and a heat dissipation heat exchanger 23. The heat absorption heat exchanger 21 is in a plate-like structure, and a medium flow channel can be formed inside the heat absorption heat exchanger 21. The phase change medium in the refrigerant pipeline 22 can flow into the medium flow channel to absorb latent heat through phase change. At least part of the components in the electronic control assembly 30 are installed on the heat absorption heat exchanger 21 and are thermally connected to the heat absorption heat exchanger 21. The heat generated by the components during operation can be conducted to the phase change medium through the heat absorption heat exchanger 21, and the phase change medium flows through the refrigerant pipeline 22 to the heat dissipation heat exchanger 23 for heat dissipation, thereby transferring the heat generated by the components.

[0041] Since the phase change heat dissipation device 20 uses a flowing phase change medium as the heat dissipation medium, compared with the traditional cooling fan for heat dissipation, the heat dissipation capacity can be significantly improved, and it has higher durability and stability. In this embodiment, the heat absorption heat exchanger 21, the refrigerant pipeline 22, and the heat dissipation heat exchanger 23 together constitute the internal circulation path of the phase change medium, and the phase change medium can realize the cycle of heat absorption and heat dissipation during the circulation process.

[0042] In some embodiments, as Figure 3 shown, the heat dissipation heat exchanger 23 is arranged closer to the edge of the electronic control cavity than the heat absorption heat exchanger 21, so as to disperse the heat concentrated in the central area of the electronic control cavity 13 to the edge area of the electronic control cavity 13, realizing the heat dissipation of the electronic control cavity 13.

[0043] In other embodiments, the heat absorption heat exchanger 21 is arranged in the electronic control cavity 13, and at least part of the heat dissipation heat exchanger 23 is arranged outside the electronic control cavity 13, so as to disperse the heat collected in the electronic control cavity 13 to the outside of the electronic control cavity 13, realizing the heat dissipation of the electronic control cavity 13.

[0044] In this embodiment, the heat dissipation heat exchanger 23 is a fin radiator. The fin radiator has a compact design, occupies less space, has a large unit heat exchange area, and improves the heat exchange efficiency.

[0045] According to the magnetic levitation compressor 100 of the present utility model, the phase change heat dissipation device 20 is used to replace the heat dissipation fan. On the one hand, the heat dissipation effect of the electronic components in the electronic control cavity 13 is improved. On the other hand, compared with the heat dissipation fan, the phase change heat dissipation device 20 has higher durability and stability, improving the overall reliability of the magnetic levitation compressor 100.

[0046] In some embodiments of the present utility model, please refer to Figure 1 and Figure 3 shown, the two ends of the magnetic levitation compressor 100 along the first direction are respectively an air inlet end 101 and an air outlet end 102. The air inlet end 101 of the magnetic levitation compressor 100 refers to the end where the low-temperature and low-pressure refrigerant flows in. The low-temperature and low-pressure refrigerant is pressurized in the compression cavity (not shown in the figure) of the magnetic levitation compressor 100, and the pressurized refrigerant is discharged from the air outlet end 102. In the direction from the air inlet end 101 to the air outlet end 102, the electronic control cavity 13 includes a first installation area 131 and a second installation area 132 arranged in sequence. The first installation area 131 is arranged closer to the air inlet end 101 than the second installation area 132. During the pressurization process of the refrigerant in the magnetic levitation compressor 100, it changes from the low-temperature and low-pressure state at the air inlet end 101 to the high-temperature and high-pressure state at the air outlet end 102. The temperature of the refrigerant at the air inlet end 101 must be lower than the temperature at the air outlet end 102. Therefore, affected by the temperature of the refrigerant, the temperature of the first installation area 131 is lower than the temperature of the second installation area 132. The electronic control component 30 includes a first part of components 31 and a second part of components 32. The heat generation amount of the first part of components 31 is greater than the heat generation amount of the second part of components 32, and the first part of components 31 is arranged in the first installation area 131, and the second part of components 32 is arranged in the second installation area 132. In this embodiment, arranging the first part of components 31 with a higher heat generation amount in the first installation area 131 with a lower temperature is beneficial to the heat dissipation of the first part of components 31 and improves the stability of its operation.

[0047] Understandably, due to the differences in structure and power among different components in the electronic control assembly 30, there are also differences in their heat generation. By arranging the components with larger heat generation in the first installation area 131, the cold source at the air inlet end 101 of the magnetic levitation compressor 100 is used to dissipate heat from the first part of the components 31 with larger heat generation, and the components with smaller heat generation are arranged in the second installation area 132, so as to optimize the temperature of each component in the electronic control cavity 13.

[0048] Furthermore, the heat dissipation heat exchanger 23 is arranged in the first installation area 131, and the cold source at the air inlet end 101 of the magnetic levitation compressor 100 is used to accelerate the heat dissipation rate of the heat dissipation heat exchanger 23.

[0049] In some embodiments of the present invention, please refer to Figure 1 、 Figure 3 and Figure 4 As shown, the electronic control assembly 30 includes an IGBT module 311 and a capacitor 33. The IGBT module 311 is installed on the heat absorption heat exchanger 21 and is thermally connected thereto to dissipate heat from the IGBT module 311. Along the second direction, the heat dissipation heat exchanger 23 and the capacitor 33 are respectively located on both sides of the IGBT module 311. Among electronic components, since both the IGBT module 311 and the capacitor 33 are electronic components with larger heat generation, therefore, the capacitor 33 also needs to have good heat dissipation. The capacitor 33 and the heat dissipation heat exchanger 23 are respectively arranged on both sides of the IGBT module 311 to reduce the mutual influence during heat dissipation between the heat dissipation heat exchanger 23 and the capacitor 33. Wherein, the second direction is perpendicular to the first direction.

[0050] In some embodiments of the present invention, please refer to Figure 3 、 Figure 4 and Figure 5 As shown, the electronic control assembly 30 further includes a busbar 34 and a first heat conducting gasket 35. The busbar 34 can be a copper bar or an aluminum bar, and its function is to collect, distribute and transmit electric energy to supply power to other electronic components in the electronic control assembly 30. The busbar 34 is electrically connected to the IGBT module 311 and the capacitor 33 respectively.

[0051] The first heat conducting gasket 35 is a sheet made of a material with good heat conductivity. The first heat conducting gasket 35 includes but is not limited to sheet-like objects in the form of metal plates, epoxy heat conducting sheets, heat conducting plastics, heat conducting rubbers, heat conducting silica gel gaskets, etc. The first heat conducting gasket 35 is arranged between the busbar 34 and the heat absorption heat exchanger 21. The air gap between the busbar 34 and the heat absorption heat exchanger 21 is filled by the first heat conducting gasket 35, and the flexible and elastic characteristics of the first heat conducting gasket 35 are used to enable it to cover the uneven surfaces of the heat absorption heat exchanger 21 and the busbar 34. The heat on the busbar 34 is transferred to the heat absorption heat exchanger 21 through the first heat conducting gasket 35, thereby improving the efficiency and service life of the busbar 34.

[0052] Furthermore, please combine Figure 3 , Figure 4 and Figure 5 As shown, the busbar 34 includes a first connection portion 341 and a second connection portion 342 connected to each other, the first connection portion 341 is electrically connected to the IGBT module 311, the second connection portion 342 is electrically connected to the capacitor 33, and the first connection portion 341 is located in the second installation area 132. Compared with the IGBT module 311, the heat generated by the busbar 34 is less than that of the IGBT module 311, therefore, the first connection portion 341 is arranged in the second installation area 132, so that the IGBT module 311 is as close as possible to the air intake end 101 of the magnetic levitation compressor 100, and the heat dissipation layout of the electronic control component 30 is optimized.

[0053] In some embodiments of the present invention, please combine Figure 1 , Figure 3 and Figure 6 As shown, the body 11 has a first mounting surface 121 and a second mounting surface 122. The first mounting surface 121 and the second mounting surface 122 are arranged to be spaced apart and not overlapped in a direction perpendicular to the first mounting surface 121, and the second direction is parallel to the first mounting surface 121; the heat absorption heat exchanger 21 is installed on the first mounting surface 121, the capacitor 33 is installed on the second mounting surface 122, and the IGBT module 311 is thermally connected to one end of the heat absorption heat exchanger 21 away from the first mounting surface 121. The above arrangement enables the body 11 to form two different installation spaces in a direction perpendicular to the first installation surface 121. The phase change heat sink 20 and the IGBT module 311 are installed on the first installation surface 121, and the capacitor 33 is installed on the second installation surface 122. This can reduce the height difference between the IGBT module 311 and the top of the capacitor 33 in the direction perpendicular to the first installation surface 121, so that the connection position of the IGBT module 311 and the busbar 34 is kept as flush as possible with the positive / negative terminals on the top of the capacitor 33. On the premise of reducing the bending deformation of the busbar 34, they are electrically connected to the IGBT module 311 and the capacitor 33 respectively, and the overall structure of the capacitor 33 and the IGBT module 311 is compact and easy to install.

[0054] Furthermore, please combine Figure 1 Figure 4 and Figure 6As shown, the busbar 34 is located at one end of the capacitor 33 facing away from the second mounting surface 122. The electronic control assembly 30 further includes a busbar 34 and a second heat-conducting gasket 36. The second heat-conducting gasket 36 is disposed between the capacitor 33 and the second mounting surface 122, and the second heat-conducting gasket 36 is thermally connected to the capacitor 33 and the second mounting surface 122 respectively. A second heat-conducting gasket 36 is provided between the bottom of the capacitor 33 and the body 11, and the bottom of the capacitor 33 is thermally connected to the body 11 through the second heat-conducting gasket 36, so that the heat generated by the capacitor 33 is transferred to the body 11 through the second heat-conducting gasket 36, which is beneficial to the heat dissipation of the capacitor 33. It should also be noted that in this embodiment, the heat on the capacitor 33 is conducted to the second mounting surface 122 of the body 11 for heat dissipation, while the heat on the IGBT module 311 is conducted to the heat dissipation heat exchanger 23 for heat dissipation. Along the second direction, the second mounting surface 122 and the heat dissipation heat exchanger 23 are located on both sides of the IGBT module 311 respectively, and along the direction perpendicular to the first mounting surface 121, there is a gap between the second mounting surface 122 and the heat dissipation heat exchanger 23. The heat dissipation heat exchanger 23 and the second mounting surface 122 of the heat dissipation base are arranged in two relatively distant spaced areas, reducing the mutual influence between the second mounting surface 122 and the heat dissipation heat exchanger 23 during the heat dissipation process.

[0055] In this embodiment, please refer to Figure 1 and Figure 4 As shown, the first part of the components 31 includes an IGBT module 311, and the second part of the components 32 includes a contactor 321 and a small buffer capacitor 322. The magnetic levitation compressor 100 further includes a third heat-conducting gasket 37. The contactor 321 is thermally connected to the heat absorption heat exchanger 21 through the third heat-conducting gasket 37, and the heat on the contactor 321 is transferred to the heat absorption heat exchanger 21 by using the third heat-conducting gasket 37 to dissipate heat from the contactor 321.

[0056] The magnetic levitation compressor 100 further includes an impeller (not shown in the figure) mounted on the body 11, an integrated motor rotor made of permanent magnet material and a drive shaft (not shown in the figure), electromagnetic bearings and other devices (not shown in the figure).

[0057] IGBT (Insulated Gate Bipolar Transistor) is an insulated gate bipolar transistor, which is a composite fully controlled voltage-driven power semiconductor device composed of a bipolar junction transistor (BJT) and a metal oxide semiconductor (MOS) insulated gate field effect transistor. The IGBT module 311 is a modular semiconductor product formed by bridging and packaging an IGBT (insulated gate bipolar transistor chip) and an FWD (freewheeling diode chip) through a specific circuit; the packaged IGBT module is directly applied to equipment such as frequency converters.

[0058] According to the second aspect of the present utility model, an air conditioner is further provided. The air conditioner includes the magnetic levitation compressor 100 according to any one of the first aspect. The working cycle of the refrigerant in the air conditioner provided in this embodiment is as follows: The high-temperature and high-pressure refrigerant (such as Freon, etc.) is discharged from the air conditioner compressor and enters the condenser, releasing heat to the copper tube cooling water and condensing into a medium-temperature and high-pressure refrigerant liquid. Then, it passes through the throttle valve to be depressurized into a low-temperature and low-pressure liquid and enters the evaporator, absorbing heat from the chilled water flowing through the copper tube in the evaporator housing, vaporizing into a low-temperature and low-pressure gas and then being inhaled into the magnetic levitation compressor 100. It is compressed by the impeller in the magnetic levitation compressor 100 into a high-temperature and high-pressure gas and discharged. Through this cycle, the purpose of cooling is ultimately achieved.

[0059] As described above, only the preferred specific embodiments of the present utility model are provided, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
