Description

Technical Field

[0001] The present application belongs to the technical field of air compressors, and specifically relates to a static scroll for a scroll air compressor and a scroll air compressor. Background Art

[0002] Scroll air compressors have the advantages of low noise, low vibration and high efficiency, and are increasingly used in oil-free air compression systems. At present, oil-free scroll air compressors are often used in the field of oxygen production, which puts higher requirements on the heat dissipation of oil-free scroll air compressors.

[0003] The scroll air compressor includes a scroll assembly and a drive assembly. The scroll assembly includes a fixed scroll and a movable scroll that cooperate with each other. The fixed scroll has a front side with vortex teeth and a back side with heat dissipation fins. The drive assembly is used to drive the movable scroll to rotate, so as to generate pressurized air under the relative rotation of the movable scroll and the fixed scroll. In order to improve the wear resistance of the fixed scroll, it is usually necessary to oxidize the surface of the fixed scroll. When performing the oxidation treatment, the fixed scroll is generally connected to the prototype and immersed in the electrolyte and energized. An oxide layer is formed on the surface of the fixed scroll that contacts the electrolyte to improve the wear resistance of the fixed scroll. However, in order to ensure the oxidation treatment effect of the fixed scroll, the entire fixed scroll is usually immersed in the electrolyte. This will cause an oxide layer to form on the heat dissipation fins on the back of the fixed scroll, thereby affecting the heat conduction effect of the heat dissipation fins, and then causing the operating temperature of the fixed scroll to be higher, affecting the service life of the fixed scroll.

[0004] In order to avoid the formation of an oxide layer on the heat sink fins and ensure the life of the static vortex disc, an additional masking tool is required to mask the heat sink fins when the static vortex disc is oxidized. However, due to the complex shape of the heat sink fins, the shape of the masking tool is also complex, resulting in a high implementation cost, and the installation time cost of the masking tool is high, which in turn affects the production efficiency of the static vortex disc. Utility Model Content

[0005] The present application provides a stationary scroll for a scroll air compressor, so as to facilitate shielding the back side of the stationary scroll and improve the production efficiency of the stationary scroll.

[0006] The technical solutions adopted in this application are:

[0007] A fixed scroll for a scroll air compressor, comprising:

[0008] a fixed scroll body, the fixed scroll body having a front surface on which a volute is provided and a back surface opposite to the front surface, and the fixed scroll body having an exhaust port;

[0009] A radiator body, the radiator body being arranged on the back side of the static scroll body and being arranged separately from the static scroll body;

[0010] A heat transfer structure is arranged at the exhaust port and between the exhaust port and the radiator body to transfer heat at the exhaust port to the radiator body.

[0011] By adopting the above technical scheme, since the radiator body is arranged at the back surface of the static scroll body and is separately arranged from the static scroll body, the structure design of the back surface of the static scroll body is simplified, so that the back surface of the static scroll body can be designed as a larger plane, thereby simplifying the structure of the shielding tool, reducing the production cost of the shielding tool, and achieving the effect of facilitating the installation of the shielding tool on the back surface of the static scroll body, thereby reducing the time cost during the installation of the shielding tool, and further improving the oxidation treatment efficiency of the static scroll body, thereby improving the production efficiency of the static scroll.

[0012] In addition, since the temperature of the exhaust port increases during the operation of the scroll air compressor, the temperature of the static scroll body around the exhaust port is high, and the heat transfer structure is arranged between the exhaust port and the radiator body, so that the heat at the exhaust port is transferred to the radiator body through the heat transfer structure, thereby improving the heat dissipation effect of the exhaust port, greatly reducing the temperature of the exhaust port, and further greatly improving the heat dissipation effect of the static scroll.

[0013] Optionally, the heat transfer structure comprises a heat transfer seat arranged on the radiator body and a heat transfer rib arranged on the static scroll body, and the heat transfer rib is in contact with the heat transfer seat.

[0014] By adopting the above technical scheme, since the heat transfer rib is in contact with the heat transfer seat, the heat at the exhaust port is transferred to the heat transfer seat through the heat transfer rib, so as to transfer the heat at the exhaust port to the heat transfer seat through the heat transfer structure, thereby improving the heat dissipation effect and efficiency of the static scroll body.

[0015] Optionally, the heat transfer rib is arranged in extension along the circumference of the exhaust port and extends into the heat transfer seat, and the outer circumferential surface of the heat transfer rib is in contact with the inner circumferential surface of the heat transfer seat.

[0016] By adopting the technical scheme, since the heat transfer ribs are arranged along the circumferential direction of the exhaust port and extend into the heat transfer seat, that is, the heat transfer ribs are inserted and matched with the heat transfer seat, on the one hand, the heat transfer seat is positioned by the inserted and matched heat transfer ribs, so as to reduce the fixing difficulty of the heat sink body, improve the fixing effect of the heat sink body, on the other hand, the contact area between the heat transfer ribs and the heat transfer seat is increased, so as to greatly improve the heat transfer efficiency between the heat transfer ribs and the heat transfer seat, and further greatly improve the heat dissipation effect and the heat dissipation efficiency of the static vortex disc body. At the same time, compared with the heat transfer ribs being sleeved on the outside of the heat transfer seat, the exhaust area of the exhaust port is ensured, so as to ensure the smoothness of the exhaust.

[0017] Optionally, the diameter of the heat transfer rib gradually decreases in the direction away from the static vortex disc body, and the inner circumferential surface of the heat transfer seat is matched with the heat transfer rib.

[0018] By adopting the technical scheme, since the diameter of the heat transfer rib gradually decreases in the direction away from the static vortex disc body, on the one hand, the diameter of the heat transfer rib away from the static vortex disc is smaller than the diameter of the heat transfer rib close to the static vortex disc, so that when the heat sink body is assembled, the end of the heat transfer rib away from the static vortex disc can guide the heat sink body, so as to facilitate the assembly of the heat sink body, on the other hand, the contact area between the heat transfer rib and the heat transfer seat is further increased, so as to further improve the heat dissipation effect and the heat dissipation efficiency of the static vortex disc body.

[0019] Optionally, one of the heat transfer rib and the heat transfer seat is provided with a receiving gap, and the other is provided with a heat dissipation fin extending into the receiving gap.

[0020] And / or, a heat conduction coating is arranged between the heat transfer seat and the heat transfer rib.

[0021] By adopting the technical scheme, since one of the heat transfer rib and the heat transfer seat is provided with a receiving gap, and the other is provided with a heat dissipation fin extending into the receiving gap, on the one hand, the contact area between the heat transfer rib and the heat transfer seat is further increased, so as to further improve the heat dissipation effect and the heat dissipation efficiency of the static vortex disc body, on the other hand, the inserted and matched heat dissipation fin and receiving gap also limit the rotation of the heat sink body around the circumferential direction of the exhaust port, so as to further increase the connection stability of the heat sink body and the static vortex disc body.

[0022] Since the heat conduction coating is arranged between the heat transfer seat and the heat transfer rib, the heat at the heat transfer rib can be quickly transferred to the heat transfer seat through the heat conduction coating, so as to improve the heat transfer efficiency between the heat transfer rib and the heat transfer seat, and further improve the heat dissipation effect and the heat dissipation efficiency of the static vortex disc body.

[0023] Optionally, the heat sink body comprises a support plate, and the support plate is provided with heat equalizing fins on one side close to the static scroll body and heat conducting fins on the other side.

[0025] Optionally, the heat equalizing fins and the static scroll body have a heat dissipation gap therebetween.

[0026] By adopting the above technical scheme, since the heat equalizing fins and the static scroll body have a heat dissipation gap therebetween, the contact between the heat sink body and the static scroll body is avoided, so as to further avoid the heat at the exhaust port extending to the bearing seat provided on the static scroll body through the heat sink body, thereby further reducing the temperature at the bearing seat, greatly prolonging the service life of the bearing installed in the bearing seat, and further greatly improving the service life of the scroll air compressor provided with the static scroll.

[0029] By adopting the above technical scheme, since the height H1 of the heat transfer seat is greater than the height H2 of the heat equalizing fins, the heat dissipation gap is formed by the heat transfer seat, so as to avoid the need to provide other structures on the heat sink body or the static scroll body, thereby simplifying the structure of the heat sink body and the static scroll body, and reducing the production cost of the static scroll.

[0030] Since the height H3 of the support column is greater than the height of the heat equalizing fins, the heat dissipation gap is formed by the heat transfer seat, so as to increase the contact points between the heat sink body and the static scroll body, thereby increasing the connection stability of the heat sink body and the static scroll body.

[0031] Optionally, the back surface of the static scroll body comprises a platform area and a heat transfer fin area provided on the periphery of the platform area.

[0032] By adopting the above technical scheme, since the side of the static vortex disc body is provided with the bearing seat, and the static vortex disc body comprises a platform area and a heat transfer fin area arranged on the side of the platform area, heat at the bearing seat can be quickly transferred to the outside of the static vortex disc body through the heat transfer fin area, so as to further reduce the temperature at the bearing seat, thereby further improving the service life of the bearing installed in the bearing seat, and further improving the service life of the scroll air compressor provided with the static vortex disc in the application.

[0033] Optionally, the static vortex disc body and the heat sink body are connected by screws.

[0055] Reference Figures 1 to 5 , discloses a static scroll for a scroll air compressor, which includes a static scroll body 1, a radiator body 2 and a heat transfer structure 3, wherein the static scroll body 1 has a front side on which a vortex tooth is provided and a back side opposite to the front side, and the static scroll body 1 has an exhaust port 11; the radiator body 2 is provided on the back side of the static scroll body 1 and is separately provided from the static scroll body 1; the heat transfer structure 3 is provided at the exhaust port 11 and is located between the exhaust port 11 and the radiator body 2 to transfer the heat at the exhaust port 11 to the radiator body 2.

[0056] Since the radiator body 2 is arranged on the back of the static vortex body 1 and is separated from the static vortex body 1, the structural design of the back of the static vortex body 1 is simplified, so that the back of the static vortex body 1 can be designed as a larger plane, thereby simplifying the structure of the shielding tooling and reducing the production cost of the shielding tooling. At the same time, it is easy to install the shielding tooling on the back of the static vortex body 1, so as to reduce the time cost of installing the shielding tooling, thereby improving the oxidation treatment efficiency of the static vortex body 1, and improving the production efficiency of the static vortex. In addition, this setting can oxidize the static vortex body 1 alone, while the radiator body 2 is not oxidized, thereby ensuring the thermal conductivity of the radiator body 2 and improving the heat dissipation capacity of the static vortex.

[0057] And, since the temperature of the gas discharged through the exhaust port 11 is relatively high when the scroll air compressor is working, the temperature of the static vortex disc body 1 on the side of the exhaust port 11 is relatively high, and the heat transfer structure 3 is arranged between the exhaust port 11 and the radiator body 2, so that the heat at the exhaust port 11 is transferred to the radiator body 2 through the heat transfer structure 3, thereby improving the heat dissipation effect at the exhaust port 11, greatly reducing the temperature at the exhaust port 11, and further greatly improving the heat dissipation effect of the static vortex disc; at the same time, the heat at the exhaust port 11 is reduced. The heat is transferred laterally along the static vortex disc body 1 to the bearing seat 14, avoiding the influence of heat transfer on the service life of the bearing installed in the bearing seat 14, thereby greatly improving the service life of the bearing.

[0058] The present application does not make specific limitations to the heat transfer structure 3, preferably, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the heat transfer structure 3 includes a heat transfer seat 31 arranged on the radiator body 2 and a heat transfer rib 32 arranged on the static vortex disc body 1, the heat transfer rib 32 is in contact with the heat transfer seat 31, and then the heat at the exhaust port 11 is transferred to the heat transfer seat 31 through the heat transfer rib 32, so as to realize the heat at the exhaust port 11 is transferred to the heat transfer seat 31 through the heat transfer structure 3, thereby improving the heat dissipation effect and efficiency of the static vortex disc body 1.

[0059] Further, referring to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the heat transfer rib 32 is arranged along the circumference of the exhaust port 11 and extends into the heat transfer seat 31, and the outer circumferential surface of the heat transfer rib 32 is in contact with the inner circumferential surface of the heat transfer seat 31.

[0060] That is, the heat transfer rib 32 is in plug-in cooperation with the heat transfer seat 31, on the one hand, the plug-in cooperation of the heat transfer rib 32 and the heat transfer seat 31 realizes the positioning of the radiator body 2, thereby reducing the difficulty of fixing the radiator body 2 and improving the fixing effect of the radiator body 2, on the other hand, the contact area of the heat transfer rib 32 and the heat transfer seat 31 is increased, thereby greatly improving the heat transfer efficiency between the heat transfer rib 32 and the heat transfer seat 31, and further greatly improving the heat dissipation effect and efficiency of the static vortex disc body 1. At the same time, compared with the heat transfer rib 32 being arranged on the outside of the heat transfer seat 31, the exhaust area of the exhaust port 11 is ensured to ensure the smoothness of the exhaust.

[0061] Further, referring to Figure 2, the diameter of the heat transfer rib 32 gradually decreases in the direction away from the static vortex disc body 1, the inner circumferential surface of the heat transfer seat 31 is matched with the heat transfer rib 32, on the one hand, the diameter of the heat transfer rib 32 away from the static vortex disc body 1 is smaller than the diameter of the heat transfer rib 32 close to the static vortex disc body 1, so that when the radiator body 2 is assembled, the end of the heat transfer rib 32 away from the static vortex disc body 1 can guide the radiator body 2, so as to facilitate the assembly of the radiator body 2, on the other hand, the contact area between the heat transfer rib 32 and the heat transfer seat 31 is further increased, so as to further improve the heat dissipation effect and efficiency of the static vortex disc body 1.

[0063] Preferably, referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the heat transfer rib 32 is provided with a plurality of receiving gaps 321 along the circumference thereof, and the heat transfer seat 31 is provided with a plurality of heat dissipation tabs 311 corresponding to the plurality of receiving gaps 321, so as to further reduce the production difficulty of the static vortex disc, improve the production efficiency and reduce the production cost.

[0064] Further, a heat-conducting coating is arranged between the heat transfer seat 31 and the heat transfer rib 32, so that the heat at the heat transfer rib 32 can be quickly transmitted to the heat transfer seat 31 through the heat-conducting coating, thereby improving the heat transfer efficiency between the heat transfer seat 31 and the heat transfer rib 32, and further improving the heat dissipation effect and efficiency of the static vortex disc body 1.

[0065] Preferably, the heat-conducting coating is a heat-conducting silicone grease coated on the heat transfer seat 31 and the heat transfer rib 32, so as to improve the heat transfer efficiency between the heat transfer seat 31 and the heat transfer rib 32.

[0066] In other embodiments, the heat transfer structure 3 can also be a mica sheet or a superconducting element arranged between the exhaust port 11 and the radiator body 2, so as to quickly transmit the heat at the exhaust port 11 to the radiator body 2 through the mica sheet or the superconducting element.

[0067] In a preferred embodiment, referring to Figure 2 、 Figure 3 and Figure 4 The radiator body 2 includes a support plate 21, and a heat-equalizing fin 22 is provided on one side of the support plate 21 close to the static scroll body 1, and a heat-conducting fin 23 is provided on the other side, so that the heat transferred to the radiator body 2 through the heat transfer structure 3 can be quickly transferred along the horizontal direction of the support plate 21 through the heat-equalizing fin 22, so as to quickly transfer the heat to the edge of the support plate 21, so as to greatly improve the heat dissipation effect and heat dissipation efficiency of the radiator body 2, thereby further improving the temperature difference between the radiator body 2 and the static scroll body 1, so as to further improve the heat dissipation effect and heat dissipation efficiency of the static scroll body 1.

[0068] Further, refer to Figure 1 There is a heat dissipation gap 12 between the heat-equalizing fins 22 and the static scroll body 1, thereby avoiding the contact between the radiator body 2 and the static scroll body 1, and further avoiding the heat at the exhaust port 11 from extending laterally through the radiator body 2 to the bearing seat 14 provided on the static scroll body 1, thereby further reducing the temperature at the bearing seat 14, and greatly extending the life of the bearing installed in the bearing seat 14, thereby greatly improving the service life of the vortex air compressor equipped with the static scroll in this application.

The height H1 of the heat transfer seat 31 and the height H2 of the heat fin 22 satisfy: H1>H2.

[0071] It can be understood that after the radiator body 2 is assembled on the static scroll body 1, the heat transfer seat 31 contacts the back of the static scroll body 1. Since the height H1 of the heat transfer seat 31 is greater than the height H2 of the heat equalizing fin 22, there is a gap between the heat equalizing fin 22 and the back of the static scroll body 1, so as to avoid the need to set other structures on the radiator body 2 or the static scroll body 1, thereby simplifying the structure of the radiator body 2 and the static scroll body 1, so as to reduce the production cost of the static scroll.
