Description

Technical Field

[0001] This application relates to the field of scroll compressor technology, and in particular to a scroll plate temperature regulation structure and a scroll compressor. Background Technology

[0002] The compressor is a crucial component of a refrigeration system. It compresses low-temperature, low-pressure gaseous refrigerant into high-temperature, high-pressure gas, thereby driving the refrigerant circulation and continuously providing power for the refrigeration system. The refrigerant enters through the suction pipe, is compressed by the scroll assembly, transforming from a low-temperature, low-pressure gas into a high-temperature, high-pressure gas. It then flows downwards through the gas passage and finally exits through the discharge pipe. During operation, the scroll assembly heats up due to the temperature of the refrigerant and friction, causing a rapid temperature increase. As the temperature of the scroll assembly rises, its material deforms due to thermal expansion, reducing the gap between the stationary and moving scrolls or even causing them to come into contact. This severely impacts the energy efficiency and reliability of the scroll compressor.

[0003] Currently, scroll compressors typically prevent interference from thermal expansion of the scroll assembly by incorporating pre-existing clearances in the design. However, due to varying temperature rises in different parts of the scroll assembly during operation and differences in temperature under different operating modes, the pre-existing clearances may be too large, impacting energy efficiency. Furthermore, designing pre-existing clearances in the scroll assembly increases the difficulty of machining, leading to higher manufacturing costs. Utility Model Content

[0030] like Figure 1 and Figure 2 As shown, according to a first aspect of the present invention, a vortex disk temperature regulating structure is provided, which includes a fluid tube assembly, a stationary vortex disk 2, and a heat exchange channel 3.

[0031] In the following description, reference will be made to Figures 1 to 2 The specific structure of the components of the scroll plate temperature regulation structure and the connection relationship of the components are described in detail.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the fluid pipe assembly can be installed through the casing 4 of the scroll compressor, allowing cooling fluid to flow in or out through the fluid pipe assembly. The fluid pipe assembly can be inserted into the stationary scroll plate 2. A heat exchange channel 3 can be disposed within the stationary scroll plate 2, and the fluid pipe assembly can be connected to the heat exchange channel 3. This arrangement allows the cooling fluid (e.g., coolant or gaseous refrigerant) to flow into the heat exchange channel 3 through the fluid pipe assembly and exchange heat with the stationary scroll plate 2, thereby cooling the scroll plate assembly (i.e., the stationary scroll plate 2 and the moving scroll plate) to prevent the scroll plate assembly from expanding after heating, which could affect the energy efficiency and reliability of the scroll compressor.

[0033] Preferred, such as Figure 1 and Figure 2 As shown in the embodiment, the stationary scroll plate 2 includes a scroll plate body 21 and a cover plate 22. Stationary scroll teeth 20 are provided at the bottom of the scroll plate body 21. A moving scroll plate can be disposed below the stationary scroll plate 2. The moving scroll teeth of the moving scroll plate mesh with the stationary scroll teeth 20 of the scroll plate body 21. The cover plate 22 can cover the top of the scroll plate body 21, that is, the cover plate 22 and the stationary scroll teeth 20 are respectively disposed on both sides of the stationary scroll plate 2. The heat exchange channel 3 is disposed between the scroll plate body 21 and the cover plate 22.

[0034] However, this is not the only option. The arrangement of the heat exchange channel 3 between the vortex disk body 21 and the cover plate 22 is only a preferred embodiment. As long as the static vortex disk 2 can be cooled, the heat exchange channel 3 can also be arranged in other locations. For example, the heat exchange channel can be formed inside the cover plate, and the cooling fluid can first exchange heat with the cover plate, and then the cover plate can exchange heat with the vortex disk body.

[0035] Preferred, such as Figure 1 and Figure 2As shown, in this embodiment, the top of the scroll plate body 21 may be provided with a groove, which can be sandwiched with the cover plate 22 to form a heat exchange channel 3. Specifically, the top surface of the scroll plate body 21 and the bottom surface of the cover plate 22 may be formed as horizontal surfaces, so that the cover plate 22 can tightly cover the top of the scroll plate body 21 to prevent the cooling fluid from leaking from the stationary scroll plate 2. The groove may be recessed from the top surface of the scroll plate body 21 into the interior of the scroll plate body 21, so that when the cover plate 22 covers the top surface of the scroll plate body 21, the opening of the groove can be completely closed, thereby forming the heat exchange channel 3. The cross-section of the groove may be circular to facilitate its fit with the fluid pipe assembly.

[0036] Preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, the groove can be an annular groove. Specifically, the groove can extend circumferentially along the main body 21 of the vortex disk. The groove can be formed as an incomplete ring (i.e., the beginning and end of the ring are not connected) to prevent fluid from flowing directly from one end of the groove to the other. However, this is not a limitation; setting the groove as an annular shape is only a preferred embodiment. The groove can also be formed in other ways, for example, a vortex-shaped groove can be provided on the top surface of the vortex disk body.

[0037] In addition, preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, an axially extending intake port 50 and a refrigerant outlet 6 may also be provided on the stationary vortex disk 2. The intake port 50 can be connected to the bottom end of the intake pipe 5, and the refrigerant outlet 6 communicates with the compression chamber. The groove is designed to avoid the intake port 50 and the refrigerant outlet 6, thereby preventing fluid leakage from the heat exchange channel 3 into the intake port 50 or the refrigerant outlet 6.

[0038] Preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, the outer periphery of the cover plate 22 may be provided with a plurality of first threaded holes 220, which are spaced apart from each other. Correspondingly, the outer periphery of the top of the scroll plate body 21 is provided with a plurality of second threaded holes, and the plurality of first threaded holes 220 may be aligned with the plurality of second threaded holes, so that the cover plate 22 and the scroll plate body 21 can be connected by screws 23.

[0039] Preferred, such as Figure 1 and Figure 2As shown, in this embodiment, the fluid piping assembly may include an inlet pipe 11 and an outlet pipe 12, wherein the inlet pipe 11 is used for fluid inflow and the outlet pipe 12 is used for fluid outflow. The ends of the inlet pipe 11 and the outlet pipe 12 located outside the pipe shell 4 may be fitted with threaded pipe fittings to facilitate connection of the fluid piping assembly to the water circulation system of a chiller or heat pump system, or to the evaporator and condenser of an air conditioning system via piping. The cover plate 22 has a first port 221 and a second port 222. The first port 221 and the second port 222 may be connected to the two ends of the heat exchange channel 3, respectively. The inlet pipe 11 is inserted into the first port 221, and the outlet pipe 12 is inserted into the second port 222. Preferably, the inlet pipe 11 and the first port 221 may have a clearance fit, and the outlet pipe 12 and the second port 222 may have a clearance fit. This configuration allows the fluid to flow into the heat exchange channel 3 through the inlet pipe 11 for heat exchange, and then flow out through the outlet pipe 12 after heat exchange is completed, thus achieving circulation.

[0040] More preferably, in this embodiment, the number of inlet pipes 11 and outlet pipes 12 can be equal to the number of heat exchange channels 3. Preferably, when there are multiple heat exchange channels 3, for example, multiple non-interconnected heat exchange channels 3 are provided within the static vortex disk 2. In this case, each heat exchange channel 3 can have an inlet pipe 11 and an outlet pipe 12 at both ends, respectively, to individually control the flow of fluid in each heat exchange channel 3.

[0041] Preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, the fluid tubing can be arranged vertically, meaning the inlet pipe 11 and outlet pipe 12 can be vertically inserted into the top cover 40 of the tubing shell 4. The inlet pipe 11 and outlet pipe 12 can be welded to the top cover 40 or threaded to ensure the airtightness of the tubing shell 4. The positions of the inlet pipe 11 and outlet pipe 12 can correspond to the positions of the first port 221 and the second port 222.

[0042] In addition, such as Figures 1 to 2 As shown, according to a second aspect of the present invention, a scroll compressor is provided, the scroll compressor including the scroll plate temperature regulating structure as described above.

[0043] During operation, the inlet pipe 11 and outlet pipe 12 pass through the top cover 40 of the casing 4 and are connected to the pipe assembly within the stationary scroll plate 2. Cooling fluid flows through the inlet pipe 11 into the heat exchange channel 3 for heat exchange, and then flows out through the outlet pipe 12 after heat exchange is complete. This allows for cooling of the scroll plate assembly, preventing it from expanding when heated, which could negatively impact the energy efficiency and reliability of the scroll compressor.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The scope of protection of this application is not limited thereto.
