Description

Technical Field

[0001] This utility model relates to an on-board thermal management system, and more particularly to a valve island for a compressor. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] In thermal management systems, heat exchange is typically achieved by compressing the refrigerant with a compressor and then utilizing the refrigerant's temperature changes. However, in certain scenarios, especially in low-temperature environments, the low evaporation pressure of the heat pump can lead to a low intake density in the compressor, resulting in a reduced refrigerant mass flow rate and a high exhaust temperature. This forces the compressor to operate under high load, affecting its temperature regulation capabilities and even its lifespan. Therefore, methods for adding refrigerant to the compressor exist to alleviate these problems.

[0004] In the existing design, the integration layout on the compressor side is affected by the intervention of components and pipelines such as gas injection and enthalpy enhancement. In the existing pipeline design, the external economizer is generally suspended on the side of the compressor and connected to the original system through an independent pipeline, resulting in a large size and inconvenience for installation and maintenance.

[0024] Please see Figure 1-2 This is a valve island for a compressor in this embodiment, which is also provided with a water cooler 2, a refrigeration unit 3, a liquid storage tank 4, an economizer 5, a first expansion valve 6, and a second expansion valve 7. The valve island 8 is installed on the top surface of the compressor 1. The water cooler 2, the refrigeration unit 3, the liquid storage tank 4, the economizer 5, the first expansion valve 6, and the second expansion valve 7 are fixedly connected to the valve island 8 and communicate with it respectively, and are finally installed on the top surface of the compressor 1.

[0025] Based on the above structure, the valve island 8 itself can be set as a separate box-shaped block. During installation, the components of the water cooler 2, the refrigeration unit 3, the liquid receiver 4, the economizer 5, the first expansion valve 6, and the second expansion valve 7 can be pre-connected to the valve island 8, and the valve island 8 can be installed on the top surface of the compressor 1 and fixed with bolts, so that the above-mentioned components and the valve island 8 are fixed on the compressor 1. Then, all the remaining components of the water cooler 2, the refrigeration unit 3, the liquid receiver 4, the economizer 5, the first expansion valve 6, and the second expansion valve 7 are fixed on the installed valve island 8, so that all the components are fixed on the compressor 1 with the support of the valve island 8.

[0026] Based on the structure described above in this application, the corresponding components, including the economizer 5, can be integrated into the compressor 1 through the intervention of the valve island 8, resulting in high integration and ease of installation. Specifically, the valve island 8 itself can not only serve as a flow channel bridge connecting the compressor 1, water cooler 2, refrigerator 3, liquid receiver 4, economizer 5, first expansion valve 6, and second expansion valve 7, but also, by being fixed above the compressor 1 body, act as a stable support, thereby fixing the water cooler 2, refrigerator 3, liquid receiver 4, economizer 5, first expansion valve 6, and second expansion valve 7 onto the compressor 1 using the valve island 8 itself. This results in high structural stability and a higher degree of integration.

[0027] Specifically, in this application, the compressor 1 has an exhaust port 11, an intake port 12, and a make-up port 13; the water cooler 2 includes a water-cooled inlet 21 and a water-cooled outlet 22; the refrigerator 3 includes a refrigeration inlet 31 and a refrigeration outlet 32; the liquid storage tank 4 includes a liquid storage inlet 41 and a liquid storage outlet 42; the economizer 5 includes a first inlet 51, a first outlet 52, a second inlet 53, and a second outlet 54; and the valve island 8 forms independent first channels 81, second channels 82, third channels 83, fourth channels 84, fifth channels 85, and sixth channels 86, wherein... Please refer to the perspective view of the economizer from the fifth side of this application. Figure 1 The exhaust port 11 is directly connected to the water cooling inlet 21; the water cooling outlet 22 is directly connected to the liquid storage inlet 41. The schematic diagram of the channel cross-section of the valve island is shown in the attached figure of this application. Figure 3 As shown, it is a cross-sectional view of a horizontal section. The liquid storage outlet 42 is connected to the first inlet 51 through the first channel 81, and is connected to the first outlet 52 through the economizer 5. The schematic diagram of the channel cross-section of the valve island is shown in the attached figure of this application. Figure 4 As shown, it is a cross-sectional view of a horizontal section, with the first outlet 52 connected to the first expansion valve 6 through the second channel 82; The schematic diagram of the channel cross-section of the valve island is shown in the attached figure of this application. Figure 5 As shown, it is a cross-sectional view of a horizontal section, in which the first expansion valve 6 is connected to the refrigeration inlet 31 through the third channel 83; The valve island's channel cross-section is shown in the attached figure of this application. Figure 6 As shown, it is a cross-sectional view of a horizontal section, with the refrigeration outlet 32 ​​connected to the suction port 12 through the fourth channel 84; The valve island's channel cross-section is shown in the attached figure of this application. Figure 7 As shown, it is a cross-sectional view of a horizontal section, with the first outlet 52 connected to the second expansion valve 7 through the fifth channel 85; The valve island's channel cross-section is shown in the attached figure of this application. Figure 6As shown, it is a cross-sectional view of a horizontal section. The second expansion valve 7 is connected to the second inlet 53 through the sixth channel 86, and is connected to the second outlet 54 through the economizer 5. Please refer to the perspective view of the economizer from the fifth side of this application. Figure 1 The second outlet 54 is connected to the air supply port 13 via a guide pipe 55. Specifically, the routing of the above channels can be found in [reference needed]. Figure 3-9 The valve island 81 has the following channels: First channel 81 extends from its first end along the X-axis to its second end along the Y-axis; Second channel 82 extends from its first end along the Y-axis to its second end, and is positioned at the top of first channel 81 along the Z-axis; Third channel 83 extends from its first end along the Z-axis to its bottom, and then to its second end along the X-axis; Fourth channel 84 extends from its first end along the X-axis to its second end, and is positioned at the bottom of third channel 83 along the Z-axis; Fifth channel 85 extends from its first end along the Y-axis to its second end, and shares the same Y-axis direction as second channel 82; Sixth channel 86 extends from its first end along the Y-axis to its second end, and is at the same height as second channel 82 along the Z-axis. These channels are staggered to fully utilize the internal space of the valve island 8.

[0028] Based on the above structural scheme, in the specific operation of this application, after the compressor 1 pressurizes the refrigerant, it discharges the refrigerant directly from the exhaust port 11 into the water-cooled inlet 21. After entering the water-cooled inlet 21, the refrigerant and the coolant in the water cooler 2 are thermally coupled and then flow out from the water-cooled outlet 22. The refrigerant flows to the liquid storage inlet 41 and flows from top to bottom from the liquid storage outlet 42 into the first channel 81. Then it is guided to the first inlet 51 of the economizer 5. After passing through the economizer 5, it flows out from the first outlet 52. Then, one stream of refrigerant is guided by the second channel 82 to the first expansion valve 6. After depressurization and expansion, it enters the refrigeration inlet 31 from the third channel 83 and is thermally coupled with the coolant in the refrigerator 3. Then it flows out from the refrigeration outlet 32. The refrigerant returns to the compressor from the suction port 12 under the guidance of the fourth channel 84.

[0029] After passing through the economizer 5, another stream of refrigerant flows out from the first outlet 52 to the fifth channel 85, and is guided into the second expansion valve 7. After being throttled by the second expansion valve 7, it returns to the economizer 5 through the sixth channel 86 from the second inlet 53, where it exchanges heat with the refrigerant that first entered the economizer 5. Then it flows out from the second outlet 54 and enters the compressor 1 through the gas supply port 13 via the guide pipe 55, thus replenishing the compressor 1 with gas.

[0030] In another embodiment, the first inlet 51, the first outlet 52, and the second inlet 53 of the economizer 5 are located on the same side facing the valve island 8 and are respectively connected to the valve island 8. The second outlet 54 of the economizer 5 is located on the side facing away from the valve island 8 and is connected to the air supply port 13 of the compressor 1 through a guide pipe 55. That is to say, the same side of the valve island 8 in this application simultaneously connects to three channels, and as... Figure 1 The economizer 5 shown faces outwards and is replenished with gas through a single guide pipe 55. Its external pipeline is only the guide pipe 55 itself, while the main pipeline channels are all located on the internal side, resulting in a high degree of integration.

[0031] In this application, compressor 1 has a first end and a second end arranged opposite to each other. Economizer 5 is located on the side adjacent to the first end of compressor 1, liquid storage tank 4 is located on the side adjacent to the second end of compressor 1, and valve island 8 is located between the first end and the second end of compressor 1. Further, water cooler 2 and refrigeration unit 3 are respectively located between the first end and the second end of compressor 1 and are respectively suspended and fixed on opposite sides of valve island 8. Further, first expansion valve 6 and second expansion valve 7 are installed at the top of valve island 8. Therefore, based on valve island 8, a balanced "airplane-shaped" layout is actually formed, with valve island 8 and compressor 1 as the main cabin, water cooler 2 and refrigeration unit 3 with larger volume and weight as wings on both sides, and liquid storage tank 4 and economizer 5 with smaller volume and comparable weight as the nose and tail respectively. The weight is relatively balanced. Specifically, compressor 1 has a preset center of mass, and the center of mass formed by water cooler 2, refrigeration unit 3, liquid storage tank 4, economizer 5, first expansion valve 6, second expansion valve 7 and valve island 8 is close to or located on the vertical plane of the preset center of mass. By balancing the center of gravity as described above, not only can the integration be improved, but the overall structure can also have stronger stability during vehicle operation, avoiding the situation where some connection points are subjected to excessive stress and the structure becomes loose due to long-term displacement caused by an unbalanced center of gravity.

[0032] In this application, a controller 9 is also installed on one side of the second end of the compressor 1, with its end slightly protruding to the top surface of the compressor 1, forming a better balance with the first end.

[0033] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0034] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0035] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
