Description

Technical Field

[0001] This utility model relates to an on-board thermal management system, and more particularly to a drug-side integrated system that integrates gas replenishment and enthalpy enhancement functions. 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] The aforementioned refrigerant replenishment function is mostly achieved by the economizer directly adding refrigerant to the compressor. The economizer itself needs to be connected to the compressor, water cooler, and refrigeration unit via specially designed pipelines. It is worth noting that in existing designs, the economizer is often installed in an unreasonable location, such as on the side wall of the compressor. This results in a bulky overall structure of the refrigerant-side integrated system, making maintenance difficult and occupying a large amount of vehicle interior space, thus reducing its practicality.

[0044] Please see Figure 1 This embodiment describes a drug-side integrated system with integrated gas replenishment and enthalpy enhancement functions, wherein the drug-side integrated system with integrated gas replenishment and enthalpy enhancement functions includes:

[0045] The compressor 1 has a first end and a second end that are disposed opposite to each other. The first end of the compressor 1 is equipped with an outer cover 18, and the second end of the compressor 1 is equipped with a controller 9.

[0046] Valve island 2 is installed on the top surface of compressor 1; water cooler 2, refrigerator 3, liquid storage tank 4, economizer 5, first expansion valve 6, and second expansion valve 7 are fixedly connected to valve island 8 and installed on the top surface of compressor 1; wherein, economizer 5 is installed on one side of the first end of valve island 8, and economizer 5 is connected to the outer cover 18 of compressor 1 through guide pipe 55 and supplies gas to compressor 1.

[0047] Based on the above-described structure of this utility model, the various components can be integrated through the valve island 8, and gas replenishment can be achieved through the end intake of the compressor 1. Its structure is small in size and has a short gas replenishment channel 181. Specifically, in the structure of this utility model, by fixing the valve island 8 to the top of the compressor 1, the valve island 8 connects the corresponding water cooler 2, refrigerant 3, liquid receiver 4, economizer 5, first expansion valve 6, and second expansion valve 7, forming a highly integrated refrigerant-side integrated system that is small in size and easy to maintain. Meanwhile, the economizer 5 in this utility model is located near the end of the compressor 1 and directly replenishes the gas inside the compressor 1 through the end cover 18 of the compressor 1. Its gas replenishment channel is shorter than that of the economizer 5 installed on the opposite side. The valve island 8 not only serves to fix the aforementioned components such as the water cooler 2, refrigerant 3, liquid receiver 4, economizer 5, first expansion valve 6, and second expansion valve 7, but can also connect with any of the aforementioned components, allowing the refrigerant to flow through according to the corresponding flow lines.

[0048] For details regarding the gas replenishment and enthalpy increase section in this application, please refer to [link to relevant documentation]. Figure 1-3 The compressor 1 has a stationary plate 14 at one end, a groove 141 on the first end face of the stationary plate 14, a raised support portion 142 on the first end face of the groove 141, and an air inlet 143 communicating with the groove 141 on the second end face of the stationary plate 14. A gas replenishment and enthalpy enhancement device is also installed between the stationary plate 14 and the outer cover 18. The gas replenishment and enthalpy enhancement device includes a gas replenishment pipe 15, a connecting plate 151 at the second end of the gas replenishment pipe 15, and the connecting plate... 151 is installed in the groove 141; cover plate 16, the cover plate 16 is disposed between the second end face of the connecting plate 151 and the support portion 142 of the groove 141, the cover plate 16 is provided with a through hole 161, the through hole 161 and the first end face of the groove 141 form a gap; valve plate 17, the fixed end 171 of the valve plate 17 is fixedly connected to the second end face of the cover plate 16, and the movable end 172 of the valve plate 17 is disposed at the through hole 161 of the cover plate 16. Specifically, during installation, the stationary plate 14 can be fixed to one side of the first end of the compressor cylinder 1. Based on the position of the groove 141 on the stationary plate 14, the fixed end 171 of the valve plate 17 can be fixed to one side of the second end face of the cover plate 16. Then, the cover plate 16 with the valve plate 17 connected to it can be aligned with the position of the groove 141 and installed in the groove 141, so that the position of the movable end 172 of the valve plate 17 is aligned with the position of the groove 141 and the air inlet 143. Then, the connecting plate 151 is installed on the outside of the cover plate 16, and the connecting plate 151 is fixed in the groove 141 by bolts 152, so that the cover plate 16 is also clamped in the groove 141.

[0049] When there is no air intake in the closed state, the movable end 172 of the valve plate 17 is close to and covers the entire through hole 161 of the cover plate 16, so that the through hole 161 is isolated from the air intake hole 143. At this time, the valve plate 17 blocks the through hole 161. Considering that the valve plate 17 can only bend and deform to the side away from the cover plate 16, the refrigerant in the compressor cylinder 1 cannot enter the air supply pipe 15 in reverse.

[0050] During the gas replenishment process, the gas replenishment pipe 15 is in a ventilated state. The valve plate 17 deforms under the action of gas pressure, and the movable end 172 of the valve plate 17 separates from the cover plate 16, so that the air inlet 143 and the through hole 161 are connected. Specifically, the gas replenishment pipe 15 injects refrigerant gas from the first end to the second end. The valve plate 17 can bend and deform to the side away from the cover plate 16, so that a space for gas to pass through is created between the valve plate 17 and the through hole 161 of the cover plate 16. Therefore, the refrigerant gas can pass through the through hole 161 of the cover plate 16 and pass through the groove 141 and the air inlet 143 in sequence through the stationary plate 14 and enter the side of the compressor 1, thus realizing gas replenishment.

[0051] In the above structure, the overall volume can be significantly reduced and installation is easier by placing the gas replenishment and enthalpy enhancement device at the end of the compressor 1, that is, on one side of the stationary plate 14. In use, gas is directly introduced through the stationary plate 14 at the end of the compressor 1 for replenishment. Compared with installing gas replenishment, enthalpy enhancement, and other components on the side wall of the compressor 1, the overall volume of the compressor 1 is significantly reduced, the integration is higher, and with the cooperation of the cover plate 16 and the valve plate 17, unidirectional control of the gas is achieved with a small axial thickness, resulting in a simple and efficient structure.

[0052] In another embodiment, an outer cover 18 is installed on the first end of the compressor 1, covering at least the entire stationary plate 14. The main function of the outer cover 18 is to serve as a primary protective cover on one side of the first end of the compressor 1, supporting and protecting the internal structure. The outer cover 18 can be directly locked to the cylinder of the compressor 1 body via external bolts. In this embodiment, an air supply channel 181 is provided on the outer cover 18, and the second end of the air supply channel 181 is connected to the first end of the air supply pipe 15. The air supply channel 181 serves as an external interface for air supply to the first end of the compressor 1, directly connected in the direction of the end. Similarly, the outer cover 18 can also be configured to directly communicate with a water cooler for exchanging refrigerant with the water cooler, passing through the stationary plate 14 and entering the interior of the compressor 1.

[0053] In other words, the aforementioned air replenishment and the refrigerant intake on the main refrigeration unit side are both located on the outer cover 18 side, which has a high degree of integration.

[0054] In this embodiment, the stationary plate 14 is provided with a plurality of air inlets 143, each air inlet 143 corresponding to a valve plate 17. The plurality of valve plates 17 share the same connecting plate 151. The first end face of the cover plate 16 is provided with a protruding isolation portion 162, and the second end face of the cover plate 16 abuts against the isolation portion 162, so that a gap is formed between the second end face of the cover plate 16 and the through hole 161. Specifically, the above-mentioned combination of air inlets 143 and valve plates 17 can be set as two. In this embodiment, one of the air inlets 143 is directly opposite to the air supply pipe 15. The refrigerant injected into the second end of the air supply pipe 15 can directly push open the adjacent valve plate 17 and directly enter the air inlet 143 in the groove 141. The other part of the refrigerant injected into the second end of the air supply pipe 15 can flow through the gap between the isolation portion 162 and the connecting plate 151 to the position of another spaced air inlet 143, and replenish air from the corresponding air inlet 143 of the other spaced groove 141.

[0055] The aforementioned air supply pipe 15 can supply air to multiple air inlets 143 at different positions, making the air supply effect more uniform.

[0056] Furthermore, in the above embodiments, when there is only one combination of an air inlet 143 and a corresponding valve plate 17, the positions of the air inlet 143 and the through hole 161 are matched, and the air intake path of this air inlet 143 is the shortest and most unobstructed. When there are multiple sets of air inlets 143 and valve plates 17, at least one set is where the positions of the air inlet 143 and the through hole 161 are matched.

[0057] In this embodiment, the valve plate 17 has a preset stiffness so that, in the air supply state, the movable end 172 of the valve plate 17 can never cover the air inlet 143. That is, based on the air intake at the second end of the air supply pipe 15 and the push on the valve plate 17, the bending deformation of the valve plate 17 is always controlled by the above-mentioned stiffness setting, so as to avoid the valve plate 17 blocking the air inlet 143 in the corresponding groove 141, which would prevent the compressor 1 from being supplied with air.

[0058] In fact, in the above-described embodiment with multiple air inlets 143, the groove 141 where the multiple air inlets 143 are located can connect the air inlets 143 in series to form a complete multi-segment or arc-shaped groove 141. The connecting plate 151 and the cover plate 16 are set to be equally matched and embedded in the groove 141 in an arc or multi-segment shape.

[0059] For details regarding the design and structural installation components of valve island 8 in this application, please refer to [link / reference]. Figure 4-10The 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 storage tank 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 storage tank 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.

[0060] 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.

[0061] 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...

[0062] Please refer to the perspective view of the economizer from the fifth side of this application. Figure 4 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.

[0063] 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. 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.

[0064] 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 first expansion valve 6 through the second channel 82;

[0065] The valve island's channel cross-section is shown in the attached figure of this application. Figure 8 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;

[0066] The valve island's channel cross-section is shown in the attached figure of this application. Figure 9 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;

[0067] The valve island's channel cross-section is shown in the attached figure of this application. Figure 10 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;

[0068] The valve island's channel cross-section is shown in the attached figure of this application. Figure 9 As 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.

[0069] Please refer to the perspective view of the economizer from the fifth side of this application. Figure 4 The second outlet 54 is connected to the air supply port 13 through the guide pipe 55.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] In this application, when installing the agent-side integrated system, the water cooler 2, the liquid storage tank 4, and the economizer 5 can be installed horizontally on the side of the valve island 8; the first expansion valve 6 and the second expansion valve 7 can be installed vertically on the top of the valve island 8; the valve island 8 can be installed vertically on the top surface of the compressor 1, and the exhaust port 11 of the compressor 1 can be vertically connected to the water cooling inlet 21 of the water cooler 2; the first end of the compressor 1 can be connected to the first end of the economizer 5 through the guide pipe 55; and the cooler 3 can be installed horizontally on one side of the valve island 8. Specifically, the cooler 3 is installed on the side of the valve island 8 away from the water cooler 2, and the liquid storage tank 4 is installed on the side of the valve island 8 away from the economizer 5. The above installation method is mainly from top to bottom, with the compressor 1 as the center, and all the main components are located at the top of the compressor 1, which has better stability and is easy to maintain.
