Description

Technical Field

[0001] This utility model relates to an on-board thermal management system, and more particularly to an integrated gas injection and enthalpy enhancement device for an on-board 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] However, in vehicle scenarios, especially electric and hybrid vehicles, there are high requirements for the size of the internal components. Existing gas injection and enthalpy enhancement systems for compressors are generally located on one side of the compressor, which is large and difficult to meet the installation requirements.

[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.

[0012] In the closed state, the movable end of the valve plate is pressed against and covers all the through holes of the cover plate, so that the through holes are isolated from the air inlet.

[0013] When the air is ventilated, the valve plate deforms under air pressure, and the movable end of the valve plate separates from the cover plate, so that the air inlet and the through hole are connected.

[0014] As a further description of the above technical solution, the integrated gas replenishment and enthalpy enhancement device for the vehicle compressor also includes an outer cover, which is disposed on the first end of the compressor and covers at least the entire static plate.

[0019] As a further description of the above technical solution, the positions of the air inlet and the through hole are matched.

[0020] As a further description of the above technical solution, the valve plate has a preset stiffness so that the movable end of the valve plate can never cover the air inlet when the air is ventilated.

[0021] As a further description of the above technical solution, the connecting plate is fixed to the first end face of the stationary plate by a plurality of bolts that avoid the groove.

These terms are primarily used to distinguish one component from another, or one signal from another.

[0037] Please see Figure 1-4 This embodiment describes an integrated gas-injection and enthalpy-boosting device for an on-board compressor. The compressor 1 has a first end and a second end disposed opposite to each other. The first end of the compressor 1 is covered with a stationary plate 14. A groove 141 is formed on the first end face of the stationary plate 14, and a protruding support portion 142 is formed on the first end face of the groove 141. An air inlet 143 communicating with the groove 141 is formed on the second end face of the stationary plate 14. The integrated gas-injection and enthalpy-boosting device for an on-board compressor includes:

[0038] The air supply pipe 15 has a connecting plate 151 at its second end, and the connecting plate 151 is installed in the groove 141.

[0039] Cover plate 16 is disposed between the second end face of connecting plate 151 and the support portion 142 of groove 141. Cover plate 16 is provided with through hole 161, and a gap is formed between through hole 161 and the first end face of groove 141.

[0040] Valve plate 17, the fixed end 171 of valve plate 17 is fixedly connected to the second end face of cover plate 16, and the movable end 172 of valve plate 17 is set at the through hole 161 of cover plate 16.

[0041] Based on the above structure, during installation, the stationary plate 14 can be fixed to one side of the first end of the compressor 1 cylinder. 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 installed in the groove 141, with the movable end 172 of the valve plate 17 aligned with 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] In another embodiment, the integrated gas injection and enthalpy enhancement device for the vehicle-mounted compressor also includes an outer cover 18, which is installed on the first end of the compressor 1 and covers 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 by external bolts. In this embodiment, the outer cover 18 is provided with a gas injection channel 181, the second end of which is connected to the first end of the gas injection pipe 15. The gas injection channel 181 serves as an external interface for gas injection at 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.

[0046] 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.

[0047] 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.

[0048] The aforementioned air supply pipe 15 can supply air to multiple air inlets 143 at different positions, making the air supply effect more uniform.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.
