Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor; at the same time, the utility model also relates to a thermal management system provided with the compressor. Background Art

[0002] A typical scroll compressor consists of a moving scroll and a stationary scroll. The involute lines on the moving scroll and the stationary scroll mesh with each other, forming a crescent-shaped closed cavity with a gradually decreasing volume from the outside to the inside, namely the suction cavity, the intermediate cavity, and the exhaust cavity. The three cavities continuously inhale, compress and exhaust air from the outside to the inside.

[0003] During winter heating, low intake temperatures result in relatively low compressor exhaust temperatures, resulting in poor heating performance. To increase exhaust temperatures, existing heat pump air conditioning systems incorporate a bypass circuit between the exhaust and intake air streams. A bypass valve in this circuit diverts a certain percentage of high-temperature, high-pressure gas to a gas-liquid separator vessel at the compressor's intake end.

[0004] Although the bypass circuit solution can make the exhaust temperature higher, the heat loss is also greater. In addition, the refrigerant diverted back to the compressor at the suction end will inevitably occupy the compressor's suction volume, causing the system's circulating air volume to decrease. To compensate for the heat loss caused by the diversion, the system has to increase the compressor speed to increase the air volume. As a result, when the system enters the bypass heating mode, the compressor noise increases significantly, affecting the comfort of the thermal management system. In addition, the compressor air inlet is usually equipped with sensors for detecting pressure and / or temperature, but the sensors are relatively scattered, which is not conducive to the integrated design of the compressor.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0034] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," and "back" appear to indicate orientation or positional relationships, these are based on the orientation or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

Therefore, they should not be construed as limitations on this utility model. Furthermore, if terms such as "first" and "second" appear, they are used solely for descriptive purposes and should not be construed as indicating or implying relative importance.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] This embodiment relates to a compressor to solve the problems in the prior art of setting a bypass circuit between the exhaust chamber 300 and the gas-liquid separator in the scroll compressor, which results in large pressure and temperature losses, large compressor heat loss and low integration.

[0037] Overall, the compressor in this embodiment comprises a housing 1 with an accommodating chamber, a scroll assembly 2 disposed within the accommodating chamber, and a control valve 3. The scroll assembly 2 comprises an exhaust chamber 300, an intermediate chamber 200, and an intake chamber 100, arranged radially from the inside out. The control valve 3 is disposed between the exhaust chamber 300 and the intermediate chamber 200 and is used to regulate the flow of gas returning to the intermediate chamber 200. The control valve 3 is provided with a first detection chamber 301 in communication with the intake chamber 100. Within this first detection chamber 301 lies a first detection portion capable of detecting at least the pressure in the intake chamber 100.

[0038] The compressor described in this embodiment sets a control valve 3 between the exhaust chamber 300 and the intermediate chamber 200, so that part of the gas in the exhaust chamber 300 can flow back to the intermediate chamber 200, thereby helping to increase the exhaust temperature of the compressor without affecting the suction volume of the compressor. Compared with the solution of setting a bypass loop between the exhaust chamber 300 and the gas-liquid separator, it helps to reduce heat loss and compressor speed, and can also improve the heating energy efficiency of the whole vehicle, thereby improving the noise comfort and operation reliability of the whole vehicle. By setting the first detection chamber 301 and the first detection part on the control valve 3, a basis is provided for the first detection part and the control valve 3 to share the connector 303, which is beneficial to the integrated design of the compressor.

[0039] Based on the above overall introduction, an exemplary structure of the compressor described in this embodiment is as follows Figure 1 As shown in FIG, the scroll assembly 2 is disposed at one end of the housing 1, with the fixed scroll 201 disposed toward the outside of the housing 1. A control box 104 is provided at the other end of the housing 1, within which the compressor controller is located. A rotating shaft 4 and a motor assembly 5 for driving the rotating shaft 4 are rotatably disposed within the housing 1. A connecting portion 401 eccentrically disposed with respect to the rotating shaft 4 is provided at the free end of the rotating shaft 4. The orbiting scroll 202 is disposed on the connecting portion 401 and moves translationally relative to the fixed scroll 201 as the rotating shaft 4 moves. A support body 402 is provided on the rotating shaft 4 on the other side of the orbiting scroll 202 relative to the fixed scroll 201 to ensure the planar motion of the orbiting scroll 202.

[0040] As a preferred embodiment, the housing 1 in this embodiment includes a housing body 101 with two ends open. Figure 1Based on the perspective in FIG, an end cover 102 is provided at the right end of the shell body 101, and the control box 104 is provided at the left end of the shell body 101. The shell body 101, the end cover 102 and the control box 104 together define the above-mentioned accommodating cavity.

[0041] The structure of the scroll assembly 2 in this embodiment is as follows Figure 3 As shown in FIG, the compressor inlet is provided on the housing 1, and the compressor outlet is provided at the right end of the housing 1. Similar to the molding and arrangement of the cavities in the scroll assembly 2 in the prior art, the discharge cavity 300 is located in the middle of the scroll assembly 2, the intermediate cavities 200 are provided on either side of the discharge cavity 300, and the suction cavities 100 are also provided on the outside of the scroll assembly 2.

[0042] Gas flowing into the casing 1 flows into the scroll assembly 2 through the intake port. As the orbiting scroll 202 translates relative to the stationary scroll 201, the gas flows into the intake chamber 100. From there, it flows into the intermediate chamber 200, where it is compressed. The compressed gas then flows into the exhaust chamber 300, resulting in high-temperature, high-pressure gas within the exhaust chamber 300. Some of the gas within the exhaust chamber 300 is discharged through the exhaust port and flows into the evaporator. Another portion of the gas within the exhaust chamber 300 flows back into the intermediate chamber 200 through the control valve 3, thereby raising the temperature of the gas within the exhaust chamber 300 and enabling the compressor to enhance the heating effect of the thermal management system during winter.

[0043] As a preferred embodiment, Figure 1 and Figure 2 As shown in FIG, the housing 1 is provided with a mounting cavity 103, and the control valve 3 is disposed in the mounting cavity 103. The housing 1 is provided with a first air duct 1021 communicating between the inlet of the control valve 3 and the exhaust cavity 300, and a second air duct 1022 communicating between the outlet of the control valve 3 and the intermediate cavity 200. Moreover, the housing 1 is provided with a third air duct 1023 communicating between the first detection cavity 301 and the suction cavity 100.

[0044] Here, the first air duct 1021 facilitates the flow of gas from the exhaust chamber 300 into the control valve 3, the second air duct 1022 facilitates the flow of gas into the intermediate chamber 200, and the third air duct 1023 facilitates the communication between the inhalation chamber 100 and the first detection chamber 301. The arrangement of the first cavity 1031 and the second cavity 1032 facilitates the flow of gas through the control valve 3, and the arrangement of the third cavity 1033 facilitates the communication between the first detection chamber 301 and the inhalation chamber 100.

[0045] The first air passage 1021 is provided corresponding to the exhaust chamber 300 and is located in the middle of the end cover 102. Preferably, the first air passage 1021 is in the shape of a circular groove with the notch facing the fixed scroll 201. The second air passage 1022 is in the shape of an annulus provided along the circumference of the first air passage 1021. The third air passage 1023 is in the shape of an annulus provided along the outer periphery of the scroll assembly 2. The annular shape of the second air passage 1022 facilitates improved communication with the intermediate chamber 200, while the annular shape of the third air passage 1023 facilitates communication between the first detection chamber 301 and the suction chamber 100, and is convenient for arrangement and implementation.

[0046] like Figure 1 As shown in , the second air duct 1022 is arranged along the circumference of the first air duct 1021, and the third air duct 1023 is arranged along the circumference of the second air duct 1022. The second air duct 1022 is arranged corresponding to the two intermediate cavities 200, and the third air duct 1023 is arranged corresponding to the two suction cavities 100. The three air ducts are arranged radially from the inside to the outside of the end cover 102, and the fixed scroll 201 and the end cover 102 are installed. The air ducts can be blocked, thereby ensuring the connection effect. Of course, a solution in which either the second air duct 1022 or the third air duct 1023 is annular is also feasible.

[0047] like Figure 1 and Figure 2 As shown in FIG, the control valve 3 is provided with several seals, which separate the installation cavity 103 into a first cavity 1031 communicating with the inlet of the control valve 3 and a second cavity 1032 communicating with the outlet of the control valve 3. The first air passage 1021 communicates with the inlet of the control valve 3 through the first cavity 1031, and the second air passage 1022 communicates with the outlet of the control valve 3 through the second cavity 1032. The arrangement of the first cavity 1031 and the second cavity 1032 facilitates the flow of gas through the control valve 3, not only facilitating the control valve 3 to control the reflux flow of gas, but also facilitating the reflux of gas.

[0048] Specifically, the mounting cavity 103 is provided on the end cap 102, with a gap between the outer periphery of the control valve 3 and the inner wall of the mounting cavity 103. The sealing member includes a first sealing ring 306 provided between the middle portion of the control valve 3 and the inner wall of the mounting cavity 103, and a second sealing ring provided between the bottom of the control valve 3 and the inner wall of the mounting cavity 103. The second sealing ring is spaced apart from the bottom of the mounting cavity 103, with the first cavity 1031 located at the bottom of the second sealing ring, and the second cavity 1032 located between the first sealing ring 306 and the second sealing ring.

[0049] In this embodiment, part of the gas in the exhaust chamber 300 can first flow into the first chamber 1031, then into the inlet of the flow control valve 3, and then flow out through the outlet of the control valve 3 and into the second chamber 1032, and finally flow back to the middle chamber 200 through the second chamber 1032, thereby increasing the temperature of the gas in the middle chamber 200. The arrangement of the first chamber 1031 and the second chamber 1032 here is not only convenient for implementation, but also facilitates the backflow of gas.

[0050] In addition, the control valve 3 is equipped with several seals that define the installation chamber 103 into a third cavity 1033 that connects the first detection chamber 301 and the third air passage 1023. For ease of description, the seals herein include a third sealing ring 305 disposed between the top of the control valve 3 and the inner wall of the installation chamber 103. The third cavity 1033 is specifically located between the first sealing ring 306 and the third sealing ring 305. This helps ensure that there is no connection between the first detection chamber 301 and the exhaust chamber 300. The gas parameters in the first detection chamber 301 are closer to those in the exhaust chamber 300, thereby achieving better detection accuracy.

[0051] As a preferred embodiment, the scroll assembly 2 is provided with a first communication port communicating with the suction chamber 100, through which the first detection chamber 301 communicates with the suction chamber 100. In a specific embodiment, the first communication port is specifically provided on the fixed scroll 201, close to the first detection chamber 301. The third air duct 1023 connects between the third cavity 1033 and the first communication port, allowing gas in the suction chamber 100 to flow into the third air duct 1023 through the first communication port, and then into the third cavity 1033.

[0052] To facilitate the smooth flow of gas from the third cavity 1033 into the first detection cavity 301, a first connecting channel 3011 is provided on the valve seat, connecting the third cavity 1033 and the first detection cavity 301. Gas from the third cavity 1033 flows into the first detection cavity 301 via the first connecting channel 3011. At this point, the pressure detected by the first detection unit approximates the pressure within the suction cavity 100, thereby facilitating the acquisition of the suction cavity 100 pressure value. Furthermore, the first detection unit can be electrically connected to the connector 303 on the control valve 3 via a wiring harness, allowing both to share a single connector 303. Compared to the traditional solution of placing the first detection unit at the suction port, this shortens the wiring harness and improves the integration of the compressor.

[0053] As another embodiment, Figure 1 and Figure 2As shown in , a communication channel is provided between the outer periphery of the scroll assembly 2 and the housing 1. The communication channel connects between the accommodating chamber and the first detection chamber 301. The first detection chamber 301 communicates with the air inlet of the suction chamber 100 through the accommodating chamber. For ease of distinction, the communication channel herein is referred to as the second communication channel 105. The provision of the second communication channel 105 enables the first detection chamber 301 to communicate with the air inlet of the suction chamber 100 through the accommodating chamber, and also facilitates the communication between the first detection chamber 301 and the suction chamber 100. To improve the communication effect, a plurality of second communication channels 105 are arranged at intervals along the circumference of the scroll assembly 2, which helps to improve the efficiency of gas inflow.

[0054] In this embodiment, the gas in the accommodating chamber can flow into the third air duct 1023, the third cavity 1033, the first connecting channel 3011 in sequence through the second connecting channel 105, and then into the first detection chamber 301, so that the pressure parameters in the first detection chamber 301 are closer to those in the inhalation chamber 100, which is beneficial to improving the detection accuracy of the first detection part.

[0055] In addition, the scroll assembly 2 has two intermediate cavities 200 disposed opposite each other, and second communication ports 204 connecting each intermediate cavity 200 with the second air duct 1022. The second communication ports 204 on the two intermediate cavities 200 are disposed opposite each other. Each intermediate cavity 200 is connected to the second air duct 1022 through two oppositely disposed second communication ports 204, which helps to improve the gas recirculation effect.

[0056] When implementing it specifically, Figure 3 As shown in , each intermediate cavity 200 can be connected to the third air duct 1023 via one or two second connecting ports 204. The second connecting port 204 can be located between the two spiral sheets forming the intermediate cavity 200, or can be arranged near the side of one of the spiral sheets. In addition to being circular, the second connecting port 204 can also be in an elongated shape, as long as the ventilation requirements are met. A third connecting port 203 for connecting the exhaust cavity 300 with the first air duct 1021 is also provided on the static vortex 201, so as to facilitate part of the gas in the exhaust cavity 300 to flow into the first air duct 1021 and to be able to flow back to the intermediate cavity 200.

[0057] To further enhance the compressor's integration, in this embodiment, the control valve 3 is provided with a second detection chamber 302 communicating with the exhaust chamber 300. A second detection unit is located within the second detection chamber 302, capable of detecting at least the pressure in the exhaust chamber 300. The provision of the second detection chamber 302 communicating with the exhaust chamber 300 and the second detection unit facilitates exhaust pressure detection and provides a basis for the second detection unit and the control valve 3 to share a connector 303, thereby facilitating an integrated design.

[0058] In terms of specific structure, Figure 2As shown in , the second detection chamber 302 is provided on the valve stem of the control valve 3, and the valve stem is provided with an air inlet channel 3021 that is connected to the valve chamber of the control valve 3. The provision of the second detection chamber 302 on the valve stem and the provision of the air inlet channel 3021 facilitate the detection of the pressure of the exhaust chamber 300. The gas in the first cavity 1031 can flow into the valve chamber through the inlet of the control valve 3 and directly flow into the air inlet channel 3021 and the second detection chamber 302, so that the gas parameters in the second detection chamber 302 are closer to those in the exhaust chamber 300, thereby facilitating the improvement of the accuracy of the second detection unit. In specific implementation, the second detection unit can also be electrically connected to the connector 303 on the control valve 3 via a wiring harness, enabling the sharing of the connector 303, thereby facilitating the improvement of the integrated layout of the compressor.

[0059] It should be noted that the structure of the control valve 3 in this embodiment and the movement of its valve stem can be similar to conventional solenoid valves. For example, the control valve 3 includes a control coil for controlling the movement of the valve stem. Adjusting the position of the valve stem changes the flow area and, consequently, the gas flow rate. The connector 303 on the control valve 3 is electrically connected to the controller in the control box 104 to receive control signals from the controller and regulate the flow rate of gas returning to the intermediate chamber 200.

[0060] In this embodiment, at least one of the first and second detection units includes a temperature and pressure sensor. This temperature and pressure sensor can detect not only pressure parameters but also temperature parameters, and has good detection accuracy. Of course, the detection unit can also be a pressure sensor, in which case it can only detect pressure values. In specific implementations, the detection unit can be determined based on usage requirements.

[0061] In this embodiment, the first detection part and the second detection part can be electrically connected to the connector 303 on the control valve 3, so that they can be directly controlled by the controller of the compressor. That is, the signal processing circuit, amplification circuit, power supply and other circuits of the detection part are in the compressor controller, which helps to shorten the length of the wiring harness, and is more convenient for the compressor diversion control and the exhaust pressure and exhaust temperature control, thereby helping to ensure the performance of the compressor.

[0062] In addition, if Figure 1 As shown in FIG, a filter unit 304 for filtering gas is provided at the inlet of the control valve 3. This helps to improve the cleanliness of the gas and prevent foreign matter from entering the control valve 3 and causing it to become unusable. In the specific arrangement, the filter unit 304 can adopt a structure with a filtering effect such as a filter mesh, as long as it meets the use requirements.

[0063] The compressor of this embodiment allows a portion of the airflow in the exhaust chamber 300 to flow back to the intermediate chamber 200 via the control valve 3. Compared to conventional solutions that require a bypass circuit between the exhaust chamber 300 and the gas-liquid separator, this reduces the use of piping and connectors, thereby lowering costs and minimizing heat and pressure losses. Furthermore, the control valve 3 and the two detection units share a single connector 303, which is directly connected to the compressor controller. This facilitates installation and shortens wiring, facilitating compressor flow diversion control and controlling exhaust pressure and temperature, resulting in improved control effectiveness.

[0064] In addition, this embodiment also relates to a thermal management system, in which the compressor described above is provided. The thermal management system herein can be configured on a vehicle to adjust the temperature inside the vehicle.

[0065] The thermal management system described in this embodiment, by providing the above-mentioned compressor, is conducive to increasing the temperature of the compressor exhaust port in winter, thereby improving the performance of the thermal management system.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
