[0011] In one embodiment of this disclosure, the compressor further includes a temperature sensing component disposed on the compressor body, the temperature sensing component being used to detect the temperature of the fluid flowing into the air inlet and to send a temperature signal to the control component; The control component is used to receive the temperature signal and compare the value of the temperature signal with a first preset value; When the value of the temperature signal is less than or equal to the first preset value, the control component controls the heating element to turn on; When the value of the temperature signal is greater than the first preset value, the control component controls the heating element to turn off.
[0012] According to a second aspect of this disclosure, a thermal management system is provided, comprising a condenser, an expansion valve, an evaporator, and a compressor as described in any of the above embodiments, connected in sequence.
[0013] In one embodiment of this disclosure, the evaporator has a separated first chamber and a second chamber, the second chamber being in communication with an air inlet. The thermal management system further includes a water circulation module, which includes a circulation pump, and the inner cavity of the circulation pump is connected to the first chamber.
[0014] In one embodiment of this disclosure, the thermal management system further includes a temperature detection component and a control module.

In the embodiments of this disclosure, the fluid heated by the heating element directly enters the compressor body for compression, shortening the path of the fluid from the heating element to the compressor body, reducing heat loss of the fluid heated by the heating element, and increasing the heating rate of the fluid, thereby improving the compression efficiency of the compressor. In addition, in low-temperature environments, since the fluid is heated before flowing into the air inlet, and then compressed by the compressor body, the load and power consumption of the compressor body can be reduced, and the service life of the compressor body can be increased.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.
[0027] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.
[0028] This disclosure provides a compressor 1. See also Figures 1-4The compressor 1 includes a compressor body 11, a heating assembly 12, and a control assembly 13. The compressor body 11 has an inlet 111 and an outlet 112. The heating assembly 12 is located at the inlet 111 and includes a heating housing 121 and a heating element 122. The heating housing 121 has an inlet 1213 and at least one outlet 1214, which communicates with the inlet 111. The heating element 122 is located within the heating housing 121 and between the inlet 1213 and the outlet 1214. Fluid flowing in from the inlet 1213 is heated by the heating element 122 and then flows out from the outlet 1214. The control assembly 13 is located in the heating housing 121 and is used to control the opening and closing of the compressor body 11 and the heating element 122.
[0029] Thus, by providing a heating element 12 at the air inlet 111 of the compressor body 11 and controlling the compressor body 11 to start with the heating element 122 via the control element 13, fluid can enter the heating housing 121 from the air inlet 1213. After being heated by the heating element 122, the heated fluid can flow into the air inlet 111 through the air outlet 1214, and finally be compressed by the compressor body 11 and discharged from the air outlet 112. In the embodiments of this disclosure, the fluid heated by the heating element 122 directly enters the compressor body 11 for compression, shortening the path of the fluid from the heating element 122 to the compressor body 11, reducing the heat loss of the fluid heated by the heating element 122, and increasing the heating rate of the fluid, thereby improving the compression efficiency of the compressor 1. Furthermore, in low-temperature environments (e.g., -20°C), since the fluid is heated before flowing into the air inlet 111 and then compressed by the compressor body 11, the load and power consumption of the compressor body 11 can be reduced, and the service life of the compressor body 11 can be improved.
[0030] In one embodiment of this disclosure, the fluid may be a refrigerant. For example, the refrigerant may be a refrigeration-grade propane (R290), tetrafluoroethane (R-134a), or tetrafluoropropylene (R1234yf), etc.
[0031] In one embodiment of this disclosure, see Figures 1-4 The compressor body 11 may include a casing, a motor, a moving scroll plate, and a stationary scroll plate. An inlet 111 and an outlet 112 are located within the casing, which is connected to a heating housing 121, allowing the inlet 111 to communicate with an outlet 1214. The outlet 112 is located at the end of the casing furthest from the heating housing 121. The motor, moving scroll plate, and stationary scroll plate are housed within the casing. The moving and stationary scroll plates mesh with each other to form multiple compression chambers. The motor's output shaft is coaxially connected to the moving scroll plate, enabling the motor to drive the moving scroll plate to rotate, thereby changing the volume of the multiple compression chambers to facilitate fluid intake, compression, and discharge.
[0032] It should be noted that, in this disclosure, the connection methods include, but are not limited to, welding, bolting, bonding, threaded connection, snap-fit, and integral connection.
[0033] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 The heating housing 121 includes a mounting plate 1211 and a side plate 1212 surrounding the mounting plate 1211. An air inlet 1213 is located on the side plate 1212. The mounting plate 1211 and the side plate 1212 form a receiving cavity for the heating housing 121. An air outlet 1214 is located on the mounting plate 1211. There can be multiple air outlets 1214, which can be arranged in an array on the mounting plate 1211. A heating element 122 is located on the side of the mounting plate 1211 near the side plate 1212 and within the receiving cavity. One end of the housing has an air inlet 111 connected to the mounting plate 1211. A control component 13 is located on the side of the side plate 1212 away from the mounting plate 1211 and is used to seal the heating housing 121. Thus, the mounting plate 1211 and the side plate 1212 can form a receiving cavity, in which the heating element 122 can be disposed. The control assembly 13 can seal the receiving cavity to improve the sealing performance of the heating housing 121. In addition, since the control assembly 13 seals the receiving cavity, there is no need to provide an additional end cap for sealing the receiving cavity, which helps to reduce the size of the compressor 1 and facilitates the high integration of the compressor 1.
[0034] In one embodiment of this disclosure, the heating housing 121 may be cylindrical, prismatic, ellipsoidal, or irregularly shaped, depending on specific requirements, and is not limited herein.
[0035] In one embodiment of this disclosure, the side plate 1212 may have a first protrusion, and an air inlet 1213 is provided on the first protrusion and communicates with the receiving cavity, so as to connect the compressor 1 with other devices through the first protrusion and realize the introduction of fluid into the compressor 1.
[0036] In one embodiment of this disclosure, the housing may have a second protrusion, and the air outlet 112 is located on the second protrusion and communicates with the inner cavity of the housing, so as to connect the compressor 1 to other devices through the second protrusion and realize the discharge of fluid from the compressor 1.
[0037] In one embodiment of this disclosure, see Figure 3The heating element 122 includes a heating wire 1221 and a thermally conductive insulating layer 1222 disposed on the heating wire 1221. The heating wire 1221 extends along a curved or zigzag trajectory on the mounting plate 1211. Thus, the thermally conductive insulating layer protects the heating wire 1221 and isolates the electrical connection between the heating wire 1221 and the heating housing 121, preventing leakage from the heating housing 121. Furthermore, extending the heating wire 1221 along a curved or zigzag trajectory increases its length on the mounting plate 1211, improving heating efficiency. For example, the heating wire 1221 extends along a curved trajectory on the mounting plate 1211; the curve can be an S-shaped curve, a Z-shaped curve, a planar spiral curve, or other irregularly shaped curves. Further, the heating wire 1221 may include multiple straight segments and multiple arc-shaped segments. The multiple straight segments are parallel to each other, and adjacent straight segments are connected by an arc-shaped segment to form a heating wire 1221 extending reciprocally along an S-shaped trajectory.
[0038] In one embodiment of this disclosure, see Figure 2 The control assembly 13 includes a control housing 131 and a controller disposed within the control housing 131. The control housing 131 is connected to the side plate 1212 away from the mounting plate 1211 and can seal the heating housing 121. The controller is used to control the opening and closing of the compressor body 11 and the heating element 122. Thus, the opening and closing of the heating element 122 and the motor can be controlled by a single controller, eliminating the need for an additional controller to control the opening and closing of the heating element 122. This facilitates the high integration of the control assembly 13 and reduces the size of the compressor 1. The control housing 131 can seal the receiving cavity of the heating housing 121, eliminating the need for an additional end cap for sealing the receiving cavity, further contributing to the reduction of the compressor 1's size.
[0039] In one embodiment of this disclosure, the controller may include a circuit board and a filter circuit, a microprocessor, and power devices disposed on the circuit board. The filter circuit may include electronic components such as capacitors, inductors, and resistors to filter the signals sent and received by the controller, thereby improving the stability and accuracy of the signals. The microprocessor may receive or send signals to control the operation of the heating element 122 and the motor. The power devices may be insulated-gate bipolar transistors (IGBTs) or insulated-gate field-effect transistors (MOS). This facilitates the control of the heating element 122 and the motor.
[0040] In one embodiment of this disclosure, see Figure 2 , Figure 3The heating assembly 12 also includes a connector 123, which is mounted on the mounting plate 1211. The controller is electrically connected to the heating element 122 and the motor of the compressor body 11 via the connector 123. For example, the connector 123 can be a busbar. One end of the connector 123 can be soldered to the controller using selective wave soldering, and the other end can be soldered to the heating element 122 using reflow soldering. The mounting plate 1211 has clearance holes for the connector 123 to pass through, and the clearance holes communicate with the receiving cavity to facilitate the controller's control of the heating element 122. Of course, the connector 123 can also be a flexible busbar or a closed busbar. In this way, the controller can be electrically connected to the heating element 122 and the motor via a single connector 123, further reducing the size of the compressor 1.
[0041] In one embodiment of this disclosure, see Figure 2 , Figure 3 , Figure 4 The mounting plate 1211 has multiple positioning blocks 1215 on the side away from the compressor body 11. The multiple positioning blocks 1215 can be arranged at intervals along a straight trajectory, and part of the heating wire 1221 is clamped between two adjacent positioning blocks 1215. In this way, the multiple positioning blocks 1215 facilitate the positioning and installation of the heating wire 1221 on the mounting plate 1211.
[0042] In one embodiment of this disclosure, see Figure 4 The positioning block 1215 is staggered from the air outlet 1214, meaning that the positioning block 1215 will not block the air outlet 1214, and the heating wire 1221 will not block the air outlet 1214, so that the fluid can flow out of the receiving cavity of the heating shell 121 from the air outlet 1214.
[0043] In one embodiment of this disclosure, see Figure 1 , Figure 2The compressor 1 also includes a temperature sensing component 14 disposed on the compressor body 11. The temperature sensing component 14 can be disposed at the air inlet 111 of the compressor body 11. For example, the temperature sensing component 14 can be a temperature sensor or a temperature sensor. The temperature sensing component 14 is used to detect the temperature of the fluid flowing into the air inlet 111 and send a temperature signal to the control component 13. The control component 13 is used to receive the temperature signal and compare the value of the temperature signal with a first preset value. When the value of the temperature signal is less than or equal to the first preset value, the control component 13 controls the heating element 122 to turn on; when the value of the temperature signal is greater than the first preset value, the control component 13 controls the heating element 122 to turn off. In this way, the temperature sensing component 14 can detect the fluid temperature at the air inlet 111, and the control component 13 compares the value of the temperature signal with the first preset value. When the value of the temperature signal is greater than the first preset value, the control component 13 controls the heating element 122 to turn off, preventing the operating temperature of the compressor body 11 and the heating element 122 from becoming too high, which is beneficial to improving the service life of the compressor 1.
[0044] In one embodiment of this disclosure, the air inlet 111 of the housing has a protrusion, and the temperature sensing component 14 may be located within the protrusion.
[0045] In one embodiment of this disclosure, the temperature sensing component 14 can collect the fluid temperature at the air inlet 111, and generate a result temperature value by subtracting this temperature value from the theoretical temperature value. The result temperature value is then sent as a temperature signal to the controller of the control component 13. Upon receiving the temperature signal, the controller compares the result temperature value with a first preset value. When the result temperature value is less than or equal to the first preset value, the controller controls the heating element 122 to turn on; when the result temperature value is greater than the first preset value, the controller controls the heating element 122 to turn off. The first preset value can be 5℃ to 10℃. For example, the first preset value can be 5℃, 6℃, 7℃, 8℃, 9℃, or 10℃. In other words, the result temperature value represents the superheat of the compressor 1.
[0046] This disclosure also provides a thermal management system, see [link to relevant documentation]. Figure 1 , Figure 5 The system includes a condenser 2, an expansion valve 3, an evaporator 4, and a compressor 1 according to any of the above embodiments, all connected sequentially by pipelines. Low-temperature, low-pressure gas enters the compressor 1 through the inlet 1213, is compressed by the compressor 1, and is discharged as high-temperature, stable-pressure gas from the outlet 112. After passing through the condenser 2 and expansion valve 3, it becomes low-temperature, low-pressure mist. After heat exchange in the evaporator 4, it becomes low-temperature, low-pressure gas again, and finally flows back to the compressor 1, thus forming a gas circulation path. This thermal management system possesses all the beneficial effects of the compressor 1 described above, which will not be elaborated upon here.
[0047] In one embodiment of this disclosure, the evaporator 4 has a separated first chamber and a second chamber, the second chamber being connected to an air inlet 1213 via a pipe. See also Figure 5 The thermal management system also includes a water circulation module 5, which includes a circulation pump 51. The inner cavity of the circulation pump 51 is connected to the first chamber via a pipeline. The first chamber may contain a heat exchange medium, which may be a liquid medium. Thus, by setting up the water circulation module 5, the circulation pump 51 introduces the heat exchange medium into the first chamber. The heat from the heat exchange medium can be transferred to the second chamber, causing the low-temperature, low-pressure mist in the second chamber to become low-temperature, low-pressure gas, which is then supplied to the compressor 1, enabling the normal operation of the entire thermal management system.
[0048] In one embodiment of this disclosure, the water circulation module 5 may further include a control valve disposed on the pipeline in order to control the opening and closing of the pipeline.
[0049] In one embodiment of this disclosure, see Figure 5The thermal management system further includes a temperature detection component 6 and a control module 7. The temperature detection component 6 is located in the evaporator 4 and is used to detect the temperature of the water flow in the first chamber and generate a detection signal. The temperature detection component 6 can be a temperature sensor or a temperature detector. The control module 7 receives the detection signal and compares the value of the detection signal with a second preset value, which can be -11℃ to -9℃. For example, the second preset value can be -11℃, -10℃, or -9℃. When the value of the detection signal is less than or equal to the second preset value, the control module 7 controls the circulation pump 51 to shut down and controls the control component 13 to turn on the heating element 122. When the value of the detection signal is greater than the second preset value, the control module 7 controls the control component 13 to shut down the heating element 122 and controls the circulation pump 51 to turn on. Thus, when the thermal management system starts up in a low-temperature environment, the temperature detection component 6 can detect the temperature of the water flow in the first chamber and generate a detection signal, which the control module 7 then compares with the second preset value. When the detected signal value is less than or equal to the second preset value, the water temperature in the second chamber is too low to heat the gas in the first chamber. Therefore, the control module 7 will control the circulation pump 51 to shut down and the control component 13 to turn on the heating element 122, so that the heating element 122 can heat the gas before it enters the compressor body 11. When the detected signal value is greater than the second preset value, the water temperature in the first chamber is higher than the gas temperature in the second chamber. Therefore, the water flow in the first chamber can heat the gas in the second chamber. The control module 7 can control the control component 13 to shut down the heating element 122 and turn on the circulation pump 51, which is beneficial for energy saving. In the embodiments of this disclosure, in low-temperature environments (e.g., -20°C), the low-temperature, low-pressure gas is heated by the heating element 122 and then compressed by the compressor body 11, which can reduce the load on the compressor body 11 and improve its service life.
[0050] Of course, when the value of the detection signal is greater than the second preset value, since the water temperature in the first chamber is higher than the gas temperature in the second chamber, the water flow in the first chamber can heat the gas in the second chamber. The control module 7 can control the control component 13 to turn on the heating element 122 and control the circulation pump 51 to turn on. The heating element 122 and the heat exchange medium in the first chamber work together to heat the low-temperature and low-pressure gas, which helps to improve the heating efficiency and thus reduce the load on the compressor body 11.
[0051] This disclosure also provides a vehicle, including a vehicle body and a thermal management system as described in any of the above embodiments, disposed on the vehicle body. This vehicle possesses all the beneficial effects of the aforementioned thermal management system, which will not be elaborated upon here. This vehicle can be a pure electric vehicle, a hybrid vehicle, or a conventional fuel vehicle, etc.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
