It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. This achieves the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).
[0003] The thermal management integrated module mainly refers to the integration of the compressor with heat exchangers, flow channels, electronic expansion valves, and liquid receivers. In existing technologies, the compressor's suction port, discharge port, and the two heat exchangers are located on different sides of the compressor.

[0038] Example 1
[0039] This embodiment provides a thermal management integrated module to eliminate the need for external piping, resulting in a clean, refined, compact, and highly integrated thermal management integrated module.
[0040] Specifically, such as Figures 1 to 3As shown, this embodiment provides a thermal management integrated module that is compatible with all types of refrigerants and maintains the refrigerant charge within 150g. The thermal management integrated module includes a compressor 1, a first heat exchanger 2, a second heat exchanger 3, and a make-up gas heat exchanger 8. The compressor 1 is provided with an intake channel, an exhaust channel, and a make-up gas channel. The intake channel has an intake port 11, the exhaust channel has an exhaust port 12, and the make-up gas channel has a make-up gas port 13, so that the intake channel, exhaust channel, and make-up gas channel are integrated with the compressor 1. The first heat exchanger 2 is provided with an outlet, and the intake channel is connected to the outlet, so that the intake port 11 is connected to the outlet. The second heat exchanger 3 is provided with an inlet, and the exhaust channel is connected to the inlet, so that the exhaust port 12 is connected to the inlet. The make-up gas heat exchanger 8 is provided with a second outlet, and the make-up gas channel is connected to the second outlet, so that the make-up gas port 13 is connected to the second outlet. The intake channel connects to the outlet, connecting the intake port 11 to the outlet, eliminating the need for the connecting hose between the first heat exchanger 2 and the compressor 1, thus achieving a rigid connection between the outlet of the first heat exchanger 2 and the intake port 11 of the compressor 1. Similarly, the exhaust channel connects to the inlet, connecting the exhaust port 12 to the inlet, eliminating the need for the connecting hose between the second heat exchanger 3 and the compressor 1, thus achieving a rigid connection between the inlet of the second heat exchanger 3 and the exhaust port 12 of the compressor 1. Likewise, the make-up air channel connects to the second outlet, connecting the make-up air port 13 to the second outlet, eliminating the need for the connecting hose between the make-up air heat exchanger 8 and the compressor 1, thus achieving a rigid connection between the second outlet of the make-up air heat exchanger 8 and the make-up air port 13 of the compressor 1. The reduction in external connecting hoses greatly simplifies the assembly process of the compressor 1 with the first heat exchanger 2, the second heat exchanger 3, and the make-up air heat exchanger 8, resulting in a neat, refined, compact, and highly integrated thermal management module, thereby reducing the overall size of the thermal management integrated module. The amount of refrigerant remaining in the pipeline decreases as the number of external pipelines decreases, thereby achieving precise control over the refrigerant charge and ensuring that the refrigerant charge remains below 150g. A gas-replenishing heat exchanger 8 is installed in the thermal management integrated module to ensure compatibility with all refrigerants. In this embodiment, the first heat exchanger 2 is a water-cooled evaporator, and the second heat exchanger 3 is a water-cooled condenser.
[0041] The outlet and intake port 11 of the first heat exchanger 2 are connected via a mechanical structure, eliminating the need for hose connections. This eliminates the need for piping around the compressor 1, allowing the intake port flow channel to be directly integrated with the compressor design. Similarly, the exhaust port 12 and the make-up air port flow channel can also be integrated with the compressor, making the thermal management integrated module a single unit. This results in a compact and streamlined appearance, easy installation, and lightweight design, making it more suitable for various environmental requirements. Furthermore, the direct connection between the outlet and intake port 11 of the first heat exchanger 2 resolves the tolerance issues in the connection between the first heat exchanger 2 and the compressor 1. This eliminates the need for precise alignment or adjustment of connecting parts during product assembly, greatly simplifying the assembly process, improving production efficiency, and reducing the production cost of the thermal management integrated module. It also reduces potential assembly errors between the first heat exchanger 2 and the compressor 1, enhancing the appearance and optimizing the production process. Similarly, the direct connection between the inlet and exhaust port 12 of the second heat exchanger 3 resolves the connection tolerance issues between the second heat exchanger 3 and the compressor 1, further improving production efficiency. The direct connection between the second outlet of the gas replenishment heat exchanger 8 and the gas replenishment port 13 solves the connection tolerance problem between the gas replenishment heat exchanger 8 and the compressor 1, improves production efficiency, and achieves the effect of enhancing the appearance and texture of the thermal management integrated module and optimizing the production process.
[0042] Optionally, such as Figure 2 As shown, the intake port 11, exhaust port 12, and make-up air port 13 are located in the first part 103 of the compressor 1 to achieve a high degree of integration of the thermal management integrated module. In other embodiments, the intake port 11, exhaust port 12, and make-up air port 13 can be adjusted through the intake flow channel, exhaust flow channel, and make-up air flow channel, and are concentrated in the second part 104 or the third part 105 of the compressor 1.
[0043] Furthermore, such as Figure 3 As shown, the thermal management integrated module also includes a flow channel plate 4, which has a first connection port and a second connection port. The inlet of the first heat exchanger 2 is connected to the first connection port, and the outlet of the second heat exchanger 3 is connected to the second connection port. By connecting the first heat exchanger 2 and the second heat exchanger 3 to the flow channel plate 4 respectively, the flow channel plate 4 can guide the coolant to flow throughout the integrated module.
[0044] Furthermore, the intake port 11, exhaust port 12, make-up air port 13, and flow channel plate 4 are located on the same side of the compressor 1, thereby making the first heat exchanger 2, the second heat exchanger 3, the make-up air heat exchanger 8, and the flow channel plate 4 all located on the same side of the compressor 1. This facilitates the connection between the inlet of the first heat exchanger 2 and the first connection port. Compared to setting the first heat exchanger 2 and the flow channel plate 4 on opposite sides of the compressor 1, the solution provided in this embodiment reduces the pipes connecting the first heat exchanger 2 and the flow channel plate 4. Moreover, this structural design facilitates the connection between the outlet of the second heat exchanger 3 and the second connection port. Compared to setting the second heat exchanger 3 and the flow channel plate 4 on opposite sides of the compressor 1, the solution provided in this embodiment reduces the pipes connecting the second heat exchanger 3 and the flow channel plate 4, thereby achieving the effect of reducing the external pipes between the flow channel plate 4 and the first heat exchanger 2 and the second heat exchanger 3.
[0045] Optionally, such as Figure 3 As shown, the thermal management integrated module also includes a liquid receiver 5. The inlet of the liquid receiver 5 is connected to the exhaust port 12, and the outlet of the liquid receiver 5 is connected to the suction port 11. The load on the compressor 1 changes continuously during operation. When the heat load of the water-cooled evaporator is high, more refrigerant is needed for evaporation and heat absorption; when the load is low, less refrigerant is required. The liquid receiver 5 can store excess refrigerant and adjust the refrigerant supply when the load changes, ensuring that the water-cooled evaporator always receives the appropriate amount of refrigerant, thus guaranteeing the stable operation of the compressor 1.
[0046] Furthermore, the flow channel plate 4 is also provided with a third connection port and a fourth connection port. The inlet of the liquid storage tank 5 is connected to the third connection port, and the outlet of the liquid storage tank 5 is connected to the fourth connection port, thereby connecting the liquid storage tank 5 and the flow channel plate 4. The flow channel plate 4 is provided with a first flow channel and a second flow channel. The first flow channel connects the first connection port and the fourth connection port, and the second flow channel connects the second connection port and the third connection port. Moreover, the first flow channel and the second flow channel within the flow channel plate 4 are independent of each other.
[0047] Furthermore, the thermal management integrated module also includes a gas-liquid separator. A cavity 31 is provided within the first heat exchanger 2 and the second heat exchanger 3. Both the liquid storage tank 5 and the gas-liquid separator are located within the cavity 31, resulting in a neat, refined, compact, and highly integrated thermal management integrated module, thereby reducing its size. In other embodiments, a cavity 31 can also be provided within the first heat exchanger 2 or the second heat exchanger 3, with the liquid storage tank 5 placed within the cavity 31 and the gas-liquid separator positioned on the flow channel plate 4. In yet another embodiment, a cavity 31 can also be provided within the first heat exchanger 2 or the second heat exchanger 3, with the gas-liquid separator placed within the cavity 31 and the liquid storage tank 5 positioned on the flow channel plate 4.
[0048] Optionally, such as Figures 3 to 4As shown, the thermal management integrated module also includes a control system, which includes a first control valve 61 and a second control valve 62 to regulate the refrigerant supply. The inlet of the first heat exchanger 2 is connected to the first connection port through the first control valve 61 to control and regulate the refrigerant flow rate within the first heat exchanger 2. The outlet of the first heat exchanger 2 is connected to the suction port 11 through the second control valve 62 to control and regulate the refrigerant flow rate within the compressor 1. In this embodiment, both the first control valve 61 and the second control valve 62 are electronic expansion valves 9. In other embodiments, both the first control valve 61 and the second control valve 62 are throttling valves.
[0049] Optionally, the first heat exchanger 2 and the second heat exchanger 3 are arranged vertically to reduce the floor space required. In other embodiments, the first heat exchanger 2 and the second heat exchanger 3 may also be arranged horizontally.
[0050] Optionally, a gap is left between the first heat exchanger 2, the second heat exchanger 3 and the compressor 1, and the flow channel plate 4 is set in the gap, which improves the space utilization of the thermal management module as a whole, improves the integration of the first heat exchanger 2, the second heat exchanger 3, the compressor 1 and the flow channel plate 4, and further reduces the volume of the thermal management integrated module.
[0051] Furthermore, one sidewall of the flow channel plate 4 is connected to the compressor 1, and the other sidewall of the flow channel plate 4 is connected to the first heat exchanger 2 and the second heat exchanger 3, thereby realizing the connection of the first heat exchanger 2, the second heat exchanger 3, the flow channel plate 4, and the compressor 1. In this embodiment, the flow channel plate 4 and the compressor 1 are connected by bolts. In other embodiments, the flow channel plate 4 and the compressor 1 can also be clamped together by a clamping structure.
[0052] Optionally, the thermal management integrated module further includes a first detection unit 71, a second detection unit 72, and a third detection unit 73. The first detection unit 71 can detect the temperature and pressure inside the first heat exchanger 2; the second detection unit 72 can detect the temperature and pressure inside the second heat exchanger 3; and the third detection unit 73 can detect the temperature and pressure at the suction port 11. By setting the first detection unit 71, the second detection unit 72, and the third detection unit 73, the temperature and pressure of the refrigerant inside the first heat exchanger 2 and the second heat exchanger 3, as well as at the suction port 11, are detected in the thermal management integrated module. Based on the pressure and temperature data detected by the first detection unit 71, the second detection unit 72, and the third detection unit 73, the opening degree of the first control valve 61 and the second control valve 62, as well as the speed of the compressor 1, are controlled to achieve precise regulation. It should be noted that the above-mentioned control method for controlling the opening degree of the first control valve 61 and the second control valve 62 based on pressure and temperature data, and the control method for controlling the speed of the compressor 1, are existing technologies in the art. For example, the control system also includes a controller, in which a preset maximum pressure value of the first heat exchanger 2 is input in advance. When the first detection unit 71 detects that the pressure inside the first heat exchanger 2 is equal to or exceeds the preset maximum pressure value, the controller controls the first control valve 61 to reduce the opening degree, so as to reduce the pressure of the first heat exchanger 2.
[0053] In this embodiment, the first detection unit 71, the second detection unit 72, and the third detection unit 73 are all temperature and pressure sensors. In other embodiments, the first detection unit 71, the second detection unit 72, and the third detection unit 73 each include a temperature and pressure sensor and a pressure sensor.
[0054] Optionally, such as Figure 4As shown, the thermal management integrated module also includes a high-pressure charging port 101 and a low-pressure charging port 102. The high-pressure charging port 101 is located on the flow channel plate 4, which also includes a third flow channel. The third flow channel is not connected to the first and second flow channels, but is connected to the high-pressure charging port 101. The exhaust port 12 is connected to the inlet of the second heat exchanger 3 through the third flow channel. Charging refrigerant through the high-pressure charging port 101 helps to replenish the high-pressure part of the refrigeration cycle when the system is under maintenance or the refrigerant is insufficient, so that the compressor 1 can work normally and efficiently. A low-pressure charging port 102 is installed on the compressor 1. The compressor 1 has a first intake passage and a second intake passage, both of which are connected to the compression chamber of the compressor 1. The first intake passage is connected to the suction port 11, and the second intake passage is connected to the low-pressure charging port 102. Both the suction port 11 and the low-pressure charging port 102 are connected to the outlet of the first heat exchanger 2. The low-pressure charging port 102 is used for two purposes: First, it is used to add refrigerant. When the refrigerant in the compressor 1 is insufficient, it is replenished through the low-pressure charging port 102. After the gaseous refrigerant enters the compressor 1, it smoothly participates in subsequent evaporation and heat absorption processes, thereby ensuring the cooling effect of the compressor 1. Second, it is used for the system vacuuming operation. After installing or repairing the compressor 1, a vacuum pump is connected through the low-pressure charging port 102 to extract the air and moisture inside the compressor 1, preventing non-condensable gases such as air from affecting the cooling performance of the compressor 1, ensuring that the compressor 1 operates normally under vacuum, and extending the service life of the compressor 1.
[0055] Furthermore, such as Figures 5 to 6 As shown, the thermal management integrated module also includes an expansion valve 9. The first inlet of the make-up gas heat exchanger 8 is connected to the exhaust port 12, the first outlet of the make-up gas heat exchanger 8 is connected to the inlet of the first heat exchanger 2, the second inlet of the make-up gas heat exchanger 8 is connected to the first outlet of the make-up gas heat exchanger 8 through the expansion valve 9, and the second outlet of the make-up gas heat exchanger 8 is connected to the suction port 11. By setting up the make-up gas heat exchanger 8, on the one hand, the hot gas bypass function of the thermal management integrated module is realized, thereby improving the heating capacity in the heating mode; on the other hand, the make-up gas entering the system through the liquid storage tank 5 is cooled or heated to regulate the make-up gas and achieve efficient operation of the compressor 1 refrigeration cycle.
[0056] Furthermore, both the gas-injection heat exchanger 8 and the expansion valve 9 are mounted on the flow channel plate 4 to achieve a high degree of integration of the thermal management module. In this embodiment, the gas-injection heat exchanger 8 and the expansion valve 9 are located on the same side of the flow channel plate 4. In other embodiments, the gas-injection heat exchanger 8 and the expansion valve 9 may be located on opposite sides or adjacent sides of the flow channel plate 4, depending on the actual situation.
[0057] like Figure 6As shown, when compressor 1 is working, refrigerant is discharged from the exhaust port 12 of compressor 1 and enters the water-cooled condenser. In the water-cooled condenser, the refrigerant exchanges heat with the coolant. After heat exchange, the refrigerant flows out of the water-cooled condenser, enters the flow channel plate 4 through the second connection port, and flows into the liquid storage tank 5 through the flow channel plate 4. The liquid refrigerant flows out of the liquid storage tank 5, passes through the flow channel plate 4, and enters the make-up gas heat exchanger 8 through the first inlet. From the first outlet of the make-up gas heat exchanger 8, it splits into two paths. One path flows through the flow channel plate 4 into the first control valve 61. The gas-liquid mixed refrigerant passing through the first control valve 61 enters the water-cooled evaporator. Inside the water-cooled evaporator, the refrigerant exchanges heat with the coolant. After heat exchange, the gaseous refrigerant flows out of the water-cooled evaporator and enters compressor 1. Compressor 1 works, compressing the low-pressure gaseous refrigerant into a high-pressure gaseous refrigerant, which is then discharged from the exhaust port 12, thus completing one working cycle. The other path of refrigerant flowing out from the first outlet of the gas-fuel heat exchanger 8 returns to the gas-fuel heat exchanger 8 through the expansion valve 9. Inside the gas-fuel heat exchanger 8, the two refrigerants exchange heat and then flow out from the second outlet of the gas-fuel heat exchanger 8, enter the compressor 1 through the suction port 11. The compressor 1 works to compress the gaseous refrigerant into high-pressure gas, and then discharges it from the exhaust port 12, thus completing a small working cycle and ultimately achieving the optimal thermal management goal.
[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
