[0034] like Figures 1 to 11 The image shows an embodiment of the compressor in the integrated thermal management system provided by the present invention.
[0035] like Figures 1 to 4 As shown, the compressor of the integrated thermal management system in this embodiment includes a first heat exchanger 1, a second heat exchanger 2, and a compressor body 3. The first heat exchanger 1 and the second heat exchanger 2 are integrated and installed on the compressor body 3.
[0036] The first heat exchanger 1 and the second heat exchanger 2 supply heat exchange for refrigerant and water, respectively. The first heat exchanger 1 includes a first connection port 11 and a second connection port 12 that are connected to form a refrigerant channel. The second heat exchanger 2 includes a third connection port 21 and a fourth connection port 22 that are connected to form a refrigerant channel. The first heat exchanger 1 is connected to the compressor body 3 through the first connection port 11 and the second connection port 12, and the second heat exchanger 2 is connected to the compressor body 3 through the third connection port 21 and the fourth connection port 22, respectively, forming a refrigerant-side circulation loop. The first heat exchanger 1 also includes a first water-side interface 13 and a second water-side interface 14 that are connected to form a water channel. The second heat exchanger 2 also includes a third water-side interface 23 and a fourth water-side interface 24 that are connected to form a water channel. The first heat exchanger 1 is connected to the water-side system through the first water-side interface 13 and the second water-side interface 14, and the second heat exchanger 2 is connected to the water-side system through the third water-side interface 23 and the fourth water-side interface 24, respectively, forming a water-side circulation loop. The refrigerant on the compressor body 3 side and the water in the water-side system flow through the refrigerant channel and the water channel in the first heat exchanger 1 and the second heat exchanger 2 respectively and exchange heat.
[0037] The compressor body 3 includes a compressor housing 30, which has a first channel port 31, a second channel port 32, a third channel port 33, and a fourth channel port 34. The first channel port 31 is connected to and communicates with the first connection port 11 of the first heat exchanger 1, the second channel port 32 is connected to and communicates with the second connection port 12 of the first heat exchanger 1, the third channel port 33 is connected to and communicates with the third connection port 21 of the second heat exchanger 2, and the fourth channel port 34 is connected to and communicates with the fourth connection port 22 of the second heat exchanger 2.
[0038] The compressor housing 30 houses a compressor body 4 and a receiver chamber 5. The compressor body 4 includes a pump body 41, a motor 42, and a crankshaft 43 connecting the pump body 41 and the motor 42. The receiver chamber 5 has an outlet 50, which connects to the suction port 411 of the pump body 41, allowing refrigerant to be supplied from the receiver chamber 5 to the pump body 41 of the compressor body 4. The compressor housing 30 has a charging port 36 connected to the receiver chamber 5 for charging refrigerant into the receiver chamber 5, and a charging valve 37 connected to the charging port 36. The charging valve 37 charges the receiver chamber 5 with the refrigerant required for the refrigerant circulation loop. The receiver chamber 5 is integrated within the compressor housing 30, replacing the separately installed receiver component in the prior art to achieve the receiver function. The motor 42 drives the crankshaft 43 to rotate. The eccentric part of the crankshaft 43 drives the piston to rotate eccentrically within the pump body 41, compressing the low-temperature, low-pressure gaseous refrigerant sent from the receiver chamber 5 into the pump body 41 into a high-temperature, high-pressure gaseous refrigerant. The compressor body 4 is provided with a high-pressure exhaust port for discharging the high-temperature, high-pressure gaseous refrigerant compressed by the pump body 41.
[0039] The compressor housing 30 is also equipped with a first three-way valve 61, a second three-way valve 62, and an expansion valve 7. The first three-way valve 61 connects one of the first channel port 31 and the third channel port 33 to the liquid receiver chamber 5. The second three-way valve 62 connects the other of the first channel port 31 and the third channel port 33 to the high-pressure discharge port of the compressor body 4. The expansion valve 7 connects the second channel port 32 to the fourth channel port 34, thereby forming a refrigerant-side circulation loop. Both the first three-way valve 61 and the second three-way valve 62 have one connecting port and two interfaces. The connecting port of the first three-way valve 61 is connected to the liquid receiver chamber 5, and the two interfaces of the first three-way valve 61 are connected to the first channel port 31 and the third channel port 33, respectively. By switching the valve position of the first three-way valve 61, its connecting port is connected to one or the other of the two interfaces, thus connecting one or the other of the first channel port 31 and the third channel port 33 to the liquid receiver chamber 5. The connecting port of the second three-way valve 62 is connected to the high-pressure discharge port of the compressor body 4. The two ports of the second three-way valve 62 are respectively connected to the first channel port 31 and the third channel port 33. By switching the valve position of the second three-way valve 62, its connecting port can be connected to one or the other of the two ports, thus connecting one or the other of the first channel port 31 and the third channel port 33 to the high-pressure discharge port of the compressor body 4. By switching the valve positions of the first three-way valve 61 and the second three-way valve 62, the flow direction of the refrigerant discharged from the high-pressure discharge port of the compressor body 4 can be reversed in the first heat exchanger 1 and the second heat exchanger 2, achieving a refrigerant reversing cycle. In this embodiment, preferably, the first three-way valve 61 and the first channel port 31, the first three-way valve 61 and the third channel port 33, the first three-way valve 61 and the liquid storage chamber 5, the second three-way valve 62 and the first channel port 31, the second three-way valve 62 and the third channel port 33, the second three-way valve 62 and the high-pressure exhaust port of the compressor body 4, the expansion valve 7 and the second channel port 32, and the expansion valve 7 and the fourth channel port 34 are respectively connected through the housing flow channel 35 provided on the compressor housing 30.
[0040] The working principle of the compressor in the integrated thermal management system of this embodiment is as follows: When the first three-way valve 61 is in the position that connects the first channel port 31 to the liquid receiver cavity 5, and the second three-way valve 62 is in the position that connects the third channel port 33 to the high-pressure exhaust port of the compressor body 4, the low-temperature, low-pressure gaseous refrigerant in the liquid receiver cavity 5 enters the pump body 41 through the outlet port 50 of the liquid receiver 5 and the suction port 411 of the pump body 41. After being compressed into a high-temperature, high-pressure gaseous refrigerant in the pump body 41, it is discharged from the high-pressure exhaust port of the compressor body 4 and flows to the third channel port 41 through the second three-way valve 62. The refrigerant enters the second heat exchanger 2 through the third connection port 21 for heat exchange. After being cooled and liquefied into a medium-temperature, high-pressure liquid refrigerant, it exits from the fourth connection port 22 of the second heat exchanger 2 and enters the fourth channel port 34. After being depressurized by the expansion valve 7, it flows to the second channel port 32, thus entering the first heat exchanger 1 through the second connection port 12 for heat exchange. After absorbing heat and vaporizing into a low-temperature, low-pressure gaseous refrigerant, it exits from the first connection port 11 of the first heat exchanger 1 and enters the first channel port 31. It then flows to the liquid storage chamber 5 through the first three-way valve 61, forming a refrigerant circulation. During the refrigerant circulation, the first heat exchanger 1 and the second heat exchanger 2 simultaneously exchange heat with the water-side circulation loop. By switching the valve positions of the first three-way valve 61 and the second three-way valve 62, so that the first three-way valve 61 is in the position that connects the third channel port 33 to the liquid receiver chamber 5, and the second three-way valve 62 is in the position that connects the first channel port 31 to the high-pressure exhaust port of the compressor body 4, the refrigerant discharged from the high-pressure exhaust port of the compressor body 4 can flow in reverse in the first heat exchanger 1 and the second heat exchanger 2, thereby realizing the refrigerant reversal circulation.
[0041] The compressor of the integrated thermal management system in this embodiment has the advantage of high integration. The compressor body 3 has a built-in liquid receiver chamber 5 to realize the function of a liquid receiver. The first heat exchanger 1 and the second heat exchanger 2 are integrated and installed on the compressor body 3 to form a refrigerant-side circulation loop with the compressor body 3, which can meet the secondary loop requirements of propane refrigerant R290 and provide applications for full integration on the refrigerant side. The first heat exchanger 1 and the second heat exchanger 2 can be connected to a water-side system to form a water-side circulation loop. The secondary loop of the water-side system can ensure the safe application of propane refrigerant R290. The compressor of the integrated thermal management system in this embodiment is particularly suitable for automotive applications.
[0042] like Figure 4 , Figure 5 and Figure 8As shown, in this embodiment, preferably, the compressor housing 30 has an independent controller cavity 8 inside, and a controller 9 is installed in the controller cavity 8. The controller 9 is communicatively connected to the motor 42 of the compressor body 4. The controller 9 controls the start, stop, and operation of the motor 42 according to control commands, realizing intelligent control of the compressor's working cycle in the integrated thermal management system of this embodiment. The compressor body 3 also has a built-in liquid receiver cavity 5 and controller 9, further improving the integration level of the compressor in the integrated thermal management system of this embodiment.
[0043] In this embodiment, preferably, as follows: Figure 3 and Figure 4 As shown, the compressor housing 30 includes a main housing 301, an upper housing 302, a lower housing 303, and a controller housing 304. The upper housing 302, main housing 301, and lower housing 303 are connected sequentially from top to bottom to form an inner cavity. The upper and lower ends of the main housing 301 form openings, which are respectively closed by the upper housing 302 and the lower housing 303. A partition 305 is provided within the inner cavity formed by the three housings, dividing the inner cavity into an independent high-pressure chamber 306 and a low-pressure chamber. The pump body 41 and motor 42 of the compressor body 4 are installed in the high-pressure chamber 306. The high-pressure chamber 306, pump body 41, motor 42, and crankshaft 43 constitute the compressor body 4. The high-pressure chamber 306 has a high-pressure exhaust port, which serves as the high-pressure exhaust port of the compressor body 4. The high-temperature, high-pressure gaseous refrigerant compressed in the pump body 41 is discharged from the pump body 41 into the high-pressure chamber 306 and then discharged from the high-pressure exhaust port out of the compressor body 4. The low-pressure chamber serves as a liquid receiver chamber 5. The controller housing 304 is connected to the outside of the main housing 301 and together with the main housing 301 forms the controller cavity 8. This realizes the design of integrating the liquid reservoir cavity 5, the controller cavity 8 and the compressor body 4 into one unit.
[0044] Preferably, the reservoir chamber 5 and the motor 42 are located side-by-side above the pump body 41. For example... Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, the high-pressure chamber 306 extends vertically through the main housing 301 and is enclosed by the upper housing 302 and the lower housing 303.

The motor 42 is located in the vertical chamber 3061, the pump body 41 is located in the horizontal chamber 3062, and the reservoir chamber 5 is located on one side of the vertical chamber 3061 and above the horizontal chamber 3062, thus achieving a parallel arrangement of the reservoir chamber 5 and the motor 42 above the pump body 41. The upper end of the reservoir chamber 5 extends through the main housing 301 and is enclosed by the upper housing 302. The bottom of the reservoir chamber 5 is provided with an air outlet 50, and the pump body 41 is provided with an air intake 411 on the side below the reservoir chamber 5.

[0045] Preferably, such as Figure 4 and Figure 5 As shown, the controller cavity 8 is located on the side of the reservoir cavity 5 away from the vertical cavity 3061 of the high-pressure cavity 306. The controller cavity 8 can be formed on the outer side of the main housing 301 near the reservoir cavity 5 and enclosed by the controller housing 304.
[0046] Preferably, such as Figure 7 and Figure 8 As shown, the controller cavity 8 and the high-pressure cavity 306 are connected via a wiring hole 307 located on the main housing 301, which avoids the reservoir cavity 5. The controller 9 and the motor 42 are connected via a terminal 308 passing through the wiring hole 307. The terminal 308 is a three-phase terminal. This achieves electrical and communication connections between the controller 9 and the motor 42. The wiring hole 307 is located at the upper end of the main housing 301 near the motor 42, connecting the controller cavity 8 and the vertical cavity 3061 of the high-pressure cavity 306 where the motor 42 is located. The wiring hole 307 avoids the reservoir cavity 5, ensuring that the terminal 308 does not pass through the reservoir cavity 5, thus reducing the need for sealing.
[0047] In this embodiment, the controller housing 304 may be provided with high-pressure plug and low-pressure plug installation positions for connecting with the wiring harness plug of the application system (such as the vehicle system) of the integrated thermal management system compressor of this embodiment. Thus, the application system can send control commands to the controller 9 according to work needs to control the start, stop and operation of the motor 42, thereby realizing the working cycle of the integrated thermal management system compressor.
[0048] In this embodiment, the form of controller 9 is not limited, and conventional controllers such as PLC controllers or microcontrollers can be used.
[0049] like Figure 4 , Figures 9 to 11 As shown, in this embodiment, preferably, an upper recessed cavity 3021 is provided on the lower end surface of the upper housing 302. The upper recessed cavity 3021 is connected to the opening at the upper end of the main housing 301 through which the high-pressure cavity 306 passes, forming the upper end of the high-pressure cavity 306. A lower recessed cavity 3031 is provided on the upper end surface of the lower housing 303. The lower recessed cavity 3031 is connected to the opening at the lower end of the main housing 301 through which the high-pressure cavity 306 passes, forming the lower end of the high-pressure cavity 306.
[0050] In this embodiment, preferably, the upper housing 302, the lower housing 303, and the controller housing 304 are all fastened to the main housing 301 by bolts. Preferably, the first heat exchanger 1 and the second heat exchanger 2 are both fastened to the compressor housing 30 by bolts.
[0051] In this embodiment, the upper housing 302, the lower housing 303 and the controller housing 304 are all sealed and abutted against the main housing 301. The partition 305 is located inside the main housing 301, and the upper end of the partition 305 is sealed and abutted against the upper housing 302, thereby ensuring the independence and sealing of the liquid reservoir cavity 5, the controller cavity 8 and the high pressure cavity 306.
