[0039] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0040] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower, top, and bottom", are usually defined by the upper, lower, top, and bottom of the thermal management system in normal use, and are only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation of the present disclosure. "Inside and outside" refer to the inside and outside of the corresponding component contours. In addition, the terms "first", "second", etc., are used to distinguish one element from another, and do not have order and importance.

[0041] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, and can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0042] like Figures 1 to 8As shown, according to the first aspect of the present disclosure, a thermal management system is provided, including a first heat exchanger 201, a second heat exchanger 202 and a compressor 101, wherein the exhaust port of the compressor 101 is suitable for being connected to the first opening 201-1 of the first heat exchanger 201, and the exhaust port of the compressor 101 is also suitable for being connected to the first opening 202-1 of the second heat exchanger 202, so that the heat exchange medium discharged through the exhaust port of the compressor 101 can exchange heat through the first heat exchanger 201 and the second heat exchanger 202.

[0043] Through the above technical solution, since the exhaust port of the compressor 101 can be connected to the first opening 201-1 of the first heat exchanger 201, and can also be connected to the first opening 202-1 of the second heat exchanger 202, the gaseous heat exchange medium discharged from the exhaust port of the compressor 101 can be heat exchanged through the first heat exchanger 201, and can also be heat exchanged through the second heat exchanger 202, which is beneficial to reduce the temperature of the heat exchange medium that exchanges heat with the battery, and further helps to improve the heat dissipation effect on the battery.

[0044] It can be understood that, in this article, "connected" and "connected" can refer to the connection between the two through a pipeline so that the heat exchange medium can flow between different components. For example, the exhaust port of the compressor 101 is connected to the first opening 201-1 of the first heat exchanger 201, which can mean that the exhaust port of the compressor 101 is connected to the first opening 201-1 of the first heat exchanger 201 through a pipeline, and the heat exchange medium can be transmitted between the two through the pipeline.

[0045] The present disclosure does not limit the positions of the first heat exchanger 201 and the second heat exchanger 202. As an implementation method, Figures 1 to 8 As shown, the first heat exchanger 201 may be an outdoor heat exchanger, and / or the second heat exchanger 202 may be an outdoor heat exchanger.

[0046] Alternatively, if Figures 1 to 8 As shown, the thermal management system may also include a first expansion valve 403 and a battery heat exchanger 401, the battery heat exchanger 401 is used to exchange heat with the battery, the first opening 401-1 of the battery heat exchanger 401 is suitable for being connected to the second opening 201-2 of the first heat exchanger 201 and the second opening 202-2 of the second heat exchanger 202 through the first expansion valve 403, and the second opening 401-2 of the battery heat exchanger 401 is suitable for being connected to the intake port 101-3 of the compressor 101.

[0047] The gaseous heat exchange medium discharged from the exhaust port of the compressor 101 can enter the air intake port 101-3 after passing through the first heat exchanger 201, the first expansion valve 403 and the battery heat exchanger 401 in sequence, and can also enter the air intake port 101-3 after passing through the second heat exchanger 202, the first expansion valve 403 and the battery heat exchanger 401 in sequence, that is, the gaseous heat exchange medium can exchange heat when passing through the first heat exchanger 201 and the second heat exchanger 202, such as exchanging heat with outdoor air to become a liquid heat exchange medium, and the liquid heat exchange medium can expand into a gas-liquid two-phase flow when passing through the first expansion valve 403, and the gas-liquid two-phase flow can exchange heat when passing through the battery heat exchanger 401, such as exchanging heat with the battery to become a gaseous heat exchange medium, and finally the gaseous heat exchange medium can enter the compressor 101 through the air intake port 101-3, forming a complete cycle and realizing heat dissipation of the battery.

[0048] Since the heat exchange medium can exchange heat with the outdoor air through the first heat exchanger 201 and can also exchange heat with the outdoor air through the second heat exchanger 202, the heat exchange medium can release heat multiple times before the first expansion valve 403, which is beneficial to reduce the temperature of the heat exchange medium flowing through the battery heat exchanger 401, and further beneficial to improve the heat dissipation effect on the battery.

[0049] It can be understood that the first opening and the second opening of the first heat exchanger 201, the second heat exchanger 202, the battery heat exchanger 401 and other devices in the present disclosure are interconnected. For example, the first opening 201-1 of the first heat exchanger 201 and the second opening 201-2 of the first heat exchanger 201 are interconnected, which will not be repeated herein.

[0050] The present disclosure does not limit the type of the battery heat exchanger 401. Optionally, the battery heat exchanger 401 can be a direct cooling and direct heating heat exchanger, such as a battery direct cooling plate. The heat exchange medium directly exchanges heat with the battery through the battery heat exchanger 401. On the one hand, it can reduce the setting of the intermediate heat exchanger and related components, which is conducive to saving space and improving the reliability of the thermal management system. On the other hand, it is conducive to reducing the heat exchange loss between the heat exchange medium and the battery, thereby facilitating the cooling effect on the battery.

[0051] Alternatively, if Figures 1 to 7 As shown, the exhaust port of the compressor 101 includes a first exhaust port 101-1 and a second exhaust port 101-2, the exhaust pressure of the first exhaust port 101-1 is lower than the exhaust pressure of the second exhaust port 101-2, the first exhaust port 101-1 is suitable for being connected to the first opening 201-1 of the first heat exchanger 201, and the second exhaust port 101-2 is suitable for being connected to the first opening 202-1 of the second heat exchanger 202.

[0052] Since the exhaust pressure of the first exhaust port 101-1 is lower than the exhaust pressure of the second exhaust port 101-2, the temperature of the heat exchange medium discharged from the first exhaust port 101-1 can be lower than the temperature of the heat exchange medium discharged from the second exhaust port 101-2. The heat exchange media at two temperatures can be respectively heat exchanged through the first heat exchanger 201 and the second heat exchanger 202, which is beneficial to increase the richness of the flow path of the thermal management system and facilitate the realization of thermal management in various modes.

[0053] Alternatively, if Figure 1 As shown, the thermal management system has a battery cooling mode. In the battery cooling mode, the first exhaust port 101-1 is connected to the first opening 201-1 of the first heat exchanger 201, the second exhaust port 101-2 is connected to the first opening 202-1 of the second heat exchanger 202, the second opening 201-2 of the first heat exchanger 201 and the second opening 202-2 of the second heat exchanger 202 are both connected to the first expansion valve 403, the first expansion valve 403 is connected to the first opening 401-1 of the battery heat exchanger 401, and the second opening 401-2 of the battery heat exchanger 401 is connected to the intake port 101-3 of the compressor 101.

[0054] Alternatively, if Figures 1 to 7 As shown, the thermal management system further includes a first fan 203, and the first fan 203 is configured to blow out wind that can sequentially pass through the first heat exchanger 201 and the second heat exchanger 202. Since the wind blown out by the first fan 203 can sequentially pass through the first heat exchanger 201 and the second heat exchanger 202, the outdoor air can first exchange heat with the first heat exchanger 201 and then exchange heat with the second heat exchanger 202.

[0055] When the first heat exchanger 201 and the second heat exchanger 202 are used as condensers (such as the first mode), the temperature of the heat exchange medium flowing through the first heat exchanger 201 is lower than the temperature of the heat exchange medium flowing through the second heat exchanger 202, and the outdoor air can exchange heat with the heat exchange medium in a step heat exchange mode (such as low-temperature air-medium-temperature heat exchange medium, medium-temperature air-high-temperature heat exchange medium), which is beneficial to narrowing the temperature difference between the outdoor air and the heat exchange medium and reducing irreversible losses, thereby helping to improve the overall energy efficiency of the system.

[0056] Similarly, when the first heat exchanger 201 and the second heat exchanger 202 are used as evaporators (such as the third mode), the temperature of the heat exchange medium flowing through the first heat exchanger 201 is greater than the temperature of the heat exchange medium flowing through the second heat exchanger 202, and the outdoor air can exchange heat with the heat exchange medium in a step heat exchange mode (such as high-temperature air-medium-temperature heat exchange medium, medium-temperature air-low-temperature heat exchange medium), which is beneficial to narrowing the temperature difference between the outdoor air and the heat exchange medium and reducing irreversible losses, thereby helping to improve the overall energy efficiency of the system.

The second opening 302-2 of the first indoor heat exchanger 302 is suitable for selectively connecting or disconnecting with the air intake port 101-3.

[0058] With such arrangement, the gaseous heat exchange medium discharged from the first exhaust port 101-1 can also enter the air intake port 101-3 after passing through the first heat exchanger 201, the second expansion valve 108, and the first indoor heat exchanger 302 in sequence, so that the indoor air can be cooled by absorbing heat through the first indoor heat exchanger 302.

[0059] Optionally, the thermal management system has an indoor cooling mode and an outdoor heat exchanger defrost mode, i.e., an in-vehicle cooling mode and an outdoor heat exchanger defrost mode.

[0060] Alternatively, if Figure 2 and Figure 7 As shown, the thermal management system also includes a third expansion valve 109 and a second indoor heat exchanger 301. The second heat exchanger 202 can be an outdoor heat exchanger.

The third expansion valve 109 is suitable for connecting with the first opening 301-1 of the second indoor heat exchanger 301. The second opening 301-2 of the second indoor heat exchanger 301 is suitable for selectively connecting or shutting off with the air intake port 101-3.

[0071] Similarly, when the second indoor heat exchanger 301 and the first indoor heat exchanger 302 are used as condensers (such as the third mode), the temperature of the heat exchange medium flowing through the second indoor heat exchanger 301 is lower than the temperature of the heat exchange medium flowing through the first indoor heat exchanger 302, and the indoor air can exchange heat with the heat exchange medium in a step heat exchange mode (such as low-temperature air-medium-temperature heat exchange medium, medium-temperature air-high-temperature heat exchange medium), which is beneficial to narrowing the temperature difference between the indoor air and the heat exchange medium and reducing irreversible losses, thereby helping to improve the overall energy efficiency of the system.

[0074] Alternatively, if Figure 3 and Figure 4 As shown, the thermal management system has an indoor heating mode, i.e., an in-vehicle heating mode. In the indoor heating mode, the first exhaust port 101-1 and the first opening 201-1 of the first heat exchanger 201 are cut off, the first exhaust port 101-1 and the second opening 301-2 of the second indoor heat exchanger 301 are connected, the first opening 301-1 of the second indoor heat exchanger 301 is connected to the third expansion valve 109, the third expansion valve 109 is connected to the second opening 202-2 of the second heat exchanger 202, and the first opening 202-1 of the second heat exchanger 202 is connected to the air intake port 101-3.

[0080] Alternatively, if Figure 4 As shown, the thermal management system also includes a multi-way valve A112, the first port 112-1 of the multi-way valve A112 is suitable for connecting to the second exhaust port 101-2, the second port 112-2 of the multi-way valve A112 is suitable for connecting to the second opening 302-2 of the first indoor heat exchanger 302, and the third port 112-3 of the multi-way valve A112 is suitable for connecting to the second opening 401-2 of the battery heat exchanger 401.

[0089] Such an arrangement is helpful in saving pipes of the thermal management system and in reducing the space occupied by the thermal management system.

[0090] The present disclosure does not limit the types of multi-way valve A112, multi-way valve H102, multi-way valve I103, multi-way valve J111, multi-way valve K105 and multi-way valve M405. As an embodiment, the multi-way valve A112, multi-way valve H102, multi-way valve I103, multi-way valve J111 and multi-way valve K105 can be three-way valves, and the multi-way valve M405 can be a four-way valve.

[0091] Alternatively, if Figure 5 As shown, the first exhaust port 101-1 is also suitable for selectively connecting or closing with the second opening 302-2 of the first indoor heat exchanger 302, and the first exhaust port 101-1 is also suitable for selectively connecting or closing with the first opening 201-1 of the first heat exchanger 201, the second exhaust port 101-2 is also suitable for selectively connecting or closing with the second opening 302-2 of the first indoor heat exchanger 302, and the second exhaust port 101-2 is also suitable for selectively connecting or closing with the first opening 202-1 of the second heat exchanger 202, and the second expansion valve 108 is also suitable for selectively connecting or closing with the first opening 301-1 of the second indoor heat exchanger 301.

[0092] The gaseous heat exchange medium discharged from the first exhaust port 101-1 and the second exhaust port 101-2 can flow through the first indoor heat exchanger 302, the second expansion valve 108 and the second indoor heat exchanger 301 in sequence and then enter the air intake port 101-3. When the gaseous heat exchange medium flows through the first indoor heat exchanger 302, it releases heat to the indoor air and becomes a liquid heat exchange medium. When the liquid heat exchange medium flows through the second expansion valve 108, it expands and becomes a gas-liquid two-phase flow. When the gas-liquid two-phase flow flows through the second indoor heat exchanger 301, it absorbs heat and becomes a gaseous state and enters the air intake port 101-3, completing the cycle and achieving dehumidification of the indoor air. Among them, the second indoor heat exchanger 301 is an evaporator responsible for air dehumidification, and the first indoor heat exchanger 302 is a condenser responsible for reheating the cooled indoor air and maintaining indoor thermal comfort. The indoor air with high relative humidity first flows through the second indoor heat exchanger 301 (evaporator), and the water vapor in the air quickly condenses on the low-temperature heat exchanger fins. At the same time, the air temperature decreases, and the condensed air enters the first indoor heat exchanger 302 (condenser), absorbs heat, and then rises in temperature, and is then transported back to the indoor passenger compartment. In this way, the indoor air is cooled down first and then heated up, effectively solving the problem of reduced indoor thermal comfort in the dehumidification mode of the traditional system.

[0093] Alternatively, if Figure 5 As shown, the thermal management system has an indoor dehumidification mode. In the indoor dehumidification mode, the first exhaust port 101-1 is cut off from the first opening 201-1 of the first heat exchanger 201, and the second exhaust port 101-2 is cut off from the first opening 202-1 of the second heat exchanger 202.

[0094] Here, the third port 405 - 3 of the multi-way valve M405 may be connected to the third port 104 - 3 of the multi-way valve L104 , so that the first exhaust port 101 - 1 may be communicated with the second opening 202 - 2 of the second heat exchanger 202 .

[0095] Alternatively, if Figure 5As shown, the thermal management system also includes a multi-way valve B106 and a multi-way valve C402. The first opening 302-1 of the first indoor heat exchanger 302 is connected to the first port 106-1 of the multi-way valve B106 through the second expansion valve 108, the second port 106-2 of the multi-way valve B106 is connected to the second opening 201-2 of the first heat exchanger 201, the third port 106-3 of the multi-way valve B106 is connected to the first port 402-1 of the multi-way valve C402, the second port 402-2 of the multi-way valve C402 is connected to the first opening 401-1 of the battery heat exchanger 401 through the first expansion valve 403, and the third port 402-3 of the multi-way valve C402 is connected to the first opening 301-1 of the second indoor heat exchanger 301. The multi-way valve C402 can realize that the first opening 301-1 of the second indoor heat exchanger 301 is connected to the first opening 401-1 of the battery heat exchanger 401 via the first expansion valve 403.

[0096] With such arrangement, the second opening 201-2 of the first heat exchanger 201 can be connected to the first opening 302-1 of the first indoor heat exchanger 302 via the second expansion valve 108, the second opening 201-2 of the first heat exchanger 201 can be connected to the first opening 401-1 of the battery heat exchanger 401 via the first expansion valve 403, the first opening 302-1 of the first indoor heat exchanger 302 can be connected to the first opening 401-1 of the battery heat exchanger 401 via the second expansion valve 108 and the first expansion valve 403 in sequence, and the first opening 302-1 of the first indoor heat exchanger 302 can be connected to the first opening 301-1 of the second indoor heat exchanger 301 via the second expansion valve 108, and this is beneficial to saving piping of the thermal management system and reducing the space occupied by the thermal management system.

[0097] The present disclosure does not limit the types of the multi-way valve B106 and the multi-way valve C402. As an implementation mode, the multi-way valve C402 may be a three-way valve, and the multi-way valve B106 may be a four-way valve.

[0099] By connecting the first exhaust port 101 - 1 to the air intake port 101 - 3 , the heat exchange medium discharged from the first exhaust port 101 - 1 can be directly replenished back into the compressor 101 .

[0100] The second exhaust port 101-2 is connected to the second opening 302-2 of the first indoor heat exchanger 302, and the second expansion valve 108 is connected to the first opening 301-1 of the second indoor heat exchanger 301 and the first opening 401-1 of the battery heat exchanger 401, so that the heat exchange medium discharged from the second exhaust port 101-2 can enter the air intake port 101-3 after passing through the first indoor heat exchanger 302, the second expansion valve 108 and the second indoor heat exchanger 301 in sequence, or enter the air intake port 101-3 after passing through the first indoor heat exchanger 302, the second expansion valve 108 and the battery heat exchanger 401 in sequence, thereby achieving dehumidification of the indoor air and cooling of the battery at the same time.

In the indoor dehumidification + battery cooling mode, the first exhaust port 101-1 and the first opening 201-1 of the first heat exchanger 201 are cut off, and the first exhaust port 101-1 and the air intake port 101-3 are connected. The second exhaust port 101-2 is blocked from the first opening 202-1 of the second heat exchanger 202, the second exhaust port 101-2 is connected to the second opening 302-2 of the first indoor heat exchanger 302, the first opening 302-1 of the first indoor heat exchanger 302 is connected to the second expansion valve 108, the second expansion valve 108 is connected to the first opening 301-1 of the second indoor heat exchanger 301, the second opening 301-2 of the second indoor heat exchanger 301 is connected to the air intake port 101-3, The second expansion valve 108 is also in communication with the first expansion valve 403 . The first expansion valve 403 is in communication with the first opening 401 - 1 of the battery heat exchanger 401 . The first opening 401 - 2 of the battery heat exchanger 401 is in communication with the air intake port 101 - 3 .

[0102] Here, the third port 405 - 3 of the multi-way valve M405 may be connected to the third port 104 - 3 of the multi-way valve L104 , so that the first exhaust port 101 - 1 may communicate with the intake port 101 - 3 .

[0103] Alternatively, if Figures 1 to 8 As shown, the thermal management system further includes a gas-liquid separator 114. Arranging the gas-liquid separator 114 upstream of the air intake port 101-3 is helpful to prevent the compressor 101 from being damaged by liquid inhalation and causing liquid in the compressor 101.

[0104] Alternatively, if Figures 1 to 8As shown, the compressor 101 is a single-suction double-row compressor 101, and the gas-liquid separator 114 is arranged upstream of the suction port 101-3 of the single-suction double-row compressor 101. The single-suction double-row compressor 101 can be provided with only one gas-liquid separator 114, which is conducive to simplifying the structure of the thermal management system and reducing the space occupied by the thermal management system.

[0105] It can be understood that the upstream and downstream here refer to the upstream and downstream of the flow of the heat exchange medium, that is, the heat exchange medium flows from the gas-liquid separator 114 to the air intake port 101 - 3 .

[0106] Alternatively, if Figure 4 As shown, the thermal management system also includes a motor electronic control unit 500 and a third heat exchanger 508 , wherein the heat exchange medium flowing out of the first opening 302 - 1 of the first indoor heat exchanger 302 and passing through the second expansion valve 108 is suitable for heat exchange with the motor electronic control unit 500 through the third heat exchanger 508 .

[0107] By such arrangement, the heat exchange medium discharged from the second exhaust port 101-2 can enter the air intake port 101-3 after passing through the first indoor heat exchanger 302, the second expansion valve 108 and the third heat exchanger 508 in sequence, so that the heat exchange medium and the motor electronic control unit 500 can be heat exchanged through the third heat exchanger 508, thereby realizing cooling of the motor electronic control unit 500 or waste heat recovery.

[0108] The present disclosure does not limit the type of the third heat exchanger 508. As an implementation manner, the third heat exchanger 508 may be a plate heat exchanger.

[0109] Here, optionally, the multi-way valve B106 and the multi-way valve L104 can be four-way valves, the fourth port 106-4 of the multi-way valve B106 is connected to the first opening 508-1 of the third heat exchanger 508, and the fourth port 104-4 of the multi-way valve L104 is connected to the second opening 508-2 of the third heat exchanger 508, so that the heat exchange medium flowing out from the first opening 302-1 of the first indoor heat exchanger 302 and passing through the second expansion valve 108 can flow through the fourth heat exchanger 505.

[0110] Alternatively, if Figures 1 to 8As shown, the motor electronic control unit 500 also includes a water pump 501, a motor electronic control module 500-1 and a fourth heat exchanger 505. The motor electronic control unit 500 includes a first coolant flow path 511, a second coolant flow path 512 and a third coolant flow path 513. The first end of the first coolant flow path 511 is selectively connected to the first end of the second coolant flow path 512 or the first end of the third coolant flow path 513, and the second end of the first coolant flow path 511 is selectively connected to the second end of the second coolant flow path 512 or the second end of the third coolant flow path 513. The water pump 501 and the motor electronic control module 500-1 are connected in series on the first coolant flow path 511, the fourth heat exchanger 505 is arranged on the second coolant flow path 512, and the third heat exchanger 508 is arranged on the third coolant flow path 513.

[0111] The first end of the first coolant flow path 511 can be connected to the first end of the second coolant flow path 512, and the second end of the first coolant flow path 511 can be connected to the second end of the second coolant flow path 512, so that the first coolant flow path 511 and the second coolant flow path 512 form a loop, and the coolant flowing through the first coolant flow path 511 is cooled by the fourth heat exchanger 505 to achieve cooling of the motor electronic control module 500-1.

[0112] The first end of the first coolant flow path 511 can also be connected to the first end of the third coolant flow path 513, and the second end of the first coolant flow path 511 can be connected to the second end of the third coolant flow path 513, so that the first coolant flow path 511 and the third coolant flow path 513 form a loop. Since the second heat exchange medium and the coolant flowing through the first coolant flow path 511 can exchange heat in the third heat exchanger 508, the motor electronic control module 500-1 can be cooled or the waste heat of the motor electronic control module 500-1 can be recovered.

[0113] Here, the motor electronic control module 500 - 1 includes but is not limited to electronic control and motor. For example, the coolant flowing through the first coolant flow path 511 can exchange heat with the electronic control through the electronic control cooling plate 502 , and can also exchange heat with the motor through the motor water jacket 503 .

[0114] In order to realize the above-mentioned connection relationship among the first cooling liquid flow path 511, the second cooling liquid flow path 512 and the third cooling liquid flow path 513, as an implementation mode, as shown in FIG. Figures 1 to 7As shown, the motor electronic control unit 500 may include a multi-way valve N504 and a multi-way valve O507, the first port 504-1 of the multi-way valve N504 may be connected to the first end of the first coolant flow path 511, the second port 504-2 of the multi-way valve N504 may be connected to the first end of the second coolant flow path 512, the third port 504-3 of the multi-way valve N504 may be connected to the first end of the third coolant flow path 513, the first port 507-1 of the multi-way valve O507 may be connected to the second end of the first coolant flow path 511, the second port 507-2 of the multi-way valve O507 may be connected to the second end of the second coolant flow path 512, and the third port 507-3 of the multi-way valve O507 may be connected to the second end of the third coolant flow path 513.

[0115] The present disclosure does not limit the types of the multi-way valve N504 and the multi-way valve O507. Optionally, the multi-way valve N504 and the multi-way valve O507 may be three-way valves.

[0116] The present disclosure does not limit the type of the fourth heat exchanger 505. As an implementation method, Figures 1 to 7 As shown, the fourth heat exchanger 505 can be an air-cooled heat exchanger, and the thermal management system also includes a third fan 506, which is used to blow air to the fourth heat exchanger 505. The third fan 506 can blow air to the fourth heat exchanger 505 to take away the heat of the coolant flowing through the fourth heat exchanger 505.

[0117] Alternatively, if Figure 8 As shown, the first fan 203 is configured to blow out wind that can sequentially pass through the first heat exchanger 201, the second heat exchanger 202, and the fourth heat exchanger 505. In this configuration, the wind blown out by the first fan 203 can be used to dissipate heat from the fourth heat exchanger 505, so that there is no need to additionally set up the third fan 506, which is beneficial to simplifying the structure of the thermal management system and reducing the energy consumption of the thermal management system.

[0118] Furthermore, in the flow direction of the wind blown out by the first fan 203 , the fourth heat exchanger 505 is disposed downstream of the second heat exchanger 202 , which is also beneficial to avoid affecting the cascade heat exchange between the outdoor air and the first heat exchanger 201 and the second heat exchanger 202 .

[0119] The thermal management system provided by the present disclosure can be applied to suitable fields, and the present disclosure does not limit this. For example, according to the second aspect of the present disclosure, a terminal device is provided, including the thermal management system according to the above.

[0120] Optionally, the terminal device may be a vehicle, that is, the thermal management system may be a vehicle thermal management system.

[0121] It can be understood that the thermal management system of the present disclosure can be used not only on vehicles, but also on any other equipment suitable for adopting the thermal management system, and the present disclosure is not limited to this.

[0122] For ease of understanding, the following will take the vehicle thermal management system as an example and combine Figures 1 to 7 To describe the cycle process and principle of the main working mode of the thermal management system provided by the present invention.

[0123] Mode 1: Battery cooling + motor and electronic control cooling. Figure 1 As shown, in this mode, the process of the heat exchange medium is as follows: the medium-pressure and medium-temperature gaseous heat exchange medium is discharged from the first exhaust port 101-1, enters the first heat exchanger 201 through the multi-way valve H102 and the multi-way valve L104, exchanges heat with the air in the first heat exchanger 201, releases heat to become a low-temperature liquid heat exchange medium, and then enters the multi-way valve C402 through the multi-way valve B106; the high-pressure and high-temperature gaseous heat exchange medium is discharged from the second exhaust port 101-2, enters the second heat exchanger 202 through the multi-way valve I103 and the multi-way valve K105, exchanges heat with the air in the second heat exchanger 202, releases heat to become a medium-temperature liquid heat exchange medium, and then enters the multi-way valve C402 through the multi-way valve D107 and the multi-way valve E110. The above two heat exchange media enter the first expansion valve 403 together through the multi-way valve C402, expand into a low-temperature gas-liquid two-phase flow and enter the battery heat exchanger 401 to cool the battery pack. The heat exchange medium itself absorbs heat and becomes a low-temperature gas, enters the gas-liquid separator 114 through the multi-way valve F404, the multi-way valve M405, and the multi-way valve G113, and finally returns to the compressor 101, forming a complete cycle.

[0124] The flow of the coolant is as follows: under the action of the water pump 501, the coolant flows through the electronically controlled cooling plate 502 and the motor water jacket 503 in sequence to absorb heat, then flows into the fourth heat exchanger 505 through the multi-way valve N504 to release heat to the air, and finally returns to the inlet of the water pump 501 through the multi-way valve O507, forming a complete cycle.

[0125] The flow of the air outside the vehicle is as follows: the low-temperature air outside the vehicle first flows through the first heat exchanger 201 to absorb heat and is heated to a medium temperature, and then flows through the second heat exchanger 202 to absorb heat and is heated to a high temperature. Therefore, the air and the heat exchange medium in the heat exchange module outside the vehicle exchange heat in a step-by-step heat exchange mode (low-temperature air-medium-temperature heat exchange medium, medium-temperature air-high-temperature heat exchange medium), which reduces irreversible losses and is conducive to improving system energy efficiency.

[0126] Mode 2: In-car cooling + battery cooling + motor and electronic control cooling. Figure 2As shown, in this mode, the process of the heat exchange medium is as follows: the medium-pressure and medium-temperature gaseous heat exchange medium is discharged from the first exhaust port 101-1, enters the first heat exchanger 201 through the multi-way valve H102 and the multi-way valve L104, exchanges heat with the air in the first heat exchanger 201, releases heat and becomes a low-temperature liquid heat exchange medium, is diverted through the multi-way valve B106, the first diverted flow enters the second expansion valve 108, expands into a low-temperature gas-liquid two-phase flow in the second expansion valve 108, enters the first indoor heat exchanger 302, absorbs heat in the first indoor heat exchanger 302 and becomes a gas, enters the multi-way valve F404 through the multi-way valve A112, and the second diverted heat exchange medium enters the first expansion valve 403 through the multi-way valve C402, and expands into a low-temperature gas-liquid two-phase flow in the first expansion valve 403. The low-temperature gas-liquid two-phase flow enters the battery heat exchanger 401, absorbs heat and becomes gas, and enters the multi-way valve F404. The above two heat exchange media merge at the multi-way valve F404, and enter the multi-way valve G113 through the multi-way valve M405. The high-pressure and high-temperature gaseous heat exchange medium is discharged from the second exhaust port 101-2, and enters the second heat exchanger 202 through the multi-way valve I103 and the multi-way valve K105. In the second heat exchanger 202, it exchanges heat with the air, releases heat and becomes a medium-temperature liquid heat exchange medium, and then enters the third expansion valve 109 through the multi-way valve D107. In the third expansion valve 109, it expands and becomes a medium-temperature gas-liquid two-phase flow and enters the second indoor heat exchanger 301. In the second indoor heat exchanger 301, it absorbs heat and becomes gas, and enters the multi-way valve G113 through the multi-way valve J111. The above three heat exchange media all enter the gas-liquid separator 114 through the multi-way valve G113, and finally return to the suction port 101-3 of the compressor 101, forming a complete cycle.

[0127] The flow of coolant and outside air is the same as in mode 1.

[0128] The process of the air in the car is as follows: the high-temperature air in the car first flows through the second indoor heat exchanger 301 to release heat and is cooled to medium temperature, and then flows through the first indoor heat exchanger 302 to release heat and is cooled to low temperature. Therefore, the air and the heat exchange medium in the heat exchange module in the car exchange heat in a step-by-step heat exchange mode (high-temperature air-medium-temperature heat exchange medium, medium-temperature air-low-temperature heat exchange medium), which reduces irreversible losses and is conducive to improving system energy efficiency.

[0129] Mode 3: In-car heating + battery waste heat recovery + motor and electronic control waste heat recovery. Figure 3As shown, in this mode, the flow of the heat exchange medium is as follows: the medium-temperature medium-pressure gaseous heat exchange medium is discharged from the first exhaust port 101-1, enters the second indoor heat exchanger 301 through the multi-way valve H102 and the multi-way valve J111, releases heat in the second indoor heat exchanger 301 to become a low-temperature liquid heat exchange medium, and enters the multi-way valve E110. The heat exchange medium is divided into two paths in the multi-way valve E110. The first path passes through the third expansion valve 109, expands into a low-temperature gas-liquid two-phase flow, enters the second heat exchanger 202 through the multi-way valve D107, absorbs heat in the second heat exchanger 202 to become a gaseous state, enters the multi-way valve M405 through the multi-way valve K105, and the second path passes through the multi-way valve C402 to enter the first expansion valve 403, expands into a low-temperature gas-liquid two-phase flow in the first expansion valve 403 to enter the battery heat exchanger 401, absorbs heat in the battery heat exchanger 401 to become a gaseous state, and enters the multi-way valve M405 through the multi-way valve F404. The high-temperature and high-pressure gaseous heat exchange medium is discharged from the second exhaust port 101-2, enters the first indoor heat exchanger 302 through the multi-way valve I103 and the multi-way valve A112, releases heat in the first indoor heat exchanger 302 to become a medium-temperature liquid heat exchange medium, expands into a low-temperature gas-liquid two-phase flow through the second expansion valve 108, and is divided into two paths in the multi-way valve B106. The first path enters the first heat exchanger 201 to absorb heat and become a gaseous state, and the second path enters the third heat exchanger 508 to absorb heat and become a gaseous state. The two paths of heat exchange medium merge in the multi-way valve L104 and flow into the multi-way valve M405. The three paths of heat exchange medium flowing into the multi-way valve M405 flow into the multi-way valve G113 and the gas-liquid separator 114 together, and finally return to the suction port 101-3 of the compressor 101, forming a complete cycle.

[0130] The process of the air in the car is as follows: the low-temperature air in the car first flows through the second indoor heat exchanger 301 to absorb heat and is heated to a medium temperature, and then flows through the first indoor heat exchanger 302 to absorb heat and is heated to a high temperature. Therefore, the air and the heat exchange medium in the heat exchange module in the car exchange heat in a step-by-step heat exchange mode (low-temperature air-medium-temperature heat exchange medium, medium-temperature air-high-temperature heat exchange medium), which reduces irreversible losses and is conducive to improving system energy efficiency.

[0131] The flow of the air outside the vehicle is as follows: the high-temperature air outside the vehicle first flows through the first heat exchanger 201 to release heat and is cooled to a medium temperature, and then flows through the second heat exchanger 202 to release heat and is cooled to a low temperature. Therefore, the air and the heat exchange medium in the heat exchange module outside the vehicle exchange heat in a step-by-step heat exchange mode (high-temperature air-medium-temperature heat exchange medium, medium-temperature air-low-temperature heat exchange medium), which reduces irreversible losses and is conducive to improving system energy efficiency.

[0132] The flow of the coolant is as follows: under the action of the water pump 501, the coolant flows through the electronically controlled cooling plate 502 and the motor water jacket 503 in sequence to absorb heat, then flows into the third heat exchanger 508 through the multi-way valve N504 to release heat, and finally returns to the inlet of the water pump 501 through the multi-way valve O507, forming a complete cycle.

[0133] In the above process, the air conditioning system recovers waste heat from the battery and motor electronic control, effectively improving the heating capacity of the air conditioning system. On the other hand, the relatively high temperature heat exchange medium is divided into the plate heat exchanger, and the relatively low temperature heat exchange medium is divided into the battery cold plate, which reduces the irreversible loss of the heat exchange process in the plate heat exchanger and the cold plate, and is also conducive to improving the overall energy efficiency of the system.

[0134] Mode 4: Car heating + battery preheating. Figure 4 As shown, in this mode, the process of the heat exchange medium is as follows: the medium-temperature and medium-pressure gaseous heat exchange medium is discharged from the first exhaust port 101-1, enters the second indoor heat exchanger 301 through the multi-way valve H102 and the multi-way valve J111, releases heat in the second indoor heat exchanger 301 to become a low-temperature liquid heat exchange medium, and then enters the third expansion valve 109 through the multi-way valve E110, expands to become a low-temperature gas-liquid two-phase flow, enters the second heat exchanger 202 through the multi-way valve D107 to absorb heat and become a gas, enters the multi-way valve M405 through the multi-way valve K105, and the high-temperature and high-pressure gaseous heat exchange medium is discharged from the second exhaust port 101-2, enters the multi-way valve A112 through the multi-way valve I103, and is divided into two paths in the multi-way valve A112. The first path enters the first indoor heat exchanger 302, and the second path enters the second indoor heat exchanger 302. It releases heat in the first indoor heat exchanger 302 to become a medium-temperature liquid heat exchange medium, expands into a low-temperature gas-liquid two-phase flow through the second expansion valve 108 and enters the multi-way valve B106. The second path enters the battery heat exchanger 401 through the multi-way valve F404, releases heat in the battery heat exchanger 401 to become a medium-temperature liquid heat exchange medium, and then expands into a low-temperature gas-liquid two-phase flow through the first expansion valve 403. The heat exchange medium entering the multi-way valve B106 through the multi-way valve C402 merges and then enters the first heat exchanger 201 to absorb heat and become a gaseous heat exchange medium, and enters the multi-way valve M405 through the multi-way valve L104. The heat exchange medium entering the multi-way valve M405 in two ways merges and then returns to the suction port 101-3 of the compressor 101 through the multi-way valve G113 and the gas-liquid separator 114, forming a complete cycle.

[0135] The air flow inside and outside the vehicle is the same as mode 3.

[0136] In this mode, the motor electronic control cooling / waste heat recovery module does not start.

[0137] Mode 5: Dehumidification in the car. Figure 5As shown in the figure, in this mode, the process of the heat exchange medium is as follows: the medium-temperature and medium-pressure gaseous heat exchange medium is discharged from the first exhaust port 101-1, and enters the multi-way valve A112 through the multi-way valve H102, the multi-way valve L104, the multi-way valve M405, and the multi-way valve F404; the high-temperature and high-pressure gaseous heat exchange medium is discharged from the second exhaust port 101-2, and enters the multi-way valve A112 through the multi-way valve I103; the above two heat exchange media are combined at the multi-way valve A112 and enter the second exhaust port 101-2. In the first indoor heat exchanger 302, heat is released to become a medium-temperature liquid heat exchange medium, which is expanded by the second expansion valve 108 to become a low-temperature gas-liquid two-phase flow, and enters the second indoor heat exchanger 301 through the multi-way valve B106, the multi-way valve C402, and the multi-way valve E110, and absorbs heat in the second indoor heat exchanger 301 to become a gas, and returns to the air intake 101-3 of the compressor 101 through the multi-way valve J111, the multi-way valve G113, and the gas-liquid separator 114 to complete the cycle. In this mode, the second indoor heat exchanger 301 is an evaporator responsible for air dehumidification, and the first indoor heat exchanger 302 is a condenser responsible for reheating the cooled air in the car and maintaining the thermal comfort in the car.

[0138] The process of air in the car is as follows: the air with high relative humidity in the car first flows through the second indoor heat exchanger 301 (evaporator), and the water vapor in the air quickly condenses on the low-temperature heat exchanger fins, while the air temperature decreases. The condensed air enters the first indoor heat exchanger 302 (condenser), absorbs heat, and then rises in temperature, and is then transported back to the passenger compartment. In this mode, the air is cooled first and then heated, which effectively solves the problem of reduced thermal comfort in the car under the dehumidification mode of the traditional system.

[0139] Mode 6: Dehumidification in the car + battery cooling. Figure 6 As shown, in this mode, the process of the heat exchange medium is as follows: the high-temperature and high-pressure gaseous heat exchange medium is discharged from the second exhaust port 101-2, enters the first indoor heat exchanger 302 through the multi-way valve I103 and the multi-way valve A112, releases heat to become a medium-temperature liquid heat exchange medium, expands through the second expansion valve 108 to become a low-temperature gas-liquid two-phase flow, enters the multi-way valve C402 through the multi-way valve B106, and the heat exchange medium is divided into two paths in the multi-way valve C402. One path enters the second indoor heat exchanger 301 through the multi-way valve E110, absorbs heat in the second indoor heat exchanger 301 and becomes a gaseous state, and passes through the multi-way valve J111 and the multi-way valve G112. 113, the gas-liquid separator 114 returns to the suction port 101-3 of the compressor 101, and the other path is expanded twice through the first expansion valve 403, enters the battery heat exchanger 401 to absorb heat and become gas, and enters the multi-way valve M405 through the multi-way valve F404. The medium-temperature and medium-pressure gaseous heat exchange medium discharged from the first exhaust port 101-1 does not participate in the heat exchange, and enters the multi-way valve M405 through the multi-way valve H102 and the multi-way valve L104. After the two paths of gaseous heat exchange media merge at the multi-way valve M405, they return to the suction port 101-3 of the compressor 101 through the multi-way valve G113 and the gas-liquid separator 114 to complete the cycle.

[0140] The air flow inside the car is the same as mode 5.

[0141] Mode 7: Defrosting of the external heat exchanger. Figure 7 As shown, in this mode, the process of the heat exchange medium is as follows: the medium-pressure and medium-temperature gaseous heat exchange medium is discharged from the first exhaust port 101-1, enters the first heat exchanger 201 through the multi-way valve H102 and the multi-way valve L104, exchanges heat with the air in the first heat exchanger 201, releases heat to become a low-temperature liquid heat exchange medium, enters the second expansion valve 108 through the multi-way valve B106, expands into a low-temperature gas-liquid two-phase flow in the second expansion valve 108, enters the first indoor heat exchanger 302, absorbs heat in the first indoor heat exchanger 302 to become a gaseous state, passes through the multi-way valve A112, the multi-way valve F404, The multi-way valve M405 enters the multi-way valve G113, and the high-pressure and high-temperature gaseous heat exchange medium is discharged from the second exhaust port 101-2, and enters the second heat exchanger 202 through the multi-way valve I103 and the multi-way valve K105, and exchanges heat with the air in the second heat exchanger 202, releases heat and becomes a medium-temperature liquid heat exchange medium, and then enters the third expansion valve 109 through the multi-way valve D107, expands in the third expansion valve 109 to become a medium-temperature gas-liquid two-phase flow and enters the second indoor heat exchanger 301, absorbs heat in the second indoor heat exchanger 301 to become a gas, and enters the multi-way valve G113 through the multi-way valve J111. The above two heat exchange media both enter the gas-liquid separator 114 through the multi-way valve G113, and finally return to the air intake port 101-3 of the compressor 101, forming a complete cycle. In this mode, the two heat exchangers outside the vehicle act as condensers, into which medium and high temperature heat exchange media flow. The frost on the heat exchangers is heated and turns into liquid and flows out along the fins, thereby achieving the purpose of defrosting.
