Description

Technical Field

[0001] The utility model relates to the technical field of automobile thermal management systems, in particular to a coolant integrated module with motor bypass and an automobile thermal management system. Background Art

[0002] Automotive thermal management systems are widely used in various types of vehicles, including gasoline-powered and new energy vehicles. For gasoline-powered vehicles, thermal management systems primarily control engine cooling and the temperature of the air conditioning system. For new energy vehicles, particularly electric vehicles, thermal management systems are more complex, requiring simultaneous consideration of the temperature of the battery, motor, and passenger compartment.

[0003] With the development of automotive thermal management systems, people are increasingly pursuing higher levels of integration. However, current thermal management systems integrate relatively few loads, which undoubtedly reduces the integration level of the thermal management system. This results in a larger thermal management system footprint, a more crowded front cabin layout, and increased costs. Furthermore, current coolant integrated modules lack motor bypass flow paths, making it difficult to maintain the motor within the appropriate operating temperature range, thereby reducing motor efficiency, increasing energy consumption, and increasing costs.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0062] This embodiment provides a coolant integrated module with motor bypass, which has high integration, can save installation space, and achieve the purpose of cost saving; at the same time, it can improve the working efficiency of the motor unit, protect the motor unit, and save energy consumption.

[0063] like Figures 1-8 As shown, the coolant integrated module with motor bypass mainly includes a condenser 11, a motor unit 12, a radiator 13, a heater core 14, a battery cooler 15, a battery pack unit 16, a first water pump 31, a second water pump 32, a third water pump 33, a three-way proportional regulating valve 21, a first stop valve, a second stop valve, a third stop valve, a fourth stop valve, a fifth stop valve, a sixth stop valve, a seventh stop valve, an eighth stop valve, a ninth stop valve, a tenth stop valve, an eleventh stop valve, a twelfth stop valve, and a thirteenth stop valve; the three-way proportional regulating valve 21 has port a, port b and port c.

[0064] The coolant integrated module with motor bypass has idle battery cooling and motor self-circulation mode. In idle battery cooling and motor self-circulation mode:

[0065] The outlet of the condenser 11 is connected to port a and port c, port c is connected to the radiator 13 through the second stop valve, the radiator 13 is connected to the thirteenth stop valve, the third stop valve and the first water pump 31 in sequence, and the first water pump 31 is connected to the inlet of the condenser 11 to form a first high-temperature side closed loop.

[0066] The outlet of the battery cooler 15 is connected to the ninth shut-off valve and the third water pump 33 in sequence, the third water pump 33 is connected to the battery pack unit 16, the battery pack unit 16 is connected to the sixth shut-off valve, and the sixth shut-off valve is connected to the inlet of the battery cooler 15 to form a first low-temperature side closed loop.

[0067] The outlet of the motor unit 12 is connected to the second water pump 32 through the eleventh stop valve, and the second water pump 32 is connected to the inlet of the motor unit 12 to form a first motor coolant self-circulation loop.

[0068] Based on the above design, in this embodiment, through the first water pump 31, the second water pump 32, the third water pump 33 and the three-way proportional regulating valve 21, as well as the first stop valve, the second stop valve, the third stop valve, the fourth stop valve, the fifth stop valve, the sixth stop valve, the seventh stop valve, the eighth stop valve, the ninth stop valve, the tenth stop valve, the eleventh stop valve, the twelfth stop valve and the thirteenth stop valve, the condenser 11, the motor unit 12, the radiator 13, the warm core 14, the battery cooler 15 and the battery pack unit 16 loads are integrated into the coolant integrated module with motor bypass, thereby improving the integration of the coolant integrated module with motor bypass, saving installation space, improving space utilization and saving costs.

[0069] Furthermore, the coolant integrated module with motor bypass features idle battery cooling and motor self-circulation modes. This allows the battery pack unit 16 to be cooled when the vehicle is parked, extending its service life and improving safety. Simultaneously, the motor unit 12, connected in series with the second water pump 32 and the eleventh shut-off valve, can achieve self-circulation, maintaining a constant temperature and preventing localized overheating or underheating. This achieves a uniform temperature distribution across the motor unit 12, extending its service life, improving its efficiency, and conserving energy. Furthermore, in winter, the first motor coolant self-circulation loop can also store heat in the motor unit 12, saving energy.

[0070] It is understood that in the first motor coolant self-circulating loop, the second water pump 32 and the eleventh shut-off valve are configured to smoothly circulate the coolant, thereby achieving a circulating flow of the coolant in the first motor coolant self-circulating loop. Typically, the first motor coolant self-circulating loop circulates a medium-temperature coolant.

[0071] The three-way proportional control valve 21 in this embodiment can change parameters such as the flow rate, pressure, and temperature of the coolant according to the control signal, thereby achieving precise control of the coolant. The three-way proportional control valve 21 in this embodiment is a common component on the market, and its working principle and specific structure will not be described in detail here.

[0072] It can be understood that the coolant in the coolant integrated module with motor bypass in this embodiment exchanges heat with the refrigerant in the automobile thermal management system (the refrigerant circuit is not shown in the figure), thereby enabling the cooling of the coolant to be heated or cooled, thereby forming high-temperature side coolant and low-temperature side coolant under different working modes, so as to meet the heating or cooling requirements of the coolant for different loads under different working modes.

[0073] It can be understood that the warm core 14 in this embodiment is used to heat the vehicle cabin to meet the actual needs of passengers for the cabin temperature.

[0074] The first water pump 31, the second water pump 32 and the third water pump 33 in this embodiment are configured to drive the coolant to increase the flow rate of the coolant, thereby improving the working efficiency of the coolant integrated module with motor bypass.

[0075] In addition, the first water pump 31, the second water pump 32, the third water pump 33 and the three-way proportional regulating valve 21 in this embodiment, as well as the first stop valve, the second stop valve, the third stop valve, the fourth stop valve, the fifth stop valve, the sixth stop valve, the seventh stop valve, the eighth stop valve, the ninth stop valve, the tenth stop valve, the eleventh stop valve, the twelfth stop valve and the thirteenth stop valve are all arranged in the middle of the coolant integrated module with motor bypass, and the six loads are divided into two rows and respectively located on both sides of the coolant integrated module with motor bypass. This facilitates the flow path connection between each load, reduces the length of the flow path, and thus can reduce the heat loss of the coolant in the flow path, improve heat exchange efficiency, save energy consumption, and save costs. At the same time, such an arrangement can also improve the integration of the coolant integrated module with motor bypass, save installation space, have a simple structure, and occupy less space. In addition, it can also improve the convenience of flow path installation between each load, improve assembly efficiency, and is also conducive to later maintenance.

[0076] The first stop valve, the second stop valve, the third stop valve, the fourth stop valve, the fifth stop valve, the sixth stop valve, the seventh stop valve, the eighth stop valve, the ninth stop valve, the tenth stop valve, the eleventh stop valve, the twelfth stop valve and the thirteenth stop valve in this embodiment have the same structure and are all common components on the market. They have the functions of cutting off the coolant, regulating the flow rate, changing the flow direction of the coolant, preventing the coolant from flowing back and controlling the pressure in the flow path.

[0077] The motor-bypass integrated coolant module in this embodiment has multiple operating modes. For example, in addition to the idle battery cooling and motor self-circulation mode described above, it also features a battery waste heat cabin heating and motor self-circulation mode, a battery cooling mode, a cabin heating mode, a battery and cabin simultaneous heating mode, a battery heating mode, and a waste heat recovery mode. This can meet user needs for different modes, improve the user experience, and enhance the functional diversity and flexibility of the motor-bypass integrated coolant module.

[0078] The following describes the flow direction of the coolant in the coolant integrated module with motor bypass in different working modes. Figures 1-8 The abbreviations of the components are as follows:

[0079] Condenser 11 (WCC), motor unit 12 (EDU), radiator 13 (LTR), heater core 14 (HTR), battery cooler 15 (Chiller), battery pack unit 16 (BAT);

[0080] Three-way proportional control valve 21 (TWV);

[0081] a first water pump 31 (CP1), a second water pump 32 (CP2), and a third water pump 33 (CP3);

[0082] a first stop valve (SOV1), a second stop valve (SOV2), a third stop valve (SOV3), a fourth stop valve (SOV4), a fifth stop valve (SOV5), a sixth stop valve (SOV6), a seventh stop valve (SOV7), an eighth stop valve (SOV8), a ninth stop valve (SOV9), a tenth stop valve (SOV10), an eleventh stop valve (SOV11), a twelfth stop valve (SOV12), and a thirteenth stop valve (SOV13).

[0083] like Figure 2 As shown, when the coolant integrated module with motor bypass is in idle battery cooling and motor self-circulation mode, the coolant (high temperature) flowing out of the outlet of the condenser 11 passes through the a port and the c port of the three-way proportional regulating valve 21 in sequence and flows into the radiator 13, so that the coolant exchanges heat with the radiator 13. The coolant flowing out of the radiator 13 passes through the thirteenth stop valve and the third stop valve in sequence and is driven by the first water pump 31 to the inlet of the condenser 11, completing the circulation of the coolant in the first high-temperature side closed-loop circuit.

[0084] The coolant (low temperature) flowing out of the outlet of the battery cooler 15 passes through the ninth shut-off valve, the third water pump 33 and the battery pack unit 16 in sequence, so that the coolant can exchange heat with the battery pack unit 16. After heat exchange, the coolant passes through the sixth shut-off valve and the inlet of the battery cooler 15 in sequence and flows back into the battery cooler 15, completing the circulation of the coolant in the first low-temperature side closed-loop circuit.

[0085] The coolant (medium temperature) flowing out from the outlet of the motor unit 12 passes through the eleventh stop valve and the second water pump 32 in sequence and then flows back into the motor unit 12 to complete the circulation of the coolant in the self-circulation loop of the first motor coolant, thereby realizing the heat exchange effect between the medium-temperature coolant and the motor unit 12, so that the motor unit 12 can always be kept within a reasonable operating temperature, thereby improving the working efficiency of the motor unit 12.

[0086] It should be noted that in the idle battery cooling and motor self-circulation mode, idle battery cooling refers to cooling the battery pack unit 16 while the vehicle is parked, extending the service life of the battery pack unit 16 and improving safety. Simultaneously, the motor unit 12 can achieve self-circulation through the series connection of the second water pump 32 and the eleventh shut-off valve, allowing the motor unit 12 to maintain a constant temperature, avoiding localized overheating or underheating, extending the service life of the motor unit 12, improving its operating efficiency, and saving energy.

[0087] In this embodiment, the heat of the coolant in the first high-temperature side closed loop is exchanged with the refrigerant in the refrigerant circuit through the condenser 11, so that the coolant flowing out of the condenser 11 can be in a high-temperature state. The heat of the coolant in the first low-temperature side closed loop in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the battery cooler 15, so that the coolant flowing out of the battery cooler 15 can be in a low-temperature state. In this embodiment, the heat of the coolant in the first motor coolant self-circulation loop is exchanged with the motor unit 12, so that the motor unit 12 can always maintain a constant temperature state, avoiding the phenomenon of local excessive temperature or local excessive temperature, thereby achieving the effect of equalizing the temperature of the motor unit 12, extending the service life of the motor unit 12, improving the working efficiency of the motor unit 12, and saving energy. At the same time, in winter, the first motor coolant self-circulation loop can also store heat for the motor unit 12, saving energy.

[0088] like Figure 3As shown, when the coolant integrated module with motor bypass is in the battery waste heat heating cabin and motor self-circulation mode, the coolant (high temperature) flowing out of the outlet of the condenser 11 passes through the a port and the b port of the three-way proportional regulating valve 21 in sequence and then enters the heater core 14, heating the heater core 14 so that the heater core 14 releases heat to the cabin. The coolant that has undergone heat exchange is driven by the first water pump 31 to the inlet of the condenser 11, completing the circulation flow of the coolant in the second high-temperature side closed-loop circuit.

[0089] The coolant (low temperature) flowing out of the outlet of the battery cooler 15 passes through the ninth shut-off valve, the third water pump 33 and the battery pack unit 16 in sequence, so that the coolant can exchange heat with the battery pack unit 16. After heat exchange, the coolant passes through the sixth shut-off valve and the inlet of the battery cooler 15 in sequence and flows back into the battery cooler 15, completing the circulation of the coolant in the second low-temperature side closed-loop circuit.

[0090] The coolant (medium temperature) flowing out from the outlet of the motor unit 12 passes through the eleventh stop valve and the second water pump 32 in sequence and then flows back into the motor unit 12 to complete the coolant circulation flow in the second motor coolant self-circulation loop, thereby realizing the heat exchange effect between the medium-temperature coolant and the motor unit 12, so that the motor unit 12 can always be kept within a reasonable operating temperature, thereby improving work efficiency.

[0091] It should be noted that when the battery waste heat heats the cabin and the motor is in self-circulation mode, the heat of the battery pack unit 16 is cooled by the coolant, and the coolant transfers this heat to the battery cooler 15. Then the battery cooler 15 transfers this heat to the coolant in the condenser 11 through the refrigerant circuit (not shown in the figure), so that the coolant flowing out of the condenser 11 is a high-temperature coolant, which can then be used to heat the warm core 14 to achieve the heating effect on the cabin.

[0092] In this embodiment, the heat of the coolant in the second high-temperature side closed loop is exchanged with the refrigerant in the refrigerant circuit through the condenser 11, so that the coolant flowing out of the condenser 11 can be in a high-temperature state. The heat of the coolant in the second low-temperature side closed loop in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the battery cooler 15, so that the coolant flowing out of the battery cooler 15 can be in a low-temperature state. In this embodiment, the heat of the coolant in the second motor coolant self-circulation loop is exchanged with the motor unit 12, so that the motor unit 12 can always maintain a constant temperature state, avoiding the phenomenon of local excessive temperature or local excessive temperature, thereby achieving the effect of equalizing the temperature of the motor unit 12, extending the service life of the motor unit 12, improving the working efficiency of the motor unit 12, and saving energy. At the same time, in winter, the second motor coolant self-circulation loop can also store heat for the motor unit 12, saving energy.

[0093] like Figure 4 As shown, when the coolant integrated module with motor bypass is in battery cooling mode, in the battery cooling mode, the coolant (high temperature) flowing out from the outlet of the condenser 11 passes through the a port and c port of the three-way proportional regulating valve 21, the radiator 13, the twelfth stop valve, the second water pump 32 and the motor unit 12 in sequence, and the coolant exchanges heat with the motor unit 12. Then, the coolant after heat exchange passes through the third stop valve and the first water pump 31 in sequence and flows back to the inlet of the condenser 11, completing the circulation of the coolant in the third high-temperature side closed-loop circuit.

[0094] The coolant (low temperature) flowing out of the outlet of the battery cooler 15 passes through the ninth shut-off valve and the third water pump 33 in sequence and flows into the battery pack unit 16, so that the coolant exchanges heat with the battery pack unit 16. Then, the coolant after heat exchange flows back to the inlet of the battery cooler 15 through the sixth shut-off valve, completing the circulation of the coolant in the third low-temperature side closed-loop circuit.

[0095] The heat of the coolant in the third high-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the condenser 11, so that the coolant flowing out of the condenser 11 is kept at a high temperature. The heat of the coolant in the third low-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the battery cooler 15, so that the coolant flowing out of the battery cooler 15 is kept at a low temperature.

[0096] like Figure 5 As shown, when the coolant integrated module with motor bypass is in the cabin heating mode, the coolant (high temperature) flowing out of the outlet of the condenser 11 passes through the a port and the b port of the three-way proportional regulating valve 21 in sequence and enters the heater core 14, so that the coolant and the heater core 14 exchange heat. The heater core 14 heats the cabin, and the coolant flowing out of the heater core 14 flows back to the inlet of the condenser 11 through the first water pump 31 to complete the circulation of the coolant in the fourth high-temperature side closed-loop circuit.

[0097] The coolant (low temperature) flowing out of the outlet of the battery cooler 15 passes through the eighth stop valve, the radiator 13, the twelfth stop valve, and the second water pump 32 in sequence and then flows into the motor unit 12, so that the coolant and the motor unit 12 exchange heat and reduce the temperature of the motor unit 12. The coolant flowing out of the motor unit 12 passes through the fourth stop valve and then flows back to the inlet of the battery cooler 15 to complete the circulation of the coolant in the fourth low-temperature side closed-loop circuit.

[0098] The heat of the coolant in the fourth high-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the condenser 11, so that the coolant flowing out of the condenser 11 can be kept at a high temperature. The heat of the coolant in the fourth low-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the battery cooler 15, so that the coolant flowing out of the battery cooler 15 can be kept at a low temperature.

[0099] like Figure 6 As shown, in this embodiment, when the coolant integrated module with motor bypass is in simultaneous battery and cabin heating mode, the coolant (high temperature) flowing out of the outlet of the condenser 11 flows into port a of the three-way proportional control valve 21 and is divided into two parts. One portion flows through port b to the heater core 14, where it exchanges heat with the heater core 14. Finally, the coolant flowing out of the heater core 14 flows back to the inlet of the condenser 11 through the first water pump 31. The other portion flows through port c, the first shut-off valve, and the third water pump 33 to the battery pack unit 16, where it exchanges heat with the battery pack unit 16. The coolant flowing out of the battery pack unit 16 passes through the fifth shut-off valve, merges with the coolant flowing out of the heater core 14, and is then driven by the first water pump 31 to the inlet of the condenser 11, completing the coolant circulation in the fifth high-temperature side closed loop.

[0100] The coolant (low temperature) flowing out of the outlet of the battery cooler 15 passes through the eighth stop valve, the radiator 13, the twelfth stop valve, and the second water pump 32 in sequence and then flows into the motor unit 12, so that the coolant and the motor unit 12 exchange heat and reduce the temperature of the motor unit 12. The coolant flowing out of the motor unit 12 passes through the fourth stop valve and flows back to the inlet of the battery cooler 15 to complete the circulation flow of the coolant in the fifth low-temperature side closed-loop circuit.

[0101] The heat of the coolant in the fifth high-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the condenser 11, so that the coolant flowing out of the condenser 11 is kept at a high temperature. The heat of the coolant in the fifth low-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the battery cooler 15, so that the coolant flowing out of the battery cooler 15 is kept at a low temperature.

[0102] like Figure 7As shown, in this embodiment, when the coolant integrated module with motor bypass is in the battery heating mode, the coolant (high temperature) flowing out of the outlet of the condenser 11 passes through the a port and c port of the three-way proportional control valve 21, the first stop valve, and the third water pump 33 in sequence and flows into the battery pack unit 16, so that the coolant exchanges heat with the battery pack unit 16. The coolant flowing out of the battery pack unit 16 passes through the fifth stop valve and is driven by the first water pump 31 to the inlet of the condenser 11 to complete the circulation flow of the coolant in the sixth high-temperature side closed-loop circuit.

[0103] The coolant (low temperature) flowing out from the outlet of the battery cooler 15 passes through the eighth stop valve, the radiator 13, the twelfth stop valve, and the second water pump 32 in sequence and then flows into the motor unit 12, so that the coolant and the motor unit 12 exchange heat and reduce the temperature of the motor unit 12. The coolant flowing out of the motor unit 12 passes through the fourth stop valve and flows back to the inlet of the battery cooler 15 to complete the circulation flow of the coolant in the sixth low-temperature side closed-loop circuit.

[0104] The heat of the coolant in the sixth high-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the condenser 11, so that the coolant flowing out of the condenser 11 is kept at a high temperature. The heat of the coolant in the sixth low-temperature closed-loop circuit in this embodiment is exchanged with the refrigerant in the refrigerant circuit through the battery cooler 15, so that the coolant flowing out of the battery cooler 15 is kept at a low temperature.

[0105] Usually, the coolant on the low-temperature side can only exchange heat with the environment through the radiator 13. In this way, in the cold winter, the coolant does not absorb heat from the environment through the radiator 13 effectively, affecting the heat exchange effect. At the same time, the heat of the motor unit 12 is not well utilized, resulting in heat loss and increased costs.

[0106] Therefore, the coolant integrated module with motor bypass in this embodiment can effectively solve the technical problems of the coolant being unable to absorb heat to the environment through the radiator 13 when the ambient temperature is low, and the heat waste of the motor unit 12 through the waste heat recovery mode.

[0107] like Figure 8As shown, in this embodiment, when the coolant integrated module with motor bypass is in waste heat recovery mode, the coolant (high temperature) flowing out of the outlet of the condenser 11 flows into port a of the three-way proportional control valve 21 and is divided into two parts. One part of the coolant flows through port b to the heater core 14, where it exchanges heat with the heater core 14. Finally, the coolant flowing out of the heater core 14 flows back to the inlet of the condenser 11 through the first water pump 31. The other part of the coolant flows through port c, the first shut-off valve, and the third water pump 33 to the battery pack unit 16, where it exchanges heat with the battery pack unit 16. The coolant flowing out of the battery pack unit 16 passes through the fifth shut-off valve, merges with the coolant flowing out of the heater core 14, and is then driven by the first water pump 31 to the inlet of the condenser 11, completing the coolant circulation in the seventh high-temperature side closed loop.

[0108] The coolant (low temperature) flowing out of the outlet of the battery cooler 15 passes through the seventh stop valve and the second water pump 32 in sequence and flows into the motor unit 12, so that the coolant and the motor unit 12 exchange heat and reduce the temperature of the motor unit 12. The coolant flowing out of the motor unit 12 flows back to the inlet of the battery cooler 15 through the fourth stop valve to complete the circulation of the coolant in the seventh low-temperature side closed-loop circuit.

[0109] In this way, in the waste heat recovery mode, the coolant can absorb the heat of the motor unit 12, preventing the heat of the motor unit 12 from being lost, thereby achieving the function of waste heat recovery of the motor unit 12, saving energy consumption and cost.

[0110] The coolant in the seventh high-temperature closed-loop circuit in this embodiment exchanges heat with the refrigerant in the refrigerant circuit through the condenser 11, so that the coolant flowing out of the condenser 11 can be kept at a high temperature. The coolant in the seventh low-temperature closed-loop circuit in this embodiment exchanges heat with the refrigerant in the refrigerant circuit through the battery cooler 15, so that the coolant flowing out of the battery cooler 15 can be kept at a low temperature.

[0111] When the car is used in winter, although the motor unit 12 is heating up during driving, the motor unit 12 does not need to dissipate heat due to the low ambient temperature. The arrangement of the first motor coolant self-circulation loop and the second motor coolant self-circulation loop can, on the one hand, prevent the local temperature of the motor unit 12 from being too high, thereby achieving a uniform temperature for the motor unit 12; on the other hand, it can enable the heat generated by the motor unit 12 to be continuously accumulated. When the heat of the motor unit 12 exceeds a certain load, the coolant integrated module with motor bypass can switch to waste heat recovery mode, sending the heat to places that need heat, such as the cabin and battery pack unit 16. The motor unit 12 then self-circulates and stores heat, thereby improving the utilization rate of heat and achieving the purpose of saving energy and cost.

[0112] It should be noted that if Figure 2-Figure 8 As shown, in this embodiment, the first high-temperature side closed-loop circuit, the second high-temperature side closed-loop circuit, the third high-temperature side closed-loop circuit, the fourth high-temperature side closed-loop circuit, the fifth high-temperature side closed-loop circuit, the sixth high-temperature side closed-loop circuit and the seventh high-temperature side closed-loop circuit are all represented by dotted lines with arrows; the first low-temperature side closed-loop circuit, the second low-temperature side closed-loop circuit, the third low-temperature side closed-loop circuit, the fourth low-temperature side closed-loop circuit and the fifth low-temperature side closed-loop circuit, the sixth low-temperature side closed-loop circuit and the seventh low-temperature side closed-loop circuit are all represented by polylines with arrows; as shown Figure 2-Figure 3 As shown in FIG, the first motor coolant self-circulation loop and the second motor coolant self-circulation loop in this embodiment are both represented by double-dotted lines with arrows. It can be understood that, as Figure 2-Figure 8 The solid line in the figure indicates that there is no coolant flowing in the flow path in the corresponding working mode.

[0113] It is understandable that the coolant integrated module with motor bypass in this embodiment also includes a controller, which is electrically connected to the first water pump 31, the second water pump 32, the third water pump 33, the three-way proportional regulating valve 21; and the first stop valve, the second stop valve, the third stop valve, the fourth stop valve, the fifth stop valve, the sixth stop valve, the seventh stop valve, the eighth stop valve, the ninth stop valve, the tenth stop valve, the eleventh stop valve, the twelfth stop valve, and the thirteenth stop valve, so that the controller can control the flexible switching of the above seven working modes to meet the different needs of users. The controller in this embodiment is a component in the prior art, for example, it can be a conventional PLC controller. Therefore, the working principle and specific structure of the controller are not repeated in this embodiment.

[0114] This embodiment also provides an automobile thermal management system, which includes a refrigerant circuit and the above-mentioned coolant integrated module with motor bypass. The refrigerant circuit exchanges heat with the coolant integrated module with motor bypass through the condenser 11 and the battery cooler 15.

[0115] Because this automotive thermal management system utilizes the aforementioned coolant integrated module with motor bypass, it occupies less space in the vehicle's front cabin, improving overall vehicle space utilization, increasing the integration of the automotive thermal management system, and saving costs. Furthermore, the automotive thermal management system offers diverse operating modes to meet diverse user needs. Furthermore, the automotive thermal management system can extend the service life of the motor unit 12, improve its operating efficiency, and save energy.
