Description

Thermal Management System Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a vehicle thermal management system. Background Technology

[0002] For hybrid and electric vehicles, there are multiple thermal management requirements. For example, the traction motor needs cooling, the battery needs cooling or heating under different operating conditions, and the passenger compartment needs cooling or heating in different seasons. Therefore, the thermal management system of an electric vehicle includes multiple loops, such as the motor loop, the battery loop, and the passenger compartment temperature control loop. Moreover, under different operating conditions, the heat exchange medium has different flow direction requirements in each loop.

[0003] During cooling, the passenger compartment typically operates by a compressor drawing gaseous refrigerant from the evaporator, compressing it into a high-pressure gas, and then releasing heat through a heat exchanger to liquefy it. The liquid refrigerant then passes through an expansion valve into the evaporator, absorbs a large amount of heat, evaporates back into a gas, and is then drawn away by the compressor, creating a cycle. The cooled air is then blown into the passenger compartment by a blower, achieving a cooling effect. However, this cooling system involves heat exchange within the passenger compartment, posing a risk of refrigerant leakage, especially for flammable refrigerants, which could lead to significant safety hazards. Summary of the Invention

[0069] First Embodiment

[0070] Referring to Figure 1, the thermal management system provided in the first embodiment of the present invention includes a first valve 11, a second valve 13, a heating heat exchanger 15, a first cooling heat exchanger 17, a second cooling heat exchanger 19, a heater core 21, and a cooler core 23. The heating heat exchanger 15 facilitates heat exchange between a high-temperature refrigerant and a coolant, resulting in a high-temperature coolant. The first cooling heat exchanger 17 and the second cooling heat exchanger 19 facilitate heat exchange between a low-temperature refrigerant and a coolant, resulting in a low-temperature coolant. The heater core 21 and the cooler core 23 are typically located within the passenger compartment of the vehicle, thereby heating or cooling the passenger compartment through the high-temperature coolant in the heater core 21 or the low-temperature coolant in the cooler core 23.

[0071] Both the heating heat exchanger 15 and the heater core 21 are connected to the first valve 11. High-temperature coolant flowing from the heating heat exchanger 15 flows into the heater core 21 through the first valve 11. The first refrigeration heat exchanger 17 and / or the second refrigeration heat exchanger 19, as well as the cooler core 23, are all connected to the second valve 13. Low-temperature coolant flowing from the first evaporator 17 and / or the second refrigeration heat exchanger 19 flows into the cooler core 23 through the second valve 13. It is understood that the second refrigeration heat exchanger 19 can be omitted, and heat exchange between the first refrigeration heat exchanger 17 and the cooler core 23 is only performed through the first refrigeration heat exchanger 17.

[0072] In the thermal management system of this embodiment, since the cooler core and heater core that cool or heat the passenger compartment exchange heat with the air in the passenger compartment through coolant, there is no need to introduce refrigerant into the passenger compartment. Therefore, the problem of refrigerant leakage in the passenger compartment is avoided, which can greatly improve the safety of the vehicle, especially for flammable refrigerants. At the same time, the circulation of high-temperature coolant between heater core 21 and heating heat exchanger 15 can be realized through the first valve 11, and the circulation of low-temperature refrigerant between cooler core 23 and first cooling heat exchanger and / or second cooling heat exchanger 19 can be realized through the second valve 13. This avoids unnecessary heat exchange between high and low temperature coolants in the valves, thereby improving the cooling and heating effect.

[0073] In the embodiment shown in Figure 1, a first valve 11 is connected to a heating heat exchanger 15 to form a first loop; a first valve 11 is connected to a heater core 21 to form a second loop; a second valve 13 is connected to a first cooling heat exchanger 17 to form a third loop; a second valve 13 is connected to a second cooling heat exchanger 19 to form a fourth loop; and a second valve 13 is connected to a cooler core 23 to form a fifth loop. The first valve 11 is configured to connect or disconnect the first and second loops, and the second valve 13 is configured to connect or disconnect the third and / or fourth and fifth loops. The first, second, third, fourth, and fifth loops are used to supply coolant (e.g., cooling water). The heating heat exchanger 15 is used to supply high-temperature coolant to the heater core 21 when the first loop is connected to the second loop; the first cooling heat exchanger 17 is used to supply low-temperature coolant to the cooler core 23 when the third loop is connected to the fifth loop; and the second cooling heat exchanger 19 is used to supply low-temperature coolant to the cooler core 23 when the fourth loop is connected to the fifth loop.

[0074] In the embodiment shown in Figure 1, the thermal management system also includes a heat pump system (not shown) and a chiller system, in which the refrigerant circulates. In the heat pump system, the refrigerant absorbs heat from the environment to form a high-temperature refrigerant, which then exchanges heat with the coolant in the heating heat exchanger 15 to heat the coolant. The heat pump system is ineffective in low-temperature environments and typically requires PTC (Positive Temperature Coefficient) auxiliary heating to further heat the coolant. In the chiller system, a low-temperature refrigerant is typically formed through the compression and subsequent expansion of the refrigerant. This low-temperature refrigerant exchanges heat with the coolant in the first cooling heat exchanger 17 and the second cooling heat exchanger 19 to cool the coolant, which is then used to cool different parts of the vehicle, such as the passenger compartment, the battery, or the drive motor.

[0075] Specifically, the heating heat exchanger 15 can be a water-cooled condenser (WCC).

[0076] In the embodiment shown in Figure 1, both the heater core 21 and the cooler core 23 are located within the passenger compartment. When high-temperature coolant flows from the heating heat exchanger 15 through the first valve 11 to the heater core 21, the cold air in the passenger compartment exchanges heat with the high-temperature coolant, heating the passenger compartment. The coolant, cooled at the heater core 21, flows back to the heating heat exchanger 15 through the first valve 11. When low-temperature coolant flows from the first refrigeration heat exchanger 17 and / or the second refrigeration heat exchanger 19 through the second valve 13 to the cooler core 23, the hot air in the passenger compartment exchanges heat with the low-temperature coolant, cooling the passenger compartment. The coolant, heated at the cooler core 23, flows back to the first refrigeration heat exchanger 17 and / or the second refrigeration heat exchanger 19 through the second valve 13.

[0077] In the embodiment shown in Figure 1, a heater 29 is also provided on the second circuit for heating the coolant in the second circuit. Since heat pump systems are ineffective in low-temperature environments, auxiliary heating can be provided by the heater 29. Specifically, the heater 29 can be a PTC (Potentially Transmitted Chemical) heater.

[0078] In the embodiment shown in Figure 1, the first valve port 101 and the second valve port 102 of the first valve 11 are respectively connected to the coolant inlet / outlet of the heating heat exchanger 15; the third valve port 103 and the fourth valve port 104 of the first valve 11 are respectively connected to the coolant inlet / outlet of the heater core 21; the fifth valve port 105 and the sixth valve port 106 of the second valve 13 are respectively connected to the coolant inlet / outlet of the first refrigeration heat exchanger 17; the seventh valve port 107 and the eighth valve port 108 of the second valve 13 are respectively connected to the coolant inlet / outlet of the second refrigeration heat exchanger 19; and the ninth valve port 109 and the tenth valve port 110 of the second valve 13 are respectively connected to the coolant inlet / outlet of the cooler core 23.

The nineteenth valve port 119 and the twentieth valve port 120 of the first valve 11 are respectively connected to the sixth circuit and the seventh circuit, and the twenty-first valve port 121, the twenty-second valve port 122, and the twenty-third valve port 123 of the third valve 31 are respectively connected to the twenty-fourth valve port 124 of the second valve 13, the fifth circuit, and the twenty-fifth valve port 125 of the second valve 13.

[0082] In the embodiment shown in Figure 1, the thermal management system further includes a degassing bottle 43, one end of which is connected to the radiator 33, and the other end is connected to the pipeline between the third valve 31 and the radiator 33. The degassing bottle 43 is used to remove dissolved gases from the coolant to prevent the formation of bubbles in the coolant.

[0083] In the embodiments shown in Figures 1 and 4, the thermal management system includes a passenger compartment heating function. Under the passenger compartment heating function, the first circuit and the second circuit are connected. Coolant flows from the heating heat exchanger 15 through the first valve 11 to the heater core 21. After the heater core 21 heats the passenger compartment, the coolant flows back to the heating heat exchanger 15 through the first valve 11. This cycle continues. The heat absorbed by the coolant from the refrigerant at the heating heat exchanger 15 is transferred to the heater core 21, and the heater core 21 exchanges heat with the air in the passenger compartment.

[0084] Specifically, the first valve 11 is configured to connect the first valve port 101 and the fourth valve port 104, and connect the second valve port 102 and the third valve port 103 under the crew cabin heating function, thereby connecting the first circuit and the second circuit to form a closed loop.

[0085] In the embodiments shown in Figures 1 and 3, the thermal management system also includes a passenger compartment cooling function. Under the passenger compartment cooling function, the third circuit and the fifth circuit (not shown) are connected through the second valve 13, and / or the fourth circuit and the fifth circuit are connected (as shown in Figure 3). The coolant flows from the first refrigeration heat exchanger 17 and / or the second refrigeration heat exchanger 19 to the cooler core 23 through the second valve 13. After the cooler core 23 cools the passenger compartment, the coolant flows back to the first refrigeration heat exchanger 17 and / or the second refrigeration heat exchanger 19 through the second valve 13. This cycle continues. The coolant absorbs heat at the cooler core 23, thereby cooling the passenger compartment. Then, the coolant transfers heat to the refrigerant at the first refrigeration heat exchanger 17 and / or the second refrigeration heat exchanger 19.

[0086] Specifically, the second valve 13 is configured to connect the fifth valve port 105 and the tenth valve port 110, and the sixth valve port 106 and the ninth valve port 109, thereby connecting the third circuit and the fifth circuit, and / or connect the eighth valve port 108 and the ninth valve port 109, and the seventh valve port 107 and the tenth valve port 110, thereby connecting the fourth circuit and the fifth circuit (as shown in Figure 3).

[0087] In the embodiments shown in Figures 1 and 5, the thermal management system also includes a cabin dehumidification function. During cabin cooling, the first circuit is connected to the second circuit, and the third circuit is connected to the fifth circuit (not shown), and / or the fourth circuit is connected to the fifth circuit (see Figure 5). Coolant flows from the heating heat exchanger 15 through the first valve 11 to the heater core 21. After the heater core 21 heats the cabin, the coolant flows back to the heating heat exchanger 15 through the first valve 11. This cycle repeats, and the coolant transfers the heat absorbed at the heating heat exchanger 15 to the heater core 21. Heater core 21 exchanges heat with the air in the passenger compartment. Simultaneously, coolant flows from the first heat exchanger 17 and / or the second heat exchanger 19 through the second valve 13 to cooler core 23. After cooling the passenger compartment, the coolant flows back to the first heat exchanger 17 and / or the second heat exchanger 19 through the second valve 13. This cycle repeats, and the heat absorbed by the coolant at cooler core 23 is transferred to the first heat exchanger 17 and / or the second heat exchanger 19, where cooler core 23 exchanges heat with the air in the passenger compartment. Since both heater core 21 and heater core 23 exchange heat simultaneously, no cooling or heating effect is produced in the passenger compartment; only a dehumidifying effect is achieved.

[0088] Specifically, the first valve 11 is configured to connect the first valve port 101 and the fourth valve port 104, and the second valve port 102 and the third valve port 103, thereby connecting the first circuit and the second circuit, under the dehumidification function of the crew cabin; the second valve 13 is configured to connect the fifth valve port 105 and the tenth valve port 110, and the sixth valve port 106 and the ninth valve port 109, under the dehumidification function of the crew cabin, thereby connecting the third circuit and the fifth circuit (not shown in the figure); and / or, connect the eighth valve port 108 and the ninth valve port 109, and connect the seventh valve port 107 and the tenth valve port 110, thereby connecting the fourth circuit and the fifth circuit (see Figure 5).

The coolant then flows back from the radiator 33 through the first valve 11 to the heat exchanger 15. This cycle continues. The coolant absorbs heat from the high-temperature refrigerant at the heat exchanger 15 and then discharges the heat to the environment through the radiator 33.
