DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0048] This application proposes a thermal management system. Figures 1 to 10 These are some embodiments of the present application.

[0049] See also Figure 1 to Figure 2 In some embodiments of the present application, the thermal management system includes a compressor 1 and a plurality of first heat exchange components 20, and the plurality of first heat exchange components 20 are all connected to the compressor 1; that is, in this embodiment, the compressor 1 can realize the circulation of the refrigerant in the thermal management system, that is, the compressor 1 can inhale low-temperature and low-pressure refrigerant gas and discharge high-temperature and high-pressure refrigerant gas, and the first heat exchange component 20 is connected to the compressor 1, so that the compressor 1 can transport the refrigerant to the first heat exchange component 20, thereby enabling the first heat exchange component 20 to exchange heat with the external environment.

[0050] In some embodiments of the present application, multiple first heat exchange components 20 are connected in parallel and are configured to perform heat exchange on different areas in the vehicle; wherein the multiple first heat exchange components 20 cooperate with each other to cover the heat exchange needs of various parts in the vehicle.

[0051] In the technical solution of the present application, a plurality of first heat exchange components 20 connected in parallel to the compressor 1 are provided in the thermal management system, so that each first heat exchange component 20 and the compressor 1 have an independent channel for transporting refrigerant. Therefore, the flow rate of the refrigerant transported to the plurality of first heat exchange components 20 can be independently adjusted, so that the driver and passengers can control the thermal management system according to the temperature requirements of the area where they are located to meet the comfort experience of the driver and passengers.

[0052] It can be understood that in some embodiments of the present application, if the thermal management system performs a cooling operation on the interior of the vehicle, the first heat exchange component 20 corresponding to the driver area and the first heat exchange component 20 corresponding to the passenger area can be controlled separately, so that the interior temperature of the vehicle corresponding to the driver area meets the first temperature, and the temperature of the vehicle corresponding to the passenger area meets the second temperature, so as to respectively meet the actual experience requirements of the driver and the passengers.

[0053] At the same time, when the thermal management system controls the temperature of the passenger compartment, the first heat exchange component 20 in the area corresponding to the unmanned position in the vehicle does not work, thereby achieving a certain energy-saving effect.

[0054] In addition, multiple first heat exchange components 20 respectively correspond to unused areas in the vehicle for heat exchange; in one embodiment, one first heat exchange component 20 can correspond to one or more seat positions; in another embodiment, one first heat exchange component 20 can correspond to different areas in the vehicle, such as the cockpit, passenger compartment, trunk and other areas for independent temperature control.

[0055] It should be noted that since the thermal management system in the embodiment of the present application includes multiple first heat exchange components 20, the multiple first heat exchange components 20 adopt a modular design and are connected in parallel with each other, which is not only convenient for maintenance and replacement in the thermal management system, but also can be adapted to different vehicle models; for example, in one embodiment of the present application, when the thermal management system is used in a sedan, four first heat exchange components 20 can be provided; in another embodiment of the present application, when the thermal management system is used in a sports utility vehicle, six first heat exchange components 20 can be provided.

[0056] Similarly, the modularly designed first heat exchange component 20 has a high degree of standardization, so it is highly replaceable, has high installation efficiency in the vehicle, and has high scalability. Heat exchange control in multiple temperature zones in the vehicle can be easily achieved by expanding multiple first heat exchange components 20 in the vehicle.

[0057] At the same time, the modularly designed first heat exchange component 20 gets rid of the dependence of the thermal management system in the related art on the air-conditioning box and the air outlet duct, which can shorten the development cycle and save the development cost of different project vehicles.

[0058] In some embodiments of the present application, the first heat exchange component 20 includes a heat exchanger 201 and a heater 202, and the two ends of the heat exchanger 201 are respectively connected to the two ends of the compressor 1; the heater 202 is arranged on one side of the heat exchanger 201 and is configured to heat the air in the vehicle; wherein, a refrigerant can be introduced into the heat exchanger 201, so as to perform heat exchange with the interior environment of the vehicle, that is, to heat up or cool down the interior environment of the vehicle, and the heater 202 can heat the air in the vehicle; in this embodiment, if the interior environment of the vehicle is at a low temperature and high humidity, the heat exchanger 201 can cool down and dehumidify the air in the vehicle, and at the same time, the heater 202 works to heat the air in the vehicle to meet the heating needs in the vehicle at the same time, so the first heat exchange component 20 has a dehumidification function to avoid fogging on the inner surface of the vehicle's glass and affecting the driving safety of the vehicle.

[0059] In addition, the heater can also assist in heating the air inside the vehicle when the thermal management system heats the vehicle interior.

[0060] In some embodiments of the present application, the first heat exchange component 20 also includes a first fan 203, which is located on one side of the heat exchanger 201. The first fan 203 can circulate the air in the vehicle to improve the efficiency and effect of heat exchange between the first heat exchange component 20 and the air in the vehicle.

[0061] In some embodiments of the present application, the heater 202 is a PTC heater; wherein the PTC heater transfers heat to the air inside the vehicle through heat dissipation fins.

[0062] In some embodiments of the present application, the heater 202 is a heater core, which can provide warm air to the interior of the vehicle.

[0063] In some embodiments of the present application, the thermal management system can be applied to fuel vehicles, plug-in hybrid vehicles or new energy vehicles.

[0064] In some embodiments of the present application, the thermal management system also includes a second heat exchange component 4, both ends of which are respectively connected to the two ends of the compressor 1, and are configured to perform heat exchange with the battery of the vehicle; that is, in this embodiment, the thermal management system can also perform heat exchange with the battery pack in the vehicle.

[0065] In some embodiments of the present application, the second heat exchange component 4 includes a battery cold plate. Compared with the related art that temperature control of the battery pack in the vehicle requires a separate coolant circulation water circuit, which has the technical defects of complex system layout and difficult maintenance and overhaul, in the present application, the refrigerant can directly cool or heat the battery pack through the battery cold plate, without the need for additional heating film or independent battery liquid cooling device. The system solution is simple and easy to maintain and overhaul.

[0066] In some embodiments of the present application, the second heat exchange component 4 includes multiple layers of cold plates, that is, heat exchange between the thermal management system and the battery pack can be achieved through the multiple layers of cold plates.

[0067] In some embodiments of the present application, the second heat exchange component 4 and the multiple first heat exchange components 20 are connected in parallel; that is, in this embodiment, the second heat exchange component 4 and the multiple first heat exchange components 20 are connected in parallel so that the second heat exchange component 4 and the multiple first heat exchange components 20 can both be independently temperature controlled without affecting each other, thereby enabling flexible temperature control according to different conditions of the vehicle.

[0068] In some embodiments of the present application, the thermal management system includes a second heat exchange component 4 and multiple first heat exchange components 20 connected in parallel, which can achieve independent control of multiple temperature zones in the vehicle while taking into account the thermal management needs of the battery. Through the combination of various parallel modules (the first heat exchange component 20 and the second heat exchange component 4), a variety of working modes can be achieved to cover the year-round environmental conditions of the vehicle. The environmental adaptability, reliability, and comfort of the thermal management system are good, and the thermal management system has a simple layout, high overall thermal efficiency, high scalability, convenient maintenance and repair, and easy platform promotion.

[0069] In some embodiments of the present application, the thermal management system also includes at least one condenser 5; wherein the condenser 5 is connected to the outlet of the compressor 1 and the inlet of at least one first heat exchange component 20; that is, in this embodiment, the condenser 5 can dissipate the heat and cool the high-temperature and high-pressure refrigerant gas discharged from the compressor into a high-pressure medium-temperature refrigerant liquid, and then allow the high-pressure medium-temperature refrigerant liquid to enter the first heat exchange component 20 to dissipate heat and cool the air inside the vehicle.

[0070] In some embodiments of the present application, the outlet of the condenser 5 and the compressor 1 are connected to the inlet of the second heat exchange component 4 so as to discharge the refrigerant into the second heat exchange component 4 to dissipate heat and cool the battery pack.

[0071] There may be one or more condensers 5. In one embodiment, when there is one condenser 5, the outlet of the condenser is connected to the inlets of the first heat exchange components 20 and the second heat exchange components 4; when there are multiple condensers 5, the multiple condensers 5 can be connected to the multiple first heat exchange components 20 and the second heat exchange components 4 in a one-to-one correspondence.

[0072] In some embodiments of the present application, the thermal management system further includes a second fan, which is located on one side of the condenser. The second fan can assist in dissipating heat for the refrigerant in the condenser.

[0073] In some embodiments of the present application, the thermal management system also includes at least one first channel 6, which is connected to the outlet of the compressor 1 and the inlet of at least one first heat exchange component 20, and is connected in parallel with the condenser 5; that is, in this embodiment, when the passenger compartment and / or battery pack of the vehicle needs to be heated, the high-temperature and high-pressure refrigerant gas discharged from the compressor 1 can enter the first heat exchange component 20 and / or the second heat exchange component 4 through the first channel 6, thereby heating the air in the passenger compartment and / or the battery pack.

[0074] Therefore, in the above embodiment, when the passenger compartment and / or battery pack of the vehicle needs to be heated, the high-temperature and high-pressure refrigerant gas discharged from the compressor 1 enters the first heat exchange component 20 and / or the second heat exchange component 4 through the first channel 6; when the passenger compartment and / or battery pack of the vehicle needs to be cooled, the high-temperature and high-pressure refrigerant gas discharged from the compressor 1 passes through the condenser 5 and then enters the first heat exchange component 20 and / or the second heat exchange component 4. Such a design can avoid the problem in the related art that the heat source of the vehicle in winter heating is the air source, and the condenser 5 located outside the vehicle will be frosted due to the low outdoor ambient temperature, resulting in poor heating capacity of the thermal management system, and poor heating effect during defrosting directly affects the comfort of the air conditioner.

[0075] At the same time, there is no need to use the condenser 5 located outside the vehicle, and the defrosting of the condenser 5 in the related art needs to be additionally arranged with a corresponding defrosting system, which leads to the disadvantages of complex structure and high cost of the thermal management system.

[0076] In some embodiments of the present application, the thermal management system further includes a third heat exchange component 7, which is connected to the inlet of the compressor 1 and the outlet of at least one first heat exchange component 20, and is configured to perform heat exchange with the vehicle's drive system 18. The third heat exchange component 7 can be provided to allow the refrigerant that has been liquefied by the first heat exchange component 20 and / or the second heat exchange component 4 to absorb the residual heat of the drive system 18 and then vaporize before entering the compressor 1, thereby preventing the liquid refrigerant from entering the compressor 1 and causing damage to the compressor 1.

[0077] In some embodiments of the present application, the drive system 18 includes an engine and / or an electric motor.

[0078] In some embodiments of the present application, the thermal management system also includes at least one second channel 8, which is connected to the outlet of the first heat exchange component 20 and the inlet of the compressor 1 and is connected in parallel with the second heat exchange component 4; in this embodiment, when the vehicle is in the passenger compartment and / or battery pack cooling mode, the refrigerant of the compressor 1 passes through the condenser 5, then passes through the first heat exchange component 20 and / or the second heat exchange component 4, and then flows back to the compressor 1 through the second channel 8; when the vehicle is in the passenger compartment and / or battery pack heating mode, the refrigerant of the compressor 1 passes through the first channel 6, then passes through the first heat exchange component 20 and / or the second heat exchange component 4, and then flows back to the compressor 1 through the third heat exchange component 7.

[0079] That is, the outlet of the compressor 1 is connected to the condenser 5 and the first channel 6 respectively, and the inlet of the compressor is connected to the third heat exchange component 7 and the second channel 8 respectively, so as to meet the cooling and heating requirements of the thermal management system proposed in this application.

[0096] The thermal management system proposed in the embodiment of the present application can enable the vehicle to operate under the following working conditions.

[0097] The vehicle is in passenger compartment cooling mode

[0098] See also Figure 4 The circulation route of the refrigerant is as follows: the high-temperature and high-pressure refrigerant gas is discharged from the outlet of the compressor 1, and enters the condenser 5 for heat dissipation and cooling after passing through the second valve body 10. The cooled high-pressure and medium-temperature refrigerant liquid is throttled by the third valve body 11 and becomes a low-temperature and low-pressure two-phase refrigerant, which enters the heat exchanger 201 for heat exchange with the air in the vehicle. The refrigerant evaporates and absorbs heat to cool down.

[0106] The vehicle is in battery heating mode

[0107] See also Figure 8The circulation route of the refrigerant is as follows: the high-temperature and high-pressure refrigerant gas is discharged from the outlet of the compressor 1, passes through the first channel 6 and the first valve body 9 on the first channel 6, and then flows to the eighth valve body 16. The eighth valve body 16 controls the temperature of the high-temperature and high-pressure refrigerant gas and enters the second heat exchange component 4 to heat the battery pack. After being cooled by the third heat exchange component 7, the refrigerant is throttled by the tenth valve body. The throttled refrigerant enters the third heat exchange component 7 through the eighth valve body 16 to absorb the waste heat of the drive system 18, and then vaporizes and passes through the gas-liquid separator 19, and is finally sucked into the inlet of the compressor 1 to realize a set of cycles of the refrigerant in the thermal management system.

[0108] The vehicle is in passenger compartment heating mode and battery heating mode

[0109] See also Fig. 9 The circulation route of the refrigerant is as follows: the high-temperature and high-pressure refrigerant gas is discharged from the outlet of the compressor 1, and is divided into two paths after passing through the first channel 6 and the first valve body 9; one path passes through the third valve body 11 and flows into the heat exchanger 201 to exchange heat with the air in the vehicle, and the other path passes through the fourth valve body 12 for throttling and temperature control, enters the second heat exchange component 4, and then passes through the fifth valve body 13 for throttling. The two refrigerants merge with each other and enter the third heat exchange component 7 through the eighth valve body 16 to absorb the waste heat of the drive system 18, and then vaporize and pass through the gas-liquid separator 19, and finally are sucked into the inlet of the compressor 1 to realize a set of cycles of the refrigerant in the thermal management system.

[0110] The heater 202 supplements the temperature in the passenger compartment according to demand during the heating process.

[0111] The vehicle is in dehumidification mode

[0112] See also Fig.10 The refrigerant flow route is as follows: the high-temperature and high-pressure refrigerant gas discharged from the outlet of the compressor 1 passes through the second valve body 10 and enters the condenser 5 for heat dissipation and cooling.

[0113] The cooled high-pressure and medium-temperature refrigerant liquid is throttled by the third valve body 11 and becomes a low-temperature and low-pressure two-phase refrigerant, which enters the heat exchanger 201 for heat exchange with the air in the vehicle. The refrigerant evaporates to cool and dehumidify. The low-temperature and low-pressure gaseous refrigerant coming out of the heat exchanger 201 passes through the ninth valve body 17 and returns to the gas-liquid separator 19, and is finally sucked into the inlet of the compressor 1, so as to realize a set of circulation of the refrigerant in the thermal management system.

[0114] The heater 202 heats the dehumidified circulating air to meet the heating requirements of the passenger compartment.

[0115] It should be noted that when the vehicle is in the initial stage of the passenger compartment heating mode, the temperature of the refrigerant is relatively low. At this time, the heater 202 intervenes to assist in heating, thereby increasing the heating rate of the thermal management system. After the temperature of the refrigerant rises, the proportion of heat generated by the third heat exchange component 7 and the drive system 18 in the thermal management system gradually increases, and the third heat exchange component 7 gradually reduces its power until it exits heating, thereby taking into account the energy consumption and comfort of the thermal management system.
