[0045] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0046] Reference below Figure 1-Figure 8 The cooling structure provided in the embodiment of the present application is described. The cooling structure is installed on a vehicle body and includes a heat exchange module 110 , a condenser 120 and a fan 130 .

[0047] Unless otherwise specified, the front-to-back direction in the present application is the longitudinal direction of the vehicle, that is, the first horizontal direction; the left-right direction is the lateral direction of the vehicle, that is, the second horizontal direction; and the up-down direction is the vertical direction of the vehicle.

[0048] The heat exchange module 110 includes a high temperature chamber 111 and a low temperature chamber 112 which are integrated, and the high temperature chamber 111 and the low temperature chamber 112 are arranged at intervals in the vertical direction.

[0049] It should be noted that if Figure 2As shown, the heat exchange module 110 includes a mounting frame 1101 and a plurality of heat dissipation pipes 1102. The mounting frame 1101 is mounted on the vehicle body, and each heat dissipation pipe 1102 is provided with a plurality of heat sinks. A portion of the plurality of heat dissipation pipes 1102 is arranged on the mounting frame 1101 and forms a high-temperature cavity 111 having a first flow channel, and another portion of the plurality of heat dissipation pipes 1102 is arranged on the mounting frame 1101 and forms a low-temperature cavity 112 having a second flow channel, and the first flow channel and the second flow channel are independent of each other, the first flow channel is used to be connected to the engine 500 to form a first heat dissipation circuit to dissipate heat from the engine 500, and the second flow channel is used to be connected to the heating element 200 to form a second heat dissipation circuit to dissipate heat from the heating element 200, and the heating element 200 includes but is not limited to a transmission oil cooler (Transmission Oil Cooler, TOC), a powertrain control module (Powertrain Control Module, PCM), an advanced driver assistance controller unit (Advanced Driver Assistance Controller Unit, ADCU) and a motor, etc.

[0050] It is understandable that the use of the integrated high-temperature chamber 111 and the low-temperature chamber 112 to replace the high-temperature radiator and the low-temperature radiator in the related art can avoid the cumbersome disassembly and assembly, and because the airflow passes through the condenser 120, the heat exchange module 110 and the fan 130 from front to back in sequence, compared with the related art in which the airflow passes through the condenser 120, the high-temperature radiator, the low-temperature radiator and the fan 130 from front to back in sequence, the number of parts that the airflow passes through in the front-to-back direction is reduced, the wind resistance and noise are reduced, and the user experience is improved. In addition, since the high-temperature chamber 111 and the low-temperature chamber 112 are arranged at intervals in the vertical direction, the airflow flow distance can be reduced, and based on the principle of natural rise of hot air, the low-temperature air and the high-temperature air will not mix during the flow process, thereby helping to form a smoother air flow path, improve heat exchange efficiency, and reduce the overall size of the cooling structure in the front-to-back direction, thereby improving space utilization.

[0051] The condenser 120 and the heat exchange module 110 are arranged at intervals along the first horizontal direction. It is understandable that the condenser 120 is installed on the vehicle body and located in front of the heat exchange module 110, and is used to dissipate heat from the vehicle's air conditioning system. It should be noted that the distance between the condenser 120 and the heat exchange module 110 along the front-to-back direction can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0052] The fan 130 is arranged at intervals on a side of the heat exchange module 110 away from the condenser 120. It is understandable that the cooling fan 130 is installed on the vehicle body and is located behind the heat exchange module 110, and is used to draw the low-temperature air at the front end to the rear of the fan 130 during the operation of the vehicle, so as to use the airflow to take away the heat of the condenser 120 and the heat exchange module 110. It should be noted that the distance between the fan 130 and the heat exchange module 110 in the front-to-back direction can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0053] According to the cooling structure provided in the embodiment of the present application, the integrated high-temperature chamber 111 and the low-temperature chamber 112 can avoid cumbersome disassembly and assembly, reduce wind resistance and noise, improve user experience, improve heat exchange efficiency, and reduce the overall size of the cooling structure along the front and rear directions, thereby improving space utilization.

[0054] In some embodiments, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the high temperature chamber 111 is located above the low temperature chamber 112 , and the projection of at least part of the condenser 120 along the first horizontal direction is located within the projection of the low temperature chamber 112 along the first horizontal direction.

[0055] It is understandable that by arranging the high temperature chamber 111 above the low temperature chamber 112, based on the principle that hot air naturally rises, natural convection can be fully utilized to improve the cooling efficiency. At the same time, since the condenser 120 is partially located in the projection of the low temperature chamber 112 along the front-to-back direction, part of the airflow does not need to pass through the condenser 120 and directly passes through the low temperature chamber 112, thereby further improving the cooling efficiency.

[0056] It should be noted that, in some embodiments, the lower surface of the condenser 120 may be lower than or equal to the lower surface of the low-temperature chamber 112, and the upper surface of the condenser 120 may be lower than the upper surface of the low-temperature chamber 112; in some other embodiments, the lower surface of the condenser 120 may be higher than the lower surface of the low-temperature chamber 112. This embodiment does not impose any specific restrictions on this. As long as the condenser 120 can be partially located in the projection of the low-temperature chamber 112 along the front-to-back direction, part of the airflow can pass directly through the low-temperature chamber 112 without passing through the condenser 120, thereby further improving the cooling efficiency.

[0057] In some embodiments, Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the top surface of the condenser 120 is lower than the top surface of the heat exchange module 110 , and the bottom surface of the condenser 120 is higher than the bottom surface of the heat exchange module 110 .

[0058] It should be noted that since the upper surface of the condenser 120 is lower than the upper surface of the heat exchange module 110 and the lower surface of the condenser 120 is higher than the lower surface of the heat exchange module 110, it helps that the high-temperature air can rise from the condenser 120 and be further cooled by the heat exchange module 110, forming a natural thermal gradient, while reducing the resistance to air flow and further improving the heat exchange effect.

[0059] The present application also provides a thermal management system, which is installed on the vehicle body. Figures 1 to 8 As shown, the thermal management system includes an engine 500, a heating element 200 and the above-mentioned cooling structure.

[0060] The engine 500 is connected to the high temperature chamber 111 through the high temperature heat dissipation pipeline 600 to form a first heat dissipation loop. The heating element 200 is connected to the low temperature chamber 112 through the low temperature heat dissipation pipeline 300 to form a second heat dissipation loop. It should be noted that the heating element 200 includes but is not limited to a TOC, a PCM, an ADCU and a motor connected in series in sequence.

[0061] It can be understood that since the temperatures generated by the engine 500 and the heating element 200 are different when they are working, the high-temperature chamber 111 and the low-temperature chamber 112 are used to realize two independent heat dissipation circuits (a first heat dissipation circuit and a second heat dissipation circuit), so that the cooling requirements of each circuit can be independently controlled, the cooling efficiency can be improved, and the effect of energy saving and cost reduction can be achieved.

[0062] According to the thermal management system provided in the embodiment of the present application, the high-temperature chamber 111 and the low-temperature chamber 112 integrated in the heat exchange module 110 can avoid tedious disassembly and assembly, reduce wind resistance and noise, improve user experience, improve heat exchange efficiency, and reduce the overall size of the cooling structure along the front and rear directions, thereby improving space utilization.

[0063] In some embodiments, Figures 1 to 8 As shown, the thermal management system further includes two heat exchangers connected in series, and the two heat exchangers are arranged opposite to each other along the second horizontal direction, and the cooling structure is located between the two heat exchangers.

[0064] It can be understood that the two heat exchange components are arranged opposite to each other in the left-right direction and are respectively close to the two wheels at the front end of the vehicle to play a role of pre-cooling or after-cooling, thereby improving the heat exchange efficiency while avoiding obstruction to air flow.

[0065] In some embodiments, Figures 1 to 4 As shown, the engine 500 includes a turbocharged engine, and the heat exchange element includes an air-to-air intercooler 410 , which is connected to the engine 500 via an air pipe 411 .

[0066] It is understandable that the compressed air temperature entering the turbocharged engine is lowered by air cooling through the air-to-air intercooler 410, thereby increasing the power output and combustion efficiency of the engine 500 and the rotation speed of the turbine. Of course, in other embodiments, a water-cooled intercooler may also be used, that is, a water-cooled method (the high-temperature chamber 111, the water-cooled intercooler and the engine 500 are connected end to end through the high-temperature heat dissipation pipeline 600 to form a first heat dissipation circuit) is used to improve the heat dissipation efficiency, and this embodiment does not impose specific restrictions on this.

[0067] In some embodiments, Figures 5 to 8 As shown, the engine 500 includes a naturally aspirated engine, and the heat exchange element includes a radiator 420, which is connected to the low temperature chamber 112 through a low temperature heat dissipation pipeline 300 to further improve the heat dissipation efficiency. The radiator 420 includes but is not limited to a water-cooled radiator.

[0068] In some embodiments, Figure 7 As shown, the low temperature chamber 112, the radiator 420, the heating element 200 and another radiator 420 are connected end to end in sequence through the low temperature heat dissipation pipeline 300 to form a second heat dissipation loop.

[0069] It can be understood that the low-temperature chamber 112, the radiator 420, the heating element 200 and another radiator 420 are connected end to end in sequence through the low-temperature heat dissipation pipeline 300 to form a second heat dissipation circuit, that is, the low-temperature chamber 112 and the radiator 420 are connected in series to facilitate the layout of the low-temperature heat dissipation pipeline 300, which is convenient for disassembly and assembly and has low cost.

[0070] In some embodiments, Figure 8 As shown, the low-temperature chamber 112 and the two radiators 420 are connected end to end in sequence through a portion of the low-temperature heat dissipation pipeline 300 to form a first closed loop, and the low-temperature chamber 112 and the heating element 200 are connected end to end in sequence through another portion of the low-temperature heat dissipation pipeline 300 to form a second closed loop. The second heat dissipation loop includes the first closed loop and the second closed loop.

[0071] It can be understood that the low-temperature chamber 112 and the two radiators 420 are connected end to end in sequence through a portion of the low-temperature heat dissipation pipeline 300 to form a first closed loop, and the low-temperature chamber 112 and the heating element 200 are connected end to end in sequence through another portion of the low-temperature heat dissipation pipeline 300 to form a second closed loop, that is, the radiator 420 and the heating element 200 are connected in parallel to further improve the heat dissipation efficiency, achieve more precise temperature control, and facilitate maintenance.

[0072] The embodiment of the present application further provides a vehicle, which includes a vehicle body and the above-mentioned thermal management system, wherein the thermal management system is installed on the vehicle body.

[0073] According to the vehicle provided in the embodiment of the present application, the high-temperature chamber 111 and the low-temperature chamber 112 integrated in the heat exchange module 110 of the thermal management system can avoid tedious disassembly and assembly, reduce wind resistance and noise, improve user experience, improve heat exchange efficiency, and reduce the overall size of the cooling structure along the front and rear directions, thereby improving space utilization.
