[0036] The following reference Figures 1-7Describe the radiator assembly 100 according to an embodiment of the present utility model. By setting the area of the front windward surface 21 of the condenser to be larger than the area of the front windward surface 11 of the medium-temperature radiator, and the ratio between the two being 1.2 to 1.5, the heat dissipation efficiency of the medium-temperature radiator 1, the condenser 2, and the high-temperature radiator 3 can be improved respectively. Furthermore, the working heat dissipation capacity of the motor, the battery, and the engine, as well as the refrigeration capacity of the air conditioner, can be enhanced, thus improving the working performance of the radiator assembly 100.

[0037] As Figures 1-7 shown, the radiator assembly 100 according to an embodiment of the present utility model includes: a medium-temperature radiator 1, a condenser 2, and a high-temperature radiator 3.

[0038] The medium-temperature radiator 1 is used to communicate with the electric drive heat exchange circuit and / or the battery circuit. The condenser 2 is used to communicate with the air-conditioning circuit. The high-temperature radiator 3 is used to communicate with the engine heat exchange circuit. That is to say, the heat of the electric drive heat exchange circuit and / or the battery circuit can be dissipated through the medium-temperature radiator 1. The condenser 2 can exchange heat with the refrigerant in the air-conditioning circuit, and the heat of the engine heat exchange circuit can be dissipated through the high-temperature radiator 3.

[0039] Specifically, the medium-temperature radiator 1 communicates with the electric drive heat exchange circuit, and the electric drive heat exchange circuit is connected to a motor drive system. When the motor drive system operates, heat is generated. A medium flows in the electric drive heat exchange circuit. After the medium in the electric drive heat exchange circuit absorbs the heat of the motor drive system, it flows to the medium-temperature radiator 1 and is dissipated through the medium-temperature radiator 1 to achieve heat dissipation of the motor drive system. And / or, the medium-temperature radiator 1 can also communicate with the battery circuit. The battery circuit is connected to the outside of the battery. The medium in the battery circuit absorbs the heat of the battery and then flows to the medium-temperature radiator 1 for heat exchange and cooling through the medium-temperature radiator 1.

[0040] Moreover, the medium-temperature radiator 1 can selectively communicate with the electric drive heat exchange circuit and the battery circuit, that is, the medium-temperature radiator 1 can dissipate heat from the electric drive and the battery separately, or the medium-temperature radiator 1 can dissipate heat from the electric drive and the battery simultaneously to ensure the safe operation of the electric drive and the battery. And the battery circuit is also used to heat the battery. Wherein, the medium can be set as cooling water, etc.

[0041] The high-temperature radiator 3 communicates with the engine heat exchange circuit. The engine heat exchange circuit is connected to an engine system. Cooling water flows in the engine heat exchange circuit. When the engine operates, heat is generated. The cooling water in the engine heat exchange circuit absorbs the heat of the engine and then flows to the high-temperature radiator 3 for heat exchange and cooling. And through the circulating cooling of the high-temperature radiator 3 and the engine heat exchange circuit, the reliable operation of the engine is ensured.

[0042] The condenser 2 is connected to the air-conditioning circuit. There is a medium in the air-conditioning circuit. The air-conditioning circuit is connected to a compressor, an evaporator, etc. The compressor, the condenser 2 and the evaporator are connected. The medium flows through the compressor, the condenser 2 and the evaporator. By exchanging heat between the air and the medium in the condenser 2 and between the medium in the evaporator and the air, the refrigeration or heating of the air conditioner can be achieved. Among them, the medium can be set as a refrigerant.

[0043] Among them, the medium-temperature radiator 1 is installed at the front grille of the vehicle, and the condenser 2 and the high-temperature radiator 3 are installed behind the medium-temperature radiator 1 in sequence along the front-rear direction.

[0044] Specifically, the radiator assembly 100 can be arranged in the front space of the vehicle and is detachably connected to the rear side area of the front grille of the vehicle. Among them, the medium-temperature radiator 1, the condenser 2 and the high-temperature radiator 3 are connected in sequence along the front-rear direction, and the three can be integrated into one body to improve the structural compactness. And the medium-temperature radiator 1 is located at the rear side of the front grille of the vehicle, and the front grille allows air to flow through. In this way, a large amount of air can directly enter the medium-temperature radiator 1 through the front grille to achieve air-cooled heat dissipation, and the heat dissipation effect is better. And the condenser 2 and the high-temperature radiator 3 are located behind the medium-temperature radiator 1 in sequence, which can realize the refrigeration of the air conditioner and the heat dissipation of the engine. And when the three work simultaneously, it can avoid the influence of the heat dissipation of the condenser 2 and the high-temperature radiator 3 on the medium-temperature radiator 1, and thus can ensure their respective heat dissipation requirements. And the front grille can also protect the front part of the vehicle from being hit by objects such as stones and insects, reducing damage to other structures such as the radiator assembly 100 and the engine.

[0045] The area of the front windward surface 21 of the condenser is larger than the area of the front windward surface 11 of the medium-temperature radiator. The ratio of the area of the front windward surface 21 of the condenser to the area of the front windward surface 11 of the medium-temperature radiator is 1.2 - 1.5.

[0046] Specifically, the front side surface of the medium-temperature radiator 1 is its front windward surface, the front side surface of the condenser 2 is its front windward surface, and the area of the front windward surface 21 of the condenser is larger than the area of the front windward surface 11 of the medium-temperature radiator. And the area ratio can be 1.2, 1.3, 1.5, etc. By setting the area ratio of the two, the heat dissipation efficiency of the medium-temperature radiator 1 is high, which can meet the heat dissipation requirements of the electric drive and the battery for the medium-temperature radiator 1, and the heat dissipation efficiency of the condenser 2 is also high, which can also meet the heat dissipation requirements of the air-conditioning circuit. In this way, better performance distribution can be obtained to improve the heat dissipation capacity of the radiator assembly 100. And the area ratio of the two can also be set to other ratios, not limited to the above, and can be set according to the size of the front installation space of the vehicle. On the premise of reasonable layout, as long as the heat dissipation requirements can be effectively improved.

[0047] Among them, the front side of the high-temperature radiator 3 can be the same as the front side of the condenser 2, which can ensure the neat structure of the radiator assembly 100, improve the heat dissipation efficiency of the high-temperature radiator 3, and further improve the heat dissipation of the engine to ensure the reliable operation of the engine.

[0048] For the radiator assembly 100 according to the embodiment of the present utility model, by setting the area of the front windward surface 21 of the condenser to be larger than the area of the front windward surface 11 of the medium-temperature radiator, the heat dissipation efficiencies of the medium-temperature radiator 1, the condenser 2, and the high-temperature radiator 3 can be respectively improved, and further the heat dissipation capabilities of the motor, the battery, and the engine as well as the refrigeration capacity of the air conditioner can be enhanced, improving the working performance of the radiator assembly 100 and having a better use effect.

[0049] In some embodiments, the front windward surface 21 of the condenser includes an upper windward area 211 and a lower windward area 212 connected in the up-down direction. The upper windward area 211 and the front windward surface 11 of the medium-temperature radiator are distributed facing each other in the front-back direction, and the lower windward area 212 and the front windward surface 11 of the medium-temperature radiator are distributed offset in the front-back direction.

[0050] Specifically, as Figure 1 and Figure 7 shown, the medium-temperature radiator 1 is located above the front of the condenser 2. The condenser 2 is flush with the tops of the medium-temperature radiator 1 and the high-temperature radiator 3, and the bottom of the condenser 2 protrudes from the bottom of the medium-temperature radiator 1, that is, the lower part area of the condenser 2 is not blocked by the medium-temperature radiator 1. Among them, the front windward surface 21 of the condenser includes an upper windward area 211 and a lower windward area 212. The upper windward area 211 and the front windward surface 11 of the medium-temperature radiator are distributed facing each other, and the area of the upper windward area 211 can be the same as the area of the front windward surface 11 of the medium-temperature radiator, which can make the air in the medium-temperature radiator 1 directly flow to the condenser 2, thereby effectively taking away heat and improving the heat dissipation efficiencies of the medium-temperature radiator 1 and the condenser 2.

[0051] The lower windward area 212 and the front windward surface 11 of the medium-temperature radiator are offset in the front-back direction, and the lower windward area 212 is located below the front windward surface 11 of the medium-temperature radiator. With such a setting, air can directly enter the condenser 2 from the front grille to directly cool the refrigerant in the condenser 2, and the mutual interference between the medium-temperature radiator 1 and the condenser 2 can be avoided, improving the heat dissipation capacity of the condenser 2. Moreover, the area of the lower windward area 212 can be smaller than the area of the front windward surface 11 of the medium-temperature radiator, which can reduce the overall structure of the condenser 2 without affecting the heat dissipation requirements of the condenser 2.

[0052] Thus, through the above spatial setting, the condenser 2 and the medium-temperature radiator 1 make more effective use of space in a limited space while maintaining their respective cooling efficiencies.

[0053] Among them, it should be noted that the radiator assembly 100 further includes an air deflector 7. The air deflector 4 has a guiding effect on the air flow. As Figure 7 shown, the air deflector 4 is installed on the front side of the medium-temperature radiator 1, and the air deflector 4 is located behind the front grille. The air deflector 4 has an air inlet 41 and an air outlet 42 distributed in the front-rear direction. At least part of the inner top wall of the air outlet 42 is configured to be inclined upward from front to back and the upper end is connected to the top of the medium-temperature radiator 1. With such a setting, the air in the upper side area of the air deflector 4 can be introduced into the medium-temperature radiator 1. At least part of the inner bottom wall of the air outlet 42 is configured to be inclined downward from front to back and the lower end is connected to the bottom of the condenser 2. With such a setting, the air in the lower side area of the air deflector 4 can be introduced into the condenser 2. And through the above structural arrangement, the outer periphery of the air outlet 42 is connected to the radiator assembly 100, and the air deflector 4 is hermetically connected to the radiator assembly 100, improving the reliability of the connection between the two. And when the air enters the air deflector 4 from the air inlet 41 and enters the medium-temperature radiator 1 and the condenser 2 from the air outlet 42 of the air deflector 4, the heat dissipation of the medium-temperature radiator 1 and the condenser 2 is realized.

[0054] Thus, by setting the air deflector 4, the air flow direction can be controlled, so that more air is guided by the air deflector 4 and enters the medium-temperature radiator 1 and the condenser 2, improving the utilization rate of the air.

[0055] In some embodiments, the ratio of the left-right width to the up-down height of the medium-temperature radiator 1 is 1.9 - 2.5, that is, the left-right width of the medium-temperature radiator 1 is different from its up-down height, and the left-right width of the medium-temperature radiator 1 is greater than its up-down height, and the ratio between the two can be 1.9, 2.2, 2.5, etc. By setting the above several values, after the air enters the medium-temperature radiator 1, the air flow distribution in the horizontal direction is greater than the air flow distribution in the vertical direction, and the air flow is more evenly distributed in the medium-temperature radiator 1, thereby improving the heat dissipation efficiency of the medium-temperature radiator 1.

[0056] In some other embodiments, the ratio of the left-right width to the up-down height of the condenser 2 is 1.5 - 2.0, that is, the left-right width of the condenser 2 is different from its up-down height, and the left-right width of the condenser 2 is greater than its up-down height, and the ratio between the two can be 1.5, 1.8, 2.0, etc. By setting the above several values, after the air enters the condenser 2, the air flow distribution in the horizontal direction is greater than the air flow distribution in the vertical direction, and the air flow is more evenly distributed in the condenser 2, thereby improving the heat dissipation efficiency of the condenser 2.

[0057] Moreover, the left - right width of the medium - temperature radiator 1 and the condenser 2 corresponds to the transverse direction of the vehicle, and the up - down height of the medium - temperature radiator 1 and the condenser 2 corresponds to the vertical direction of the vehicle. Through the above - mentioned proportional setting, the medium - temperature radiator 1 and the condenser 2 can be more appropriately installed in the installation space at the front end of the vehicle. In this way, not only can their respective heat - dissipation requirements be met, but also the installation requirements of the medium - temperature radiator 1 and the condenser 2 can be satisfied. Moreover, the structures of the medium - temperature radiator 1 and the condenser 2 are not limited to those described in this embodiment and can be flexibly set according to the size of the installation space.

[0058] In some embodiments, the left - right width of the medium - temperature radiator 1 is the same as the left - right width of the condenser 2, which can make the external structures of the medium - temperature radiator 1 and the condenser 2 more coordinated and consistent in the width direction, improving the neatness of the overall structure. Moreover, it is simple and convenient to manufacture. And since their left - right widths are the same, the air flow distribution passing through them can be more uniform, reducing local hot spots. And the unified width can reduce the flow resistance of the air when passing through the medium - temperature radiator 1 and the condenser 2, thereby reducing energy consumption, improving their cooling efficiency, and ensuring that the medium - temperature radiator 1 and the condenser 2 can be successfully installed in the preset installation space.

[0059] In some other embodiments, the ratio of the up - down height of the condenser 2 to the up - down height of the medium - temperature radiator 1 is 1.2 - 1.5. For example, the ratio can be 1.2, 1.3, 1.5, etc. Among them, high - temperature and high - pressure refrigerant flows in the condenser 2, which requires a larger surface area for cooling, while the medium - temperature radiator 1 may require a smaller surface area. By setting the above - mentioned values, the condenser 2 and the medium - temperature radiator 1 can partially overlap in height. Part of the air passes through the medium - temperature radiator 1 and then enters the condenser 2, and part of the air directly enters the condenser 2. This can increase the amount of air entering the condenser 2 and improve the heat - dissipation efficiency of the condenser 2. And by adjusting the height ratio, the heat - dissipation efficiency of both can be optimized.

[0060] Therefore, if the left - right width of the condenser 2 is the same as that of the medium - temperature radiator 1, only by adjusting the up - down height of the condenser 2 and the up - down height of the medium - temperature radiator 1, the heat dissipation of both can be adjusted, and it can adapt to the size of the installation space, and the structure is simple and convenient for manufacturing.

[0061] In some embodiments, the medium - temperature radiator 1 is provided with a front ventilation hole 12 that penetrates in the front - rear direction, and the condenser 2 is provided with a middle ventilation hole 22 that penetrates in the front - rear direction. The front ventilation hole 12 and the middle ventilation hole 22 are directly opposite and penetrate in the front - rear direction.

[0062] Specifically, such as Figure 4 and Figure 5As shown in the figure, the medium-temperature radiator 1 is provided with a radiator tube belt 13. The radiator tube belt 13 extends in the left-right direction, and there are multiple radiator tube belts 13. The multiple radiator tube belts 13 are evenly spaced along the vertical direction of the medium-temperature radiator 1. An anterior ventilation hole 12 is formed between two adjacent radiator tube belts 13 for the flow of gas, and the anterior ventilation hole 12 penetrates in the front-back direction. The condenser 2 has a similar structure to the medium-temperature radiator 1, and it is also internally provided with multiple radiator tube belts 13. The multiple radiator tube belts 13 are evenly spaced along the vertical direction of the condenser 2. A middle ventilation hole 22 is formed between two adjacent radiator tube belts 13, and the middle ventilation hole 22 penetrates in the front-back direction. The anterior ventilation hole 12 and the middle ventilation hole 22 are directly opposite and penetrate in the front-back direction, and the multiple anterior ventilation holes 12 and the multiple middle ventilation holes 22 penetrate in one-to-one correspondence, so that multiple airflow paths spaced along the vertical direction can be formed.

[0063] Thus, the directly opposite and penetrating ventilation holes help to form a direct airflow path, reduce the resistance of air flow, enable the cold air to flow through the medium-temperature radiator 1 and the condenser 2 more directly and smoothly, can reduce the possible local hot spots on the surfaces of the condenser 2 and the medium-temperature radiator 1, and ensure that the temperature distributions of the two are more uniform, respectively improving the heat dissipation effects of the two.

[0064] In some embodiments, the condenser 2 is provided with a middle ventilation hole 22 penetrating in the front-back direction, and the high-temperature radiator 3 is provided with a posterior ventilation hole 31 penetrating in the front-back direction. The middle ventilation hole 22 and the posterior ventilation hole 31 are directly opposite and penetrate in the front-back direction.

[0065] Specifically, as Figure 6 shown, the high-temperature radiator 3 is internally provided with multiple radiator tube belts 13. The multiple radiator tube belts 13 are evenly spaced along the vertical direction of the high-temperature radiator 3. A posterior ventilation hole 31 is formed between two adjacent radiator tube belts 13 for the flow of gas, and the posterior ventilation hole 31 penetrates in the front-back direction. The posterior ventilation hole 31 and the middle ventilation hole 22 are directly opposite and penetrate in the front-back direction, and the multiple middle ventilation holes 22 and the multiple posterior ventilation holes 31 penetrate in one-to-one correspondence, so that multiple airflow paths spaced along the vertical direction can be formed.

[0066] Thus, the directly opposite and penetrating ventilation holes help to form a direct airflow path, reduce the resistance of air flow, enable the cold air to flow through the condenser 2 and the high-temperature radiator 3 more directly and smoothly, can reduce the possible local hot spots on the surfaces of the condenser 2 and the high-temperature radiator 3, and ensure that the temperature distributions of the two are more uniform, respectively improving the heat dissipation effects of the two.

[0067] Among them, when the multiple front ventilation holes 12 of the medium-temperature radiator 1, the multiple middle ventilation holes 22 of the condenser 2, and the multiple rear ventilation holes 31 of the high-temperature radiator 3 are not aligned and penetrated in sequence, it is necessary to adjust the structures of the three to ensure that there are more penetrated ventilation holes to improve their respective heat dissipation efficiencies.

[0068] In some embodiments, the high-temperature radiator 3 is formed with a connecting structure 32 extending forward, and the medium-temperature radiator 1 and the condenser 2 are respectively connected to the connecting structure 32 to be relatively fixed to the high-temperature radiator 3.

[0069] Specifically, the connecting structure 32 is used to connect the medium-temperature radiator 1, the condenser 2, and the high-temperature radiator 3. The connecting structure 32 can be connected to the medium-temperature radiator 1 and the condenser 2 simultaneously, or can be separately connected to the medium-temperature radiator 1 and the condenser 2. As Figure 1 and Figure 2 shown, the connecting structure 32 is arranged on the side of the high-temperature radiator 3 and extends forward. The connecting structure 32 can be integrally formed with the high-temperature radiator 3, and can also be detachably connected to the high-temperature radiator 3, which is convenient for replacement and installation. In actual design, if the connecting structure 32 is configured as a connecting frame, the medium-temperature radiator 1 and the condenser 2 can be respectively connected to the connecting frame through fasteners such as bolts, or can also be connected by means of clamping, plugging, etc. Its connection method is simple, convenient for disassembly and assembly, and easy to maintain. Moreover, the connecting structure 32 can also be configured as other types of connecting plates, and the setting methods are diverse and can be flexibly selected.

[0070] Among them, the connecting structure 32 can be configured into multiple ones, and the multiple connecting structures 32 are spaced apart and distributed on the outer periphery of the high-temperature radiator 3, so that the high-temperature radiator 3 can be connected to the medium-temperature radiator 1 and the condenser 2 through the multiple connecting structures 32, which can improve the connection strength between the three, and can ensure the stability and reliability of the operation of the radiator assembly 100 when the vehicle is running.

[0071] In addition, the connecting structure 32 can be arranged on the medium-temperature radiator 1 or the condenser 2 to connect the high-temperature radiator 3 with the condenser 2 and the medium-temperature radiator 1. Its setting methods are diverse and can be selected according to actual space requirements and design requirements.

[0072] In some embodiments, the radiator assembly 100 further includes a cooling fan, and the cooling fan is installed in the front engine compartment. The cooling fan is located at the rear side of the high-temperature radiator 3 and at least partially distributed opposite to the high-temperature radiator 3 in the front-rear direction.

[0073] Specifically, the radiator assembly 100 is disposed in the installation space at the front end of the vehicle. The radiator assembly 100 can exchange heat with the internal structure of the vehicle, thereby ensuring the operational reliability of the vehicle. Moreover, the radiator assembly 100 is also provided with a cooling fan. The cooling fan is detachably connected in the front engine compartment, and the cooling fan is located at the rear side of the high-temperature radiator 3 and at least partially distributed opposite to the high-temperature radiator 3 in the front-rear direction. That is, when the cooling fan operates, it can drive the air flow around the high-temperature radiator 3, thereby cooling the high-temperature radiator 3. And when the cooling fan operates, the air in the installation space can all flow, enabling the medium-temperature radiator 1 and the condenser 2 to also be cooled, ensuring the operational reliability of the components in the front engine compartment. Among them, the cooling fan can be provided as one or more.

[0074] The present utility model also proposes a thermal management system.

[0075] The thermal management system according to an embodiment of the present utility model includes an electric drive heat exchange circuit, an air-conditioning circuit, an engine heat exchange circuit, and the radiator assembly 100 of any one of the above embodiments. The medium-temperature radiator 1 is selectively connected to the electric drive heat exchange circuit and / or the battery circuit and is used to cool the coolant in the electric drive heat exchange circuit and / or the battery circuit. That is, when the coolant in the electric drive heat exchange circuit needs heat exchange, the medium-temperature radiator 1 can be connected to the electric drive heat exchange circuit. In this way, the coolant flows into the medium-temperature radiator 1 and exchanges heat with the coolant through cold air, realizing the cooling of the coolant. When the heat of the coolant in the electric drive heat exchange circuit is relatively low, the medium-temperature radiator 1 can be disconnected from the electric drive heat exchange circuit, and there is no need to cool the coolant in the electric drive heat exchange circuit through the medium-temperature radiator 1. And when the coolant in the battery circuit needs heat exchange, the medium-temperature radiator 1 can be connected to the battery circuit, and the medium-temperature radiator 1 is used to cool the coolant in the battery circuit. In this way, the usage frequency of the medium-temperature radiator 1 can be saved, and the service life of the medium-temperature radiator 1 can be extended.

[0076] And the condenser 2 is connected to the air-conditioning circuit and is used to cool the refrigerant in the air-conditioning circuit. The air-conditioning circuit is also provided with a compressor and an evaporator. That is, when the air conditioner needs to be used, the compressor, the condenser 2, and the evaporator are all in working states. In this way, the refrigerant in the air-conditioning circuit flows into the condenser 2 and exchanges heat with the refrigerant through the cold air driven by the cooling fan, realizing the cooling of the refrigerant and the refrigeration of the air conditioner. When the air conditioner is not in use, the condenser 2 and the various structures of the air-conditioning circuit do not work, that is, there is no need for the condenser 2 to cool the refrigerant, the usage frequency of the condenser 2 can be saved, and the service life of the condenser 2 can be extended.

[0077] In addition, the high-temperature radiator 3 is selectively connected to the engine heat exchange circuit and is used to cool the coolant in the engine heat exchange circuit. That is, when the coolant in the engine heat exchange circuit needs heat exchange, the high-temperature radiator 3 can be connected to the engine heat exchange circuit. In this way, the coolant flows into the high-temperature radiator 3, and the cooling air is driven by the cooling fan to exchange heat with the coolant, realizing the cooling of the coolant. When the heat of the coolant in the engine heat exchange circuit is relatively low, the high-temperature radiator 3 can be disconnected from the engine heat exchange circuit, and there is no need to cool the coolant in the engine heat exchange circuit through the high-temperature radiator 3, which can save the usage frequency of the high-temperature radiator 3 and extend the service life of the high-temperature radiator 3.

[0078] Thus, according to different usage requirements and different states of vehicle operation, the different working states of the medium-temperature radiator 1, the condenser 2, and the high-temperature radiator 3 can be switched to meet different heat exchange requirements. Through the flexible adjustment of each circuit of the thermal management system, the reliability of each structure under different working conditions can be ensured.

The radiator assembly 100 includes a medium-temperature radiator 1, a condenser 2, and a high-temperature radiator 3. Among them, by setting the area of the front windward surface 21 of the condenser to be larger than the area of the front windward surface 11 of the medium-temperature radiator, the heat dissipation efficiency of the medium-temperature radiator 1 and the condenser 2 can be respectively improved, thereby enhancing the working heat dissipation capacity of the motor, battery, and engine, as well as the refrigeration capacity of the air conditioner, improving the working performance of the radiator assembly 100, and thus ensuring the safe and efficient operation of the vehicle under different working conditions.
