[0038] The following reference Figures 1-6Describe a radiator assembly 100 according to an embodiment of the present invention. The radiator assembly 100 can realize the detachable installation of a medium-temperature radiator 3 and a condenser 2 on a high-temperature radiator 1, which is flexible and convenient, improves the assembly convenience, ensures the accuracy of the installation positions of the medium-temperature radiator 3 and the condenser 2, and reduces the number of internal parts of the vehicle.

[0039] As Figures 1-6 shown, the radiator assembly 100 according to an embodiment of the present invention includes: a medium-temperature radiator 3, a condenser 2, and a high-temperature radiator 1.

[0040] The medium-temperature radiator 3 is used to communicate with an electric drive heat exchange circuit and / or a battery circuit, the condenser 2 is used to communicate with an air-conditioning circuit, the high-temperature radiator 1 is used to communicate with an engine heat exchange circuit, the medium-temperature radiator 3 is located at the front grille of the vehicle, and the condenser 2 and the high-temperature radiator 1 are sequentially installed behind the medium-temperature radiator 3 in the front-rear direction. Among them, the high-temperature radiator 1 is adapted to be connected to the vehicle body.

[0041] Among them, the radiator assembly 100 is arranged in the installation space at the front end of the vehicle and around the engine to dissipate heat and cool the engine, etc., to ensure the reliable operation of the engine. And the radiator assembly 100 can also be connected to the electric drive heat exchange circuit, the air-conditioning circuit, and the battery circuit, etc. inside the vehicle to dissipate heat and cool the internal parts of the vehicle, etc., and can also refrigerate the interior of the vehicle, etc., to ensure the reliable operation of the vehicle while reducing the energy consumption of the vehicle, improving the environmental protection and the use comfort.

[0042] Specifically, the radiator assembly 100 is provided with a high-temperature radiator 1. The high-temperature radiator 1 can be connected to the engine heat exchange circuit, and the high-temperature radiator 1 can be selectively communicated with the engine heat exchange circuit. When the engine operates, the internal parts do work and generate high temperature, and an engine heat exchange circuit is formed in the engine. A medium is provided in the engine heat exchange circuit. When the medium flows to the engine, heat exchange can be carried out to cool the engine, thereby ensuring the reliable operation of the engine. And the medium can flow through the engine heat exchange circuit to the high-temperature radiator 1, so that the medium can be heat-exchanged and cooled through the high-temperature radiator 1, and the cooled medium can also flow to the engine to cool the engine again to ensure the reliable operation of the engine. The medium can be set as coolant, etc.

[0043] Furthermore, the radiator assembly 100 is also provided with an intermediate-temperature radiator 3 and a condenser 2. The intermediate-temperature radiator 3 is installed at the vehicle front grille. The intermediate-temperature radiator 3 can be selectively connected to the electric drive heat exchange circuit and / or the battery circuit, that is, the intermediate-temperature radiator 3 can be only connected to the electric drive heat exchange circuit, or only connected to the battery circuit, or can be respectively connected to both the electric drive heat exchange circuit and the battery circuit to exchange heat and cool the coolant in the electric drive heat exchange circuit and / or the battery circuit, ensuring the reliability of the operation of the electric drive and / or the battery. The medium can be set as coolant, etc. When the vehicle is running, the air flow passing through the front grille can air-cool the intermediate-temperature radiator 3 to ensure the reliability of the operation of the intermediate-temperature radiator 3.

[0044] In addition, the condenser 2 can be connected to the air-conditioning circuit, and there is also a medium in the air-conditioning circuit. When the medium flows through the air-conditioning circuit, it can absorb heat, thereby cooling the passenger compartment. When the medium flows through the condenser 2, it can release heat, so that the medium can continue to absorb heat when flowing back to the air-conditioning circuit, ensuring the comfort of passengers. The medium can be set as refrigerant, etc.

[0045] Among them, the condenser 2, the high-temperature radiator 1 and the intermediate-temperature radiator 3 are all installed in the installation space at the front end of the vehicle. The intermediate-temperature radiator 3 is located at the front side in the installation space, the high-temperature radiator 1 is located at the rear side in the installation space, and the condenser 2 is located between the intermediate-temperature radiator 3 and the high-temperature radiator 1, that is, the condenser 2 and the high-temperature radiator 1 are installed in sequence behind the intermediate-temperature radiator 3 along the front-rear direction, which can improve the compactness of the components in the installation space. And setting the intermediate-temperature radiator 3 at the frontmost side makes the area for cold air to enter the intermediate-temperature radiator 3 larger, with better heat dissipation effect and higher heat dissipation efficiency. Setting the condenser 2 in the middle can improve the refrigeration capacity of the air conditioner, improve the use comfort, and can avoid the poor heat dissipation effect of the intermediate-temperature radiator 3 caused by the high outlet air temperature of the condenser 2, thereby ensuring the heat dissipation effect of the intermediate-temperature radiator 3.

[0046] In addition, the high-temperature radiator 1 is responsible for transferring a large amount of heat to the external environment. By firmly connecting the high-temperature radiator 1 to the vehicle body, the weight of the high-temperature radiator 1 can be dispersed to the vehicle body, reducing its load, thereby enhancing the structural stability of the radiator assembly 100, and keeping the high-temperature radiator 1 in a stable position during use, improving its performance. At the same time, the heat can be transferred out through the vehicle body, enabling the high-temperature radiator 1 to effectively disperse the heat and improve the heat dissipation effect. In practice, the high-temperature radiator 1 can be connected to the vehicle body by bolts, snap connections, etc., which is flexible and convenient.

[0047] Further, the medium-temperature radiator 3 and the high-temperature radiator 1 are connected through the first connection structure 4, which can achieve a reliable connection between the medium-temperature radiator 3 and the high-temperature radiator 1. The condenser 2 and the high-temperature radiator 1 are connected through the second connection structure 5, which can achieve a reliable connection between the condenser 2 and the high-temperature radiator 1. Among them, the first connection structure 4 can be set on the medium-temperature radiator 3 or the high-temperature radiator 1. Similarly, the second connection structure 5 can also be set on the condenser 2 or the high-temperature radiator 1 to achieve the connection.

[0048] When installing the radiator assembly 100, the first connection structure 4 and the second connection structure 5 can also be used to position the medium-temperature radiator 3 and the condenser 2, so as to achieve accurate installation. In other words, the first connection structure 4 and the second connection structure 5 not only play a connecting role, but also can play a positioning role, reducing the positioning structure and thus reducing the number of parts. Among them, the medium-temperature radiator 3 is detachably connected to the high-temperature radiator 1 through the first connection structure 4, and the condenser 2 is detachably connected to the high-temperature radiator 1 through the second connection structure 5. Its detachable connection method facilitates the installation of the medium-temperature radiator 3 and the condenser 2 on the high-temperature radiator 1 and is convenient for disassembly. In this way, when the medium-temperature radiator 3 or the condenser 2 fails and needs to be replaced or repaired, the medium-temperature radiator 3 or the condenser 2 can be easily and separately removed from the high-temperature radiator 1, which is flexible and convenient, without disassembling the entire radiator assembly 100, thereby reducing the maintenance cost.

[0049] Thus, through the first connection structure 4 and the second connection structure 5, the connection and disassembly between the medium-temperature radiator 3, the condenser 2 and the high-temperature radiator 1 can be achieved, without other additional installation and disassembly tools, which is flexible and convenient, reduces the number of parts inside the vehicle, and further reduces the vehicle weight to improve the structural compactness and light weight of the vehicle, and can reduce the vehicle manufacturing cost and operation energy consumption.

[0050] According to the radiator assembly 100 of the embodiment of the present invention, a medium-temperature radiator 3, a condenser 2 and a high-temperature radiator 1 are provided, which can ensure the operation reliability of the vehicle. The medium-temperature radiator 3 is detachably connected to the high-temperature radiator 1 through the first connection structure 4, and the condenser 2 is detachably connected to the high-temperature radiator 1 through the second connection structure 5, realizing the detachable installation of the medium-temperature radiator 3 and the condenser 2 on the high-temperature radiator 1, without other additional installation and disassembly tools, which is flexible and convenient, improves the assembly convenience, ensures the accuracy of the installation positions of the medium-temperature radiator and the condenser 2, reduces the number of parts inside the vehicle, and further reduces the vehicle weight to improve the structural compactness and light weight of the vehicle, and can reduce the vehicle manufacturing cost and operation energy consumption.

[0051] In some embodiments, the first connection structure 4 includes a first clamping hole 41 and a first clamping buckle 42 that are in clamping fit. One of the first clamping hole 41 and the first clamping buckle 42 is provided on the high-temperature radiator 1 and the other is provided on the medium-temperature radiator 3.

[0052] That is to say, the shapes and sizes of the first clamping hole 41 and the first clamping buckle 42 are adapted to each other. Thus, a firm connection between the medium-temperature radiator 3 and the high-temperature radiator 1 can be achieved through the clamping fit between the first clamping hole 41 and the first clamping buckle 42. Moreover, the first clamping hole 41 can be provided on the high-temperature radiator 1 and the first clamping buckle 42 can be provided on the medium-temperature radiator 3, or the first clamping hole 41 can be provided on the medium-temperature radiator 3 and the first clamping buckle 42 can be provided on the high-temperature radiator 1.

[0053] And / or, the second connection structure 5 includes a second clamping hole 51 and a second clamping buckle 52 that are in clamping fit. One of the second clamping hole 51 and the second clamping buckle 52 is provided on the high-temperature radiator 1 and the other is provided on the condenser 2.

[0054] That is to say, the shapes and sizes of the second clamping hole 51 and the second clamping buckle 52 are adapted to each other. Thus, a firm connection between the condenser 2 and the high-temperature radiator 1 can be achieved through the clamping fit between the second clamping hole 51 and the second clamping buckle 52. Moreover, the second clamping hole 51 can be provided on the high-temperature radiator 1 and the second clamping buckle 52 can be provided on the condenser 2, or the second clamping hole 51 can be provided on the condenser 2 and the first clamping buckle 42 can be provided on the high-temperature radiator 1.

[0055] Thus, the first connection structure 4 connected by clamping can achieve a firm connection between the medium-temperature radiator 3 and the high-temperature radiator 1, and the second connection structure 5 connected by clamping can achieve a firm connection between the condenser 2 and the high-temperature radiator 1. Moreover, the installation and disassembly are convenient, greatly improving the assembly efficiency and convenience. In addition, no other connecting parts are used, reducing the number of parts used and the space occupied, making the connection between the high-temperature radiator 1, the medium-temperature radiator 3 and the condenser 2 compact.

[0056] In some embodiments, as Figures 1-3 shown, the high-temperature radiator 1 is provided with a first connecting arm 11 extending forward. The first connecting arm 11 is used to connect the medium-temperature radiator 3 and the condenser 2. The first connecting arm 11 is adapted to extend to a position directly opposite to the medium-temperature radiator 3 in the left-right direction, and the first connecting arm 11 is adapted to extend to a position directly opposite to the condenser 2 in the left-right direction to accurately connect with the medium-temperature radiator 3 and the condenser 2.

[0057] One of the first engaging holes 41 and the first buckle 42 is provided on the first connecting arm 11. That is, the first engaging hole 41 can be provided on the first connecting arm 11, and the first buckle 42 can be provided on the radiator. Or, the first buckle 42 can be provided on the first connecting wall, and the first engaging hole 41 can be provided on the condenser 2 to realize the snap connection between the high-temperature radiator 1 and the medium-temperature radiator 3.

[0058] One of the second engaging holes 51 and the second buckle 52 is provided on the first connecting arm 11. That is, the second buckle 52 can be provided on the first connecting arm 11, and the second engaging hole 51 can be provided on the condenser 2. Or, the second engaging hole 51 can be provided on the first connecting arm 11, and the second buckle 52 can be provided on the condenser 2 to realize the snap connection between the high-temperature radiator 1 and the condenser 2.

[0059] Thus, by providing the first connecting arm 11 on the high-temperature radiator 1, the snap connection between the high-temperature radiator 1 and the condenser 2 and the medium-temperature radiator 3 is realized, and it is convenient to disassemble. Just separate the first buckle 42 and the second buckle 52 on the first connecting arm 11 from the first engaging hole 41 on the medium-temperature radiator 3 and the second engaging hole 51 on the condenser 2, or separate the first buckle 42 on the medium-temperature radiator 3 and the second buckle 52 on the condenser 2 from the first engaging hole 41 and the second engaging hole 51 on the first connecting arm 11, and the disassembly of the medium-temperature radiator 3 and the condenser 2 relative to the high-temperature radiator 1 can be realized. In practice, the first connecting arm 11 can be integrally formed with the high-temperature radiator 1 to improve the manufacturing convenience and the strength of the first connecting arm 11.

[0060] In some embodiments, the first connecting arm 11 is provided with the first engaging hole 41 and the second engaging hole 51, and the first engaging hole 41 and the second engaging hole 51 are spaced apart in a snap-fit manner, that is, the first engaging hole 41 and the second engaging hole 51 are spaced apart in a certain distance in the front-rear direction to correspond to the positions of the first buckle 42 and the second buckle 52, which is conducive to the snap-fit between the first engaging hole 41 and the first buckle 42 and the snap-fit between the second engaging hole 51 and the second buckle 52.

[0061] Among them, the medium-temperature radiator 3 is provided with the first buckle 42 on the outer side in the left-right direction to be snap-fitted with the first engaging hole 41 to realize the snap connection between the high-temperature radiator 1 and the medium-temperature radiator 3, and the condenser 2 is provided with the second buckle 52 on the outer side in the left-right direction to be snap-fitted with the second engaging hole 51 to realize the snap connection between the high-temperature radiator 1 and the condenser 2.

[0062] Specifically, as Figures 1-3 shown, the left and right sides of the high-temperature radiator 1 are provided with the first connecting arms 11 extending forward, that is, extending in the direction of the condenser 2 and the medium-temperature radiator 3. As Figure 2As shown in the figure, on the first connecting arm 11 on the left side, there are a first clamping hole 41 and a second clamping hole 51 spaced apart in the front-rear direction. The first clamping hole 41 is located on the front side of the second clamping hole 51, and the first clamping hole 41 and the second clamping hole 51 are open in the left-right direction, that is, open towards the direction of the first buckle 42 and the second buckle 52, which is conducive to the tight connection between them. Among them, as Figure 4 shown, on the outer side of the medium-temperature radiator 3 in the left-right direction, as shown on the left side in the figure, there is a first buckle 42 extending outward, as Figure 5 shown, on the outer side of the condenser 2 in the left-right direction, as shown on the left side in the figure, there is a second buckle 52 extending outward, and the installation heights of the first buckle 42 and the second buckle 52 are the same. In this way, when the first connecting arm 11 extends to a position directly opposite to the medium-temperature radiator 3 and the condenser 2 in the left-right direction, the first clamping hole 41 on the first connecting arm 11 corresponds to the position of the first buckle 42 and the first buckle 42 can extend into the first clamping hole 41 to be clamped and connected with the left side of the medium-temperature radiator 3. At the same time, the second clamping hole 51 on the first connecting arm 11 corresponds to the position of the second buckle 52 and the second buckle 52 can extend into the second clamping hole 51 to be clamped and connected with the left side of the condenser 2, so that the left sides of the medium-temperature radiator 3 and the condenser 2 are fixed simultaneously.

[0063] And on the first connecting arm 11 on the right side, there are a first buckle 42 and a second buckle 52 spaced apart in the front-rear direction. The first buckle 42 is located on the front side of the second buckle 52, and the first buckle 42 and the second buckle 52 extend forward, that is, extend towards the direction of the first clamping hole 41 and the second clamping hole 51, which is conducive to the tight connection between them. Among them, as Figure 4 shown, on the outer side of the medium-temperature radiator 3 in the left-right direction, as shown on the right side in the figure, there is a first clamping hole 41 open in the front-rear direction, as Figure 5 shown, on the outer side of the condenser 2 in the left-right direction, as shown on the right side in the figure, there is a second clamping hole 51 open in the front-rear direction, and the installation heights of the first clamping hole 41 and the second clamping hole 51 are the same. In this way, when the first connecting arm 11 extends to a position directly opposite to the medium-temperature radiator 3 and the condenser 2 in the left-right direction, the first buckle 42 on the first connecting arm 11 corresponds to the position of the first clamping hole 41 and the first buckle 42 can extend into the first clamping hole 41 to be clamped and connected with the right side of the medium-temperature radiator 3. At the same time, the second buckle 52 on the first connecting arm 11 corresponds to the position of the second clamping hole 51 and the second buckle 52 can extend into the second clamping hole 51 to be clamped and connected with the right side of the condenser 2, so that the right sides of the medium-temperature radiator 3 and the condenser 2 are fixed simultaneously.

[0064] Thus, two snap connections are achieved through the first connecting arm 11, that is, the high-temperature radiator 1 is stably and reliably connected to the medium-temperature radiator 3 and the condenser 2 simultaneously through the first connecting arm 11, which is simple and convenient and reduces the number of components.

[0065] In some embodiments, the high-temperature radiator 1 is provided with a second connecting arm 12 extending forward. The second connecting arm 12 is used to connect the medium-temperature radiator 3. The second connecting arm 12 is adapted to extend to a position directly opposite to the medium-temperature radiator 3 in the left-right direction to accurately connect with the medium-temperature radiator 3.

[0066] And one of the first snap holes 41 and the first snap buckle 42 is provided on the second connecting arm 12. That is, the first snap hole 41 can be provided on the second connecting arm 12 and the first snap buckle 42 can be provided on the medium-temperature radiator 3. Or, the first snap buckle 42 can be provided on the second connecting arm 12 and the first snap hole 41 can be provided on the medium-temperature radiator 3 to achieve the snap connection between the medium-temperature radiator 3 and the high-temperature radiator 1.

[0067] The high-temperature radiator 1 is provided with a third connecting arm 13 extending forward. The third connecting arm 13 is used to connect the condenser 2. The third connecting arm 13 is adapted to extend to a position directly opposite to the condenser 2 in the left-right direction to accurately connect with the condenser 2.

[0068] And one of the second snap holes 51 and the second snap buckle 52 is provided on the third connecting arm 13. That is, the second snap hole 51 can be provided on the third connecting arm 13 and the second snap buckle 52 can be provided on the condenser 2. Or, the second snap buckle 52 can be provided on the third connecting arm 13 and the second snap hole 51 can be provided on the condenser 2 to achieve the snap connection between the condenser 2 and the high-temperature radiator 1.

[0069] Thus, the connection between the high-temperature radiator 1 and the medium-temperature radiator 3 is achieved by providing the second connecting arm 12 on the high-temperature radiator 1, and the connection between the high-temperature radiator 1 and the condenser 2 is achieved by providing the third connecting arm 13 on the high-temperature radiator 1, which is convenient for disassembling and replacing the condenser 2 and the medium-temperature radiator 3. That is, when one of the condenser 2 or the medium-temperature radiator 3 is damaged or fails, only the condenser 2 or the medium-temperature radiator 3 needs to be disassembled separately through the second connecting arm 12 or the third connecting arm 13, greatly improving the convenience. In practice, the second connecting arm 12, the third connecting arm 13 and the high-temperature radiator 1 can be integrally formed to improve the manufacturing convenience and the strength of the second connecting arm 12 and the third connecting arm 13.

[0070] In some embodiments, the front end of the second connecting arm 12 is provided with the first snap hole 41, and the first snap buckle 42 is provided on the outer side of the medium-temperature radiator 3 in the left-right direction to be snap-fitted with the first snap hole 41. The front end of the third connecting arm 13 is provided with the second snap hole 51, and the second snap buckle 52 is provided on the outer side of the condenser 2 in the left-right direction to be snap-fitted with the second snap hole 51.

[0071] Specifically, as Figures 1-3 shown, the left and right sides of the high-temperature radiator 1 are provided with second connecting arms 12 and third connecting arms 13 extending forward, that is, both the second connecting arm 12 and the third connecting arm 13 extend towards the condenser 2 and the medium-temperature radiator 3. As shown in the left-right direction in the figure, a first buckle 42 is provided at the front end of the second connecting arm 12 on the right side, and a first clamping hole 41 is provided at the front end of the second connecting arm 12 on the left side. The first buckle 42 extends forward, and the first clamping hole 41 is open in the left-right direction to facilitate the connection of the second connecting arm 12 with the medium-temperature radiator 3. Among them, as Figure 4 shown, on the outer side of the medium-temperature radiator 3 in the left-right direction, a first clamping hole 41 that is open in the front-back direction is provided on the left side as shown in the figure, and a first buckle 42 that extends outward is provided on the right side. In this way, when the second connecting arm 12 extends to a position directly opposite to the medium-temperature radiator 3 in the left-right direction, the first buckle 42 on the second connecting arm 12 on the right side corresponds to the position of the first clamping hole 41 on the medium-temperature radiator 3 and the first buckle 42 extends into the first clamping hole 41 to be clamped and connected with the right side of the medium-temperature radiator 3, so that the right side of the medium-temperature radiator 3 is fixed. At the same time, the first clamping hole 41 on the second connecting arm 12 on the left side corresponds to the position of the first buckle 42 on the medium-temperature radiator 3 and the first buckle 42 extends into the first clamping hole 41 to be clamped and connected with the left side of the medium-temperature radiator 3, so that the left side of the medium-temperature radiator 3 is fixed, thereby fixing the left and right sides of the medium-temperature radiator 3 at the same time and improving the installation stability of the medium-temperature radiator 3.

[0072] Among them, the two sides of the medium-temperature radiator 3 and the left and right sides of the high-temperature radiator 1 are set to adopt different clamping and matching methods of the first buckle 42 and the first clamping hole 41 to realize the differential connection of the medium-temperature radiator 3 and the high-temperature radiator 1 on the left and right sides and realize asymmetric installation. Thus, when the radiator assembly 100 is subjected to an external force, the clamping and matching methods on both sides can present different clamping effects, realize the complementary locking force, avoid the simultaneous disconnection of the clamping and matching on both sides when the radiator assembly 100 is stressed, and improve the stability of the installation connection.

[0073] Similarly, as Figures 1-3 shown, a second buckle 52 is provided at the front end of the third connecting arm 13 on the right side, and a second clamping hole 51 is provided at the front end of the third connecting arm 13 on the left side. The second buckle 52 extends forward, and the second clamping hole 51 is open in the front-back direction to facilitate the connection of the third connecting arm 13 with the condenser 2. Among them, as Figure 5 shown, on the outer side of the condenser 2 in the left-right direction, a second clamping hole 51 that is open in the front-back direction is provided on the right side as shown in the figure. As Figure 1As shown in the figure, a drying tank 21 is provided on the right side of the condenser 2. In actual design, when the condenser 2 has a drying tank 21, the third connecting arm 13 extends to the drying tank 21 and is connected to it. When the condenser 2 does not have a drying tank 21, second buckles 52 extending outward can be provided on both sides of the condenser 2. In this way, when the third connecting arm 13 extends to a position directly opposite the condenser in the left-right direction, the second buckle 52 on the right-side third connecting arm 13 corresponds to the position of the second latching hole 51 on the condenser 2, and the second buckle 52 extends into the second latching hole 51 to be latched and connected to the condenser 2. The left-side third connecting arm 13 is connected to the drying tank 21 to fix the condenser 2.

[0074] Among them, both sides of the condenser 2 and the left and right sides of the high-temperature radiator 1 are set to adopt different latching and mating methods of the second buckle 52 and the second latching hole 51, so as to achieve a differential connection between the condenser 2 and the high-temperature radiator 1 on the left and right sides, and achieve an asymmetric installation. Thus, when the radiator assembly 100 is subjected to an external force, the latching and mating methods on both sides can present different latching effects, realizing complementary locking forces, avoiding the simultaneous disconnection of the latching and mating on both sides when the radiator assembly 100 is stressed, and improving the stability of the installation connection.

[0075] Among them, it should be noted that as Figure 3 shown, the first connecting arm 11 and the third connecting arm 13 above the left side of the high-temperature radiator 1 can be integrally arranged. In this way, the number of parts used and the occupied space can be further reduced, the integration degree and structural compactness of the radiator assembly 100 can be improved, and the manufacturing cost can be reduced. The installation is convenient. During installation, at one position, the first connecting arm 11 and the third connecting arm 12 are simultaneously connected to the medium-temperature radiator 3 and the condenser 2, that is, the condenser 2 can be doubly fixed, improving the fixing effect of the condenser 2. At the same time, with such a setting, the first connecting arm 11 and the third connecting arm 12 can strengthen and support each other, improving the structural stability, structural strength and the fixing effect on the medium-temperature radiator 3 and the condenser 2, and further making the radiator assembly 100 more reliable and stable.

[0076] In some embodiments, the medium-temperature radiator 3 and the condenser 2 are spaced apart.

[0077] Specifically, as Figure 6 shown, the medium-temperature radiator 3 and the condenser 2 are spaced apart by a certain distance in the front-back direction, and the medium-temperature radiator 3 is located in front of the condenser 2. Thus, interference between the medium-temperature radiator 3 and the condenser 2 can be avoided, enabling each to work efficiently, facilitating heat dissipation, and thus improving the heat dissipation effect.

[0078] In some embodiments, the first connection structure 4 is provided in multiple groups, that is, the first connection structure 4 can be set to two groups, three groups or even more groups. Providing multiple groups of the first connection structure 4 can provide multiple connection points, enabling the medium-temperature radiator 3 and the high-temperature radiator 1 to be connected through multiple first connection structures 4, thereby improving the connection stability and reliability between the medium-temperature radiator 3 and the high-temperature radiator 1.

[0079] Moreover, the multiple first connection structures 4 are spaced apart and distributed on the outer side of the medium-temperature radiator 3. For example, they can be distributed on the upper, lower, left and right outer sides. Thus, the first connection structures 4 can be evenly distributed on the outer side of the medium-temperature radiator 3, enabling the medium-temperature radiator 3 to be stably connected to the high-temperature radiator 1 and preventing uneven stress on the medium-temperature radiator 3.

[0080] In some embodiments, the second connection structure 5 is provided in multiple groups, that is, the second connection structure 5 can be set to two groups, three groups or even more groups. Providing multiple groups of the first connection structure 4 can provide multiple connection points, enabling the condenser 2 and the high-temperature radiator 1 to be connected through multiple second connection structures 5, thereby improving the connection stability and reliability between the condenser 2 and the high-temperature radiator 1.

[0081] Moreover, the multiple second connection structures 5 are spaced apart and distributed on the outer side of the condenser 2. For example, they can be distributed on the upper, lower, left and right outer sides. Thus, the second connection structures 5 can be evenly distributed on the outer side of the condenser 2, enabling the condenser 2 to be stably connected to the high-temperature radiator 1 and preventing uneven stress on the condenser 2.

[0082] In some embodiments, as Figure 4 shown, multiple groups of the first connection structures 4 are spaced apart and distributed on the left and right sides of the medium-temperature radiator 3. Thus, the first connection structures 4 can be evenly distributed on the left and right sides of the medium-temperature radiator 3, enabling the left and right sides of the medium-temperature radiator 3 to be stably connected to the high-temperature radiator 1 and preventing uneven stress on both sides of the medium-temperature radiator 3.

[0083] In some embodiments, as Figure 5 shown, multiple groups of the second connection structures 5 are spaced apart and distributed on the left and right sides of the condenser 2. Thus, the second connection structures 5 can be evenly distributed on the left and right sides of the condenser 2, enabling the left and right sides of the condenser 2 to be stably connected to the high-temperature radiator 1 and preventing uneven stress on both sides of the medium-temperature radiator 3.

[0084] In some embodiments, the high-temperature radiator 1 is provided with a mounting bracket 6. The mounting bracket 6 protrudes from the high-temperature radiator 1 and is used to connect to the vehicle body.

[0085] Specifically, the radiator assembly 100 is provided with a high-temperature radiator 1. The high-temperature radiator 1 can be connected to the vehicle body by bolts or the like, with simple installation, which can reduce the installation cost. Moreover, the high-temperature radiator 1 is provided with a mounting bracket 6. The mounting bracket 6 can be integrally formed with the high-temperature radiator 1 directly, or can be connected to the high-temperature radiator 1 by means such as welding. And the high-temperature radiator 1 can be connected to the vehicle body through the mounting bracket 6. The mounting bracket 6 protrudes from the high-temperature radiator 1, that is, the mounting bracket 6 can be set to protrude backward, which is convenient for the high-temperature radiator 1 to be connected to the vehicle body.

[0086] In practice, mounting brackets 6 can be provided on both the left and right sides of the high-temperature radiator 1, and the number of mounting brackets 6 on one side of the high-temperature radiator 1 can be set to at least one, that is, the number of mounting brackets 6 on one side of the high-temperature radiator 1 can be set to one, two, three, etc. The mounting bracket 6 can be connected to the vehicle body through connecting parts such as bolts, or can be connected to the vehicle body by snap connection. Furthermore, the high-temperature radiator 1 can be installed on the vehicle body, with convenient connection, and the setting of other components can be reduced, realizing the lightweight of the vehicle, and the installation cost can be reduced.

[0087] In some embodiments, the radiator assembly 100 further includes a cooling fan. The cooling fan is installed in the front engine compartment. The cooling fan is located behind the high-temperature radiator 1 and at least part of it is distributed directly opposite to the high-temperature radiator 1 in the front-rear direction.

[0088] Specifically, the radiator assembly 100 is arranged 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 running reliability of the vehicle. Moreover, the radiator assembly 100 is further provided with cooling fans. The number of cooling fans can be set to multiple. The cooling fans are located behind the high-temperature radiator 1 and at least part of them is distributed directly opposite to the high-temperature radiator 1 in the front-rear direction. That is, when the cooling fans operate, the air around the high-temperature radiator 1 can be driven to flow, and thus the high-temperature radiator 1 can be cooled. And when the cooling fans operate, the air in the installation space can all flow, so that the medium-temperature radiator 3 and the condenser 2 can also be cooled, ensuring the running reliability of the components in the front engine compartment.

[0089] Among them, it should be noted that the radiator assembly 100 further includes a wind deflector 7. The wind deflector 7 has a guiding effect on the air flow, such as Figure 6As shown in the figure, the air guide cover 7 is installed on the front side of the medium-temperature radiator 3, and the air guide cover 7 is located on the rear side of the front grille. The air guide cover 7 has an air inlet 71 and an air outlet 72 distributed in the front-rear direction. At least part of the inner top wall of the air outlet 72 is configured to be inclined upward from front to back and the upper end is connected to the top of the medium-temperature radiator 3. With such a setting, the air in the upper side area of the air guide cover 7 can be introduced into the medium-temperature radiator 3. At least part of the inner bottom wall of the air outlet 72 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 guide cover 7 can be introduced into the condenser 2. And through the above structural arrangement, the outer periphery of the air outlet can be connected to the radiator assembly 100, and the air guide cover 7 is hermetically connected to the radiator assembly 100, improving the reliability of the connection between the two. And when the air enters the air guide cover 7 from the air inlet 71 and enters the medium-temperature radiator 3 and the condenser 2 from the air outlet 72 of the air guide cover 7, the heat dissipation of the medium-temperature radiator 3 and the condenser 2 is realized.

[0090] Thus, by setting the air guide cover 7, the flow direction of the air can be controlled, so that more air is guided into the medium-temperature radiator 3 and the condenser 2 through the air guide cover 7, improving the utilization rate of the air.

[0091] The present utility model also proposes a thermal management system.

[0093] Specifically, the thermal management system is provided with an electric drive heat exchange circuit, an air-conditioning circuit, an engine heat exchange circuit, a battery circuit, and a radiator assembly 100.

And the coolant can flow to the high-temperature radiator 1 through the engine heat exchange circuit, so that the coolant can be cooled by heat exchange through the high-temperature radiator 1. And the cooled coolant can also flow to the engine to cool the engine again, ensuring the reliability of the engine operation.

[0094] Furthermore, the medium-temperature radiator 3 is disposed at the vehicle front grille. The medium-temperature radiator 3 can be selectively connected to the electric drive heat exchange circuit and / or the battery circuit. That is, the medium-temperature radiator 3 can be connected only to the electric drive heat exchange circuit, or only to the battery circuit, or can be connected to both the electric drive heat exchange circuit and the battery circuit respectively, so as to exchange heat and cool the coolant in the electric drive heat exchange circuit and / or the battery circuit, ensuring the reliability of the operation of the electric drive and / or the battery. Moreover, since the medium-temperature radiator 3 is located at the vehicle front grille, when the vehicle is running, the air flow passing through the front grille can cool the medium-temperature radiator 3 by air cooling, ensuring the reliability of the operation of the medium-temperature radiator 3.

[0095] In addition, the condenser 2 can be connected to the air-conditioning circuit, and there is refrigerant in the air-conditioning circuit. When the refrigerant flows through the air-conditioning circuit, it can absorb heat, thereby cooling the interior of the passenger compartment. When the refrigerant flows through the condenser 2, it can release heat, so that the refrigerant can continue to absorb heat when flowing back to the air-conditioning circuit, ensuring the comfort of passengers.

Without other additional installation and disassembly tools, it is flexible and convenient, improving the assembly convenience, ensuring the accuracy of the installation positions of the medium-temperature radiator 3 and the condenser 2, reducing the number of vehicle internal parts, and thus reducing the vehicle weight, so as to improve the vehicle structure compactness and light weight, and reducing the vehicle manufacturing cost and operation energy consumption.
