Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0032] The following is for reference. Figures 1-7 According to the embodiment of the present utility model, the heat dissipation module 1 is used to install the medium-temperature radiator 13 and the condenser 12 on the high-temperature radiator 11 by screwing. The high-temperature radiator 11 is directly assembled on the subframe 2 by plugging and clamping. This method solves the problem of time-consuming and labor-intensive assembly of heat dissipation by requiring tooling, and improves assembly efficiency.

[0033] like Figures 1-7 As shown, a heat dissipation module 1 according to an embodiment of the present invention includes: a high-temperature radiator 11, a condenser 12, and a medium-temperature radiator 13, wherein the condenser 12 and the medium-temperature radiator 13 are both connected to the high-temperature radiator 11; wherein the high-temperature radiator 11 has a first plug-in portion 522 at the bottom and a second plug-in portion 15 at the top, the first plug-in portion 522 is used to plug into and cooperate with the subframe 2, and the second plug-in portion 15 is used to plug into and cooperate with the vehicle body.

[0034] In practice, the heat dissipation module 1 is located at the front of the vehicle. The high-temperature radiator 11 of the heat dissipation module 1 can dissipate heat and cool down the engine to ensure the reliability of engine operation. The high-temperature radiator 11 can selectively connect to the heat exchange circuit of the engine. There is coolant in the heat exchange circuit of the engine. The coolant flows to the engine to cool it down. At the same time, the coolant can flow to the high-temperature radiator 11 to cool the coolant and thus cool the engine.

[0035] In addition, the heat dissipation module 1 also includes a medium-temperature radiator 13 and a condenser 12. The medium-temperature radiator 13 can selectively dissipate heat for components such as motors and electronic controls. The condenser 12 can be connected to the vehicle's air conditioning circuit. The main function of the condenser 12 is to dissipate heat for the air conditioning refrigerant, condensing the high-temperature and high-pressure gas into a medium-temperature and high-pressure liquid, and then throttling it through a throttling valve to become a low-temperature and low-pressure liquid, which is finally sent into the evaporator to absorb heat and evaporate.

[0036] In other words, in this embodiment of the utility model, the medium-temperature radiator 13 and the condenser 12 are first connected to the high-temperature radiator 11, so that the high-temperature radiator 11, the condenser 12 and the medium-temperature radiator 13 become a whole, thereby forming a heat dissipation module 1, and the high-temperature radiator 11 is connected to the subframe 2, that is, the entire heat dissipation module 1 is connected to the subframe 2.

[0037] In specific connection, the first insertion part 522 at the bottom of the high-temperature radiator 11 is inserted into the subframe 2, and the top of the high-temperature radiator 11 is provided with a second insertion part 15, which is inserted into the vehicle body. This improves the convenience of installation and eliminates the need for additional support fixtures in the prior art to assist in supporting the intermediate-temperature radiator 13, condenser 12, and high-temperature radiator 11 to connect the heat dissipation module 1 to the front of the subframe 2 by bolting. In the prior art, the bolt connection is inconvenient when no fixtures are used; however, this application directly inserts the high-temperature radiator 11 into the subframe 2, which is convenient to operate and eliminates the need for additional support fixtures, reducing assembly steps and time. Moreover, integrating the condenser 12 and intermediate-temperature radiator 13 into the high-temperature radiator 11 improves the integration of the heat dissipation module 1 and saves space.

[0038] In some embodiments, a liquid collection tank 14 is provided on the side of the high-temperature radiator 11, and a vibration damping buffer 5 is connected to the bottom of the liquid collection tank 14. The vibration damping buffer 5 includes a first buffer 51 and a second buffer 52 connected together. The first buffer 51 is constructed with a plurality of vibration damping cavities 512, and the bottom of the second buffer 52 is formed with a first insertion portion 522.

[0039] In practice, both sides of the high-temperature radiator 11 are provided with liquid collection tanks 14. One liquid collection tank 14 has an inlet 141 and the other liquid collection tank 14 has an outlet 142. The engine coolant can enter the high-temperature radiator 11 through the inlet 141, flow inside the high-temperature radiator 11, and flow out through the outlet 142, thereby entering the engine cooling flow path. A vibration damping buffer part 5 is connected to the lower part of the liquid collection tank 14, which improves the buffering performance at the connection between the high-temperature radiator 11 and the subframe 2. At the same time, connecting the vibration damping buffer part 5 to the lower part of the liquid collection tank 14 provides a reliable stress point for the connection of the vibration damping buffer part 5, improves the buffering performance of the vibration damping buffer part 5 on the liquid collection tank 14, and prevents the rigid connection between the subframe 2 and the high-temperature radiator 11 from damaging the liquid collection tank 14 and the high-temperature radiator 11 when the vehicle is subjected to vibration.

[0040] In some embodiments, the vibration damping buffer 5 is also detachably connected to the side of the condenser 12.

[0041] Specifically, refer to Figure 5 As shown, the bottom of the liquid collection tank 14 is formed with a bent fixing lug 513 facing the condenser 12. The side of the condenser 12 is provided with an extended fixing plate 122. The bent fixing lug 513 and the extended fixing plate 122 are connected by bolts. The bent fixing lug 513 and the vibration damping buffer part 5 are integrally formed, so that the vibration damping buffer part 5 can be connected to both the high-temperature radiator 11 and the condenser 12, thereby improving the stability of the vibration damping buffer part 5 and improving the buffering performance of the vibration damping buffer part 5 for both the high-temperature radiator 11 and the condenser 12.

[0042] In some embodiments, the rear side of the first buffer portion 51 is configured as a slope 511, and the upper end of the slope 511 is located in front of the lower end of the slope 511.

[0043] Reference Figure 2 and Figure 5 As shown, the first buffer part 51 can be constructed as a polygonal structure. The polygonal structure is integrated with the bent fixing ear 513. The bent fixing ear 513 is connected to the bottom of the liquid collection tank 14. The rear side of the polygonal structure is an inclined plane 511. By setting the rear side of the first buffer part 51 as an inclined plane 511, and the upper end of the inclined plane 511 is located in front of the lower end of the inclined plane 511, when the front of the vehicle is hit by a collision, the collision force of the front side can be applied to the first buffer part 51, and the force can be dispersed through the inclined plane 511 of the first buffer part 51. For example, the force of the horizontal collision can be dispersed to the direction perpendicular to the inclined plane 511 and the direction perpendicular to the vertical direction of the vehicle and downward, so as to avoid the force concentration and improve the collision resistance.

[0044] In some embodiments, refer to Figure 5As shown, the second buffer part 52 is constructed as a vibration damping pad. The vibration damping pad includes a vibration damping pad body 521 and a first insertion part 522 extending along the bottom of the vibration damping pad body 521. The first insertion part 522 is inserted into the subframe 2 and the vibration damping pad body 521 presses against the subframe 2.

[0045] Specifically, the damping pad body 521 is circular, while the first insertion part 522 is cylindrical and extends along the axial direction of the damping pad body 521. The diameter of the first insertion part 522 is smaller than the diameter of the damping pad body 521, so that after the first insertion part 522 is inserted into the subframe 2, the damping pad body 521 can press against the subframe 2, thereby improving the stability of the connection between the first insertion part 522 and the subframe 2.

[0046] Furthermore, the damping pad body 521 has a damping protrusion 5211 on the side facing the first buffer part 51. The damping protrusion 5211 and the first buffer part 51 can partially press against each other, thereby forming a buffer between the first buffer part 51 and the second buffer part 52. Thus, when subjected to an external force collision, the impact of the subframe 2 vibration on the heat dissipation module 1 is reduced. The bottom cross-sectional area of ​​the first buffer part 51 is larger than the area of ​​the damping pad body 521, thereby improving the stability of the first buffer part 51.

[0047] Among them, there are two vibration damping buffer parts 5, which are located at the lower ends of the high temperature radiator 11 and are respectively connected to the subframe 2, thereby improving the stability of the connection and the balance of force.

[0048] In some embodiments, the intermediate-temperature radiator 13, the condenser 12, and the high-temperature radiator 11 are distributed along the front-rear direction of the vehicle, and the intermediate-temperature radiator 13 and the high-temperature radiator 11 are detachably connected, as are the condenser 12 and the high-temperature radiator 11.

[0049] In other words, the condenser 12 and the high-temperature radiator 11 are installed sequentially behind the medium-temperature radiator 13 in a front-to-back direction. This improves the compactness of the structure. The medium-temperature radiator 13 needs to dissipate heat from many electronic control components, so placing it at the front allows for a larger area for cold air to enter, resulting in better heat dissipation and higher efficiency. Placing the condenser 12 in the middle improves the cooling capacity of the air conditioner and prevents the high temperature after heat exchange between the condenser 12 and the air conditioner refrigerant from causing poor heat dissipation in the medium-temperature radiator 13, thus ensuring its effective heat dissipation. The high-temperature radiator 11 is located at the rear, closer to the engine, which improves the ease of installation between the high-temperature radiator 11 and the engine.

[0050] Furthermore, in combination Figure 3 and Figure 4 As shown, Figure 3This is a schematic diagram showing the connection of the high-temperature radiator 11, condenser 12, and medium-temperature radiator 13 along one side of the vehicle's transverse direction. Figure 4 This is a schematic diagram showing the connection of the high-temperature radiator 11, condenser 12, and medium-temperature radiator 13 along the other side of the vehicle's transverse direction. The condenser 12 is provided with a first mounting part 121, the medium-temperature radiator 13 is provided with a third mounting part 131, and the high-temperature radiator 11 is provided with multiple second mounting parts 111. Some of the second mounting parts 111 and the first mounting parts 121 are connected by bolts to realize the connection between the condenser 12 and the high-temperature radiator 11. In addition, some of the second mounting parts 111 and the third mounting parts 131 of the medium-temperature radiator 13 are connected by bolts to realize the connection between the high-temperature radiator 11 and the medium-temperature radiator 13.

[0051] In other words, by connecting the medium-temperature radiator 13 to the high-temperature radiator 11 and the condenser 12 to the high-temperature radiator 11, the overall integrity of the heat dissipation module 1 is improved; therefore, by simply connecting the high-temperature radiator 11 to the subframe 2, the entire heat dissipation module 1 can be stably connected to the subframe 2.

[0052] Among them, the first mounting part 121, the second mounting part 111, and the third mounting part 131 are all connecting ears, and the connecting ears are provided with connecting holes. The bolts pass through the connecting holes of the two connecting ears to connect the corresponding two parts.

[0053] This utility model embodiment proposes a subframe assembly 100, including a subframe 2 and the aforementioned heat dissipation module 1. The subframe 2 includes a front crossbeam 21, and a suspension structure 3 is provided on the front side of the front crossbeam 21. A first insertion part 522 is inserted into the suspension structure 3.

[0054] Reference Figure 1 As shown, the heat dissipation module 1 is connected to the front side of the front crossbeam 21. The front side of the front crossbeam 21 is provided with a suspension structure 3, which is integrated with the front crossbeam 21. The first insertion part 522 at the bottom of the high-temperature radiator 11 is inserted into the suspension structure 3, thereby realizing the transition connection between the heat dissipation module 1 and the front crossbeam 21. This does not affect the strength of the front crossbeam 21 but also improves the strength of the front crossbeam 21, thereby improving the stability and impact resistance of the connection between the heat dissipation module 1 and the front crossbeam 21.

[0055] In some embodiments, refer to Figure 6 As shown, the suspension structure 3 includes a vertically extending part 31 and a horizontally mounting part 32 that are bent and connected. The vertically extending part 31 is connected to the front crossbeam 21. The horizontally mounting part 32 is bent toward the front side of the vertically extending part 31, and the horizontally mounting part 32 is provided with a first insertion hole 33. The first insertion part 522 is inserted into the first insertion hole 33.

[0056] In other words, the suspension structure 3 allows for a gap between the heat dissipation module 1 and the front crossbeam 21 of the subframe 2. The heat dissipation module 1 absorbs a significant amount of heat during vehicle operation. Without sufficient clearance, this heat could be conducted to the front subframe 2, causing it to expand and affecting its structural stability and function. Therefore, by setting the suspension structure 3, both the pre-installation of the high-temperature radiator 11 with the subframe 2 and the establishment of a gap between the heat dissipation module 1 and the subframe 2 can be achieved, preventing the heat generated during heat conduction from affecting the structural stability and function of the front subframe 2.

[0057] In some embodiments, continue to refer to Figure 6 As shown, the horizontal mounting part 32 has a hollow structure and is provided with an upper plate 321 and a lower plate 322. The first insertion hole 33 is provided on the upper plate 321. The upper plate 321 is provided with a first limiting part 331 extending toward the lower plate 322 at the first insertion hole 33. When the first insertion part 522 is inserted into the first insertion hole 33, the first limiting part 331 is squeezed against the outer periphery of the first insertion part 522.

[0058] In other words, when the first insertion part 522 is inserted into the first insertion hole 33, the first limiting part 331 limits the circumferential movement of the first insertion part 522, and the first limiting part 331 and the outer periphery of the first insertion part 522 are squeezed together, which improves the stability of the insertion between the bottom of the high temperature radiator 11 of the heat dissipation module 1 and the suspension structure 3, thereby improving the stability of the installation between the heat dissipation module 1 and the front crossbeam 21 of the subframe 2.

[0059] This utility model embodiment proposes a vehicle, including a radiator crossbeam 4 and the aforementioned subframe assembly 100, combined with... Figure 1 and Figure 7 As shown, the radiator beam 4 is located on top of the heat dissipation module 1. The radiator beam 4 is provided with a second insertion hole 42. The second insertion part 15 is adapted to be inserted into the second insertion hole 42 and is at least partially locked in the second insertion hole 42.

[0060] The radiator crossbeam 4 is a hollow structure and can be connected to the vehicle frame by welding or bolting. The radiator crossbeam 4 plays a crucial supporting and protective role in the vehicle, not only supporting and fixing the heat dissipation module 1 but also dispersing impact force in the event of a collision, protecting the safety of occupants and other important components. The top of the high-temperature radiator 11 is provided with a second insertion portion 15, which has a retaining ring 151 and a pressing portion 152 circumferentially arranged. The retaining ring 151 and the pressing portion 152 are spaced apart along the axial direction of the second insertion portion 15. The bottom wall 41 of the radiator crossbeam 4 is provided with a second insertion hole 42, and the bottom wall 41 has an upwardly extending... When the second insertion part 15 is inserted into the second insertion hole 42, the locking ring 151 of the second insertion part 15 is made of rubber. The locking ring 151 presses against the inner wall of the second limiting part 411 and after the second insertion part 15 passes through from bottom to top, the locking ring 151 is locked onto one side of the second limiting part 411, and the other side of the second limiting part 411 presses against the upper side of the bottom wall 41 of the radiator beam 4. At the same time, the pressing part 152 presses against the lower side of the bottom wall 41, thereby realizing the insertion between the second insertion part 15 and the radiator beam 4 and locking it into the second insertion hole 42, improving the convenience and stability of the connection between the heat dissipation module 1 and the radiator beam 4.
