[0002] With the increase in the power of tractors, the heat dissipation of the engine also increases, and the design standards of the tractor radiator system are also improving. To meet the heat dissipation requirements, the current tractor products arrange each heat dissipation component along the front-back direction of the tractor. For example, the intercooler is set as an independent unit in front of the water tank radiator, and the cooling air passes through each heat dissipation component in turn to improve the heat dissipation efficiency of the tractor. However, this also reduces the effective utilization rate of the overall space of the machine.

[0003] Therefore, it is necessary to provide a radiator assembly to overcome the defects existing in the above. Summary of the Utility Model

[0035] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the specific implementation manners of the present utility model will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other implementation manners can also be obtained.

[0036] Referring to the attached Figures 1 to 7 figures, this embodiment provides a radiator assembly, which is arranged on a tractor. The radiator assembly includes a front bracket 1, a water tank radiator 3, and an intercooler 4.

[0037] It should be noted that the water tank radiator 3 and the intercooler 4 in this embodiment are the core parts of the water tank radiator 3 and the intercooler 4. For those skilled in the art, the structures of accessories such as pipes and joints are not specifically described. The same applies to the condenser 6, the lifting radiator 7, and the chassis oil radiator 8 in the following text.

[0038] Referring to the attached Figure 1, the front bracket 1 is located in front of the tractor cab. A front hood 2 is provided on the front bracket 1. The front bracket 1 and the front hood 2 form an air duct, which has an air inlet side 13 and an air outlet side 14. The radiator 3 and the intercooler 4 are both located in the air duct. Specifically, the radiator 3 is installed on the front bracket 1, and its heat dissipation surface faces the air inlet side 13; the intercooler 4 is installed on the front bracket 1 and is arranged side by side with the radiator 3 along the horizontal (left - right) direction, and its heat dissipation surface faces the air inlet side 13.

[0039] On the one hand, the structure of the entire cooling assembly is compact, which can improve the space utilization rate of the whole machine. On the other hand, although this cooling assembly changes the two - layer cooling structure arranged along the front - rear direction into a single - layer cooling structure arranged side by side, although it sacrifices some heat dissipation areas of the radiator 3 and the intercooler 4, it reduces the air resistance of the entire cooling flow path, has a better heat dissipation effect, can maintain the original heat dissipation effect of the entire radiator assembly, and even has a better heat dissipation effect.

[0040] In order to integrate the radiator 3 and the intercooler 4 onto the front bracket 1 of the tractor, the radiator 3 and the intercooler are installed in the first frame 5. Two support brackets 11 are arranged in parallel along the front - rear direction on the front bracket 1 of the tractor. The lower part of the first frame 5 is fixedly installed on the two support brackets 11 by bolts and is vertically installed on the front bracket 1.

[0041] Refer to the appendix Figure 5 , the first frame 5 includes: a frame body 51 and a partition 52. The frame body 51 is a rectangular structure. The partition 52 is vertically arranged in the frame body 51 with respect to the front bracket 1 and divides the internal space of the frame body 51 into a first accommodation space 54 and a second accommodation space 55 along the horizontal (left - right) direction. Among them, the sizes between the first accommodation space 54 and the second accommodation space 55 need to ensure that the ratio of the heat dissipation area of the radiator 3 to the heat dissipation area of the intercooler 4 is 3 - 7, preferably 4.0 - 4.5, to ensure the basic heat dissipation effect of the radiator 3.

[0042] Since the heat dissipation of the radiator 3 and the intercooler 4 is inconsistent, therefore, cushion blocks 53 are provided on the upper and lower sides of the first accommodation space 54 and / or the second accommodation space 55, so that the first accommodation space 54 and the second accommodation space 55 are respectively abutted against the upper and lower parts of the radiator 3 and the intercooler 4, realizing the fixation of the radiator 3 and the intercooler 4 in the vertical direction and ensuring the installation stability of the radiator 3 and the intercooler 4.

[0043] Refer to the appendix Figure 6, the partition 52 includes a first member 521 and a second member 522 with a U-shaped cross-section, and the first member 521 and the second member 522 are symmetrically fitted to form a whole. On the one hand, the partition 52 can play a role in separating the space. On the other hand, during assembly, the user can adjust the degree of overlap between the first member 521 and the second member 522 so that the left and right sides of the first accommodation space 54 and the second accommodation space 55 are respectively abutted against the left and right parts of the radiator 3 and the intercooler 4, realizing the fixation of the radiator 3 and the intercooler 4 in the left and right directions.

[0044] In an additional embodiment, dust-proof screens are provided on the front and rear sides of the first frame 5 to prevent dust from entering and accumulating, which may affect the heat dissipation efficiency.

[0045] In an additional embodiment, a filling material 523 is provided between the first member 521 and the second member 522. The filling material 523 is a non-rigid material such as foam, which plays a supporting role and at the same time plays a heat insulation role to avoid heat exchange between the radiator 3 and the intercooler 4 and ensure the normal operation of the radiator 3 and the intercooler 4.

[0046] Refer to the appendix Figure 2 , the radiator assembly further includes: a condenser 6, a chassis oil radiator 8 and a lift radiator 7. The condenser 6 is installed on the front bracket 1, arranged in front of the radiator 3 and the intercooler 4, and its heat dissipation surface faces the air inlet side 13; the chassis oil radiator 8 is installed on the front bracket 1, arranged in front of the radiator 3 and the intercooler 4, and its heat dissipation surface faces the air inlet side 13; the lift radiator 7 is installed on the front bracket 1, arranged in front of the radiator 3 and the intercooler 4, and its heat dissipation surface faces the air inlet side 13.

[0047] It should be noted that the condenser 6, the lift radiator 7 and the chassis oil radiator 8 are not necessary radiators. The user can selectively configure them according to the usage requirements and the tractor control method, and there are other alternative embodiments. Of course, for those skilled in the art, other types of radiators can also be integrated, such as a radiator for the steering assist oil circuit.

[0048] In one embodiment, refer to the appendix Figure 4 , appendix Figure 7 , the condenser 6, the lift radiator 7 and the chassis oil radiator 8 are installed in the second frame 9 and arranged side by side along the vertical direction. Specifically, the second frame 9 is arranged on the front side of the first frame 5 and is separated from the first frame 5 by a predetermined distance; the second frame 9 includes a first mounting bracket 91 and a second mounting bracket 92, which are respectively installed on two support frames 11. The condenser 6 and the chassis oil radiator 8 are located in the same vertical plane and are fixedly installed between the first mounting bracket 91 and the second mounting bracket 92 by bolts.

[0049] In another embodiment, for example, a high-horsepower tractor has a relatively high heat dissipation requirement for the lifting radiator 7, and a radiator with a larger heat dissipation area is required. Therefore, the lifting radiator 7 can be installed on the first mounting bracket 91 and the second mounting bracket 92, and located in front of the condenser 6 and / or the chassis oil radiator 8, so as to improve the heat dissipation efficiency of the lifting radiator 7.

[0050] See attached Figure 4 In order to ensure the installation stability of the first frame 5 and the second frame 9, the middle and / or upper parts of the first frame 5 and the second frame 9 are connected by a support arm 12. One end of the support arm 12 is fixedly mounted on the first mounting bracket 91 and the second mounting bracket 92, and the other end of the support arm 12 is provided with a waist-shaped hole 121, which is mounted on both sides of the frame body 51 by screws.

[0051] In a preferred embodiment, the condenser 6 and / or the lifting radiator 7 and / or the chassis oil radiator 8 are microchannel radiators with a double-layer structure. The microchannel radiator not only has excellent heat dissipation performance and integration, but also can improve the heat dissipation effect of the entire radiator assembly. Moreover, the lifting radiator 7 and the chassis oil radiator 8 are integrated on the first frame 5, and the heat exchange oil circuits of the two on the microchannel radiator are independent oil circuits.

[0052] See attached Figure 6 The air guide cover 56 is arranged at the rear side of the first frame 5 and is fixedly installed on the frame. A fan (not shown in the figure) is arranged in the air guide cover 56. The fan is connected to the engine by transmission to guide the gas on the air inlet side 13 to pass through the second frame 9 and the first frame 5 in sequence to achieve heat dissipation for the air conditioning condenser 6, the chassis oil radiator 8, the lifting radiator 7, the water tank radiator 3 and the intercooler 4.

[0053] The test proves that, under the premise of ensuring that the overall size of the front bracket 1, the front hood 2, the air duct and each frame remains unchanged, the heat dissipation areas of the existing water tank radiator 3, the intercooler 4, the chassis oil radiator 8, the lifting radiator 7 and the condenser 6 are: 52.3m 3 、11.8m 3 、14.0m 3 、2.3m 3 、6.7m 3 In this embodiment, the heat dissipation areas of the water tank radiator 3, the intercooler 4, the chassis oil radiator 8, the lifting radiator 7 and the condenser 6 are: 46.9m 3 、11.6m 3 、16.9m 3 、3.9m 3 、7.2m 3 Although the heat dissipation areas of the water tank radiator 3 and the intercooler 4 are reduced, the heat dissipation areas of the chassis oil radiator 8, the lifting radiator 7 and the condenser 6 are increased.

[0054] In summary, in this embodiment, the water tank radiator 3 and the intercooler 4 are integrally arranged on the first frame 5, and the condenser 6, the lifting radiator 7 and the chassis oil radiator 8 are integrated in the second frame 9. On the one hand, the space utilization rate of the tractor is greatly improved. On the other hand, although part of the heat dissipation area of the water tank radiator 3 and the intercooler 4 is sacrificed, the original multi-layer heat dissipation structure is changed into a two-layer heat dissipation structure, reducing the wind resistance of the entire heat dissipation flow channel, and the air suction heat dissipation effect of the fan is better. It can not only maintain the original heat dissipation effect of the entire radiator assembly, but even has a better heat dissipation effect.

[0055] It will be apparent to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations of the present invention falling within the scope of the appended claims and their equivalent technical solutions.
