Description

Technical Field

[0001] The invention relates to the technical field of mechanical manufacturing, in particular to a radiator structure of a tractor. Background Art

[0002] With the rapid development of the market demand for medium-sized tugboats, tractors with more than 50 horsepower are equipped with air intake intercoolers to supercharge and cool the intake air. Although the emission and performance of the whole vehicle are optimized, the whole machine structure is compact and the assembly becomes more complicated.

[0003] However, in the existing radiator structure, two radiator bracket plates are used to position and install the radiators, which increases the gap between the radiators. The cold air is lost from both sides, resulting in a large cold air loss.

[0004] To address the above-mentioned drawbacks, in the prior art, Chinese Patent Publication No. CN220996113U discloses a tractor heat dissipation assembly, comprising two brackets, each mounted on either side of a water tank radiator. The water tank radiator is fixedly connected to an intercooler. An intercooler pipe is provided on the top of the intercooler. A chassis oil radiator and an air conditioning condenser are fixedly mounted in sequence on the side of the intercooler away from the water tank radiator. A fifth fixing plate is provided at the bottom of the water tank radiator, and a vertical sixth fixing plate is provided on the top of the water tank radiator. The sixth fixing plate has a through hole through which the intercooler pipe passes. The first, second, and fourth fixing plates are arranged vertically, and the fifth fixing plate is fixed to the tractor body. By arranging the brackets, the first, second, third, fourth, fifth, and sixth fixing plates, the air conditioning condenser, chassis oil radiator, intercooler, and water tank radiator are respectively and tightly fixed together in sequence, resulting in a compact structure and reducing the loss of cold air through gaps.

[0005] In the prior art, Chinese Patent Publication No. CN221049473U discloses a hybrid tractor radiator structure, comprising a bracket, with mounting seats fixedly connected to the front and rear sides of the upper end of the bracket, the upper end of the mounting seat fixedly connected to a connecting frame, and a first heat conduction mechanism disposed within the connecting frame; a connecting frame, a locking device comprising a connecting plate and a locking bolt, the connecting plate fixedly connected to the outer side of the connecting frame by bolts, and the locking bolt threadedly inserted into the front end of the connecting plate, the upper front end of the connecting frame connected to the frame via a rotating shaft, and a second heat conduction mechanism fixedly connected within the frame. Heat dissipation from the generator, motor, and battery pack is integrated with heat dissipation from the engine, utilizing the engine fan to dissipate heat, saving costs for electronic fans, simplifying piping and wiring layout, and achieving a compact structure. Because tractor operating conditions are relatively harsh and the air is often filled with debris, to facilitate radiator cleaning, the intercooler and water radiator are fixed together through the frame. When the second row of radiators is clogged with debris, the locking device can be loosened, and the first row of radiators can be rotated open about the rotating shaft, thereby facilitating debris cleaning.

[0006] The above-mentioned device uses a radiator to reduce the heat of the equipment during use, thereby ensuring stable operation of the equipment. However, due to the structural limitations of the overall device, the intercooler connection form and direction are different, resulting in an excessive number of parts. Workshop assembly workers are prone to confusing the pipes. Once the pipes are confused, the gap is too large or mismatched, which may cause the clamp after the turbocharger to burst.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solutions: a radiator structure for a tractor, comprising a supercharger body 1, an intercooler body 2 is provided on the outer surface of the supercharger body 1, an intercooler air inlet pipe 3 is provided on the outer surface of the intercooler body 2, the intercooler air inlet pipe 3 is used to reduce the engine intake temperature, an intercooler air outlet pipe 4 is provided on the outer surface of the intercooler body 2 away from the intercooler air inlet pipe 3, the intercooler air outlet pipe 4 is used to connect the supercharger body 1 and the intercooler body 2; a cavity 5 is provided on the inner side of the intercooler body 2, a fixed shell 6 is provided on the inner side of the intercooler body 2, a heat conduction mechanism is provided on the inner side of the fixed shell 6, and the heat conduction mechanism is used to enhance the heat dissipation capacity of the intercooler body 2; a protective shell 18 is provided on the end of the fixed shell 6 away from the mounting frame 8, a fixing seat 26 is provided on the outer surface of the protective shell 18, and a buffer mechanism for adaptively adjusting vibration is provided on the inner side of the fixing seat 26.

[0023] The heat conduction mechanism is provided to facilitate heat dissipation from the interior, thereby reducing the amount of heat generated. The intercooler outlet pipe 4 connects the supercharger body 1 and the intercooler body 2, thereby lowering the engine's intake air temperature. The intercooler intake pipe 3 is provided to lower the engine's intake air temperature, thereby improving engine performance and efficiency. (When exhaust gas from the engine passes through the supercharger body 1, it will bring significant heat, which will directly affect the temperature and air density of the intake air and reduce the air charging efficiency.) The intervention of the intercooler body 2 ensures that air can enter the engine more efficiently, promotes combustion, reduces fuel consumption and emissions, and improves vehicle power. Part numbers are marked on the surface of the parts used for assembly, making it easier for assembly workers to distinguish and identify them, effectively avoiding various problems caused by pipe confusion during the assembly process. This solution also changes the original connection and fixation method of the two rubber hoses at both ends and the metal tube in the middle to an integrated structure. Under the premise of meeting the key performance parameters such as the diesel engine's supercharging performance and the required strength and pressure, a single piece of silicone rubber (A05-2-A20-Or material) with an inner steel wire is used to make the intercooler connecting pipe. This improves the reliability and stability of the entire equipment and significantly reduces the probability of failure.

[0024] Example 2: Based on Example 1, please refer to Figure 2 - Figure 7 , also discloses a fixed shell 6, the specific structure of which is as follows: the heat conduction mechanism includes a heat sink 7, the heat sink 7 is provided with multiple groups, the multiple groups of heat sinks 7 are arranged at the inner end of the fixed shell 6, the outer surface of the fixed shell 6 is provided with a mounting frame 8, the inner side of the protective shell 18 is provided with a heat sink 19, the heat sink 19 is provided with multiple groups, the inner side of the protective shell 18 is provided with a heat dissipation hole 20, the protective shell 18 is provided with a fixing seat 26 at one end away from the fixed shell 6, the protective shell 18 increases the protection of the heat sink 19, the four corners of the mounting frame 8 are provided with screw holes, the screw holes of the mounting frame 8 are provided Screws 9 are provided, and the mounting frame 18 is connected to the fixed shell 6 through the screws 9. A shell 10 is provided at the end of the mounting frame 18 away from the fixed shell 6. A heat dissipation component 12 is provided on the inner side of the shell 10. The heat dissipation component 12 is used to increase the speed of air flow. A mounting frame 2 11 is provided on the outer surface of the shell 10. A protective cover 13 is provided on the outer surface of the mounting frame 2 11. A heat dissipation circulation pipe 14 is provided on the inner side of the fixed shell 6. A connecting pipe 15 is provided on the outer surface of the connecting pipe 15. A transmission pipe 16 is provided on the outer surface of the connecting pipe 15. The heat dissipation circulation pipe 14 is used to improve the heat dissipation efficiency.

[0025] The heat flowing into the intercooler body 2 is absorbed by the heat sink 7. Figure 3It can be seen that in order to avoid heat accumulation and a sharp rise in temperature, the absorbed heat is transferred to various parts of the heat sink 7, making full use of the large heat capacity and surface area. The heat is then dissipated into the air through various heat exchange paths on the surface. With the cooperation of the heat dissipation component 12 (the heat dissipation component 12 includes a micro motor for driving and a fan for reducing heat), forced convection is performed to increase the circulation speed of the internal air, thereby improving the heat dissipation effect. The mounting frame 8 and the fixed shell 6 are connected by the screws 9 provided. Figure 5 It can be seen that the cooperation between the shell 10 and the protective cover 13 reduces damage to the heat dissipation component 12, prevents large external impurities from entering the intercooler body 2 and causing damage to the heat dissipation component 12, and improves the stability of the equipment.

[0026] Example 3: Based on Example 1, please refer to Figure 5 - Figure 10 , also discloses fins 23, whose specific structure is as follows: the inner side of the transmission tube 16 is provided with a positioning member 17, the positioning member 17 has a positioning hole, the positioning member 17 is arranged on the inner side of the fixed shell 6, and the positioning member 17 is used to position the transmission tube 16, the protective shell 18 adopts a double-layer separation design, the outer surface of the protective shell 18 is provided with a U-shaped conduit 21, the outer surface of the U-shaped conduit 21 is provided with a delivery pipe 22, the delivery pipe 22 is provided with multiple groups, and the multiple groups of delivery pipes 22 are connected by the U-shaped conduit 21, and the inner side of the delivery pipe 22 is provided with fins 23, which are used to increase the heat dissipation area, The connecting end of the U-shaped guide tube 21 is provided with a connecting tube 24, the outer surface of the connecting tube 24 is provided with an arc tube 25, the outer surface of the arc tube 25 is provided with a fixed shell 6, the buffer mechanism includes an adjusting rod 27, the outer surface of the adjusting rod 27 is provided with a shock-absorbing damper 28, the outer surface of the shock-absorbing damper 28 is provided with a mounting seat 29, the inner side surface of the mounting seat 29 is provided with a movable rod 34, the outer surface of the movable rod 34 is provided with a positioning seat 30, the outer surface of the positioning seat 30 is provided with a connecting seat 31, the outer surface of the connecting seat 31 is provided with a connecting block 32, and the inner side surface of the connecting block 32 is provided with a driving rod 33.

[0027] The heat dissipation circulation pipe 14 is provided to circulate the circulating heat, thereby raising the temperature inside the cavity 5 (from the refrigerant to the heat medium, and then the heat medium to the refrigerant). The heat dissipation efficiency is improved through recycling. The hot gas is transmitted through the connecting pipe 15 and then discharged (or discharged) through the two sets of transmission pipes 16. The positioning members 17 are provided to achieve the positioning of the transmission pipes 16, thereby preventing the transmission pipes 16 from deflecting when vibrating, thereby increasing the stability of the equipment. By setting the bolt (by Figure 3 It can be seen that the middle part of the heat sink 7 located inside the fixed shell 6 is provided with a plurality of bolts) to fix the fixed shell 6 (by Figure 3It can be seen that the fixed shell 6 can be disassembled into an upper cover and a lower cover, which are connected to the protective shell 18 by screws 9. The heat sink 19 provided inside the protective shell 18 is used to improve the heat dissipation effect. The heat dissipation holes 20 are provided to increase the efficiency of heat flow, and the protective shell 18 adopts a double-layer separation design. A delivery pipe 22 is provided in the interlayer between the fixed shell 6 and the heat sink 19. The delivery pipe 22 is connected by a U-shaped conduit 21 to facilitate the circulation of the internal medium. The connecting pipe 24 connected to the U-shaped conduit 21 transmits the medium to the arc tube 25, and then the medium is transferred to the fixed shell 6 (the arc tube 25 adopts a ring design inside the fixed shell 6, and the other side of the connection is connected to the fixed shell 6). Figure 5 The water flows through the arc tube 25 and the connecting tube 24 in the U-shaped conduit 21 and then returns to the delivery pipe 22 installed in the protective shell 18. The extension of the connecting end of the U-shaped conduit 21 is used to connect to the circulating water pump (the circulating water pump is connected to the water tank), and the delivery pipe 22 is provided with fins 23 inside, which increases the water resistance and heat dissipation area, greatly improving the heat dissipation efficiency of the radiator, which is 3-5% higher than that of the traditional plate radiator. The various pipes are connected by a thickened main board, which replaces the seals of the traditional plate radiator, thereby improving work efficiency and reducing product costs. As a result, the performance of the entire tractor intercooling system has been significantly improved, labor costs and enterprise manufacturing costs have been effectively reduced, air flow efficiency has been improved, the power performance and work efficiency of the whole machine have been correspondingly enhanced, and the failure rate has been greatly reduced. It provides solid technical support for the efficient and reliable operation of the tractor and has good market application prospects and promotion value. The adjusting rod 27 is positioned by the set fixing seat 26, and the setting of the shock-absorbing damper 28 effectively absorbs the vibration generated by the operation of the equipment, reduces the loosening or damage of components caused by vibration, and further improves the stability and durability of the equipment. The cooperation between the mounting seat 29 and the movable rod 34 enables the entire heat dissipation structure to have good flexibility and adaptability while maintaining efficient heat dissipation. The precise design of the positioning seat 30, the connecting seat 31 and the connecting block 32 ensures a close connection between the components and avoids the decrease in heat dissipation efficiency due to loose connection. The introduction of the driving rod 33 provides a power source to drive the coordinated operation of the entire heat dissipation structure (reducing the amplitude of the heat dissipation structure), ensuring the efficiency and stability of the heat dissipation process. The precise cooperation and efficient operation of these components jointly construct a stable and efficient heat dissipation system, which provides a strong guarantee for the long-term and high-intensity operation of the tractor.
