Description

Technical Field

[0001] This invention relates to the field of water tank radiator technology, specifically a truck water tank radiator with impact resistance. Background Technology

[0002] The radiator is a key component of the thermal management system of new energy vehicles. It is mainly used to cool components such as batteries, motors, and electronic control systems to ensure that they operate within the optimal temperature range. The batteries, motors, and electronic control systems of new energy vehicles generate a lot of heat when they are working. The main function of the radiator is to dissipate this heat, maintain the temperature of each component within a reasonable range, ensure their performance and safety, and extend their service life.

[0003] In existing technologies, the assembly gap between the cooling fins and the cooling water pipes of water tank radiators is too small during use, resulting in greater airflow resistance. This not only makes it difficult for the cooling fan to fully exert its cooling efficiency but also easily leads to uneven airflow, resulting in poor overall cooling performance. This may affect the heat exchange efficiency and circulation stability of the cooling medium. Furthermore, during truck operation, if the vehicle travels through bumpy roads or undergoes rapid acceleration or braking, the vehicle body will experience severe impact and shaking due to inertia, which will cause the water tank radiator to vibrate synchronously. Existing water tank radiators use rubber pad structures for cushioning protection, but the vibration and cushioning performance of rubber pads is insufficient, resulting in poor cushioning effect. Especially when the radiator is under heavy load or continuous bumpy conditions, the vibration and impact on the radiator cannot be effectively absorbed. Over time, this can easily lead to malfunctions such as weld cracking of the radiator body and loosening and leakage of cooling pipes, which may affect the normal operation of the water tank radiator. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a truck radiator with impact resistance to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a truck water tank radiator with impact resistance, comprising a radiator body, cooling water pipes, cooling fins, and a cooling fan. The radiator body has buffer assemblies at both ends, each buffer assembly including two sets of mounting blocks connected to the radiator body. Each mounting block has a semi-enclosed mounting frame on the side away from the radiator body. The radiator body has a transmission assembly inside, comprising multiple sets of guide plates rotatably connected inside the radiator body. These guide plates are located between the cooling fan and the cooling water pipes and cooling fins. Below the guide plates is a cleaning assembly for cleaning the cooling water pipes and cooling fins on the inner wall of the radiator body.

[0006] Preferably, multiple sets of second buffer rods are connected to both sides of the two sets of mounting blocks, and the other end of the second buffer rod is connected to the inner wall of the mounting frame. A first buffer rod is connected to the side surface of the two sets of mounting blocks away from the radiator body, and the end of the first buffer rod away from the mounting block is connected to the inner wall of the mounting frame.

[0007] Preferably, the inner walls of the first buffer rod and the second buffer rod are equipped with damping springs, the front and rear surfaces of the two sets of mounting blocks are equipped with first magnetic blocks located between multiple sets of second buffer rods, the side walls of the mounting blocks are equipped with first magnetic blocks at both ends of the first buffer rods, and the inner walls of the mounting frame are equipped with second magnetic blocks with the same magnetic poles as the first magnetic blocks at corresponding positions.

[0008] Preferably, a gear is fixedly sleeved on the outer wall of one end of the multiple sets of guide plates, and a vertically movable rod is provided on one side of the gear. Multiple sets of racks are fixedly connected to one side surface of the movable rod, and the racks mesh with the gears.

[0009] Preferably, a first cylinder is connected to the bottom end of the moving rod on the side away from the gear. The first cylinder is installed outside the radiator body, and a channel is opened on the side wall of the radiator body for the output end of the first cylinder to move.

[0010] Preferably, the inner walls of the first and second buffer rods are filled with oil, and the inner walls of the two sets of mounting blocks are provided with cavities, with the first and second buffer rods connected to the cavities. The bottom ends of the two sets of mounting blocks are connected to connecting pipes extending to the outside of the mounting blocks, and the two sets of connecting pipes are connected to each other and connected to the first cylinder.

[0011] Preferably, the cleaning component includes a mounting plate, with multiple sets of telescopic rods connected to one side surface of the mounting plate, and a connecting block connected to the lower surface of the guide plate, wherein the multiple sets of telescopic rods are fixedly connected to the connecting block.

[0012] Preferably, the mounting plate has two sets of guide grooves on the side surface away from the telescopic rod, and a cleaning brush is slidably connected to the inner wall of the guide groove. The cleaning brush is in contact with the cooling water pipe and heat dissipation fins on the inner wall of the radiator body.

[0013] Preferably, both ends of the cleaning brush are connected to a second cylinder, which is connected to the inner wall of the guide groove. The outer walls of the two sets of telescopic rods are connected to a fixing tube, the other end of which extends to the inner wall of the mounting plate and is connected to the second cylinder. The fixing tube is connected to the telescopic rod and the second cylinder.

[0014] Preferably, a return spring is sleeved on the outer wall of the multiple sets of telescopic rods, and the inner wall of the telescopic rods is filled with oil.

[0015] In summary, the present invention has the following main beneficial effects: 1. This invention uses a guide plate to direct and guide the airflow from the cooling fan, reducing airflow resistance at the gap between the cooling water pipes and the heat dissipation fins. This allows the airflow to smoothly penetrate the gap, maximizing the utilization of wind energy and improving efficiency. The guide plate, powered by the oil inside the first and second buffer rods, reciprocates, dynamically adjusting the airflow distribution. This ensures the airflow evenly covers the heat exchange area of ​​the cooling water pipes and heat dissipation fins, preventing localized airflow buildup or loss. This solves the problem of insufficient localized heat dissipation caused by uneven airflow, significantly improving the overall heat dissipation uniformity and efficiency of the radiator. In addition to improving thermal efficiency, the guide plate rotates in tandem with the cleaning brush, which, along with the return spring, ensures continuous contact between the cleaning brush and the cooling water pipes and heat dissipation fins. This facilitates the cleaning of dust and impurities on their surfaces. The cleaning brush can also reciprocate through the compression of the telescopic rod and the internal oil drive, improving the cleaning coverage and cleaning effect. This promptly removes accumulated dust and impurities from the surfaces of the cooling water pipes and heat dissipation fins, preventing dust from obstructing the heat exchange path and blocking the airflow channels. Maintaining the cleanliness of the heat exchange components ensures the long-term stability of the heat dissipation effect and further enhances the operational stability of the radiator body. 2. This invention utilizes the built-in damping springs in the first and second buffer rods to quickly absorb high-frequency, small-amplitude vibrations, achieving initial buffering and stress relief. This prevents direct vibration transmission and damage to the radiator body. Simultaneously, the first and second magnetic blocks with identical magnetic poles mounted on the mounting block and frame form a secondary buffer based on the principle of "like poles repel," further weakening the vibration impact. Furthermore, the buffer rods are filled with oil, which, due to the incompressibility and viscous damping properties of the liquid, further dissipates low-frequency, large-amplitude vibrations. This effectively avoids the rebound impact and incomplete buffering problems that often occur with damping springs. It also lubricates and protects the damping springs, reducing frictional loss during buffering and slowing down fatigue aging. It is also easy to adapt to left-right and front-back swaying, mitigating vibration impacts under heavy loads and bumpy conditions to a certain extent. This prevents radiator body weld cracking, pipe loosening and leakage, ensuring the structural integrity and operational reliability of the radiator body and extending its service life.

[0016] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structure, features, and effects of the present invention.

[0017] A truck radiator with impact resistance, such as Figure 1 - Figure 12 As shown, the radiator includes a radiator body 1, cooling water pipes, heat dissipation fins, and a heat dissipation fan. Buffer components are provided at both ends of the radiator body 1 to buffer and reduce vibration, thereby extending the service life of the radiator body 1 to a certain extent. The buffer components include two sets of mounting blocks 23 connected to the radiator body 1. Each mounting block 23 has a semi-enclosed mounting frame 21 on the side away from the radiator body 1. A transmission component is provided inside the radiator body 1. The transmission component includes multiple sets of guide plates 31 rotatably connected inside the radiator body 1. The guide plates 31 guide the airflow of the heat dissipation fan, improving the fan's energy utilization rate. The multiple guide plates 31 are located between the heat dissipation fan and the cooling water pipes and heat dissipation fins. A cleaning component is provided below the guide plates 31 to clean the cooling water pipes and heat dissipation fins on the inner wall of the radiator body 1.

[0018] See Figure 1 - Figure 6It is known that multiple sets of second buffer rods 24 are connected to both sides of the two sets of mounting blocks 23. The other end of the second buffer rod 24 is connected to the inner wall of the mounting frame 21. A first buffer rod 22 is connected to the side of the two sets of mounting blocks 23 away from the radiator body 1. The end of the first buffer rod 22 away from the mounting block 23 is connected to the inner wall of the mounting frame 21. When the radiator body 1 is subjected to impact or vibration, or when it is accelerated, decelerated, or braked suddenly, the first buffer rod 22 and the second buffer rod 24 connected to the mounting block 23 can be used to dampen the vibration of the radiator body 1, prevent damage to the radiator body 1, and extend the service life of the radiator body 1. Both the inner walls of the first buffer rod 22 and the second buffer rod 24 are equipped with damping springs. The installation of damping springs can provide initial buffering for the radiator body 1. The front and rear surfaces of the two sets of mounting blocks 23 are equipped with first magnetic blocks located between multiple sets of second buffer rods 24. The side walls of the mounting blocks 23 are equipped with first magnetic blocks at both ends of the first buffer rods 22. The inner wall of the mounting frame 21 is equipped with second magnetic blocks with the same magnetic poles as the first magnetic blocks at the corresponding positions. Through the magnetic principle of "like poles repel each other", the cooperation between the first magnetic blocks and the second magnetic blocks can further buffer the radiator body 1 and prevent vibration from being directly transmitted to the radiator body 1.

[0019] See Figure 3 - Figure 10 It is known that the inner walls of the first buffer rod 22 and the second buffer rod 24 are filled with oil. The inner walls of the two sets of mounting blocks 23 are provided with cavities, and the first buffer rod 22 and the second buffer rod 24 are connected to the cavities. The bottom ends of the two sets of mounting blocks 23 are connected to connecting pipes 25 extending to the outside of the mounting blocks 23. The two sets of connecting pipes 25 are connected to each other and connected to the first cylinder 36. When the radiator body 1 is vibrated, the buffer assembly performs a damping operation on the radiator body 1. When the first buffer rod 22 or the second buffer rod 24 is squeezed, the oil inside the first buffer rod 22 or the second buffer rod 24 will be pressurized and enter the first cylinder 36 through the connecting pipes 25, thereby pushing the output end of the first cylinder 36 to move vertically. When the buffer assembly continuously performs a damping operation on the radiator body 1, it can drive the output end of the first cylinder 36 to continuously reciprocate vertically. The bottom end of the moving rod 35 away from the gear 33 is connected to the first cylinder 36. The first cylinder 36 is installed outside the radiator body 1. The side wall of the radiator body 1 is provided with a channel for the output end of the first cylinder 36 to move. The first cylinder 36 can continuously reciprocate vertically under the action of oil, which facilitates the moving rod 35 to perform vertical reciprocating motion synchronously. A gear 33 is fixedly sleeved on the outer wall of one end of multiple sets of guide plates 31. A vertically movable rod 35 is provided on one side of the gear 33. Multiple sets of racks 34 are fixedly connected to one side surface of the movable rod 35. The racks 34 mesh with the gears 33. During the vertical reciprocating motion, the movable rod 35 synchronously drives the racks 34 to move. The racks 34 drive the meshing gears 33 to reciprocate synchronously. In turn, the gears 33 drive the guide plates 31 to swing back and forth. While the guide plates 31 sort the airflow, they can make the airflow evenly cover the heat exchange area of ​​the cooling water pipes and heat dissipation fins.

[0020] See Figure 8 - Figure 12 It is known that the cleaning component includes a mounting plate 42, a plurality of telescopic rods 44 are connected to one side surface of the mounting plate 42, a connecting block 32 is connected to the lower surface of the guide plate 31, and the plurality of telescopic rods 44 are fixedly connected to the connecting block 32. Two sets of guide grooves are provided on the side of the mounting plate 42 away from the telescopic rod 44, and a cleaning brush 41 is slidably connected to the inner wall of the guide groove. The guide groove can guide the movement direction of the cleaning brush 41. The cleaning brush 41 is in contact with the cooling water pipe and heat dissipation fins on the inner wall of the radiator body 1. Multiple sets of telescopic rods 44 are fitted with return springs on their outer walls, and the inner walls of the telescopic rods 44 are filled with oil. Through the return springs fitted on the outer walls of the telescopic rods 44, the cleaning brush 41 can be kept in continuous contact with the cooling water pipes and heat dissipation fins to clean the dust on their surfaces. The cleaning brush 41 is connected to a second cylinder 43 at both ends. The second cylinder 43 is connected to the inner wall of the guide groove. The outer walls of the two sets of telescopic rods 44 are connected to fixed pipes 45. The other end of the fixed pipe 45 extends to the inner wall of the mounting plate 42 and is connected to the second cylinder 43. The fixed pipe 45 is connected to the telescopic rods 44 and the second cylinder 43. When the guide plate 31 rotates back and forth, the cleaning brush 41 is continuously squeezed. Under the action of the return spring, the cleaning brush 41 is kept in contact with the cooling water pipe and the heat dissipation fins to clean their surfaces. At this time, the oil inside the telescopic rod 44 is pressurized and flows into the second cylinder 43 through the fixed pipe 45, thereby pushing the cleaning brush 41 to move back and forth in parallel during the rotation, improving the cleaning coverage and cleaning effect of the cleaning brush 41.

[0021] The working principle of this invention is as follows: When a truck is driving, it will shake when it passes through a bumpy road, is impacted, or performs operations such as acceleration / sudden braking. When the radiator body 1 is impacted or shaken, the first buffer rod 22 and the second buffer rod 24 can work together with two sets of first magnetic blocks and second magnetic blocks with the same magnetic poles to provide vibration damping protection for the radiator body 1. When the radiator body 1 sways left and right, the radiator body 1 shifts to one side, and the mounting block 23 exerts a squeezing effect on the first buffer rod 22. When the radiator body 1 wobbles back and forth, the mounting block 23 presses against the second buffer rod 24 to cushion the radiator body 1. Since both the first buffer rod 22 and the second buffer rod 24 are equipped with damping springs, they facilitate the initial damping of the radiator body 1. Since the surface of the mounting block 23 and the inner wall of the mounting frame 21 are equipped with a first magnetic block and a second magnetic block with the same magnetic poles, when the first magnetic block and the second magnetic block are close to each other, the magnetic principle of "like poles repel and unlike poles attract" can further dampen and reduce the vibration of the radiator body 1. At the same time, the damping springs can quickly bear the high-frequency small-amplitude vibrations transmitted by the radiator body 1, achieve initial damping and force relief, and prevent the vibration from being directly transmitted to the radiator body 1. Furthermore, both the first buffer rod 22 and the second buffer rod 24 are filled with oil. The oil, with its incompressibility and viscous damping properties, can effectively dissipate low-frequency large-amplitude vibrations, avoiding the rebound impact and incomplete buffering problems that occur during the buffering operation. In addition, the oil can play a lubricating and protective role, reducing the frictional loss of the damping spring during the buffering process, slowing down the fatigue aging rate of the damping spring, and at the same time, it can avoid the hidden danger of vibration damage to the radiator body 1 after buffering failure to a certain extent. During vehicle operation, the cooling fan cools the cooling water pipes and cooling fins on the radiator body 1. By adding a guide plate 31, the airflow sent out by the cooling fan can be sorted and guided, reducing the resistance loss at the gap between the cooling fins and the cooling water pipes, allowing the airflow to pass through the gap between the cooling fins and the cooling water pipes more smoothly, maximizing the use of existing wind energy and improving the wind energy utilization rate of the cooling fan. During vehicle operation, when the first buffer rod 22 and the second buffer rod 24 perform vibration damping operations, the oil inside them is squeezed into the cavity inside the mounting block 23. The oil is then squeezed into the first cylinder 36 through the connecting pipe 25 connected to the cavity. This, in turn, works with the first cylinder 36 to push the output end to drive the moving rod 35 to move vertically back and forth. During continuous vibration damping operations, the oil is continuously squeezed and drawn back, thereby achieving the reciprocating movement of the moving rod 35. When the moving rod 35 moves, it simultaneously drives multiple sets of racks 34 to move synchronously. When the racks 34 move, they drive the gears 33 that mesh with them to rotate, thereby driving the guide plate 31 to rotate back and forth. The reciprocatingly rotating guide plate 31 can dynamically and evenly adjust the airflow delivered by the cooling fan through continuous oscillation, so that the airflow can evenly cover the heat exchange area of ​​the cooling water pipe and the heat exchange fins, avoiding local airflow accumulation or lack, solving the problem of insufficient local heat dissipation caused by uneven airflow, and greatly improving the overall heat dissipation uniformity of the radiator body 1. During the reciprocating rotation of the guide plate 31, the cleaning brush 41 is driven to rotate synchronously through the connecting block 32. The cleaning brush 41 maintains close contact with the outer wall of the cooling water pipe and the surface of the heat dissipation fins, which facilitates the cleaning of the accumulated dust and impurities attached to the surface of the cooling water pipe and the heat dissipation fins, preventing dust from blocking the heat exchange path and affecting the cooling effect of the cooling fan on the cooling water pipe and the heat dissipation fins. During the rotation of the cleaning brush 41 driven by the guide plate 31, the return spring mounted on the outer wall of the telescopic rod 44 ensures that the cleaning brush 41 maintains continuous contact with the cooling water pipe and heat dissipation fins during its movement. Furthermore, the telescopic rod 44 is continuously compressed during the rotation of the cleaning brush 41. When the telescopic rod 44 is compressed, the oil inside it flows through the fixed pipe 45 into the second cylinder 43, pushing out the output end of the second cylinder 43. This pushes the cleaning brush 41 back and forth along the inner wall of the guide groove on the mounting plate 42, further improving the cleaning coverage and cleaning effect of the cleaning brush 41 and preventing dust accumulation from clogging the airflow channel.
