Description

Technical Field

[0001] This utility model relates to the field of oil cooler technology, specifically a circulating air-cooled oil cooler. Background Technology

[0002] Air-cooled oil coolers are a type of cooler characterized by using air as the heat exchange medium. Heat is carried away by the air, hence the name air cooler. Current air-cooled oil coolers combine internal fluid and air channels, with the core constructed using vacuum brazing. Compared to traditional copper tube coolers, this significantly increases the heat exchange area per unit volume, making it 10-20 times larger and resulting in superior heat exchange efficiency. They are commonly used as auxiliary components in hydraulic transmission systems to cool hydraulic oil, ensuring it reaches its normal operating temperature range and improving the stability of the hydraulic system and the lifespan of its components.

[0003] According to a publicized circulating air-cooled oil cooler (publication number: CN220103811U), the above application sets a filter screen on the other side of the mounting cover so that the filter screen can intercept floating impurities in the air intake direction of the fan blades, so as to prevent impurities from being sucked into the mounting cover and eventually blown into the heat dissipation fin assembly, causing the problem of poor local ventilation and heat dissipation of the heat dissipation fin assembly. Secondly, the filter screen is fixedly connected to two conveyor belts, and a scraper is elastically set at the bottom of the mounting cover so that the filter screen can also remove and clean the floating impurities adsorbed on its surface by the drive of the conveyor belt and the scraping of the scraper.

[0004] However, in the aforementioned application, the dust and some debris adhering to the surface of the filter screen cannot be completely cleaned after long-term use, and its filtration effect will decrease after long-term use, blocking the passage of external air and requiring replacement. However, the replacement can only be carried out by stopping the operation of the entire equipment, which will affect the working efficiency of the air cooler. Utility Model Content

[0005] The purpose of this invention is to provide a circulating air-cooled oil cooler to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating air-cooled oil cooler, including a mounting cover, a base fixed to the bottom of the mounting cover, and a filter assembly and a linkage assembly disposed on the surface of the mounting cover and the base. The filter assembly includes: a fixed box, a sealing door, a concave frame, a filter plate, a partition, a Y-shaped tube, and a suction hood. The linkage assembly includes:

[0007] A fixed cylinder is fixed to the top of a fixed box, and its bottom is connected to the fixed box. A movable rod is piston-connected to the inner wall of the fixed cylinder. A base plate is fixed to the bottom of the movable rod, and a rubber plug is fixed to the top of the base plate. A stabilizing rod is fixed to the top of the movable rod, and its top penetrates the fixed cylinder and is slidably connected to it. A connecting plate is fixed to the top of the stabilizing rod, and a rack is fixed to the surface of the connecting plate. A stabilizing plate is fixed to the top of the fixed box, and a gear is rotatably connected to the surface of the stabilizing plate. The gear meshes with the rack. The linkage assembly also includes a limiting component. By rotating the gear with a rocker arm, the two sets of racks rotate in opposite directions. One set of rubber plugs blocks one set of air inlets of the Y-shaped tube, while the other set of rubber plugs no longer blocks the other air inlet of the Y-shaped tube. The other set of filter plates performs filtration. At this time, the sealing door corresponding to the filter plate that needs to be replaced is opened, and the filter plate can be pulled out for replacement.

[0008] Preferably, the limiting component includes a T-shaped plate, which is slidably connected to the surface of the stabilizing plate. A spring is fixed to the bottom of the T-shaped plate, and the bottom of the spring is fixed to the top of the fixing box. The T-shaped plate is located between the teeth of the gear to limit the gear.

[0009] Preferably, the surface of the fixed box is connected to a sealed door, the inner wall of the fixed box is fixed with a partition, the surface of the partition and the inner wall of the fixed box are both fixed with concave frames, the inner side of the concave frames is placed with a filter plate, the top of the fixed box is fixed with a Y-shaped tube, the Y-shaped tube is interconnected with the fixed box, the end of the Y-shaped tube away from the fixed box is fixed with a suction hood, the end of the suction hood away from the Y-shaped tube is fixed with a mounting cover, and the suction hood is interconnected with the mounting cover. When the heat exhaust fan is turned on, the air enters the fixed box through the air inlet of the fixed box, is filtered by the filter plate, and then enters the mounting cover through the Y-shaped tube and the suction hood.

[0010] Preferably, the mounting cover is equipped with a heat exhaust fan inside, and an oil supply pipe is fixed on the surface of the mounting cover. There are two sets of oil supply pipes, and the two sets of oil supply pipes are symmetrically arranged with the center line of the mounting cover as the axis of symmetry. A heat exchange tube bundle is connected between the two sets of oil supply pipes, and the heat exchange tube bundle is interconnected with the oil supply pipe. A heat dissipation fin assembly is connected between the heat exchange tube bundles. The air force passes through the heat dissipation fin assembly and dissipates heat from the heat dissipation fin assembly. The oil is injected from the interface of one set of oil supply pipes, and after being dispersed and dissipated by several heat exchange tube bundles, it converges into the other set of oil supply pipes and flows out from the top of the other set of oil supply pipes.

[0011] Preferably, the surface of the fixed box is provided with an air inlet hole, which allows outside air to enter.

[0012] Preferably, the concave frame, sealing door, and filter plate are provided in two sets, and the two sets of concave frames, sealing doors, and filter plates are symmetrically arranged with the center line of the fixed box as an axis of symmetry, so they can be used alternately, which is convenient for replacement without stopping the operation of the equipment.

[0015] Beneficial effects:

[0016] 1. This circulating air-cooled oil cooler, through a set linkage component, uses a rocker arm to rotate the gears, causing two sets of racks to rotate in opposite directions. One set of connecting plates, stabilizing rods, movable rods, base plates, and rubber plugs moves upward, while the other set moves downward. This causes one set of rubber plugs to block one set of air inlets of the Y-shaped tube, while the other set of rubber plugs no longer blocks the other air inlet of the Y-shaped tube. At this time, the other set of filter plates begins filtration. Simply open the sealing door corresponding to the filter plate that needs to be replaced, pull out the filter plate, and replace it without stopping the equipment. The set limiting component can limit the gears to prevent the gears from rotating during use or replacement of filter plates, which would affect the seal.

[0017] 2. This circulating air-cooled oil cooler, through the set filter components, turns on the heat exhaust fan, and the air enters the fixed box through the air inlet of the fixed box, is filtered by the filter plate, and then enters the mounting cover through the Y-shaped pipe and the air suction hood. Subsequently, the air passes through the heat dissipation fin assembly and dissipates heat from the heat dissipation fin assembly. Attached Figure Description

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a circulating air-cooled oil cooler, including a mounting cover 1, a base 5 fixed to the bottom of the mounting cover 1, and a filter assembly 7 and a linkage assembly 8 provided on the surface of the mounting cover 1 and the base 5. The filter assembly 7 includes: a fixed box 70, a sealing door 71, a concave frame 72, a filter plate 73, a partition 74, a Y-shaped tube 75, and a suction hood 76. The linkage assembly 8 includes: a fixed cylinder 80, a movable rod 81, a base plate 82, a rubber plug 83, a connecting plate 84, a rack 85, a stabilizing plate 86, a gear 87, a limiting member 88, a T-shaped plate 880, a spring 881, a rocker arm 89, and a stabilizing rod 800.

[0025] A fixed cylinder 80 is fixed to the top of a fixed box 70, and the bottom of the fixed cylinder 80 is connected to the fixed box 70. A movable rod 81 is piston-connected to the inner wall of the fixed cylinder 80. A base plate 82 is fixed to the bottom of the movable rod 81, and a rubber stopper 83 is fixed to the top of the base plate 82. A stabilizing rod 800 is fixed to the top of the movable rod 81. The top of the stabilizing rod 800 passes through the fixed cylinder 80, and the stabilizing rod 800 is slidably connected to the fixed cylinder 80. A connecting plate 84 is fixed to the top of the stabilizing rod 80, and a rack 85 is fixed to the surface of the connecting plate 84. A stabilizing plate 86 is fixed to the top of the fixed box 70, and a gear 87 is rotatably connected to the surface of the stabilizing plate 86. The gear 87 meshes with the rack 85. The moving component 8 also includes a limiting member 88. By rotating the gear 87 via the rocker arm 89, the two sets of racks 85 rotate in opposite directions. One set of connecting plates 84, stabilizing rods 800, movable rods 81, base plates 82, and rubber plugs 83 move upwards, while the other set of connecting plates 84, stabilizing rods 800, movable rods 81, base plates 82, and rubber plugs 83 move downwards. This causes one set of rubber plugs 83 to block one set of air inlets of the Y-shaped tube 75, while the other set of rubber plugs 83 no longer blocks the other air inlet of the Y-shaped tube 75. At this time, the other set of filter plates 73 performs filtration. Then, the sealing door 71 corresponding to the filter plate 73 that needs to be replaced can be opened, and the filter plate 73 can be pulled out for replacement without stopping the equipment.

[0026] The limiting component 88 includes a T-shaped plate 880, which is slidably connected to the surface of the stabilizing plate 86. A spring 881 is fixed to the bottom of the T-shaped plate 880, and the bottom of the spring 881 is fixed to the top of the fixing box 70. When the T-shaped plate 880 is released, the T-shaped plate 880 is located between the teeth of the gear 87, limiting the gear 87 and preventing the gear 87 from rotating and affecting the filter and subsequent replacement.

[0027] A sealing door 71 is connected to the surface of the fixed box 70. A partition 74 is fixed to the inner wall of the fixed box 70. A concave frame 72 is fixed to the surface of the partition 74 and the inner wall of the fixed box 70. A filter plate 73 is placed on the inside of the concave frame 72. A Y-shaped tube 75 is fixed to the top of the fixed box 70. The Y-shaped tube 75 is connected to the fixed box 70. An air suction hood 76 is fixed to the end of the Y-shaped tube 75 away from the fixed box 70. The end of the air suction hood 76 away from the Y-shaped tube 75 is fixed to the mounting cover 1, and the air suction hood 76 is connected to the mounting cover 1. When the heat exhaust fan 6 is turned on, the air enters the fixed box 70 through the air inlet of the fixed box 70, is filtered by the filter plate 73, and then enters the mounting cover 1 through the Y-shaped tube 75 and the air suction hood 76. Subsequently, the air passes through the heat dissipation fin assembly 4 and dissipates heat from the heat dissipation fin assembly 4.

[0028] An exhaust fan 6 is installed inside the mounting cover 1. An oil supply pipe 2 is fixed on the surface of the mounting cover 1. There are two sets of oil supply pipes 2, and the two sets of oil supply pipes 2 are symmetrically arranged with the center line of the mounting cover 1 as the axis of symmetry. A heat exchange tube bundle 3 is connected between the two sets of oil supply pipes 2, and the heat exchange tube bundle 3 and the oil supply pipe 2 are interconnected. A heat dissipation fin assembly 4 is connected between the heat exchange tube bundles 3. The air force passes through the heat dissipation fin assembly 4 and dissipates heat from the heat dissipation fin assembly 4. The oil is injected from the interface of one set of oil supply pipes 2, and after being dispersed and dissipated by several heat exchange tube bundles 3, it converges on the other set of oil supply pipes 2 and flows out from the top of the other set of oil supply pipes 2.

[0029] The surface of the fixed box 70 is provided with an air inlet hole to allow outside air to enter. There are two sets of concave frame 72, sealing door 71 and filter plate 73. The two sets of concave frame 72, sealing door 71 and filter plate 73 are symmetrically arranged with the center line of the fixed box 70, so that they can be used alternately. There are two sets of fixed cylinder 80, movable rod 81, base plate 82, rubber plug 83, connecting plate 84 and rack 85, which can be alternately blocked to block the air inlet of Y-shaped tube 75, so as to facilitate the replacement of filter plate 73.

[0030] When the exhaust fan 6 is turned on, airflow enters the fixed box 70 through the air inlet, is filtered by the filter plate 73, and then enters the mounting cover 1 through the Y-shaped pipe 75 and the suction hood 76. The airflow then passes through the heat dissipation fin assembly 4 and dissipates heat from it. Oil is injected from the interface of one set of oil pipes 2, dispersed and transferred through several heat exchange tube bundles 3, and then converges into another set of oil pipes 2, flowing out from the top of the other set of oil pipes 2. When the filter plate 73 needs to be replaced after prolonged use, the T-shaped plate 880 is pulled, compressing the spring 881. At this time, the T-shaped plate 880 is no longer positioned between the teeth of the gear 87, and the gear 87 is no longer restricted. The gear 87 can then be rotated by the rocker arm 89, thereby driving the two sets of racks 85 to rotate in opposite directions. At this time, a set of connecting plates 84 and stabilizing... The rod 800, movable rod 81, base plate 82, and rubber plug 83 move upwards, while another set of connecting plates 84, stabilizing rod 800, movable rod 81, base plate 82, and rubber plug 83 move downwards. This causes one set of rubber plugs 83 to block one set of air inlets of the Y-shaped tube 75, while the other set of rubber plugs 83 no longer blocks the other air inlet of the Y-shaped tube 75. The T-shaped plate 880 is then released, positioning itself between the teeth of the gear 87 to limit the gear 87 and prevent it from rotating and affecting filtration and subsequent replacement. At this time, the other set of filter plates 73 begins filtration. The sealing door 71 corresponding to the filter plate 73 that needs to be replaced is then opened, and the filter plate 73 can be pulled out for replacement without stopping the equipment. During installation, the filter plate 73 is inserted into the concave frame 72 for stability, and then the sealing door 71 is closed.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
