Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an external heat dissipation device for air compressors. Background Technology

[0002] An external cooling device for air compressors is an independent device or component used to assist in the heat dissipation of air compressor systems. It is mainly used to solve the heat dissipation problem of air compressors in high-temperature environments or under high loads, ensuring stable operation of the equipment and extending its service life.

[0003] Existing air compressors typically use oil pipes to guide the lubricating oil in the air compressor into the oil-cooled radiator for circulation and heat dissipation. However, the oil-cooled radiator lacks an auxiliary positioning structure for the oil pipe during use. As a result, when the oil pipe is dragged, the pulling force is entirely applied to the interface with the oil-cooled radiator, which can easily lead to loosening and leakage.

[0004] Therefore, in response to the problem that the existing oil-cooled radiators of air compressors lack an oil pipe positioning structure, and the pulling force is concentrated at the interface when dragged, which easily leads to loosening and oil leakage, an external cooling device for air compressors can be designed. Utility Model Content

[0005] To overcome the problem that the existing air compressor's oil-cooled radiator lacks an oil pipe positioning structure, the pulling force is concentrated at the interface when dragging, which easily leads to loosening and oil leakage.

[0006] The technical solution of this utility model is as follows: an external heat dissipation device for an air compressor, including an oil-cooled radiator; it also includes a pressure plate, two fixed frames are installed on the front side of the oil-cooled radiator, each fixed frame is provided with a fixing component, a lead screw is threadedly connected to the front side of the two fixed frames, a rotating seat is rotatably connected to the rear end of the lead screw, a pressure plate is fixed to the rear side of the rotating seat, a limit component is provided on the pressure plate, a knob is installed at the front end of the lead screw, the knob is used to drive the lead screw to rotate, and an installation mechanism is provided at the bottom of the oil-cooled radiator.

[0007] Preferably, by setting a fixed frame, after the oil pipe is connected to the oil cooler, the oil pipe passes through the fixed frame and the pressure plate. Then, the knob is turned, and the knob drives the lead screw to rotate, thereby driving the pressure plate to move back and forth with the cooperation of the limiting component, so as to clamp the oil pipe and achieve the purpose of auxiliary positioning. This solves the problem that existing air compressors usually use oil pipes to guide the lubricating oil in the air compressor into the oil cooler for circulation and heat dissipation. However, the oil cooler lacks an auxiliary positioning structure for the oil pipe during use, which causes the pulling force to be entirely applied at the interface with the oil cooler when the oil pipe is dragged, which can easily lead to loosening and leakage.

[0008] Preferably, the fixing component includes fixing plates and fixing screws. Fixing plates are provided on both the left and right sides of the fixing frame, and fixing screws are connected to the fixing plates. The fixing frame is fixed to the oil cooler by fixing screws.

[0009] Preferably, the limiting assembly includes limiting rods and limiting plates. Two limiting rods are installed on the front side of the pressure plate, and the limiting plates are installed through the front end of the limiting rods through the fixed frame. The limiting rods are slidably connected to the fixed frame.

[0010] Preferably, the mounting mechanism includes a positioning component and a cushioning component. The positioning component is used to fix the oil cooler to the air compressor frame, and the cushioning component is used to provide cushioning for the oil cooler.

[0011] Preferably, the positioning assembly includes a fixing seat and positioning bolts. The fixing seat is installed at the bottom of the oil-cooled radiator, and positioning bolts are provided at both ends of the fixing seat. The fixing seat is fixed to the air compressor frame by the positioning bolts.

[0012] Preferably, the buffer assembly includes springs, and multiple sets of springs are installed at the bottom of the fixing base. The springs are arc-shaped.

[0013] Preferably, the front of the oil-cooled radiator is provided with an observation slot, and a protective glass is embedded inside the observation slot.

[0014] The beneficial effects of this utility model are:

[0015] By using a pressure plate to assist in positioning the oil pipe between the oil cooler and the air compressor, the stability and reliability of the system can be significantly improved. This design effectively disperses the tensile force on the oil pipe, avoiding stress concentration at the interface of the oil cooler, thereby greatly reducing the risk of interface loosening or leakage. At the same time, the auxiliary fixing function of the pressure plate can reduce the displacement of the oil pipe caused by vibration or external force, ensuring that the oil circuit remains sealed for a long time. This improvement not only extends the service life of the oil pipe and the radiator, but also reduces the maintenance frequency, providing a strong guarantee for the continuous and efficient operation of the equipment, and improving the overall safety and economy of the system.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of an external heat dissipation device for an air compressor, including an oil-cooled radiator 1 and a pressure plate 6. Two fixed frames 2 are installed on the front side of the oil-cooled radiator 1, and each fixed frame 2 is provided with a fixing component. A lead screw 4 is threadedly connected to the front side of the two fixed frames 2. A rotating seat 5 is rotatably connected to the rear end of the lead screw 4. The pressure plate 6 is fixed to the rear side of the rotating seat 5. A limit component is provided on the pressure plate 6. A knob 8 is installed at the front end of the lead screw 4. The knob 8 is used to drive the lead screw 4 to rotate. An installation mechanism is provided at the bottom of the oil-cooled radiator 1. By using the fixed frames 2 as the installation base, after the oil pipe is connected to the oil-cooled radiator 1, it passes through the fixed frames 2 and the pressure plate 6 in sequence. By rotating the knob 8, the lead screw 4 is driven to rotate. Under the constraint of the limit component, the pressure plate 6 is axially displaced, thereby clamping and fixing the oil pipe and achieving the function of auxiliary positioning.

[0024] Please see Figures 1-3 In this embodiment, the fixing component includes a fixing plate 31 and a fixing screw 32. Fixing plates 31 are provided on both the left and right sides of the fixing frame 2. Fixing screws 32 are connected to the fixing plates 31. The fixing frame 2 is fixed to the oil cooler 1 by the fixing screws 32. By setting the fixing screws 32, the fixing plates 31 can be fixed to the oil cooler 1, thereby realizing the installation of the fixing frame 2. The limiting component includes a limiting rod 71 and a limiting plate 72. Two limiting rods 71 ​​are installed on the front side of the pressure plate 6. The front end of the limiting rod 71 passes through the fixing frame 2 and the limiting plate 72 is installed. The limiting rod 71 is slidably connected to the fixing frame 2. By setting the limiting rod 71, the rotation of the pressure plate 6 can be restricted, thereby improving the stability and accuracy of clamping.

[0025] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, the installation mechanism includes a positioning component and a buffer component. The positioning component is used to fix the oil cooler 1 to the air compressor frame, and the buffer component is used to provide buffer for the oil cooler 1. The positioning component includes a fixing seat 91 and positioning bolts 92. The fixing seat 91 is installed at the bottom of the oil cooler 1, and positioning bolts 92 are provided at both ends of the fixing seat 91. The fixing seat 91 is fixed to the air compressor frame by the positioning bolts 92. By setting the fixing seat 91 and the positioning bolts 92, the oil cooler 1 can be installed and connected to the air compressor frame. The buffer component includes spring pieces 93. Multiple sets of spring pieces 93 are installed at the bottom of the fixing seat 91. The spring pieces 93 are arc-shaped. By setting the spring pieces 93, the elastic potential energy of the spring pieces 93 can provide buffer for the bottom of the oil cooler 1. An observation slot 10 is opened on the front side of the oil cooler 1. A protective glass 11 is embedded in the observation slot 10. By setting the observation slot 10 and the protective glass 11, it is convenient for the staff to observe the circulation of lubricating oil inside the oil cooler 1.

[0026] During installation, the fixed frame 2 is first fixed to the front of the oil cooler 1 using the fixing plate 31 and fixing screw 32. The oil pipe passes through the fixed frame 2 and the pressure plate 6. By turning the knob 8, the lead screw 4 is driven to rotate. The lead screw 4 pushes the rotating seat 5 at the rear end and the pressure plate 6 to move back and forth along the direction of the limit rod 71. The limit rod 71 passes through the fixed frame 2 and the end is equipped with the limit plate 72 to prevent the pressure plate 6 from rotating. The pressure plate 6 presses the oil pipe tightly onto the fixed frame 2 to prevent the oil pipe from being pulled by external force, which could cause the interface to loosen and leak. The fixed seat 91 at the bottom of the oil cooler 1 is rigidly connected to the air compressor frame by the positioning bolt 92. At the same time, multiple sets of arc-shaped springs 93 installed below the fixed seat 91 absorb vibration through elastic deformation, providing a buffer for the oil cooler 1. The operator can monitor the internal lubricating oil circulation status in real time through the observation slot 10 and the embedded protective glass 11 on the front of the oil cooler 1.

[0027] Through the above steps, after the oil pipe is connected to the oil cooler 1, its body passes through the reserved channel of the fixed frame 2 and extends to the position of the pressure plate 6. During operation, rotating the knob 8 drives the lead screw 4 to rotate, and the rotational motion is converted into linear motion through the threaded transmission. Under the guidance of the limit component, the pressure plate 6 moves in the set direction and applies radial pressure to the oil pipe, thereby forming a stable clamping state. This solves the problem that existing air compressors usually use oil pipes to guide the lubricating oil in the air compressor into the oil cooler 1 for circulation and heat dissipation. However, the oil cooler 1 lacks an auxiliary positioning structure for the oil pipe during use, which causes the pulling force to be applied to the interface with the oil cooler 1 when the oil pipe is dragged, which easily leads to loosening and leakage.
