Description

Technical Field

[0001] The utility model relates to the field of sheet metal fin cleaning, in particular to a cleaning device for sheet metal fins of an oil cooler. Background Art

[0002] Oil cooler is also called oil chiller. According to the principle of refrigeration system, low-temperature and low-pressure liquid refrigerant exchanges heat with the surrounding water in the evaporator. The evaporator absorbs the heat of the oil and evaporates into a low-temperature and low-pressure gas. The temperature of the refrigerant does not change during the evaporation process. The low-temperature and low-pressure gaseous refrigerant enters the compressor, is compressed by the compressor, and is compressed into a high-temperature and high-pressure gas. Then it enters the condenser and exchanges heat with the indoor medium in the condenser. Part of the heat of the high-temperature and high-pressure gas is absorbed by the medium, the temperature of the medium rises, and the refrigerant releases heat to become a high-temperature and high-pressure liquid. The temperature of the condenser process remains unchanged, and then it enters the expansion valve for throttling. Throttling is a process of rapid cooling. The refrigerant becomes a low-temperature and low-pressure liquid. After this process, the refrigerant enters the evaporator for heat exchange and evaporation, thereby realizing the entire process of the refrigeration system.

[0003] Oil cooler sheet metal fins are an important component in oil coolers and are usually used to enhance heat dissipation. The design of the fins can increase the heat dissipation area, thereby more effectively transferring heat to the air and helping the oil cooler maintain an appropriate temperature. The choice of sheet metal material allows the fins to have a certain strength and durability while maintaining a light weight for easy installation and maintenance.

[0004] In addition, the shape, size and arrangement of the fins will also affect their heat dissipation performance. For example, parameters such as fin spacing, fin height and fin thickness need to be optimized according to the specific application scenario to achieve the best heat dissipation effect. Therefore, the design and manufacture of sheet metal fins for oil coolers require certain professional knowledge and technical strength. In related technologies, the fins are generally held by one hand and the cleaning nozzle is held by the other hand to clean them. Although manual cleaning has a good fin cleaning effect, it wastes a lot of time and manpower, and is inefficient when more fins need to be cleaned.

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a cleaning device for sheet metal fins of an oil cooler provided by the utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the rear view of the frame shown; Figure 3 for Figure 1 The schematic diagram of the structure of the flip frame part is a cleaning device for the sheet metal fins of an oil cooler, comprising: a frame 1, a cleaning component 2 is arranged on the inner side of the frame 1, and a fixing component 3 is arranged on the inner side of the frame 1;

[0023] The cleaning assembly 2 includes a gantry 21 which is slidable left and right and is arranged on the top of the frame 1. A brush roller 22 is rotatably arranged on the inner side of the gantry 21. A group of nozzles are arranged on the top of the inner side of the gantry 21.

[0024] The two telescopic cylinders 26 drive the gantry 21 to move left and right on the frame 1, thereby driving the rotating brush roller 22 to move left and right, so as to clean the surface of the placed fins, and cooperate with the spraying nozzle to achieve a better cleaning effect.

[0025] The fixing assembly 3 comprises a U-shaped frame 31 rotatably arranged inside the frame 1 , a flip frame 32 is arranged inside the U-shaped frame 31 , and two support blocks 33 are arranged inside the flip frame 32 so as to slide left and right along its length direction.

[0026] After placing the fins to be cleaned on opposite sides of the two support blocks 33, the fins are fixed by moving the two support blocks 33 relative to each other to avoid displacement during the flushing process. Moreover, by setting the rotatable U-shaped frame 31, when one side of the fin is cleaned, it can be turned over to clean the other side, and the cleaning efficiency is high.

[0027] A water tank 23 is provided on the inner side of the frame 1 and below the gantry 21 , a water pump 24 is provided in the middle part of the front side of the water tank 23 , a water outlet at the top of the water pump 24 is connected to a bellows 25 , and the top end of the bellows 25 is connected to the interface of the nozzle at the bottom front side of the gantry 21 .

[0036] Step 1: When in use, place the fin to be cleaned on the opposite side of the two support blocks 33, and then drive the rotation of the screw rod 35 by rotating the rocker 37, thereby driving the relative movement of the two support blocks 33, so that the left and right sides of the fin are firmly clamped to prevent it from shifting during cleaning;

[0037] Step 2: The two telescopic cylinders 26 drive the gantry 21 to move left and right on the frame 1, thereby driving the rotating brush roller 22 to move left and right, and cleaning the surface of the placed fins. With the spraying nozzle, the cleaning effect is better.

[0038] Step 3: After one side of the fin is cleaned, the rotation of the output end of the second motor 38 drives the rotation of the left U-shaped frame 31, and then drives the rotation of the entire flip frame 32, so that the other side of the fin is facing up, and the brush roller 22 and the nozzle are used for cleaning. The cleaned water will be filtered and then flow back to the water tank 23, saving water resources.

[0039] Compared with the related art, the cleaning device for oil cooler sheet metal fins provided by the utility model has the following beneficial effects:

[0040] The rotating screw rod 35 is driven to rotate by rotating the rocker 37, and then the two support blocks 33 are driven to move relative to each other, so that the left and right sides of the fins are firmly clamped. The gantry 21 is driven to move left and right on the frame 1 by the two telescopic cylinders 26, and then the brush roller 22 in rotation is driven to move left and right to clean the surface of the placed fins.
