Description

Technical Field

[0001] This utility model relates to the technical field of condenser maintenance equipment, and in particular to a cleaning structure for finned condensers. Background Technology

[0002] Finned condensers increase the heat dissipation area through densely arranged metal fins and are widely used in air conditioning, refrigeration equipment and other fields. However, with long-term use, dust, oil, catkins and other debris can easily accumulate on the fin surface, leading to a decrease in heat dissipation efficiency, increased energy consumption and even equipment failure.

[0003] Most of the heat exchange fins in existing finned condensers are fixed and require manual cleaning. This prevents the heat exchange fins from quickly dissipating the heat generated by the condenser body during long-term operation, reducing the heat dissipation effect of the heat exchange fins and increasing the workload of manual cleaning.

[0004] An existing patent (publication number: CN220670302U) discloses a condenser that is easy to clean. It is equipped with an electric push rod, a push rod, and a cleaning brush. When the condenser body is running for a long time, the heat exchange fins exhaust the hot air generated by the operation of the condenser body. The electric push rod, which is fixed to the bottom of the support plate, rotates. The push rod connected to the bottom of the electric push rod drives the second mounting block to move with the rotation of the electric push rod. The cleaning brushes, which are arranged in sequence on the second mounting block, clean the dust adsorbed on the heat exchange fins as the second mounting block moves, thereby improving the heat dissipation effect of the heat exchange fins and reducing the cleaning work of the staff.

[0005] Existing patents offer solutions to the above problems, but their cleaning effects are unsatisfactory. In actual use, due to the lack of a dust suction structure, some of the dust, catkins, and other light debris swept away by the brush are easily left in the gaps between the fins and cannot be completely removed from the condenser. At the same time, the long-term residual impurities will accelerate the oxidation and corrosion of the fins, affecting the service life and heat dissipation efficiency of the condenser and reducing the practicality of the device.

[0006] To address this, a clean structure for finned condensers is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a cleaning structure for finned condensers, which can solve the problem that the existing finned condensers have poor cleaning effect. In actual use, due to the lack of a dust suction structure, some of the dust, catkins and other light debris swept by the brush are easily left in the gaps between the fins and cannot be completely removed from the condenser. At the same time, the long-term residual impurities will accelerate the oxidation and corrosion of the fins, affecting the service life and heat dissipation efficiency of the condenser, and reducing the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cleaning structure for a finned condenser, comprising a condenser body, a fixed frame fixedly connected to the front side of the condenser body, a filter screen movably connected to the side of the fixed frame away from the condenser body, a brush assembly fixedly connected inside the fixed frame, and a collection assembly fixedly connected to the bottom of the fixed frame, the collection assembly comprising a U-shaped storage block, a conveying pipe fixedly connected to the left side of the top of the U-shaped storage block, and a discharge valve fixedly connected to the right side of the bottom of the U-shaped storage block, a collection hopper fixedly connected to the side of the conveying pipe away from the U-shaped storage block, and the collection hopper fixedly connected to the bottom of the fixed frame, a gas delivery hose fixedly connected to the right side of the U-shaped storage block, and a fan fixedly connected to the side of the gas delivery hose away from the U-shaped storage block, a trapezoidal guide block fixedly connected to the bottom of the inner wall of the U-shaped storage block, and the discharge valve located at the bottom of the slope of the trapezoidal guide block.

[0009] Preferably, the brush assembly includes a fixing plate, on both sides of the top of the fixing plate are fixedly connected to rotating motors, and the fixing plate is fixedly connected to the rear side of the top of the fixing frame. The output ends of the two rotating motors are fixedly connected to threaded rods, and the other end of the threaded rods extends into the interior of the fixing frame. The surfaces of the two threaded rods are threadedly connected to sliders, and the top of the surfaces of the two threaded rods are fixedly connected to rotating gears. A brush roller is rotatably connected between the two sliders, and the brush roller contacts the fins on the front side of the condenser body. Chains are wound around the surfaces of the two rotating gears, and the rotating gears are located inside the fixing plate.

[0010] Preferably, both sliders have threaded holes inside for use with threaded rods, and the surface of the threaded rod is in contact with the inner wall of the threaded hole.

[0011] Preferably, the fixed plate has a connecting groove inside, and the rotating gear and chain are located inside the connecting groove.

[0012] Preferably, the exhaust end of the fan is fixedly connected to an exhaust pipe, and a trapezoidal exhaust plate is fixedly connected to the side of the exhaust pipe away from the fan.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application, by setting up a brush assembly, can drive the threaded rod to rotate through a rotating motor. The synchronous transmission of the chain and rotating gear makes the threaded rods on both sides move in the same direction, driving the slider and brush roller to rise and fall smoothly. The brush roller contacts the condenser fins and generates friction, causing the brush roller to rotate smoothly and complete the cleaning of dust on the fin surface. At the same time, with the help of the exhaust structure composed of the exhaust pipe and the trapezoidal exhaust plate, airflow can be sprayed onto the fins to assist in the cleaning of dust, thus improving the cleaning efficiency of the finned condenser.

[0018] 2. This application, by setting up a collection component, can collect the debris generated during cleaning through a collection hopper and guide it into a U-shaped storage block through a conveying pipe. At the same time, a fan draws air out of the U-shaped storage block to create negative pressure, generating suction force, which draws the dust floating in the fixed frame into the U-shaped storage block for temporary storage. With the help of a filter cover, it can prevent debris from entering the air delivery hose and damaging the fan, ensuring the normal use of the dust collection function. The dust entering the U-shaped storage block is guided by the trapezoidal guide block to gather at the discharge valve, and then the debris is discharged in a concentrated manner through the discharge valve, which improves the practicality of the device.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A cleaning structure for a finned condenser includes a condenser body 1. A fixing frame 2 is fixedly connected to the front side of the condenser body 1, and a filter screen 3 is movably connected to the side of the fixing frame 2 away from the condenser body 1. A brush assembly 4 is fixedly connected inside the fixing frame 2, and a collection assembly 5 is fixedly connected to the bottom of the fixing frame 2. The collection assembly 5 includes a U-shaped storage block 501. A conveying pipe 502 is fixedly connected to the left side of the top of the U-shaped storage block 501, and a conveying pipe 502 is fixed to the right side of the bottom of the U-shaped storage block 501. A discharge valve 503 is connected to the conveying pipe 502. A collection hopper 504 is fixedly connected to the side of the U-shaped storage block 501 away from the U-shaped storage block 501, and the collection hopper 504 is fixedly connected to the bottom of the fixed frame 2. A gas delivery hose 505 is fixedly connected to the right side of the U-shaped storage block 501, and a fan 506 is fixedly connected to the side of the gas delivery hose 505 away from the U-shaped storage block 501. A trapezoidal guide block 507 is fixedly connected to the bottom of the inner wall of the U-shaped storage block 501, and the discharge valve 503 is located at the bottom of the slope of the trapezoidal guide block 507.

[0028] In this embodiment: the rotating motor 402 drives the threaded rod 403 to rotate, synchronously driving the rotating gear 405 to rotate. Under the transmission of the chain 407, the two threaded rods 403 move synchronously in the same direction, causing the slider 404 and the brush roller 406 to rise and fall smoothly. The brush roller 406 contacts the condenser fins to generate friction and rotates smoothly, completing the efficient cleaning of dust on the fin surface and improving the ease of use of the brush assembly 4. Then, through the cooperation of the collection bucket 504 and the conveying pipe 502, the debris generated during cleaning can be collected in real time and conveyed through the conveying pipe. The dust is temporarily stored in the U-shaped storage block 501, which, together with the trapezoidal guide block 507, forms a flow guiding structure. This structure guides the dust falling into the U-shaped storage block 501 to gather at the discharge valve 503. The discharge valve 503 then discharges the debris. At the same time, the blower 506 draws air out of the U-shaped storage block 501 through the air hose 505 to create a negative pressure. This generates suction, causing the dust floating in the fixed frame 2 to be drawn into the U-shaped storage block 501 through the collection hopper 504 and the conveying pipe 502 for temporary storage. This improves the dust cleaning efficiency.

[0029] Specifically, such as Figure 4 As shown, the brush assembly 4 includes a fixing plate 401. Rotary motors 402 are fixedly connected to both sides of the top of the fixing plate 401. The fixing plate 401 is fixedly connected to the rear side of the top of the fixing frame 2. Threaded rods 403 are fixedly connected to the output ends of the two rotary motors 402. The other end of the threaded rods 403 extends into the interior of the fixing frame 2. Slider blocks 404 are threadedly connected to the surfaces of the two threaded rods 403. Rotary gears 405 are fixedly connected to the top of the surfaces of the two threaded rods 403. A brush roller 406 is rotatably connected between the two sliders 404. The brush roller 406 contacts the fins on the front side of the condenser body 1. Chains 407 are wound around the surfaces of the two rotating gears 405. The rotating gears 405 are located inside the fixing plate 401.

[0030] Specifically, such as Figure 4 As shown, both sliders 404 have threaded holes 6 inside for use with threaded rods 403, and the surface of the threaded rods 403 is in contact with the inner wall of the threaded holes 6.

[0031] Specifically, such as Figure 4 As shown, the fixed plate 401 has a connecting groove 7 inside, and the rotating gear 405 and the chain 407 are located inside the connecting groove 7.

[0032] In this embodiment: the connecting groove 7 provides operating space for the transmission structure formed by the rotating gear 405 and the chain 407, allowing the threaded rods 403 on both sides to move synchronously and in the same direction, preventing jamming and laying the foundation for the smooth movement of the slider 404. At the same time, through the cooperation of the threaded rod 403 and the threaded hole 6, the slider 404 can move smoothly along the threaded rod 403, synchronously driving the brush roller 406 to move. The brush roller 406 contacts the condenser fins to generate friction and rotates smoothly, completing the efficient cleaning of dust on the fin surface and improving the dust cleaning effect.

[0033] Specifically, such as Figure 2 , Figure 5 As shown, an exhaust pipe 8 is fixedly connected to the exhaust end of the fan 506, and a trapezoidal exhaust plate 9 is fixedly connected to the side of the exhaust pipe 8 away from the fan 506. The trapezoidal exhaust plate 9 is fixedly connected to the top of the inner wall of the fixed frame 2, and the exhaust direction of the trapezoidal exhaust plate 9 is aligned with the fins of the condenser body 1.

[0034] Specifically, such as Figure 5 As shown, a filter cover 10 is fixedly connected to the right side of the inner wall of the U-shaped storage block 501, and the connection end of the gas delivery hose 505 and the U-shaped storage block 501 is located inside the filter cover 10.

[0035] In this embodiment: the filter cover 10 forms a filter structure that can block air carrying impurities from entering the fan 506 through the air delivery hose 505 in real time, preventing damage to the fan 506 due to impurities and ensuring the normal operation of the dust collection function. At the same time, with the help of the exhaust structure formed by the exhaust pipe 8 and the trapezoidal exhaust plate 9, the air drawn out by the fan 506 is delivered to the trapezoidal exhaust plate 9 through the exhaust pipe 8, and then the trapezoidal exhaust plate 9 precisely sprays it onto the fins of the condenser body 1. This can not only assist the condenser in heat dissipation and improve the operating efficiency of the equipment, but also blow off the floating dust attached to the surface of the fins to assist in dust cleaning, reduce dust residue, ensure the heat dissipation effect of the equipment, and improve the convenience of using the collection component 5.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, the top and bottom of the front side of the fixed frame 2 are fixedly connected to the positioning plate 11, the filter screen 3 is movably connected to the surface of the positioning plate 11, and the front side of the positioning plate 11 is rotatably connected to the buckle block 12.

[0037] Specifically, such as Figure 2 , Figure 3 As shown, the top and bottom of the filter screen 3 are provided with positioning holes 13 for use with the positioning plate 11, and the surface of the positioning plate 11 is in contact with the inner wall of the positioning hole 13.

[0038] In this embodiment, the positioning plate 11 and the positioning hole 13 work together to form a guiding structure, allowing the filter screen 3 to move smoothly towards the fixed frame 2 under the restriction of the positioning plate 11, so that the filter screen 3 and the fixed frame 2 are precisely aligned. After moving into place, the buckle block 12 is rotated to lock the filter screen 3, enabling quick installation and removal of the filter screen 3, facilitating cleaning of the filter screen 3, ensuring the air filtration effect, ensuring the cleanliness of the air entering the condenser body 1, reducing the accumulation of dirt on the fins to maintain heat dissipation efficiency, and improving the ease of use of the device.

[0039] Working Principle: When the finned condenser is running, first manually rotate the latch block 12 to release the lock on the filter screen 3, allowing the filter screen 3 to be removed for cleaning. After cleaning, align the positioning hole 13 on the surface of the filter screen 3 with the positioning plate 11 and push it into place. Rotate the latch block 12 to lock it, making the filter screen 3 tightly connected to the condenser body 1, forming a pre-filter barrier that intercepts large particulate impurities in the air in real time, ensuring the cleanliness of the air entering the condenser body 1, reducing fin buildup and maintaining heat dissipation efficiency. When cleaning is required after a period of operation, start the rotating motor 402 to drive the threaded rod 403 to rotate, synchronously driving the rotating gear 405 to rotate. Through the transmission of the chain 407, the two threaded rods 403 move synchronously in the same direction, driving the slider 404 and the brush roller 406 to rise and fall smoothly. The brush roller 406 contacts the condenser fins, generating friction and rotating smoothly. Through mechanical cleaning, it can efficiently remove the deposits on the fin surface and in the gaps. Dust and grime fall steadily into the collection hopper 504, and are then transported to the U-shaped storage block 501 for temporary storage via the conveying pipe 502. Simultaneously, the fan 506 is activated to generate suction, which draws air out of the U-shaped storage block 501 through the air delivery hose 505, creating negative pressure. This suction draws the dust scattered in the fixed frame 2 through the collection hopper 504 and the conveying pipe 502 into the U-shaped storage block 501 for temporary storage. The dust entering the U-shaped storage block 501 is guided by the trapezoidal guide block 507 to gather at the discharge valve 503, where it is then discharged. In addition, the air drawn out by the fan 506 is transported to the trapezoidal exhaust plate 9 via the exhaust pipe 8, and then precisely sprayed onto the fins of the condenser body 1. This not only assists in condenser heat dissipation and improves equipment operating efficiency, but also blows off the floating dust attached to the fin surface, forming a cleaning synergy with the brush assembly 4 to further improve the dust cleaning effect.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
