Description

Technical Field

[0001] The invention relates to the technical field of air condensation, and in particular to a fin tube bundle structure of an air condenser. Background Art

[0002] Air condensation technology is based on the process that when gaseous substances come into contact with low-temperature air, the heat of the gaseous substances is absorbed by the air through heat transfer, thereby reducing its temperature, reaching a saturated state and undergoing a phase change, from gas to liquid. In this process, heat transfer is mainly carried out by convection. For example, in the air condenser of the refrigeration system, high-temperature and high-pressure refrigerant vapor enters the condenser and exchanges heat with the surrounding air through heat exchange structures such as finned tubes. After the air absorbs the heat of the refrigerant, the temperature rises, and the refrigerant gradually condenses into liquid due to heat release. The finned tube bundle structure of the air condenser is mainly composed of multiple finned tubes, or tube sheets and frames;

[0003] The tube bundles of the air-cooling system are deformed after long-term operation. The gaps between the tube bundles of the air-cooling units gradually increase, resulting in a waste of air volume and a gradual decrease in heat exchange efficiency. It is necessary to improve the gap sealing method to increase the air volume utilization rate. At present, the fin gaps between the air-cooling units are of different sizes and are sealed with sponge strips, filling glue, rubber strips, etc. Due to airflow and tube bundle deformation, the sealing strips have fallen off many times, which not only failed to achieve the sealing effect, but also caused hidden dangers to the operation of the fan below. Summary of the invention

[0004] The main purpose of the present invention is to provide an air condenser fin tube bundle structure, by adjusting the structure, the heat exchange efficiency of the condenser tube can be adjusted.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] An air condenser fin tube bundle structure comprises a condenser tube, wherein the outer surface of the condenser tube is provided with a plurality of groups of first fins, and the outer surface of the condenser tube is provided with an adjustment structure at the position of each group of first fins;

[0007] The adjustment structure includes a connecting ring and a plurality of hollow blocks. The connecting ring is installed on the outer surface of the condenser and is located at the position of a group of first fins. Each group of first fins is composed of twelve first fins. The plurality of hollow blocks are equidistantly slidably connected to the outer surface of the connecting ring. Two second fins are arranged between two adjacent first fins. Two rotating grooves are provided on the top of the first fin and the top of the second fin, and two rotating blocks are fixedly connected to the bottom of the first fin and the bottom of the second fin.

[0008] As a further solution of the present invention, the outer surface of the condenser is connected to a limiting ring near the front and rear parts, the outer surfaces of the two limiting rings are symmetrically and fixedly connected with connecting blocks, the two groups of connecting blocks symmetrically arranged at the front and rear parts are rotatably connected with screws, two of the first fins in each group of first fins are provided with through grooves at the front and rear parts, six connecting rods are equidistantly rotatably connected to the inner walls of the through grooves, the close ends of the six connecting rods are rotatably connected with hollow rings, and the screws penetrate the hollow rings.

[0009] As a further solution of the present invention, the two limiting rings are provided with grooves at the top, and the outer surfaces of the condenser are provided with slots at the top of the front and rear parts. An insertion rod is installed inside the slots through the outer surfaces of the limiting rings. The outer surface of the insertion rod is located inside the grooves and is fixedly connected with a clamping block, which is adaptively matched with the clamping block.

[0010] As a further solution of the present invention, the outer surfaces of the two screws located at the front of each through slot are threadedly connected to movable block one, and the outer surfaces of the two screws located at the rear of each through slot are threadedly connected to movable block two, a telescopic connecting rod is rotatably connected between the rear of movable block one and the front of the hollow ring, and a telescopic connecting rod is also rotatably connected between the front of movable block two and the rear of the hollow ring.

[0011] As a further solution of the present invention, a rotating drum 1 is fixedly connected between several movable blocks 1, and one end of the rotating drum 1 passes through the rear part of the connecting block at the rear, and a rotating drum 2 is fixedly connected between several movable blocks 2, and the rotating drum 2 passes through the rear part of the connecting block at the rear.

[0012] As a further solution of the present invention, the rotating drum 1 is located on the outer surface of the screw, and the rotating drum 1 is threadedly connected to the screw, and the rotating drum 2 is rotatably connected to the rotating drum 1 through a thread groove.

[0013] As a further solution of the present invention, the inner wall diameter of the hollow ring is larger than the diameter of the first rotating drum, the rotating block is rotatably connected to the rotating groove, and the hollow block is fixedly connected to the first fin.

[0014] The above-mentioned embodiment of the present invention can achieve the following beneficial effects: by adjusting the structure, each group of first fins is slid along the connecting ring, and the first fins slide along the outer surface of the connecting ring through the hollow block, so that each first fin is gradually spaced apart from the outer surface of the connecting ring, and the plurality of second fins are rotated, thereby reducing the heat exchange efficiency of the condenser tube through the first fins and the second fins. Therefore, by adjusting the distance between each first fin and the distance between the plurality of second fins in each group of first fins, the heat exchange efficiency of the condenser tube can be adjusted;

[0015] By setting the screw rod to cooperate with the movable block one and the movable block two, the insertion rod is rotated ninety degrees, and the position of the block matches the top shape of the slot. At this time, the insertion rod is pulled up to separate the block from the slot and the insertion rod is out of the slot. At this time, the limit ring can rotate along the center of the condenser tube along the center of the screw rod, and the screw rod is rotated to drive the movable block one to slide linearly along the outer surface of the screw rod. The movable block one moves, driving the rotating drum one to rotate together, and then driving the rotating drum two and the movable block two to move together, and then driving the hollow ring and the first fin to move together through the connecting rod. Since the front and rear parts of the hollow ring are connected to the movable block one and the movable block two through the telescopic connecting rod, the front and rear parts of the hollow ring are restricted, and the first fin cannot rotate back and forth along the connecting ring through the hollow ring, and then only the distance between each group of first fins can be adjusted, and then the heat exchange efficiency of the condenser tube can be further adjusted;

[0016] By setting the rotating drum one and the rotating drum two, only the rotating drum one is rotated, and the rotating drum two does not rotate, and then the hollow ring is driven to move forward through the telescopic connecting rod, while the rotating drum two does not move, so that the rotating drum one rotates to drive the movable block one to move forward, so that the hollow ring is driven to move forward, and then the first fin is driven to rotate toward the front along the outer surface of the connecting ring, and only the rotating drum two is rotated, and the rotating drum one does not rotate, and then the hollow ring is driven to move backward through the telescopic connecting rod, and the rotating drum one does not move, and then the rotating drum two rotates to drive the rear of the movable block two, so that the hollow ring is driven to move backward, and then the first fin is driven to rotate toward the rear along the outer surface of the connecting ring, and the angle of the first fin can be adjusted by rotating the rotating drum one or the rotating drum two, and then the angle between the fin tube and the air flow direction can be changed, and the heat exchange efficiency of the condenser tube can be further adjusted;

[0017] Moreover, by changing the angle of each group of first fins and the spacing between each group of first fins, the first fins and the sponge strips can be squeezed against each other, and the sponge strips cannot be separated, thus causing no hidden danger to the operation of the fan under the fin tube bundle structure of the air condenser.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figure 1 - Figure 8 As shown, an air condenser fin tube bundle structure includes a condenser tube 1, a plurality of groups of first fins 3 are arranged on the outer surface of the condenser tube 1, and an adjustment structure 4 is arranged on the outer surface of the condenser tube 1 at the position of each group of first fins 3;

[0029] The adjustment structure 4 includes a connecting ring 2 and a plurality of hollow blocks 22. The connecting ring 2 is installed on the outer surface of the condenser tube 1 and is located at the position of a group of first fins 3. Each group of first fins 3 is composed of twelve first fins 3. The plurality of hollow blocks 22 are equidistantly slidably connected to the outer surface of the connecting ring 2. Two second fins 8 are arranged between two adjacent first fins 3. The top of the first fin 3 and the top of the second fin 8 are both provided with two rotation grooves 10. The bottom of the first fin 3 and the bottom of the second fin 8 are both fixedly connected with two rotating blocks 9.

[0030] Each group of first fins 3 is slid along the connecting ring 2, and the first fins 3 slide along the outer surface of the connecting ring 2 through the hollow block 22, so that each first fin 3 is gradually spaced apart from the outer surface of the connecting ring 2, and several second fins 8 are rotated, thereby reducing the heat exchange efficiency of the condenser 1 through the first fins 3 and the second fins 8. Therefore, by adjusting the distance between each first fin 3 and the distance between several second fins 8 in each group of first fins 3, the heat exchange efficiency of the condenser 1 can be adjusted.

[0031] In this embodiment, the outer surface of the condenser 1 is connected to a limiting ring 5 near the front and rear parts, and the outer surfaces of the two limiting rings 5 ​​are symmetrically and fixedly connected with connecting blocks 6, and screws 7 are rotatably connected between the two groups of connecting blocks 6 symmetrically at the front and rear parts. Two of the first fins 3 in each group of first fins 3 are provided with through grooves 11 at the front and rear parts, and six connecting rods 12 are rotatably connected to the inner walls of the through grooves 11 at equal intervals, and the close ends of the six connecting rods 12 are rotatably connected with hollow rings 13, and the screws 7 penetrate the hollow rings 13. By rotating two screws 7 along the center of the condenser 1, the distance between each first fin 3 in each group of first fins 3 can be controlled.

[0032] In this embodiment, the two limiting rings 5 ​​are provided with a card slot 14 at the top, and the outer surface of the condenser tube 1 is provided with a slot 23 at the top of the front and rear parts. The slot 23 penetrates through the outer surface of the limiting ring 5 and is provided with a plug rod 15. The outer surface of the plug rod 15 is located inside the card slot 14 and is fixedly connected with a card block 16. The card block 16 is adaptively matched with the card slot 14.

[0033] Rotate the insertion rod 15 ninety degrees, and the position of the block 16 matches the top shape of the slot 14. At this time, pull up the insertion rod 15 to separate the block 16 from the slot 14, and the insertion rod 15 disengages from the slot 23. At this time, the limit ring 5 can rotate along the center of the condenser 1 together with the first fin 3.

[0034] In this embodiment, the outer surfaces of the two screw rods 7 are located at the front of each through slot 11 and are threadedly connected to the movable block 17, and the outer surfaces of the two screw rods 7 are located at the rear of each through slot 11 and are threadedly connected to the movable block 2 19, and the rear of the movable block 17 and the front of the hollow ring 13 are rotatably connected to the telescopic connecting rod 18, and the front of the movable block 2 19 and the rear of the hollow ring 13 are also rotatably connected to the telescopic connecting rod 18;

[0035] The screw rod 7 is rotated along the center of the circle of the screw rod 7, and the movable block 17 is driven to slide linearly along the outer surface of the screw rod 7. The movable block 17 moves, and drives the rotating drum 20 to rotate together, and then drives the rotating drum 21 and the movable block 2 19 to move together, and then drives the hollow ring 13 and the first fin 3 to move together through the connecting rod 12. Since the front and rear parts of the hollow ring 13 are connected to the movable block 17 and the movable block 2 19 through the telescopic connecting rod 18, the front and rear parts of the hollow ring 13 are restricted, and the first fin 3 cannot be rotated forward and backward along the connecting ring 2 through the hollow ring 13, and can only adjust the distance between each group of first fins 3, so as to further adjust the heat exchange efficiency of the condenser tube 1.

[0036] In this embodiment, a rotating drum 20 is fixedly connected between several movable blocks 17, and one end of the rotating drum 20 passes through the rear of the connecting block 6 at the rear. A rotating drum 21 is fixedly connected between several movable blocks 2 19, and the rotating drum 21 passes through the rear of the connecting block 6 at the rear.

[0037] In this embodiment, the drum 1 20 is located on the outer surface of the screw 7, and the drum 1 20 is threadedly connected to the screw 7, and the drum 2 21 is located on the outer surface of the drum 1 20;

[0038] Only the drum 1 20 is rotated, and the drum 2 21 does not rotate, and then the hollow ring 13 is driven forward by the telescopic connecting rod 18, while the drum 2 21 does not move, so that the drum 1 20 rotates to drive the movable block 17 to move forward, so that the hollow ring 13 is driven forward, and then the first fin 3 is driven to rotate forward along the outer surface of the connecting ring 2, and only the drum 2 21 is rotated, and the drum 1 20 does not rotate, and then the hollow ring 13 is driven backward by the telescopic connecting rod 18, and the drum 1 20 does not move, so that the drum 2 21 rotates to drive the rear of the movable block 2 19, so that the hollow ring 13 is driven backward, and then the first fin 3 is driven to rotate backward along the outer surface of the connecting ring 2, and the angle of the first fin 3 can be adjusted by rotating the drum 1 20 or the drum 2 21, and then the angle between the fin tube and the air flow direction can be changed, and the heat exchange efficiency of the condenser tube 1 can be further adjusted;

[0039] Furthermore, the angle of each group of first fins 3 and the distance between each group of first fins 3 are changed, so that the first fins 3 and the sponge strips can be squeezed against each other, and the sponge strips cannot be separated, thereby not causing hidden dangers to the operation of the fan under the air condenser fin tube bundle structure.

[0040] In this embodiment, the inner wall diameter of the hollow ring 13 is larger than the diameter of the rotating drum 20 , the rotating block 9 is rotatably connected to the rotating groove 10 , and the hollow block 22 is fixedly connected to the first fin 3 .

[0041] It should be noted that the present invention is an air condenser fin tube bundle structure. When the tube bundle of the air cooling system is deformed after long-term operation, so that the tube bundle gap between the air cooling units gradually increases, a stable sponge strip is installed on the outer surface of the condenser tube 1 and located between two adjacent groups of first fins 3, thereby completing the gap between the two adjacent condenser tubes 1.

[0042] Each group of first fins 3 is slid along the connecting ring 2, and the first fins 3 slide along the outer surface of the connecting ring 2 through the hollow block 22, so that each first fin 3 is gradually spaced apart on the outer surface of the connecting ring 2, and the plurality of second fins 8 are rotated, thereby reducing the heat exchange efficiency of the condenser 1 through the first fins 3 and the second fins 8. Therefore, by adjusting the distance between each first fin 3 and the distance between the plurality of second fins 8 in each group of first fins 3, the heat exchange efficiency of the condenser 1 can be adjusted;

[0043] The plug rod 15 is rotated 90 degrees. At this time, the position of the block 16 matches the top shape of the slot 14. At this time, the plug rod 15 is pulled up to separate the block 16 from the slot 14, and the plug rod 15 is disengaged from the slot 23. At this time, the limit ring 5 can rotate along the center of the condenser tube 1 with the first fin 3. Along the center of the screw 7, the screw 7 is rotated to drive the movable block 17 to slide linearly along the outer surface of the screw 7. The movable block 17 moves, drives the rotating drum 1 20 to rotate together, and then drives the rotating drum 2 21 and the movable block 2 19 to move together, and then drives the hollow ring 13 and the first fin 3 to move together through the connecting rod 12. Since the front and rear parts of the hollow ring 13 are connected to the movable block 17 and the movable block 2 19 through the telescopic connecting rod 18, the front and rear parts of the hollow ring 13 are restricted, and the first fin 3 cannot be rotated forward and backward along the connecting ring 2 through the hollow ring 13, and then only the distance between each group of first fins 3 can be adjusted, and then the heat exchange efficiency of the condenser tube 1 is further adjusted;

[0044] Only the drum 1 20 is rotated, and the drum 2 21 does not rotate, and then the hollow ring 13 is driven forward by the telescopic connecting rod 18, while the drum 2 21 does not move, so that the drum 1 20 rotates to drive the movable block 17 to move forward, so that the hollow ring 13 is driven forward, and then the first fin 3 is driven to rotate forward along the outer surface of the connecting ring 2, and only the drum 2 21 is rotated, and the drum 1 20 does not rotate, and then the hollow ring 13 is driven backward by the telescopic connecting rod 18, and the drum 1 20 does not move, so that the drum 2 21 rotates to drive the rear of the movable block 2 19, so that the hollow ring 13 is driven backward, and then the first fin 3 is driven to rotate backward along the outer surface of the connecting ring 2, and the angle of the first fin 3 can be adjusted by rotating the drum 1 20 or the drum 2 21, and then the angle between the fin tube and the air flow direction can be changed, and the heat exchange efficiency of the condenser tube 1 can be further adjusted;

[0045] Furthermore, the angle of each group of first fins 3 and the distance between each group of first fins 3 are changed, so that the first fins 3 and the sponge strips can be squeezed against each other, and the sponge strips cannot be separated, thereby not causing hidden dangers to the operation of the fan under the air condenser fin tube bundle structure.
