[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator, radiator and reboiler, etc., and is widely used. Heat exchanger is usually set in a container with a metal sheet with strong thermal conductivity to speed up the efficiency of heat conduction and increase the heat exchange surface area of ​​the heat exchanger. The metal sheet with this function is called fin.

[0003] A heat exchanger fin in the prior art is prone to damage and deformation during use, which affects the normal use and normal heat dissipation of the heat exchanger, and affects the heat dissipation efficiency of the heat exchanger. When the fin is replaced due to damage, it is usually replaced as a whole, which is costly. It is not possible to replace the damaged fin body alone, which has poor practicality. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when a damaged fin is replaced, it is usually replaced as a whole, which is costly and cannot replace a damaged fin body alone, and proposes a heat exchanger heat dissipation fin.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heat exchanger cooling fin, including a frame, in which a plurality of cooling fin bodies are inserted, a first slot matching the plurality of cooling fin bodies is opened at the top of the frame, a second slot matching the plurality of cooling fin bodies is opened on the inner bottom wall of the frame, a clamping plate is provided on one side of each second slot in the frame, a driving structure for driving the plurality of clamping plates to move synchronously is provided in the frame, and connection ports are opened at both ends of the frame and in the cooling fin bodies.

[0006] Preferably, the driving structure comprises an inner cavity opened in the frame, a screw is arranged in the inner cavity, a plurality of moving blocks are threadedly connected to the outer wall of the screw, and one end of each of the moving blocks is respectively fixed to each clamping plate.

[0007] Preferably, a slot is formed at one end of the frame, a connecting column is fixed at one end of the screw rod, an end of the connecting column away from the screw rod passes through the frame and is fixed with a rotating plate, and the rotating plate is arranged in the slot.

[0008] Preferably, the other end of the screw is rotatably connected to the inner cavity, and a clamping groove matching the clamping plate is provided at one end of each second slot in the frame, and both ends of the clamping groove are respectively connected to the second slot and the inner cavity.

[0009] Preferably, a first opening is provided at one end of the frame on one side of the first slot, a first baffle is slidably connected in the first opening, and the first baffle is fixed to the frame by a first bolt.

[0010] Preferably, a second opening is provided at one end of the frame on one side of the second slot, a second baffle is slidably connected in the second opening, and the second baffle is fixed to the frame by a second bolt.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] When the heat dissipation body is damaged, the user can unscrew the first bolt and the second bolt, slide out the first baffle and the second baffle, and then rotate the rotating plate to drive the connecting column to rotate, thereby driving the screw to rotate, so that the multiple moving blocks can move laterally under the limit of the inner cavity matching them, thereby driving the multiple clamping plates to move, so that they no longer clamp and fix the bottom end of the heat dissipation fin body. At this time, the user can pull out and replace the damaged heat dissipation fin body separately according to the damaged heat dissipation fin body, without replacing the whole body, thus reducing the replacement cost and making it more practical. Moreover, through the movement of the clamping plate, the heat dissipation fin body plugged in the first slot and the second slot can be clamped and fixed to avoid shaking, and the stability is stronger.

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment 1, as Figure 1-4 As shown, the utility model provides a heat exchanger cooling fin, including a frame 1, a plurality of cooling fin bodies 2 are inserted in the frame 1, a first slot 3 matching the plurality of cooling fin bodies 2 is opened at the top of the frame 1, a second slot 4 matching the plurality of cooling fin bodies 2 is opened on the inner bottom wall of the frame 1, a clamping plate 12 is provided on one side of each second slot 4 in the frame 1, a driving structure 14 for driving the plurality of clamping plates 12 to move synchronously is provided in the frame 1, and connection ports 11 are opened at both ends of the frame 1 and in the cooling fin bodies 2.

[0021] The effect achieved by the entire embodiment 1 is that, through the setting of the first slot 3 and the second slot 4, the device as a whole does not need to be disassembled, and the heat sink fin body 2 can be inserted at will for installation. Through the setting of the driving structure 14, multiple clamps 12 can be driven to move, and the heat sink fin body 2 inserted in the first slot 3 and the second slot 4 can be clamped and fixed to avoid shaking and displacement, and the stability is stronger. Moreover, through the reverse movement of the clamp 12, the heat sink fin body 2 is no longer clamped and fixed. At this time, the damaged heat sink fin body 2 can be taken out and replaced separately, which is more practical.

[0023] The effect achieved by the entire embodiment 2 is that when the heat dissipation fin body 2 is damaged, the user unscrews the first bolt 7 and the second bolt 10, and slides out the first baffle 6 and the second baffle 9. At this time, the user rotates the rotating plate 16 to drive the connecting column 15 to rotate, thereby driving the screw 1402 to rotate, so that the multiple moving blocks 1403 move laterally under the limit of the inner cavity 1401 matching them, thereby driving the multiple clamping plates 12 to move, so that they no longer clamp and fix the bottom end of the heat dissipation fin body 2. At this time, the user can pull out and replace the damaged heat dissipation fin body 2 separately without replacing it as a whole, thereby reducing the cost of replacement and making it more practical. Moreover, through the movement of the clamping plate 12, the heat dissipation fin body 2 plugged in the first slot 3 and the second slot 4 can be clamped and fixed to avoid shaking, and the stability is stronger.

The user rotates the rotating plate 16 to drive the connecting column 15 to rotate, thereby driving the screw 1402 to rotate, so that the multiple moving blocks 1403 move laterally under the limit of the inner cavity 1401 matched therewith, thereby driving the multiple clamping plates 12 to move, so that the bottom end of the heat dissipation fin body 2 is clamped and fixed, thereby achieving the effect of installing the heat dissipation fin body 2. When one of the heat dissipation fin bodies 2 is damaged, the user unscrews the first bolt 7 and the second bolt 10, and slides out the first baffle 6 and the second baffle 9. At this time, the user rotates the rotating plate 16 again to drive the connecting column 15 to rotate, thereby driving the screw 1402 to rotate, so that the multiple moving blocks 1403 move laterally under the limit of the inner cavity 1401 matched therewith, thereby driving the multiple clamping plates 12 to move, so that they no longer clamp and fix the bottom end of the heat dissipation fin body 2. At this time, the user can pull out the damaged heat dissipation fin body 2 separately for replacement.
