Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and in particular relates to a conveniently retractable heat dissipation fin for a heat exchanger. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Common heat exchangers have various forms, among which the parallel flow heat exchanger is the most widely used due to its compact structure and small size. Common parallel flow heat exchangers mainly include a pair of parallel and separate manifolds, a number of flat tubes whose ends are connected to the inner cavities of the two manifolds and are parallel to each other, fins arranged between adjacent flat tubes, and two side plates fixedly connected to the outer flat tubes through the fins. The manifold is provided with a number of holes for connecting the flat tubes. After assembly, the entire heat exchanger has a flat plate-like structure. During operation, the refrigerant flows along the flat tubes between the manifolds in the designed direction, and while flowing, it exchanges heat with the air blowing through the fins.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the embodiments.

[0026] See also Figure 1-5 The utility model provides a conveniently retractable heat dissipation fin for a heat exchanger, comprising a base plate 1 and a frame 2. The frame 2 is fixed to the top side wall of the base plate 1. A bearing plate 3 is arranged inside the frame 2. A heat dissipation fin body 4 is fixed to the side wall of one side of the bearing plate 3. A heat exchange tube 5 is arranged on one side of the heat dissipation fin body 4. A water inlet pipe 6 is fixed to one end of the heat exchange tube 5, and a water outlet pipe 7 is fixed to the other end of the heat exchange tube 5. An adjustment component 8 adapted to the frame 2 is arranged on one side of the bearing plate 3.

[0027] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the adjustment component 8 includes multiple mounting sleeves 81, and the multiple mounting sleeves 81 are symmetrically distributed and fixed on the side wall of one side of the bearing plate 3. The side wall of one side of the mounting sleeve 81 is threadedly connected with a screw 82, and one end of the screw 82 is rotatably connected to the inner side wall of the frame 2. The inner side wall of the frame 2 is fixed with multiple symmetrically distributed connecting rings a83, the screw 82 is located inside the connecting ring a83, and a spring a84 is fixed to the side wall of one side of the connecting ring a83, and the spring a84 is located outside the screw 82. A connecting ring b85 is fixed to the other end of the spring a84, and a side wall of one side of the connecting ring b85 is in contact with a side wall of one side of the mounting sleeve 81. Through the setting of the adjustment component 8, the shock-absorbing hardness and softness between the bearing plate 3 and the frame 2 can be adjusted according to specific actual needs, and the device can effectively improve the buffering and protection of the heat dissipation fin body 4 and the heat dissipation pipe during transfer, which can extend the service life of the device, facilitate the adjustment of the spacing position between the heat dissipation fin body 4 and the heat dissipation pipe, and has the function of flexible and convenient adjustment.

[0028] Further as Figure 2 As shown, it is worth mentioning that the diameter values ​​of the connecting ring a83 and the connecting ring b85 are consistent, and the central axes of the connecting ring a83 and the connecting ring b85 are collinear with the central axis of the screw 82. The size setting of the connecting ring a83 and the connecting ring b85 ensures that the spring a84 can be in a good compression and rebound effect.

[0029] This solution has the following working process: when the device needs to be used, move the device to the designated working position to ensure that the water inlet pipe 6 and the water outlet pipe 7 are both in a connected water supply state, thereby ensuring that the heat exchange tube 5 body is in a circulating water supply state, and cooperate with the heat dissipation effect of the heat dissipation fin body 4 to cool and dissipate the water source in the heat exchange tube 5 body. When the buffer strength between the heat dissipation fin body 4 and the frame 2 needs to be adjusted, the pull ring 124 is pulled to make the limit rod 122 move synchronously, driving the mounting ring 125 to move synchronously. At this time, the spring b126 is in a stretched state until the limit rod 122 and the limit sleeve 123 are in a separated state, thereby releasing the limiting effect on the cover plate 11, and the corresponding type of screwdriver or other tools can be used to drive the screw rod 82 to rotate synchronously, and the threaded transmission effect between the screw rod 82 and the mounting sleeve 81 is used to cause the bearing plate 3 to move closer to the frame 2 after being subjected to force. At this time, the spring a84 is in a compressed state, thereby achieving the purpose of adjusting the buffering hardness of the bearing plate 3.

[0030] According to the above working process, it can be known that: through the setting of the adjustment component 8, the shock-absorbing hardness and softness between the carrier plate 3 and the frame 2 can be adjusted according to the specific actual needs, and the buffering protection of the heat dissipation fin body 4 and the heat dissipation tube during transfer of the device can be effectively improved, and the service life of the device can be extended, and it is convenient to adjust the spacing position between the heat dissipation fin body 4 and the heat dissipation tube, and it has the function of flexible and convenient adjustment.
