The patent document includes an upper cover plate, a lower cover plate, and an aluminum plate. The aluminum plate is shaped like a parallelogram, with the short side and long side of the aluminum plate forming an angle a between 30 and 75 degrees. The aluminum plate is perpendicular to the horizontal plane, with the short side parallel to the horizontal plane. The upper and lower cover plates are fixed to the aluminum plate on either side of the short side. A right-angled trapezoidal reinforcement block is fixed to the right side of the aluminum plate, with the inclined surface of the right-angled trapezoidal reinforcement block aligned with the right side of the aluminum plate. A right-angled triangle reinforcement block is fixed to the right side of the aluminum plate, with the inclined surface of the right-angled triangle reinforcement block also aligned with the right side of the aluminum plate. The invention features a simple and reasonable structure, low height, good heat exchange performance, and high drainage efficiency. It significantly reduces the height of the unit housing, lowers costs, reduces space occupation, expands the scope of application, and saves energy.

[0003] This patent cannot achieve rapid connection and assembly of multiple aluminum fins. The single installation method is more laborious and it is difficult to ensure the installation stability and structural strength of each aluminum fin. Its practicality is poor. For this reason, we propose an aluminum fin for the coil in a combined air-conditioning unit to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide an aluminum fin for a coil in a combined air-conditioning unit to solve the problems raised in the above-mentioned background technology.

[0006] The splicing mechanism includes two connecting blocks, and the opposite sides of the connecting blocks are fixedly connected by a secondary aluminum plate. The internal rotation of the connecting block is connected to two circular rotating blocks, and the two circular rotating blocks are fixedly connected to the opposite sides with a connecting rod. One end of the connecting rod passes through the outside of the connecting block and is fixedly connected to an insert block.

[0007] Furthermore, the aluminum fin body includes two sealing plates, and opposite sides of the sealing plates are fixedly connected by a main aluminum plate.

[0008] Furthermore, the interior of the sealing plate is symmetrically provided with a connecting chamber, and both sides of the sealing plate are provided with insertion openings that communicate with the connecting chamber, and the insertion openings are adapted to the insert blocks.

[0009] Furthermore, the cross-section of the plug is rectangular and its two short sides are arc-shaped, and the cross-section of the connecting chamber is circular and its diameter is slightly larger than the long side of the cross-section of the plug.

[0010] Furthermore, a reinforcement plug plate is symmetrically installed on one side of the plug block close to the connection block, and a reinforcement slot communicating with the connection chamber is opened at a position of the sealing plate corresponding to the reinforcement plug plate.

[0011] Furthermore, a guide rotating plate is fixedly connected to the outer side of the circular rotating block, and an arc-shaped groove with a central angle of ninety degrees is opened at a position of the connecting block corresponding to the guide rotating plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] When the utility model assembles the aluminum fin body and the splicing mechanism, under the connection of the circular rotating block, the connecting rod is first rotated by guiding the rotating plate and the limit of the arc groove, so that the insert block is rotated to a horizontal position. At this time, it can be inserted into the connecting chamber through the insertion opening on the outside of the sealing plate, and then the connecting rod is rotated ninety degrees, and the aluminum fin body and the splicing mechanism are pulled outward. The reinforcing insert plate will be inserted into the reinforcing slot to form a connection and fixation. The above operations can be performed in sequence to form a combination of multiple aluminum fin bodies and multiple splicing mechanisms. The aluminum fins used for the coil in the combined air-conditioning unit have a reasonable structural design, can realize the rapid splicing and combination of multiple aluminum fins, and ensure the heat exchange effect. At the same time, the combined design is convenient for installation, and has a high overall structural strength after installation. It is highly practical and can fully meet the use needs of the coil in the air-conditioning unit. BRIEF DESCRIPTION OF THE DRAWINGS
