[0002] Currently, Chinese utility model patent CN209945100U discloses a heat sink for a plate-fin heat exchanger. While this heat sink facilitates airflow, it presents several problems during use. These include difficulty in replacing the fins, the risk of damage and breakage from impacts during use or transportation, and the laborious and inconvenient process of replacing the fins due to the welded connection between the fins and the base. Furthermore, it requires regular cleaning when dust accumulates, as the narrow spacing between fins makes it difficult to reach them with tools and necessitates cleaning each fin individually, resulting in low practicality. To address these issues, we propose a detachable aluminum alloy heat sink. Utility Model Content

[0003] The purpose of this invention is to provide a detachable aluminum alloy heat sink, which solves the problems of existing heat sinks where it is inconvenient to replace the fins and clean the attached dust.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a detachable aluminum alloy heat sink, including a base, a slot on the front of the base, a fin inserted into the slot, a screw through one side of the base, a through hole for cooperating with the screw inside the fin, a fixing nut welded to the other side of the base, an L-shaped plate welded to the top of the base, a connecting plate inside the L-shaped plate, the connecting plate being located at the top of the fin, a brush plate installed at the bottom of the connecting plate, two limiting rods through the front of the connecting plate, and the back of the limiting rods welded to the inside of the L-shaped plate.

[0005] The above technical solution facilitates fin replacement, is simple and convenient to operate, reduces the maintenance burden and cost for personnel, and makes it easy to clean the attached dust. The process is efficient and comprehensive, ensuring the heat dissipation effect of the heat sink and making it highly practical.

[0006] The present invention is further configured such that a spring washer is slidably sleeved on the surface of the screw.

[0007] By adopting the above technical solution and setting the spring washer, the tightening effect of the screw after it is screwed in can be improved, which can play a role in preventing vibration and loosening.

[0008] The present invention is further configured such that a baffle is welded to the front side of the L-shaped plate.

[0009] By adopting the above technical solution, the connecting plate can be limited by the baffle, preventing it from falling off the surface of the limiting rod after it has moved to the bottom.

[0010] The present invention is further configured such that: a lead screw is welded to the top of the connecting plate, a sliding groove is provided on the top of the L-shaped plate, and the other end of the lead screw extends to the outside of the sliding groove and is threadedly connected to a locking nut.

[0011] By adopting the above technical solution, the connecting plate can be fixed by setting the lead screw, sliding groove and locking nut, preventing the connecting plate from moving on its own when shaken.

[0012] The present invention is further configured such that both the base and the fins are made of aluminum alloy.

[0013] Using the above technical solution, the base and fins are characterized by light weight, high specific strength, high specific stiffness and easy processing.

[0014] The present invention is further configured such that both the screw and the fixing nut are made of stainless steel.

[0015] Using the above technical solution, the screw and fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model allows for easy replacement of fins when they are damaged. First, a tool is used to grasp the screw and rotate it counterclockwise. As the screw rotates counterclockwise, it moves outward from the fixing nut and separates from it. Once separated, the screw is pulled out, releasing the fin's fixation. The damaged fin is then removed from the slot, and a new one is inserted. Finally, the screw is reinserted and tightened. This method is simple, convenient, and reduces the repair burden and costs for personnel.

[0018] 2. This utility model first loosens the locking nut, which releases the fixing of the connecting plate. Then, the person grabs the lead screw or directly grabs the connecting plate and pulls it forward. When the connecting plate is pulled forward, it will drive the brush plate to move forward. When the brush plate moves forward, it will contact the fins and wipe their surface, which can easily clean the attached dust. The process is efficient and comprehensive, ensuring the heat dissipation effect of the heat sink and making it highly practical. Attached Figure Description
