Description

Technical Field

[0001] This application relates to the field of radiators, and more specifically, to a radiator fin and its heat exchange device. Background Technology

[0002] In heat exchangers and heaters, fins are key components for improving heat exchange efficiency. Traditional fin structures are mostly plate-type fins, which, while simple in structure, have a relatively small surface area, limiting their heat exchange efficiency. Generally, curved fins introduce bending or curvature on the windward side, increasing airflow resistance and causing pressure loss, requiring a more powerful fan or pump to maintain the required gas flow.

[0003] The flat surface of plate fins causes air to form a thicker boundary layer along the surface, which increases thermal resistance and reduces heat transfer efficiency. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide a heat sink fin, including:

[0006] Main area;

[0007] The windward zone is located on one side of the main area;

[0008] The leeward area is located on the other side of the main area;

[0009] Heat exchange holes are arranged in both the main body area and the leeward area, and connecting pipes are provided on the heat exchange holes. The connecting pipes are formed by stretching the fins themselves.

[0010] The main body area has wavy fins, the windward area is wavy with multiple crests and troughs, and the leeward area has a plate-shaped structure that is smoothly connected to the main body area.

[0011] This application improves heat exchange efficiency by altering the shape of the windward zone, thereby promoting turbulence as airflow passes between the windward and main body zones. Conversely, by altering the shape of the leeward zone, the surface area is reduced as airflow leaves the fins, thus lowering airflow resistance.

[0012] Furthermore, the heat exchange vias are arranged in an array between adjacent rows and columns.

[0013] Furthermore, the windward area and the main body area are arranged vertically.

[0014] Furthermore, the top of the connecting pipe is arranged in a flared shape.

[0015] Furthermore, the heat exchange device includes:

[0016] Box;

[0017] The outer casing is located on one side of the box.

[0018] The water inlet pipe is located on the casing.

[0019] The water outlet pipe is located on the casing;

[0020] The fins are arranged inside the box. The shell contains several first pipes and second pipes. One end of the first pipe is connected to several connecting pipes, and the other end is connected to the water inlet pipe. One end of the second pipe is connected to several connecting pipes, and the other end is connected to the water outlet pipe.

[0021] Furthermore, the inlet pipe and outlet pipe are both located on the same side of the casing and are arranged parallel to each other.

[0022] Furthermore, the shell and the housing are connected by bolts.

[0023] Furthermore, the housing includes:

[0024] The first connecting part is symmetrically located at both ends of the box body;

[0025] The second connection part is provided on the first connection part near the water inlet pipe;

[0026] The first connecting part and the second connecting part are connected by welding. The first connecting part has an "L" shaped structure.

[0027] The beneficial effects of this application are as follows: the surface of the main body area has a wave-shaped structure with multiple continuous crests and troughs, which can increase the surface area, promote turbulence, and improve the heat exchange rate; the windward area is located on the airflow inlet side, and its surface has a wave-shaped structure, which is vertically distributed in the main body area of ​​the fin plate, promoting turbulence when it initially contacts the airflow; the leeward area is located on the airflow outlet side, and its surface has a plate-shaped structure, which reduces the surface area in contact with the airflow and reduces the resistance when the airflow leaves.

The leeward region 4 has a plate-like structure and is smoothly connected to the main body region 2. This application improves heat exchange efficiency by changing the shape of the airflow-facing region 3, which promotes turbulence when airflow passes through the airflow-facing region 3 and the main body region 2. By changing the shape of the leeward region 4, the surface area is reduced when airflow leaves the fin, thus reducing airflow resistance.

The windward area 3 is located on the side where the airflow enters, and its surface has a wave-shaped structure. It is vertically distributed on the main body area 2 of the finned plate and promotes turbulence when it initially contacts the airflow. The leeward area 4 is located on the side where the airflow leaves, and its surface has a plate-shaped structure, which reduces the surface area in contact with the airflow and reduces the resistance when the airflow leaves.
