[0017] The present application will be further described in combination with the drawings.

[0018] As shown in the drawings, Figures 1 to 5 a heating fin, comprising a fin body 1, a plurality of fixing slots 11 are arranged on the fin body 1, the fixing slots 11 are rectangular slots, and can be arranged in an array along the length direction of the fin body 1, side pressing parts 15 are arranged on both sides of the fixing slots 11, the side pressing parts 15 are located on the long sides of the fixing slots 11, end pressing parts 14 are arranged at both ends of the fixing slots 11, the end pressing parts 14 are located on the short sides of the fixing slots 11, the end pressing parts 14 and the side pressing parts 15 are bent towards the same side of the fin body 1 and have a certain elasticity, the end pressing parts 14 and the side pressing parts 15 are formed by bending the fin body 1, and the fin body 1 is an integral structure, so that good heat conduction performance can be ensured. The fixing slots 11 are used for being inserted on a heating part 2, and the side pressing parts 15 and the end pressing parts 14 are used for being pressed on the heating part 2 to fix the fin body 1 and conduct heat.

[0019] The fin body 1 is made of thin aluminum plate, the aluminum plate has good heat conduction performance and a long service life, and has a certain elasticity.

[0020] In order to improve the pressing force on the heating part 2 and ensure reliable pressing, a plurality of first open slots 12 are arranged on the side pressing part 15, the first open slots 12 extend from the end of the side pressing part 15 to the fin body 1, the first open slots 12 divide the long side pressing part 15 into a plurality of independent side pressing plates, when one of the side pressing plates is deformed, the other side pressing plates are not affected, thereby ensuring reliable connection between the side pressing part 15 and the heating part 2, and thereby ensuring reliable heat conduction.

[0021] In order to improve the elastic force of the end pressing part 14, and avoid the connection between the end pressing part 14 and the side pressing part 15 from being torn due to stress, a second open groove 13 is arranged between the end pressing part 14 and the side pressing part 15, the second open groove 13 is arranged at 45°, the second open groove 13 can avoid stress concentration, prevent the fin body 1 from being torn, and ensure the strength of the fin body 1.

[0022] In order to fix the spacing between the fins when the fins are stacked, form good ventilation, and avoid deformation of the end of the fin body 1, positioning parts 16 are arranged at both ends of the fin body 1, the positioning parts 16 of the fin body 1 abut against the bottom of the fin body 1 above, thereby fixing the spacing between the heating fins. The positioning part 16 is a round edge, the round edge structure can ensure the height to be consistent, and can improve the strength and reduce the deformation of both ends of the fin body 1.

[0023] In order to protect the fin body 1 and avoid scratching other objects, rounded corners 19 are arranged on the four corners of the fin body 1.

[0024] The technical principles of the present application are described above in combination with specific embodiments. These descriptions are only for explaining the principles of the present application, and cannot be interpreted in any way as limiting the protection scope of the present application.
