Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Refer to the instruction manual Figure 1-5 The utility model provides an H-shaped fin tube, comprising a fin tube 1 installed on a boiler, wherein a plurality of heat dissipation components for enhancing heat dissipation performance are installed on the outside of the fin tube 1, and a shaping component for enhancing stability and preventing deformation is provided between two adjacent heat dissipation components;

[0025] In order to facilitate the support and fixation of the fin member 4 and ensure the structural stability of the fin member 4, as shown in FIG. Figure 1 、2 As shown in Figures 4 and 5, the shaping component includes two protective frames 2, which are respectively mounted on the top and bottom of the fin tube 1, and a plurality of air holes 3 are opened on the outside of the protective frame 2.

[0026] Specifically, the limiting support of the protective frame 2 can effectively improve the structural stability of the fin member 4 and avoid distortion of the fin member 4 caused by collision and impact, thereby ensuring the service life and performance of the fin member 4.

[0027] In order to facilitate heat dissipation and cooling of the finned tube 1, Figure 1-3 As shown, each group of heat dissipation components includes two upper and lower corresponding fin members 4, and the two fin members 4 are respectively arranged at the top and bottom of the fin tube 1, and the two fin members 4 and the fin tube 1 are combined into an H shape; the protective frame member 2 is arranged between the two fin members 4 on the two adjacent groups of heat dissipation components. Through the two fin members 4 distributed in the H shape, the fin tube 1 can absorb and dissipate heat in multiple directions, thereby improving the heat dissipation performance and heat dissipation efficiency of the fin tube 1.

[0028] In order to facilitate the installation and fixation of the protection frame 2 and ensure the stability of the protection frame 2, as shown in FIG. Figure 1 、 2 As shown in Figures 4 and 5, a fastening bolt 5 is provided on the side of the protection frame 2 away from the fin tube 1.
