In the installation method, as the cover plate 3 is provided with the semi-open heat dissipation groove 4, when the limit clamping seat is obliquely arranged, the heat dissipation groove 4 of the cover plate 3 can be clamped on the cover plate limit part 30, so that the cover plate 3 is limited on the limit clamping seat, the subsequent installation of the cover plate limit plate 33 and the bolt rod 34 is facilitated, the cover plate 3 can be fixed on the connecting bottom plate 19, and when the heat dissipation fins 5 are welded, the cover plate 3 does not displace; meanwhile, each radiating fin 5 is clamped and limited through an independent limiting clamping seat, so that the radiating fins 5 can be conveniently and independently welded, the position of each radiating fin 5 on the cover plate 3 can be accurately controlled, the welding quality is improved, and when the radiating fins 5 are welded, the radiating fins 5 and the cover plate 3 can be kept in an inclined state, so that waste materials during welding can be conveniently discharged. The utility model discloses a apron limiting plate 33 and shank of bolt 34 can wholly take out the welding and have the apron 3 of heat radiation fins 5, avoid touching heat radiation fins 5 after the welding, improve the security. The utility model rotates and resets the connecting bottom plate 19 through the motor 18 in the rotating device, so that the utility model can install the radiating fins 5 and the cover plate 3 in batches; because motor 18 and connecting bottom plate 19 are single-node connection, consequently set up location axle 21 in the outside of spacing seat 20, when through-hole 27 on the backup pad 26 of support frame 25 lets in on location axle 21 for the both sides of connecting bottom plate 19 all obtain supporting, improve connecting bottom plate 19 pivoted stability and reliability.
The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made on the basis of the present invention to solve the same technical problems and achieve the same technical effects are all covered by the protection scope of the present invention.
