S2: the positioning block 305 is manually pressed inward, and after the positioning block 305 moves below the positioning groove 306, the barrier 375 moves to a position close to the communication port 6 and the alignment rod 377 penetrates the communication port 6 under the elastic action of the compression spring 376.

S3: the heat pipe 5 is clamped by the clamping block 326, and the L-shaped placing plate 324 is pushed to move in the sliding groove 323 toward the transformer tank 4, so that the heat pipe 5 moves therewith and is precisely butted with the alignment branched chain 367.

S4: and welding the joints by using external welding equipment, after the welding is finished, manually adjusting the alignment mechanism 36 to move to the next designated position, resetting the clamping mechanism 32 and the alignment mechanism 36, and repeating the steps of S2 and S3 to finish the welding of the plurality of radiating pipes 5.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention; any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
