The utility model belongs to the technical field of collecting pipes, and particularly relates to a collecting
pipe with a cooling fin mounting and dismounting structure, which comprises a cooling fin body and two collecting
pipe bodies, the cooling fin body is arranged between the two collecting
pipe bodies, two ends of the cooling fin body are provided with
butt joint blocks, and the
butt joint blocks are connected with the collecting pipe bodies. A fixing block is connected to the side wall, close to the cooling fin body, of the collecting pipe body, a through hole is formed in the side wall of the fixing block in a penetrating mode, a mounting plate is connected to the side wall, away from the fixing block, of the collecting pipe body, and a protruding block is mounted at the top end of the fixing block; according to the utility model, the inconvenience of
welding and fixing the radiating fin body and the collecting pipe body in the later maintenance process is reduced, and through the matching between the fixing pin and the telescopic spring, the radiating fin body can be conveniently disconnected from the fixing block and rematched and mounted through the
butt joint block, so that the radiating fin body is convenient to
mount and dismount, and the service life of the radiating fin body is prolonged. And the convenience of later maintenance is improved.
