Since the first driven gear 63 meshes with the second driven gear 64, the first driven gear 63 drives the second driven gear 64 to rotate. Since both the first driven gear 63 and the second driven gear 64 are detachably connected to the corresponding heat pipe assembly 11, the heat pipe assembly 11 rotates relative to the corresponding seamless steel pipe 2. Since the first heat pipe 12 and the second heat pipe 18 connected end to end are installed sequentially on the same seamless steel pipe 2, it is easier to install than a single installation pipe. Since the connecting limiting post 17 of the first heat pipe 12 and the radial elongated hole 15 of the second heat pipe 18 are slidably connected along the length direction of the radial elongated hole 15, the rotation of the first heat pipe 12 during rotation drives the rotation of the second heat pipe 18.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
