Novel heat dissipation guide pipe

The utility model relates to a novel heat dissipation guide pipe which comprises a heat dissipation guide pipe body, two installation blocks are fixedly installed on the outer side of the heat dissipation guide pipe body, and heat dissipation fins are connected to the outer side of the heat dissipation guide pipe body and located above the installation blocks in a sleeved mode. A mounting mechanism of which one end is in contact with the radiating fins is arranged on one side, opposite to the mounting block, of the mounting block; and the mounting mechanism comprises mounting bins, threaded rods, threaded sliding blocks, clamping plates and clamping blocks, and the mounting bins are fixedly mounted on the opposite sides of the two mounting blocks. According to the novel heat dissipation guide pipe, through the arranged mounting mechanism, when the heat dissipation fins need to be dismounted for dust cleaning, threaded rods can be screwed, the threaded rods drive threaded sliding blocks, the threaded sliding b
