<p>It is an object of the invention to provide a heat conduction pipe capable of removing soot deposited thereon without reducing a thermal conduction efficiency as a primary object of the heat conduction pipe, neither stopping cooling operation in the heat conduction pipe. This invention also provides a heat conduction pipe capable of minimizing reduction of the thermal conduction rate thereof for the soot by removing the soot while the soot deposits slightly on the inner surface of the heat conductive pipe. The heat conductive pipe comprises a base pipe 2 allowing a liquid to flow though an interior thereof; a plurality of axially extending grooves 4, formed parallel to a pipe axis in a row in a circumferential direction on an inner circumferential surface of the base pipe, having a cross section in a recess 3 shape with a prescribed depth; and a plurality of dividing walls 5 formed between the axially extending grooves 4 adjacent to each other having a prescribed thickness while a heat exchanger is assembled with said heat conduction pipes 1. <IMAGE></p> |
