ABSTRACT:
The present invention proposes a heat pipe heat exchanger comprising a hot gas flow duct, a cold gas flow duct and a plurality of heat pipes each with spiral fins around thereof that are installed horizontally a little slanted so that an end of each heat pipe in said hot gas flow duct becomes a little lower than the other end, and that said spiral fins are winding clockwise around some of the heat pipes and counter-clockwise around some other heat pipes. This device can prevent a bias flow of the steel balls at the so-called shot cleaning process performed for elimination of dust deposited on the heat pipes by arranging a layout of the two kinds of heat pipes, namely the heat pipes with clockwise winding fins around thereof and the heat pipes with counter-clockwise winding fins, and if required, can even control the flow of the steel balls so that they gather onto the area where more dust is deposited.
