PURPOSE:To raise the thermal conductivity per unit length of a heat transfer pie and make the heat exchanger itself compact by providing, among the arrangement of a group of heat transfer pipes, heat radiation plates and heat transfer promoting rods. CONSTITUTION:In a casing a group of many heat transfer pipes 3 made of ceramics are arranged at right angle to the direction of a high temperature fluid flow, and each end of the pipe pierces a pipe plate section 10, and opens at the inlet section 4 of the air A for combustion and at the same time the other end of the pipe pierces the pipe plate section 10 and opens at the outlet section 5 of the air A for combustion, and the air A for combustion flows through respective heat transfer pipes A. And, in the group of heat transfer pipes in the casing 1, heat radiation plates 6 made of ceramics for promoting heat transfer are provided among the pipe arrangement along the direction of high temperature discharge gas HG and parallel to each heat transfer pipe 3. Further, among the pipe arrangement of the group of heat transfer pipes 3, heat transfer promoting rods 7 parallel to the pipes and in contact with the radiation plates 6 at an intermediate position between pipes are provided.
