PURPOSE:To permit to form a heat exchanging body having various sizes, shapes and performances by a method wherein the plate type body, made of ceramics, and the heat exchanging element, consisting of a tube, are connected to the through-hole of a frame body through an elastic body of rubber. CONSTITUTION:In the heat exchanging element 11, a plurality of tubes 21, made of ceramics, is penetrated through the plate-like body or a fin 31, made of ceramics, and both of them are fixed mutually by each other. According to this method, heat conductivity is large and high fin efficiency is obtained while the dew-point corrosion by sulfuric acid may be avoided. The frame body 41 is bored with the through-holes 45 at the same position as the tube 21 and a gap between the frame body 41 and the outer diameter of the end 22 of tube is fitted with the elastic body 51 of rubber. Further, the tube end 22 of a different heat exchanging element 11 is fitted into the elastic body 51 and, thus, a plurality of heat exchanging elements 11 are connected with each other. Accordingly, the outflow leakage of fluid may be prevented and shock vibration may be absorbed. On the other hand, thermal deformation may be absorbed even when a multitude of elements 11 is connected and the assembling work may be facilitated.
