摘要：PROBLEM TO BE SOLVED: To assemble an electric heating unit into a core part with good heat transmission even when a fastening member is eliminated, by connecting each hold plate to each bending top part of both adjacent corrugated fins, and assembling the electric heating unit and a spring member into the inside of each hold plate from an opening part thereof. SOLUTION: In a core part for a heat exchange, many flat tubes 6 are arranged in parallel to the flow direction of air for heating, to connect a wave- shaped corrugated fin 7 mutually between these flat tubes 6. Further, an electric heating unit 9 and a plate spring 11 are set up in lieu of the flat tube 6 in a plurality of locations. Here, a hold plate 10 of U-shaped section extended in the lengthwise direction of the flat tube 6 is arranged between each bending top part of the adjacent both corrugated fins 7. The electric heating unit 9 is inserted from an opening part 10b of the hold plate 10 and held in the inside. Further, transmission of heat from the electric heating unit 9 to the adjacent corrugated fins 7 can be improved.
