PURPOSE:To improve fins and tube elements of a lamination type heat exchanger, enhance the efficiency of heat exchange, and reduce its size. CONSTITUTION:The width of fins FW in the ventilating direction, the plate thickness of fins FT, fin pitches FP, the height of fins FH and the thickness of tube elements TW are set in the following relation, 50mm<=FW<=65mm, 0.06mm<=FT<=0.10mm, 2.5mm<=FP<=3.6mm, 7.0mm<=FH<=9.0mm, 2.0 mm<=TW<=2.7mm. These relational expressions make it possible to provide fin shape which enables heat exchange efficiency and ventilation resistance to be properly balanced and the optimum thickness of tube elements as well.
