摘要： PROBLEM TO BE SOLVED: To restrain pressure loss of a heat exchange fluid without impairing heat transmitting efficiency of a heat exchanger while achieving miniaturization of the heat exchanger and reduction of the cost by forming a flow passage on a surface of a metal thin plate such as a stainless steel plate with the usage of etching technique and by improving a shape of the flow passage.
SOLUTION: In the heat exchanger, a plurality of heat transmitting fins are provided on the metal thin plate with the usage of the etching technique, and the metal thin plates are stacked alternately, and the flow passage of the heat exchange fluid is formed between the confronting two metal thin plates. The heat transmitting fin is formed to have a cross section curved from the tip to the rear end, and a flow passage area of the fluid flowing through the heat transmitting fins is almost constant.
