LAMINATED STRUCTURE TYPE HEAT EXCHANGER

PURPOSE:To prevent the heat transfer performance from lowering by a structure wherein rising parts and falling parts are alternately provided at certain fixed pitches in fins and the fins are fixed at positions so that the relative position between the fins adjacent to each other is staggered by half a pitch by means of pitch adjusting members. CONSTITUTION:Rising parts and falling parts are alternately provided at certain fixed pitches in respective fins 5 and 7. The fins 5 and 7 are fixed at positions so that the relative position between adjacent fins 5 and 7 is staggered by half a pitch by means of pitch adjusting members 6 and 8. Thus, because the positions of the fins adjacent to each other before and behind are surely configurated with staggering by half a pitch, the heat transfer performances of the fins 5 and 7 are prevented from lowering.
