フロータイプの熱交換器。 An inlet header pipe 1 into which the heat exchange fluid flows in and an outlet header pipe 2 through which the heat exchange fluid flows out are arranged in parallel at a distance of a predetermined length l, and a large number of flat pipes 5 are connected between the two header pipes 1 and 2. By inserting and fixing into each of these flat tubes 5 an inner fin having a wave-shaped cross section perpendicular to the axis with a predetermined pitch p, the flow path R in the flat tube 5 is formed into a plurality of small flow paths 12. The partitions are formed and each of these small channels 1
In the multi-flow type heat exchanger in which the fluid diameter of the heat exchange fluid is a predetermined value, the inner fin 20 has a waveform cut by shifting the waveform every predetermined length s with respect to the flow direction of the heat exchange fluid. Part h
A multi-flow type heat exchanger characterized in that the end face E of the next corrugated section is located between the preceding corrugated sections.
