PROBLEM TO BE SOLVED: To realize a simple meandering pipe conduit structure in which a partition between adjacent paths becomes thin and strong, and to provide an inexpensive heat transfer device with meandering pipe which is superior in heat efficiency. SOLUTION: A pair confronted plates 11 and 12, the bent plate 21 of a waveform cross section shape which divides the plates into plural parallel paths 20a and 20b, and a pair of cover member 13 and 14 which are jointed to the bent plate 21 and form connection parts 20c and 20d between the parallel paths, are disposed. In the side walls 23a and 23b if a square groove in the bent plate 21, one side wall 23a is connected to the cover member 13 at one end side of the square groove and the other side wall 23b to the cover member 14 on the other end side of the square groove. Then, a meandering path 20 folded in opposite directions at the other end side of the square groove and one end side is formed. |
