PURPOSE:To improve heat exchanging efficiency and prevent bonding agent from being forced out by a method wherein a plurality of first paths, having the apex thereof at the side of the center of a layered body and having V-shaped section in the peripheral direction of the layered body, and a plurality of second paths, extending radially from the center of the layered body between the first paths and having straight line shape section on the radial lines, are provided in the device. CONSTITUTION:The layered body 21 is formed into a column shape body as a whole and disc-shaped heat insulating plates and disc-shaped heat transfer plates are layered alternately through the bonding agent while the heat insulating plates located at the outermost layer of the layered body 21. The heat insulating plate 22 is provided with a plurality of holes and one type of them are the V-shape holes 23, arranged with equal spaces in the peripheral direction and whose apexes are located at the side of the center of the laminated body 21 or the insulating plate 22, while the other type of them are the holes 24 of straight line shape provided on the lines extending radially from the center of the insulating plate 22 and located between the V-shaped holes. Straight line shape holes 25 are provided respectively between both sides of the V-shape holes 23 and the first fluid path is formed by the holes 25 and the holes 24 to flow first fluid while the second fluid path is formed by the V-shaped holes 23 to flow the second fluid. |
