PURPOSE: To obtain a heat exchanger module capable of substantially reducing flow resistance. CONSTITUTION: A heat exchanger module 1 is formed by laminating thin plate elements each having an opening portion 3, and combining the laminated individual elements. Thin plates or a group thereof of the laminated thin plate elements are disposed by being rotated around a common axis by an angleαof 0 to 30 deg. with respect to the thin plate elements or the group assembled before it, and the opening portion 3 forms a helical passage 4. |
