<p>A honeycomb structure (5) brazed with an outer casing (2) has a large corrugated foil (7) and a small corrugated foil (8) overlapped and wound alternately and formed like a cylinder by diffused junction. The large corrugated foil (7) and the small corrugated foil (8) has 20 mu m in thickness. The honeycomb structure (5) has 900 cells/square inches in cell density. The large corrugated foil has a wave height of 0.81mm and a pitch of 1.71mm. The small corrugated foil has a wave height of 0.05mm to 0.18mm and a pitch of 1.29mm to 1.39mm. Whereby the produced stress in each corrugated foil upon thermal expansion is reduced. <IMAGE></p> |
