PROBLEM TO BE SOLVED: To define each air path including an inlet and outlet in a space of a very thin thickness, i.e., a thickness of the height of a corrugated heat transfer sheet plus thickness of a pair of partitioning materials, at a low cost and obtain a heat exchange efficiency better than that of a cross-flow type by employing a counter flow type. SOLUTION: In this heat transfer element 31, a heat transfer sheet 61 having a corrugate section is supported by a frame 62, and a pair of partition members 63 crossing a corrugation are provided along ridges 61 m of the corrugation of the heat transfer sheet 61 on both faces. The partition members 63 define wind paths between the heat transfer sheet 61 and themselves, and an inlet and an outlet of the wind paths are defined before and behind the partition members 63 along a direction in which the ridges 61 m of the corrugation extend. A deformation preventing means 64 for preventing the corrugation of the heat transfer sheet from being deformed is provided, and a plurality of long-sized sheets 64a held in each valley and a pair of joint members 64b connecting both ends thereof constitute a grid-like integral member. The joint members 64b are stuck and fixed at the ridges 61 m of the corrugation of the heat transfer sheet 61. By this constitution, the heat transfer sheet is hardly deformed and air volume is assured and handling is easy. |
