PURPOSE: A heat exchange structure is provided to improve heat exchange efficiency by increasing the time of contact between intake air and exhaust air. CONSTITUTION: A heat exchange structure comprises an intake duct(11), an exhaust duct(12), a common air duct(10), and a counter flow heat exchange element(3). Intake air(1) is supplied from the exterior of the heat exchange structure through the intake duct. Exhaust air(2) is discharge from the interior of the heat exchange structure through the exhaust duct. The intake duct and the exhaust duct are united over a set range of length(L0) through the common air duct. The intake duct, the exhaust duct, and the common air duct are formed by bending a corrugated cardboard plate coated with a metal film into a cylindrical shape. The counter flow heat exchange element is installed inside the common air duct. |
