    Abstract: PURPOSE:To make a thin interface layer generated on the surface of the fins to get a higher thermal transfer by a method wherein fins having gate-shaped cut and raised slotted pieces formed by bending the front edges at the gas flow inlet end and the thermal medium pipe passing through the fins are provided. CONSTITUTION:A heat exchanging operation is performed between a gas flow B and a thermal medium flowing in the thermal medium pipe 2. The gas flow B flowing along the surfaces of the small piece fins 3 is abutted against the gate-shaped cut and raised slotted pieces 4 at the front edges of the fins to increase a distribution of pressure, so that the higher thermal conduction is increased between the surfaces of the cut and raised slotted pieces 4 and the gas flow B. Further, the gas flow B abutted against the cut and raised slotted pieces 4 is passed through the area enclosed by the pieces 4 and the fins 3, so that the flow speed of the gas is accelerated, the interface layer generated at the surfaces of the fins 3 becomes thin. When the gas flow B is struck against the pieces 4, the gas flow B generates eddy current at the pieces 4 to promote the disturbance and the interface layer generated at the surfaces of the fins 3 becomes more thin and thereby a higher thermal transfer is provided between the fins 3 and the gas flow B. Further, since the fins 3 are divided into each of the rows in a direction of the gas flow B, the development of the interface layer is interrupted and the performance of the thermal transfer is further promoted.

    Abstract: PURPOSE:To increase a moistening amount, in a moistening device used for prevention of drying of indoor air. CONSTITUTION:A moistening device comprises a moistening element 1: and a water feed tank 2 to feed water to the moistening element 1. Further, the moistening deice is provided with an infrared ray heater 6 to irradiate and heat the moistening element 1 and promote vaporization of water held in the moistening element, and a reflection plate 7a.
