Abstract
PURPOSE: To prevent fins of an air heater from partial and extraordinary overheating, by changing the pitches of fins or the heating surface area of fins of a heater of plate fin type, corresponding to the distribution of velocity of the air passing through the fins, and unifying the temperature on the surface of fins over the whole range.
CONSTITUTION: In an air heater provided with a heater 14 of plate fin type in front of a fan, the velocity of the air passing through the heater 14 is different between the front side and the side part of it. The speed is high in the front and is low in the side part of a heater. To provide uniform heating, pitches P1 of fins 14a of a heater 14 are made fixed, but the height of fins 14a are made such that it is high h2 in the part the air speed is low, and is low h1 in the part the air speed is high. Or conversely, the height of fins 14a is made fixed, but the pitches of fins are arranged such that they are made sparse P1 in the high speed part and are made dense P2 in the low speed part.
