Abstract
A heat exchanger unit includes tube units arranged within a duct unit for heat exchange with combustion gas supplied from a furnace of a thermal power plant, and heat exchanger fins longitudinally formed on outer peripheral surfaces of the tube units and having different thickness and sizes while heat exchange with the combustion gas is performed through the heat exchanger fin.
Claims20
A heat exchanger unit comprising:
- tube units arranged within a duct unit configured for heat exchange with combustion gas supplied from a furnace of a thermal power plant;
- and
- heat exchanger fins formed on outer peripheral surfaces of the tube units, wherein the heat exchanger fins have a width side, a length side and a thickness side, and the length side is longer than the width side and the thickness side, and a direction of the length side of the heat exchanger fins traverses a direction of a longitudinal length of the tube units, the heat exchanger fins having different thickness and sizes, configured to perform heat exchange with the combustion gas.
