Abstract
Description
The present invention relates to a heat transfer fin of a heat exchanger for a boiler which allows a speed of an exhaust gas flowing between a fin and a pin to flow constantly or rapidly in a fin type heat exchanger. More specifically, To a heat transfer fin of a heat exchanger for a boiler which collects exhaust gas around pipes of a boiler.
Generally, a condensing gas boiler is a boiler designed to reduce heat loss by absorbing discarded heat back into the boiler and recycling it, and is widely used because it has excellent thermal efficiency and remarkably reduces fuel cost .

However, in the conventional heat exchanger for a boiler having such a structure, the cross sectional area of the exhaust gas passages through which the exhaust gas passes is the same, that is, the cross sectional area of the exhaust gas passages formed by the flanges of the through holes is the same, The temperature of the exhaust gas is lowered and the speed of the exhaust gas is lowered. As a result, the heat exchange efficiency is lowered.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and it is an object of the present invention to provide a fin type heat exchanger in which the structure of the fin is improved so that the speed of the exhaust gas flowing between the pin and the fin constantly or rapidly flows, So that the heat exchange efficiency can be improved by collecting the gas.
According to an aspect of the present invention for achieving the above object, there is provided a heat transfer fin of a heat exchanger for a boiler in which a plurality of through holes through which a heat absorbing tube passes are formed and flanges are respectively formed in the through holes, There is provided a heat transfer fin of a heat exchanger for a boiler, characterized in that a through-hole having a flange is formed so that the cross-sectional area of the gas passage is gradually narrowed.
The heat transfer fin of the heat exchanger for a boiler according to the present invention is formed such that the cross sectional area of the exhaust gas passage through which the exhaust gas passes is gradually narrowed along the direction in which the exhaust gas flows so as to collect the exhaust gas around the pipe of the heat exchanger, An effect of improving the efficiency can be expected.
