Title:
HEAT EXCHANGER COMPRISING FINS AND TUBE
Document Type and Number:
WIPO Patent Application WO/2013/172577
Kind Code:
A1
Abstract:
The present invention relates to a heat exchanger comprising fins and a tube, comprising: a tube, inside of which heating water flows; and multiple fins, the interior of each of which has a tube insertion hole for the insertion of the tube, and each of which has a protruding rib along the circumference of the tube insertion hole in the lengthwise direction of the tube so as to enable each fin to be coupled to the outer surface of the tube at a predetermined interval, thus transferring the combustion heat of a burner to the heating water flowing inside the tube. A heat insulation chamber, which is a space between the lower end of the tube and the rib, is formed along the circumference of the lower end of the tube located at the side at which the combustion gas of the burner is fed in, so as to prevent the combustion gas from directly contacting the lower end of the tube.
