LATENT HEAT RETURN STRUCTURE OF CONDENSATION HEAT EXCHANGER

摘要

PURPOSE: A latent heat recovery structure of a condensed heat exchanger is provided to improve efficiency of the heat exchange by guiding the combustion gas to the combustion chamber and a latent heat exchanger, and smoothly moving the combustion gas. CONSTITUTION: A latent heat recovery structure of a condensed heat exchanger(100) comprises a main body, a supply tube(20), a chamber(30), and a latent heat exchanger. The supplying tube is fixed inside the case(11). The main body comprises blocking caps(12,14) and a burner portion(13). The blocking caps and a burner portion are installed in the top and the combustion gas is exhausted downstream. The blocking cap of the lower part is coupled with the exhausting unit(16) The combustion gas passes through the supply tube to the horizontal direction, and flows to the outside. The upper and lower of the chamber which is expanded to the supplying tube is closed, the combustion gas is moved outside to the center. The latent heat exchanger is installed between the supplying tube and lower part of the blocking cap.
