COLUMN-TYPE SECONDARY HEAT EXCHANGER OF A CONDENSING BOILER CAPABLE OF UNIFORMLY MAINTAINING THE TEMPERATURE OF ENDOTHERMIC FLUID

摘要

PURPOSE: A column-type secondary heat exchanger of a condensing boiler is provided to improve thermal efficiency by using a channel formed inside a main body hole as a heat insulating material. ;CONSTITUTION: A column-type secondary heat exchanger(30) of a condensing boiler comprises a column-shaped body(31), multiple exhaust pipes(40), a cover(70), and multiple dividers(50,60). The body has side plates(32), an inlet(34), and an outlet(33). A sealed chamber is formed inside the body by shielding both sides of the body using the side plates. The exhaust pipes are formed by passing through the chamber. Exhaust gas supplied from a first heat exchanger(20) passes through the exhaust pipes and is exhausted through an exhaust port connected to the cover. The dividers support the exhaust pipes.;COPYRIGHT KIPO 2011
