HEAT EXCHANGER OF GAS BOILER

摘要

PURPOSE: A heat exchanger of a gas boiler is provided to make heat much more exchanged within the heat exchanger by installing a heating water induction pipe inside the heat exchanger and disposing a thermal insulation member to a housing. CONSTITUTION: A heat exchanger of a gas boiler has sensible heat exchange pipes(30) with sensible heat fins(35) to exchange heat with heating water coming through a heating water induction pipe(25), through combustion heat of a burner. The heating water induction pipe is formed inside the heat exchanger, to improve heat exchange efficiency by increasing the heat transfer area of the heating water induction pipe. A thermal insulation member is installed to a housing(15) of the heat exchanger. Thus, heat is prevented from being radiated outside and more heat is absorbed to the heat exchanger.
