Japanese Patent JP6357480
Kind Code:
B2
Abstract:
The present invention relates to a fin-tube type heat exchanger, comprising: tubes through the inside of which a heat medium flows and which are arranged in parallel with a uniform distance therebetween, so that a combustion product can pass through space between the tubes; and heat transfer fins which are separately coupled to the outer surface of the tubes along the longitudinal direction thereof, so as to be parallel to the direction of flow of the combustion product, wherein inside the tubes a first turbulent flow-generating member is installed for creating turbulence in the flow of the heat medium, wherein the first turbulent flow-generating member comprises a flat plate part, arranged in the longitudinal direction of the tubes, for dividing the inner space of the tubes into two sides, and first guide pieces and second guide pieces which are protrudingly provided at a tilted angle and are separately and alternately provided along the longitudinal direction of both sides of the flat plate part.
