Abstract (en)
[origin: EP1906129A1] To simultaneously achieve both a heat transfer promoting effect and water drainability by guide fins in a fin tube heat exchanger. A fin tube heat exchanger (1) has heat transfer fins (2) disposed in an air flow and plural heat transfer tubes (3) that are inserted in the heat transfer fins (2) and disposed in a direction substantially orthogonal to a flow direction of the air flow. On the heat transfer fins (2), a set of guide fins (21a, 21 b) and a set of guide fins (21 c, 21 d) arranged straightly from upstream to downstream in the flow direction of the air flow are formed, by cutting and raising, on the heat transfer fin (2) surfaces on both sides of the heat transfer tubes (3). Straight lines (L 1 , L 2 ) that hypothetically interconnect the guide fins (21a, 21 b) and the guide fins (21 c, 21 d) slant with respect to the flow direction of the air flow so as to guide the air flow in the vicinities of the heat transfer tubes (3) to rear sides of the heat transfer tubes (3) in the flow direction of the air flow.
