Title:
FIN STRUCTURE FOR UNITARY TYPE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/1999/030098
Kind Code:
A1
Abstract:
A fin structure for unitary type heat exchangers, having a high heat isolation rate between two heat exchangers. In a duplex unitary type heat exchanger composed of a plurality of heat exchangers, to which common fins alternately layered together with tubes are provided, there is formed on a pole section at a predetermined position of the fins a connection for connecting first fins arranged between tubes on one of the heat exchangers to second fins arranged between tubes on the other of the heat exchangers, the first fins and the second fins constituting the fins. Because the first fins and the second fins are in a state, in which they are separate from each other, in a portion except at the connection, the heat isolation rate for the first fins and the second fins can be enhanced.
