HEAT EXCHANGER FOR AIR CONDITIONERS

Document Type and Number:

WIPO Patent Application WO/1998/019126

Kind Code:

A1

Abstract:

A heat exchanger used for an air conditioner, wherein a plurality of fins (10) are provided in parallel, through which a plurality of windward heat exchanger tubes (13) and a plurality of leeward heat exchanger tubes (14) are passed. The heat exchanger tubes (13, 14) are provided so as to extend in substantially the same direction in a generally staggered manner. In the intermediate portions of the fins which are located between the windward heat exchanger tubes (13) and the leeward heat exchanger tubes (14), cuts (15) are provided. The cuts (15) are arranged in the same direction as the heat exchanger tubes (13, 14) and extend in the direction which crosses the direction X in which the cuts are arranged. Owing to this construction, the unnecessary transfer of heat via the fins is prevented, and, moreover, a sufficient level of rigidity of the fins can be secured.
