Title:
SERPENTINE HEAT EXCHANGER FOR AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2013/069358
Kind Code:
A1
Abstract:
Provided is a serpentine heat exchanger for an air conditioner, which effectively minimizes losses in heat-exchange performance due to condensation, and can be sufficiently used for a small-sized air conditioner. A serpentine heat exchanger for an air conditioner (10) is configured such that: a plurality of fins (12) is arranged parallel to each other at intervals of 0.6-5.0 mm in a direction (y direction) orthogonal to the direction (x direction) in which air flows as a heat-exchange fluid, and thereby constitutes a fin group (14); a plurality of such fin groups (14) is aligned in a direction (z direction) orthogonal to the x and y directions at a mutual distance of 2.0 mm or less, and thereby constitutes multistage fin groups (14); and a heat-exchanger pipe (16) is arranged in a serpentine configuration so as to sequentially pass through the fin group (14) at each stage.
