<p>PROBLEM TO BE SOLVED: To prevent lowering of heat exchange performance caused by heat exchange between refrigerants different in temperatures by thermal conduction through corrugated fins in a portion in which respective flat parts of a plurality of serpentine tubes adjoin each other, and to make a heat exchanger exhibit its original heat exchange performance.SOLUTION: In a portion in which flat parts 12 contributing to the heat transfer of a plurality of serpentine tubes adjoin each other via corrugated fins 3, the flat parts 12 connected to respective inlet shunts 4 of a plurality of the serpentine tubes, that is, the flat parts 12 nearest an upstream-side end are arranged so as to adjoin each other via the corrugated fins 3, or the flat parts 12 connected to respective outlet shunts 5 of a plurality of the serpentine tubes, that is, the flat parts 12 nearest a downstream-side end are arranged so as to adjoin each other via the corrugated fins 3.</p> |
