Abstract:
A parallel integrated heat exchanger having a plurality of heat exchangers, each provided with a heat exchanging unit constituted with fins and a plurality of tubes laminated via said fins and tanks communicating with said plurality of tubes, with adjacent heat exchangers joined by having said heat exchanging units thereof facing opposite each other and fins of said adjacent heat exchangers formed as an integrated common member, whereinperformance-improving louvers are formed between said tubes of said heat exchangers at said fins, and heat transfer prevention louvers are formed continuously along an area spanning a distance between said tubes of said adjacent heat exchangers at said fins,said heat transfer prevention louvers are formed continuous with, at least, said performance-improving louvers of one of said adjacent heat exchangers,wherein said tubes widths at said adjacent heat exchangers are different from each other, and an even number of louver groups are achieved by aligning roughly equal numbers of louvers evenly in series along said fins in a direction in which said adjacent heat exchangers are provided in parallel at said fins.
