The most conventional parallel-flow heat exchanger is usually micro-channel flat parallel-flow heat exchanger, and its agent structure includes micro-channel flat and U-shaped louvered fin, and both are fixed by soldering.In order to ensure between louvered fin and micro-channel flat can heat exchange well, reduce thermal contact resistance between the two, usual fin be all closely to weld between flat tube.When heat exchanger is horizontal, flat tube can stop flowing down of condensed water；When heat exchanger is vertically arranged, fin can stop flowing down of condensed water.The most no matter parallel-flow heat exchanger is horizontal or is vertically arranged, and is all unfavorable for the discharge of condensed water.And study and show, the frosting of heat exchanger is always from the beginning of condensing the position that water is assembled, and frosting is the most serious in this place, and therefore the flat tube of Conventional parallel stream heat exchanger is not suitable for being applied in vaporizer with the combination of U-shaped fin.
Summary of the invention
In view of the above problems, the purpose of the embodiment of the present invention is to provide a kind of parallel-flow heat exchanger and air conditioning system, still can keep higher heat exchange property when as vaporizer.
A kind of parallel-flow heat exchanger that the embodiment of the present invention provides, it is made up of the comb of predetermined number including some groups of comb bundles, described comb bundle, described comb is the capillary tube of a fixed-caliber, the two ends of described comb are inserted respectively in the header at two ends, often organize and leave space between the comb of described comb Shu Xianglin, often organize and between described comb bundle, be provided with corrugated fin, several baffle plates built-in in described header, header is separated into multiple flow process.
