Title:
PARALLEL FLOW HEAT EXCHANGER AND AIR CONDITIONER USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/068687
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a parallel flow heat exchanger that, with a simple structure, induces a swirl flow inside a header tube and evenly distributes refrigerant to flat tubes. This parallel flow heat exchanger is provided with: first and second header tubes; a plurality of flat tubes connected to the first and second header tubes; an inflow tube which is connected to the first header tube and into which refrigerant flows; and an outflow tube which is connected to the second header tube and out of which refrigerant flows. The inflow tube is disposed such that the center axis of the inflow tube is offset with respect to the center axis of the first header tube.
