Abstract (en)
A heat exchanger (1) having at least one header (2), the whole of which is integrally formed by extrusion or drawing and in which a plurality of fluid passages are provided in parallel to each other and parted from each other, and a plurality of tubes (4), characterized in that a first partition (11) is provided in a first fluid passage, a second partition (12) is provided in a second fluid passage at a position different from a position of the first partition (11) in a fluid passage extending direction, and a communication path (14) is provided to a partition wall parting the first and second passages from each other at a position between the first and second partitions (11, 12) to communicate the first and second passages with each other. A counter flow structure suitable for a heat exchanger using carbon dioxide refrigerant can be easily realized at a simple assembling work and a high processing accuracy.
