ABSTRACT:
A heat exchanger (38) is provided which may be used in a mass transfer device (20), such asn an oxygenator or a dialyzer. The heat exchanger comprises a core (40) formed of a corrugated metal having a high thermal conductivity. Each of the corrugations of the core comprises substantially parallel side walls (70, 72). A first fluid, such as blood, is introduced onto the outside of the core. A second fluid, such as water, is introduced into the inside of the core. The first and second fluids will be in heat exchange relationship with each other and the flow of the fluids is substantially uniform resulting from the substantially parallel side walls of the corrugations. The core is formed by providing a flexible metalhose, annealing the flexible metal hose, compressing the annealed hose and expanding the compressed hose to a length that is substantially less than its original length but greater than its length during compression.
