ABSTRACT:
A condenser (44) of a heated fluid which is condensed within a core of the condenser in response to heat exchange between the heated fluid and a coolant fluid flowing through the core in accordance with the invention includes a plurality of heat conductive laminates (70 and 72) having at least one first channel (12) through which the fluid being condensed flows and at least one second channel (14) through which the coolant flows. The cross-sectional area of at least one of the at least one first channel in the condenser decreases in a direction of fluid flow through the condenser producing increased velocity of the heated fluid flowing in the direction of fluid flow causing a shear force between a vapor phase of the heated fluid and liquid phase condensed on a perimeter of at least one first channel which causes the fluid phase to flow through the at least one channel.
