Document Type and Number:
Japanese Patent JPH0212358
Kind Code:
B2
Abstract:
A heat exchanger for liquid/liquid heat exchange has a plurality of parallel vertical tubes arranged for the upward transport within the tubes of a first heat-exchange liquid, supply and discharge tanks for the first liquid into which the lower and upper ends of the tubes respectively open. A granular mass is fluidized during operation by the flow of the first liquid so as to occupy at least the tubes. Supply and discharge means for a second heat exchange liquid bring the second liquid into contact with the outer surface of the tubes. In order to improve the heat flow between the second liquid and the tubes, the supply means for the second liquid causes the second liquid to contact the tubes in the form of a film flowing downwardly along the outer surface of each tube.
