Plate-fin heat exchanger with controls therefor

DETAILED DESCRIPTION The present invention is directed to a heat exchanger of the multiple plate and fin type used for evaporating a refrigerant.
In order to reduce the static height of the liquid and thus overcome some of the difficulties or problems as mentioned herein above, the present invention utilizes a heat exchanger in the form of an evaporator having water passages flowing in planes perpendicular to the passageways for the liquid refrigerant.
In order to reduce the static head penalty, the heat exchanger assembly is divided into a plurality of compartments or boiling chambers with the various chambers or compartments being disposed or arranged in super imposed relation to one another.
While there is no apparent limit or restriction to the number of chamber compartments that could be employed, the present application discloses for purposes of illustration, a heat exchanger having three chambers or compartments.
