Abstract
Abstract Disclosed herein is a heat exchanger for altering the temperature of process streams by the use of a plurality of tube bundles made of organic polymeric material disposed within at least one tank having process stream inlet and outlet means. The end portions of the tube bundles are operatively connected to feed and discharge means forming a passageway for circulation of a second liquid through the tube bundles. The tube bundles extend the entire length of the tank and in combination with flow distribution means form an uninterrupted heat exchange region through which only process liquid passing through the heat exchange region leaves the tank.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
191 words
An apparatus for accomplishing heat exchange between a flowing first liquid and a second liquid having a temperature significantly different from that of the first liquid which comprises a. an elongated tank having an input means for receiving the flowing first liquid and an output means by which the flowing first liquid exits, b. a plurality of tube bundles each of which comprises a plurality of small diameter flexible tubes made from an organic polymer composition, one end of each of which bundles is coupled to an inlet means while the other end is coupled to an outlet means to permit the flow of the second liquid through the interior of the tubes, each tube bundle being disposed within and extending substantially from the top to the bottom of the tank and in relationship to the input and output means of the tank such that a substantially unbroken heat exchange region is provided and the tank is divided into an input side and an output side, c. means for directing the passage of a substantially uniform volume of the first liquid substantially radially through each unit area of the tube bundles.
