Heat exchanging unit and heat exchanging apparatus.

摘要

A heat exchanging unit comprising a closed vessel (3) separated into first (1) and second (2) compartments by a vertical partition plate (4) thereby leaving a passage (5) above the vertical partition plate. The first compartment has a cooling medium inlet pipe (11) connected thereto, and a through pipe (13), through which a fluid to be cooled is passed, arranged to pass through the first compartment and including a heat exchange member (17) placed at a location lower than the top of the vertical partition plate. The second compartment is provided with a demister (21), and a cooling medium gas outlet pipe (22) connected to the demister. A cooling medium liquid outlet pipe (23) is connected to the second compartment. The heat exchanging unit is preferably used as part of a combined heat exchanging apparatus formed by combining the heat exchanging unit with a mist processing unit, or as part of a multistage heat exchanging apparatus formed by integrating two or more of the heat exchanging units.
