Abstract

The two-phase thermosiphon heat exchanger is equipped with rows of vertically positioned, individually ribbed, closed on both sides tubes filled with refrigerant, placed inside a two-part housing. The lower edge of the upper part (4) and the upper edge of the lower part (5) of the housing are surrounded by flanges and of which the upper part (4) of the housing is equipped with connectors for supplying and draining the heated medium, and the lower part (5) of the housing with connectors for supplying and draining heating medium. The tubes are positioned relative to each other so that the tubes of each tube row are located between the tubes of the tube rows adjacent to it. In addition, the tubes are sealed tightly in the holes of the modular partition (3) from a thermal insulator, dividing the tubes into heated and cooled parts. The partition modules (3) are permanently connected to each other. To the ends of the partition (3) located between the flanges of the upper (4) and lower (5) part of the housing these flanges are attached. The tube parts embedded in the holes of the modular board (3) are not ribbed. Each tube is closed on both sides with plugs or on one side with a plug, and on the other with a refrigeration valve and filled with refrigerant. In addition, the heat exchanger is equipped with flow turbulators located in the spaces between the tubes, at least equal to the length of the tubes.
