Abstract
Abstract An arrangement for transmitting heat using a tubular member defining a chamber in which an evaporable and wetting liquid substance and at least one capillary body for conducting the liquid substance are present includes an inner wall having grooves defined therealong which extend crosswise to the direction of flow of the liquid in the capillary body. The capillary body or wick may be in the form of a narrow meshed wire netting and the arrangement advantageously includes one or more capillary webs which touch the evaporable liquid present in the grooves of the chamber wall. The capillary body is advantageously formed as a tube or jacket, for example, from a single piece of a wire netting or of a metal sheet provided with capillary passages. The capillary tube may be formed of a plurality of segments or partial wall areas which are joined together over the capillary webs which extend from the tubes out to the grooves of the wall of the chamber.
