Abstract

A thermosiphon device includes one or more flat multiport tube structures having at least one section that defines a plurality of flow channels and at least one web that extends from the section in a plane of the flat multiport tube structures. The flow channels may function as condensing channels, e.g., in a counterflow device, or as evaporation channels. A multiport tube structure may include two sections that each define a plurality of flow channels and the two sections may be joined by a web that extends between the sections in the plane of the multiport tube structure. The sections may function as condensing channels, as evaporation channels, or one section may function as a set of evaporation channel and the other section may function as a set of condensing channels. Multiport tube sections may alternately function as a vapor supply path or liquid return path.
