Abstract

A thermosiphon device includes a closed loop evaporator section having one or more evaporation channels that are fed by a liquid return path, and a condenser section with one or more condensing channels. The condenser section may include a vapor supply path that is adjacent one or more condensing channels, e.g., located between two sets of condensing channels. Evaporator and/or condenser sections may be made from a single, flat bent tube, which may be bent about an axis parallel to the plane of the flat tube to form a turnaround and/or twisted about an axis along a length of the tube at the tube ends. A single tube may form both evaporator and condenser sections of a thermosiphon device, and an axially extending wall inside the tube in the evaporator section may separate an evaporator section from a liquid return section.
