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.

Abstract: A thermosiphon device including one or more multi-port tubes that form both an evaporator section and a condenser section for the device. The one or more tubes may be flat tubes with multiple, parallel flow channels, and may be bent to form a bend between the evaporator and condenser sections of the tube(s). One or more flow channels of the tube at the bend may provide a vapor flow path or a liquid flow path between the evaporator and condenser sections.

Abstract: A thermosiphon device includes an evaporator section that is formed as a single integrated part including one or more evaporation channels and a liquid return path, and/or includes a condenser section that is formed as a single integrated part including one or more condensing channels and a vapor supply path. A single manifold may include vapor and liquid chambers that are separate from each other and that fluidly connect evaporation channels with the vapor supply path and fluidly connect condensing channels with the liquid return path, respectively. Portions of the evaporator or condenser section that define the liquid return path or vapor supply path, respectively, may be free of any fins or other thermal transfer structure.

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.

Abstract: A method for inactivating target cells in the presence of T cells by bringing the two types of cells in contact with a superantigen (SAG) in the presence of an immune modulator, characterized in that at least one of the superantigen and the immune modulator is in the form of a conjugate between a “free” superantigen (Sag) and a moiety targeting the conjugate to the target cells. A superantigen conjugate complying with the formula (1) (T)x(Sag)y(IM)z; a) T is a targeting moiety, Sag corresponds to a free superantigen, IM is an immune modulator that is not a superantigen and T, Sag and IM are linked together via organic linkers B; b) x, y and z are integers that typically are selected among 0-10 and represent the number of moieties T, Sag and IM, respectively, in a given conjugate molecule, with the provision that y>0 and also one or both of x and z>0. The superantigen conjugate is preferably a triple fusion protein.
