ABSTRACT:
The present invention provides a two-phase thermosyphon (100) and a method for forming the two-phase thermosyphon (100). The two-phase thermosyphon (100) includes a hermetically sealed housing (101) including a first outer surface (107), a second outer surface (109) opposite the first outer surface (107), a first inner surface (111), and a second inner surface (113). The two-phase thermosyphon (100) also includes a finned area (114) thermally coupled to the hermetically sealed housing (101), the finned area (114) including a plurality of fins (115) disposed on a part of the first outer surface (107). The two-phase thermosyphon (100) also includes a plurality of air feed through slots (105) disposed in the housing (101). The air feed through slots (105) underlie the fins(115) and provide increased heat dissipation by increasing the air flow about the fins (115). The present invention is particularly useful in applications that require a two-phase thermosyphon utilized in a generally horizontal orientation.
