Abstract: The present invention relates to thermosyphons, in particular for use in the cooling of electronic components. In a first embodiment a thermosyphon is manufactured by extruding a base (1) and milling a channel structure in the base to produce a plurality of fins (5) extending vertically from the base. A lid (3) comprising a number of fins (4) extending vertically from the lid is placed over the heat sink channel structure so that a thermosyphon of an expanding channel system is formed. In a second embodiment the evaporator and condenser sections are separated and connected by pipes. To form a leak proof seal between the lid and the base, joining is preferably done by friction stir welding. By providing an extruded thermosyphon, heat transfer is made more efficient than when junctions are used. The present invention provides a new way of efficiently manufacturing an integrated structure, while keeping the heat transfer of the structure high.

Abstract: The present invention is related to a heat sink unit comprising a base (1) and a number of fins extending from the base, said heat sink unit having an extended surface area formed by microfins (2) inserted between the extruded fins. The microfins are formed by folding a strip having a clad braze layer on both sides. The microfins are preferably brazed to the extruded structure by heating the structure after the fins have been inserted to a temperature higher than the melting point of the clad braze.

Abstract: A method for manufacturing a one-sided heat sink from a plurality of individual lamellas each including a base and a fin portion extending from the top surface base portion. The base portion is wider than the fin portion. The base portions of a plurality of lamellas are aligned such that the fin portions of each lamella extend in one direction and side surfaces of adjacent base portions face each other while the bottom portions form an even surface of the heat sink. A force is applied to side surfaces of the base portions of outermost lamellas such that the lamellas are urged into contact with each other. The bottom surfaces of the base portions are welded together.
