A cold plate having a copper base plate and a plurality of fins on the copper base plate. The fins are porous and made by 3D printing a copper-silver alloy on the copper base plate. Alternatively, the fins can be 3D printed and then adhered to the copper base plate with a brazing material. The copper base plate is placed on electronics to be cooled, such as a chip package, using a thermal interface material. An optional manifold can be placed on the copper base plate for circulating a coolant across the fins.

An integrated vapor chamber includes an outer shell and a plurality of composite capillary structures. The outer shell includes a flat casing and a plurality of partitions integrally formed. The flat shell includes a chamber, and the partitions are disposed in the chamber to separate the chamber into a plurality of flow channels. Each composite capillary structure is extended along each flow channel and distributed in the chamber. The composite capillary structure includes a metal mesh and a plurality of sintered powder uniformly sintered in the metal mesh. Furthermore, this disclosure also discloses a manufacturing method of the integrated vapor chamber. Therefore, the manufacturing method of the thin vapor chamber is simplified to improve the yield rate.

The invention provides a cross-flow separation element comprising a single-piece rigid porous support (2) having within its volume at least one channel (4.sub.1) for passing a flow of the fluid medium for treatment, which channel presents a flexuous flow volume (V1) defined by sweeping a generator section along a curvilinear path around a reference axis, and in that the reference axis does not intersect said generator section and is contained within the volume of the porous support.
