Abstract: Hybrid additive featured plates used to form an overall microchannel heat exchanger and corresponding method of manufacture are disclosed. Various additive manufacturing (AM) techniques may be used to form walls defining microchannel features on a plate substrate. The manufacturing method is a hybrid process in that leverages both additive and conventional manufacturing techniques to minimize both cost and fabrication time.

Abstract: An additive manufacturing process is described that is particularly useful in the production of compact heat exchangers, chemical reactors, static chemical mixers and recuperators.

Abstract: The present invention provides a heat exchanging device, formable into a three dimensional configuration. The heat exchanger device may be of the heat sink type, a dual fluid type, or virtually any other as may be desired. The heat exchanger device comprises a main body which is formable into a three dimensional shape and has a plurality of individual subunit elements adapted to form a plurality of stacked heat exchanging units. The individual subunits have surface configurations which are adapted to allow fluid flow. The present invention also describes devices, methods of making a heat exchanging device and/or methods of attaching external components to the heat exchanging device without damaging internal structures.

Abstract: The present invention describes a heat exchanger and method of making the heat exchanger having flow directors for directing the flow of fluids to one or more portions of the heat exchanger. The heat exchanger comprises a main body adapted for heat exchange having a plurality of channels adapted to receive fluid flow. The heat exchanger also includes a plurality of heat exchanging elements which provide exchange of heat as fluid flows therein and defines one or more fluid flow channels. At least one flow director is adapted for directing fluid flow from an external source to the fluid flow channels, whereby hydraulic efficiency is maximized by preventing fluid turbulence associated with non-directed flow of fluid within.

Abstract: An electric heating film comprising of an first polymeric layer having a top surface and bottom surface, a second polymeric layer, a metalized surface, and conductive bus electrodes. The top surface of the first polymeric layer includes a continuous metalized surface of vacuum deposited metal coating and at least one pair of parallel spaced conductive bus electrodes, i.e. copper strips, for connection to a power source. The conductive bus electrodes are conductively adhered to the metalized surface to distribute an electrical current onto the metalized surface to provide a heat across the metalized surface. The second polymeric film sheet layer is provided as a protective layer positioned atop of the top surface of the first polymeric film sheet or enclosing the top and bottom surface of the first polymeric film sheet.

Abstract: The instant invention provides a means and method for producing multi-laminar elements, said elements being suitable for operation in high temperature, atmospheric or vacuum environments such as those which may be required when processing materials such as substrates for semiconductors or for chemical vapor deposition.
