Abstract: A heat exchanger includes an inlet for receiving bulk solids, a plurality of heat transfer plate assemblies, a plurality of spacers disposed between adjacent heat transfer plate assemblies, and supports for supporting the heat transfer plate assemblies. The heat transfer plate assemblies include a first plate having a first pair of holes extending therethrough, the first plate having channels extending along a surface thereof, for the flow of fluid through the channels, and a second plate bonded to the first plate to enclose the channels, the second plate including a second pair of holes generally aligned with the first pair of holes to form through holes to facilitate flow of the fluid through the through holes and the channels.

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: 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 is directed towards a heat exchanger incorporating integral fin and turbulence enhancement features which are designed to improve hydraulic efficiency and heat transfer rates. The heat exchanger device comprises a top surface, a bottom surface, a front surface, a back surface, and two opposing side surfaces to define a main body unit. The heat exchanger device further comprises a plurality of laminar elements, or plates, having surface configurations to provide for to fluid flow therein. In order to increase heat transfer rates through the mixing of fluid, the heat exchanger device in accordance with the present invention contains features which enhance and increase flow turbulence and heat transfer surface area, referred to as out-of-plane structures. In one embodiment, the heat exchanger device contains features which form vertical out-of-plane structures. Alternatively, the heat exchanger device contains features which form horizontal out-of-plane structures.
