Publication number: 20140231055Abstract: 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.Type: ApplicationFiled: May 8, 2014Publication date: August 21, 2014Applicant: Vacuum Process Engineering, Inc.Inventor: Carl Schalansky

Publication number: 20140231057Abstract: 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.Type: ApplicationFiled: February 21, 2013Publication date: August 21, 2014Applicant: VACUUM PROCESS ENGINEERING, INC.Inventor: Carl Schalansky

Publication number: 20130213616Abstract: 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.Type: ApplicationFiled: March 15, 2013Publication date: August 22, 2013Applicant: Vacuum Process Engineering, Inc.Inventor: Vacuum Process Engineering, Inc.
