Abstract:
A heat transfer media that provides more complete and more even use of the media volume by enhancing the characteristics and/or directions of fluid flow across the media. The heat transfer media includes a heat transfer block having one or more layers that include longitudinal flow passages for enabling fluid flow in the longitudinal direction across each layer, and also include transverse flow passage for enabling lateral cross-flow between the longitudinal flow passages. The heat transfer block may include a plurality of stackable plates, with each plate having fins laterally spaced apart to define longitudinally extending channels, and at least one aperture extending transversely through at least one fin for enabling transverse cross-flow between the longitudinal channels. The aperture may be configured as a recessed groove in the fin, and the fin may have ridge portions longitudinally spaced apart to at least partially define the recessed groove.
Abstract:
The present invention refers to a heat exchanger, in particular to a heat exchanger produced according to Roll-Bond method, comprising at least one plate made of thermally conductive material which comprises channels to enable flowing of heat-transfer medium. According to the invention, the heat exchanger is formed of a plurality of plates formed in a sense of a spiral, wherein at least one of the flat sides of the plates (1, 2) of the heat exchanger is provided with at least one means (5, 6) for improving heat transfer.
Abstract:
3D printed thermal management devices and corresponding methods of manufacturing are described herein. A thermal management device includes a single contiguous component including at least a portion of a first heat exchanger and at least a portion of a second heat exchanger. The second heat exchanger is of a different type than the first heat exchanger.
Abstract:
A stack of heating surface elements includes a first heating surface element (4) having first (10), second (12) and third (14) zones arranged sequentially along a primary gas flow direction (A). The first zone (10) includes a herringbone structure, the second zone (12) includes a flat structure, and the third zone (14) includes a plurality of corrugations extending in the primary gas flow direction (A). The corrugations have flat peak and trough regions. The stack also includes a second heating surface element (36), where the second heating surface element includes a plurality of corrugations extending in the primary gas flow direction (A).
Abstract:
A heat exchanger is provided and includes a shell extending between opposing tube sheets to define an interior, nozzles coupled to the shell by which a first fluid is communicated with the interior and a tubular body extending between the opposing tube sheets to transmit a second fluid through the interior whereby heat transfer occurs between the first and second fluids along a heat transfer portion of the tubular body defined from respective planes of opposing faces of the opposing tube sheets, the heat transfer portion having at least first and second topologies at first and second sections thereof, respectively, which are respectively disposed proximate to the respective planes of the opposing faces of the opposing tube sheets.
