Abstract
A system provides convective transfer from a workpiece to a flowing fluid. A gap is formed between the workpiece and a facesheet containing fluid supply nozzles and fluid return nozzles. The fluid is fed to the supply nozzles, travels a short distance within the gap adjacent to the facesheet, and exits via return nozzles. The flow cross section and flow density facilitate heat transfer at a moderate flow rate and low fluid pressure. The system is also applicable for chemical transfer such as plating or etching printed circuit boards and for transfer through a semi-permeable membrane.
Claims18
A system for convective transfer from a smooth coldsheet comprising:
- fluid supply means including a plurality of supply nozzles;
- fluid return means including a plurality of return nozzles;
- and
- a facesheet coupled to said fluid supply means and said fluid return means disposed opposite the smooth coldsheet thereby forming a gap between said facesheet and the coldsheet so that a fluid flows through said fluid supply means and said plurality of supply nozzles along short segments through the gap and through said plurality of return nozzles and said fluid return means, where the length of said segment is less than approximately 32 times the gap distance between said facesheet and the coldsheet.
A system for convective transfer comprising:
- a plurality of fluid supply means;
- a plurality of fluid return means;
- and
- a facesheet coupled to said plurality of fluid supply means and said plurality of fluid return means whereby when said facesheet is disposed opposite a smooth coldsheet a plurality of gaps are formed therebetween so that a fluid flows through said plurality of fluid supply means, through a plurality of topologically parallel flow segments through the plurality of gaps and through said plurality of fluid return means, where said segments are less than approximately 32 times the gap formed between said facesheet and the coldsheet.
