Abstract
A heat exchanger includes a plurality of spaced-apart plates and a plurality of spacers that separate the plates. The plates and spacers cooperate to form hot-side and cold-side passageways. The plates are made of a thermally and electrically conductive material, and the spacers are made of an electrically non-conductive material. A voltage is applied across the plates to electro-hydrodynamically increase heat transfer efficiency of the heat exchanger.
Claims15
A heat exchanger comprising:
- a plurality of carbon-carbon plates stacked in a substantially parallel spaced-apart relationship, the plates being thermally and electrically conductive;
- and
- a plurality of electrically non-conductive carbon spacers located between the plates;
- the spacers and the plates cooperating to define hot-side and cold-side passageways.
