A Review of Precision Engine Cooling

Although successful “precision cooled” prototype engines have been demonstrated, the design of most mainstream coolant jackets has evolved only cautiously, and lacked this major change in approach.

The achievements and potential of precision cooling are reviewed, along with an extension into nucleate boiling based heat transfer. It is demonstrated that ideas for advanced “external” cooling systems with low flowrates are in fact extremely compatible with the “internal” precision engine cooling philosophy, and in combination promise even larger benefits.
