Abstract
A heat exchanger, internal to an injector for a variable spray fuel injection system, uses nucleate boiling to maximize the heat flux from the heated metal to the fuel, wherein the nucleate boiling occurs along a control surface characterized by features conducive to generating detaching bubbles to transfer heat energy in a vapor flux. The source of heat flux may be an induction heater coil magnetically coupled to an appropriate loss component so that fuel inside a fuel component is heated to a desired temperature.
Claims12
A variable spray injector with a heat exchanger comprising:
- a loss component;
- a surface configured to facilitate nucleate boiling heat transfer;
- and
- a fluidic and gaseous coupling between a fluid to be heated and the surface.
