Patent Images
1. A projection system comprising:
- at least one heat source within the projection system;
a closed-loop heat pipe having at least one heat receiving portion and at least one heat rejecting portion, wherein the at least one heat receiving portion is thermally coupled with the at least one heat source, and wherein the at least one heat rejecting portion is thermally coupled with a heat sink; and
a heat carrying fluid circulating through the heat pipe, the heat carrying fluid receiving heat from the at least one heat source and releasing heat to the heat sink.

Abstract
A projection system has at least one heat source. A closed-loop heat pipe has at least one heat receiving portion thermally coupled with the at least one heat source, and at least one heat rejecting portion thermally coupled with a heat sink. A heat carrying fluid circulating through the heat pipe receives heat from the at least one heat source and releases heat to the heat sink.

9. A projection system comprising:
-
a projector component;
an evaporator thermally coupled with the projector component, the evaporator configured to dissipate heat from the projector component by evaporating liquid working fluid from a stream of liquid working fluid to produce a stream of working fluid vapor; and
a condenser configured to dissipate heat from the stream of working fluid vapor to add liquid working fluid to the stream of liquid working fluid. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
