The subject invention pertains to a method and apparatus for cooling. In a specific
embodiment, the subject invention relates to a lightweight, compact, reliable,
and efficient cooling system. The subject system can provide heat stress relief
to individuals operating under, for example, hazardous conditions, or in elevated
temperatures, while wearing protective clothing. The subject invention also relates
to a condenser for transferring heat from a refrigerant to an external fluid in
thermal contact with the condenser. The subject condenser can have a heat transfer
surface and can be designed for an external fluid, such as air, to flow across
the heat transfer surface and allow the transfer of heat from heat transfer surface
to the external fluid. In a specific embodiment, the flow of the external fluid
is parallel to the heat transfer surface. In another specific embodiment, the heat
transfer surface can incorporate surface enhancements which enhance the transfer
of heat from the heat transfer surface to the external fluid. In another specific
embodiment, an outer layer can be positioned above the heat transfer surface to
create a volume between the heat transfer surface and the outer layer through which
the external fluid can flow.
