Abstract
A passive cooling system for cooling an enclosure containing electronic components. A hollowed portion of the enclosure is formed as an integral heat pipe containing a working fluid. The hollowed portion has an evaporator section located at the top and a condenser section located at the bottom. The enclosure also has hollowed side walls which serve as passage ways for the working fluid to flow through in between the evaporator and condenser sections. Gravity and the pressure of evaporation force the working fluid down to the condenser section. A wick is provided for returning the working fluid to the evaporator section by capillary action. Additionally, an ultrasonic transducer driven by the heat rejected from the condenser section may be used to help return the working fluid to the evaporator section. Finally, a check valve may be employed before the evaporator section for the working fluid to flow through.

12. A passive cooling system for cooling heat generating components comprising:
-
a storage means for housing heat generating components; a hollowed portion in said storage means for forming an integral heat pipe; a working fluid contained within said hollowed portion; an evaporator means located at a top of said hollowed portion for vaporizing said working fluid into a vapor working fluid; a condenser means located at a bottom of said hollowed portion for condensing said working fluid into a liquid working fluid; a first connector means for said vapor working fluid to flow down to said condenser means; a second connector means for said liquid working fluid to flow up to said evaporator means; a means for returning said liquid working fluid to said evaporator means located in said second connector means; and a means for preventing reverse flow located in said second connector means. - View Dependent Claims (13, 14, 15, 16, 17, 18)
