Modeling of MEMS-type Devices for Microprocessor Cooling
نویسندگان
چکیده
This paper discusses the use of MEMS-type devices for the cooling of microprocessors. Vapor compression refrigerators and circulated-coolant heat-exchange systems are analyzed. Water and commercial refrigerants are considered as working fluids. Calculations indicate that although vapor compression systems are capable of removing greater amounts of heat, circulated-coolant systems are far more practical in terms of size and power requirements. The use of a circulated-coolant system can remove up to 400 W of heat from microprocessors at 120°C to ambient air at 35°C, about three times the heat removal current heat-sink systems achieve.
