...Cheng-Wei Tien; Kun-Huang Yu; Wen-Junn Sheu; Chi-Chuan Wang This study examines the refrigerant distribution of a dual cold-plate system subject to the influence of heating load, using a R-134a based vapor compression system with a nominal capacity ranging from 50 W to 250 W. The cold plate...

...Victor Chiriac; Florea Chiriac Classical refrigeration using vapor compression has been widely applied over the past decades to large-scale industrial systems, with few known applications to the microelectronic cooling field, due to the small size limitation. The present study proposes an efficient...

... and thermohydraulic performance evaluation of high heat flux evaporators suitable for interfacing the microprocessor chip with a cascaded R134a∕R508b vapor compression refrigeration system at − 80 ° C . Four compact evaporator designs are examined—a base line slit-flow structure with no microfeatures, straight...

... as an evaporator in an R134a refrigeration loop. This system is capable of maintaining device temperatures below 55 ° C while dissipating in excess of 100 W ∕ cm 2 . It is shown that while higher heat transfer coefficients are possible with greater mass velocities, those conditions are typically associated...

.... The current research focuses on mainframes (computer system), which uses a conventional refrigeration system to maintain chip temperatures below that of comparable air-cooled systems, but well above cryogenic temperatures. Multivariable control of compressor speed along with thermostatic expansion valve (TXV...
