Title

Component Fabrication And Testing For A Meso-Scale Refrigerator

Abstract

Preliminary design of a meso-scale refrigerator is the focus of this paper. Two design variations for two different applications are presented here. The two intended applications are (1) an integrated heat removal system for electronics or photonic chips or modules, and (2) an actively cooled jacket for personnel. The proposed device is based on a vapor compression refrigeration cycle. The paper starts with a general system description and preliminary design along with a functional decomposition where the overall system function is decomposedin to nine major sub-functions. Different alternatives for compression and actuation are considered. Design specifications and some design details for each application are presented next. The specifics of the design requirements were found to suggest the same thermodynamic cycle for both applications, with the samet emperature lift of 48°C from 12°C to 60°C and an overall pressure ratio of 3.80 with R134a as the refrigerant. However, the details between the two designs are different. Design for electronic heat removal unit requires lower mass flow rate with lower compressor and actuator power and single stage compressionD. esign for actively cooledj acket requires higher mass flow rate and compressor and actuator power, and a 5-stage compression. The paper ends with the procedure for fabrication and testing for a micro-fabricated evaporator, which can be used for either application.
