Numerical Analysis of a Miniature-Scale Refrigeration System (MSRS) for Electronics Cooling

This paper presents the numerical analysis of a Miniature-Scale Refrigeration System (MSRS) for electronics cooling. The system consists of a simulated electronic chip attached to a microchannel cold plate evaporator, a compressor, a microchannel condenser, and an expansion device. The system uses R-134a as the refrigerant. A copper block heater is designed to simulate the heat generation of an...

Review of Refrigeration Technologies for High Heat Dissipation Electronics Cooling

It is envisioned that conventional air cooling techniques using heat sinks are not able to sufficiently cool future generations of high heat dissipation semiconductor processors. Thus, alternative cooling approaches are being extensively studied as substitutes. This paper presents a literature review of the available refrigeration systems and system simulation models for electronics cooling. Th...

Theoretical Model for Condenser of Miniature LiBr-H2O Vapor Absorption Refrigeration System

The microchannels/minichannels are being used in industry to yield compact geometry for heat transfer in a wide variety of application. The channels provide high heat transfer coefficients and the large surface area to volume ratios, has led to their use in compact condensers for air-conditioning and refrigerant systems. In order to achieve the compactness the present work attempts to develop a...
