“…Most recent development in the field of cooling electronics was a development and analysis of miniature system for harsh environments by Zhou and Li [21]. Main application was in-vehicle electronics cooling, where 2 kg system with dimensions of 380 × 350 x × 58 mm 3 reached 100 W of cooling power with COP of 2.25 at evaporating and condensation temperatures in range of 0 to 20 °C and 40 to 85 °C, respectively.…”

Thermal management is becoming more challenging due to the increasing compactness and computational power of appliances. Affordable and efficient solutions include active liquid cooling methods, thermoelectric cooling, and the use of heat pipes. From these, vapour-compression technologies achieve the highest power density. However, the downscaling of vapour-compression for cooling of personal computers or workstations is rather problematic from several different reasons. The first problem concerns the low second law efficiency of miniature vapour-compression systems. The second problem concerns the available space occupation of such a cooling system. Moreover, miniature and high-power density condensers and evaporators have not yet been adequately researched and developed to date. In this review, we present several vapour-compression refrigeration systems that are based in some way on the miniaturisation of systems or individual components – evaporators, condensers, and compressors. These are presented and compared in terms of cooling power, COP, and the second law efficiency. At the end of the manuscript, guidelines for future improvements and the implementation of miniature vapour-compression systems are presented.

“…It was a copper plate 400 mm long, 20 mm wide, and 10 mm thick with three guides milled on the top side to weld a tube for refrigerant flow with a total length of 1.2 m; on the bottom side, two more guides were machined to hold a resistance wire, which simulated the heat load. To develop a more economical system, a simple porous media evaporator was used in a simple structured and economical miniature VCR system presented by Zhou and Li [100] for the cooling of electronic components within the automotive sector. The above is based on the scoop that microchannel heat exchangers continue to be very expensive.…”

“…becomes more challenging [1]. As traditional fan-fin air cooling methods become less viable for high-powered processors and components, there is a growing interest in refrigeration technology as a means to improve thermal management [2][3][4]. Liquid-based cooling technology, leveraging superior thermophysical properties, emerges as a compelling solution for high-performance processors.…”

This study presents a numerical model of a miniature vapor compression refrigeration (VCR) system that is used to cool liquid coolant in a secondary pumped loop that is deployed to cool a high-powered CPU. The model employs a physical approach and iterative algorithms to solve coupled non-linear equations for both the refrigeration cycle and pumped single phase cooling loop. Experimental tests were conducted to verify the model using an in-house test facility. This paper outlines the modelling and solution approaches taken, discusses the efficacy of the model in terms of agreement with experimental measurements, and highlights the utility of the model as a design tool for cooling high powered electronics.
