“…The COP of a thermoelectric cooler ranges from approximately. 0.3 to 0.6, increasing with the heat sink's ability to extract generated heat from the hot side of the junction [33]. Peltier-based ice plates are only recently available in the industrial marketplace [34].…”

Workholding and fixturing is a critically important aspect of manufacturing that has direct implications for the quality of the manufactured component during processing as well as a direct impact on the cost of the component. The field of workholding is mature with numerous techniques employed, mostly using contact pressure, but also using magnetics and adhesives. Looking to nature for inspiration presents us with the use of ice as a mechanism for adhesion, referred to as cryo-adhesion. Cryo-adhesion offers some advantages over more traditional fixturing methods such as removing contact pressure and therefore reducing the dependence on the machining of complex, intricate bespoke fixtures. While the concept of ice adhesion is known, there is minimal research presented on the application of ice adhesion in manufacturing processes. This research reports on the development of a novel Peltier-based cryo-cooling fixture for workholding in manufacturing operations. The research provides insight into the main interactions that might be experienced in manufacturing type scenarios and presents findings on the cryo fixture's thermal and geometric characteristics, the use of the novel cryo fixture for holding various materials under tensile and shear loads, and a consideration of contact area and surface roughness on the cryo fixture performance.

Abstract-The primary drawback of thermoelectric coolers (TECs) for electronics cooling applications is their thermodynamic inefficiency due to material limitations. The present work considers a control strategy to improve the overall coefficient of performance in an engineering system instead of addressing material shortcomings. Typical TECs are composed of several individual thermocouples that are powered in series and remove heat in parallel. If one of the numerous thermocouples is powered, all the thermocouples receive the same power whether or not they are needed. The fact that chips heat nonuniformly provides an opportunity for performance enhancement, by sensing and controlling the power to individual couples within the device. The current work presents evidence that applying distributed control to TEC operation can realize appreciable improvement in performance. Compared to monolithic cooling devices, a distributed control strategy can realize a factor of 2 increase in performance for the device studied. Additionally, this type of control can be used in conjunction with many of the existing material-based research initiatives to further compound the benefits.

“…Boiling heat transfer is widely used because of low temperature difference, high heat flow density, and other heat transfer characteristics, and the effect of porous wick heat pipe in the boiling heat transfer characteristics is increasingly explored [8,9]. The addition of porous wick in the tube can significantly enhance the boil ing heat transfer of heat flow and reduce surface superheat.…”
