Minimizing Temperature Gradient in Photonic Sintering for Defect‐Free High‐Conductivity Cu‐Based Printed Patterns by Bidirectional Irradiation

Abstract Research in termoacoustics began with the observation of the heat transfer between gas and solids. Using this interaction the intense sound wave could be applied to create engines and heat pumps. The most important part of thermoacoustic devices is a regenerator, where press of conversion of sound energy into thermal or vice versa takes place. In a heat pump the acoustic wave produces the temperature difference at the two ends of the regenerator. The aim of the paper is to find the influence of the material used for the construction of a regenerator on the properties of a thermoacoustic heat pump. Modern technologies allow us to create new materials with physical properties necessary to increase the temperature gradient on the heat exchangers. The aim of this paper is to create a regenerator which strongly improves the efficiency of the heat pump.

Abstract ANACONDA Alloy 1870 is a free-cutting high-conductivity copper. It is a deoxidized copper with lead added to impart free-cutting properties. The various and unusual properties of Alloy 1870 make it suitable for many applications in the manufacture of parts machined from rods and for current-carrying studs, nuts and bolts designed for use at normal temperatures. Because it is deoxidized, it is not susceptible to hydrogen embrittlement if heated in a reducing atmosphere. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-318. Producer or source: Anaconda American Brass Company.
