Study on Cooling Performance of Stirling Cycle Machine with New Regenerator Matrix

Abstract

In order to develop Stirling cycle machines with high efficiency, suitable regenerator for each machine must be designed. To realize the flexibility of design and to improve the performance of regenerator, a new matrix, mesh sheet was proposed. It is a plate type with electrically etched holes. And one made with stainless steel, and the other made with nickel. The performance test of cooling mode was carried out with a 3-kW Stirling engine in order to measure its cooling performance. Two types of mesh sheet were respectively and alternate stacking to install in the machine. From the results, it was clarified that the performance of the cooling mode was improved about 3 to 7% by the mesh sheet. In this paper, the relation between the performance and the operating conditions by using conventional wire gauze and mesh sheets was also clarified.
