Summary

In order to develop Stirling cycle machines with a high efficiency, a suitable regenerator for each machine must be designed. To realize the flexibility of design and to improve the performance of the regenerator, a new matrix mesh sheet was proposed. It is a plate type with electrically etched holes. Each small hole is connected to neighbouring holes by grooves on the plate. The performance test in cooling mode was carried out with a 3-kW Stirling engine in order to measure its cooling performance. Three types of mesh sheets were developed and two of them were respectively stacked and installed in the machine. Also, the pressure and regenerator losses were compared with conventional stacked wire gauzes and the mesh sheets. From the results, it was clarified that the performance of the cooling mode was improved 5 to 40% by the mesh sheet. In this paper, the relation between the dimensions of the mesh sheet, the pressure and regenerator losses were also clarified.
