Abstract
A 2-cylinder opposite-positioned alpha-type Stirling engine for testing the heat exchangers, including the heater, cooler and regenerator, is being under construction. It is composed of two alpha-type Stirling engines with the two expansion cylinders and the two compression cylinders being respectively opposite-positioned on the same horizontal plane by using a master-and-slaves connecting rod set, resembling a radial engine with four cylinders. Such a configuration as well as the three external heat exchangers makes it convenient to replace and/or test any one or any combination of these heat exchangers on one hand, and on the other hand, avoiding the interference of various measuring instruments possibly used in the future.
