DEVICE FOR DECREASING THE START-UP TIME FOR STIRLING ENGINES

摘要

A DEVICE FOR DECREASING THE START-UP TIME FOR STIRLING ENGINES The closed fluid working system of a Stirling cycle engine is disclosed having incorporated therein an improved regenerator assembly which modifies the thermodynamic responsiveness of the working system particularly during cold-start conditions. A foraminous regenerator matrix is constructed with a predetermined matrix heat capacity to void volume ratio, and has invested therein an electrical heating element arranged in thermally conductive relationship with a desired zone of the matrix. The heating element is controlled to be energized for attaining precise heat exchange conditions within the matrix.
