Abstract

The present invention relates to a Stirling cycle-based heat engine system which can utilize various types of energy such as liquid fuel, gas fuel, solid fuel, waste heat from power plants and factories, geothermal energy, solar energy, and the like as power sources to overcome the problems of a Stirling engine. The Stirling cycle-based heat engine system (10) includes a pumping unit (20), a driving unit (30), and a connection line (50). A heat medium may flow in one direction through the pumping unit (20), the driving unit (30) and the connection line (50) connecting the pumping unit (20) to the driving unit (30) to flow to the outside (or in a closed circuit through circulation). Thus, heat exchange bottlenecking which occurs in heat engine systems according to a related art may be prevented, and also, a limited heat exchange area may be relatively freely expanded. In addition, the flow of the heat medium may be formed without cooling to operate a driving body such as an engine.
