AIR COOLING UNIT

摘要

PROBLEM TO BE SOLVED: To provide a technique for efficiently cooling a working medium of a Rankine cycle with air.SOLUTION: An air cooling unit (100) is used in a Rankine cycle device (106), and comprises an expander (11) and a condenser (12). The expander (11) expands a working medium to recover energy. The condenser (12) cools the working medium with air. The cooling unit (100) comprises a heat transfer reducing body that reduces heat transfer between the expander (11) and an air passage.
