Transducer e.g. thermoelectric transducer, for converting temperature difference into pressure difference in stirling engine of ship, has revolving door mechanism precluding direct flow of working fluid between entry port and exit orifice

摘要

#CMT# #/CMT# The transducer has an entry port (4) through which working fluid e.g. gas, enters into a revolving door mechanism (1), and an exit orifice (5) through which the fluid exits out from the mechanism. A thermal insulator (11) is arranged between a hot wall (9) and a cold wall (10). The mechanism precludes a direct flow of the fluid between the entry port and the exit orifice such that pressure of the fluid is increased when the fluid is induced from the entry port to the exit orifice, and the pressure of the fluid is decreased when the fluid is induced from the exit orifice to the entry port. #CMT#USE : #/CMT# Transducer e.g. thermal pneumatic transducer and thermoelectric transducer (all claimed) for converting temperature difference into pressure difference, for a solar thermal energy generation application, a mobile and decentralized electricity generation application, an industrial waste heat utilization application, and in a combustion engine i.e. stirling engine, of a ship. #CMT#ADVANTAGE : #/CMT# The transducer utilizes thermal energy in a simple and inexpensive manner. The pressure difference is increased by serially connecting multiple transducers as required. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a thermal pneumatic transducer.'(Drawing includes non-English language text)' 1 : Revolving door mechanism 4 : Entry port 5 : Exit orifice 9 : Hot wall 10 : Cold wall 11 : Thermal insulator.
