Title:
THERMOACOUSTIC TEMPERATURE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/049221
Kind Code:
A1
Abstract:
This thermoacoustic temperature control system comprises a pipe (10) that is filled with a working gas, a motor (20), and a load (30). The motor (20) has a motor-side thermal accumulator (21) and motor-side heat exchangers (22, 23) connected to both ends of the thermal accumulator. The load (30) has a load-side thermal accumulator (31) and load-side heat exchangers (32, 33) connected to both ends of the thermal accumulator. The pipe (10) comprises a ring-shaped annular pipe section (11), and a branching pipe section (12) that branches from a branching point (p) on the annular pipe section (11). The motor (20) is incorporated in the branching pipe section (12), and the load (30) is incorporated in the annular pipe section (11). A blocking membrane (40) that prevents the working gas from passing through and that can vibrate in association with vibrations of the working gas is inserted in a position near the branching point (p) in the annular pipe section (11) between the low temperature side load-side heat exchanger (33) and the branching point (p). According to this configuration, the durability of the blocking membrane inserted in a portion of the annular pipe section can be improved.
