Title:
THERMOACOUSTIC ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/102564
Kind Code:
A1
Abstract:
A thermoacoustic engine 110, which is incorporated in a thermoacoustic pipe 102 in which a working gas is sealed, comprises: a heat storage device 111 having a plurality of flow paths 111c penetrating in the longitudinal direction; a high-temperature-side heat exchanger 112 coupled to one end of the heat storage device; and a low-temperature-side heat exchanger 113 coupled to the other end of the heat storage device. The high-temperature-side heat exchanger comprises: a first section 112a connected to the one end of the heat storage device and in which a first opening 112a1 through which the working gas passes is formed; a second section 112b, which is interposed in a fluid passage 120 positioned on the outside of the thermoacoustic pipe and through which a fluid having a higher temperature than room temperature passes, and in which a second opening 112b1 through which the fluid passes is formed; and a connecting section 112c integrally connecting the first and second sections. The first opening is partitioned by a partition part 112a2. Thus, it is possible to provide a thermoacoustic engine equipped with a high-temperature-side heat exchanger having a simple configuration and a low manufacturing cost.
