発明の名称 (英語) THERMOACOUSTIC DEVICE
発明の概要(英語) A thermoacoustic device capable of generating a sound wave in a shortened time and having a greatly improved energy conversion efficiency. The thermoacoustic device (1) comprises a pair of heat exchangers (41, 43) installed on the high- and low-temperature sides respectively, a second stack (42) installed between the heat exchangers (41, 43) and each having a conduction passage inside itself, and a loop tube (2) equipped with the heat exchangers (41, 43) and the stack (42). The sound energy generated in the loop tube (2) by a sound wave generator (3) is converted into heat energy by using the heat exchangers (41, 43) and the stack (42). A narrow part (21) whose inner diameter is relatively small is provided in a position where the sound particle velocity of the standing wave produced in the loop tube (2) takes on a maximum value. A branch tube (2e) for decreasing the sound particle velocity is connected to a position where the sound particle velocity of the standing wave produced in the loop tube (2) takes on a minimum value.
