HEAT TRANSPORT DEVICE AND FURNACE

WIPO Patent Application WO/2024/075356

A1

[Problem] To simultaneously achieve the following goals in a heat transport device that uses thermoacoustic self-excited oscillation. (A) Increase the heat transport quantity during heat transport that uses self-excited oscillation. (B) Make it possible to adjust the heat transport quantity. (C) Increase the serviceability of the heat transport device. [Solution] A heat transport device (1) according to the present invention uses thermoacoustic self-excited oscillation and comprises a container (11) that can be provided so as to span between the interior and the exterior of a high-temperature heat source (for example, a furnace (F)) and has, in the interior thereof, a pipe passage (11P) in which both end sections (first end section (11E1), second end section (11E2)) can be substantially blocked. The interior of the pipe passage (11P) can have a working fluid enclosed therein. A pressure control means (15) that can control the pressure of the working fluid is further provided. The pressure control means (15) has a first pressure control part that can control the pressure of the working fluid such that a thermal accumulator (13) weakens self-excited oscillation in response to a command to reduce the heat transport quantity, and a second pressure control part that can control the pressure of the working fluid such that the thermal accumulator (13) strengthens self-excited oscillation in response to a command to increase the heat transport quantity.
