Description

technical field [0001] The invention relates to the technical field of thermoacoustic heating equipment, in particular to a thermoacoustic engine. Background technique [0002] In traditional nuclear power generation systems, the nuclear reactor is usually used as an independent system to generate heat, and the heat transfer medium (high-pressure water in pressurized water reactors, metal sodium in sodium-cooled reactors, and high-pressure helium in gas-cooled reactors) will The heat in the nuclear reactor is sent to the thermal power conversion system—the steam turbine, which is then connected to the engine to output electric energy. The nuclear reactor of this nuclear power generation system requires a very complex active heat exchange device to prevent the nuclear reactor from melting and leakage accidents; the heat output from the nuclear reactor has a low temperature, which is not conducive to the high thermodynamic efficiency of the thermal power conversion system; in ...
