a thermoacoustic engine

Abstract

The present invention relates to the technical field of thermoacoustic heating equipment, and discloses a thermoacoustic engine, which includes at least one thermoacoustic starting unit, and the thermoacoustic starting unit includes a main water cooler, a regenerator and a nuclear fuel heater connected in sequence; The nuclear fuel heater is used for heat exchange between the nuclear fuel reaction and the working gas flowing through the nuclear fuel heater, so as to increase the temperature of the working gas. The thermoacoustic engine solves the problems of complex energy transmission, low thermal energy grade, and large system in the process of nuclear reactor thermal energy utilization, and at the same time solves the problem that the external heating thermoacoustic engine heater is difficult to achieve ultra-high temperature and ultra-high heat flux heat exchange. Provide a new way of nuclear energy utilization, while improving the efficiency and safety of nuclear energy utilization, the system is more compact.

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 ...
