The working flow of the power generation heat-exhaust unit is as follows:

when the thermoacoustic power generation subsystem 110 works, the heat pipe 30 brings the heat of the reactor core out of the low-temperature gas transferred to the heat pipe heat exchanger 100, the gas in the inner layer area of the heat pipe heat exchanger 100 absorbs heat to become high-temperature gas, the high-temperature gas becomes a heat source of the thermoacoustic power generator, the high-temperature gas flows through the hot end heat exchanger 325 of the thermoacoustic power generator 300 to become a high-temperature end sequentially through the outlet flow passage of the inlet and outlet separation connecting pipe and the electromagnetic valve, and the high-temperature waste heat gas flows to the active waste heat discharge heat exchanger 120 of the active waste heat discharge system to exchange heat and cool to form cold source gas, and the temperature is about 300K.
