The invention relates to the field of underwater exhaust and noise reduction, and provides a small underwater thermodynamic vehicle microbubble resistance and noise reduction device which comprises a microbubble generation film, the microbubble generation film is installed on a pressure-resistant cylindrical shell of an underwater vehicle through a microbubble generator conformal structure frame, and long-strip-shaped holes are formed in the surface of the microbubble generation film. The long edge of the long-strip-shaped hole is perpendicular to the navigation axis, gas distribution holes are formed in the underwater navigation body pressure-resistant cylindrical shell and used for communicating gas distribution header pipes in the underwater navigation body pressure-resistant cylindrical shell with all the microbubble generation films, and high-temperature waste gas of the high-pressure external combustion type thermal power device is distributed into the lower gas distribution header pipe and the upper ga
