Example Embodiment
[0020] The present invention will be further described below in conjunction with specific embodiments.
[0021] A double-layer liquid-absorbing core non-opening high-efficiency cooling turbine guide vane device includes a turbine guide vane device and a double-layer liquid-absorbing core hot plate. The turbine guide vane device includes a diaphragm outer ring 1, a turbine blade 2, a stator blade holding ring 3, and fins 4. The turbine blade 2 is an evaporation section, and the stator blade holding ring 3 is a condensing section. The diaphragm outer ring 1 is fixed on the upper surface of the turbine blade 2. The fin 4 is a rectangular parallelepiped groove structure. The stator blade holding ring 3 is a hollow structure, the upper surface of the stator blade holding ring 3 has an opening, and the outer edge of the opening is fixed to the lower surface of the turbine blade 2, and the stator blade holding ring 3 communicates with the interior of the turbine blade 2 through the upp...
