Beschreibung
Zusammenfassung:	The invention discloses a cooling air entraining system and method, the cooling air entraining system comprises a cooling passage, the cooling passage is a closed passage, and the closed passage can transmit cooling air generated by a cold air source generation device to a hot end component needing to be cooled through the passage in sequence; the cooling passage is located in a center closed area of the large system, the cold air source generating equipment is a gas compressor, the hot end component is a turbine wheel disc, the cooling passage comprises an intermediate shaft sleeve, cooling gas is led to a wheel disc center hole from the gas compressor radial air-entraining wheel disc, passes through the intermediate shaft sleeve along each stage of center hole after air-entraining, and then enters the turbine wheel disc center hole; and the temperature is conveyed to a hot end component or a cavity needing to be cooled from a central hole of the turbine wheel disc, so that the temperature of the turbine hot
