The invention provides an energy-saving environment-friendly layout of a large-scale routine hypersonic wind tunnel. The system comprises a gas tank, a heater, a stabilization segment, a jet pipe, a test segment, an ultra-expanding segment and a heat exchanger, wherein the stabilization segment, the jet pipe, the test segment and the ultra-expanding segment are successively connected to form a major test wind tunnel assembly, the heat exchanger comprises an intermediate channel and a peripheral channel encircling the intermediate channel, an outlet of the ultra-expanding segment communicates with the intermediate channel of the heat exchanger, the gas tank communicates with the peripheral channel of the heat exchanger, and high-pressure gas in the gas tank is sent into the heater via the peripheral channel of the heat exchanger by means of a gas pipeline, then is sent into the stabilization segment after passing through the heater and is discharged through flowing through the intermediate channel of the heat
