Inter aeroengine cold or cold room layout regenerative cycle

Inter aeroengine cold or cold room regenerative cycle layout, including the main flow path Brayton Cycle, also includes a supercritical fluid circulation, two loops independent of each other, through small-scale heat exchanger coupled. Small-scale heat exchanger uses a small-scale supercritical fast compact heat exchangers, heat exchanger comprises a heat exchanger components and two kinds of refrigerants, were both working fluid through the heat exchanger element, wherein: one of the working fluid supercritical fluid state, and the other working fluid is not limited to, the size of small-scale heat exchanger components genus category, the supercritical state of the fluid pressure above the critical pressure of at least 0.5MPa, the temperature is above the critical temperature of at least 200 degrees geometric dimension, said minor dimension refers to the basic unit of the heat exchanger is not more than 2 mm. The present invention effectively overcomes the disadvantages of the conventional cold room or cold room regenerative cycle layout, improve circulation efficiency of the engine, reducing fuel consumption.
