▎ 摘　　要

NOVELTY - The device has a condensing main machine provided with a shell (1). A condensing pipe is connected with a spiral section and a gas-liquid separating section, where the condenser pipe is made of graphene material. A top portion of the spiral section is provided with an air inlet (21). An air outlet at a bottom end of the spiral section is connected to the gas liquid separating section, where top and bottom portions of the gas fluid separating section are respectively provided with exhaust holes (23) and liquid discharge holes (24). The exhaust hole is located above the air outlet. The liquid discharge hole is positioned below the air outlet. A flexible refrigerating sheet is arranged between the condensing pipe and a radiator. A hot surface of a flexible cooling sheet is attached to the radiator. The condensation main machine is provided with a spray head. A spraying water circulation system is used to circulate water sprayed from the spray head to the spray head. USE - Condensing device for cooling earthquake precursor observation hot spring well gas in underground fluid earthquake precursor monitoring application. ADVANTAGE - The flexible refrigerating sheet is provided with two pieces, respectively is installed on the middle upper part and middle lower part of the spiral section of the condensing pipe. The condensing device has good cooling effect. The corrosion resistant, low adsorption of polytetrafluoroethylene film is used as the inner film of the pipe, reducing the pipe pipeline to absorb the gas, improving the measuring precision. The gap between the pipe and the radiator is filled by the thermal insulation cotton. The friction resistance of the spraying water and the pipe is increased to greatly improve the cooling effect, by increasing the cooling gas path. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a condensing device. Shell (1) Display panel (7) Air inlet (21) Exhaust holes (23) Liquid discharge holes (24)
