Abstract
A multifunctional C4F7N/CO2 mixed gas preparation system is disclosed. The C4F7N heat exchanger is used to heat and vaporize C4F7N input through the C4F7N input port; the CO2 heat exchanger is used to heat and vaporize CO2 input through the CO2 input port; the C4F7N/CO2 mixing pipeline structure is used to mix the heated C4F7N and heated CO2, and the C4F7N/CO2 mixed gas output pipeline structure is used to output the C4F7N/CO2 mixed gas. The C4F7N/CO2 mixing pipeline structure comprises a C4F7N/CO2 dynamic gas preparation pipeline structure and a C4F7N/CO2 partial pressure mixing pipeline structure; the C4F7N/CO2 partial pressure mixing pipeline structure includes partial pressure mixing tanks for mixing the CO2 and the heated C4F7N of certain pressures; and a plurality of partial pressure mixing tanks are arranged in parallel. A multifunctional C4F7N/CO2 mixed gas preparation method is also disclosed.
