Design method for low-temperature loop heat pipe working medium filling amount and gas reservoir volume

The invention provides a low-temperature loop heat pipe working medium filling amount and gas reservoir volume design method, which comprises the following steps of: establishing an equation of the working medium filling amount under the lowest-temperature working condition and the volume and the liquid content of each vapor-liquid channel, determining the working medium filling amount under the lowest-temperature working condition according to a set initial volume value of a gas reservoir, and calculating the volume of the gas reservoir according to the determined working medium filling amount. The working medium filling amount under the working condition of the lowest temperature is the same as the working medium filling amount under the working condition of the highest temperature, and the mass of the gaseous working medium under the working condition of the highest temperature is calculated according to the working medium filling amount under the working condition of the lowest temperature; calculating th
