Abstract: In the design scheme, the isothermal design realized by heat pipe technique and high-efficiency heat conductance material technique is explained in details. Addtionally, on the basis of the two techniques, the equivalent heat conductance coefficient of the porthole flange in different heat transfer direction is analyzed. Finally, a mathematical model of the characteristic heat transfer process of the porthole is provided as the spacecraft operates in orbit, and its simplified analytical solution is presented.
