N2 - With the development of science and technology and the continuous exploration of the deep universe, the heat dissipation capacity of space radiant coolant is required to be enhanced accordingly, which leads to the increasing mass of spacecraft and the decline of economy. Heat pipe technology is widely used in aerospace science and technology because it has good thermal conductivity and can realize fluid flow and heat transfer without external power. The alkali metal heat pipe radiator has the advantages of high thermal conductivity, strong anti-collision performance and strong single point failure resistance, which is unparalleled in other radiators. In this paper, finite difference method and iterative method are used to study the influence of fin width, inlet temperature, condensing length of heat pipe and other variables on the radiator weight, and the mechanism is analyzed. Using the analysis method of the combination of the first law and the second law of thermodynamics, the irreversible mechanical energy loss of the coolant in the coolant pipe is related to the entropy production, so as to further analyze the heat transfer characteristics of the two inlet - two outlet radiator.
