technical field [0001] The invention belongs to the field of gravity circuit heat pipe design, in particular to a method for optimizing the operating temperature of a gravity circuit heat pipe system and a system design method. Background technique [0002] With the industrial demand of my country's building energy saving, especially the construction of data centers, the data center cooling technology with gravity loop heat pipe technology as the core has broad application prospects. The principle of the heat management technology of the gravity loop heat pipe is: the evaporator is connected to the heat source, and the heat generated by the heat source is transferred to the evaporator, so that the medium in the evaporator evaporates into steam. Driven by the density difference, the steam relies on the natural circulation driving force to rise into the condenser located in the external environment. The condenser releases heat to the external environment, and the working medi...
