A temperature control method and system applied to a hot vacuum test

Abstract

The application relates to the technical field of temperature control, and discloses a temperature control method and system applied to a hot vacuum test, the temperature control method applied to the hot vacuum test comprises the following steps: establishing a structure mapping of a temperature control area to be controlled and a nested visual leakage cavity; updating an opening area and a side wall area of a visual leakage channel; calculating a non-local reachable rate; synthesizing an equivalent non-local radiation boundary; calculating a radiation potential anchor point; calculating a migration type reference temperature; and calculating and executing heating power. Through the establishment of the structure mapping of the temperature control area to be controlled and the nested visual leakage cavity, the geometric parameter changes of the visual leakage channel caused by cold shrinkage are updated in real time, the actual radiation transmission capacity of the visual leakage channel is quantified, the equivalent radiation boundary capable of integrating local and non-local influences is synthesized, the migration type reference temperature dynamically adjusted with the boundary is obtained through the fixed radiation potential anchor point, and finally the heating power is calculated by comprehensively considering various thermal influence factors, so that the stability of the temperature control of the hot vacuum test is guaranteed.
