Temperature control system of mechanical property test system for superconductor material

A temperature control system of a mechanical property test system for superconductor material relates to the measuring technology of the superconductor material, in particular to a temperature control system used in the measuring process of the superconductor material. The temperature control system comprises a temperature control box, an experimental box and a liquid nitrogen unit, wherein the experimental box adopts a double-layer space structure, one layer is connected with a liquid nitrogen tank and provided with a thermal compensation system electrically connected with the temperature control box, mechanical property test components and a temperature sensor are arranged on the other layer, and the temperature sensor is electrically connected with the temperature control box; and a liquid nitrogen thermocouple electrically connected with the temperature control box is arranged in the liquid nitrogen unit. The low temperature experimental box used in the mechanical property test for the superconductor material can provide a test environment with a wider range of temperature, and the temperature control system has the advantages of wide range of application, high measurement precision, low cost, and short test time.
