CRYOGENIC FLUID BODY COOLING SYSTEM IN THERMOMECHANICAL SIMULATORS

摘要

Abstract The invention relates to a cryogenic fluid specimen cooling system in thermomechanical simulators. The present invention relates to a cryogenic fluid specimen cooling system in thermomechanical simulators, which can be used in gleeble® thermomechanical simulators, allowing internal cooling. and external of specimens by cryogenic cooling fluids, preferably liquid nitrogen. The device is versatile for cooling specimens of different geometries and shapes, and keeps specimens at constant temperatures for long test times ensuring efficient cooling and enabling simulations under controlled conditions at temperatures below ambient and temperatures below 0 ° C. ° c, with variable cooling rates that can reach a maximum of 170 ° c / s.
