This article is devoted to the development of a universal cryo surface for cooling and further work with active samples of various compositions in the surface temperature range of 80 K – 300K. To build a computer model of a universal cryo surface, the finite element method was used, which has a deep theoretical justification and is used to solve a wide range of problems. range of tasks. In the work, a computer model of a universal cryo surface with automatic maintenance of a given temperature in the range from 80 K to 300 K was created, which is intended for efficient production, taking into account all possible wishes of the system user and solving a wide range of problems. In the course of the study, working drawings of the cryo surface were obtained, a computer model of a universal cryo plate was developed, and thermophysical processes in it were studied. Based on the created mesh of the model and the results of the consumption of the working cryo-liquid, the optimal temperature values of the cryo surface were determined. With the help of this development, the problems of innovative materials processing technologies will be solved when creating a heat exchanger and substrate, creating an efficient pump for cryo-liquid, as well as creating a temperature maintenance system of various accuracy. The result will be a system with compactness, versatility, and autonomy.
