STUDY OF THE TECHNOLOGY FOR FORMATION OF THERMAL CONTACT SURFACES OF HEAT AND MASS TRANSFER PROCESS INTENSIFIERS

Abstract

The development of scientific and technological progress in recent decades has led to an increase in the consumption of natural energy carriers. This in turn affects mineral deposits – they are being depleted. In order to reduce energy consumption, the issue of energy conservation is relevant. One of the ways to solve this problem is to conduct research in the field of improving the efficiency of energy technology equipment with the subsequent development of universal technology and equipment for the intensification of heat and mass transfer processes. This article presents the most currently used methods of intensification of heat exchange processes, their advantages and disadvantages. In addition, the most promising method is determined. The technology of forming a thermocontact (discretely rough) surface on a metal sheet is described. Expressions for determining the effort required to produce this surface under various conditions are defined. A method of experimental research and a tool for manufacturing a thermocontact surface are presented. As a result of experimental studies, it is found that, depending on the conditions of formation of the thermal contact surface, the analytical solution differs from the experimental values by 5.3–13.4 %. Another important factor affecting the shaping is the feed rate of the metal sheet, its optimal value is 1000–2000 mm/min.
