Abstract

The problems of intensification of conditions for heat exchange in « liquid- to-air» refrigerating systems on the basis of heat dissipating elements with spiral-wire finning are considered. The analytical correlations for the calculation and optimization of such systems are presented. Based on the investigations a high efficiency air heat exchanger with the dissipated capacity up to 16 kW has been designed. The design of self-contained refrigeration system for powerful gas lasers as used in medical apparatuses for diagnostics of cancer diseases, in show-business and in a number of devices operated in mobile objects is described.
