Regenerative Heat Exchanger Based on Graphene-Modified Paraffin for Portable Respiratory Devices

Abstract

The present paper describes an investigation of the application of the carbon nanostructures-and graphene-modified paraffin for the heat exchange elements of means of individual protection. The thermophysical parameters of the modified material and the test benches in the mode of periodical alternation of temperature, when the oxygen with high temperature up to 250°C is produced in the cartridge (with powdered potassium superoxide) and СО2 at 36 оС is arrived from the artificial lung device, were studied.The application of graphene as the modifiers of heat storage materials for the individual protection means of respiratory organs makes it possible to improve cooling efficiency by 25-40°С to create the comfortable conditions for breathing.
