Study the environmental impact on mobile electronics in a heat-protective sewing shell

Abstract

The environment (Winter cold) affects both the individual and the equipment and communications needed to support workflow or general communication. Therefore, the issue of providing thermal conditions in which the communication device is located while a person stays in the cold is relevant. To protect such devices from premature cooling, they are placed in special parts of clothing. Model-ling and research of thermal insulation properties of garment parts for protection from cold of mobile communication devices will allow to establish effective parameters of thermal insulation structure. Such parameters will allow to develop and manufacture warm clothes with special details, which will maintain the performance and increase the time of stable operation of mobile communication devices necessary for a person in cold conditions. The geometrical model and the model mesh were developed. According to the results of numerical model-ling, the dependence of temperature in the thermal pocket on the ambient temperature was obtained, taking into account the presence or absence of the heating plate. The results of numerical modelling of model calculations al-lowed to theoretically justify by zoning and heating power the system of artificial thermoregulation in thermal protective clothing with integrated electronic devices.
