К решению задачи конструирования измерителя теплопроводности теплоизоляционных материалов

Abstract

Рассмотрены вопросы конструирования измерителя теплопроводности теплоизоляционных материалов. Предложены различные варианты исполнения составных элементов прибора. Разработаны и изготовлены три способа компоновки (три конструктивные модели каркаса) измерителя теплопроводности. Выбранная симметричная схема измерителя исключает необходимость использования в приборе тепломера, являющегося достаточно проблематичным измерительным средством. Проведенные испытания показали удовлетворительную надежность и приемлемую точность измерителя теплопроводности. Указывается на наличие положительного опыта использования измерителя в лабораторном практикуме и при выполнении ряда научно-исследовательских работ. Измеритель пригоден также и для измерения термического сопротивления теплопроводности образца, в том числе и многослойного. The problems of constructing thermal conductivity meter for thermal insulating materials are considered in the article. Different versions of the constituent elements of the device are given. Three ways to assemble thermal conductivity meter (three structural model of a framework) are worked out and produced. Selected balanced circuit of the meter eliminates the need for heat meter in the instrument, which is quite problematic measurement means. The tests show satisfactory reliability and acceptable accuracy of thermal conductivity meter. Positive experience of the use of the meter in the laboratory and a number of scientific and research work is indicated. The meter is also suitable for measuring thermal resistance of the thermal conductivity of the sample, including a multilayer one.
