Description
Изобретение относитс к области теплофизических измерений и может быть использовано дл определени коэффициентов теплопроводности широкого круга материалов во многих отрасл х народного хоз йства дл контролировани качества материалов и изделий.The invention relates to the field of thermophysical measurements and can be used to determine the thermal conductivity of a wide range of materials in many areas of the national economy to control the quality of materials and products.
Известиы устройства дл измерени коэффициента теплопроводности, в состав которых вход т нагреватели посто нной мощ,постн и датчики температуры 1.The device for measuring the coefficient of thermal conductivity, which includes constant power, post heaters and temperature sensors 1.
В одной модификации образцы вынолнены в виде квадратных плит. Плиты укладываютс одна на другую. Между плитами устанавливаютс одинаковые по мощности плоские тонкие нагреватели. В плите испытуемого материала и в нагревател х устанавливаютс дифференциальные термопары. Дл измерений с применением такого устройства требуютс образцы строго определенной формы и размера. Недостатком этого устройства вл етс длительцость эксперимента.In one modification, the samples are made in the form of square plates. The plates are stacked one on top of the other. Between the plates, flat thin heaters of equal power are installed. Differential thermocouples are installed in the test material plate and in the heaters. For measurements using such a device, samples of a strictly defined shape and size are required. A disadvantage of this device is the duration of the experiment.
Ближайшим к изобретению техническим решением вл етс устройство дл измерени коэффициента теплопроводности, включающее зонд с нагревателем посто нной мощности. Зонд представл ет собой металлическую коробку, заполненную опилками и кусочками меди, с наклеенной на нееThe closest technical solution to the invention is a device for measuring the coefficient of thermal conductivity, including a probe with a constant power heater. The probe is a metal box filled with sawdust and pieces of copper, glued to it.
