Description

Предметом изобретени   вл етс  прибор дл  определени  тепловых характеристик термически изотроппых материалов, выполненный в виде двух коаксиально расположенных цилиндров с центральным нагревательным приспособлением, образующих кольцевое пространство дл  испытуемого материала, в котором размещены термопары дл  измерени  температуры .The subject of the invention is a device for determining the thermal characteristics of thermally isotropic materials, made in the form of two coaxially arranged cylinders with a central heating device, forming an annular space for the test material in which thermocouples are placed to measure the temperature.

Предлагаемый прибор позвол ет производить одновременное определение температуропроводности, теплопроводности и теплоемкости материалов .The proposed device allows simultaneous determination of thermal diffusivity, thermal conductivity and heat capacity of materials.

Особенность прибора заключаетс  в том, что гор чие спаи установленных в кольцевом пространстве термопар расположены в одной горизонтальной плоскости, с целью замера теплового перепада в точках как на наружной поверхности внутреннего цилиндра, так и на внутренней поверхности наружного цилиндра, а также внутри исследуемого материала .The peculiarity of the device is that the hot junctions of thermocouples installed in the annular space are located in the same horizontal plane in order to measure the thermal differential at points on the outer surface of the inner cylinder and on the inner surface of the outer cylinder, as well as inside the material under study.

Дл  устранени  утечки тепла с торцевых сторон прибора установлены теплоизол ционные прокладки, а дл  повыщени  точности измерени  электронагревательный элемент и термопары наход тс  под действием установленных на торцевых сторонах цилиндров подпружиненных приспособлений , поддерживающих линейность расположени  электронагревательного элемента и термопар внутри цилиндров .To eliminate heat leakage, heat insulating gaskets are installed on the end sides of the device, and to improve the measurement accuracy, the electric heating element and thermocouples are under the action of spring-loaded devices on the cylinder side surfaces that maintain the linearity of the electric heating element and thermocouples inside the cylinders.

На чертеже предлагаемый прибор изображен в двух проекци х.In the drawing, the proposed device is shown in two projections.

Прибор состоит из двух удлиненных коаксиальпо расположенных цилиндров 1 и 2, кольцевое пространство между которыми образует камеру дл  помещени  исследуемого материала 3. Прибор с торцевых сторон закрыт крыщками 4 с прокладками из теплоизол ционного материала .The device consists of two elongated coaxially arranged cylinders 1 and 2, the annular space between which forms a chamber for placing the material under study 3. The device is closed on its end sides by flaps 4 with gaskets of thermally insulating material.

По оси впутреннего цилиндра 2 установлено электронагревательное приспособление 5.The axis of the inner cylinder 2 is installed electric heating device 5.

Замер температур поверхностей цилиндров 1 к 2 и внутри исследуемого материала 5 производитс  термопарами 6, гор чие спаи которых размещаютс  в одной горизонтальной плоскости в средней части прибора .The temperature measurements of the surfaces of the cylinders 1 to 2 and inside the material under study 5 are made by thermocouples 6, the hot junctions of which are located in the same horizontal plane in the middle part of the device.

Центральное расположение электронагревательного приспособлени  5 и расположепие гор чих спаев термопар па определенном рассто The central location of the electric heater 5 and the location of the hot junctions of thermocouples at a certain distance
