Изобретение относитс к испытательной технике, в частности, к устройствам дл определени теплофизических характеристик жидкостей.The invention relates to a test apparatus, in particular, to devices for determining the thermophysical characteristics of liquids.
Известны устройства дл определени теплофизических характеристик материалов, содержащие термостатируемый корпус, в который помещаетс бокс с образцами, схему измерени температуры и устройство дл регистрации времени измерени температуры 1.Apparatuses for determining the thermophysical characteristics of materials are known, comprising a thermostatted housing in which a sample box, a temperature measuring circuit and a device for detecting the temperature measuring time 1 are placed.
Недостатком этих устройств вл етс необходимость длительного термостатировани образца и низка точность получаемых результатов .The disadvantage of these devices is the need for prolonged temperature control of the sample and the low accuracy of the results obtained.
Наиболее близким к изобретению вл етс устройство, обеспечивающее определение теплофизических характеристик жидкостей (коэффициент теплопроводности) по методу двух температурно-временных интервалов, которое содержит нагреватель посто нной температуры с одним из спаев термопары, кювету дл жидкостей с известными (реперна жидкость) и исследуемыми теплофизическими свойствами, выполненную в виде цилиндра с дном из материала высокой теплопроводности, и опоры дл The closest to the invention is a device that determines the thermal characteristics of liquids (thermal conductivity coefficient) by the method of two temperature-time intervals, which contains a constant temperature heater with one of the thermocouple junctions, a cuvette for liquids with known (reference fluid) and thermal properties studied. , made in the form of a cylinder with a bottom of a material of high thermal conductivity, and supports for
теплоприемника в виде кольца; теплоприемник цилиндрической фор.мы, установленный на опоре жидкости, снабженный вторым спаем термопары, установленным на его торцовой поверхности и- соприкасающимс с исследуемой средой; регистрирующий гальванометр 2.heat receiver in the form of a ring; a heat receiver of a cylindrical shape, mounted on a liquid support, equipped with a second junction of a thermocouple mounted on its end surface in contact with the test medium; recording galvanometer 2.
Недостатком данного устройства вл етс снижение точности получаемых результатов , так как при последовательном измерении разности относительных температур дл реперной и исследуемой жидкости трудно создать одинаковые услови проведени опыта, и больща длительность испытаний.The disadvantage of this device is a decrease in the accuracy of the results obtained, since when measuring the difference in relative temperatures for the reference and the test liquid, it is difficult to create the same conditions for the experiment and the longer the test.
Цель изобретени - повышение точности определени испытаний теплофизических характеристик и сокращени времени проведени испытаний.The purpose of the invention is to improve the accuracy of determining the tests of thermophysical characteristics and reducing the time of testing.
