Description

Дл  определени  теплопроводности жидкой или газообразной среды примен ют устройства, содержащие эталонную стенку с известным термическим сопротивлением, по обе стороны которой расположены две проточных камеры, с тепловой изол цией от внешней среды и установленными внутри них термопарами.To determine the thermal conductivity of a liquid or gaseous medium, devices are used that contain a reference wall with a known thermal resistance, on both sides of which two flow chambers are located, with thermal insulation from the external environment and thermocouples installed inside them.

Предлагаемое устройство отличаетс  от известных устройств тем, что в нем применены рве дополнительных температуры, установленные на поверхности эталонной стенки. Такое выполнение устройства позвол ет одновременно с изменением коэффициента теплопроводности исследуемой среды определ ть ее коэффициент теплоотдачи.The proposed device differs from the known devices in that it utilizes a ditch with additional temperatures installed on the surface of the reference wall. Such an embodiment of the device allows simultaneously with a change in the thermal conductivity of the medium under study to determine its heat transfer coefficient.

На чертеже изображена пр-пнципиальна  схема предлагаемого уЬтрой.ства..The drawing shows the pr-pstsipialna scheme proposed by the U.

Ун:тройство выполнено в видеплоской эталонной стенки / с известным коэффициентом теплопередачи, по обеим сторонам которой расположены проточные камеры 2, Снабженные патрубками 5. По одной камере протекает жидкость .или ,газ, теплоотдачу которой требуетс  определить , а |по другой жидкость или газ ,с температурой, отличной от температуры вещества, протекающего в первой камере. Эталонна  стенка / и камеры 2 изолированы от внещнепо пространства с помощью термоизол ционного кожуха 4. В среднем .сечен.ии прибора в обеих камерах 2 установлены термопары дл  замера температуры протекающих по ним жидкостей или газов. Две дополнительных термопары устанавливаютс  на обращенных к этим камерам поверхност х эталонной стенки. В цел х достижени  большей точности опытных данных «гор чие спаи термопар можно .разместить на некотором .рассчэ нии по обеим сторонам от среднего .сечени  (АА)-внутри эталонной стенки. Термопары, установленные-внутри камер .2 и поверхности (или внутри) эталонной стенки, позвол ют измер ть коэффициент теплопроводности исследуемой среды и коэффиц ент теплоотдачи.Un: the triple is made in a video-flat reference wall / with a known heat transfer coefficient, on both sides of which flow-through chambers 2 are located. They are equipped with nozzles 5. A liquid flows through one chamber, or a gas, whose heat transfer needs to be determined with a temperature different from the temperature of the substance flowing in the first chamber. The reference wall / and chambers 2 are insulated from the external space by means of a thermal insulation casing 4. On average, thermocouples are installed in both chambers 2 to measure the temperature of liquids or gases flowing through them. Two additional thermocouples are mounted on the surfaces of the reference wall facing these chambers. In order to achieve greater accuracy of the experimental data, the “hot junctions of thermocouples can be placed on some calculation on both sides of the middle section (AA) —in the inside of the reference wall. Thermocouples mounted inside the chambers .2 and the surface (or inside) of the reference wall allow measuring the thermal conductivity of the test medium and the heat transfer coefficient.
