Description
(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ КОЭФФИЦИЕНТА ТЕРМО-Э.Д.С.(54) DEVICE FOR MEASURING THERMO-EDS FACTOR
Это достигаетс тем, что оба блока выполнены неподвижными и в каждом блоке расположены подпружиненные, свободно перемещающиес стержни из термоэлектропроводного материала, которые контактируют с образцом торцами, выполненными в виде сферы.This is achieved by the fact that both blocks are made stationary and in each block there are spring-loaded, freely moving rods of thermo-electrically conductive material, which are in contact with the sample with the ends made in the form of a sphere.
На чертеже изображено предлагаемое устройство .The drawing shows the proposed device.
Оно состоит из двух блоков 1 и 2, которые выполнены неподвижными.It consists of two blocks 1 and 2, which are made stationary.
В каждом блоке расположены подпружиненные , свободно перемещающиес стержни 3 из хорощо провод щего тепло и электрический ток материала и наход щиес в тепловом контакте с блоками , что достигаетс высокой степенью чистоты обработки поверхностей стержней и блоков и специальной термопроводной смазкой, например, КПТ-08.In each block, spring-loaded, freely moving rods 3 are made of well-conducting material that is in heat and electrical current and are in thermal contact with the blocks, which is achieved by a high degree of surface cleaning of the rods and blocks and special thermal-conductive grease, for example KPT-08.
Блоки заполнены рабочим теплом, в качестве которого можно использовать воду, сплав Эп-йа, The blocks are filled with working heat, which can be used as water, an ESP-ya alloy,
1.40 и другие вещества.1.40 and other substances.
Между стержн ми помещают провер емые образцы 4.Test pieces 4 are placed between the rods.
К блокам прижаты термоэлектроЗатареи с теплообменниками . Блоки имеют нодвижную стенку 6 с микропереключател ми 7 дл подключени источников 8 к термоэлектробатаре м 5.Thermal batteries with heat exchangers are pressed to the blocks. The blocks have a fixed wall 6 with microswitches 7 for connecting sources 8 to a thermoelectric cell 5.
Источники питани 8 подключены к термоэлектробатаре м так, что блок 1 охлаждаетс , а блок 2- нагреваетс . Увеличение объема рабочего тела измен ет положение подвижной стенки 6, разрыва цепь питани термоэлектробатарей 5 от источнико 8. Вследствие теплообмена с окружающей средой рабочее тело измен ет свое агрегатное состо ние, цепь питани термоэлектробатарей вновь замыкаетс и процесс повтор етс . За счет этого температураThe power sources 8 are connected to the thermoelectric generator so that the unit 1 is cooled and the unit 2 is heated. Increasing the volume of the working fluid changes the position of the movable wall 6, breaking the supply circuit of thermoelectric batteries 5 from the source 8. Due to heat exchange with the environment, the working medium changes its state of aggregation, the supply circuit of the thermoelectric batteries again closes and the process repeats. Due to this temperature
стернсней в блоках поддерживаетс посто нной с высокой точностью.Sterns in blocks is kept constant with high precision.
Исследуемые образцы 4 привод тс в тепловой и электрический контакты со стержн ми, а так какThe test samples 4 are brought into thermal and electrical contact with the rods, and since
торцы стержней вьшолнены сферическими, то контакт осуществл етс в одной точке и, следовательно , повышаетс точность измерений.the ends of the rods are spherical, then the contact is made at one point and, consequently, the measurement accuracy is improved.
Возникающа термо-э-д.с. регистрируетс выходным прибором 9, который может быть отградуирован в величинах коэффициентов термо-э.д.с .The emergence of thermo-e. recorded by the output device 9, which can be calibrated in terms of the coefficients of thermo-emf.
Кроме того, дл измерени коэффициента термо-э ,д.с, полупроводников различной высоты, используемых в практике термоэлектрического приборостроени , нет необходимости измен ть дл In addition, to measure the thermoelectric coefficient, ds, semiconductors of different heights, used in the practice of thermoelectric instrumentation, there is no need to change for
каждого случа рассто ние между блоками за счет того, что стержни имеют возможность перемещатьс относительно неподвижных блоков.In each case, the distance between the blocks is due to the fact that the rods are able to move relative to the fixed blocks.
