Description

Основанный на принципе дополниTej bHoft стенки Хенки тепломер Шмидта,  вл ющийс  прибором дл  измерени  теплового потока через поверхность, имеет тот недостаток, что ко: фициент теплопроводности резины современен измен етс , вследствие чего показани  прибора современем станов тс  неверными .Based on the principle of the additional bHoft wall, the Hencky Schmidt heat meter, which is a device for measuring the heat flux through the surface, has the disadvantage that the thermal conductivity of rubber is modernized, as a result of which the device’s indication has become incorrect.

С целью устранени  указанного недостатка предлагаетс  в качестве теплоизолирующего сло  прибора использовать газ, заключенный между двум  теплопроводными пластинами, снабженными каналами дл  вставлени  термометров .In order to eliminate this drawback, it is proposed to use gas enclosed between two heat-conducting plates with channels for inserting thermometers as a heat-insulating layer of the device.

На чертеже изображен предлагаемый прибор в поперечном разрезе.The drawing shows the proposed device in cross section.

Прибор состоит из двух алюминиевых дисков /, 2, между которыми заключен слой газа посто нной толщины с посто нным коэфициентом теплопроводности , не измен ющимс  со временем. Дл  уменьшени  вли ни  на показани  прибора бокового теплообмена слой газа разделен концентрическими кольцами 5,5 из пластмассы, а самые диски 1,2 разрезаны на концентрические кольца 7, зазоры 8 между которыми заполнены теплоизол ционной мастикой. Диски 1,2 ст нуты друг с другом желобчатымThe device consists of two aluminum disks 2, between which a layer of gas of constant thickness is enclosed with a constant coefficient of thermal conductivity, which does not vary with time. To reduce the influence of the lateral heat exchange device, the gas layer is divided by concentric rings 5.5 made of plastic, and the disks 1,2 themselves are cut into concentric rings 7, the gaps 8 between which are filled with insulating mastic. 1.2 discs chickpeas grooved with each other

по сом 4 и снабжены каналами 5, 6 дл  вставлени  термометров, в качестве которых могу быть применены ртутные термометры , термопары и т. п. Указанные термометры служат дл  измерени  температурного перепада по обе стороны сло  газа и по разности температур в дисках 7, 2 определ етс  величина4 and equipped with channels 5, 6 for insertion of thermometers, which can be used as mercury thermometers, thermocouples, etc. These thermometers are used to measure the temperature difference on both sides of the gas layer and the temperature difference in the disks 7, 2 value

TenJnoBoro потока q по уравнению:TenJnoBoro flow q by the equation:

q . где ti - 2 разность температур , а w - известное термическое сопротивление сло  газа. Вместо двух термометров дл  измерений может быть применен один диференциальный термометр , градуированный непосредственно в калори х теплового потока.q. where ti - 2 is the temperature difference, and w is the known thermal resistance of the gas layer. Instead of two thermometers, one differential thermometer can be used for measurements, graduated directly in calories of heat flux.

Предмет изобретени .The subject matter of the invention.

Прибор дл  измерени  величины теплового потока через поверхность.Instrument for measuring the heat flux through the surface.

основанный на принципе дополнитель- ; ной стенки Хенки, отличающийс  тем,, что, с целью получени  независимости коэфициента теплопроводности прибора от времени, теплоизол ционный слой прибора образован слоем газа, заключенного между двум  теплопроводными пластинами, снабженными каналами.дл  вставлени  термометров.based on the supplementary principle; The Hanky wall, characterized by the fact that, in order to obtain the independence of the thermal conductivity coefficient of the device from time to time, the thermal insulation layer of the device is formed by a layer of gas enclosed between two heat-conducting plates equipped with channels for inserting thermometers.
