Description

Известны устройства дл  непосредственного измерени  величин тепловых потоков от нагретых поверхностей, состо щие из нагревательного элемента, установленного на изол ционной прокладке (эталонна  поверхность), источника питани  с регзл тором, термометров сопротивлени , нуль-прибора и измерител  потребл емого нагревателем тока, отградуированного в единицах теплового потока, величину которого определ ют по мощности, потребл емой нагревательным элементом при равенстве температуры нагревател  и исследуемой поверхности . Недостаток подобных устройств состоит в том, что теплопереходы от испытуемой поверхности и нагревательного элемента к воздуху неидентичны и тепловой поток не имеет резко выраженной направленности, что приводит к большим погрешност м измерени  величин тепловых потоков.Devices are known for directly measuring heat fluxes from heated surfaces consisting of a heating element mounted on an insulating gasket (reference surface), a regulator power source, resistance thermometers, a zero device and a meter consumed by the heater. heat flux, the value of which is determined by the power consumed by the heating element with equal temperature of the heater and the surface under study. The disadvantage of such devices is that the heat transfer from the test surface and the heating element to the air is not identical and the heat flux does not have a pronounced directionality, which leads to large errors in the measurement of heat fluxes.

В описываемом устройстве этот недостаток устранен применением вспомогательной высокотеплопроводной прокладки, отвод щей тепловой поток от изол ционной прокладки и не допускающей повыщени  температуры под датчиком.In the device described, this disadvantage is eliminated by the use of an auxiliary highly heat-conducting gasket that diverts heat flux from the insulation gasket and prevents temperature rise under the sensor.

На фиг. 1 схематически изображен датчик; на фиг. 2-принципиальна  схема устройства дл  измерени  тепловых -потоков.FIG. 1 schematically shows a sensor; in fig. 2 is a schematic diagram of a device for measuring heat fluxes.

Датчик устройства содержит изол ционную прослойку 1, служащую в качестве эталонной поверхности, на которой установлен нагревательный элемент 2 и измеритель 3 температуры этой эталонной поверхности. Второй измеритель 4 температуры служит дл  измерени  нагрева исследуемой поверхности, на которую устанавливают датчик . Изол ционна  прослойка 1, нагревательный элемент 2 и измерители 3 vi 4 температуры расположены в углублени х вспомогательной высокотеплопроводной прокладки 5, обеспечивающей идентичность теплоперехода к воздуху -как от исследуемой, так и от эталонной поверхности .The sensor of the device contains an insulating layer 1, which serves as a reference surface on which the heating element 2 is installed and the temperature gauge 3 of this reference surface. The second temperature meter 4 serves to measure the heating of the test surface on which the sensor is mounted. The insulating interlayer 1, the heating element 2 and the temperature measuring devices 3 vi 4 are located in the recesses of the auxiliary high-heat conducting gasket 5, which ensures the identity of the heat transfer to the air, from both the test surface and the reference surface.
