A thermoelectric couple and a capacitance probe are arranged in the organic glass tube, and the arrangement height of the thermoelectric couple and the arrangement height of the capacitance probe are similar. The lower part of the organic glass tube is provided with an electric heater. The utility model can determine the heat conductivity, the thermal diffusivity, the mass diffusion coefficient and the thermal mass diffusion coefficient, and the variance rule of the temperature and the humidity of the porous medium, and has the advantage of high measuring precision.
Description
The utility model relates to a kind of measurement mechanism that is used to measure thermophysical property, especially a kind of wet migrate attribute measuring instrument of wet porous medium heat that contains.
In the prior art, owing to lack the method and apparatus of measuring the inner local water capacity of porous medium, up to now, measuring method and measurement mechanisms such as " the integrating effect methods " that proposed, all be to be based upon on the wet group effect basis of moving of porous medium heat, thereby avoided the difficulty that moisture field is measured.But, because the wet migrate attribute of porous medium heat is subjected to the influence of temperature and humidity very big, and pass through the wet migrate attribute of " integrating effect method " designed heat is integral mean, be difficult to rule and inner link that the wet migrate attribute of reflect heat changes with temperature and humidity, be difficult to the wet transition process of heat of reflection porous medium inside, brought difficulty for the heat and mass transfer mechanism of further investigation porous medium inside.
Goal of the invention of the present utility model be to provide a kind of measuring accuracy high contain the wet migrate attribute measuring instrument of wet porous medium heat.
The utility model adopts following technical scheme to realize its goal of the invention:
The utility model is a kind of wet migrate attribute measuring instrument of containing of thermophysical property of wet porous medium heat that is used to measure, comprise organic glass infuser 1, outside organic glass tube 1, be provided with heat insulation layer 2, in organic glass tube 1, be provided with thermocouple 3 and capacitance probe 4, and being provided with of thermocouple 3 and capacitance probe 4 is highly similar, is provided with electric heater 5 in the bottom of organic glass tube 1.
Compared with prior art, the utlity model has following advantage:
1. the utility model can be measured the inner local water capacity of porous medium and temperature rule over time, thereby can determine that coefficient of heat conductivity, thermal diffusion coefficient, mass diffusivity and the caloic coefficient of diffusion of this porous medium and these characterisitic parameters with the Changing Pattern of temperature, humidity, have the high advantage of measuring accuracy.
2. monitor capacitance probe in the utility model, the distribution of electrical auxiliary heater and a plurality of thermocouple such as is provided with at the employing of technical measures, takes all factors into consideration the factor that thermophysical property parameter degree of accuracy is measured in influence, so further improved the accuracy of parameter measurement.
