Description
Technical field
The present invention relates to a kind of determinator of coefficient of heat conductivity, particularly measures the determinator of the coefficient of heat conductivity of solid material.
Background technology
The coefficient of heat conductivity of material is an important parameter index of research material physical property, and in scientific research, teaching, the departments such as production all require to predict the coefficient of heat conductivity of material or survey.Coefficient of heat conductivity is the physical quantity of reflection material conducts heat performance, it is not only the foundation of the calorifics of evaluating material, and be the design considerations of material when applying, so the mensuration of the coefficient of heat conductivity of material is become to the key of exploitation new material in scientific experiment and engineering.
The coefficient of heat conductivity of current measurement material mainly contains following three kinds of methods:
One, laser shines method.What the method adopted is Transient Method, principle is that beam of laser is beaten at sample upper surface, by the temperature variation of infrared detector test lower surface, the actual data recorded are thermal diffusivities of sample, by with the density and the specific heat that obtain sample while standard model, the coefficient of heat conductivity of sample can be calculated by formula.The method advantage measures fast, adopts eyes with non-contact method, be applicable to high temperature, the sample of high heat conduction, but be not suitable for sandwich construction, coating, foam, liquid, anisotropic material etc.Reason be laser method test be thermal diffusivity, mathematic(al) mode is based upon on the basis of isotropic material.In addition, also need to record density with additive method, could convert as coefficient of heat conductivity, add the source of error.
Two, coefficient of heat conductivity method.What the method adopted is Transient Method equally, and principle utilizes thermal resistive materials---nickel makes the probe of a plane, simultaneously as thermal source and temperature sensor.The relation of the thermal resistivity of nickel and temperature and resistance is linear, and the change namely by understanding resistance can know the loss of heat, thus the heat conductivility of reflection sample.By recording the response time of temperature and probe, these characteristics of material can be calculated.Can directly obtain coefficient of heat conductivity and thermal diffusion coefficient by mathematical model, both ratio obtains volume specific heat.Advantage is quick, convenient, need not sample preparation especially, can be used for original position/one side test, be applicable to polytype samples such as solid, powder, liquid, coating, cellular material, but be subject to the restriction of detecting head surface coating, temperature range can only to 700 DEG C, and probe cost is higher, design is complicated, can not effectively promote.
Three, temperature gradient method.The method is placed between thermal source and cryogenic refrigerating unit by testing sample, when Temperature Distribution reach stable after, by measuring the parameters such as the heat flux that flows through sample and thermograde, calculate the coefficient of heat conductivity of material.Ideally, all heats of thermal source are passed to cryogenic refrigeration end by testing sample, in fact can inevitably shed from other direction by some heat, this inevitably causes there is thermograde in the xsect of same sample, thus cause measuring error, reduce the accuracy of measuring.Meanwhile, certainly exist thermal contact resistance at testing sample and between thermal source and cold junction, thus cause the inaccurate of measurement data.Therefore, the method measuring accuracy depends primarily on two aspects: on the one hand, how to reduce heat and sheds from other direction in transmittance process; On the other hand, thermal contact resistance is reduced.At present, from document both domestic and external, generally can use thermal insulation material as heat insulation layer in order to be hedged off from the outer world by thermal source, reduce the loss of heat as far as possible, but still have partial heat and outwards conduct, the precision how improving detection in this case becomes technical problem underlying.The theoretical foundation of the method is Fourier Heat Conduction law, described in (1).

measurement be the most difficult, other several amounts can directly be measured.
Under ideal conditions, namely determinator under adiabatic conditions, and the heating power of hot junction heating system is
size, but can inevitably shed from other direction by some heat in practical situations both, this inevitably causes there is thermograde in the xsect of same sample.
Meanwhile, certainly exist thermal contact resistance at testing sample and between thermal source and cold junction, thus cause the inaccurate of measurement data.
