The utility model has the advantages of simple structure, convenience and practicality and can be used for testing the heat conductivity of materials in fields such as industry, agriculture, building material, scientific research, teaching, etc.
Description
The utility model belongs to the physical measurement techniques field, particularly belongs to a kind of thermal conductivity to all kinds of heat conductors and carries out the instrument that accurate quantification is measured.
The thermal conductivity of material is an important parameter of exosyndrome material thermodynamic property.The instrument of domestic present measurement thermal conductivity or cost an arm and a leg, otherwise it is low to measure temperature, and error is big.The thermal conductivity measuring instrument that Xi'an Educational Instrument Factory produces can only be surveyed the material thermal conductivity of fixed measure under the normal temperature, and the scope of application is very limited, and this instrument thermometric uses is general thermometer, and error is bigger.
The purpose of this utility model provides a kind of material thermal conductivity of surveying multiple shape, size under normal temperature and the high-temperature condition, and the high measuring instrument of measuring accuracy.
The utility model is made up of heat supply end, heat absorbing end and casing.In the middle of heat supply end and heat absorbing end were stuck in detected materials, single unit system was placed in the casing that thermal insulation material is housed.Have steam (vapor) outlet and steam inlet on the heat supply end shell, inside and outside two-layer asbestos gauge is housed in the heat supply end, heating wire is on the internal layer asbestos gauge; Have liquid inlet and liquid outlet on the heat absorbing end shell, the heat absorbing end internal fixation has spreader plate, and the heat absorbing end outside is stained with heat-insulating block, and heat-insulating block is connected with the screw mandrel sleeve with screw mandrel, and the screw mandrel sleeve is fixed on the casing, and handwheel is equipped with in the screw mandrel outer end.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of heat supply end.
As shown in Figure 1, heat supply end I and heat absorbing end III are separately fixed at the two ends in the casing, and the detected materials II is stuck between heat supply end I and the heat absorbing end III.Have steam inlet 7 in heat supply end shell 13 upper ends, the lower end has steam (vapor) outlet 8, internal layer asbestos gauge 21 and outer asbestos gauge 12 are housed in the heat supply end, as shown in Figure 2, heating wire 11 is on internal layer asbestos gauge 21, can make heat supply end keep 100 ℃ by steam, be used to survey the material thermal conductivity under the normal temperature; Then can make the heat supply end temperature reach hundreds of degree centigrade, the thermal conductivity of material when being used to measure high temperature by heating wire.Be not with holes 5 and aperture 6 in 1/4th places, the left side of detected materials II and the right 1/4th punishment, draw thermocouple lead 1 from aperture 5, draw thermocouple lead 2 from aperture 6, the degree of depth of aperture 5 and aperture 6 can reach the material center, and the size in hole is for can just hold the thermopair solder joint.Can accurately measure the temperature of material diverse location by thermopair.The two ends of detected materials are coated with silicone oil, to guarantee it and heat supply end, heat absorbing end good heat conduction are arranged.Have liquid inlet 9 and liquid outlet 10 in the upper end of heat absorbing end shell 14,9 draw thermocouple lead 3 from entering the mouth, draw thermocouple lead 4, is fixed with spreader plate 20 in upper and lower staggered mode in the heat absorbing end from exporting 10, can make liquid fully absorb heat, flow out with stable temperature.Be stained with heat-insulating block 15 in the outside of heat absorbing end, heat-insulating block 15 is connected with screw mandrel sleeve 16 with screw mandrel 17, and screw mandrel sleeve 16 is fixed on the casing, and handwheel 18 is equipped with in screw mandrel 17 outer ends, can regulate the position of heat absorbing end by handwheel 18, so that the material of chucking different size.
The utility model is simple in structure, convenient and practical, can accurately measure the thermal conductivity of material under normal temperature and the high temperature, measuring error is less than 5%, not only can be used for the test in fields such as industry, agricultural, building materials, scientific research, also can be the student of institution of higher learning and offer thermodynamics experiment course usefulness.
