Description
Technical field
The utility model relates to the check and analysis system of a class heat conduction efficiency of plate, this class sheet material by multiple material the long-pending compound complex biological material that constitutes of compound or various material layers make.
Background technology
At present, both at home and abroad scientist has worked out at coefficient of heat conductivity theory and actual detection methods such as medium coefficient of heat conductivity material such as plastics, epoxy resin, glass.These detection methods detection principle roughly is by the heater attached to test specimen upper surface (or lower surface) with a steady current, make heater discharge constant heat (or making heater become constant thermal source), simultaneously lay a temperature acquisition sensor, receive the real time temperature of test specimen at test specimen upper surface (or lower surface) apart from this heater certain distance.Calculate the value of coefficient of heat conductivity λ then with following formula:
Wherein: Q is the heat flow rate on the vertical direction between two parallel planes of measured material inside;
S is a conductive surface area;
(t1-t2) be the temperature difference with two sections;
δ is the distance of two sections.
Function ratio in the formula is the λ value under temperature (t1-t2)/2.
This detection method is effective to the thermal Conductivity Determination of above-mentioned medium coefficient of heat conductivity material, yet this method is used on the long-pending compound biological material that constitutes complexity of by multiple material compound or various material layers, and that testing result always obtains is inaccurate, can not compellent answer.Simple example is that this method can't realize accurate detection in the heat conducting law actual measurement on the floor made from this kind material, and the most tangible performance is that experiment does not have repeatability.
This is the complicacy that himself is structurally arranged because of or the long-pending compound complex biological material that constitutes of various material layers compound by multiple material.With the made heat conduction floor of this material is example, under the situation in short supply of biomass resource in the world today, for efficiently utilizing resource, floor manufacturer makes three layers even more multi-layered with the heat conduction floor, wherein, the surface rare tree on floor, middle or following with cheap artificial forest seeds.Perhaps the lower surface mount layer of metal film at consolidated floor makes it improve heat transfer efficiency, this structure is different from materials such as plastics, epoxy resin, glass fully, if remove to measure its coefficient of heat conductivity with existing coefficient of heat conductivity method, this just makes the value of above-mentioned λ become complicated and uncertain more, because also nobody proves after different materials is compound at present, the value of λ can add up, and its measurement result does not just have accuracy to say.That is to say existing thermal conductivity measurement method can not hold exactly this by multiple material the heat conducting law of the long-pending compound complex biological material that constitutes of compound or various material layers.Secondly, when detecting in this way, test specimen is exposed to extraneous, and portion of energy will be discharged into the environment at place from the marginal portion of test specimen during test, thereby make the result of detection inaccurate, cause the result of twice detection to differ greatly.
In sum, finding out method of testing and system thereof at long-pending compound complex biological material heat conductivility that constitutes of or various material layers compound by multiple material and rule thereof, is that all seem very necessary today for timber scientific research and building, ornament materials develop rapidly.
