Description

本発明は、断熱材が所定の断熱性能を有しているか否かを検査する検査方法と、それを実行する検査装置に関するものである。   The present invention relates to an inspection method for inspecting whether or not a heat insulating material has a predetermined heat insulating performance, and an inspection apparatus for executing the inspection method.

従来の検査装置は、被測定物の両面を温度制御して温度差をつけ、熱流束と温度差、厚みを測定することにより熱伝導率を求めている。   A conventional inspection apparatus obtains a thermal conductivity by controlling the temperature of both surfaces of an object to be measured to create a temperature difference, and measuring a heat flux, a temperature difference, and a thickness.

また、被測定物と熱抵抗材の間で熱を発生させて、被測定物内部と熱抵抗材内部に熱を流し、熱抵抗材の少なくとも２箇所の温度差から被測定物の熱伝導率を求める装置もある（例えば、特許文献１参照）。   In addition, heat is generated between the object to be measured and the heat resistance material to flow heat inside the object to be measured and the heat resistance material, and the thermal conductivity of the object to be measured is determined from the temperature difference between at least two locations of the heat resistance material. There is also a device for obtaining (see, for example, Patent Document 1).

図４は、特許文献１に記載された従来の熱伝導率測定方法の概略断面図である。図４に示すように被測定物１と、熱抵抗材２と、熱発生装置３から構成されている。   FIG. 4 is a schematic cross-sectional view of a conventional thermal conductivity measurement method described in Patent Document 1. As shown in FIG. 4, the device includes a device under test 1, a heat resistance material 2, and a heat generator 3.

以上のように構成された検査装置について、以下その動作を説明する。   The operation of the inspection apparatus configured as described above will be described below.

まず、被測定物１と熱抵抗材２の内部に熱発生装置３より熱を流し、熱抵抗材２の少なくとも２箇所の温度差から被測定物１の熱伝導率を求める。
特開２００２−１３１２５７号公報 First, heat is supplied from the heat generating device 3 to the device under test 1 and the heat resistance material 2, and the thermal conductivity of the device under test 1 is obtained from the temperature difference between at least two locations of the heat resistance material 2.
JP 2002-131257 A

しかしながら、上記従来の構成では、熱流束センサーの精度の面から低熱伝導率の被測定物は、熱流束センサーが小さいと測定できない問題があり、熱流束センサーの精度から測定できる熱伝導率と被測定物の大きさに制限があった。   However, in the conventional configuration described above, there is a problem that an object to be measured with low thermal conductivity cannot be measured if the heat flux sensor is small in terms of accuracy of the heat flux sensor. There was a limit to the size of the object to be measured.

また、特許文献１の構成では、被測定物の片面上の少なくとも２箇所温度測定しなければならず、測定精度を上げるためには一定の距離間以上で数箇所の温度測定が必要であった。そのため、被測定物が小さいと測定精度が落ちてしまう問題があった。また、２箇所の温度差から熱伝導率を出すため、被測定物での２箇所間の温度差と熱伝導率の関係を実測してだす必要がある。そのため、測定の工数が増えてしまう問題があった。   Further, in the configuration of Patent Document 1, it is necessary to measure the temperature of at least two places on one side of the object to be measured. In order to increase the measurement accuracy, it is necessary to measure several temperatures over a certain distance. . For this reason, there is a problem that the measurement accuracy is lowered when the object to be measured is small. Further, in order to obtain the thermal conductivity from the temperature difference between the two locations, it is necessary to actually measure the relationship between the temperature difference between the two locations on the object to be measured and the thermal conductivity. For this reason, there is a problem that the number of measurement steps increases.

本発明は、上記従来の課題を解決するもので、特に５０Ｗ／ｍ2Ｋ以下の熱貫流率の断熱材の断熱性能を簡単に判定することができる検査方法と検査装置を提供するものである。 This invention solves the said conventional subject, and provides the test | inspection method and test | inspection apparatus which can determine easily the heat insulation performance of the heat insulating material of the heat transmissivity of 50 W / m < 2 > K or less especially. .

上記従来の課題を解決するために、本発明の検査装置は、断熱材の裏表面に温度差を付けて温度差を測定するようにしたものである。   In order to solve the above-described conventional problems, the inspection apparatus of the present invention measures the temperature difference by attaching a temperature difference to the back surface of the heat insulating material.

これによって、前もって温度差と熱貫流率の関係を実測することなく、（数１）より温度差と熱貫流導率の相関関係が導けるので、熱還流率が所定値以下であることを温度差より判定することができ、様々な熱伝導率、形状、大きさの断熱材の断熱性能を簡単に判定することができる。   As a result, the correlation between the temperature difference and the heat flow conductivity can be derived from (Equation 1) without actually measuring the relationship between the temperature difference and the heat flow rate beforehand. It is possible to more easily determine, and it is possible to easily determine the heat insulation performance of the heat insulating materials having various thermal conductivities, shapes, and sizes.

In addition, since the correlation between the heat transmissibility and the temperature difference between the front and back surfaces of the heat insulating material is uniquely determined if the ambient temperature and the heat transfer coefficient in the inspection conditions are the same, there is no need to obtain correlation data in advance. Can be shortened.

This is an inspection device that measures the ambient temperature, knows the temperature at the time of measurement, and corrects the correlation data between the thermal conductivity and the temperature difference between the two surfaces.

以下、本発明の実施の形態について、図面を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（実施の形態１）
図１は、本発明の実施の形態１における検査装置の測定部概略図である。図２は、本発明の実施の形態１における熱貫流率と断熱材両面の温度差との相関関係図である。図３は、本発明の実施の形態１における熱伝導率と断熱材両面の温度差との相関関係図である。 (Embodiment 1)
FIG. 1 is a schematic diagram of a measurement unit of the inspection apparatus according to Embodiment 1 of the present invention. FIG. 2 is a correlation diagram between the heat transmissivity and the temperature difference between both surfaces of the heat insulating material in Embodiment 1 of the present invention. FIG. 3 is a correlation diagram between the thermal conductivity and the temperature difference between both surfaces of the heat insulating material in Embodiment 1 of the present invention.

図１、図２、図３において、検査装置の測定部８は、風による影響を防ぐケース７と、断熱材６の片面に接触し温度制御する熱源４と、断熱材６の他面から挟みこむ放熱器９を備え、断熱材６の熱源接触面とその面に対向する面との温度を測定する温度センサー６から構成される。また、周囲温度、熱伝達率を予め入力しておくことにより（数１）より算出される温度差と熱貫流率の相関関係データ、もしくは温度差と熱貫流率の相関関係のデータを備える。   1, 2, and 3, the measurement unit 8 of the inspection apparatus is sandwiched from the case 7 that prevents the influence of wind, the heat source 4 that is in contact with one surface of the heat insulating material 6 to control the temperature, and the other surface of the heat insulating material 6. It comprises a temperature sensor 6 that includes a heat sink 9 and measures the temperature of the heat source contact surface of the heat insulating material 6 and the surface facing the surface. In addition, correlation data between the temperature difference and the heat transmissivity calculated from (Equation 1) by inputting the ambient temperature and the heat transfer coefficient in advance, or data on the correlation between the temperature difference and the heat transmissivity is provided.

また、好ましくは断熱材５の厚みを温度測定と同時に測定するセンサーを備え、その厚みより熱貫流率を熱伝導率に変換する機能を有する。また、周囲温度を測定するセンサーを備える。また、温度センサー６は、好ましくはひとつの断熱材５の片面に少なくとも２点以上備える。また、好ましくは断熱材の熱貫流率が５０Ｗ／ｍ2Ｋ以下である。また、好ましくは断熱材の厚みが５ｍｍ以下である
以上のように構成された検査装置について、以下その作用を説明する。 In addition, a sensor for measuring the thickness of the heat insulating material 5 at the same time as the temperature measurement is preferably provided, and the function of converting the heat transmissivity into the thermal conductivity is obtained based on the thickness. In addition, a sensor for measuring the ambient temperature is provided. Further, the temperature sensor 6 is preferably provided with at least two points on one side of one heat insulating material 5. Further, the thermal conductivity of the heat insulating material is preferably 50 W / m 2 K or less. Moreover, the thickness of the heat insulating material is preferably 5 mm or less. The operation of the inspection apparatus configured as described above will be described below.

断熱材５の片面を熱源４により温度制御し、温度センサー６により断熱材５の表面と裏面の温度を測定し、温度差を出す。その測定温度差と図２の相関関係より、熱還流率が所定値以下であることを温度差より判定することができる。   The temperature of one surface of the heat insulating material 5 is controlled by the heat source 4, the temperature of the front surface and the back surface of the heat insulating material 5 is measured by the temperature sensor 6, and a temperature difference is obtained. Based on the correlation between the measured temperature difference and FIG. 2, it can be determined from the temperature difference that the heat reflux rate is equal to or less than a predetermined value.

以上のように、本実施の形態においては、所定温度の熱源４と接した断熱材５の熱源接触面とその面に対向する面との温度差と、検査条件の周囲温度と熱伝達率とより算出される断熱材５の熱貫流率と断熱材表面と裏面との温度差の相関関係から断熱材の断熱性能を判定するので、熱還流率が所定値以下であることを温度差より判定することができ、断熱材５の断熱性能を検査することができる。   As described above, in the present embodiment, the temperature difference between the heat source contact surface of the heat insulating material 5 in contact with the heat source 4 at a predetermined temperature and the surface facing the surface, the ambient temperature and the heat transfer coefficient of the inspection conditions Since the heat insulation performance of the heat insulating material is determined from the correlation between the heat transmissivity of the heat insulating material 5 calculated and the temperature difference between the heat insulating material surface and the back surface, it is determined from the temperature difference that the heat reflux rate is a predetermined value or less. The heat insulating performance of the heat insulating material 5 can be inspected.

また、温度を測定するだけなので短時間で検査を行うことができる。また、熱貫流率と断熱材表面と裏面との温度差の相関関係が検査条件の周囲温度と熱伝達率が同じならば一意的に決まるので、前もって相関関係データを取る必要がないので時間が短縮できる。   Moreover, since only temperature is measured, it can test | inspect in a short time. In addition, since the correlation between the heat transmissibility and the temperature difference between the front and back surfaces of the heat insulating material is uniquely determined if the ambient temperature and the heat transfer coefficient in the inspection conditions are the same, there is no need to obtain correlation data in advance. Can be shortened.

また、断熱材の熱貫流率が５０Ｗ／ｍ2Ｋ以下なら、図２よりわかるように熱貫流率に対する断熱材表面と裏面との温度差の傾きが大きいので、検査精度が向上する。また、断熱材５の厚みが５ｍｍ以下なら、図２に厚みのファクターを入れた図３や（表１）からみると、熱伝導率に対する断熱材表面と裏面との温度差の傾きが大きいので、検査精度が向上し、また薄いことにより検査時間が短縮できる。 Also, if the thermal conductivity of the heat insulating material is 50 W / m 2 K or less, as can be seen from FIG. 2, the inclination of the temperature difference between the heat insulating material surface and the back surface with respect to the thermal flow rate is large, so the inspection accuracy is improved. Also, if the thickness of the heat insulating material 5 is 5 mm or less, the temperature difference between the heat insulating material surface and the back surface with respect to the thermal conductivity is large as seen from FIG. 3 (Table 1) with the thickness factor added to FIG. Inspection accuracy is improved, and inspection time can be shortened by being thin.

また、風による影響を減らすケース７を備えており、熱伝達率が一定になることで（数１）より算出できる熱貫流率と断熱材表面と裏面との温度差の相関関係と実測温度差との差を少なくできるので、検査精度を向上できる。
Figure 2006071565
 Moreover, the case 7 for reducing the influence of wind is provided, and the correlation between the heat transmissibility that can be calculated from (Equation 1) and the temperature difference between the front and back surfaces of the heat insulating material and the actually measured temperature difference when the heat transfer coefficient becomes constant. Inspection accuracy can be improved.

また、厚みの測定ができることにより、断熱材５個々の正確な厚みがわかり、製品規格外の厚みの断熱材を抽出することができ、検査効率が向上する。また、周囲温度を測定できることにより、（数１）より算出できる熱貫流率と断熱材表面と裏面との温度差の相関関係と実測温度差との差を少なくでき、検査精度を向上できる。   Further, since the thickness can be measured, the accurate thickness of each heat insulating material 5 can be known, and a heat insulating material having a thickness outside the product standard can be extracted, thereby improving inspection efficiency. Further, since the ambient temperature can be measured, the difference between the measured thermal difference and the correlation between the heat transmissibility calculated from (Equation 1) and the temperature difference between the front and back surfaces of the heat insulating material can be reduced, and the inspection accuracy can be improved.

また、測定点一箇所につき複数の温度センサー１１をもちいることにより、断熱材５の表面の段差や、断熱材５の密度差などのバラツキによる測定温度バラツキを低減でき、検査精度を向上することができる。なお、本実施の形態では断熱材５の片面に放熱器９を接触させているが、それを空気に換えることも可能である。空気に換えることにより、測定温度の安定するまでの時間が短くなり、検査効率が向上する。また、相関関係において熱貫流率を用いているが、これは熱を示すひとつの指標であり、これが熱伝導率、熱流速等であっても同様のことが行える。   In addition, by using a plurality of temperature sensors 11 for each measurement point, it is possible to reduce the measurement temperature variation due to variations in the surface step of the heat insulating material 5 and the density difference of the heat insulating material 5, and to improve inspection accuracy. Can do. In addition, in this Embodiment, although the heat radiator 9 is made to contact the single side | surface of the heat insulating material 5, it can also be changed to air. By changing to air, the time until the measurement temperature is stabilized is shortened, and the inspection efficiency is improved. Moreover, although the heat transmissivity is used in the correlation, this is one index indicating heat, and the same can be done even if this is heat conductivity, heat flow rate, or the like.

以上のように、本発明にかかる検査装置は、断熱材の両面に温度差を付け、両面の温度を測定することで熱伝導率が所定範囲にあることがわかり、断熱材の断熱性能を短時間で簡単に検査することが可能となるので、真空断熱材の生産ラインでの検査に適用できる。   As described above, the inspection apparatus according to the present invention shows that the thermal conductivity is within a predetermined range by making a temperature difference on both surfaces of the heat insulating material and measuring the temperature on both surfaces, thereby reducing the heat insulating performance of the heat insulating material. Since it is possible to easily inspect in time, it can be applied to inspection on the production line of vacuum heat insulating material.
