(57) [Abstract] [Purpose] To improve the responsiveness of heat flux measurement of a heat flux detector. [Structure] Since one end of the heat receiving part side lead wire 5 is connected to the heat receiving part 15 fixed to the reference temperature part 1 via the temperature difference generating part 14 by ultrasonic welding 16, the heat receiving part 15 is It can be formed into a foil shape, and the heat receiving portion 1 can be formed.

Description
【０００１】[0001]
本考案は熱流束検出器に関するものである。 The present invention relates to a heat flux detector.
【０００２】[0002]
図２は従来より用いられている熱流束検出器の一例を示し、該熱流束検出器の 構成を説明すると、銅を円柱状に形成した基準温度部１の一端面に、銅よりも熱 伝導性が低いコンスタンタン（銅、ニッケル合金）を円盤状に形成した温度差発 生部２の一面をろう付けあるいは拡散接合により固着し、該温度差発生部２の他 面に、銅をフランジ部１０を有する円盤状に形成した受熱部３の反フランジ部１ ０側の面をろう付けあるいは拡散接合により固着している。 FIG. 2 shows an example of a heat flux detector that has been conventionally used. To explain the structure of the heat flux detector, one end surface of the reference temperature part 1 formed of copper in a cylindrical shape is more thermally conductive than copper. One surface of the temperature difference generating part 2 formed of disk-shaped constantan (copper, nickel alloy) having low heat resistance is fixed by brazing or diffusion bonding, and copper is flanged on the other surface of the temperature difference generating part 2. The surface on the side opposite to the flange portion 10 of the heat receiving portion 3 formed in the shape of a disc having the above is fixed by brazing or diffusion bonding.
【０００３】 前記受熱部３のフランジ部１０に設けたリード線取り付け穴４には、銅製の受 熱部側リード線５の一端が挿入され、該受熱部側リード線５の一端は受熱部３に 対してろう付け６により接続されている。One end of a copper-made heat receiving portion side lead wire 5 is inserted into a lead wire mounting hole 4 provided in the flange portion 10 of the heat receiving portion 3, and one end of the heat receiving portion side lead wire 5 has a heat receiving portion 3 Are connected by brazing 6.
【０００４】 更に、受熱部側リード線５の他端と基準温度部側リード線７の他端は、前記受 熱部３と基準温度部１との間に温度差が発生したときに生じる起電力を測定する ための起電力測定部８に接続されている。Further, the other end of the heat receiving part side lead wire 5 and the other end of the reference temperature part side lead wire 7 occur when a temperature difference occurs between the heat receiving part 3 and the reference temperature part 1. It is connected to an electromotive force measuring unit 8 for measuring electric power.
【０００５】 なお、図中９は基準温度部１内に設けられた冷却媒体流路であり、該冷却媒体 流路９に冷却媒体１２を流通させることにより、受熱部３に入射した熱量を除去 するようになっている。Reference numeral 9 in the figure denotes a cooling medium passage provided in the reference temperature portion 1. By circulating the cooling medium 12 through the cooling medium passage 9, the amount of heat incident on the heat receiving portion 3 is removed. It is supposed to do.
【０００６】 図２に示す熱流束検出器では、受熱部３のフランジ部１０側の面に、レーザー 光線等の熱線１３が入射することにより、受熱部３の温度が上昇して受熱部３と 基準温度部１の間に温度差が発生すると、受熱部３と基準温度部１との間に前記 温度差に比例した起電力が生じ、該起電力は受熱部側リード線５、基準温度部側 リード線７を介し起電力測定部８によって測定されるようになっている。In the heat flux detector shown in FIG. 2, when the heat ray 13 such as a laser beam is incident on the surface of the heat receiving portion 3 on the flange portion 10 side, the temperature of the heat receiving portion 3 rises and the heat receiving portion 3 and When a temperature difference occurs between the reference temperature part 1, an electromotive force proportional to the temperature difference is generated between the heat receiving part 3 and the reference temperature part 1. The electromotive force is the heat receiving part side lead wire 5, the reference temperature part. It is adapted to be measured by the electromotive force measuring unit 8 via the side lead wire 7.
【０００７】[0007]
ところが、上述した熱流束検出器では、受熱部３に受熱部側リード線５をろう 付け６によって固着する際に、受熱部３及び温度差発生部２が熱によって変形し たり、あるいは溶融しないようにするために、受熱部３及び温度差発生部２の厚 さを５ｍｍ程度にしているので、受熱部３及び温度差発生部２の熱容量が比較的 大きい。 However, in the heat flux detector described above, when the heat receiving part-side lead wire 5 is fixed to the heat receiving part 3 by brazing 6, the heat receiving part 3 and the temperature difference generating part 2 are not deformed or melted by heat. For this reason, the thickness of the heat receiving portion 3 and the temperature difference generating portion 2 is set to about 5 mm, so that the heat capacity of the heat receiving portion 3 and the temperature difference generating portion 2 is relatively large.
【０００８】 そこで、図３に示すように、横軸に時刻Ｔ（図３において横軸一目盛は０．１ 秒を表わしている）を、縦軸に熱流束検出器が出力する起電力Ｗをとり、熱線１ ３が受熱部３に入射してから熱流束検出器が出力する起電力Ｗが受熱部３に入射 している熱線１３の熱エネルギーに相当する値になるまでに要する時間を調べて みると、図２に示す熱流束検出器では、前述したように受熱部３及び温度差発生 部２の熱容量が比較的大きく、受熱部３及び温度差発生部２が昇温されにくいの で、図３に破線で示すように時刻Ｔａより時刻Ｔｂの間に発射された熱線１３が 受熱部３に入射してから、熱流束検出器が出力する起電力Ｗが受熱部３に入射し ている熱線１３の熱エネルギーに相当する値になるのに約１．５秒以上掛かる。Therefore, as shown in FIG. 3, the horizontal axis represents time T (in FIG. 3, one scale on the horizontal axis represents 0.1 second), and the vertical axis represents the electromotive force W output by the heat flux detector. And the time required for the electromotive force W output from the heat flux detector to reach a value corresponding to the thermal energy of the heat ray 13 incident on the heat receiving section 3 after the heat ray 13 enters the heat receiving section 3. Upon examination, in the heat flux detector shown in FIG. 2, as described above, the heat capacities of the heat receiving part 3 and the temperature difference generating part 2 are relatively large, and it is difficult for the heat receiving part 3 and the temperature difference generating part 2 to rise in temperature. Then, as shown by the broken line in FIG. 3, after the heat ray 13 emitted from the time Ta to the time Tb enters the heat receiving section 3, the electromotive force W output from the heat flux detector enters the heat receiving section 3. It takes about 1.5 seconds or more to reach the value corresponding to the thermal energy of the heating wire 13.
【０００９】 また、受熱部３及び温度差発生部２の熱容量が大きいということは、受熱部３ 及び温度差発生部２が熱線１３により一旦昇温されると、熱を逃しにくい性質を 有していることになる。Further, the large heat capacities of the heat receiving part 3 and the temperature difference generating part 2 have a property that once the temperature of the heat receiving part 3 and the temperature difference generating part 2 is raised by the heating wire 13, it is difficult for heat to escape. It will be.
【００１０】 従って、図２に示す熱流束検出器では、短時間のうちに熱エネルギー量が変動 する熱線等に対して起電力の変化を機敏に追従させることができず、受熱部３に 入射する熱線の熱エネルギー量の変動に対しての起電力変化の追従性、すなわち 熱流束検出器の応答性が良いとはいえない。Therefore, in the heat flux detector shown in FIG. 2, the change in electromotive force cannot be swiftly followed with respect to the heat ray or the like in which the amount of heat energy fluctuates within a short time, and the heat flux is incident on the heat receiving unit 3. It cannot be said that the followability of changes in electromotive force with respect to changes in the amount of heat energy of the heating wire, that is, the response of the heat flux detector is good.
【００１１】 本考案は、上述した問題点を解決するもので、熱流束測定の応答性が良い熱流 束検出器を提供することを目的としている。The present invention solves the above-mentioned problems, and an object of the present invention is to provide a heat flux detector having good response in heat flux measurement.
【００１２】[0012]
本考案は、金属をブロック状に形成した基準温度部の一面に、該基準温度部を 形成する金属よりも熱伝導性が低い金属を箔状に形成した温度差発生部の一面を 固相接合またはろう接により固着し、該温度差発生部の他面に、前記基準温度部 を形成する金属と同一の金属を箔状に形成した受熱部を固相接合により固着し、 該受熱部に受熱部側リード線の一端を超音波溶接により接続し、前記基準温度部 に基準温度部側リード線の一端を接続し、前記受熱部側リード線の他端と基準温 度部側リード線の他端を起電力測定部に接続したものである。 The present invention provides solid-phase bonding of one surface of a temperature difference generating portion, which is a foil-shaped metal having a lower thermal conductivity than the metal forming the reference temperature portion, to one surface of the reference temperature portion where the metal is formed in a block shape. Alternatively, it is fixed by brazing, and the other surface of the temperature difference generating portion is fixed to the other surface of the reference temperature portion in the form of a foil with a heat-receiving portion fixed by solid-phase bonding, and the heat-receiving portion receives heat. One end of the lead wire on the part side is connected by ultrasonic welding, one end of the lead wire on the reference temperature part is connected to the reference temperature part, the other end of the lead wire on the heat receiving part side and the other lead wire on the reference temperature part side are connected. The end is connected to the electromotive force measurement unit.
【００１３】[0013]
本考案の熱流束検出器では、受熱部に受熱部側リード線の一端を超音波溶接に より接続しているので、受熱部を箔状に形成することができ、また、受熱部とと もに温度差発生部を箔状に形成しているので、受熱部及び温度差発生部の熱容量 が小さくなって、受熱部及び温度差発生部が昇温されやすく、速やかに温度が定 常状態となり且つ熱を逃しやすくなり、よって、短時間のうちに熱エネルギー量 が変動する熱線に対して起電力の変化を機敏に追従させることができ、受熱部に 入射する熱線の熱エネルギー量の変動に対しての起電力変化の追従性、すなわち 熱流束検出器の応答性が良くなる。 In the heat flux detector of the present invention, one end of the lead wire on the heat receiving portion side is connected to the heat receiving portion by ultrasonic welding, so that the heat receiving portion can be formed in a foil shape, and also with the heat receiving portion. Since the temperature difference generation part is formed in the shape of a foil, the heat capacity of the heat reception part and the temperature difference generation part becomes small, the temperature of the heat reception part and the temperature difference generation part is easily raised, and the temperature quickly becomes the normal state. In addition, the heat can be easily dissipated, so that the change in electromotive force can be swiftly followed by the change in the heat energy of which the amount of heat energy fluctuates within a short time. The followability of the change in electromotive force, that is, the response of the heat flux detector is improved.
【００１４】[0014]
以下本考案の実施例を図面を参照しつつ説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【００１５】 図１は本考案の熱流束検出器の一実施例を示すもので、図中、図２と同一の符 号を付した部分は同一物を表わしている。FIG. 1 shows an embodiment of the heat flux detector of the present invention. In the figure, the same parts as those in FIG. 2 are the same.
【００１６】 銅を円柱状に形成した基準温度部１の一面に、銅よりも熱伝導性が低いコンス タンタンを箔状に形成した温度差発生部１４の一面を拡散接合（固相接合）によ り固着し、該温度差発生部１４の他面に、銅を箔状に形成した受熱部１５を拡散 接合により固着する。One surface of the reference temperature portion 1 formed of copper in a cylindrical shape and one surface of the temperature difference generation portion 14 formed of foil-like constantan having a lower thermal conductivity than copper are subjected to diffusion bonding (solid phase bonding). Then, the heat receiving portion 15 made of copper foil is fixed to the other surface of the temperature difference generating portion 14 by diffusion bonding.
【００１７】 受熱部１５に受熱部側リード線５の一端を超音波溶接１６により、また、前記 基準温度部１に基準温度部側リード線７の一端を超音波による点溶接１１により 接続し、前記受熱部側リード線５の他端と基準温度部側リード線７の他端を起電 力測定部８に接続する。One end of the heat receiving part side lead wire 5 is connected to the heat receiving part 15 by ultrasonic welding 16, and one end of the reference temperature part side lead wire 7 is connected to the reference temperature part 1 by ultrasonic point welding 11. The other end of the heat receiving part side lead wire 5 and the other end of the reference temperature part side lead wire 7 are connected to the electromotive force measuring part 8.
【００１８】 このように、本実施例の熱流束検出器では、受熱部側リード線７の一端を超音 波溶接によって受熱部１５に接合しているので、受熱部側リード線７を受熱部１ ５に接合する際に、該受熱部１５が熱による変形や損傷を受けることがなく、よ って、受熱部１５を図２に示す受熱部３に比べて厚さが極めて薄い箔状にするこ とができる。As described above, in the heat flux detector of the present embodiment, since one end of the heat receiving portion side lead wire 7 is joined to the heat receiving portion 15 by ultrasonic welding, the heat receiving portion side lead wire 7 is connected to the heat receiving portion. The heat receiving portion 15 is not deformed or damaged by heat when it is joined to the heat receiving portion 15. Therefore, the heat receiving portion 15 is formed into a foil shape having an extremely thin thickness as compared with the heat receiving portion 3 shown in FIG. can do.
【００１９】 上述した構成を有する熱流束検出器において、受熱部１５の反温度差発生部側 の面に、レーザー光線等の熱線１３が入射することにより、受熱部１５の温度が 上昇して受熱部１５と基準温度部１の間に温度差が発生すると、受熱部１５と基 準温度部１との間に前記温度差に比例した起電力が生じ、該起電力は受熱部側リ ード線５、基準温度部側リード線７を介し起電力測定部８によって測定される。In the heat flux detector having the above-described configuration, when the heat ray 13 such as a laser beam is incident on the surface of the heat receiving portion 15 on the side opposite to the temperature difference generating portion, the temperature of the heat receiving portion 15 rises and the heat receiving portion 15 rises. When a temperature difference occurs between the heat receiving unit 15 and the reference temperature unit 1, an electromotive force proportional to the temperature difference is generated between the heat receiving unit 15 and the reference temperature unit 1, and the electromotive force is the heat receiving unit side lead wire. 5, measured by the electromotive force measuring unit 8 via the reference temperature unit side lead wire 7.
【００２０】 このとき、本実施例の熱流束検出器では、受熱部１５及び温度差発生部１４を 箔状に形成して受熱部１５、温度差発生部１４の熱容量を小さくしているので、 受熱部１５、温度差発生部１４が昇温されやすく、速やかに温度が定常状態とな り、且つ熱を逃がしやすい。At this time, in the heat flux detector of the present embodiment, the heat receiving portion 15 and the temperature difference generating portion 14 are formed in a foil shape to reduce the heat capacities of the heat receiving portion 15 and the temperature difference generating portion 14. The temperature of the heat receiving portion 15 and the temperature difference generating portion 14 is easily raised, the temperature quickly becomes a steady state, and the heat is easily released.
【００２１】 そこで、図３に示すように、横軸に時刻Ｔを、縦軸に熱流束検出器が出力する 起電力Ｗをとり、熱線１３が受熱部１５に入射してから熱流束検出器が出力する 起電力Ｗが受熱部１５に入射している熱線１３の熱エネルギーに相当する値にな るまでに要する時間を調べてみると、本実施例の熱流束検出器では、前述したよ うに受熱部１５及び温度差発生部１４の熱容量が小さく、受熱部１５及び温度差 発生部１４が昇温されやすく且つ熱を逃がしやすくなっているので、図３に実線 で示すように時刻Ｔａより時刻Ｔｂの間に発射された熱線１３が受熱部１５に入 射すると、熱線１３が受熱部１５に入射してから熱流束検出器が出力する起電力 Ｗが受熱部１５に入射している熱線１３の熱エネルギーに相当する値になるのに 約０．２５秒程度しか掛からない。Therefore, as shown in FIG. 3, the horizontal axis represents the time T and the vertical axis represents the electromotive force W output by the heat flux detector, and the heat flux 13 enters the heat receiving unit 15 before the heat flux detector. When the time required for the electromotive force W output by the device to reach a value corresponding to the thermal energy of the heat ray 13 incident on the heat receiving portion 15 is examined, the heat flux detector of the present embodiment has the above-mentioned value. As described above, since the heat capacities of the heat receiving portion 15 and the temperature difference generating portion 14 are small and the heat receiving portion 15 and the temperature difference generating portion 14 are easily heated and easily dissipate heat, as shown by the solid line in FIG. When the heat ray 13 emitted during the time Tb enters the heat receiving portion 15, the electromotive force W output from the heat flux detector after the heat ray 13 is incident on the heat receiving portion 15 is incident on the heat receiving portion 15. It takes about 13 to reach the value equivalent to the heat energy of 13. It only takes about 0.25 seconds.
【００２２】 また、時刻Ｔｂより後に熱線１３が受熱部１５に入射しなくなると、熱流束検 出器が出力する起電力は約０．３秒程度で、時刻Ｔａより前の熱線１３が受熱部 １５に入射していないときの起電力と略同等の値になる。When the heat ray 13 does not enter the heat receiving portion 15 after the time Tb, the electromotive force output from the heat flux detector is about 0.3 seconds, and the heat ray 13 before the time Ta is received by the heat receiving portion 15. The value is almost the same as the electromotive force when it is not incident on 15.
【００２３】 従って、本実施例の熱流束検出器では、受熱部１５及び温度差発生部１４の熱 容量を小さくすることにより、短時間のうちに熱エネルギー量が変動する熱線に 対して起電力の変化を機敏に追従させることができ、受熱部１５に入射する熱線 の熱エネルギー量の変動に対しての起電力変化の追従性、すなわち熱流束検出器 の熱エネルギー量の変動に対する応答性が良くなる。Therefore, in the heat flux detector of this embodiment, by reducing the heat capacities of the heat receiving portion 15 and the temperature difference generating portion 14, the electromotive force is applied to the heat ray whose heat energy amount fluctuates in a short time. Of the heat ray incident on the heat receiving portion 15, that is, the changeability of the electromotive force change with respect to the change of the heat energy of the heat ray, that is, the responsiveness to the change of the heat energy of the heat flux detector. Get better.
【００２４】 なお、本考案の熱流束検出器は、上述の実施例にのみ限定されるものではなく 、本考案の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論であ る。It should be noted that the heat flux detector of the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.
【００２５】[0025]
以上述べたように、本考案の熱流束検出器によれば、受熱部に受熱部側リード 線の一端を超音波溶接により接続しているので、受熱部を箔状に形成することが でき、また、受熱部とともに温度差発生部を箔状に形成しているので、受熱部及 び温度差発生部の熱容量が小さくなって、受熱部及び温度差発生部が昇温されや すく、速やかに温度が定常状態となり且つ熱が逃げやすくなるので、受熱部に入 射する熱線の熱エネルギー量の変動に対しての起電力変化の追従性、すなわち熱 流束検出器の応答性が良くなるという優れた効果を奏し得る。 As described above, according to the heat flux detector of the present invention, since one end of the lead wire on the heat receiving portion side is connected to the heat receiving portion by ultrasonic welding, the heat receiving portion can be formed in a foil shape. Also, since the temperature difference generating part is formed in the shape of a foil together with the heat receiving part, the heat capacity of the heat receiving part and the temperature difference generating part becomes small, and the heat receiving part and the temperature difference generating part are likely to be heated, so that Since the temperature is in a steady state and heat easily escapes, the ability to follow the change in electromotive force with respect to changes in the amount of heat energy of the heat rays entering the heat receiving section, that is, the response of the heat flux detector is improved. It can exert an excellent effect.
