以下、本発明を図面により詳細に説明する。図1は、本発明を適用した熱線トランスの一実施形態を示す斜視図である。   Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a heat ray transformer to which the present invention is applied.

機器1の発熱部は、冷却水W1により冷却され、排熱水W2が出力される。排熱水W2の温度は、常温プラスαの低温である。この排熱水W2は、1次流体として所定容量の発熱体2に入力され、これを加熱した後に排熱水W3として排出される。発熱体2は、所定面積の放熱板21を有し、1次流体W2で加熱された放熱板21の面に直交して平行な熱線Hが放射される。   The heat generating part of the device 1 is cooled by the cooling water W1, and the exhaust heat water W2 is output. The temperature of the exhaust hot water W2 is a normal temperature plus a low temperature α. The exhaust heat water W2 is input as a primary fluid to the heating element 2 having a predetermined capacity, and is heated and discharged as exhaust heat water W3. The heating element 2 has a heat radiating plate 21 having a predetermined area, and radiates heat rays H that are orthogonal to and parallel to the surface of the heat radiating plate 21 heated by the primary fluid W2.

この放熱板21に対向して、前記平行な熱線Hを反射し、その焦点位置に集光させる複数(図では4個)の主反射板31,32,33,34が配置されている。これら主反射板31,32,33,34の焦点位置には、2次流体W4が流れるパイプ部材41,42,43,44が配置されており、主反射板から反射されて集光された熱線Hにより加熱される。   A plurality of (four in the figure) main reflectors 31, 32, 33, and 34 are arranged opposite to the heat radiating plate 21 to reflect the parallel heat rays H and collect them at the focal position. Pipe members 41, 42, 43, and 44 through which the secondary fluid W4 flows are arranged at the focal positions of the main reflectors 31, 32, 33, and 34, and the heat rays reflected from the main reflector and collected. Heated by H.

更に、放熱板21とパイプ部材41,42,43,44との間に、これらパイプ部材と対向して、パイプ部材41,42,43,44からの熱線を反射してその焦点位置にあるパイプ部材に集光させる副反射板51,52,53,54が設けられている。   Further, between the heat radiating plate 21 and the pipe members 41, 42, 43, 44, the pipes located at the focal position by reflecting the heat rays from the pipe members 41, 42, 43, 44 facing the pipe members Sub-reflecting plates 51, 52, 53, and 54 for condensing light on the member are provided.

パイプ部材41,42,43,44は、1本のパイプを折り曲げて構成され、その一端側より発熱体2の排熱水W3の一部を2次流体W4として分流供給し、他端より高温に変換された出力流体W5を排出する。   The pipe members 41, 42, 43, and 44 are formed by bending one pipe, and a part of the exhaust heat water W3 of the heating element 2 is supplied as a secondary fluid W4 from one end side of the pipe member 41, and is heated at a higher temperature than the other end. The output fluid W5 converted into is discharged.

図2は、本発明を適用した熱線トランスの要部を示す横断面図である。発熱体2の熱を放射する放熱板21からの平行な熱線Hを反射する主反射板31,32,33,34は、AL等の素材または表面を鏡面コートした半円筒乃至は半円筒型に近い形状をし、放熱板21からの平行な熱線Hが結ぶ焦点位置にパイプ部材41,42,43,44が配置されている。   FIG. 2 is a cross-sectional view showing a main part of a heat ray transformer to which the present invention is applied. The main reflectors 31, 32, 33, and 34 that reflect parallel heat rays H from the radiator 21 that radiates the heat of the heating element 2 are made of a material such as AL or a semi-cylindrical or semi-cylindrical type whose surface is mirror-coated The pipe members 41, 42, 43, and 44 are arranged at a focal position that has a close shape and is connected by the parallel heat rays H from the heat radiation plate 21.

放熱板21は、黒体に近づけるために黒く塗装されて熱線Hの放射効率を高めている。黒体に近づけた放熱板21から放射された平行熱線(電磁波)Hは、円筒型の主反射板31,32,33,34で反射される。   The heat radiating plate 21 is painted black so as to be close to a black body to enhance the radiation efficiency of the heat ray H. Parallel heat rays (electromagnetic waves) H radiated from the heat sink 21 close to the black body are reflected by the cylindrical main reflectors 31, 32, 33, and 34.

円筒型の反射面を備える主反射板31,32,33,34の焦点位置に配置された、2次流体W4が流れるパイプ部材41,42,43,44も黒く塗られ、熱線の吸収効率を高めている。   Pipe members 41, 42, 43, and 44 through which the secondary fluid W4, which is disposed at the focal position of the main reflectors 31, 32, 33, and 34 having a cylindrical reflection surface, are also painted black, thereby improving the efficiency of heat ray absorption. It is increasing.

更に、主反射板及びパイプ部材からの熱線を反射してその焦点位置にあるパイプ部材に集光させる副反射板51,52,53,54の、放熱板21に対向する背面側も、放熱板21からの熱線Hの一部を受けるので、黒く塗られて熱線の吸収効率を高めている。   Further, the back side of the sub-reflecting plates 51, 52, 53, and 54, which reflects the heat rays from the main reflecting plate and the pipe member and collects the condensed light on the pipe member at the focal position, also faces the heat radiating plate 21. Since a part of the heat ray H from 21 is received, it is painted black to increase the absorption efficiency of the heat ray.

放熱板21から放射される熱線Hは、5〜20μmの赤外線領域にあり、放熱板21から効率よく放射され、主反射板で反射し、パイプ部材位置に焦点を結び、効率よく熱を吸収する構造になっている。   The heat ray H radiated from the heat radiating plate 21 is in the infrared region of 5 to 20 μm, is radiated from the heat radiating plate 21 efficiently, is reflected by the main reflector, focuses on the pipe member position, and efficiently absorbs heat. It has a structure.

そのパイプ部材を循環する2次流体W4は、常温に近い温度帯であるために、温度変換比を上げるためには、主反射板の表面積Aを極力大きくする。一方、パイプ部材の表面積Bは、中を流れる2次流体W4の流量を考慮した上で極力小さくする。   Since the secondary fluid W4 circulating through the pipe member is in a temperature zone close to room temperature, the surface area A of the main reflector is increased as much as possible in order to increase the temperature conversion ratio. On the other hand, the surface area B of the pipe member is made as small as possible in consideration of the flow rate of the secondary fluid W4 flowing therethrough.

ここで、黒体理論によると、面積比A/Bに相当する熱がパイプ部材側に移動する。これは、電気的なトランスに相当し、変圧可能な電圧に相当するものが温度である。また、トランスの巻線比に相当するものが面積比(正確には面積の4乗根比)である。その意味で、本発明の構成は、熱線トランスと称することができる。   Here, according to the black body theory, heat corresponding to the area ratio A / B moves to the pipe member side. This corresponds to an electrical transformer, and the temperature corresponds to a voltage that can be transformed. The area ratio (more precisely, the fourth root ratio of the area) corresponds to the winding ratio of the transformer. In that sense, the configuration of the present invention can be referred to as a heat ray transformer.

パイプ部材を流れる2次流体W4は、吸収した熱により加熱され、理想的には主反射板の温度よりもパイプ部材の温度は上昇する。ここで、熱損失を考慮して面積比A/Bを十分にとることが重要である。また、本発明の構成を真空中に配置することにより、熱変換効率を更に向上させることができる。   The secondary fluid W4 flowing through the pipe member is heated by the absorbed heat, and ideally the temperature of the pipe member rises higher than the temperature of the main reflector. Here, it is important to take a sufficient area ratio A / B in consideration of heat loss. Moreover, the heat conversion efficiency can be further improved by arranging the configuration of the present invention in a vacuum.

実施形態では、1次流体及び2次流体は通常の冷却システムで使用される水を例示したが、他の流体であってもよい。実施形態では、発熱体2の排熱水W3の一部を2次流体W4として分流供給しているが、2次流体W4を独立した循環系とすることもできる。   In the embodiment, the primary fluid and the secondary fluid are exemplified as water used in a normal cooling system, but other fluids may be used. In the embodiment, a part of the exhaust heat water W3 of the heating element 2 is supplied as a secondary fluid W4, but the secondary fluid W4 may be an independent circulation system.
