Description

この発明は、光を集めて発電する集光発電装置に関する。   The present invention relates to a concentrating power generation apparatus that collects light and generates electric power.

太陽光のエネルギーを電力に変換する太陽光発電システムでは、光電変換素子が太陽光を受けて温度上昇し、その温度上昇の影響で光電変換効率が低下するという問題がある。   In a photovoltaic power generation system that converts sunlight energy into electric power, there is a problem that the photoelectric conversion element receives sunlight and rises in temperature, and the photoelectric conversion efficiency decreases due to the rise in temperature.

対策として、光電変換素子に気中放熱冷却機構を取付けた構成の集光型太陽光発電装置が知られている（例えば特許文献１）   As a countermeasure, a concentrating solar power generation apparatus having a configuration in which an air heat radiation cooling mechanism is attached to a photoelectric conversion element is known (for example, Patent Document 1).

特開２０１０−４０９４０号公報JP 2010-40940 A

上記の集光型太陽光発電装置は、太陽光を受けるパラボラ反射板の焦点位置に光電変換素子を配置し、その光電変換素子に気中放熱冷却機構を取付けている。この構成では、パラボラ反射板に向かう太陽光の光路上に光電変換素子と気中放熱冷却機構およびその支持部材が存在し、それが光を遮るため、光電変換素子への集光量が少なる。   In the above concentrating solar power generation device, a photoelectric conversion element is disposed at the focal position of a parabolic reflector that receives sunlight, and an air heat radiation cooling mechanism is attached to the photoelectric conversion element. In this configuration, the photoelectric conversion element, the air heat radiation cooling mechanism, and its supporting member exist on the optical path of sunlight toward the parabolic reflector, and the light is blocked, so that the amount of light collected on the photoelectric conversion element is small.

安定した発電を行うためには、光電変換素子への集光量をできるだけ多くすることが望まれる。ただし、集光量が増えると、光電変換素子の温度上昇が大きくなって光電変換効率が低下するため、その温度上昇を抑制する対策が必要となる。   In order to perform stable power generation, it is desirable to increase the amount of light collected on the photoelectric conversion element as much as possible. However, when the amount of light collection increases, the temperature rise of the photoelectric conversion element increases and the photoelectric conversion efficiency decreases, so a measure for suppressing the temperature rise is required.

この発明の目的は、光電変換素子への集光量を多くすることができるとともに、光電変換素子の温度上昇を確実に抑制できる集光発電装置を提供することである。   An object of the present invention is to provide a condensing power generation apparatus that can increase the amount of light condensing on a photoelectric conversion element and reliably suppress the temperature rise of the photoelectric conversion element.

この発明の集光発電装置は、光電変換素子と、この光電変換素子の受光面に光を集める光学レンズと、前記光電変換素子に設けられた自励振動ヒートパイプと、を備える。   A condensing power generation device of the present invention includes a photoelectric conversion element, an optical lens that collects light on a light receiving surface of the photoelectric conversion element, and a self-excited vibration heat pipe provided in the photoelectric conversion element.

この発明によれば、光電変換素子への集光量が多くなるとともに、それに伴う光電変換素子の温度上昇を確実に抑制できる集光発電装置を提供できる。   According to this invention, while the amount of condensing to a photoelectric conversion element increases, the condensing electric power generation apparatus which can suppress reliably the temperature rise of the photoelectric conversion element accompanying it can be provided.

［１］以下、第１の実施形態について説明する。
図１に示すように、架台１の上面にブラケット２を介して基板３の下縁部が回動自在に枢支され、その基板３の下面と架台１の上面との間に支持ロッド４の先端が係止される。そして、基板３の上面に多数の集光発電装置１０が縦横に配置される。ブラケット２における基板３の回動位置および基板３に対する支持ロッド４の係止位置を調節することにより、各集光発電装置１０を太陽に向く最適な状態に設定することができる。 [1] The first embodiment will be described below.
As shown in FIG. 1, the lower edge of the substrate 3 is pivotally supported on the upper surface of the gantry 1 via a bracket 2, and the support rod 4 is interposed between the lower surface of the substrate 3 and the upper surface of the gantry 1. The tip is locked. A large number of concentrating power generation devices 10 are arranged vertically and horizontally on the upper surface of the substrate 3. By adjusting the rotation position of the substrate 3 in the bracket 2 and the locking position of the support rod 4 with respect to the substrate 3, each condensing power generation device 10 can be set in an optimum state facing the sun.

各集光発電装置１０の構成を図２および図３に示す。
１１は光電変換素子で、光が到来する方向に受光面１１ａを向けて配置され、受光面１１ａで受けた光をその受光量に対応する大きさの電力に変換して出力する。この光電変換素子１１の受光面１１ａの上方に、その受光面１１ａに光を集める集光手段として、光学レンズ１２が設けられる。 The configuration of each condensing power generation apparatus 10 is shown in FIGS.
A photoelectric conversion element 11 is arranged with the light receiving surface 11a facing in the direction in which light arrives, and converts the light received by the light receiving surface 11a into electric power having a magnitude corresponding to the amount of received light and outputs the converted electric power. An optical lens 12 is provided above the light receiving surface 11a of the photoelectric conversion element 11 as a light collecting means for collecting light on the light receiving surface 11a.

１３は伝熱体で、熱伝導性が良好な部材たとえば銅やアルミニウムによって光電変換素子１１と略同じ径を有する円柱状に形成され、軸方向端部が光電変換素子１１の背面部に取付けられる。そして、伝熱体１３の周面に、熱輸送性能の高い自励振動ヒートパイプ１４が取付けられる。   Reference numeral 13 denotes a heat transfer member, which is formed of a member having good thermal conductivity, such as copper or aluminum, into a cylindrical shape having substantially the same diameter as the photoelectric conversion element 11, and an axial end is attached to the back surface of the photoelectric conversion element 11. . And the self-excited vibration heat pipe 14 with high heat transport performance is attached to the peripheral surface of the heat transfer body 13.

自励振動ヒートパイプ１４は、１本の細管およびその細管に封入された流体とで構成される。細管は、伝熱体１３の周面に接する位置とその周面から同伝熱体１３の径方向に離間する位置との間を往復する状態に巻回されつつ、その巻回が伝熱体１３の周方向に沿って螺旋状に繰り返される形状を有する。この細管の各巻回部分は、伝熱体１３の周面に接する部分が加熱部（受熱部ともいう）、伝熱体１３の周面から離間する部分が冷却部となる。細管内の流体はそれぞれ表面張力によって形成された液状体および蒸気泡からなり、これら液状体および蒸気泡が管軸方向に分布している。なお、エンドレスの細管を用いているが、両端がそれぞれ閉じた非エンドレスの細管を用いてもよい。   The self-excited vibration heat pipe 14 is composed of a single thin tube and a fluid sealed in the thin tube. The thin tube is wound so as to reciprocate between a position in contact with the peripheral surface of the heat transfer body 13 and a position spaced apart from the peripheral surface in the radial direction of the heat transfer body 13, and the winding is performed in the heat transfer body. It has a shape that repeats spirally along 13 circumferential directions. As for each winding part of this thin tube, the part which contact | connects the surrounding surface of the heat exchanger 13 becomes a heating part (it is also called heat receiving part), and the part spaced apart from the surrounding surface of the heat exchanger 13 becomes a cooling part. The fluid in the narrow tube is composed of a liquid material and vapor bubbles formed by surface tension, respectively, and these liquid material and vapor bubbles are distributed in the tube axis direction. Although endless capillaries are used, non-endless capillaries with closed ends may be used.

太陽光を受けて温度上昇する光電変換素子１１の熱は、伝熱体１３を介して自励振動ヒートパイプ１４の加熱部に伝わり、その加熱部から蒸発潜熱として流体に伝わり、その流体を伝わって冷却部に運ばれ、凝縮潜熱となって気中に放出される。この放熱に伴い、冷却部が冷え、その冷熱が流体を伝わって加熱部に運ばれる。   The heat of the photoelectric conversion element 11 that rises in temperature upon receiving sunlight is transferred to the heating part of the self-excited vibration heat pipe 14 via the heat transfer body 13, and is transferred to the fluid as the latent heat of evaporation from the heating part, and is transferred to the fluid. Then, it is transported to the cooling section, where it is discharged into the air as latent heat of condensation. Along with this heat radiation, the cooling unit cools, and the cold heat is transferred to the fluid and conveyed to the heating unit.

このとき、自励振動ヒートパイプ１４の流体には、加熱部での蒸発作用および冷却部での凝縮作用により、加熱部と冷却部との間を揺れ動く自励的な振動いわゆる自励振動が生じる。すなわち、加熱部で生じる蒸気泡は冷却部へと流れ、冷却部で生じる液状体は加熱部へと流れる。この場合、加熱部から冷却部に向かう蒸気泡の流れ方向はその加熱部から冷却部を見た一方向および他方向においてランダムであり、冷却部から加熱部に向かう液状体の流れ方向もその冷却部から加熱部を見た一方向および他方向においてランダムである。   At this time, in the fluid of the self-excited vibration heat pipe 14, self-excited vibration that swings between the heating unit and the cooling unit, so-called self-excited vibration, is generated by the evaporation operation in the heating unit and the condensing operation in the cooling unit. . That is, the vapor bubbles generated in the heating unit flow to the cooling unit, and the liquid material generated in the cooling unit flows to the heating unit. In this case, the flow direction of the steam bubbles from the heating unit to the cooling unit is random in one direction and the other direction when the cooling unit is viewed from the heating unit, and the flow direction of the liquid material from the cooling unit to the heating unit is also the cooling direction. It is random in one direction and the other direction when the heating part is seen from the part.

この流体の自励振動によって加熱部から冷却部への熱輸送が継続し、光電変換素子１１の熱が効率よく気中に放出される。   Due to the self-excited vibration of the fluid, heat transport from the heating part to the cooling part continues, and the heat of the photoelectric conversion element 11 is efficiently released into the air.

以上のように、光電変換素子１１の受光面１１ａを光が到来する方向に向け、その受光面１１ａの上方に集光用の光学レンズ１２を設けることにより、より多くの光を光電変換素子１１の受光面１１ａに集めることができる。これにより、光電変換素子１１の出力が増大する。   As described above, by directing the light receiving surface 11a of the photoelectric conversion element 11 in the direction in which light arrives and providing the condensing optical lens 12 above the light receiving surface 11a, more light is converted into the photoelectric conversion element 11. Can be collected on the light receiving surface 11a. Thereby, the output of the photoelectric conversion element 11 increases.

集光量が増えると、それに伴って光電変換素子１１の温度上昇が大きくなるが、光電変換素子１１に伝熱体１３を取付け、その伝熱体１３に熱輸送性能の高い自励振動ヒートパイプ１４を取付けているので、光電変換素子１１の熱を効率よく気中に放出できる。これにより、光電変換素子１１の温度上昇を確実に抑制でき、ひいては光電変換素子１１の光電変換効率の低下を回避することができ、常に安定した発電が可能となる。   As the amount of collected light increases, the temperature rise of the photoelectric conversion element 11 increases accordingly. The heat transfer body 13 is attached to the photoelectric conversion element 11 and the self-excited vibration heat pipe 14 having high heat transport performance is attached to the heat transfer body 13. Is attached, the heat of the photoelectric conversion element 11 can be efficiently released into the air. Thereby, the temperature rise of the photoelectric conversion element 11 can be surely suppressed, and as a result, a decrease in the photoelectric conversion efficiency of the photoelectric conversion element 11 can be avoided, and stable power generation is always possible.

とくに、自励振動ヒートパイプ１４は、伝熱体１３の周面に接する位置とその周面から同伝熱体１３の径方向に離間する位置との間を往復する状態に巻回されつつ、その巻回が伝熱体１３の周方向に沿って螺旋状に繰り返される形状を有し、多数の巻回部分が伝熱体１３の周面全体を覆うように接するとともに、それぞれの巻回部分の放熱部が互いに離れてその相互間に十分な放熱空間を確保する構成であるから、伝熱体１３からの受熱効率に優れるとともに放熱部から気中への放熱効率にも優れ、もともと持っている高い熱輸送性能を最大限に発揮することができる。これにより、光電変換素子１１の温度上昇に対する抑制効果がより高まる。   In particular, the self-excited vibration heat pipe 14 is wound in a state of reciprocating between a position in contact with the peripheral surface of the heat transfer body 13 and a position spaced from the peripheral surface in the radial direction of the heat transfer body 13, The winding has a shape that is spirally repeated along the circumferential direction of the heat transfer body 13, and a large number of winding portions are in contact with each other so as to cover the entire peripheral surface of the heat transfer body 13, and each winding portion Since the heat dissipating parts are separated from each other and a sufficient heat dissipating space is ensured between them, the heat receiving efficiency from the heat transfer body 13 is excellent and the heat dissipating efficiency from the heat dissipating part to the air is originally possessed. High heat transport performance can be maximized. Thereby, the suppression effect with respect to the temperature rise of the photoelectric conversion element 11 increases more.

［２］第２の実施形態について説明する。
図４に示すように、集光発電装置１０が太陽に向かって傾斜状態で配置されることに対処し、自励振動ヒートパイプ１４の各巻回部分のうち、加熱部が上方で冷却部が下方となる位置関係を持つ少なくとも１つの巻回部分に、逆止弁１５が設けられる。 [2] A second embodiment will be described.
As shown in FIG. 4, the concentrating power generation apparatus 10 is disposed in an inclined state toward the sun, and the heating part is the upper part and the cooling part is the lower part among the winding parts of the self-excited vibration heat pipe 14. The check valve 15 is provided in at least one winding portion having the positional relationship as follows.

加熱部が上方で冷却部が下方となる位置関係を持つ巻回部分では、冷却部で凝縮して加熱部の方向（昇り方向）に向かう液状体の流れに対し、重力が加わる。この重力による液状体の落下を抑えるために逆止弁１５を設けている。
他の構成、作用、効果は、第１の実施形態と同じである。よって、その説明は省略する。 In the winding part having a positional relationship in which the heating part is above and the cooling part is below, gravity is applied to the flow of the liquid material condensed in the cooling part and moving in the direction of the heating part (upward direction). A check valve 15 is provided to prevent the liquid from falling due to gravity.
Other configurations, operations, and effects are the same as those in the first embodiment. Therefore, the description is omitted.

［３］第３の実施形態について説明する。
図５および図６に示すように、伝熱体１３の周面に、熱輸送性能の高い自励振動ヒートパイプ１６が取付けられる。図５は要部を側方から見た図、図６は図５を上方から見た図である。 [3] A third embodiment will be described.
As shown in FIGS. 5 and 6, a self-excited vibration heat pipe 16 having high heat transport performance is attached to the peripheral surface of the heat transfer body 13. FIG. 5 is a view of the main part as viewed from the side, and FIG. 6 is a view of FIG. 5 as viewed from above.

自励振動ヒートパイプ１６の細管は、伝熱体１３の周面に接する位置とその周面から同伝熱体１３の径方向に離間する位置との間を往復する状態に巻回されつつ、その巻回が伝熱体１３の軸方向に沿って繰り返され、かつ伝熱体１３の周方向における各巻回の位置がその伝熱体の周方向に沿って所定角度ずつずれる形状を有する。この細管の各巻回部分は、伝熱体１３の周面の略半分を被うように接する部分が加熱部となり、伝熱体１３の周面から離間する部分が冷却部となる。細管内の流体はそれぞれ表面張力によって形成された液状体および蒸気泡からなり、その液状体および蒸気泡が管軸方向に分布している。なお、エンドレスの細管を用いているが、両端がそれぞれ閉じた非エンドレスの細管を用いてもよい。   The thin tube of the self-excited vibration heat pipe 16 is wound in a state of reciprocating between a position in contact with the circumferential surface of the heat transfer body 13 and a position spaced in the radial direction of the heat transfer body 13 from the circumferential surface. The winding is repeated along the axial direction of the heat transfer body 13, and the position of each winding in the circumferential direction of the heat transfer body 13 has a shape shifted by a predetermined angle along the circumferential direction of the heat transfer body 13. As for each winding part of this thin tube, the part which touches so that substantially half of the surrounding surface of the heat exchanger 13 may be covered becomes a heating part, and the part spaced apart from the surrounding surface of the heat exchanger 13 becomes a cooling part. The fluid in the narrow tube is composed of a liquid material and vapor bubbles formed by surface tension, respectively, and the liquid material and vapor bubbles are distributed in the tube axis direction. Although endless capillaries are used, non-endless capillaries with closed ends may be used.

他の構成は、第１の実施形態に示した図１および図２と同じである。   Other configurations are the same as those in FIGS. 1 and 2 shown in the first embodiment.

光電変換素子１１の受光面１１ａへの集光量が増えることで光電変換素子１１の温度上昇が大きくなるが、光電変換素子１１に伝熱体１３を取付け、その伝熱体１３に熱輸送性能の高い自励振動ヒートパイプ１６を取付けているので、光電変換素子１１の熱を効率よく気中に放出できる。これにより、光電変換素子１１の温度上昇を確実に抑制でき、ひいては光電変換素子１１の光電変換効率の低下を回避することができ、常に安定した発電が可能となる。   Although the temperature rise of the photoelectric conversion element 11 increases as the amount of light collected on the light receiving surface 11a of the photoelectric conversion element 11 increases, the heat transfer body 13 is attached to the photoelectric conversion element 11, and the heat transfer performance of the heat transfer body 13 is improved. Since the high self-excited vibration heat pipe 16 is attached, the heat of the photoelectric conversion element 11 can be efficiently released into the air. Thereby, the temperature rise of the photoelectric conversion element 11 can be surely suppressed, and as a result, a decrease in the photoelectric conversion efficiency of the photoelectric conversion element 11 can be avoided, and stable power generation is always possible.

とくに、自励振動ヒートパイプ１６は、伝熱体１３の周面に接する位置とその周面から同伝熱体１３の径方向に離間する位置との間を往復する状態に巻回されつつ、その巻回が伝熱体１３の周方向に沿って螺旋状に繰り返され、かつ伝熱体１３の周方向における各巻回の位置がその伝熱体の周方向に沿って所定角度ずつずれる形状を有し、多数の巻回部分が伝熱体１３の周面全体を覆うように接するとともに、それぞれの巻回部分の放熱部が上下および水平の両方向において互いに離れてその相互間に十分な放熱空間を確保する構成であるから、伝熱体１３からの受熱効率に優れるとともに放熱部から気中への放熱効率にも優れ、もともと持っている高い熱輸送性能を最大限に発揮することができる。これにより、光電変換素子１１の温度上昇に対する抑制効果がより高まる。   In particular, the self-excited vibration heat pipe 16 is wound in a state of reciprocating between a position in contact with the circumferential surface of the heat transfer body 13 and a position spaced in the radial direction of the heat transfer body 13 from the circumferential surface. The winding is repeated spirally along the circumferential direction of the heat transfer body 13, and the position of each winding in the circumferential direction of the heat transfer body 13 is shifted by a predetermined angle along the circumferential direction of the heat transfer body. And a large number of winding portions are in contact with each other so as to cover the entire peripheral surface of the heat transfer body 13, and the heat radiating portions of the respective winding portions are separated from each other in both the vertical and horizontal directions, and a sufficient heat radiation space is provided between them. Therefore, the heat receiving efficiency from the heat transfer body 13 is excellent and the heat dissipation efficiency from the heat radiating portion to the air is excellent, and the high heat transport performance originally possessed can be maximized. Thereby, the suppression effect with respect to the temperature rise of the photoelectric conversion element 11 increases more.

［４］第４の実施形態について説明する。
図７および図８に示すように、光学レンズ１２と光電変換素子１１との間に筒状体２１が設けられる。筒状体２１は、熱伝導性が良好な部材たとえば銅やアルミニウムにより円筒状に形成され、光学レンズ１２を経た光が入る開口２１ａを軸方向一端に有する。この筒状体２１の内周面の全域に、その開口２１ａに入る光を反射により同筒状体２１の軸方向他端側に導く反射部材（ホモジナイザーともいう）２２が装着される。 [4] A fourth embodiment will be described.
As shown in FIGS. 7 and 8, a cylindrical body 21 is provided between the optical lens 12 and the photoelectric conversion element 11. The cylindrical body 21 is formed in a cylindrical shape from a member having good thermal conductivity, such as copper or aluminum, and has an opening 21a into which light passing through the optical lens 12 enters at one end in the axial direction. A reflection member (also referred to as a homogenizer) 22 that guides light entering the opening 21a to the other axial end of the cylindrical body 21 by reflection is attached to the entire inner peripheral surface of the cylindrical body 21.

光電変換素子１１は、筒状体２１の軸方向他端に、かつ受光面１１ａが開口２１ａに向く状態に、配設される。   The photoelectric conversion element 11 is disposed at the other end in the axial direction of the cylindrical body 21 and in a state where the light receiving surface 11a faces the opening 21a.

筒状体２１の開口２１ａに入る太陽光は、反射部材２２で反射されながら筒状体２１の軸方向他端側に進み、光電変換素子１１の受光面１１ａに照射される。照射される光の強さは、反射部材２２の反射を経ていることにより、受光面１１ａの全域において一定となる。受光面１１ａの一点に強い光が集中しない。   Sunlight entering the opening 21 a of the cylindrical body 21 proceeds to the other axial end of the cylindrical body 21 while being reflected by the reflecting member 22, and is irradiated on the light receiving surface 11 a of the photoelectric conversion element 11. The intensity of the irradiated light is constant throughout the light receiving surface 11a due to the reflection of the reflecting member 22. Strong light does not concentrate on one point of the light receiving surface 11a.

そして、筒状体２１の周面に、熱輸送性能の高い自励振動ヒートパイプ１４が取付けられる。   And the self-excited vibration heat pipe 14 with high heat transport performance is attached to the peripheral surface of the cylindrical body 21.

自励振動ヒートパイプ１４の細管は、筒状体２１の周面に接する位置とその周面から同筒状体２１の径方向に離間する位置との間を往復する状態に巻回されつつ、その巻回が筒状体２１の周方向に沿って螺旋状に繰り返される形状を有する。この細管の各巻回部分は、筒状体２１の周面に接する部分が加熱部、筒状体２１の周面から離間する部分が冷却部となる。この自励振動ヒートパイプ１４の構成そのものは、図２および図３に示した第１の実施形態のものと同じである。   The thin tube of the self-excited vibration heat pipe 14 is wound in a state of reciprocating between a position contacting the circumferential surface of the cylindrical body 21 and a position spaced apart from the circumferential surface in the radial direction of the cylindrical body 21. The winding has a shape that is spirally repeated along the circumferential direction of the cylindrical body 21. As for each winding part of this thin tube, the part which contact | connects the surrounding surface of the cylindrical body 21 becomes a heating part, and the part spaced apart from the surrounding surface of the cylindrical body 21 becomes a cooling part. The structure of the self-excited vibration heat pipe 14 is the same as that of the first embodiment shown in FIGS.

以上のように、筒状体２１および反射部材２２を設けることにより、光電変換素子１１の受光面１１ａに照射される光の強さをその受光面１１ａの全域において一定にすることができる。   As described above, by providing the cylindrical body 21 and the reflecting member 22, the intensity of light irradiated on the light receiving surface 11 a of the photoelectric conversion element 11 can be made constant over the entire area of the light receiving surface 11 a.

光電変換素子１１は熱伝導性が良好な筒状体２１に接しており、その筒状体２１に熱輸送性能の高い自励振動ヒートパイプ１４を取付けているので、光電変換素子１１の熱を効率よく気中に放出できる。これにより、光電変換素子１１の温度上昇を確実に抑制でき、ひいては光電変換素子１１の光電変換効率の低下を回避することができ、常に安定した発電が可能となる。   Since the photoelectric conversion element 11 is in contact with the cylindrical body 21 having good thermal conductivity, and the self-excited vibration heat pipe 14 having high heat transport performance is attached to the cylindrical body 21, the heat of the photoelectric conversion element 11 is absorbed. It can be efficiently released into the air. Thereby, the temperature rise of the photoelectric conversion element 11 can be surely suppressed, and as a result, a decrease in the photoelectric conversion efficiency of the photoelectric conversion element 11 can be avoided, and stable power generation is always possible.

とくに、自励振動ヒートパイプ１４は、筒状体２１の周面に接する位置とその周面から同筒状体２１の径方向に離間する位置との間を往復する状態に巻回されつつ、その巻回が筒状体２１の周方向に沿って螺旋状に繰り返される形状を有し、多数の巻回部分が筒状体２１の周面全体を覆うように接するとともに、それぞれの巻回部分の放熱部が互いに離れてその相互間に十分な放熱空間を確保する構成であるから、伝熱体１３からの受熱効率に優れるとともに放熱部から気中への放熱効率にも優れ、もともと持っている高い熱輸送性能を最大限に発揮することができる。   In particular, the self-excited vibration heat pipe 14 is wound in a state of reciprocating between a position in contact with the circumferential surface of the cylindrical body 21 and a position spaced apart from the circumferential surface in the radial direction of the cylindrical body 21. The winding has a shape that is spirally repeated along the circumferential direction of the cylindrical body 21, and a large number of winding portions are in contact with each other so as to cover the entire circumferential surface of the cylindrical body 21, and each winding portion Since the heat dissipating parts are separated from each other and a sufficient heat dissipating space is ensured between them, the heat receiving efficiency from the heat transfer body 13 is excellent and the heat dissipating efficiency from the heat dissipating part to the air is originally possessed. High heat transport performance can be maximized.
