【発明の詳細な説明】
本発明はアルミニウム箔又はアルミニウム薄板の特性を
利用した太陽熱集熱器の断熱構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat insulating structure for a solar heat collector that utilizes the characteristics of aluminum foil or thin aluminum plates.
従来太陽熱を集熱する平板型集熱器に於ては、ケーシン
グ内に収納された太陽に面する集熱板の裏面側やケーシ
ングの側面内四周に保温材を入れ、熱が外部へ放熱する
のを防止していた。現状ではグラスウール、ロックウー
ル等の保温材が断熱材として使用されている。Conventionally, in flat plate type heat collectors that collect solar heat, heat insulating material is placed on the back side of the heat collecting plate facing the sun housed in the casing and around the four sides of the casing, and the heat is radiated to the outside. It was preventing this. Currently, heat insulating materials such as glass wool and rock wool are used as insulation materials.
ところが上記無機せんい材は耐熱性を考慮して使用する
ため、せんいのバイングーとして有機しを接着したもの
については、接着剤に耐熱性のものを用いる、等の考慮
が払われているが、それにも拘わらず以下の如き欠点を
内蔵していた。。However, since the above-mentioned inorganic fibers are used with heat resistance in mind, consideration has been given to using heat-resistant adhesives when using organic fibers as binder for fibers. Despite this, it had the following drawbacks: .
長期間の使用により、レジン、接着剤等の揮発成分が表
面に配設されたガラスの内面に付着して、くもり現象が
生じ集熱性能の低下を来たした。After long-term use, volatile components such as resin and adhesive adhere to the inner surface of the glass provided on the surface, causing a clouding phenomenon and a decrease in heat collection performance.
長期使用中に雨水が内部に侵入した場合、グラスウール
、ロックウール等は水を吸い易り、容易に水分が抜けな
いため、本来の目的である断熱性能が損なわれることが
あった。又グラスウール、ロックウールは自然にかさが
減小する現象があり、これにより厚さが減小し上表面に
空隙が生じる傾向があり特にバインダーレノンを減らし
たものはこの傾向が強い、。If rainwater enters the interior during long-term use, glass wool, rock wool, etc. tend to absorb water and do not allow moisture to escape easily, so the original purpose of insulation performance may be impaired. In addition, glass wool and rock wool have a phenomenon in which their bulk naturally decreases, which tends to reduce their thickness and create voids on the upper surface, and this tendency is particularly strong in those with reduced binder lenone.
又厚さの減小のみならず集熱器が傾斜して設置されると
、重力と振動で傾斜の下の方へ寄ってくる現象が見られ
、ひどい場合には上部に完全な空間が生じ、断熱性能を
極めて低下するものである。In addition to reducing the thickness, when a heat collector is installed at an angle, gravity and vibration cause it to move toward the bottom of the incline, and in severe cases, a complete space is created at the top. , which extremely deteriorates the insulation performance.
他方バインダーレジンが少ない場合には、鉱物せんいが
ほぐれ易く、遊離せんいが集熱板の上に分散して集熱性
能を阻害するものである。On the other hand, if the amount of binder resin is small, the mineral fibers tend to loosen and the loose fibers are dispersed on the heat collecting plate, impairing the heat collecting performance.
本発明は前記の欠点を除き、なおかつ集熱器に必要な断
熱性をアルミニウムの特性を利用した構造にて解決せん
とするものである。The present invention aims to eliminate the above-mentioned drawbacks and to solve the heat-insulating properties necessary for a heat collector with a structure that utilizes the properties of aluminum.
アルミニウム箔は反射断熱作用により放射伝熱をカット
する効果がある。出願人は実験方法としてアルミニウム
箔３枚を互の間隔を２０咽として平行に立設して２０ｍ
ｎの空気層をａ層設ければ熱貫流率が約０ 、 ｇ Ｋ
ｃａｌ／ｍ２ｈ’ｃ即ちグラスウールｌＩ／咽相当が得
られることを確認した。Aluminum foil has the effect of cutting radiant heat transfer due to its reflective heat insulation effect. As an experimental method, the applicant installed three sheets of aluminum foil in parallel with a distance of 20 m.
If n air layers are provided in a layer, the heat transfer coefficient will be approximately 0, g K
It was confirmed that cal/m2h'c, that is, equivalent to glass wool lI/throat was obtained.
又反射断熱法の他の特徴は熱流の方向により熱貫流率が
変化することである。前記実験は各空気層が上下方向で
、熱流は水平方向の場合である。Another feature of the reflective insulation method is that the heat transmission coefficient changes depending on the direction of heat flow. In the above experiment, each air layer was in the vertical direction, and the heat flow was in the horizontal direction.
の場合でも前記Ｏ６ｇより小さい。Even in this case, it is smaller than the above O6g.
集熱器が犬なる傾斜角にて設置される場合の対流伝熱成
分を小とするためには、アルミニウム箔板に適当間悟に
てｖ形の溝を形成し、この溝にて各空気層を対流方向に
分割して空気の対流を阻止することにより、対流伝熱を
防止して、結果的に集熱板から底板方向への伝熱を防止
出来る。そしてこの様な目的で設けた■形溝は、構造的
にはアルミニウム箔間の空気ス４−スを小さな空気室に
分割し、且つＶ形溝の下端は対面する箔板の平面部に接
し、アルミニウム箔間の間隔をも不動のものとする利点
がある。In order to reduce the convection heat transfer component when the heat collector is installed at a dog slope angle, V-shaped grooves are formed at appropriate intervals in the aluminum foil plate, and each air By dividing the layer in the convection direction to prevent air convection, convective heat transfer can be prevented, and as a result, heat transfer from the heat collecting plate toward the bottom plate can be prevented. The ■-shaped groove provided for this purpose structurally divides the air space between the aluminum foils into small air chambers, and the lower end of the V-shaped groove touches the flat part of the facing foil plate. , there is an advantage that the spacing between the aluminum foils is also fixed.

ルミニウム板を使用し、前記アルミニウム箔により空気

ーシング四周のフレーム材もアルミニウムの押出材を使
用し反射断熱材の機能を付与することが出来る。Furthermore, an aluminum plate with sufficient external strength is used as the bottom plate for the tongue structure, and the aluminum foil used to create an air layer can be replaced, and the frame material around the casing is also made of extruded aluminum, making it reflective. It can provide the function of a heat insulating material.
従来の断熱材に代うるに３０μ〜２００μ厚の光輝性ア

アルミニウム箔の構成による断熱構造では、先に述べた
欠点を凡て解消し、耐久性能の向上に資するものである
。なおアル・ミニラム箔の耐食性を増加するため、アル
マイト処理又はクリアー耐熱樹脂焼付塗装又は透明合成
樹脂にてラミネートをすると一層好ましい。A heat collector configured as described above using a bright aluminum foil with a thickness of 30μ to 200μ instead of the conventional heat insulation material has a heat collection efficiency at an inclination angle of 30° to A OU, but the heat collection efficiency is lower than that of the conventional heat insulation material thickness. Similar results were obtained with a heat collector with 50% glass wool and bar-faced aluminum foil. Furthermore, the heat insulating structure made of aluminum foil eliminates all of the above-mentioned drawbacks and contributes to improved durability. In order to increase the corrosion resistance of the aluminum/minilam foil, it is more preferable to perform an alumite treatment, bake coating with a clear heat-resistant resin, or laminate it with a transparent synthetic resin.

It is between degrees and Bo degrees. Therefore, the arrow side is upward and the opposite side is downward in terms of height. The frame 1 constituting the outer surface of the heat collector is composed of aluminum extruded sections 1a and 1b joined together, and the bottom plate 2 is fixed to the recessed part of the bottom of the frame 1 with screws, etc. In the embodiment, the bottom plate 2 is made of foil. Instead, it is an aluminum plate. Then, an aluminum foil 4 with square grooves 3 formed in the horizontal direction at appropriate pitches is placed on the bottom surface, and an aluminum foil 4' is similarly placed on the top surface of the aluminum foil 4, and the square grooves 3 of the foil 4' The lower end of is in contact with the plane of the IiJ foil 4.

あれば足シる。The heat collecting plate 7 is attached and fixed to the frame 1 by appropriate means. Reference numeral 9 denotes hot water flow paths, which are arranged at appropriate pitches on the heat collecting plate by a conventional method. Further, 9' is a base tube. In a space 12 formed by a frame (not shown), the aluminum foils 4 having the V-shaped grooves are cut into the space and stacked in multiple rows in the same way as if they were placed on the bottom plate. The IC is a protrusion formed on the frame. The structure described above is an embodiment of the above-described configuration, and the space between the heat collecting plate 7 and the bottom plate 2 is formed with an air layer 10 made of aluminum foil and a plate, and each air layer 10.10' is vertically divided into multiple chambers by ■-shaped grooves 3. The division is not limited to the V-shaped groove 3, and any partition that prevents air from convecting in the vertical direction can be used.

さばらず、組立もいとも簡単である。According to the above configuration, the air layer and divided air chamber as a heat insulating structure are extremely stable without being displaced, and the conventional heat insulating material mentioned at the beginning is not used, so the drawbacks of the conventional structure are eliminated. This has solved the problem, making it lightweight, not bulky to store inventory, and extremely easy to assemble.
