Description
本発明は、給湯器／冷水器、特に排他的表現でないが、太陽熱支援ヒートポンプ式給湯器及びその製法に関する。 The present invention relates to a water heater / chiller, and more particularly, but not exclusively, to a solar heat assisted heat pump water heater and a method for making the same.
下記特許文献１及び２は、給湯器の水槽が溶接されたサドル部材と融溶はんだで機械的に固定された管により、給湯器の水槽の全長の実質的な部分に沿って水槽を包囲した太陽熱支援ヒートポンプ式給湯器を開示する。管は、熱媒体流体を搬送して、水槽の表面を加熱することにより水槽内に収容される水を加熱する。水槽に管を取付ける間に、管に錫／鉛／流動酸性のはんだペーストを付着し、その後炉内で水槽を加熱して、はんだを融解し管と水槽との熱伝達接着を完了する。スケールを除去する円筒外面の研磨工程、錫メッキをするための硫酸銅液による予備洗浄工程及び最終洗浄工程、並びに管を緊張状態に維持する工程を含む予備巻付法は、製造サイクルを示し、その後水槽全体を加熱して、はんだを溶融する工程は、製造時間の損失と言える。水槽全体をはんだ融解温度まで加熱するのに要するガス及び付随する冷却期間は、多くの費用と時間とを製造工程に付加する。水槽を十分に洗浄して残留はんだ酸を除去し、ビチューメン塗料で防食処理を施さなければならないので、更なる時間遅延と経費が必要となる。また製造工程には、水槽に管を巻き付けているとき、水槽から約６００mmだけ管を変形し、緊張させる装置を有し、この装置は、管がローラから離れるときに管が自由に捩れるので、水槽と管との接触損失を招来する可能性がある。
従って、本発明の目的は、特許文献１及び２に記載される技術的着想を改善する給湯器を提供することである。
Accordingly, an object of the present invention is to provide a water heater that improves the technical idea described in
本発明の他の目的は、特許文献１及び２に記載されるものよりも簡素な構造を有する給湯器を提供することにある。
Another object of the present invention is to provide a water heater having a simpler structure than those described in

In another embodiment of the invention, the heat transfer material is an uncured heat transfer paste. In yet another embodiment, the at least one stretch wrap film layer hermetically surrounds the thermally conductive material. It is preferred to stretch the tube over at least 85% of the length of the aquarium.
本発明の他の実施の形態では、管の長さと同じ広さで伝熱性材料を管又は水槽の壁部の一方に取り付けて、管と水槽の壁部とを熱伝達接触可能に水槽の壁部の周囲に管を捲回し、水槽の壁部と管の周りに少なくとも１つの材料層を緊密に包装する。 In another embodiment of the present invention, the heat transfer material is attached to one of the pipe or the wall of the aquarium with the same width as the length of the pipe, and the wall of the aquarium is capable of heat transfer contact between the pipe and the aquarium wall. The tube is wound around the part and at least one material layer is tightly wrapped around the aquarium wall and the tube.

In order to understand the present invention more easily and to clarify practical effects, the accompanying drawings will be described.
A water heater (10) comprising a water tank (12) having a normally concave or convex bottom wall (14), a convex top wall (16) and a cylindrical side wall (18) is shown in the drawing. The water tank (12) can be formed of a suitable heat transfer material or heat transfer material mainly composed of metal or alloy. In a preferred embodiment, the aquarium (12) is made of steel, glass-lined steel, stainless steel, copper or other suitable material. A cold water inlet (not shown) is provided adjacent to the bottom wall (14), and a hot water outlet (not shown) is provided adjacent to the top wall (16). The water tank (12) is held in a cylindrical case (20) sealed by a lid (22). A heat insulating foam material (not shown) is filled between the water tank (12) and the cylindrical case (20) and the lid (22). The tube (24) is wrapped around the side wall (18) and has an inlet (26) and an outlet (28). Further, it is preferable to form the pipe (24) from any appropriate heat conductive or heat transfer material mainly composed of metal or alloy. In a preferred embodiment, the tube (24) is made of copper for flexibility and corrosion resistance. The tube (24) usually extends more than 85% of the length of the side wall (18). Usually, refrigerant (not shown) containing R22 (Freon HCFC) and R12 (Freon HCF) equivalents is supplied through the pipe (24) to heat the side wall (18), and the water in the water tank (12) is heated. The A pipe | tube (24) is a part of solar heat assistance heat pump type water heater, and is described in
図２及び図３は、側壁(18)に管(24)を取り付けた状態の断面図を示す。管(24)は、平板な底面(30)を有するＤ形状（図示）、楕円形状又は他の閉鎖形状の断面を有し、側壁(18)に取付ける前に円形断面管を変形させるか又は図示のように成形ローラ圧縮により側壁(18)に押付けて成形する。管(24)は、底面(30)に付着されかつ管(24)から側壁(18)への熱伝達を最大にする熱伝導性ペースト(32)を有する。管(24)は、圧縮力により側壁(18)及び給湯器(10)の周囲に包装された材料層に押付けられて圧縮力が維持される。通常、延伸包装フィルムの２層(34,36)が最初に取付けられる。延伸包装フィルムは、適切に形成されたポリエチレンフィルムが好ましい。次の層(38)は、給湯器(10)へ熱を逆に反射する反射器として作用するアルミニウム箔である。最後に、更なる４つの延伸包装フィルム層(40,42,44,46)が層(38)を覆う。材料層の数及び積層状態は、必要に応じて適宣変更できるのであって、記載した材料層の数及び積層状態には限定されない。延伸包装フィルムは、紫外線光に暴露されなければ、フィルムの変性は生じない。材料層の包装及び圧縮状態により、熱伝導性ペースト(32)の保全性を確保しかつ空気循環又は熱循環による乾燥が生じないように、熱伝導性ペーストを封止する。熱伝導性ペースト(32)は、包装しなければ空気に露出され、時間とともに乾燥し脆くなる。熱循環もこの崩壊を促進する。崩壊により、管断面(25)と側壁(18)との間の熱伝導接触効率を低減する。包装は、空気から熱伝導性ペースト(48)を密封してあらゆる乾燥又は肥大化を回避する事ができる。 2 and 3 are sectional views showing a state in which the pipe (24) is attached to the side wall (18). The tube (24) has a D-shaped (shown), oval or other closed cross-section with a flat bottom surface (30) to deform or show a circular cross-section tube before attaching to the side wall (18). In this way, the molding roller is pressed against the side wall (18) for molding. The tube (24) has a thermally conductive paste (32) attached to the bottom surface (30) and maximizing heat transfer from the tube (24) to the side wall (18). The pipe (24) is pressed against the material layer wrapped around the side wall (18) and the water heater (10) by the compressive force, and the compressive force is maintained. Usually, two layers (34, 36) of stretch wrapping film are attached first. The stretched packaging film is preferably a suitably formed polyethylene film. The next layer (38) is an aluminum foil that acts as a reflector that reflects heat back to the water heater (10). Finally, four additional stretch wrapping film layers (40, 42, 44, 46) cover layer (38). The number of material layers and the lamination state can be appropriately changed as necessary, and are not limited to the number of material layers and the lamination state described. The stretched packaging film does not undergo film modification unless exposed to ultraviolet light. The heat conductive paste is sealed so as to ensure the integrity of the heat conductive paste (32) and prevent drying by air circulation or heat circulation depending on the packaging and compression state of the material layer. The heat conductive paste (32) is exposed to air unless it is packaged, and becomes dry and brittle over time. Thermal cycling also promotes this collapse. The collapse reduces the heat transfer contact efficiency between the tube cross section (25) and the side wall (18). The packaging can seal the thermally conductive paste (48) from the air to avoid any drying or enlargement.
図４は、側壁(18)に管(24)を取付ける一連の工程を示す。本実施の形態では、管(24)は、ローラ圧縮により形成される。第１に、直径１０mmの管断面(25)を有する一定長さの管(24)は、側壁(18)の所定の位置に配置されて保持される。側壁(18)上に押付ける管断面(25)の直下に、供給機（図示せず）から例えば３mmの細長い熱伝導性ペースト（ビード）(48)を水平に回転する水槽(12)上に配置する。本実施の形態に使用する細長い熱伝導性ペースト(48)は、ボスティック熱伝導密封剤#1128又は#5603として公知である。本実施の形態では細長い熱伝導性ペースト(48)は、非接着性の油状材料であるが、接着性材料でも同様に使用できる。第２に、管断面(25)は、側壁(18)に対してＤ形状（図示）又は楕円形に圧縮されて、細長い熱伝導性ペースト(48)を扁平に潰し、均等な厚みで管(24)の底面(30)に熱伝導性ペースト(48)を取付ける。熱伝導性ペースト(48)は、通常は底面(30)の下で扁平に潰される。軸(66)周りに回転する圧縮ローラ(64)により、管断面(25)を側壁(18)上に押し付けてＤ形又は楕円形断面に管(24)に変形させる。第３に、例えば直径４〜６mmの細長い一対の並行な熱伝導性ペースト(50,52)が、側壁(18)上に管(24)の両端へ取付けられる。この過程により、熱伝導域の面積を増加することができる。最終過程では、細長い熱伝導性ペースト(50,52)を接合隅部(56)に充填して最大の熱伝達率を得ることができる。管(24)は、通常側壁(18)の底部(14)から頂部(16)に捲回されて保持されるが付着されず、通常樹脂製のブラケット（図示せず）により側壁(18)に管(24)の両端が留められる。水槽(12)の側壁(18)の周囲に緊張して捲回される非延伸接合材により、ブラケットは、側壁(18)に保持される。管(24)が水槽(12)の頂壁(16)付近まで捲回されると、螺旋状の延伸包装フィルムを形成しながら、管(24)は、安定して固定される。通常上半分(60)側より下半分(58)側をより緊密に管(24)が螺旋状に捲回される。例えば、可変ピッチで漸進的に螺旋を増加する捲回法、個別の２条捲回法、重畳捲回法又は、介在物挿入捲回法等他の捲回法を使用することができる。給湯器(10)の構造を完成するには、図２及び図３について説明したように、その後層(34〜46)が付着される。包装された捲回体全体で管(24)を曲げて出口(28)が形成される。 FIG. 4 shows a series of steps for attaching the tube (24) to the side wall (18). In the present embodiment, the pipe (24) is formed by roller compression. First, a fixed length tube (24) having a tube cross section (25) with a diameter of 10 mm is placed and held in place on the side wall (18). Immediately below the pipe cross section (25) pressed onto the side wall (18), for example, a 3 mm long and thin thermal conductive paste (bead) (48) from a feeder (not shown) is placed on the horizontally rotating water tank (12). Deploy. The elongated heat conductive paste (48) used in the present embodiment is known as Bostic heat conductive sealant # 1128 or # 5603. In the present embodiment, the elongated heat conductive paste (48) is a non-adhesive oily material, but an adhesive material can be used as well. Secondly, the tube cross section (25) is compressed into a D shape (shown) or an ellipse with respect to the side wall (18), flattening the elongated heat conductive paste (48) into a flat shape with a uniform thickness ( Attach the thermal conductive paste (48) to the bottom (30) of 24). The heat conductive paste (48) is usually flattened under the bottom surface (30). A compression roller (64) rotating about an axis (66) presses the tube cross section (25) onto the side wall (18) and deforms it into a tube (24) into a D or oval cross section. Thirdly, a pair of elongate parallel heat conductive pastes (50, 52), for example 4-6 mm in diameter, are mounted on the side walls (18) at both ends of the tube (24). Through this process, the area of the heat conduction region can be increased. In the final process, the elongated heat conductive paste (50, 52) can be filled into the joint corner (56) to obtain the maximum heat transfer coefficient. The pipe (24) is usually wound and held from the bottom (14) to the top (16) of the side wall (18) but is not attached, and is usually attached to the side wall (18) by a bracket made of resin (not shown). Both ends of the tube (24) are fastened. The bracket is held on the side wall (18) by the non-stretched bonding material that is wound around the side wall (18) of the water tank (12). When the pipe (24) is wound up to the vicinity of the top wall (16) of the water tank (12), the pipe (24) is stably fixed while forming a spiral stretched packaging film. Usually, the tube (24) is spirally wound more tightly on the lower half (58) side than on the upper half (60) side. For example, other winding methods such as a winding method in which the spiral is gradually increased at a variable pitch, an individual two-strand winding method, a superimposed winding method, or an inclusion insertion winding method can be used. To complete the structure of the water heater (10), the layers (34-46) are then deposited as described with reference to FIGS. The outlet (28) is formed by bending the tube (24) over the entire wound body.
図５は、Ｄ型断面の管(24)の変形実施例の形態を示す。本実施の形態では、管(24)は、断面中央部(68)で窪んで膨出部(70,72)を有する繭形断面となる。繭形断面により、管(24)の両縁部及び接合隅部(56)への熱量の集中を増加し、管(24)の断面積内の冷媒速度を上げて、冷媒油の帰還量及び信頼性を向上する。 FIG. 5 shows a variant embodiment of the tube (24) with a D-shaped cross section. In the present embodiment, the tube (24) has a bowl-shaped cross section that is recessed at the central section (68) of the cross section and has bulged portions (70, 72). The saddle-shaped cross section increases the concentration of heat on both edges and junction corner (56) of the pipe (24), increases the refrigerant speed in the cross-sectional area of the pipe (24), Improve reliability.
前記好適な実施の形態は、特許文献１及び２に開示される技術と比較して、給湯器(10)の構造を簡素化するものである。比較試験では前記好適な実施の形態は、特許文献１及び２に示される給湯器(10)よりも性能が２８%増加し、中温から高温領域では圧縮器と水との温度比が１０%以上減少した。前記性能改善により、直接かつ効率的に圧縮器寿命を増加してかつ作動騒音出力を低減することが出来る。前記好適な実施の形態は、少なくとも２８%より高い成績係数を示した。２４時間の熱損失とそれ以降の熱回収を考慮すると、この値は、３８%まで増加した。
The preferred embodiment simplifies the structure of the water heater (10) as compared with the techniques disclosed in
好適な実施の形態では、給湯器(10)としての使用例を記載したが、管(24)内の媒体が熱媒体でなく冷媒を使用する逆サイクル冷凍により冷やして水を水槽(12)により保持することもできる。 In the preferred embodiment, an example of use as the water heater (10) has been described.However, the medium in the pipe (24) is cooled by reverse cycle refrigeration using a refrigerant instead of a heat medium, and water is cooled by a water tank (12). It can also be held.
