Description
本発明は、自動車用や建設機械用の油や燃料等の冷却管、居住用空間の温湿度を調整する空調機、食品の鮮度を保って保存する冷凍冷蔵庫、化学設備の反応塔等に広く使用されるフィンチューブに係るものである。 The present invention is widely used in oil and fuel cooling pipes for automobiles and construction machinery, air conditioners that adjust the temperature and humidity of living spaces, refrigerators that preserve food freshness, and reaction towers in chemical facilities. This relates to the fin tube used.
従来より、特許文献1及び2に記載の発明の如く、亜鉛めっきやクロメート皮膜等の防食メッキを施した鋼管や、アルミ管等の金属管の外周面に、押出成型法によりポリアミド(PA)、ポリプロピレン(PP)、ポリエチレン(PE)等の熱可塑性の樹脂皮膜層を設けたフィンチューブが存在する。このような従来のフィンチューブは、樹脂皮膜層の衝撃吸収力や耐水性、耐薬品性などにより、飛び石等による防食メッキ層や金属管の破損を防ぐとともに、泥はねや薬品等による金属管の酸化を防止し、フィンチューブの耐食性を高めるものであった。しかしながら、上記特許文献1及び2に記載のフィンチューブは、耐衝撃性や耐食性を高めるために樹脂皮膜層を肉厚に形成しているので、放熱特性の点で問題があり、フィンチューブの内外を流通する流体相互の熱交換を効率的に行うのは困難であった。 Conventionally, as in the inventions described in Patent Documents 1 and 2, polyamide (PA), an extrusion molding method, is used on the outer peripheral surface of a steel pipe, such as a zinc pipe or a chromate film, or a metal pipe such as an aluminum pipe. There is a fin tube provided with a thermoplastic resin film layer such as polypropylene (PP) or polyethylene (PE). Such conventional fin tubes prevent damage to the anticorrosion plating layer and metal pipes due to stepping stones, etc., due to the impact absorption capacity, water resistance, chemical resistance, etc. of the resin coating layer, and metal pipes due to mud splashes and chemicals. This prevented the oxidation of the fin tube and improved the corrosion resistance of the fin tube. However, the fin tubes described in Patent Documents 1 and 2 have a problem in terms of heat dissipation characteristics because the resin film layer is formed thick in order to improve impact resistance and corrosion resistance. It has been difficult to efficiently exchange heat between fluids that circulate.
そこで、特許文献3に記載の発明の如く、金属管の外周面に耐食性の高い樹脂皮膜層を設けるとともに、この樹脂皮膜層の外周面に伝熱体を設け、更に伝熱体の外周面に樹脂製のフィン部材を螺旋状に巻き回したものが公知となっている。
しかしながら、特許文献3に示す如きフィン部材は表面が平滑であるため、フィンチューブの放熱性を更に高めるためには、より広い表面積が必要となっていた。また、このように形成したフィン部材の表面に流れる流体が整流されるため、このフィン部材の表面に存在する境界層が厚くなり、放熱による熱交換機能を十分発揮することが困難となっていた。 However, since the fin member as shown in Patent Document 3 has a smooth surface, a larger surface area is required to further improve the heat dissipation of the fin tube. Further, since the fluid flowing on the surface of the fin member formed in this way is rectified, the boundary layer existing on the surface of the fin member becomes thick, and it has been difficult to sufficiently exert the heat exchange function by heat dissipation. .
そこで、本発明は上記の如き課題を解決しようとするものであって、高い耐食性を有するとともに、放熱性を高めるのに十分な表面積と多数の長いエッヂを形成したフィン部材を配設したフィンチューブを得ようとするものである。 Accordingly, the present invention is intended to solve the above-described problems, and has a high corrosion resistance and a fin tube provided with a fin member having a surface area sufficient to enhance heat dissipation and a large number of long edges. Is going to get.
本発明は上述の如き課題を解決するため、一本の線材を螺旋状に巻回すとともに、管部材への巻回時に管部材側に配置される螺旋の外側部に、ベルト材の一面を固定して形成したフィン部材を、管部材の外周面に少なくとも一層被覆した前記樹脂被膜層の表面に上記ベルト材の他面を面接触させて、管部材に巻き回したものである。 In order to solve the above-mentioned problems, the present invention winds a single wire in a spiral shape, and fixes one surface of the belt material to the outer portion of the spiral arranged on the tube member side when wound around the tube member. The fin member formed as described above is wound around the pipe member by bringing the other surface of the belt material into surface contact with the surface of the resin coating layer covering at least one layer of the outer peripheral surface of the pipe member .
また、フィン部材は、樹脂被膜層の表面に螺旋状に巻き回したものであっても良い。 The fin member may be spirally wound around the surface of the resin coating layer.
また、フィン部材は、樹脂被膜層の表面に環状に巻き回すとともに、管部材の軸方向に間隔を設けて複数個配設したものであっても良い。 In addition, the fin member may be wound around the surface of the resin coating layer in a ring shape, and a plurality of fin members may be disposed at intervals in the axial direction of the tube member.
また、フィン部材は、巻回時に管部材側に配置される螺旋の内側部に、内側ベルト材を配置したものであっても良い。 Further, the fin member may be one in which an inner belt material is arranged on the inner side of a spiral arranged on the tube member side during winding.
また、フィン部材は、巻回時に管部材側に配置される螺旋の内側部に、内側固定線材を配置したものであっても良い。 Further, the fin member may be one in which an inner fixed wire is disposed on the inner side of a spiral disposed on the tube member side during winding.
本発明は上述の如く構成したものであって、管部材の外周面に少なくとも一層の樹脂被膜層を被覆することにより、飛び石などに対する管部材の耐食性を高めることが可能となる。また、一本の線材を螺旋状に巻き回して形成したフィン部材を前記樹脂被膜層に配設することにより、フィン部材の表面積を容易に広くすることができるとともに、多数の長いエッヂが形成されて管外側の流体の流れに大きな乱れや渦を発生させて境界層を剥離されるものとなる。そのため、上記の広い表面積と多数の長いエッヂとによりフィンチューブの放熱性や吸熱性を高めることが可能となる。 The present invention is configured as described above. By coating at least one resin coating layer on the outer peripheral surface of the pipe member, the corrosion resistance of the pipe member against a stepping stone or the like can be improved. In addition, by disposing the fin member formed by spirally winding a single wire on the resin coating layer, the surface area of the fin member can be easily increased and a large number of long edges are formed. As a result, a large turbulence or vortex is generated in the flow of fluid outside the pipe, and the boundary layer is peeled off. Therefore, it is possible to improve the heat dissipation and heat absorption of the fin tube by the large surface area and the many long edges.
本発明の実施例1を図1於いて説明すると、(1)はフィン部材である。そしてこのフィン部材(1)は、一本の線材(2)を長方形の螺旋状に巻回して形成した螺旋部材(18)を備えて成るものであって、この螺旋部材(18)の螺旋の外側部(8)を、薄板状で長尺なベルト材(13)の一面に一端から他端まで連続してろう付け等により固定している。尚、上記螺旋部材(18)は、ステンレス、アルミニウム、アルミニウム基合金、銅、銅基合金、鉄等の線材(2)にて、扁平な長方形状に巻き回して形成している。 A first embodiment of the present invention will be described with reference to FIG. 1. (1) is a fin member . The fin member (1) includes a spiral member (18) formed by winding a single wire (2) into a rectangular spiral shape. The outer part (8) is fixed to one surface of a thin and long belt material (13) continuously from one end to the other end by brazing or the like. The spiral member (18) is formed by winding it into a flat rectangular shape with a wire (2) such as stainless steel, aluminum, an aluminum base alloy, copper, a copper base alloy, or iron.
また、このフィン部材(1)を配置する管部材(3)は、ステンレス、アルミニウム、アルミニウム基合金、銅、銅基合金、鉄等にて形成した金属管(7)の表面に、亜鉛又は亜鉛系のメッキを施して第1メッキ層(4)を形成するとともに、この第1メッキ層(4)の表面に、6価、好ましくは3価のクロメート処理あるいは上層メッキを施して第2メッキ層(5)を形成している。そして、この管部材(3)の第2メッキ層(5)の表面に、押出成形装置等により樹脂被膜層(6)を被覆している。 The pipe member (3) for disposing the fin member (1) is made of zinc or zinc on the surface of a metal pipe (7) formed of stainless steel, aluminum, aluminum base alloy, copper, copper base alloy, iron or the like. The first plating layer (4) is formed by applying a system plating, and the surface of the first plating layer (4) is subjected to a hexavalent, preferably trivalent chromate treatment or upper plating to form a second plating layer. (5) is formed. The surface of the second plating layer (5) of the pipe member (3) is covered with a resin coating layer (6) by an extrusion molding apparatus or the like.
この樹脂被膜層(6)は、本実施例1及び以下の実施例2、3ではポリアミド12等のポリアミド(PA)、ポリプロピレン(PP)、ポリエチレン(PE)等で形成したものであって、管部材(3)の外周面に1層のみ配置している。尚、本発明の樹脂皮膜層(6)はPA、PP、PE等を単体で使用する他に、これらの樹脂を適宜複合させて使用することも可能である。また、他の異なる実施例では樹脂皮膜層(6)を1層のみに限らず、複数層管部材(3)に配置することも可能である。このように、管部材(3)の外周面を樹脂皮膜層(6)にて被覆することにより、管部材(3)の耐食性をより高めることが可能となる。 The resin coating layer (6), the polyamide of 12 and polyamide in the present embodiment 1 and the following examples 2,3 (PA), polypropylene (PP), be those formed of polyethylene (PE) or the like, Only one layer is arranged on the outer peripheral surface of the pipe member (3). The resin film layer (6) of the present invention can be used by appropriately combining these resins in addition to using PA, PP, PE and the like alone. In other different embodiments, the resin film layer (6) is not limited to a single layer, but can be disposed on a multi-layer pipe member (3). Thus, by covering the outer peripheral surface of the pipe member (3) with the resin film layer (6), the corrosion resistance of the pipe member (3) can be further improved.
尚、本実施例1及び以下の実施例2、3では、第1メッキ層の表面にクロメート処理を行うことにより第2メッキ層(5)を形成しているが、他の異なる実施例では、クロメート処理に代わって塗膜処理を行うことにより第2メッキ層(5)を形成しても良い。また、第1メッキ層(4)としてニッケル又はニッケル基合金をメッキし、第2メッキ層(5)として亜鉛又は亜鉛基合金をメッキしても良いし、更にクロメート処理や樹脂被膜層(6)との密着性を向上させるために、エポキシプライマー等を設けても良い。 In the present embodiment 1 and the following Examples 2 and 3, by performing chromate treatment to the surface of the first plating layer is to form a second plated layer (5), in other different embodiments The second plating layer (5) may be formed by performing a coating treatment instead of the chromate treatment. Further, nickel or a nickel base alloy may be plated as the first plating layer (4), and zinc or a zinc base alloy may be plated as the second plating layer (5). Further, the chromate treatment or the resin coating layer (6) may be used. An epoxy primer or the like may be provided in order to improve the adhesion to the substrate.
また、本実施例1、及び以下の実施例2、3では、上記の如く金属管(7)に第1メッキ層(4)及び第2メッキ層(5)を設けて管部材(3)を形成しているが、他の異なる実施例では、第1メッキ層(4)及び第2メッキ層(5)等を設けずに、金属管(7)のみから成る管部材(3)の外周面に樹脂皮膜層(6)を直接被覆したものであっても良い。このように第1メッキ層(4)や第2メッキ層(5)を設けない管部材(3)を使用した場合であっても、管部材(3)の外周面に樹脂皮膜層(6)を被覆することにより耐食性に優れた製品を得ることができる。 Further, in the present embodiment 1, and the following Examples 2 and 3, the metal tube as the first plating layer (7) (4) and the second plating layer (5) is provided tubular member (3) However, in other different embodiments, the outer periphery of the pipe member (3) consisting only of the metal pipe (7) without providing the first plating layer (4) and the second plating layer (5), etc. The resin film layer (6) may be directly coated on the surface. Thus, even when the pipe member (3) not provided with the first plating layer (4) or the second plating layer (5) is used, the resin film layer (6) is formed on the outer peripheral surface of the pipe member (3). The product excellent in corrosion resistance can be obtained by coating.
そして、このように螺旋部材(18)を固定したベルト材(13)の他面を樹脂皮膜層(6)の表面に面接触させた状態で、ベルト材(13)を引っ張りながら管部材(3)に螺旋状に巻き回す。これにより、フィン部材(1)に形成されたピン状片(10)が、樹脂皮膜層(6)の表面に螺旋状に複数個連続して配設されるものとなる。そのため、この複数のピン状片(10)の存在によって、フィン部材(1)の表面積が広くなるとともに多数の長いエッヂが形成され、管部材(3)の管外側の流体の流れに大きな乱れを発生させて境界層を剥離させることが可能となるため、放熱性を高めることが可能となる。 The pipe member (3) is pulled while pulling the belt member (13) in a state where the other surface of the belt member (13) to which the spiral member (18) is fixed is brought into surface contact with the surface of the resin film layer (6). ) Spirally. Thus, full fin member (1) in the form made a pin-like piece (10) becomes as being plural continuously helically disposed on the surface of the resin film layer (6). Therefore, the presence of the plurality of pin-like pieces (10) increases the surface area of the fin member (1) and forms a large number of long edges, greatly disturbing the flow of fluid outside the pipe of the pipe member (3). Since it can be generated and the boundary layer can be peeled off, heat dissipation can be improved.
そして、上記フィン部材(1)のベルト材(13)を管部材(3)に形成した樹脂皮膜層(6)の表面に密着させた状態で、フィン部材(1)を管部材(3)に巻き回している。そして、ベルト材(13)を引っ張りながらフィン部材(1)を管部材(3)に巻き回すことにより、管部材(3)に設けた樹脂皮膜層(6)の弾性力によってベルト材(13)が樹脂被膜層(6)に若干食い込むものとなる。そのため、接着などの特別な固着手段を要さずにベルト材(13)の他面を樹脂皮膜層(6)の表面に強く密接配置することができ、フィン部材(1)を管部材(3)に安定した状態で配設することが可能となるとともに、管部材(3)からの熱を、樹脂皮膜層(6)を介してより確実にフィン部材(1)に伝達することが可能となる。The fin member (1) is attached to the pipe member (3) in a state where the belt member (13) of the fin member (1) is in close contact with the surface of the resin film layer (6) formed on the pipe member (3). It is winding. Then, the belt member (13) is wound by the elastic force of the resin film layer (6) provided on the pipe member (3) by winding the fin member (1) around the pipe member (3) while pulling the belt material (13). Slightly bites into the resin coating layer (6). Therefore, the other surface of the belt material (13) can be strongly and closely arranged on the surface of the resin film layer (6) without requiring any special fixing means such as adhesion, and the fin member (1) is connected to the pipe member (3 ) In a stable state, and heat from the pipe member (3) can be more reliably transmitted to the fin member (1) through the resin film layer (6). Become.
また、本実施例1では、ベルト材(13)の他面が樹脂皮膜層(6)に面接触するため、この接触部(12)の樹脂皮膜層(6)への食い込みは均一なものとなる。そのため、フィン部材(1)を管部材(3)に、より安定して配置することが可能となる。また、上記の如く螺旋部材(18)にベルト材(13)を予め固定してフィン部材(1)を形成することにより、製造時の作業性が良くなり、作業を効率的に行うことが可能となる。 Further, in Example 1, since the other surface of the belt material (13) is in surface contact with the resin film layer (6), the contact portion (12) bites into the resin film layer (6) uniformly. Become. Therefore, it becomes possible to arrange the fin member (1) on the pipe member (3) more stably. In addition, as described above, the belt member (13) is fixed in advance to the spiral member (18) to form the fin member (1), thereby improving the workability at the time of manufacture and enabling the work to be performed efficiently. It becomes.
また、前記実施例1では、螺旋部材(18)の螺旋の外側部(8)にベルト材(13)を配置しているが、本発明の実施例2では、螺旋部材(18)の螺旋の内側部(14)に薄板状で長尺に形成した内側ベルト材を配置している。即ち、まず、巻回形状が長方形の螺旋部材(18)の螺旋の内側部(14)に、予め内側ベルト材を配置し、この内側ベルト材を、螺旋部材(18)の内側部(14)に沿って溶接又はろう付けにて固定する。そして次に、螺旋部材(18)の外側部(8)を樹脂皮膜層(6)の表面に直接接触させた状態で、螺旋部材(18)を管部材(3)の外周面に螺旋状に巻き回す。 Further, in the embodiment 1, the helix of the helical member (18) is in the outer portion (8) is arranged a belt material (13), in the second embodiment of the present invention, the helical member (18) An inner belt member formed in a thin plate shape and an elongated shape is disposed on the inner portion (14) of the spiral. That is, first, an inner belt material is arranged in advance on the spiral inner portion (14) of the spiral member (18) having a rectangular winding shape, and this inner belt material is placed on the inner portion (14) of the spiral member (18). And fixed by welding or brazing. Next, the spiral member (18) is spirally formed on the outer peripheral surface of the pipe member (3) in a state where the outer portion (8) of the spiral member (18) is in direct contact with the surface of the resin film layer (6). Wind it around.
このように内側ベルト材を螺旋部材(18)の螺旋の内側部(14)に配置して管部材(3)に巻き回すことにより、フィン部材(1)が管部材(3)に、より強固に固定されるものとなる。そのため、フィン部材(1)を安定した状態で管部材(3)に配置することが可能となる。また、製造時の作業性が良くなり、作業を効率的に行うことが可能となる。 Thus, the fin member (1) is more firmly attached to the pipe member (3) by arranging the inner belt member on the inner part (14) of the spiral of the spiral member (18) and winding it around the pipe member (3). It will be fixed to. Therefore, it becomes possible to arrange | position the fin member (1) to a pipe member (3) in the stable state. In addition, workability at the time of manufacture is improved, and work can be performed efficiently.
また、前記実施例2では、フィン部材(1)の螺旋の内側部(14)に内側ベルト材を配置しているが、本発明の実施例3では、巻回形状を扁平な長円状とした螺旋部材(18)にて形成したフィン部材(1)の螺旋の内側部(14)に、内側固定線材を配置している。このように、フィン部材(1)の螺旋の内側部(14)に内側固定線材を配置して管部材(3)に巻き回すことにより、前記実施例2の場合と同様に、フィン部材(1)を管部材(3)に、より強固に固定配置することができる。また、製造時の作業性が良くなり、作業を効率的に行うことが可能となる。 Further, in the embodiment 2, but are disposed inside the belt member to the inside of the helical fin members (1) (14), in the third embodiment of the present invention, flat oval winding shape An inner fixed wire is arranged on the inner side (14) of the spiral of the fin member (1) formed by the spiral member (18) having a shape. Thus, by turning up the inner fixed wire placement to the tube member (3) to the inner portion of the spiral fin members (1) (14), as in the case of Example 2, the fin member ( 1) can be fixedly arranged on the pipe member (3) more firmly. In addition, workability at the time of manufacture is improved, and work can be performed efficiently.
尚、他の異なる実施例においては、上記実施例1〜3で使用した樹脂皮膜層(6)にカーボンナノファイバーを含有させることにより、伝熱性を更に高めることが可能となるので、更に好ましいものとなる。また、フィン部材(1)を接着材により管部材(3)の樹脂皮膜層(6)に固定することも可能である。この場合には、上記接着材にカーボンナノファイバーを含有させることにより、伝熱性を更に高めることができるため、更に好ましいものとなる。また、このように接着材を使用することにより、当該接着材を介して、樹脂皮膜層からの熱がフィン部材に伝わりやすいものとなるため、伝熱性を更に向上させることが可能となる。 In addition, in another different Example, since it becomes possible to further improve heat conductivity by containing a carbon nanofiber in the resin film layer (6) used in the said Examples 1-3 , it is still more preferable. It becomes. Moreover, it is also possible to fix the fin member (1) to the resin film layer (6) of the pipe member (3) with an adhesive. In this case, since heat conductivity can be further improved by including carbon nanofibers in the adhesive, it is more preferable. Further, by using the adhesive as described above, heat from the resin film layer is easily transmitted to the fin member via the adhesive, so that it is possible to further improve the heat conductivity.
また、他の異なる実施例においては、上記実施例1〜3に示す如くフィン部材(1)を管部材(3)に巻き回した後、樹脂皮膜層(6)を、この樹脂皮膜層(6)を構成する樹脂のガラス転移点以上で融点未満の温度に加熱することにより軟化させて、フィン部材(1)を樹脂皮膜層(6)に更に深く食い込ませて融着し、フィン部材(1)の接触部(12)と樹脂皮膜層(6)との接触面積をより広げると、更に好ましいものとなる。また、フィン部材(1)の巻き回し後に、このフィン部材(1)と接触している部分の樹脂皮膜層(6)を、当該樹脂の融点以上に加熱することにより部分的に溶融させて、フィン部材(1)を樹脂皮膜層(6)に融着させると、フィン部材(1)の接触部(12)と樹脂皮膜層(6)との接触面積が広がるとともに、フィン部材(1)を樹脂皮膜層(6)に、より強固に固定することが可能となるため、更に好ましいものとなる。但し、融点以上に加熱して融着する場合には、製造時に溶融した樹脂が流れ出して液だれが生じる可能性があるため、注意を要する。 In another different embodiment, after the fin member (1) is wound around the pipe member (3) as shown in the first to third embodiments, the resin film layer (6) is replaced with the resin film layer (6 ) Is softened by heating to a temperature above the glass transition point of the resin constituting the resin and below the melting point, and the fin member (1) is deeply penetrated into the resin film layer (6) to be fused, and the fin member (1 The contact area between the contact portion (12) and the resin film layer (6) is further increased. In addition, after winding the fin member (1), the resin film layer (6) in contact with the fin member (1) is partially melted by heating to a temperature higher than the melting point of the resin, When the fin member (1) is fused to the resin film layer (6), the contact area between the contact portion (12) of the fin member (1) and the resin film layer (6) is increased, and the fin member (1) is This is more preferable because it can be more firmly fixed to the resin film layer (6).
