しかしながら、上記した従来の樹脂製熱交換器においては、チューブが樹脂製のため、その熱伝導性が悪く、熱交換効率を高めることが難しいといった問題があった。   However, in the conventional resin heat exchanger described above, since the tube is made of resin, the heat conductivity is poor, and it is difficult to increase the heat exchange efficiency.

また、図６に示すように、チューブ２の曲り部９においては、チューブ２内を流通する被冷却媒体から放出された熱がフィン５に熱伝導され難いため、上記した問題は、特に、深刻であった。   Further, as shown in FIG. 6, in the bent portion 9 of the tube 2, since the heat released from the medium to be cooled flowing through the tube 2 is not easily conducted to the fin 5, the above problem is particularly serious. Met.

本発明は、上記課題を解決すべくなされたものであり、熱交換器の放熱性能の向上を図ることのできる樹脂製熱交換器を提供しようとするものである。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a resin heat exchanger capable of improving the heat dissipation performance of a heat exchanger.

本発明は、並設された樹脂製チューブの間に金属製フィンが介装された樹脂製熱交換器であって、前記樹脂製チューブの外面に金属層が形成されていることを特徴とする。   The present invention is a resin heat exchanger in which metal fins are interposed between resin tubes arranged side by side, wherein a metal layer is formed on the outer surface of the resin tubes. .

そして、好ましくは、前記金属層は、前記樹脂製チューブの外面に表面処理を行うことにより形成されている。   Preferably, the metal layer is formed by performing a surface treatment on the outer surface of the resin tube.

また、前記金属製フィンは、対向する前記各金属層にそれぞれ密着可能なように形成された金属製板状部材と、該各板状部材の間に挟装される金属製芯材とから構成され、ハニカム構造を成していてもよい。   Further, the metal fin is composed of a metal plate-like member formed so as to be in close contact with the respective metal layers facing each other, and a metal core member sandwiched between the plate-like members. And may have a honeycomb structure.

さらに、前記芯材は、波形に曲成されていてもよい。   Furthermore, the core material may be bent into a waveform.

以下、図面を参照しつつ、本発明の実施の形態について説明する。ここで、図１は本実施の形態に係る樹脂製熱交換器を拡大して示す断面図、図２は樹脂製熱交換器を拡大して示す断面図、図３は樹脂製熱交換器用を拡大して示す平面図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Here, FIG. 1 is an enlarged sectional view showing a resin heat exchanger according to the present embodiment, FIG. 2 is an enlarged sectional view showing the resin heat exchanger, and FIG. 3 is for a resin heat exchanger. It is a top view which expands and shows.

本実施の形態における樹脂製熱交換器は、並設された多数の樹脂製チューブ１１と、チューブ１１の両端部に接続される樹脂製ヘッダタンク（図示せず）とから概略構成されており、各チューブ１１，１１の間には金属製フィン１２が介装されている。   The resin heat exchanger in the present embodiment is generally configured from a large number of resin tubes 11 arranged in parallel and a resin header tank (not shown) connected to both ends of the tubes 11. Metal fins 12 are interposed between the tubes 11 and 11.

チューブ１１は、扁平形状を成しており、その外面には、メッキや金属蒸着処理等の表面処理により金属層１７が形成されている。   The tube 11 has a flat shape, and a metal layer 17 is formed on the outer surface by a surface treatment such as plating or metal vapor deposition.

フィン１２は、銅またはアルミニウム等の金属製でハニカム構造を成しており、隣接する各チューブ１１，１１の外面にそれぞれ密着可能なように平板状に形成された２枚の金属製板状部材１３，１３と、各板状部材１３，１３の間に挟装される金属製芯材１４とから構成されている。   The fins 12 are made of a metal such as copper or aluminum and have a honeycomb structure, and are two metal plate-like members formed in a flat plate shape so as to be in close contact with the outer surfaces of the adjacent tubes 11, 11. 13 and 13 and a metal core member 14 sandwiched between the plate-like members 13 and 13.

芯材１４は、波形に曲成されており、この曲成部１５を介して各板状部材１３に接合されている。また、好ましくは、各板状部材１３，１３の外面にはそれぞれ接着剤１６，１６が塗布されており、各板状部材１３，１３は接着剤１５，１５を介してチューブ１１，１１の外面に密着可能なようになっている。   The core member 14 is bent into a corrugated shape, and is joined to each plate member 13 via the bent portion 15. Preferably, adhesives 16 and 16 are respectively applied to the outer surfaces of the plate-like members 13 and 13, and the plate-like members 13 and 13 are attached to the outer surfaces of the tubes 11 and 11 via the adhesives 15 and 15. It becomes possible to adhere to.

そして、このような構成を備えた熱交換器において、各チューブ１１内を流通する被冷却媒体と、各チューブ１１，１１の間をフィン１２に接触しながら通過する冷却媒体との間で、熱交換が行われるようになっている。   And in the heat exchanger provided with such a structure, it is between a to-be-cooled medium which distribute | circulates the inside of each tube 11, and the cooling medium which passes between each tube 11 and 11, contacting the fin 12, and heat | fever Exchanges are made.

このように、上記した実施の形態に係る樹脂製熱交換器用においては、樹脂製チューブ１１の外面に金属層１７が形成されており、樹脂製チューブ１１と金属製フィン１２とが熱伝導性の良好な金属材料を介して接触するようになっているため、チューブ１１とフィン１２間の熱伝達性能を向上させることができる。したがって、図２に示すように、チューブ１１の成形精度が良くなく、フィン１２との間に隙間１８が生じたとしても、チューブ１１からフィン１２への熱伝達性能の低下を最小限に抑制することができる。また、図３に示すように、チューブ１１の曲り部１９における熱をフィン１２側に効率良く逃すことができるため、熱交換器の放熱性能を高めることができる。   As described above, in the resin heat exchanger according to the above-described embodiment, the metal layer 17 is formed on the outer surface of the resin tube 11, and the resin tube 11 and the metal fin 12 are thermally conductive. Since it contacts via a favorable metal material, the heat transfer performance between the tube 11 and the fin 12 can be improved. Therefore, as shown in FIG. 2, even if the molding accuracy of the tube 11 is not good and a gap 18 is generated between the tube 12 and the fin 12, a decrease in heat transfer performance from the tube 11 to the fin 12 is minimized. be able to. Moreover, as shown in FIG. 3, since the heat in the bending part 19 of the tube 11 can be efficiently released to the fin 12 side, the heat dissipation performance of the heat exchanger can be enhanced.

さらに、上記した実施の形態に係る樹脂製熱交換器では、金属製フィン１２が板状部材１３及び接着剤１５を介してチューブ１１に密着するため、チューブ１１に対するフィン１２の接触面積が増大し、チューブ１１とフィン１２との間の熱伝達効率を向上させることができる。また、フィン１２がハニカム構造を成しており、樹脂製チューブ１１の補強材としても機能することができるため、チューブを補強するための部材を別個に設ける必要がなくなり、部品点数の削減を図ることも可能となる。   Furthermore, in the resin heat exchanger according to the above-described embodiment, the metal fin 12 is in close contact with the tube 11 via the plate-like member 13 and the adhesive 15, so the contact area of the fin 12 with the tube 11 increases. The heat transfer efficiency between the tube 11 and the fin 12 can be improved. Further, since the fins 12 have a honeycomb structure and can also function as a reinforcing material for the resin tube 11, it is not necessary to separately provide a member for reinforcing the tube, thereby reducing the number of parts. It is also possible.

なお、上記した実施の形態において、フィン１２の芯材１４は波形に曲成されているが、芯材は他の形状を成していてもよく、例えば、図４に示すように、矩形状に曲成させたり、或いは、フィン１２の立上り面及び立下り面にそれぞれ多数のルーバを切り起こし形成させたりする等、各種変更が可能である。   In the above-described embodiment, the core material 14 of the fin 12 is bent in a waveform, but the core material may have other shapes, for example, a rectangular shape as shown in FIG. It is possible to make various changes such as bending the ridges, or cutting and forming a large number of louvers on the rising and falling surfaces of the fins 12, respectively.

また、フィン１２の各板状部材１３，１３の外面には、必ずしも接着剤１６，１６が塗布されている必要はなく、板状部材１３，１３が直接、金属層１７やチューブ１１，１１に密着するように構成されていてもよい。   Moreover, the adhesives 16 and 16 do not necessarily need to be applied to the outer surfaces of the plate-like members 13 and 13 of the fin 12, and the plate-like members 13 and 13 are directly applied to the metal layer 17 and the tubes 11 and 11. You may be comprised so that it may closely_contact | adhere.

さらに、金属製フィン１２は、必ずしも上記したようにハニカム構造を成していなくてもよく、コルゲートフィンやオフセットフィンを使用することもできる。   Furthermore, the metal fins 12 do not necessarily have a honeycomb structure as described above, and corrugated fins and offset fins can also be used.
