Description

本発明は、熱交換器に関し、特に、ルーバの強度及び剛性を最大限に高めるようリブがルーバに形成された熱交換器用のルーバ付きフィンに関する。   The present invention relates to a heat exchanger, and more particularly to a louvered fin for a heat exchanger in which ribs are formed on the louver so as to maximize the strength and rigidity of the louver.

空冷式フィン形熱交換器は、非常によく知られている。熱交換器は、種々の作動流体、例えば、エンジン冷却剤、例えばエンジン潤滑油、空調冷媒、及び自動変速機油の温度を変更するために用いられる。熱交換器は、典型的には、入口タンクと出口タンクとの間に連結された複数本の互いに間隔を置いて設けられた流体導管又は管と、隣り合う導管相互間に設けられた複数個の熱交換フィンとを有する空気は、例えば冷却ファン又は車両の運動により熱交換器のフィン全体にわたって当てられる。空気がフィン全体にわたって流れると、管を通って流れている流体の熱が、管の壁を通ってフィンに伝達され、そして空気中に伝えられる。   Air-cooled finned heat exchangers are very well known. Heat exchangers are used to change the temperature of various working fluids such as engine coolants such as engine lubricants, air conditioning refrigerants, and automatic transmission fluids. A heat exchanger is typically a plurality of spaced apart fluid conduits or tubes connected between an inlet tank and an outlet tank, and a plurality of adjacent conduits. The air with the heat exchange fins is applied across the fins of the heat exchanger, for example by movement of a cooling fan or vehicle. As air flows across the fins, the heat of the fluid flowing through the tubes is transferred to the fins through the tube walls and into the air.

熱交換器の設計上の主要な目的のうちの１つは、高いフィン長柱強度を達成することにある。フィンの複合厚さが大きければ大きいほど、フィンの強度がそれだけ一層高くなるということが知られている。しかしながら、フィンの複合厚さを増大させると、その結果、フィンを製造するために用いられる材料の量が多くなる。材料の量が多くなると、その結果として、追加の重量が生じ、これは望ましくない。フィンの強度を高めるために複合厚さを増大させる目的で先行技術において種々のタイプのフィン設計例が開示されている。熱交換器用のルーバ付きフィンであって、これと関連した強度が最大限に高められると共に材料使用量が最小限に抑えられたフィンを製造することが望ましい。   One of the main objectives of the heat exchanger design is to achieve high fin column strength. It is known that the greater the composite thickness of the fins, the higher the strength of the fins. However, increasing the composite thickness of the fin results in an increase in the amount of material used to manufacture the fin. Larger amounts of material result in additional weight, which is undesirable. Various types of fin design examples have been disclosed in the prior art for the purpose of increasing the composite thickness to increase fin strength. It would be desirable to produce louvered fins for heat exchangers that maximize the associated strength while minimizing material usage.

本発明に従って、熱交換器用のルーバ付きフィンであって、これと関連した強度が最大限に高められると共に材料の使用量が最小限に抑えられたフィンが得られたが、これは驚くべきことである。   In accordance with the present invention, a louvered fin for a heat exchanger has been obtained which has the maximum strength associated with it and the least amount of material used, which is surprising.

As shown in FIG. 2, the turning louver 26 includes a first surface 43, a second surface 45, a first edge 44, a second edge 46 spaced from the first edge 46, and a rib 48. Have. A rib 48 is formed between the first edge 44 and the second edge 46, and this rib extends laterally outward from the second surface 45. A single rib 48 is shown formed on the turning louver 26. However, it goes without saying that a greater or lesser number of ribs 48 may be formed in the turning louver 26 as desired. The rib 48 extends from the first end 40 of the turning louver 26 to the second end 42.

出口ルーバ２８及び後縁ルーバ２９は、第１の端部５０がベース壁１２の上方部分１４に連結されると共に第２の端部５２がベース壁１２の下方部分１６に連結されている。図２に示すように、出口ルーバ２８の各々及び後縁ルーバ２９は、第１の表面５３、第２の表面５５、第１の縁部５４、これから間隔を置いて位置した第２の縁部５６、及びリブ５８を有している。リブ５８は、第１の縁部５４と第２の縁部５６との間に形成され、このリブは、第２の表面５５から側方外方に延びている。単一のリブ５８が、各出口ルーバ２８及び後縁ルーバ２９に形成された状態で示されている。しかしながら、所望に応じてこれよりも多い数又は少ない数のリブ５８を出口ルーバ２８及び後縁ルーバ２９に形成してもよいことは言うまでもない。リブ５８は、出口ルーバ２８及び後縁ルーバ２９の第１の端部５０から第２の端部５２まで延びている。隙間５９が、隣り合うルーバ２８，２９相互間及び転回ルーバ２６と、この転回ルーバ２６に隣接して位置する出口ルーバ２８との間に形成されている。   The outlet louver 28 and the trailing edge louver 29 have a first end 50 connected to the upper portion 14 of the base wall 12 and a second end 52 connected to the lower portion 16 of the base wall 12. As shown in FIG. 2, each of the outlet louvers 28 and the trailing edge louver 29 includes a first surface 53, a second surface 55, a first edge 54, and a second edge spaced therefrom. 56 and ribs 58. A rib 58 is formed between the first edge 54 and the second edge 56, and this rib extends laterally outward from the second surface 55. A single rib 58 is shown formed on each outlet louver 28 and trailing edge louver 29. However, it will be appreciated that a greater or lesser number of ribs 58 may be formed in the outlet louver 28 and trailing edge louver 29 as desired. The rib 58 extends from the first end 50 to the second end 52 of the outlet louver 28 and the trailing edge louver 29. A gap 59 is formed between the adjacent louvers 28 and 29 and between the turning louver 26 and the outlet louver 28 located adjacent to the turning louver 26.

当該技術分野において知られているように、空気が、隣り合う入口ルーバ２４相互間の隙間３９を通って流れるようになる。流れ管（図示せず）中を流れる流体（図示せず）から奪われた熱は、熱交換器フィン１０及び入口ルーバ２４を介して空気に伝達される。次に、空気は、転回ルーバ２６のところで方向を変えるようになる。空気は、隣り合う出口ルーバ２８相互間の隙間５９を通って流れ、ここで追加の熱が出口ルーバ２８から空気に伝達される。   As is known in the art, air will flow through a gap 39 between adjacent inlet louvers 24. Heat deprived from a fluid (not shown) flowing through a flow tube (not shown) is transferred to the air through the heat exchanger fins 10 and the inlet louver 24. The air then changes direction at the turning louver 26. The air flows through a gap 59 between adjacent outlet louvers 28 where additional heat is transferred from the outlet louvers 28 to the air.

ルーバ２４，２６，２８の複合厚さは、リブ３８，４８，５８がルーバ２４，２６，２８に形成された結果として増大している。ルーバ２４，２６，２８の複合厚さの増大の結果として、フィン１０の強度が増大する。図１及び図２に示す実施形態の場合、約１８％の強度の増大が測定された。   The combined thickness of the louvers 24, 26, 28 increases as a result of the ribs 38, 48, 58 being formed in the louvers 24, 26, 28. As a result of the increased composite thickness of the louvers 24, 26, 28, the strength of the fin 10 increases. For the embodiment shown in FIGS. 1 and 2, an increase in intensity of about 18% was measured.

フィン１０の強度の増大により、フィン１０を作るのに薄手の平らな素材を用いることができる。したがって、強度が先行技術のフィン構造と実質的に同一のフィン１０を少ない材料で作ることができる。かくして、フィン１０の総重量は、最小限に抑えられる。リブ３８，４８，５８が形成されたルーバ２４，２６，２８を有するフィン１０を先行技術のフィン構造よりも最高２０％材料を少なくした状態で作ることができるということが判明した。   Due to the increased strength of the fin 10, a thin flat material can be used to make the fin 10. Accordingly, the fin 10 having substantially the same strength as that of the prior art fin structure can be made with less material. Thus, the total weight of the fin 10 is kept to a minimum. It has been found that fins 10 having louvers 24, 26, 28 with ribs 38, 48, 58 can be made with up to 20% less material than prior art fin structures.

次に、図１及び図２に記載された熱交換器フィン１０の形成方法を説明する。実質的に平らな材料、例えばアルミニウムのシート１１０を用意する。図７に示すように、材料シート１１０を高さ及び真直度（ストレートネス）調整のために保持ロール１１１に送り込み、次に１組のリブ成形ロール１１２に送り込む。リブ成形ロール１１２のうちの第１のものは、複数の互いに間隔を置いた環状突起（図示せず）を有している。リブ成形ロール１１２のうちの第２のものは、複数の互いに間隔を置いた環状チャネル又は凹みを有している。リブ成形ロール１１２の突起及び凹みは、材料シート１１０に複数個の連続したリブ３８，４８，５８を形成するよう協働する。オプションとして、次に、材料シート１１０を図８に示すように第２の保持ロール１１１に送り込むのがよい。しかる後、シート１１０を１組の波形フィン成形ロール１１４に送り込む。波形フィン成形ロール１１４に設けられたカッタ（図示せず）が、複数の列を形成するようシート１１０を切断する。各列は、前縁ルーバ２３、複数の入口ルーバ２４、転回ルーバ２６、複数の出口ルーバ２８、及び後縁ルーバ２９を含む。波形フィン成形ロール１１４は、シート１１０を同時に交互に曲げて波形部を形成し、シート１１０に波状の形を与える。波形フィン成形ロール１１４も又、ルーバ２３，２４，２６，２８，２９の隣り合う列相互間でシート１１０を平らにするよう協働する。かくして、シート１１０の頂部１４及び底部１６に形成されたリブ３８，４８，５８は、除去される。シート１１０を密度ステーション１１６に送り込み、ここでシート１１０に対する更なる調節を所望に応じて達成するのがよい。シート１１０をカットオフステーション１１８に送り込み、ここでシート１１０を所望長さ通りに切断する。   Next, a method for forming the heat exchanger fin 10 described in FIGS. 1 and 2 will be described. A substantially flat material such as aluminum sheet 110 is provided. As shown in FIG. 7, the material sheet 110 is fed to the holding roll 111 for height and straightness adjustment, and then fed to a set of rib forming rolls 112. A first one of the rib forming rolls 112 has a plurality of spaced annular protrusions (not shown). A second one of the rib forming rolls 112 has a plurality of spaced apart annular channels or recesses. The protrusions and recesses of the rib forming roll 112 cooperate to form a plurality of continuous ribs 38, 48, 58 in the material sheet 110. Optionally, the material sheet 110 can then be fed into the second holding roll 111 as shown in FIG. Thereafter, the sheet 110 is fed into a set of corrugated fin forming rolls 114. A cutter (not shown) provided on the corrugated fin forming roll 114 cuts the sheet 110 so as to form a plurality of rows. Each row includes a leading edge louver 23, a plurality of inlet louvers 24, a turning louver 26, a plurality of outlet louvers 28, and a trailing edge louver 29. The corrugated fin forming roll 114 forms the corrugated portion by alternately bending the sheets 110 at the same time, and gives the sheet 110 a wavy shape. The corrugated fin forming roll 114 also cooperates to flatten the sheet 110 between adjacent rows of louvers 23, 24, 26, 28, 29. Thus, the ribs 38, 48, 58 formed on the top 14 and bottom 16 of the sheet 110 are removed. Sheet 110 may be fed to density station 116 where further adjustments to sheet 110 may be achieved as desired. The sheet 110 is fed to a cut-off station 118 where the sheet 110 is cut to the desired length.

上述した図５に記載されているフィン１０″を形成するため、上述のプロセスからルーバ２３″，２４″，２６″，２８″，２９″の隣り合う列相互間でシート１１０を平らにするステップを無くす。この方法により作られたリブ３８″，４８″，５８″は、ルーバ２４″，２６″，２８″の第１の端部３０，４０，５０及び第２の端部３２，４２，５２のところで終端しないで、フィン１０の第１の端部１５からフィン１０の第２の端部１７まで連続して延びる。   Flattening sheets 110 between adjacent rows of louvers 23 ", 24", 26 ", 28", 29 "from the above process to form the fin 10" described in FIG. 5 above. Is lost. The ribs 38 ", 48", 58 "made by this method are at the first ends 30, 40, 50 and second ends 32, 42, 52 of the louvers 24", 26 ", 28".
