Description

本発明は、フィンチューブ型熱交換器、特に、気流中に配置された伝熱フィンと、伝熱フィンに挿入されており気流の流れ方向に略直交する方向に配置された複数の伝熱管とを備えたフィンチューブ型熱交換器に関する。   The present invention relates to a finned tube heat exchanger, in particular, heat transfer fins arranged in an air flow, and a plurality of heat transfer tubes inserted in the heat transfer fins and arranged in a direction substantially perpendicular to the flow direction of the air flow, It is related with the fin tube type heat exchanger provided with.

従来より、空気調和装置等において、空気流中に配置された伝熱フィンと、伝熱フィンに挿入されており空気流の流れ方向に略直交する向きに配置された複数の伝熱管とを備えたフィンチューブ型熱交換器（すなわち、クロスフィンアンドチューブ型熱交換器）がよく用いられている。
このようなフィンチューブ型熱交換器では、伝熱フィンにおける伝熱管の空気流の流れ方向下流側の部分に形成される死水域の低減、及び、伝熱フィンにおける境界層の更新を目的とした伝熱促進手法として、伝熱フィン面の伝熱管の両側の位置に、空気流の流れ方向上流側に向かって拡開する案内フィンを、切り起こしにより形成する手法が採用されることがある（特許文献１参照）。
特開昭６１−１１０８８９号公報 Conventionally, in an air conditioner or the like, a heat transfer fin disposed in an air flow, and a plurality of heat transfer tubes inserted in the heat transfer fin and disposed in a direction substantially orthogonal to the flow direction of the air flow are provided. Fin tube type heat exchangers (ie, cross fin and tube type heat exchangers) are often used.
In such a finned tube heat exchanger, the purpose is to reduce the dead water area formed in the downstream side of the airflow direction of the heat transfer tube in the heat transfer fin, and to update the boundary layer in the heat transfer fin. As a heat transfer promotion method, a method may be employed in which guide fins that are widened toward the upstream side in the air flow direction are formed by cutting and raising at positions on both sides of the heat transfer tube on the heat transfer fin surface ( Patent Document 1).
JP-A-61-110889

しかし、上述のような案内フィンが採用されたフィンチューブ型熱交換器を、空気調和装置等に代表されるような空気を熱源とする冷媒等の熱媒体の蒸発器として使用する場合には、空気と熱媒体との熱交換により発生したドレン水が案内フィンに滞留して通風抵抗を増大させるという問題が生じてしまう。また、上述のような案内フィンが採用されたフィンチューブ型熱交換器を、空気調和装置の室外ユニットを構成する室外熱交換器として使用する場合には、伝熱フィン面に発生した霜を除霜運転により除去することがあるが、この際の排水性を低下させるという問題が生じてしまう。   However, when the fin tube type heat exchanger employing the above-described guide fins is used as an evaporator for a heat medium such as a refrigerant using air as a heat source as represented by an air conditioner or the like, There arises a problem that drain water generated by heat exchange between the air and the heat medium stays in the guide fins and increases the ventilation resistance. In addition, when using a fin-tube heat exchanger employing guide fins as described above as an outdoor heat exchanger that constitutes an outdoor unit of an air conditioner, frost generated on the heat transfer fin surface is removed. Although it may be removed by a frost operation, there arises a problem of reducing the drainage at this time.

本発明の課題は、フィンチューブ型熱交換器において、案内フィンによる伝熱促進効果と排水性とを両立させることにある。   An object of the present invention is to achieve both the heat transfer acceleration effect and drainage performance by the guide fin in the fin tube heat exchanger.

第１の発明にかかるフィンチューブ型熱交換器は、気流中に配置された伝熱フィンと、伝熱フィンに挿入されており気流の流れ方向に略直交する方向に配置された複数の伝熱管とを備えている。伝熱フィンには、伝熱管の両側において、気流の流れ方向上流側から下流側に向かって真っ直ぐに並ぶ複数の案内フィンが、切り起こしにより、伝熱フィン面に形成されている。複数の案内フィンを仮想的に結ぶ直線は、伝熱管近傍の気流を、伝熱管の気流の流れ方向後側に案内するように、気流の流れ方向に対して傾斜している。   A finned tube heat exchanger according to a first aspect of the present invention includes a heat transfer fin disposed in an air flow and a plurality of heat transfer tubes inserted in the heat transfer fin and disposed in a direction substantially orthogonal to the flow direction of the air flow. And. In the heat transfer fins, on both sides of the heat transfer tube, a plurality of guide fins arranged straight from the upstream side to the downstream side in the airflow direction are formed on the heat transfer fin surface by cutting and raising. The straight line that virtually connects the plurality of guide fins is inclined with respect to the airflow direction so as to guide the airflow in the vicinity of the heat transfer tube to the rear side in the airflow direction of the heat transfer tube.

このフィンチューブ型熱交換器では、案内フィンが気流の流れ方向上流側から下流側に向かって複数に分割されており、かつ、複数の案内フィンが伝熱管近傍の気流を伝熱管の気流の流れ方向後側に案内するように気流の流れ方向に対して傾斜しているため、主として、複数の案内フィンのうち伝熱フィンの気流の流れ方向前側に配置された案内フィンによって境界層を更新する効果を確実に得ること、及び、伝熱フィンの気流の流れ方向後側に配置された案内フィンによって伝熱管の気流の流れ方向後側の部分に形成される死水域を低減する効果を得ることができるとともに、伝熱フィン面に発生したドレン水を案内フィン間の隙間から排出されやすくすることができる。これにより、伝熱フィン面に発生するドレン水の影響を受けることなく、案内フィンによる伝熱促進効果を得ることができるようになる。   In this fin tube type heat exchanger, the guide fins are divided into a plurality of parts from the upstream side to the downstream side in the airflow direction, and the plurality of guide fins convert the airflow in the vicinity of the heat transfer tube to the flow of the airflow in the heat transfer tube. Since it is inclined with respect to the flow direction of the air flow so as to be guided rearward in the direction, the boundary layer is mainly updated by the guide fins arranged on the front side in the flow direction of the air flow of the heat transfer fins among the plurality of guide fins. Obtaining the effect reliably and obtaining the effect of reducing the dead water area formed in the rear portion of the heat transfer pipe in the air flow direction by the guide fins arranged on the rear side in the air flow direction of the heat transfer fin The drain water generated on the heat transfer fin surface can be easily discharged from the gap between the guide fins. Thereby, the heat transfer promotion effect by the guide fin can be obtained without being affected by the drain water generated on the heat transfer fin surface.

しかも、複数の案内フィンが気流の流れ方向上流側から下流側に向かって真っ直ぐに並ぶことによって、複数の案内フィンのうち伝熱フィンの気流の流れ方向後側に配置された案内フィンが気流の流れ方向前側に配置された案内フィンと同じ傾斜を有することになるため、伝熱管の気流の流れ方向後側の部分に形成される死水域を低減するだけでなく、案内フィンの背後に新たな死水域が形成されるのを防ぐことができる。   Moreover, by arranging the plurality of guide fins straight from the upstream side to the downstream side in the airflow direction, the guide fins arranged on the rear side in the airflow direction of the heat transfer fins out of the plurality of guide fins Since it has the same inclination as the guide fin arranged on the front side in the flow direction, not only the dead water area formed at the rear side in the flow direction of the heat flow of the heat transfer tube is reduced, but a new one is provided behind the guide fin. It is possible to prevent the formation of dead water areas.

以上のように、本発明にかかるフィンチューブ型熱交換器では、伝熱フィン面に発生するドレン水の影響を受けることなく、案内フィンによる伝熱促進効果を得ることができるとともに、案内フィンの背後に新たな死水域が形成されるのを防ぐことができるため、案内フィンによる伝熱促進効果と排水性とを両立させることができる。   As described above, in the finned tube heat exchanger according to the present invention, the heat transfer promotion effect by the guide fin can be obtained without being affected by the drain water generated on the heat transfer fin surface, and Since it is possible to prevent a new dead water area from being formed behind, it is possible to achieve both the heat transfer promotion effect by the guide fins and the drainage.

このフィンチューブ型熱交換器では、各案内フィンの形状を気流の流れ方向下流側に向かって高さが漸増した形状にすることによって、各案内フィンの背後に縦渦を生じさせることができるため、案内フィンによる伝熱促進効果をさらに高めることができる。 The finned tube heat exchanger according to the second invention is the finned tube heat exchanger according to the first invention, wherein the height of each guide fin gradually increases toward the downstream side in the airflow direction.
In this fin tube type heat exchanger, since the shape of each guide fin is gradually increased in height toward the downstream side in the air flow direction, a vertical vortex can be generated behind each guide fin. The heat transfer promoting effect by the guide fins can be further enhanced.

第３の発明にかかるフィンチューブ型熱交換器は、第１又は第２の発明にかかるフィンチューブ型熱交換器において、伝熱フィンには、直線上において互いに隣り合う案内フィン間に滞留する水を、下方に流下させるための排水促進部が形成されている。

Two guide fins 21a and 21b and guide fins 21c and 21d are formed on the heat transfer fin 2 surface by cutting and raising. The straight lines L 1 and L 2 that virtually connect the guide fins 21a and 21b or the guide fins 21c and 21d are arranged to guide the airflow in the vicinity of the heat transfer tube 3 to the rear side in the flow direction of the airflow of the heat transfer tube 3. It is inclined with respect to the flow direction. Here, the angles of attack α 1 and α 2 with respect to the flow direction of the air flow of the straight lines L 1 and L 2 are set to be within a range of 10 ° to 30 °.

また、各案内フィン２１ａ〜２１ｄは、気流の流れ方向下流側に向かって高さが漸増するように形成されている。本実施形態において、各案内フィン２１ａ〜２１ｄは、略台形状又は略三角形状であり（図３参照、図３は、案内フィン２１ｃ、２１ｄを示す図であるが、案内フィン２１ａ、２１ｂについても同様の形状を有する）、その最大高さｈがカラー部２３の高さＨよりも低くなるように形成されている。また、案内フィン２１ａ〜２１ｄが切り起こされる際に伝熱フィン２に形成されるスリット孔２２ａ〜２２ｄは、案内フィン２１ａ〜２１ｄを挟んで伝熱管３よりも遠い側に配置されている。   Moreover, each guide fin 21a-21d is formed so that height may increase gradually toward the flow direction downstream.

Since the air flow is inclined with respect to the air flow direction so as to guide the air flow in the heat transfer tube 3 to the rear side in the air flow direction, the air flow of the heat transfer fin 2 is mainly forward of the guide fins 21a to 21d. The effect of renewing the boundary layer by the arranged guide fins 21a and 21c is surely obtained, and the guide fins 21b and 2 arranged on the rear side in the air flow direction of the heat transfer fins 2 1d can obtain the effect of reducing the dead water area formed in the rear portion of the heat transfer tube 3 in the direction of the air flow, and drain water generated on the surface of the heat transfer fin 2 between the guide fins 21a and 21b and the guide. It can be easily discharged from the gap between the fins 21c and 21d. Thereby, the heat transfer promotion effect by the guide fins 21a to 21d can be obtained without being affected by the drain water generated on the surface of the heat transfer fin 2.

しかも、案内フィン２１ａ、２１ｂ及び案内フィン２１ｃ、２１ｄが気流の流れ方向上流側から下流側に向かって直線Ｌ1及び直線Ｌ2上を真っ直ぐに並ぶことによって、案内フィン２１ａ〜２１ｄのうち伝熱フィン２の気流の流れ方向後側に配置された案内フィン２１ｂ、２１ｄが気流の流れ方向前側に配置された案内フィン２１ａ、２１ｃと同じ傾斜を有することになるため、伝熱管３の気流の流れ方向後側の部分に形成される死水域を低減するだけでなく、案内フィン２１ｂ、２１ｄの背後に新たな死水域が形成されるのを防ぐことができる。 Moreover, the guide fins 21a, 21b and the guide pin 21c, by 21d are arranged straight over the lines L 1 and the straight line L 2 toward the downstream side from the flow direction upstream side of the air flow, of heat transfer of the guide fins 21a~21d Since the guide fins 21b, 21d arranged on the rear side in the airflow direction of the fin 2 have the same inclination as the guide fins 21a, 21c arranged on the front side in the airflow direction, the airflow of the heat transfer tube 3 In addition to reducing the dead water area formed in the rear portion of the direction, it is possible to prevent a new dead water area from being formed behind the guide fins 21b and 21d.

以上のように、本実施形態のフィンチューブ型熱交換器１では、伝熱フィン２面に発生するドレン水の影響を受けることなく、案内フィン２１ａ〜２１ｄによる伝熱促進効果を得ることができるとともに、案内フィン２１ｂ、２１ｄの背後に新たな死水域が形成されるのを防ぐことができるため、案内フィンによる伝熱促進効果と排水性とを両立させることができる。
また、このフィンチューブ型熱交換器１では、各案内フィン２１ａ〜２１ｄの形状を気流の流れ方向下流側に向かって高さが漸増した形状にすることによって、各案内フィン２１ａ〜２１ｄの背後に縦渦を生じさせることができるため、各案内フィン２１ａ〜２１ｄによる伝熱促進効果をさらに高めることができる。 As described above, in the finned tube heat exchanger 1 of the present embodiment, the heat transfer promotion effect by the guide fins 21a to 21d can be obtained without being affected by the drain water generated on the surface of the heat transfer fin 2. In addition, since it is possible to prevent a new dead water area from being formed behind the guide fins 21b and 21d, it is possible to achieve both the heat transfer promotion effect by the guide fins and the drainage.
Moreover, in this fin tube type heat exchanger 1, the shape of each guide fin 21a-21d is made into the shape which height increased gradually toward the downstream of the flow direction of airflow, and it is behind each guide fin 21a-21d. Since the vertical vortex can be generated, the heat transfer promotion effect by the guide fins 21a to 21d can be further enhanced.

FIG. 8 is a cross-sectional view taken along the line AA of FIG. 9 is a cross-sectional view taken along the line BB in FIG.
(1) Configuration of Fin Tube Type Heat Exchanger The basic configuration of the fin tube type heat exchanger 101 is the fin tube type heat exchange of the first embodiment except for guide fins 121a to 121f of the heat transfer fin 102 described later. The configuration of the vessel 1 is the same. For this reason, about the basic composition of the fin tube type heat exchanger 101, description about the heat transfer fin 102 will be omitted by replacing the reference numerals from the 10th to the 100th.

次に、本実施形態のフィンチューブ型熱交換器１０１に用いられている伝熱フィン１０２の詳細形状について説明する。
伝熱フィン１０２には、各伝熱管３の両側（すなわち、各伝熱管３の下側及び上側）において、気流の流れ方向上流側から下流側に向かって真っ直ぐに並ぶ複数（本実施形態では、３つ）の案内フィン１２１ａ、１２１ｂ、１２１ｃ及び案内フィン１２１ｄ、１２１ｅ、１２１ｆが、切り起こしにより、伝熱フィン１０２面に形成されている。この案内フィン１２１ａ、１２１ｂ、１２１ｃ又は案内フィン１２１ｄ、１２１ｅ、１２１ｆを仮想的に結ぶ直線Ｌ1、Ｌ2は、伝熱管３近傍の気流を、伝熱管３の気流の流れ方向後側に案内するように、気流の流れ方向に対して傾斜している。ここで、直線Ｌ1、Ｌ2の気流の流れ方向に対する迎え角α1、α2は、１０°〜３０°の範囲内になるように設定されている。 Next, the detailed shape of the heat transfer fin 102 used in the finned tube heat exchanger 101 of the present embodiment will be described.

Three) guide fins 121a, 121b, 121c and guide fins 121d, 121e, 121f are formed on the surface of the heat transfer fin 102 by cutting and raising. The straight lines L 1 and L 2 that virtually connect the guide fins 121a, 121b, 121c or the guide fins 121d, 121e, 121f guide the airflow in the vicinity of the heat transfer tube 3 to the rear side in the flow direction of the airflow of the heat transfer tube 3. As shown in FIG. Here, the angles of attack α 1 and α 2 with respect to the flow direction of the air flow of the straight lines L 1 and L 2 are set to be within a range of 10 ° to 30 °.

また、各案内フィン１２１ａ〜１２１ｆは、気流の流れ方向下流側に向かって高さが漸増するように形成されている。本実施形態において、各案内フィン１２１ａ〜１２１ｆは、略台形状又は略三角形状であり（図９参照、図９は、案内フィン１２１ｄ、１２１ｅ、１２１ｆを示す図であるが、案内フィン１２１ａ、１２１ｂ、１２１ｃについても同様の形状を有する）、その最大高さｈがカラー部１２３の高さＨよりも低くなるように形成されている。また、案内フィン１２１ａ〜１２１ｄが切り起こされる際に伝熱フィン１０２に形成されるスリット孔１２２ａ〜１２２ｆは、案内フィン１２１ａ〜１２１ｆを挟んで伝熱管３よりも遠い側に配置されている。   Moreover, each guide fin 121a-121f is formed so that height may increase gradually toward the flow direction downstream. In the present embodiment, each of the guide fins 121a to 121f has a substantially trapezoidal shape or a substantially triangular shape (see FIG. 9, FIG. 9 is a view showing the guide fins 121d, 121e, and 121f, but the guide fins 121a and 121b). , 121 c have the same shape), and the maximum height h is lower than the height H of the collar portion 123. In addition, slit holes 122a to 122f formed in the heat transfer fin 102 when the guide fins 121a to 121d are cut and raised are disposed on the side farther than the heat transfer tube 3 with the guide fins 121a to 121f interposed therebetween.

Slits 132, 133, 136, and 137 (see FIG. 10) as drainage promotion portions that allow water staying between the guide fins 121b and 121c, between the guide fins 121d and 121e, and between the guide fins 121e and 121f to flow downward. Notches 142, 143, 144, 145 (see FIG. 11) or water guiding ribs 152, 153 ( 12 see) may be formed. Here, FIGS. 10 to 12 are views showing a portion C of FIG. 7 when various drainage promotion portions are formed on the heat transfer fins 102.

尚、スリット、切り欠き及び導水リブの形状等は、第１実施形態の変形例にかかるスリット３２、３５、切り欠き４２、４３又は導水リブ５２と同様であるため説明を省略する。また、このフィンチューブ型熱交換器１０１においても、第１実施形態の変形例にかかるフィンチューブ型熱交換器１と同様に、伝熱フィン１０２面に発生したドレン水を案内フィン１２１ａ、１２１ｂ間、案内フィン１２１ｂ、１２１ｃ間、案内フィン１２１ｄ、１２１ｅ間、及び案内フィン１２１ｅ、１２１ｆ間以外の部分にも、スリット１３１、１３４、１３５、１３８、切り欠き１４１、１４６又は導水リブ１５１、１５４を形成してもよい。   In addition, since the shape of a slit, a notch, and a water guide rib is the same as that of the slits 32 and 35, the notches 42, 43, or the water guide rib 52 concerning the modification of 1st Embodiment, description is abbreviate | omitted. Also in the fin tube type heat exchanger 101, the drain water generated on the surface of the heat transfer fin 102 is transferred between the guide fins 121a and 121b in the same manner as the fin tube type heat exchanger 1 according to the modification of the first embodiment. , Slits 131, 134, 135, 138, notches 141, 146 or water guide ribs 151, 154 are formed in portions other than between the guide fins 121 b, 121 c, between the guide fins 121 d, 121 e, and between the guide fins 121 e, 121 f.
