It should be apparent that the described embodiments are merely some, but not all embodiments of the present application. The following description of at least one exemplary embodiment is merely illustrative and in no way restrictive of the present application and its application or use. All other embodiments obtained by those skilled in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

図面に示されるように、本出願の実施例は、順に接続された第１のパイプセグメント１１、湾曲パイプセグメント１２及び第２のパイプセグメント１３を含む扁平管１０であって、扁平管１０は複数であり、複数の扁平管１０は並んで設けられ、隣接する２つの湾曲パイプセグメント１２間にギャップを有する扁平管１０と、延在方向が扁平管１０の延在方向に垂直であり、複数の湾曲パイプセグメント１２うちの少なくとも一部の湾曲パイプセグメント１２に接続され、複数の湾曲パイプセグメント１２におけるギャップを遮蔽するフィン２０と、を含む熱交換器を提供する。 As shown in the drawings, an embodiment of the present application is a flat pipe 10 comprising a first pipe segment 11, a curved pipe segment 12 and a second pipe segment 13 connected in sequence, wherein the flat pipe 10 comprises a plurality of , the plurality of flat tubes 10 are provided side by side, the flat tubes 10 having a gap between two adjacent curved pipe segments 12, the extending direction perpendicular to the extending direction of the flat tubes 10, and the plurality of flat tubes 10 fins (20) connected to at least some of the curved pipe segments (12) and shielding gaps in the plurality of curved pipe segments (12).

この態様を採用すると、複数の湾曲パイプセグメント１２の位置にフィン２０が設けられているため、複数の湾曲パイプセグメント１２が位置する領域において、フィン２０によって複数の湾曲パイプセグメント１２間の複数のギャップを遮蔽することで、ギャップ間で漏風する状況を回避して、熱交換器の熱交換性能を向上させることができ、そしてフィン２０を設けることで、湾曲パイプセグメント１２を保護して、湾曲パイプセグメント１２の腐食又は損傷を減少させて、熱交換器の耐用性を向上させることができる。そしてフィン２０は、延在方向が扁平管１０の延在方向に垂直で、フィン２０が複数の湾曲パイプセグメント１２間の複数のギャップを遮蔽することが容易になり、遮風効果を向上させる。 By adopting this aspect, since the fins 20 are provided at the positions of the plurality of curved pipe segments 12, the fins 20 create gaps between the plurality of curved pipe segments 12 in the regions where the plurality of curved pipe segments 12 are located. can improve the heat exchange performance of the heat exchanger by avoiding the situation of air leakage between the gaps, and the fins 20 are provided to protect the curved pipe segment 12 to prevent the curved pipe Corrosion or damage to the segments 12 can be reduced to improve the durability of the heat exchanger. The extending direction of the fins 20 is perpendicular to the extending direction of the flat pipe 10, so that the fins 20 can easily shield the gaps between the curved pipe segments 12, improving the wind shielding effect.

ここでフィン２０は、延性が良好な金属材料により製作されてもよく、湾曲パイプセグメント１２が屈曲する過程でフィン２０が湾曲パイプセグメント１２に伴って変形しやすく、これにより、湾曲パイプセグメント１２が屈曲した後、フィン２０は依然として複数の湾曲パイプセグメント１２間の複数のギャップを遮蔽している。 Here, the fins 20 may be made of a metal material with good ductility, and the fins 20 are easily deformed along with the curved pipe segments 12 in the course of bending of the curved pipe segments 12, thereby allowing the curved pipe segments 12 to bend. After bending, the fins 20 still block gaps between the curved pipe segments 12 .

図３及び図４に示されるように、フィン２０は、バッフル２１、第１の端板２２及び第２の端板２３を含み、第１の端板２２及び第２の端板２３は、それぞれバッフル２１の両端に設けられ、ここでバッフル２１は、複数の湾曲パイプセグメント１２の一方の側を遮蔽し、第１の端板２２及び第２の端板２３と、複数の湾曲パイプセグメント１２のうちの２つの湾曲パイプセグメント１２とは、一対一に対応して接続される。第１の端板２２、第２の端板２３がそれぞれ２つの湾曲パイプセグメント１２に接続されることで、フィン２０に対する固定を実現することができる。ギャップでの漏風を回避するように、バッフル２１によって、複数の湾曲パイプセグメント１２間の複数のギャップを遮蔽することができる。そして上記の設定を採用すると、構造が簡単で製造が容易である。 As shown in FIGS. 3 and 4, the fin 20 includes a baffle 21, a first end plate 22 and a second end plate 23, the first end plate 22 and the second end plate 23 respectively provided at both ends of the baffle 21 , where the baffle 21 shields one side of the plurality of curved pipe segments 12 , the first end plate 22 and the second end plate 23 , and the plurality of curved pipe segments 12 . Two of the curved pipe segments 12 are connected in a one-to-one correspondence. A first end plate 22 and a second end plate 23 are connected to the two curved pipe segments 12 respectively, so that fixing to the fin 20 can be achieved. The gaps between the curved pipe segments 12 can be shielded by the baffles 21 so as to avoid wind leakage at the gaps. And if the above setting is adopted, the structure is simple and the manufacture is easy.

更に、フィン２０は複数設けられてもよく、複数のフィン２０のうちの少なくとも１つのフィン２０のバッフル２１は、複数の湾曲パイプセグメント１２の一方の側を遮蔽し、複数のフィン２０のうちの他のフィン２０のバッフル２１は、複数の湾曲パイプセグメント１２の他方の側を遮蔽する。これにより、複数の湾曲パイプセグメント１２の両側にはいずれもフィン２０が設けられており、ギャップに対する遮蔽効果を向上させることができ、且つ湾曲パイプセグメント１２をより良好に保護することができる。ここで複数の湾曲パイプセグメント１２の両側は、湾曲パイプセグメント１２が屈曲した後の複数の湾曲パイプセグメント１２の外側及び内側であると理解することができる。 Further, a plurality of fins 20 may be provided, and the baffle 21 of at least one fin 20 among the plurality of fins 20 shields one side of the plurality of curved pipe segments 12, and the baffle 21 of the plurality of fins 20 A baffle 21 of another fin 20 shields the other side of the plurality of curved pipe segments 12 . As a result, the fins 20 are provided on both sides of the plurality of curved pipe segments 12 to improve the effect of shielding gaps and to better protect the curved pipe segments 12 . Here, both sides of the plurality of curved pipe segments 12 can be understood to be the outside and the inside of the plurality of curved pipe segments 12 after the curved pipe segments 12 are bent.

図５から図９に示されるように、フィン２０は複数の凹溝２４を有し、複数の凹溝２４はフィン２０の長さ方向に間隔をおいて設けられ、各湾曲パイプセグメント１２の少なくとも一部の構造はいずれも複数の凹溝２４のうちの１つの凹溝２４内に位置している。これにより、フィン２０と複数の湾曲パイプセグメント１２との接続強度が高くなり、且つフィン２０が湾曲パイプセグメント１２に伴って屈曲する過程で変形しやすく、変形後もギャップを良好に遮蔽することができる。ここで、フィン２０は波状構造になるように設けられてもよい。 As shown in FIGS. 5-9, the fin 20 has a plurality of grooves 24 spaced along the length of the fin 20 to provide at least one curved pipe segment 12 for each curved pipe segment 12 . All of the partial structures are located within one recessed groove 24 of the plurality of recessed grooves 24 . As a result, the connection strength between the fins 20 and the plurality of curved pipe segments 12 is increased, and the fins 20 are easily deformed in the process of bending along with the curved pipe segments 12, and the gaps can be satisfactorily shielded even after deformation. can. Here, the fins 20 may be provided in a wave-like structure.

ここで、凹溝２４の数量は湾曲パイプセグメント１２の数量と等しくなるように設けられ、複数の湾曲パイプセグメント１２と、複数の凹溝２４は、一対一に対応して設けられていてもよい。 Here, the number of grooves 24 is equal to the number of curved pipe segments 12, and the plurality of curved pipe segments 12 and the plurality of grooves 24 may be provided in one-to-one correspondence. .

あるいは、凹溝２４の数量は湾曲パイプセグメント１２の数量よりも多くなるように設けられ、隣接する２つの湾曲パイプセグメント１２間には湾曲パイプセグメント１２に係合されていない凹溝２４を少なくとも１つ有してもよい。これにより、フィン２０が湾曲パイプセグメント１２に伴って屈曲する過程でより変形しやすい。 Alternatively, the number of recessed grooves 24 is greater than the number of curved pipe segments 12 , and at least one recessed groove 24 not engaged with the curved pipe segment 12 is provided between two adjacent curved pipe segments 12 . may have one. This makes it easier for the fins 20 to deform in the process of bending along with the curved pipe segments 12 .

上記の実施例において、フィン２０の、隣接する２つの湾曲パイプセグメント１２間に位置する部分は、弧形構造、平板構造又はＶ型構造になるように設けられてもよい。 In the above embodiments, the portion of the fins 20 located between two adjacent curved pipe segments 12 may be provided in an arc-shaped configuration, a flat plate configuration or a V-shaped configuration.

図１０に示されるように、別の実施例において、フィン２０は順に接続された折板２５を複数含み、隣接する２つの折板２５はＶ型構造をなして設けられ、隣接する２つの折板２５間には湾曲パイプセグメント１２が１つ設けられている。これにより、フィン２０は複数の湾曲パイプセグメント１２における複数のギャップをいずれも遮蔽し、且つフィン２０が湾曲パイプセグメント１２に伴って屈曲した後も湾曲パイプセグメント１２から離脱することなく、接続効果が良好である。 As shown in FIG. 10, in another embodiment, the fin 20 includes a plurality of folded plates 25 connected in series, two adjacent folded plates 25 are provided in a V-shaped configuration, and two adjacent folded plates 25 are provided. A curved pipe segment 12 is provided between the plates 25 . As a result, the fins 20 block all the gaps in the curved pipe segments 12, and the connecting effect is achieved without separating from the curved pipe segments 12 even after the fins 20 are bent along with the curved pipe segments 12. Good.

上記の実施例において、フィン２０はアルミニウム箔により製作されている。アルミニウム箔材料は、熱伝導性が良好で変形しやすいため、湾曲パイプセグメント１２が屈曲する過程で湾曲パイプセグメント１２に伴って変形しやすく、ギャップに対する遮蔽が維持されて、熱交換及び保護効果を向上させる。 In the above example, the fins 20 are made of aluminum foil. Since the aluminum foil material has good thermal conductivity and is easy to deform, it is easy to deform with the curved pipe segment 12 in the process of bending the curved pipe segment 12, and the shielding of the gap is maintained to improve the heat exchange and protection effect. Improve.

選択的に、フィン２０と湾曲パイプセグメント１２とは溶接され、これにより接続強度が高くなる。アルミニウム箔は２層又は複数層が複合されてなり、ここで一方の層は融点が高く他方の層は融点が低く、あるいは、表層は融点が低く中間層は融点が高い。溶接時、融点の低い一方の層を湾曲パイプセグメント１２に係合させる。 Alternatively, the fins 20 and the curved pipe segments 12 are welded to increase the strength of the connection. The aluminum foil is a composite of two or more layers, where one layer has a high melting point and the other layer has a low melting point, or the surface layer has a low melting point and the intermediate layer has a high melting point. During welding, one layer with the lower melting point is engaged with the curved pipe segment 12 .

上記の実施例において、フィン２０の電位は湾曲パイプセグメント１２の電位よりも低い。これにより、熱交換器を用いる過程で腐食が発生した場合にまず電位が比較的低いフィン２０が腐食し、その後湾曲パイプセグメント１２が腐食するので、フィン２０によって湾曲パイプセグメント１２を保護することで、熱交換器の耐用性を向上させる。 In the above example, the potential of the fins 20 is lower than the potential of the curved pipe segment 12 . As a result, when corrosion occurs in the process of using the heat exchanger, the fins 20 with a relatively low electric potential corrode first, and then the curved pipe segments 12 corrode. , to improve the durability of the heat exchanger.

選択的に、熱交換器は、隣接する第１のパイプセグメント１１間並びに隣接する第２のパイプセグメント１３間に設けられたメインフィンを更に含む。メインフィンを設けることで、熱交換面積及び熱交換効果を向上させることができ、且つ扁平管１０を保護することができる。具体的には、メインフィンが、第１のパイプセグメント１１及び第２のパイプセグメント１３の延在方向に延在する。 Optionally, the heat exchanger further comprises main fins provided between adjacent first pipe segments 11 and between adjacent second pipe segments 13 . By providing the main fins, the heat exchange area and heat exchange effect can be improved, and the flat tubes 10 can be protected. Specifically, the main fin extends in the extending direction of the first pipe segment 11 and the second pipe segment 13 .

上記の実施例において、熱交換器は２つの集流管３０を更に含み、ここで各第１のパイプセグメント１１はいずれも一方の集流管３０に接続され、各第２のパイプセグメント１３はいずれも他方の集流管３０に接続される。フィン２０の延在方向は集流管３０の長さ方向に平行である。 In the above embodiment, the heat exchanger further comprises two collecting pipes 30, wherein each first pipe segment 11 is connected to one collecting pipe 30 and each second pipe segment 13 is Both are connected to the other collecting pipe 30 . The extending direction of the fins 20 is parallel to the length direction of the collecting tube 30 .

上述したものは本出願の好ましい実施例にすぎず、本出願を制限するためのものではなく、当業者にとって本出願は様々な変更及び変化が可能である。本出願の趣旨及び原則の範囲内でなされた如何なる修正、同等の置換、改良等はいずれも本出願の保護範囲内に含まれるべきである。 The above are only preferred embodiments of the present application and are not intended to limit the present application, which may allow various modifications and changes for those skilled in the art.
