The heat exchanger 1 is configured by connecting three heat exchanger components 10 a, 10 b, and 10 c with a connecting resin 11. Of the three heat exchanger components 10 a, 10 b, and 10 c, the uppermost one heat exchanger component 10 a is divided by dividing the fins 20, thereby reducing the size of the number of stages.
Here, the heat exchanger 1 and the heat exchanger components 10a, 10b, and 10c correspond to the heat exchanger of the present invention.

図３は、本発明の実施の形態１に係るフィン２０を分割する様子を示す図である。
熱交換器部品１０ａ、１０ｂ、１０ｃは、断面形状がアスペクト比の大きい長方形を角取りした形状で、内部を冷媒が流れる扁平管３０と、この扁平管３０が挿入される複数の板状のフィン２０と、を有する。
フィン２０には、フィン２０の側端部から、長手方向に直交する幅方向にＵ字状に形成されたスリット２２が形成されている。扁平管３０は、スリット２２に挿入される。FIG. 3 is a diagram showing how the fins 20 according to Embodiment 1 of the present invention are divided.

なお、切込み２１の形状はこれに限られず、線状、矩形、Ｕ字状などであってもよい。
ここで、切込み２１は、本発明の分割可能構造に相当する。As shown in the upper diagram of FIG. 3, the fin 20 has a cut 21 before the fin 20 is divided.
The cuts 21 are formed so as to extend in the width direction orthogonal to the longitudinal direction from the side end of the fin 20 on the opposite side to the slit 22. The cuts 21 are formed in the slits 22 at a predetermined distance in the longitudinal direction of the fins 20.
The incision 21 has a triangular shape, and is formed in a fragile portion that is scheduled to divide the fin 20 in the longitudinal direction and is easy to cut. The cuts 21 cut the fin 20 along the width direction orthogonal to the longitudinal direction, and divide the fin 20 in the longitudinal direction.

Here, the cut 21 corresponds to the splittable structure of the present invention.

図３上図に示すように、切込み２１を入れたフィン２０は、スリット２２を扁平管３０に挿入される。
その後、図３下図に示すように、分割された熱交換器部品１０ａを作成するために全てのフィン２０を切込み２１で分割する。
また、同様に図３下図に示すように、熱交換器部品１０ａ、１０ｂ、１０ｃの連結のために連結樹脂１１を嵌め込む必要がある部分の複数枚（具体的には２〜４枚（４〜１０ｍｍ幅））のフィン２０を切込み２１で切り取る。
このとき、フィン２０に切込み２１が入っているため、容易に切り取りでき、不要となったフィン部分を抜くことができる。

After that, as shown in the lower diagram of FIG.
Similarly, as shown in the lower diagram of FIG. 3, a plurality of pieces (specifically 2 to 4 pieces (4 To 10 mm width)).
At this time, since the cuts 21 are formed in the fins 20, the fins can be easily cut out and the unnecessary fin portions can be pulled out.
In addition, since the strength of the fin 20 after being inserted into the flat tube 30 is weak at the cut 21, it can be easily divided and cut by applying an external force such as bending.

図４は、本発明の実施の形態１に係るフィン２０を分割して熱交換器部品１０ａを分割する様子を示す図である。
図４に示すように、図３の全てのフィン２０を長手方向に段数の分割を実施することで、熱交換器部品１０ａを分割し、熱交換器部品１０ａの段数のサイズを小さくすることができる。FIG. 4 is a diagram showing a state in which the heat exchanger component 10a is divided by dividing the fin 20 according to Embodiment 1 of the present invention.

フィン抜き箇所１２では、フィン２０が切り取られ、扁平管３０のみが他の部分と連続している。フィン抜き箇所１２は、１辺に複数箇所形成される。On the other hand, FIG. 5 is a view showing the heat exchanger component 10b in which the fin 20 according to Embodiment 1 of the present invention is divided and the finned portion 12 is provided.
As shown in FIG. 5, a plurality of fins 20 (specifically, 2 to 4 pieces (4 to 10 mm width)) of fins 20 that need to be fitted with the connecting resin 11 are cut out, thereby providing the finned portion 12. It has been.
At the finned portion 12, the fin 20 is cut off, and only the flat tube 30 is continuous with other portions. A plurality of finned portions 12 are formed on one side.

図６Ａは、本発明の実施の形態１に係るフィン抜き箇所１２に連結樹脂１１を嵌め込んで複数の熱交換器部品１０ａ、１０ｂを連結する様子を示す断面図である。図６Ｂは、本発明の実施の形態１に係るフィン抜き箇所１２に連結樹脂１１を嵌め込んで複数の熱交換器部品１０ａ、１０ｂを連結する様子を示す上面図である。
図６Ａおよび図６Ｂに示すように、フィン抜き箇所１２に連結樹脂１１を嵌め込んで複数の熱交換器部品１０ａ、１０ｂ、１０ｃを連結する。連結樹脂１１は、フィン２０のスリット２２と同様に側端部から長手方向に直交する幅方向にＵ字状に形成されたスリット１１ａを有する。そして、隣り合う熱交換器部品１０ａ、１０ｂ、１０ｃのフィン抜き箇所１２を連続させ、その連続させた２つのフィン抜き箇所１２にわたって連結樹脂１１を嵌め込む。
ここで、連結樹脂１１が本発明の連結部材に相当する。FIG. 6A is a cross-sectional view showing a state where a plurality of heat exchanger components 10a and 10b are connected by fitting connection resin 11 into finned portion 12 according to Embodiment 1 of the present invention. FIG. 6B is a top view showing a state in which the connecting resin 11 is fitted into the finned portion 12 according to Embodiment 1 of the present invention to connect the plurality of heat exchanger components 10a and 10b.
As shown in FIGS. 6A and 6B, a plurality of heat exchanger components 10a, 10b, and 10c are coupled by fitting a coupling resin 11 into the finned portion 12. Similarly to the slits 22 of the fins 20, the connecting resin 11 has slits 11 a formed in a U shape in the width direction perpendicular to the longitudinal direction from the side end portions. Then, the finned portions 12 of the adjacent heat exchanger components 10a, 10b, and 10c are made continuous, and the connecting resin 11 is fitted over the two continuous finned portions 12.
Here, the connecting resin 11 corresponds to the connecting member of the present invention.

図７は、本発明の実施の形態１に係る曲げ加工前の熱交換器１を示す図である。
図７に示すように、分割されて段数のサイズが小さくなった熱交換器部品１０ａと、その他の熱交換器部品１０ｂ、１０ｃと、がフィン抜き箇所１２に嵌め込まれた連結樹脂１１によって連結されて１つの熱交換器１が構成される。
図７に示す熱交換器１は、その後に曲げ加工が実施され、図２に示す熱交換器１が完成する。
なお、熱交換器１のその後の曲げ加工は、三面曲げ、二面曲げ、四面曲げであってもよい。また、熱交換器１は、曲げ加工されない状態で完成されるものであってもよい。
このように、熱交換器１は、フィン２０を切込み２１で分割することができ、フィン抜き箇所１２を形成して複数の熱交換器部品１０ａ、１０ｂ、１０ｃを連結したり、熱交換器部品１０ａを分割したりすることができ、異なる段数のサイズに容易に変更できる。FIG. 7 is a diagram showing the heat exchanger 1 before bending according to Embodiment 1 of the present invention.
As shown in FIG. 7, the heat exchanger component 10 a that has been divided to reduce the size of the number of stages and the other heat exchanger components 10 b and 10 c are connected by a connecting resin 11 that is fitted into the finned portion 12. Thus, one heat exchanger 1 is configured.
The heat exchanger 1 shown in FIG. 7 is then bent to complete the heat exchanger 1 shown in FIG.
The subsequent bending process of the heat exchanger 1 may be three-surface bending, two-surface bending, or four-surface bending. The heat exchanger 1 may be completed without being bent.
Thus, the heat exchanger 1 can divide the fins 20 by the notches 21 and form the finned portions 12 to connect the plurality of heat exchanger parts 10a, 10b, 10c, or to heat exchanger parts. 10a can be divided and can be easily changed to a different number of stages.

ここで、切込み２１の位置を自在に変更することにより、熱交換器１の段数を容易に変更できる。   Here, the number of stages of the heat exchanger 1 can be easily changed by freely changing the position of the cut 21.

また、切込み２１を入れたフィン２０を使用した熱交換器１において、熱交換器１を分割しなかった位置の切込み２１にて、熱交換器１の強度が弱くなる。
分割しない熱交換器１では、フィン２０と扁平管３０の炉中ろう付け工程において、切込み２１にろう材を配置することにより、切込み２１にろう付けを実施し、フィン２０を溶融したろう材で補強し、フィン２０の強度を確保することができる。
また、炉中ろう付け工程以外であっても、切込み２１にろう材を配置することにより、バーナーなどで切込み２１にろう付けを実施し、フィン２０を溶融したろう材で補強し、フィン２０の強度を確保することができる。
ここで、ろう材が本発明の補強部材に相当する。Further, in the heat exchanger 1 using the fins 20 with the cuts 21, the strength of the heat exchanger 1 becomes weak at the cuts 21 at positions where the heat exchanger 1 is not divided.
In the heat exchanger 1 that is not divided, in the furnace brazing process of the fins 20 and the flat tubes 30, the brazing material is disposed in the notches 21, so that the notches 21 are brazed and the fins 20 are melted with the brazing material. The strength of the fins 20 can be ensured by reinforcement.
In addition to the brazing process in the furnace, by placing the brazing material in the notch 21, the notch 21 is brazed with a burner or the like, and the fin 20 is reinforced with the molten brazing material. Strength can be secured.
Here, the brazing material corresponds to the reinforcing member of the present invention.
