A cut in the lengthwise direction is provided in the center of the width of the plate-shaped connecting portion in the two bent portions, and the first heat exchange tube portion and the second heat exchange tube portion on both sides of the cut portion of the bent portion are X-shaped when viewed from the side surface. Because it is twisted and crossed over,
The fluid passages on the wind-in side and the wind-out side of the heat exchanger are reversed at the bent portion in the middle of the heat exchange pipe, so that the temperature of the cooling air is lower than the one end of the heat exchanger. The fluid flowing through the flow passage in the passage on the air outlet side where the temperature of the cooling air on the opposite side is higher than the X-shaped bent portion and reaches the other end of the heat exchanger, while cooling from one side of the heat exchanger. The fluid flowing in the passage on the outlet side where the temperature of the wind is high flows through the passage on the inlet side where the temperature of the cooling air on the opposite side is lower than the X-shaped bent portion to the other end of the heat exchanger. Therefore, the amount of condensation between the air passages on the air inlet side and the air outlet side can be averaged, and the liquid fluid condensed especially on the air inlet side of the heat exchanger is accumulated in the passages. Therefore, the heat transfer is sufficiently performed and the heat exchange efficiency is greatly increased.

れて、熱交換効率が大幅に増大する。Effect of the Invention As described above, according to the present invention, a flat heat exchange tube made of an aluminum extruded material having a fluid passage is bent in a meandering shape when viewed from the front, and a forced air blow causes air to flow in a direction orthogonal to the fluid passage. In the heat exchanger described above, the meandering heat exchange pipe includes a first heat exchange pipe part and a second heat exchange pipe part having a fluid passage, and a plate-like connecting part provided between the heat exchange pipe parts. A longitudinal cut is provided in the width center of the plate-like connecting portion in at least one bent portion of the meandering heat exchange tube, and the first heat exchange tube portion and the second heat exchanger on both sides of the cut portion of the bent portion. The exchange tube portion is twisted in an X shape when viewed from the side, and the refrigerant passages on the wind inlet side and the wind outlet side of the meandering heat exchange tube are reversed at the bent portion in the middle of the heat exchange tube. Therefore, the temperature of the cooling air is lower than the one end of the meandering heat exchange tube. The refrigerant that has flowed in the air inlet side passage flows in the air outlet side passage where the temperature of the cooling air on the opposite side is higher than the X-shaped bent portion, and reaches the other end of the meandering heat exchange tube. On the other hand, the refrigerant flowing in the passage on the air outlet side where the temperature of the cooling air is higher than the one end of the meandering heat exchange tube is the passage on the air inlet side where the temperature of the cooling air on the opposite side is lower than the X-shaped bent portion. Since it flows through the inside to reach the other end of the meandering heat exchange tube, it is possible to average the amount of condensation between the air passage side and the air outlet side passage of the meandering heat exchange tube. The condensed liquid refrigerant at 1 is not accumulated in the passage, so that the heat transfer is sufficiently performed and the heat exchange efficiency is significantly increased.

ねじ曲げや蛇行状の折曲げ作業は、これを容易に行ない
得るものであるから、熱交換器の製作が容易である。In addition, the surface of the heat exchange tube is reversed between the first heat exchange tube section and the second heat exchange tube section on both sides of the notch provided in the plate-shaped connecting portion of the portion to be bent of the heat exchange tube. As described above, the heat exchange tube may be bent in an X shape as viewed from the side, and then the heat exchange tube may be bent in a meandering shape as viewed from the front. This kind of screw bending or meandering bending work can be easily performed. Therefore, the heat exchanger can be easily manufactured.
しかも板状連結部に切込みが設けられることによって、
ねじ曲げるべき熱交換管部分の幅が狭いものとなされて
いるから、Ｘ状のねじ曲げ部における第１熱交換管部分
と第２熱交換管部分の曲率半径が非常に小さいものとな
り、従って第１および第２熱交換管部分が側方に大きく
突出するようなことがなく、熱交換器は非常にコンパク
トである、という効果を奏する。Moreover, by providing the notch in the plate-like connecting portion,
Since the width of the heat exchange tube portion to be twisted is made narrow, the radius of curvature of the first heat exchange tube portion and the second heat exchange tube portion in the X-shaped threaded portion is very small, and therefore the first and the second The second heat exchange tube portion does not largely project laterally, and the heat exchanger is very compact.
