内面に凹凸やインナーフィンを設けた形状としている。As shown in FIG. 3, the serpentine heat exchanger has a structure in which flat heat exchanger tubes 1 are bent into a meandering shape, and corrugated fins 2 are sandwiched between them. For the purpose of increasing the heat transfer performance of the heat exchanger, the flat heat exchanger tube has a shape in which irregularities and inner fins are provided on the inner surface of the passage hole as described in Utility Model Application Laid-open No. 59-148970.

Since n is the same, when the flat heat exchanger tube 1 is bent into a meandering shape, the center column 1a closest to both ends is buckled and deformed, as shown in FIGS. 5 and 6, and both ends of the flat heat exchanger tube 1 are There was a drawback that the outer peripheral portion 1c was crushed and the fluid passage became narrow, making it difficult for fluid to flow, resulting in a decrease in the amount of heat exchanged by the heat exchanger.

熱交換器の交換熱量が減少してしまうという問題があっ
た。In the above-mentioned conventional technology, when a flat heat exchanger tube with unevenness and inner fins provided in the inner concavity of the fluid passage hole is bent into a serpentine shape, the center pillars closest to both ends are buckled and deformed, causing the flat heat exchanger tube to collapse. The fluid passage becomes narrower, making it difficult for fluid to flow.
There was a problem in that the amount of heat exchanged by the heat exchanger decreased.
本発明の目的は偏平伝熱管の両端部に最も近い中柱の座
屈変形を防ぎ、偏平伝熱管のっぷれをなくすることによ
り、熱交換器の交換熱量の減少を防止することにある。An object of the present invention is to prevent a reduction in the amount of exchanged heat of a heat exchanger by preventing buckling deformation of the central pillars closest to both ends of a flat heat exchanger tube and eliminating bulges in the flat heat exchanger tube.
上記目的を達成するため、偏平伝熱管の両端部に最も近
い中柱の肉厚を他の中柱の肉厚より厚くした。In order to achieve the above object, the wall thickness of the middle pillar closest to both ends of the flat heat exchanger tube was made thicker than the wall thickness of the other middle pillars.

ができる。When a flat heat exchanger tube is bent into a serpentine shape, the greatest compressive force is applied to the middle pillars closest to both ends, so by making the wall thickness of that middle pillar thicker than the other middle pillars, the stress can be alleviated. As a result, the middle pillars closest to both ends are not buckled and deformed, and the flat heat exchanger tube can be prevented from collapsing.

FIG. 1 is a sectional view of a flat heat exchanger tube 1 of the heat exchanger shown in FIG. 3, in which an inner fin 1b is provided in the fluid passage hole.

ができる。When this flat heat exchanger tube 1 is bent into a serpentine shape, a larger compressive force is applied to the inner pillars closest to both ends than the other middle pillars. Since it is thicker than the wall thickness of the pillar, the middle pillar closest to both ends does not undergo buckling deformation as shown in FIG. As a result, the outer peripheries at both ends of the flat heat exchanger tube 1 are not crushed, the fluid passages are not narrowed, and the amount of heat exchanged by the heat exchanger can be prevented from decreasing.
