The surface shape of described slot is wavy surfaces, and the top of the wavy surfaces is the second monodentate.
Further, it is connected by the first circular arc camber transition between the first monodentate of each of the combination tooth, it is described
The radius R1 of first circular arc camber is 0.15mm ~ 0.35mm.
Further, it is connected by the second circular arc camber transition between the second monodentate of each of described wavy surfaces,
The radius R2 of second circular arc camber is 0.2mm ~ 0.45mm.
Further, the both ends of the wavy surfaces connect transition, the third by third circular arc camber with tooth is combined
The radius R3 of circular arc camber is 0.1mm ~ 0.3mm.
Further, the addendum angle α of the combination tooth is 20 ° ~ 95 °.
Further, the addendum angle β of first monodentate and the second monodentate is 15 ° ~ 90 °.
Further, the high h of tooth of the combination tooth is 0.25mm ~ 0.8mm, the high H1 of tooth of first monodentate be 0.1mm ~
0.4mm。
Further, the high H2 of tooth of second monodentate is 0.05mm ~ 0.2mm.
Further, the width D of slot is 0.5mm ~ 1mm between described.
The beneficial effects of the utility model are：Setting combination tooth increases connecing for medium and inner wall on the inner wall of riffled tube
Contacting surface is accumulated, while using corrugated structure in slot between combining between tooth, can further increase the surface area of inner wall, is increased
The contact area of medium and inner wall, to improve heat exchanger effectiveness.
