Embodiment Construction
[0043] Such as Figure 1-4 As shown, the present invention provides a heat exchange tube, which includes:
[0044] The tube base 1 and the V-shaped tooth 2 arranged on the inner wall of the tube base 1, the V-shaped tooth 2 is a tooth structure protruding inward from the inner wall of the tube base 1, and perpendicular to the In the section of the extending direction of the V-shaped tooth 2, the shape of the V-shaped tooth 2 is V-shaped.
[0045] In the present invention, a V-shaped tooth structure protruding toward the inside is provided on the inner wall of the tube base of the heat exchange tube. The inner wall becomes larger, and the fluid boundary layer near the wall of the heat exchange tube is stretched thinner, which reduces the heat transfer resistance, so the thickness of the fluid boundary layer in the heat exchange tube can be effectively reduced, thereby increasing the degree of fluid turbulence. The heat exchange in the tube is effectively enhanced, and there i...
