Embodiment Construction
[0024] As shown in the figure, the production process of the product of the present invention is mainly composed of selecting the mother tube - forming the outer high fins and inner grooves - spinning and closing - injecting medium - heating and exhausting - spinning and sealing - finished products seven steps composed of processes. Among them, the second process adopts special processing technology to form high-toothed fins on the outer surface of high-quality seamless copper tubes and grooves on the inner wall, and the high-toothed fins and grooves are formed at the same time. The third process and the sixth process adopt the special processing technology independently developed, and use the spinning method to shrink the diameter of the two ends of the copper tube until they are welded together to achieve the effect of closing and sealing.
[0025] The invention is applicable to the fields of electric power, energy, chemical industry, transportation and the like.
