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.

Abstract

The invention discloses a production technology of a high-tooth fin copper heat tube. A product produced by the production technology is composed of copper and copper alloy seamless tubes. High-tooth fins are arranged on the periphery of a main seamless tube, and the high-tooth fins and the main seamless tube are formed in an integral mode. A plurality of regular grooves parallel to a high-tooth fin tube are formed in the inner wall of the high-tooth fin tube. Two ends of the high-tooth fin tube are sealed in a spinning mode. The high negative pressure state is maintained in the high-tooth fin tube. A certain amount of liquid media (distilled water) is poured into the high-tooth fin tube. The technological process of the production technology of the high-tooth fin copper heat tube includes choosing the main seamless tube, one-time forming of the high-tooth fins and the inner wall grooves, sealing the two ends in a spinning mode, pouring the media, heating up and exhausting air, sealing openings in a spinning mode and finishing a product. The production technology of the high-tooth fin copper heat tube is suitable for the field of electric power, energy sources, chemical industry, communication and transportation and the like.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a production process of a high-tooth fin copper heat pipe. Background technique [0002] Phase change heat transfer tube technology is a high-tech developed internationally, and has broad application prospects in energy saving, environmental protection, uniform temperature and heat dissipation. With the rapid development of the economy, the contradiction between energy and environmental protection has become increasingly prominent. Using high-tech to develop energy-saving and environmentally-friendly products, incubating and transforming them into scientific and technological achievements, and using high-tech to operate modern enterprises not only have market competitiveness, but also meet the needs of my country's national economic development. . [0003] At present, heat pipes in the domestic market mostly adopt simple copper, aluminum, steel and other metal light pipes, or are fixed on the outer...
