Abstract

The invention discloses a copper heat tube with high-tooth fins and production technology of the copper heat tube. The copper heat tube comprises a copper and copper alloy seamless tube, the high-tooth fins which are spirally wound around a tube body are arranged on the periphery of the seamless base tube and are structurally integrated with the seamless base tube, a plurality of regular grooves which are parallel to the tube are arranged on the inner wall of each high-tooth fin, two ends of the copper tube are sealed by nuts, the inside of the copper tube is vacuum, and a certain quantity of liquid (distilled water) is filled into the tube. The technological process includes selecting the base tube; simultaneously molding the high-tooth fins and internal threads; vacuumizing and filling the liquid into the tube; sealing the copper tube by the nuts; and obtaining a finished product. The copper heat tube and the production process are applicable to the fields of electric power, energy resources, chemical engineering, transportation and the like.

Description

technical field [0001] The invention relates to a heat pipe, in particular to a high-tooth fin copper heat pipe and its production process. 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 ou...
