Definitions

  • the present invention relates to a flexible tube made of alloy material, in particular, an ultra-thin flexible tube made of an alloy which can substitute common copper tube and is applicable for heat emission in air-conditioning and refrigeration.
  • the present invention also relates to the manufacture process of said ultra-thin flexible tube.
  • evaporators or radiators for current air-conditioning, refrigeration, fridge and heat emission are produced by copper tubes.
  • Copper tubes have fine processability, high capability of heat dissipation and corrosion resistance. It is common knowledge that copper resource is gradually decreasing and its price is higher. The scarcity and high expense of copper resource becomes a bottle neck of material supply in the whole industry.
  • the present invention provides an ultra-thin flexible tube made of an alloy consisting of, in % by weight, Cr: 17 to 23, Ti: 0.1 to 0.35, Cu: 0.4 to 8.5, Mo: 0.2 to 2.4, Co: 0.01 to 0.06, Ni: 0.3 to 2.0, Nb: 0.2 to 1.0, V: 0.05 to 0.4, B: 0.001 to 0.020, Si: ⁇ 1.0, Mn: ⁇ 1.0, C: ⁇ 0.020, N: ⁇ 0.020, P: ⁇ 0.035, S: ⁇ 0.025, Mg: ⁇ 0.005, O: ⁇ 0.006, Al: ⁇ 0.08, and the balance of Fe and inevitable impurities, with hardness HV 90 to 150, elongation rate 25% to 40% and chlorine ion resistance exceeding 100ppm under normal temperature.

  • the tube could be used as a high-efficiency radiating tube in various air conditioners or refrigerating apparatus.
  • Another objective of the present invention is to provide a method of manufacturing said ultra-thin alloy flexible tube comprising steps of:
  • the composition of the alloy in above embodiments of the invention contains large dose of individual master element and small dose of various beneficial master elements meets welding performance requirement for making ultra-thin tubes.
  • This one-piece configured ultra-thin alloy tube in accordance with the present invention possess industrial practical applicability with wall thickness of 0.04 mm to 0.2 mm, and its performance solves problems due to deficient performance of the copper tubes.
  • Its chloride ion resistance is greater than 100ppm, which is about 50% higher than that of copper material. Therefore, the corrosion resistance is improved by 2 to 5 times and the strength is improved by about one time.
  • its ductility is nearly similar to copper alloy material and its heat dissipation performance is high than that of existing tube made of copper alloy. It is a high-efficient tube, which can substitute current copper tube, has performance superior to current copper tube and can meet heat emission requirement of various air-conditioning and refrigerating devices.
  • One preferred embodiment in accordance with the present invention is an ultra-thin flexible tube made of an alloy having an outside diameter of 5.3 mm and a wall thickness of 0.12 mm.
  • Said alloy consists of, in % by weight, Cr: 18, Ti: 0.15, Cu: 0.6, Mo: 1.0, Co: 0.02, Ni: 0.6, Nb: 0.5, V: 0.1, B: 0.005, Si: ⁇ 0.10, Mn: ⁇ 0.24, C: ⁇ 0.004, N: ⁇ 0.005, P: ⁇ 0.006, S: ⁇ 0.002, Mg: ⁇ 0.001, O: ⁇ 0.003, Al: ⁇ 0.05, and the balance of Fe and inevitable impurities, with hardness HV 120, elongation 35% and chlorine ion resistance 200ppm under normal temperature.
  • Said preferred embodiment in accordance with the present invention also provides a manufacturing method of said alloy flexible tube.
  • the method comprises steps of:
  • Another embodiment in accordance with the present invention provides an alloy flexible tube having an outside diameter of 9.52 mm and a wall thickness of 0.15 mm or 0.18mm.
  • Said alloy made into said flexible tube consists of, in % by weight, Cr: 19, Ti: 0.3, Cu: 8.0, Mo: 0.5, Co: 0.1, Ni: 1.0, Nb: 0.5, V: 0.1, B: 0.003, Si: ⁇ 0.10, Mn: ⁇ 0.2, C: ⁇ 0.003, N: ⁇ 0.003, P: ⁇ 0.006, S: ⁇ 0.002, Mg: ⁇ 0.001, O: ⁇ 0.003, Al: ⁇ 0.05, and the balance of Fe and inevitable impurities, with hardness HV 110, elongation 40% and chlorine ion resistance 100ppm under normal temperature.
