Abstract
The invention discloses an inner threaded copper tube with the diameter phi of 3, belonging to inner threaded copper tubes. The inner threaded copper tube with the diameter phi of 3 has the following concrete parameter requirements: the roughness of the copper surface outside the threaded tube is 0.02Ra, the grams per meter is 19-22g/m, the outer diameter phi is 3, the tooth number is 22, the spiral angle is 15 degrees, the addendum angle is 20-40 degrees, the addendum arc r is equal to 0.03m, the bottom arc r is equal to 0.02mm, the bottom wall thickness is 0.18-0.22 mm, the total wall thickness is 0.33-0.36 mm, the tooth height is 0.13-0.17mm, the intertooth space is 0.20mm, the spiral angle is 15 degrees, and the like. Compared with the prior, the inner threaded copper tube with the diameter phi of 3 has the characteristics of large inner surface area, small outer diameter and the like, the energy efficiency ratio is improved, and the inner threaded copper with the diameter phi of 3 has very good popularization and application values.
Description
Technical field
The present invention relates to a kind of inner screw thread copper pipe, Φ 3 inner screw thread copper pipes that the condensation of especially a kind of air conditioner refrigerating industry, heat abstractor are used.
Background technology
Inner screw thread copper pipe has been widely used in the condensation of air conditioner refrigerating industry, heat radiation aspect, and along with the requirement of scientific technological advance, inner screw thread copper pipe develops to directions such as thin footpath, thin-walled, tooth depth, energy-saving and environmental protection.Usually the external diameter of the present inner screw thread copper pipe of producing is thick, and consumable quantity is big, has caused waste, has increased production cost.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of Φ 3 inner screw thread copper pipes at above-mentioned deficiency of the prior art, and these Φ 3 inner screw thread copper pipes have when having reduced production cost, have realized that inner surface area is big, and outside dimension is little, has improved the characteristics of Energy Efficiency Ratio.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the outer roughened copper surface degree 0.02Ra of screwed pipe, the heavy 19-22g/m of Mick, external diameter Φ 3, the number of teeth 22,15 ° of helical angles, 20 °-40 ° of addendum angles, tooth top circular arc r=0.03mm, circular arc r=0.02mm at the bottom of the tooth, the thick 0.18-0.22mm of diapire, total wall thickness 0.33-0.36mm, tooth depth 0.13-0.17mm, space width 0.20mm, 15 ° of helical angles etc.
Φ 3 inner screw thread copper pipes of the present invention are compared with prior art, and have following outstanding beneficial effect: inner surface area is big, and outside dimension is little, when having improved Energy Efficiency Ratio, have realized that inner surface area is big, and outside dimension is little, has improved characteristics such as Energy Efficiency Ratio.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of Φ 3 inner screw thread copper pipes;
The specific embodiment
With reference to explaining below 1 pair of Φ 3 inner screw thread copper pipes work of the present invention of Figure of description.
Φ 3 inner screw thread copper pipes of the present invention, its technical parameter requires: after overmolding draws, screwed pipe outer surface roughness 0.02Ra, the heavy 19-22g/m of Mick, external diameter Φ 3, the number of teeth 22,15 ° of helical angles, 20 °-40 ° of addendum angles, tooth top circular arc r=0.03mm, circular arc r=0.02mm at the bottom of the tooth, the thick 0.18-0.22mm of diapire, total wall thickness 0.33-0.36mm, tooth depth 0.13-0.17mm, space width 0.20mm, 15 ° of helical angles etc.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
