Abstract
The utility model discloses an internal thread ultra-thin footpath copper pipe, it is including the internal thread copper pipe of copper intraductal surface equipartition screw thread, its characterized in that: the outer diameter of the internal thread copper pipe is less than 5 mm. The copper pipe greatly enhances the adaptability of the manufacturing process of the evaporator and the condenser, improves the heat exchange effect, can greatly reduce the volume of the heat exchanger, and reduces the copper consumption.
Description
Technical field:
The utility model relates to the ultra-fine copper pipe of internal thread, and particularly a kind of external diameter is widely used in air conditioner, refrigerator, refrigerator and precision type instrument, instrument and electronics industry etc. at the inner screw thread copper pipe below 5 millimeters.
Background technique:
External diameter is extensively made and is used at the inner screw thread copper pipe of 5-10 millimeter at present, makes the overall performance of refrigeration and air-conditioning equipment have increased significantly.Current, the conventional inner screw thread copper pipe of Refrigeration ﹠ Air-Conditioning equipment institute adapted develops to miniaturization, high efficiency lightweight direction, and this develops to the ultra-fine and high efficiency direction of caliber with regard to requiring inner screw thread copper pipe.Owing to multiple reason, also there is not at present external diameter less than 5 millimeters inner screw thread copper pipe application in this respect.
Summary of the invention:
The purpose of this utility model is design a kind of heat transfer efficiency height and external diameter less than 5 millimeters ultra-fine caliber inner screw thread copper pipe.
Technical solution of the present utility model is, it includes the uniform inner screw thread copper pipe of copper pipe internal surface screw thread, and it is characterized in that: the external diameter of described inner screw thread copper pipe is less than 5 millimeters.Because this ultra-fine caliber inner screw thread copper pipe has higher bearing capacity, when satisfying identical temperature conductivity, can also satisfy the requirement thick than thin-walled, this quality that just means unit length is littler, more can save copper material.
Description of drawings:
Fig. 1 is a local straight tube sectional drawing of the present utility model; Fig. 2 is a copper pipe cross section part enlarged view of the present utility model.Symbol among the figure: Hf represents the screw thread tooth depth, and a represents the thread drift angle, and β represents lead angle, and n represents the tooth bar number, and D represents the copper pipe external diameter, and TW represents the copper pipe wall thickness, and d represents the copper pipe internal diameter, and W represents the screw thread bottom width.
Embodiment:
The ultra-fine footpath of a kind of internal thread of the utility model copper pipe, its external diameter are less than 5 millimeters, and I reaches 2.5 millimeters.The shape of cross section of its internal thread tooth is the peach mouth shape of symmetry, is the curve form of arc transition from the tooth top to the tooth root, and the lead angle β of groove is 5-30 °, and tooth depth Hf is the 0.05-0.18 millimeter, and addendum angle a is 15-65 °, and it is the 12-40 bar that the interior tooth bar of pipe is counted n.When making core head, by precision control and employing special material to the tooth top radius and the radius of flute of tooth, draw out the ultra-fine caliber inner screw thread copper pipe of thin-walled, thin footpath, high tooth through the spinning means, this copper pipe has been strengthened the adaptability of vaporizer and condenser manufacturing process greatly, improved the heat exchange effect, can dwindle heat exchanger volume greatly, reduce copper consumption.
Claims (1)
1, the ultra-fine footpath of internal thread copper pipe, it includes the uniform inner screw thread copper pipe of screw thread on the copper pipe internal surface, and it is characterized in that: the external diameter of described inner screw thread copper pipe is less than 5 millimeters.
