Abstract
The utility model provides a screw thread copper pipe, including the body, characterized by last highly the same first internal thread tooth, second internal thread tooth and the third internal thread tooth of alternately being equipped with of pipe inner wall, first internal thread tooth is apart from the shape tooth, second internal thread tooth is thick high tooth, and its addendum angle is alpha a, and the angle is 30 - 40 degrees, third internal thread tooth is thin high tooth, and its addendum angle is alpha b, and the angle is 10 - 20 degrees. Because the utility model discloses pipe inner wall is last to be equipped with three kinds of internal thread teeth, utilizes three kinds of respective advantages of internal thread tooth to influence alternately the refrigerant to improve the radiating effect. The utility model has the characteristics of simple structure, the radiating effect is good etc.
Description
Technical field
The utility model relates to a kind of screw thread copper pipe.
Background technology
At present, the screw thread of screw thread copper pipe is all the screw thread being designed to a kind of flute profile aligned transfer as required, and its main flute profile has full depth tooth, tall and thin tooth, intersection tooth etc., for improving heat transfer efficiency.The screw thread copper pipe of this monodentate type, its radiating effect is bad.
Utility model content
The purpose of this utility model is exactly the screw thread copper pipe providing a kind of good heat dissipation effect for above-mentioned situation.The purpose of this utility model realizes by following scheme: a kind of screw thread copper pipe, comprise body, it is characterized in that described inboard wall of tube body intersects being provided with the first highly identical internal thread tooth, the second internal thread tooth and the 3rd internal thread tooth, described first internal thread tooth is that described second internal thread tooth is thick high tooth, and its addendum angle is α a apart from shape tooth, angle is 30-40 degree, described 3rd internal thread tooth is tall and thin tooth, and its addendum angle is α b, and angle is 10-20 degree.Because the utility model inboard wall of tube body is provided with three kinds of internal thread teeth, utilize three kinds of internal thread teeth advantage separately to carry out reciprocal effect to refrigerant, thus improve radiating effect.It is simple that the utility model has structure, the features such as good heat dissipation effect.
Accompanying drawing explanation
Fig. 1, the utility model sectional view.
