Abstract
The invention provides a high effective heat pipe comprising a pipe body which is provided with female threads on the inner surface thereof, characterized in that the female threads are parallel to or substantially parallel to the central axis of the pipe body, and the included angle between the female threads and the central axis is controlled within 0-5 degrees, thereby effectively reducing resistance of air flowing. The invention is provided with simple structure and small air flowing resistance, and is particularly adaptive to production of computer heat pipes.
Description
Technical field:
The present invention relates to a kind of riffled tube.
Background technology:
The internal thread of existing riffled tube the inside mostly is oblique internal thread, be to have bigger angle between the axis of internal thread and pipe, this riffled tube has heat dispersion preferably, be specially adapted to refrigerating field uses such as air-conditioning, but air flow resistance is big, not too is applicable to make the computer heat pipe.
Summary of the invention:
Purpose of the present invention is exactly to provide a kind of at above-mentioned situation can adapt to the high-efficiency heat pipe of making the computer heat pipe.
Purpose of the present invention can realize by following scheme, comprise body, inner surface at body is provided with internal thread, it is characterized in that described internal thread is parallel or substantially parallel with the axis of body, angle between the axis of itself and body is controlled in 0-5 degree scopes, thereby has effectively reduced the resistance that air flows.
The external diameter of described body is 3-15.88 millimeters, thickness is 0.15-0.70 millimeter, the number of teeth of described internal thread is 30-80, the tooth top of described internal thread can be designed to plane or cambered surface, its root adopts circular arc excessive, the radius of described circular arc is 0.01-0.07 millimeter, and the height of described internal thread tooth is 0.05-0.40 millimeter.
The present invention has simple in structure, and the circulation of air resistance is little, is adapted to make the computer heat pipe especially.
Description of drawings:
Fig. 1, longitudinal sectional drawing of the present invention
Fig. 2, view in transverse section of the present invention
The specific embodiment:
Contrast Fig. 1, Fig. 2 the present invention includes body 1 as can be known, are provided with internal thread 2 at the inner surface of body 1, it is characterized in that described internal thread 2 is parallel or substantially parallel with the axis of body 1, and the angle between the axis of itself and body 1 is controlled in 0-5 degree scopes.
The external diameter of described body 1 is 3-15.88 millimeters, thickness is 0.15-0.70 millimeter, the number of teeth of described internal thread is 30-80, the tooth top of described internal thread can be designed to plane or cambered surface, its root adopts circular arc excessive, the radius of described circular arc is 0.01-0.07 millimeter, and the height of described internal thread tooth is 0.05-0.40 millimeter.
Described body 1 is made by copper or Cu alloy material.
