Abstract
The utility model provides a highly effective heat tube, which comprises a tube body, wherein inner screw threads are arranged on the inner surface of the tube body. The heat tube is characterized in that the inner screw threads are in parallel or are basically in parallel with a central axis of the tube body, and an included angle with the central axis of the tube body is controlled with in 0-5degrees, thereby the resistance of air flowing is effectively reduced, the structure is simple, the resistance of the air lowing is little, and the heat tube is in particular suitable in manufacturing computer heat tubes.
Description
Technical field:
The utility model 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:
The purpose of this utility model 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.
The purpose of this utility model 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 the 0-5 degree scope, thereby has effectively reduced the resistance that air flows.
The external diameter of described body is the 3-15.88 millimeter, thickness is the 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 the 0.01-0.07 millimeter, and the height of described internal thread tooth is the 0.05-0.40 millimeter.
The utlity model has simple in structurely, the circulation of air resistance is little, is adapted to make the computer heat pipe especially.
Description of drawings:
