Abstract
The invention provides a heat pipe which comprises a sealed pipe body full of working medium, wherein both ends of the pipe body are dome-shaped sealing heads; the sealing heads and the pipe body form a whole; a through hole is arranged in one of the sealing heads; a plug is inserted on the through hole; and the plug and the sealing head form a whole through high-temperature melting. A manufacturing method of the heat pipe comprises the following steps of: manufacturing a hollow pipe body; manufacturing the sealing heads at two ends of the pipe body; arranging the through hole in one of the sealing heads, and injecting the working medium into the pipe body; inserting the plug in the through hole, wherein a gap is arranged between the plug and the through hole; heating the pipe body until the air in the pipe body is discharged outwards through the gap between the plug and the through hole, stopping the heating; hitting the plug into the through hole, wherein the plug is in interference fit with the through hole; and heating the plug until the plug is melted to enable the plug and the pipe body to form a whole. The heat pipe has the advantages of simplicity in manufacture, seamless sealing heads, long service life and low cost.
Description
Technical field
The present invention relates to a kind of heat pipe and manufacture method thereof.
Technical background
Heat pipe is a kind ofly to fill with working media and utilize the decalescence of medium and the high efficient heat exchanging element that heat exchange is carried out in heat release in the shell of sealing.Existing heat pipe adopts usually has the copper of high-termal conductivity as housing, when producing heat pipe, normally two port punching presses of copper pipe are gradually-reducing shape with punch press, and then form the end socket of heat pipe by argon arc welding welding, certainly will there be weld seam in the heat pipe end socket that this welding forms, will cause the working media in the heat pipe to leak, shorten heat pipe service life.Or the port of copper pipe folder flat become sealing of heat pipe, there is crackle easily in the flat heat pipe sealing of this folder, also can cause the working media in the heat pipe to leak, and shortens heat pipe service life.In addition, two port punching presses of copper pipe are gradually-reducing shape, its complex process, cost height.
Summary of the invention
For overcoming the above-mentioned shortcoming of prior art, it is simple to the invention provides a kind of manufacturing, and end socket is seamless, heat pipe long service life, heat pipe that cost is low and manufacture method thereof.
Heat pipe comprises the body of the sealing that is full of working media, and described body two ends are the end socket of dome shape;
It is characterized in that: described end socket and body are integral, and one of them end socket is provided with through hole, plug a plug on the described through hole, and described plug is integral by melting welding and described end socket.
The manufacture method of described heat pipe may further comprise the steps:
1), makes hollow body;
2), body is clamped in the anchor clamps, drive the body rotation that is clamped in the anchor clamps and to a port heating of body, with the end socket piece push against the body port, with the termination outer rim to the extruding of body axis direction to form dome shape end socket;
3), the upset body, repeating step 2) finish the end socket of another port of body;
4), on an end socket of body, offer through hole, in body, inject working media by described through hole;
5), plug is inserted in the through hole, gapped between plug and the through hole;
6), heating body, the gap of the air in body through between plug and through hole discharge, and stops heating;
7), plug is knocked in the through hole plug and through hole interference fit; Be provided with welding wire between plug and body, the heating plug is until wire melting, and plug and body end socket are integral.
Further, step 2) in, the movement locus of described end socket piece is a circular arc.
Technical conceive of the present invention is: by body is heated to fusing point, be formed at the end socket of body one by spinning body port, and seamless between end socket and the body; With the plug fusion until with the end socket one, seamless between plug and the end socket, thus prevent the working media seepage, prolong the service life of heat pipe.
It is simple that the present invention has manufacturing, and end socket is seamless, heat pipe long service life, the advantage that cost is low.
