Abstract

A heat pipe comprises a sealed pipe body filled with working media, and two ends of the pipe body are both provided with domelike sealing heads which are integrated with the pipe body. One of the sealing heads is provided with a through hole, a plug is inserted in the through hole, and the plug is integrated with the sealing head in fusion welding mode. The heat pipe has the advantages of being simple to manufacture, long in service life and low in cost. The sealing heads have no gaps.

Description

Heat pipe

Technical field

The utility model relates to a kind of heat pipe.

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.

The utility model content

For overcoming the above-mentioned shortcoming of prior art, the utility model provides a kind of manufacturing simple, and end socket is seamless, heat pipe long service life, the heat pipe that cost is low.

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.

Technical conceive of the present utility model is: by body is heated to fusing point, by pushing the end socket that the body port is formed at the body one, 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.

The utlity model has and make simply, end socket is seamless, heat pipe long service life, the advantage that cost is low.

The specific embodiment

With reference to accompanying drawing, further specify the utility model:

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;

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.

Technical conceive of the present utility model is: by body is heated to fusing point, by pushing the end socket that the body port is formed at the body one, 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.

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.

Step 2) in, the movement locus of described end socket piece is a circular arc.

The utlity model has and make simply, end socket is seamless, heat pipe long service life, the advantage that cost is low.

The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.

Claims (1)

1. 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 high-temperature fusion and described end socket.
