Abstract
The utility model discloses a heat conduction pipe, which comprises a heat conduction pipe body, wherein the heat conduction pipe body comprises an aluminum heat conduction pipe, a stainless steel heat conducting tube and a copper heat conduction pipe, wherein one end of the stainless steel heat conducting tube is connected with the aluminum heat conduction pipe, and the other end of the stainless steel heat conducting tube is connected with the copper heat conduction pipe. The heat conduction pipe is simple and compact in structure, effectively prevents electrochemical corrosion from happening because the copper and the aluminum are not directly welded and connected, and increases melting points of welding positions of stainless steel with the copper and the aluminum to be 420 degrees by arranging the stainless steel, thereby improving practicability.
Description
Technical field
The utility model relates to a kind of heat pipe.
Background technology
Heat pipe has good heat transfer performance, from the heat of one end, can be delivered to rapidly the other end.As shown in Figure 1, have in the market so a kind of heat pipe 1 ', it is welded by copper heat pipe 4 ' and aluminum heat pipe 2 '.Owing to there is potential difference in copper and aluminium, therefore easily generation electrochemical corrosion when copper aluminium welding place runs into wet environment.Therefore for fear of copper aluminium welding place, there is electrochemical corrosion, in use can be at copper aluminium welding place overcoat heat-shrink tube 5 '.If the outer heat-shrink tube 5 ' of installing of heat pipe 1 ' can be made troubles to the installation of heat pipe 1 ', therefore can not fundamentally solve the problem of electrochemical corrosion.And because its fusing point of copper aluminium welding place is generally 280 about degree, once and heat pipe 1 ' temperature surpasses 280 degree it will melt, thereby affect the normal use of heat pipe 1 '.
Utility model content
The purpose of this utility model is to provide a kind of heat pipe, it is simple and compact for structure, because copper aluminium is not directly weldingly connected, effectively avoided the generation of electrochemical corrosion, and stainless setting makes stainless steel bring up to 420 degree with the fusing point of copper, aluminium weld respectively, thus the practicality of raising heat pipe.
In order to achieve the above object, the technical solution of the utility model is:
A kind of heat pipe, comprise heat pipe body, described heat pipe body is comprised of aluminum heat pipe, stainless steel heat pipe, copper heat pipe, and described stainless steel heat pipe one end and aluminum heat pipe are weldingly connected, and the described stainless steel heat pipe other end and copper heat pipe are weldingly connected.
The nozzle diameter of described stainless steel heat pipe upper end is greater than the nozzle diameter of aluminum heat pipe bottom, and described aluminum heat pipe is connected to stainless steel heat pipe top and is weldingly connected in bottom; It is direct that the nozzle diameter of described stainless steel heat pipe bottom is less than the mouth of pipe on copper heat pipe top, and described stainless steel heat pipe is connected to copper heat pipe top and is weldingly connected in bottom.
The Length Ratio of described aluminum heat pipe, stainless steel heat pipe and copper heat pipe is 1 ︰ 1 ︰ 1.
The beneficial effects of the utility model are: a kind of heat pipe, it is simple and compact for structure, because copper aluminium is not directly weldingly connected, effectively avoided the generation of electrochemical corrosion, and stainless setting makes stainless steel bring up to 420 degree with the fusing point of copper, aluminium weld respectively, thus the practicality of raising heat pipe.
Accompanying drawing explanation
Fig. 1 by the market the structural representation of use heat pipe;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
Embodiment 1
A kind of heat pipe as shown in Figure 2, comprise heat pipe body 1, described heat pipe body 1 is comprised of aluminum heat pipe 2, stainless steel heat pipe 3, copper heat pipe 4, described stainless steel heat pipe 3 one end and aluminum heat pipe 2 are weldingly connected, and described stainless steel heat pipe 3 other ends and copper heat pipe 4 are weldingly connected.The nozzle diameter of described stainless steel heat pipe 3 upper ends is greater than the nozzle diameter of aluminum heat pipe 2 bottoms, and described aluminum heat pipe is connected to stainless steel heat pipe 3 tops and is weldingly connected in 2 bottoms; It is direct that the nozzle diameter of described stainless steel heat pipe 3 bottoms is less than the mouth of pipe on copper heat pipe 4 tops, and described stainless steel heat pipe is connected to copper heat pipe 4 tops and is weldingly connected in 3 bottoms.The Length Ratio of described aluminum heat pipe 2, stainless steel heat pipe 3 and copper heat pipe 4 is 1 ︰ 1 ︰ 1.
A kind of heat pipe described in the present embodiment, owing to increasing the setting of stainless steel heat pipe 3, so aluminum heat pipe 2 and copper heat pipe 4 be not directly weldingly connected, and effectively avoided the generation of electrochemical corrosion, also do not need additionally to increase heat-shrink tube.When reducing production costs, also make heat pipe easier for installation.Because stainless steel heat pipe 3 is connected with copper heat pipe 4 with aluminum heat pipe 2 respectively, so stainless steel heat pipe 3 brings up to 420 degree with its fusing point of weld of aluminum heat pipe 2, copper heat pipe 4, thereby greatly improved the practicality of heat pipe.It is general by gas brazing for traditional copper aluminium welding, and the heat pipe that employing gas brazing not only needs butt welding to connect cleans, and has improved production cost, and can cause environmental pollution.And the welding of stainless steel heat pipe 3 and copper heat pipe 4 can adopt the welding of continous way soldering oven, not only improved production efficiency, and avoided cleaning link, thereby avoided environment.The production firm of continous way soldering oven is Shenzhen Heng Yueluye equipment Science and Technology Ltd..
A kind of heat pipe of the present embodiment, it is simple and compact for structure, because copper aluminium is not directly weldingly connected, has effectively avoided the generation of electrochemical corrosion, and stainless setting makes stainless steel bring up to 420 degree with the fusing point of copper, aluminium weld respectively, thus the practicality of raising heat pipe.
