Abstract
A kind of welding close contact heat pipe, including by the independent air chamber in the body of extrusion forming, body and being filled by metal material in the working medium of independent air intracavitary, internal spline and side teeth groove are provided with the tube body of heat pipe, internal spline is in the middle part of tube body of heat pipe, side teeth groove is located at tube body of heat pipe both sides, press close to body portion side wall, for each independent air chamber into working medium runner, side wall is externally provided with right angle corner angle.Due to using internal spline, side teeth groove and right angle corner angle, heat-conducting effect being considerably increased, after body produces right-angled edge edged surface, the laser welding of low thermal resistance can be realized with sheet metal, thermal conduction resistance is reduced, heat-transfer effect is enhanced, substantially increases the heat transfer efficiency of heat pipe.
Description
Technical field
This patent is related to a kind of thermal transfer devices, more particularly to a kind of heat transfer unit (HTU) of achievable laser welding.
Background technology
The heat transfer element similar to R.S. Gauler is independently proposed from U.S. Grover in 1964 et al., and
Heat pipe is named, so far the existing history of 40 years.The emphasis of heat pipe application is transferred to ground by space flight, is expanded to by industrial applications
The product for civilian use.Such as the flat hot pipe of capillary structure, using phase-change heat transfer, so as to which its thermal conductivity factor is high, than gold such as silver, copper, aluminium
Category heat conductor is several orders of magnitude higher.In addition, heat pipe is applied in solar energy heat utilization field, also have and start fast, heat transfer property
Good, good antiscale property, use the reliable, advantage such as resistance to frost is good.
At present, flat hot pipe body broad side surface is most uses half round surface, and the heat transfer path that its capillary structure uses is less,
The wider face of body is difficult to transmission of heat by contact with other materials such as sheet metal, and heat transfer property weakens significantly.Moreover, heat pipe and its
It needs the device that conducts heat to couple more using heat conductive silica gel, the method for silicone grease stickup and the method that tightens.
The content of the invention
The present invention is directed to above-mentioned technical problem, it is necessary to provides a kind of flat hot pipe of achievable laser welding.
Technical scheme：
A kind of welding close contact heat pipe, including by metal material by the independent air in the body of extrusion forming, body
Chamber and fill in the working medium of independent air intracavitary, is provided with internal spline and side teeth groove in the tube body of heat pipe, internal spline is located at heating pipe
In the middle part of body, side teeth groove is located at tube body of heat pipe both sides, presses close to body portion side wall, and each independent air chamber is into working medium runner, outside side wall
Provided with right angle corner angle.
A kind of welding close contact heat pipe, it is characterised in that：
A. the body produces the body of the internal spline, side teeth groove and right angle corner angle by the method for continuously extruding and molding,
And be processed by shot blasting, the body can be made up of metal materials such as aluminium or copper；B. the outer surface of the body is carried out and interior
Teeth groove and side teeth groove are cleaned, and dry deaeration；C. described body one end is sealed；D. by the independent air intracavitary
Vacuumize, the independent air intracavitary vacuum is reduced between 0-20Pa, work of the perfusion liquid filled ratio between 19%-28%
Matter, sealing, the working medium can be the lower boiling liquid such as water, alcohol, acetone；E. the body is cleaned and dried after sealing.
A kind of welding close contact heat pipe is due to using internal spline, side teeth groove and right angle corner angle, considerably increasing and leading
Thermal effect, after body produces right-angled edge edged surface, the laser welding of low thermal resistance can be realized with sheet metal, reduce heat conduction heat
Resistance, enhances heat-transfer effect, substantially increases the heat transfer efficiency of heat pipe.

5th, embodiment
Including by the independent air chamber 14 in the body 11 of extrusion forming, body 11 and being filled by metal material in independent air
Working medium 13 in chamber 14, internal spline 12 and side teeth groove is provided with the body 11 of the heat pipe 10, internal spline 12 is located at the body 11 of heat pipe 10
Middle part, side teeth groove 15 are located at the both sides of 10 body of heat pipe 11, press close to the partial sidewall of body 11, each independent air chamber 14 flows into working medium 13
Road, side wall are externally provided with right angle corner angle 16.
Metallic plate 4 is kept flat, heat pipe 10 is then pressed close into metallic plate 4, control front side laser beam emitting head 2 and rear side laser hair
First 3 intersections focused in right angle corner angle 16 and metallic plate 4 are penetrated, driving front side laser beam emitting head 2 and rear side laser beam emitting head 3 are simultaneously
Welding, complete heat pipe 10 and contacted with the welding of metallic plate 4.
