By adopting the casting connection process, the thermal resistance of the lamp and the heat-conducting pipe is reduced and the heat conduction effect after assembly is ensured; the zero-distance connection of the lamp and the heat-conducting pipe is realized, and the heat conduction performance of a heat radiation structure of the lamp is improved; and the casting operation is more convenient, a clad layer clad on the heat-conducting pipeis more uniform, the casting effect is ensured, and the heat conduction effect is improved.
Description
Technical field
The present invention relates to light fixture heat dissipation technology field, the casting of refering in particular to a kind of lamp heat conducting pipe connects technology.
Background technology
At present, in the street lighting technology, the normal heat pipe that uses in light fixture is to improve the biography radiating effect of light fixture, and the fixing mode basically identical of heat pipe: light source adopts light source liner plate attachment screw rigidity to compress usually, heat pipe is in contact with it, radiator compresses by the cover plate attachment screw usually, and heat pipe is in contact with it.
Yet light source liner plate, heat pipe and radiator manufacturing are to be easy to generate error, cause the contact site gapped, influence effective conduction of heat; And because light source liner plate, heat pipe and radiator adopt unlike material to make, when temperature raise, the coefficient of expansion of unlike material is difference to some extent also, easily therefore and the generation gap influences heat-conducting effect; Radiator and heat pipe are made the oxide that the rear surface generates in addition big thermal resistance, and both when making surface contamination greasy dirt is arranged, both are assembled can reduce heat-conducting effect.
Summary of the invention
For addressing the above problem, the invention provides and a kind ofly connect material as connecting medium by casting, heat pipe is closely contacted with radiator, thereby the casting of the lamp heat conducting pipe of raising heat-conducting effect connect technology.
For achieving the above object, the present invention adopts following technical scheme to be: it is as follows that this casting connects processing step:
One, prepares before the casting, prepare an amount of casting and connect material, heat pipe and radiator and auxiliary mould to be assembled, check calciner;
Two, surperficial removal of impurities is with oxide and the oil removal of heat pipe and spreader surface;
Three, assembling is proofreaied and correct, and the heat pipe justify align is installed on radiator and the light source base, simultaneously auxiliary mould is placed on the rigging position of heat pipe and radiator;
Four, heating casting after casting connect material and be heated to molten condition with calciner high temperature, cooperates auxiliary mould, the casting of fusion is connect material water the corresponding assembly surface that casts from heat pipe and radiator, and be filled in the gap between heat pipe and the radiator;
Five, force cooling, fill finish after, act on casting and connect material by air-cooled, treat that casting connects material cooled and solidifies after, take out auxiliary mould.
It is consistent with the material of making radiator that described casting connects material, and this casting connects the link that material is coated on heat pipe and radiator fully.
Described radiator adopts aluminium alloy to make, the parallel and type groove that has been equally spaced of this spreader surface, and this radiator is connected with heat pipe by this type groove.
The aluminium alloy that described radiator adopts is 6063 materials, and the oxide of this spreader surface and greasy dirt are removed in the nitric acid hydrofluoric acid mixed solution by behind the surface sand-blasting.
Described heat pipe is copper pipe, is filled with heat-conducting medium in this heat pipe, and this heat pipe is a plane with the upper surface of the link of radiator and light source base.
The oxide on the surface of described heat pipe and greasy dirt are removed with organic solvent after handling by sand paper.
Surface alcohol wash after described heat pipe is handled with sand paper.
The heating-up temperature of described calciner is more than 660 ℃.
Described auxiliary mould is a forming blocks, is provided with groove in the middle of this forming blocks, and the cell wall of this groove is the inclined-plane, and four jiaos of this groove are rounding.
The gradient on the inclined-plane of described auxiliary mould is 5 °, and the size that the groove correspondence of this auxiliary mould is placed on the notch on the rigging position of heat pipe and radiator is slightly larger than the size of the notch of the relative side of groove.
Beneficial effect of the present invention is: before casting connect the material casting, the surperficial removal of impurities to heat pipe and radiator had reduced both thermal resistances, had guaranteed the heat-conducting effect after the assembling; Heat pipe after the assembling correction and the gap between radiator are cast, realized that both zero distances connect, and have improved the heat conductivility of radiator structure on the light fixture; Cooperate auxiliary mould in casting cycle, make pouring operation more convenient, the clad that is coated on the heat pipe is more even, has more guaranteed the casting effect, has improved heat-conducting effect.
Description of drawings

Fig. 2 is the vertical view of auxiliary mould of the present invention.
The drawing reference numeral explanation:
1. groove; 2. cell wall.
The specific embodiment
See also shown in Fig. 1-2, the present invention connects technology about a kind of casting of lamp heat conducting pipe, is described further below in conjunction with accompanying drawing:
At first, prepare aluminium alloy that an amount of and radiator make 6063 identical materials of material and connect material, the copper heat pipe that is filled with heat-conducting medium and radiator and auxiliary mould to be assembled as casting, check calciner, can normally use to guarantee the dissolving stove;
Secondly, spreader surface to be assembled is carried out blasting treatment, with to its surface derusting and small burr, oxide and greasy dirt to spreader surface removed in the nitric acid hydrofluoric acid mixed solution again, and, the sand paper that carries out to the surface of heat pipe to be assembled is handled, and the oxide of greasy dirt and the sand paper on heat pipe surface being handled out with organic solvents such as alcohol is removed again, to reduce both thermal resistances;
Then, the heat pipe justify align is installed on radiator and the light source base, assembling is proofreaied and correct, and simultaneously auxiliary mould is placed on the rigging position of heat pipe and radiator, to guarantee the casting effect;
Again, after casting connect material and be heated to molten condition with calciner with the high temperature more than 660 ℃, cooperate auxiliary mould, the casting of fusion is connect material water the corresponding assembly surface that casts from heat pipe and radiator, and be filled in the gap between heat pipe and the radiator, and coat on the heat pipe fully;
At last, wait to cast connect material to the gap between heat pipe and the radiator fill finish after, casting connect material force cooling by air-cooled, treat that casting connects material cooled and solidifies after, take out auxiliary mould.
The casting of disclosed lamp heat conducting pipe connects technology, the parallel and type groove that has been equally spaced of its spreader surface, and this radiator is connected with heat pipe by this type groove, and this heat pipe is a plane with the upper surface of the link of radiator and light source base.
