It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Please refer to accompanying drawing 2-6 below and describe the utility model in detail in conjunction with the embodiments.
Consider that current fishing lamp radiating effect is not good, light fixture preponderance, high cost, the utility model provides high-powered LED lamp that is lightweight, rapid heat dissipation and is used as fishing lamp.Certainly, this lamp is not limited to as fishing lamp.
the structure structure of light fixture
This high-powered LED lamp, comprises LED illuminating module and radiator, and described LED illuminating module is fixedly mounted on below radiator.Described radiator comprises several radiating aluminium sheet 11, several heat-conducting copper pipe 12 and substrate 13, and substrate 13 is preferably by aluminium die-casting or extruded.
Each described radiating aluminium sheet 11 is vertically set on described substrate 13, and the welding of the base of radiating aluminium sheet 11 is on the substrate, arranged in parallel and be spaced from each other between radiating aluminium sheet 11.
Described each heat-conducting copper pipe is " U " type pipe, top set and the inferior division of its " U " type pipe are horizontally disposed with when mounted, described multiple radiating aluminium sheet is laterally run through along the thickness direction of radiating aluminium sheet in top set, and inferior division is placed in the transverse concave groove 14 that substrate 13 upper surface offers.The cross sectional shape of groove 14 mates with the cross sectional shape of inferior division lower surface, thus when making to install, the lower surface of inferior division can with groove inner surface close contact, promote heat transfer.The base of described radiating aluminium sheet offers the breach mated with the cross sectional shape of described inferior division upper surface.Inferior division is through these breach, thus upper surface and described radiating aluminium sheet base close contact, promote heat transfer.The number of described transverse concave groove and the number of described breach equal the number of described heat-conducting copper pipe.
The multiple perforation of correspondence that confession many heat-conducting copper pipes that the roughly centre position of radiating aluminium sheet comprises lateral arrangement pass, described perforation is formed by punching press, the technique skirt-rim that during punching, cold draw is formed is retained through machining and shaping, forms the multiple annulus contact walls 17 outwardly extended from the side of radiating aluminium sheet.When heat-conducting copper pipe inserts perforation, the annulus contact inner surface of wall 17 contacts with the intimate of heat-conducting copper pipe, increases the contact area between radiating aluminium sheet and heat-conducting copper pipe on the one hand, promotes heat transfer, increase bonding area between heat-conducting copper pipe and radiating aluminium sheet on the other hand, improve weld strength.Similarly, multiple breach on the base of radiating aluminium sheet are also by same Sheet Metal Forming Technology formation process shirt rim, and form semicircular ring contact wall 18 through machining and shaping, when heat-conducting copper pipe inserts breach, the semicircular ring contact inner surface of wall 18 contacts with the intimate of heat-conducting copper pipe, increases the contact area with heat-conducting copper pipe on the one hand, promotes heat transfer, increase the bonding area between heat-conducting copper pipe and radiating aluminium sheet on the other hand, improve weld strength.
The height of described annulus contact wall 17 or semicircular ring contact wall 18 is less than or equal to the spacing between adjacent two radiating aluminium sheets.
As required or aesthetic, heat-conducting copper pipe can be obliquely installed, tilt to be applied on radiating aluminium sheet.Correspondingly, described annulus contact wall 17 contacts wall 18 with semicircular ring needs by inclination punching and is formed.
Radiating aluminium sheet is closely welded on substrate, therefore the lower end of radiating aluminium sheet is provided with the bonding pad 16 of bending.
Because each radiating aluminium sheet is arranged in parallel, have space like this, can form the passage of circulative convection heat radiation, form replacing of air thus, increase thermal convection current efficiency, radiating effect is obvious.
Radiator prepared by the utility model, radiating principle after its radiating aluminium sheet is combined with heat-conducting copper pipe is that hot-air density is little, and hot-air can be gone out by radiator aluminium flake interstitial row, thus, cold air enters radiator inside by sheet aluminum base gap, and forms the exchange of natural air.
Can stablize to make all radiating aluminium sheets and be fixed into an entirety, on the outside of each radiating aluminium sheet, except the limit of the bottom of welding with substrate, every bar limit is provided with brace 15, this brace can be integrated punching when making radiating aluminium sheet, may also be follow-up welding.When described brace 15 is by making the edge pressing and bending of radiating aluminium sheet be formed, bending also forms the corresponding gap 19 of radiating aluminium sheet side while forming brace 15.The end of described brace 15 can snap into the corresponding gap 19 of adjacent heat radiation aluminium flake.When making radiator, by means of brace, the distance between radiating aluminium sheet is kept stable, thus make that the overall structure of radiator is fixed stably to be worked as, can not be at random because being subject to external force extruding.Gap 19 and the brace 15 of radiating aluminium sheet one side can be provided with two or more.

Use LED fishing lamp convenience, safety to be beneficial to staff, can not be laminated structure because of radiating aluminium sheet, have right angle or sharp wedge angle, careless accidental injury or scuffing, be set to arc by corner on left and right two of the upper end of each radiating aluminium sheet.
the internal feature of heat-conducting copper pipe
The utility model heat-conducting copper pipe 12 used adopts the liquefied mixture of multiple inorganic elements to be injected into copper pipe inner chamber as phase change medium, the superconduction copper pipe with high rate heat transport performance formed after sealing moulding.Phase-change material can be such as yttrium barium copper oxide material, thallium barium calcium copper oxygen material etc., preferably, adopt the water base superconductive liquid medium comprising the compositions such as zinc permanganate, magnesium chloride hexahydrate, sodium tetraborate, potassium bichromate, titanium dioxide, such as containing zinc permanganate 5 parts, magnesium chloride hexahydrate 12 parts, sodium tetraborate 18 parts, potassium bichromate 10 parts, frerrous chloride 3 parts, the water base superconductive liquid medium of 1000 parts, water.Certainly, the utility model does not do too much restriction to the composition of phase change medium, according to the experiment of applicant, as long as superconductor heat conduction is rapid, the heat of aluminium sheet can be delivered to the speed of 300,000 W/M.K the design requirement that radiating aluminium sheet 11 can meet the utility model light fixture.
Because superconductor heat-transfer rate is fast, therefore integral heat sink speed fast (pin temperature rise < 45 DEG C), the radiating aluminium sheet area of dissipation of required radiator is little, lightweight.As mentioned before, adopt same heat spreader structures to realize general power 300W cooling requirements, if adopt conventional thermal conductive copper pipe, need about 10500cm
2area of dissipation, namely every watt needs 35cm
2area of dissipation, volume is about 0.0072m3.And if adopt superconduction copper pipe, only need about 5973cm
2area of dissipation, namely every watt needs 20cm
2area of dissipation, volume is about 0.0046m3, has saved the area of dissipation of 42.8% and the volume of 36%.

When using as fishing lamp or other light fixtures, the performance of above-mentioned capillary structure on light fixture has significant impact.Therefore, in light fixture use procedure, lamp holder usually can need to rotate.If there is no capillary structure, we know, in order to meet the space requirement of phase-change material phase transformation, in heat-conducting copper pipe, only some space is filled with phase-change material, if lamp holder rotates exceed certain angle, if the heat-conducting copper pipe part contacted with substrate is without phase-change material, then the heat of substrate cannot be taken away by phase-change material in time, therefore can produce significant heat build-up on substrate, this will bring serious damage to the high-powered LED lamp producing a large amount of heat load instantaneously.
By arranging capillary structure in heat-conducting copper pipe inside, phase-change material can relatively uniformly be distributed on the length direction of heat-conducting copper pipe, therefore no matter how lamp holder direction rotates, the position that heat-conducting copper pipe contacts with samming aluminium sheet always has heat transfer medium to be existed, or by capillarity, the liquid phase phase-change material at other positions is added to corresponding site.Therefore heat transfer medium undergoes phase transition rapidly and other positions of the heat-conducting copper pipe that led fast by heat after receiving the heat that samming aluminium sheet passes over, and is then distributed by heat by means of radiating aluminium sheet.
LED fishing lamp prepared by the utility model, under duty, the substrate of LED illuminating module held against heat sink, substrate plays samming effect, heat-conducting copper pipe is close to aluminium sheet, heat is passed to radiating aluminium sheet with 300,000 W/M.K heat transfer rates by the heat of aluminium sheet rapidly, and whole radiating aluminium sheet always remains high temperature and equal temperature state, and heat transfer rate can not be affected because lamp holder rotates.
