Description
Technical field
The present invention relates to a kind of LED high-power light-projecting lamps technical field, more particularly to a kind of LED high-power light-projecting lamps
Phase transformation suppression technology.
Background technology
Existing LED high-power light-projecting lamps radiating mainly has following several：Die casting aluminium nature heat loss through conduction, Copper-Aluminum compound dissipate
Heat.Die casting aluminium radiating rate is slower, and using junction temperature of chip can be caused higher on more than 200W Projecting Lamp, light source life drops
Low, Copper-Aluminum compound radiating uses two kinds of different materials, and thermal coefficient of expansion is different, and outdoor temperature Change is larger, use environment
Badly, two kinds of different materials pass through cold and hot change, it may appear that with reference to not tight, do not cause heat dispersion straight line to decline.
Because more than 200W LED chip caloric value is larger, therefore it is direct with light source heating surface to be typically chosen copper pipe filing
The mode of contact, as power increases, heat pipe increasing number, but inside phase-changeable gas retard motion during heat pipe bending, cause
Heat-transfer rate declines, and when power is more than 500W, simple heat pipe is difficult to meet thermal transmission requirement, it is necessary to using copper base,
The copper processing of same volume is ten times of same volume aluminium, and light fixture radiating cost is too high, it is difficult to practical application.
The content of the invention
Weak point present in regarding to the issue above, the present invention provide a kind of phase transformation of LED high-power light-projecting lamps and suppressed
Technology, use it and special working medium is added inside 1060 aluminium sheets, can not be limited by aluminium sheet shape, ensured in all directions
Heat-transfer rate is consistent, and thermal conductivity is more than four times of copper.
In order to solve the above problems, the present invention provides a kind of phase transformation suppression technology of LED high-power light-projecting lamps, wherein, bag
Include following steps：
S10, using special working medium is added inside 1060 aluminium sheets, product is not limited by aluminium sheet shape, and
Ensure that heat-transfer rate is consistent in all directions；
S20, product are designed as the aluminium sheet structure of global formation with the part of light source contacts；
S30, the side wall of product have been installed in addition with heat pipe and aluminium fin carries out auxiliary heat dissipation, the center installation water proof and dust proof of aluminium fin
Fan is controlled by heat sensor, to adapt to varying environment.
Preferably, the phase transformation of phase transformation suppression technology core suppresses heat sink, by making phase transformation suppress heat sink after adjustment
Effective area of dissipation is more than 20 times of copper pipe, and contact area is two times of copper pipe.
Preferably, the cold-starting that phase transformation suppresses radiating work is -40 DEG C, even under extreme climate, radiator is still
It is able to can be ensured under the environment temperature more than 70 ° with normal work, the heat sensor of installation and supporting water proof and dust proof fan,
Noon still can normally ensure heat dispersion, and heat dispersion can at most lift 50% during starting fan.
Compared with prior art, the present invention has advantages below：
The present invention can not be limited, in all directions using special working medium is added inside 1060 aluminium sheets by aluminium sheet shape
Upper guarantee heat-transfer rate is consistent, and thermal conductivity is more than four times of copper, and the part with light source contacts is the aluminium sheet of global formation, is compared
In traditional heat pipe insertion aluminum plate type installation, water proof and dust proof performance is more preferable, and will not because of two kinds of materials thermal coefficient of expansion not
With there is gap, long lifespan, effective area of dissipation of the phase transformation suppression heat sink of core is more than 20 times of copper pipe, contact surface
Product is two times of copper pipe, has greatly accelerated the export speed of heat at light source.
