Summary of the invention
Goal of the invention: the object of the invention is in order to solve above the deficiencies in the prior art, a kind of finned LED lamp radiator is provided, can effectively improve the heat radiation of LED lamp, improve the physical life of LED lamp.
Technical scheme: finned LED lamp radiator of the present invention, its objective is such realization, a kind of finned LED lamp radiator, comprise LED luminous plaque, fixing base, radiating fin, one side of described fixing base is provided with LED luminous plaque, the opposite side of described fixing base is provided with radiating fin, the regularly arranged formation concentrated type of some radiating fins radiating fin group.
Described radiating fin and fixing base are arranged vertically, radiating fin is plugged on fixing base, heat on fixing base is directly conducted by radiating fin, and, the even grafting radiating fin in whole of one side of described fixing base, when fixing base heat conductivility is good, heat transmits out by each the piece radiating fin being connected with fixing base.
In described concentrated type radiating fin group, also run through and be provided with heat pipe, described heat pipe is all connected with the every a slice radiating fin in concentrated type radiating fin group, heat between adjacent radiating fin is transmitted mutually, reduce rapidly the heat of high-temperature region, make the heat balance on each fin, and easily volatilization.
Described heat pipe is U-shaped pipe, comprise two long straight pins and the connecting portion that is connected two long straight tube pin, two long straight pins are all through every a slice radiating fin, wherein a pin is used for absorbing and transferring heat near described fixing base, another root pin is away from described fixing base, heat is after fixing base is delivered to radiating fin, can not assemble at radiating fin root, by the pin near fixing base, be delivered to other radiating fin and another pin, allow the heat on radiating fin root conduct rapidly and to distribute, heat on assurance fixing base is derived rapidly.
In described heat pipe, seal and be filled with refrigerating fluid, the internal pressure while sealing by adjusting heat pipe changes the boiling point of refrigerating fluid.
The quantity of described heat pipe is 3, 3 pins near fixing base are equidistantly arranged at the LED luminous plaque back side, and the width of two pins in both sides equals the width of LED luminous plaque, interim pins is over against the center line of LED luminous plaque, because heat is delivered to fixing base from LED luminous plaque, the heat of the fixing base part being connected with LED luminous plaque is maximum, at 3 equally spaced heat pipe pins of this region division, make on the one hand heat be delivered to adjacent radiating fin by pin separately, make on the other hand heat be delivered to another pin away from fixing base that pin is connected separately, and continue to pass to radiating fin away from the part of fixing base, make the heat on fixing base transmit rapidly and distribute, heat on assurance fixing base is derived rapidly.
The material of described fixing base is high thermal conductivity material, as red copper, guarantees that fixing base heat conductivility is good.
Beneficial effect: finned LED lamp radiator of the present invention, by LED luminous plaque being installed on the fixing base of high thermal conductivity material, the heat producing in LED light source work is derived rapidly, by transferring heat to the concentrated type radiating fin group of pegging graft on fixing base, and by heat pipe transferring heat between adjacent radiating fin, and by the large-area heat radiation of radiating fin, can extend the inner heating-up time of LED light source, reduce the inner junction temperature of LED light source, relatively increase light source life.
