Abstract
A radiator used for carrying out heat dissipation of LED modules comprises a heat conductor and a plurality of spaced heat conductive arms protruding from the outer wall of the heat conductor to outside. Each heat conductive arm is provided with a group of radiating fins, and a plane to which the LED modules are adhered is formed on the most lateral radiating fins among each group of radiating fins. The most lateral radiating fins among each group of radiating fins are directly thermally contacted with the LED modules. Therefore, the radiator can simultaneously carry out heat dissipation for a plurality of LED modules on different planes.
Description
Technical field
The present invention relates to a kind of radiator, particularly a kind of radiator that light emitting diode is dispelled the heat.
Background technology
Along with the develop rapidly of electronic industry, the electronic component speed of service constantly promotes, and produces a large amount of heats during operation, and itself and system temperature are raise, and influences the stability of its system then.For guaranteeing that electronic component can normally move, a radiator is installed usually, thereon to discharge the heat that it is produced.
The traditional solution of electronic element radiating problem is normally installed a radiator on each heat-generating electronic elements, this radiator comprises the base plate that closely contacts with electronic component, is located at the some radiating fins on the base plate.But, not on same plate face, so then can't use common radiator it is dispelled the heat for some special heat-generating electronic elements and radiator.
For example, in the less led lamp of some volumes, need come with the radiator that a volume is limited very for a short time relatively simultaneously some light emitting diode module to be dispelled the heat, this be that common radiator can't be accomplished.
Summary of the invention
In view of this, be necessary to provide a kind of radiator that can be simultaneously at grade a plurality of light emitting diode module be not dispelled the heat.
A kind of radiator, being used for light emitting diode module dispels the heat, it comprises that a heat carrier reaches the Thermal Arm from the outward extending some intervals of heat carrier outer wall, be formed with one group of radiating fin on described each Thermal Arm, be formed with a plane that supplies described light emitting diode module to be sticked in described every group of radiating fin on the outermost radiating fin.
Outermost radiating fin directly contacts with luminous thermal diode module in the above-mentioned radiator, and radiator of the present invention thus just can dispel the heat to a plurality of light emitting diode module on Different Plane simultaneously.
With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.
Description of drawings
Fig. 1 is the stereogram of radiator of the present invention.
Fig. 2 is the vertical view of radiator among Fig. 1.
The specific embodiment
Shown in Fig. 1-2, radiator of the present invention is used for light emitting diode module (figure does not show) is dispelled the heat, and it is integrally formed by heat conductivility good material such as metal materials such as aluminium, copper.
This radiator center has a heat carrier, this heat carrier is a heat conduction cylindrical shell 10 cylindraceous in the present embodiment, these heat conduction cylindrical shell 10 inwalls fin 12 in some bar shapeds that extended internally, fins 12 are about these heat conduction cylindrical shell 10 central axis branch symmetrically in these, and they are along the radially extension of this heat conduction cylindrical shell 10, the thickness of fin 12 begins inwardly to diminish gradually from cylinder inboard wall in being somebody's turn to do, and the drift angle tip is passivated shape so its cross section roughly is acute triangle.It radially is extended with some Thermal Arms 14 to this heat conduction cylindrical shell 10 to the outer, these Thermal Arms 14 all distribute symmetrically about these cylindrical shell 10 central axis, and its concrete quantity is six Thermal Arms 14 by the quantity decision of electronic component in the concrete application in the present embodiment.The extended line of these Thermal Arms 14 will intersect at the central axis of this cylindrical shell 10, this Thermal Arm 14 vertically is extended with the some to radiating fin 140 of parallel interval to both sides, each also is distributed in this Thermal Arm 14 both sides to radiating fin 140 symmetrically perpendicular to this Thermal Arm 14, and the length of these radiating fins 140 is increased progressively to the other end away from this cylindrical shell 10 by the end of this Thermal Arm 14 near these cylindrical shells 10.Lean on outermost a pair of radiating fin 140 to be symmetrically distributed in the end of this heat carrier 14, this outer surface to radiating fin 140 forms a smooth surfaces.
In use, each of above-mentioned radiator all contacts with the light emitting diode module of arranging at grade outermost radiating fin 140, and this radiator just can dispel the heat to a plurality of electric component group or electronic component on Different Plane simultaneously like this.
This radiator bottom can directly contact with light emitting diode module or other electron component and to its heat radiation in other embodiments, also the heat carrier at radiator center can be designed to a solid cylinder or a column-type heat tube, the bottom surface of this heat carrier contacts with electronic component again.
