The utility model discloses a radiator casing and radiator fin that the disjunctor set up, the radiator fin is the fin monomer of multi -disc along radiator casing length direction interval parallel arrangement, and every fin monomer is arranged with the radiator casing is perpendicular respectively, is equipped with the ripple on every two free cooling surfaces of fin respectively, the length direction who follows the radiator casing in the both sides of radiator casing sets up the recess respectively, and radiator fin both ends are stretched out radiator casing both sides and are arranged formation air guiding gutter, both ends at the radiator casing set up the mounting hole. The utility model has the advantages of simple and reasonable structure, improve the radiating rate, reduced manufacturing cost.
Description
Technical field
This utility model relates to the design field of LED radiator.
Background technology
The module group radiator situation of the high-power road illuminating lamp of current LED is: the pressure-casting type band fin radiating mode that the general high-power road illuminating lamp of LED adopts light fixture to be integrated with heat radiation, although another kind of radiator changes profile-type into, but due to problems such as design and techniques, it is not reaching to desirable radiating effect, some manufacturers are in order to be able to reach radiating effect, do not stint and add large volume and thickness, cause great waste.
It main drawback is that
1) when lamp power is bigger, the radiator of pressure-casting type is also bigger, due to radiator itself is monoblock type, and area is relatively big, and deflection is just big, flatness is poor, contact with the aluminium base being installed with LED lamp bead is just not closely sealed, makes aluminium base closely not fit on radiator, and its heat conductivity is usually no more than 120W/M.K, the temperature on light fixture is made promptly not distribute, and more poly-more high, cause lamp bead light decay to be accelerated, highly shortened the life-span of lamp bead；
2) though some manufacturer also uses profile-type module group radiator, but scientifically not designing heatsink fins plate shape, also adopt common aluminum alloy, heat conductivity does not reach requirement.In order to reach radiating effect, just the volume of radiator and thickness are increased, cause waste.
3) do not take into full account the airflow of radiator, make radiator flow-guiding channel be obstructed, reduce radiating effect, cause heat gathering in LED lamp bead, reduce the normal use time of LED lamp.
Utility model content
This utility model purpose is in that for problem above, it is provided that the radiator being used in the high-power road illuminating lamp of LED of a kind of good heat dissipation effect, raising product quality and reduction cost.
This utility model includes radiator casing and the heat radiator fin that disjunctor is arranged, described heat radiator fin is the multi-disc fin monomer along the spaced and parallel arrangement of radiator casing length direction, described every fin monomer is arranged vertically with radiator casing respectively, is respectively equipped with ripple on two radiating surfaces of every fin monomer；Being respectively provided with groove in the both sides of described radiator casing along the length direction of radiator casing, described heat radiator fin two ends are stretched out radiator casing both sides and are arranged formation air conducting groove；At the two ends of described radiator casing, installing hole is set.
This utility model is simple and reasonable, compared with prior art advantage is in that: 1) adopt highly heat-conductive material 6063-T5, shape makes extrusion molding dies after designing, undertaken being extruded from type by High Temperature High Pressure, its heat conductivity is up to more than 200W/M.K, the thermal source received can be passed to rapidly on radiation tooth, distribute heat in ambient air.2) adopt finned fin, make the surface of ripple glaze on a heat sink, increase the contact surface with air, add radiating rate.3) radiator plane is a part of in the excision of the outside of width with the faying face of aluminium base, its degree of depth arrives radiating fin, radiating fin does not excise, thus at radiator width, air conducting groove occurs, when there being multiple radiator to use side by side, without blocking upper and lower cross-ventilation between two radiators, moreover it is possible to form the convection type of chimney effect formula, heat is taken away as early as possible.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, this utility model includes radiator casing 1 and the heat radiator fin 2 that disjunctor is arranged, described heat radiator fin 2 is the multi-disc fin monomer 2-1 along the radiator casing 1 spaced and parallel arrangement of length direction, described every fin monomer 2-1 is arranged vertically with radiator casing 1 respectively, is respectively equipped with ripple 2-1-1 on two radiating surfaces of every fin monomer 2-1；Being respectively provided with groove 1-1 in the both sides of described radiator casing 1 along the length direction of radiator casing 1, described heat radiator fin 2 two ends are stretched out radiator casing 1 both sides and are arranged formation air conducting groove 4；At the two ends of described radiator casing 1, installing hole 3 is set.
