Part producer adopts ceramic heat-dissipating, and pottery is heavier, while ceramic heat-dissipating cost is of a relatively high.
Content of the invention
In order to solve the above problems the invention provides a kind of good heat dissipation effect, lighter weight, while cost is relatively low, can
The LDE lamp radiators for increasing the service life.
In order to reach the problems referred to above, the present invention is achieved through the following technical solutions：
The present invention is a kind of LED lamp heat sink, and including several heat radiator bodies and thermal column, several heat radiator bodies are arranged on thermal column
Outside, each heat radiator body include the substrate that fits with thermal column, substrate side are provided with the slot of protrusion, in the another of substrate
Side is provided with the inserted sheet in the slot on the adjacent substrate of insertion, on the inside of the slot of each substrate upper end is provided with fixed pottery
The interior of porcelain heat sink is buckled, and on ceramic heat-dissipating plate is provided with chute, and substrate upper end is provided with upper sealing plate, and upper sealing plate passes through screw
Be fixed on substrate, the side plate for supporting ceramic heat-dissipating plate is provided with the substrate lower end for being provided with slot-side, in chute lower end
Side plate on be provided with the fixed column of fixed ceramic heat-dissipating plate, substrate lower end is provided with lower shrouding, is provided with the outside of substrate
Several fin.
Further improvement of the present invention is：The interior button front end is provided with notch, is provided with the chute upper end
The casting lug thereon being buckled in the notch.
Further improvement of the present invention is：The substrate, upper sealing plate and the lower shrouding adopt aluminum alloy materials system
Into.
Further improvement of the present invention is：The heat sink both sides are provided with several side fin.
The beneficial effects of the utility model are：The radiator body of the present invention is by several substrates, ceramic heat-dissipating plate and to dissipate
Plume is constituted, and slot and inserted sheet connection of several substrates by protrusion, ceramic heat-dissipating plate are fixed on base by the interior button on slot
On plate, the side plate for supporting ceramic heat-dissipating plate is provided with the substrate lower end for being provided with slot-side, side plate can be played holds pottery
Porcelain heat sink, the gravity for preventing interior button from bearing is excessive to cause interior button flexural deformation, and pottery is dissipated by the fixed column arranged on side plate
