Abstract

The utility model relates to a rolling groove type radiator which solves the technical problems that a radiating structure of the existing light-emitting diode (LED) lamp is poor in radiating performance, luminous efficiency of an LED is reduced and service life is shortened. The rolling groove type radiator is provided with a substrate, an upper cover and cooling fins, wherein the cooling fins are arranged between the substrate and the upper cover and distributed in a radiating shape with centers of the substrate and the upper cover to be the center of a circle, the cooling fins are in laminar shape, heat dissipation holes are formed in the upper cover and placed between the cooling fins in the radial direction, and the rolling groove type radiator can be widely applied to the heat dissipation of the LED lamp.

Description

A kind of pressing groove type radiator

Technical field

The utility model relates to a kind of radiator, particularly relates to a kind of pressing groove type radiator.

Background technology

At present, the LED lamp is widely used in field of illuminating lamps.The LED lamp is when work, and the led chip caloric value is very large; Bad if dispel the heat, can make excess Temperature, cause the reduction of LED luminous efficiency, the lost of life.Along with the high-power LED chip application is more and more, heat dissipation problem becomes the bottleneck that hinders the great power LED development.In order to guarantee the LED normal operation, must take measures, heat is in time distributed.

Summary of the invention

The utility model is exactly that existing LED lamp radiator structure heat dispersion is poor in order to solve, the LED luminous efficiency reduces and the technical problem of the lost of life, provide a kind of can Effective Raise heat dissipation capacity and luminous efficiency and make the pressing groove type radiator that can be used for high-powered LED lamp of life.

The technical solution of the utility model is, a kind of pressing groove type radiator is provided, be provided with pedestal, loam cake and fin, fin is located between pedestal and the loam cake, and radially distribute as the center of circle take the center of pedestal and loam cake, it is laminar, on be covered with louvre, louvre in radial direction between fin.

The preferred technical scheme of the utility model is that pedestal and loam cake are circular, and are respectively equipped with slot; Vertically insert in the slot of pedestal and loam cake respectively at the two ends of fin.

The utility model further preferred technical scheme is, is provided with fixed leg between pedestal and the loam cake, and fixed leg is four, and one of them is positioned on the central axis of pedestal and loam cake, and other three even vertical distribution are on the peripheral circumferential of pedestal; Pedestal and loam cake are by the fixed leg socket connection.

The utility model more further preferred technical scheme is that the slotting poor contact-making surface of fin and pedestal and loam cake is provided with heat-conducting medium.

The utlity model has very high radiating efficiency, can greatly improve heat dissipation capacity, improve the LED luminous efficiency, and prolong the life-span of LED; It is simple in structure, can save material, does not need special processing process and special material, can reduce production costs, and has good economic benefit and social benefit.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Symbol description among the figure:

1. pedestal; 2. fin; 3. loam cake; 4. fixed leg; 5. louvre.

The specific embodiment

Referring to accompanying drawing, with specific embodiment the utility model is described in further detail.

With reference to figure 1, this device is three-dimensional LED radiator, and it is provided with pedestal 1, fin 2 and loam cake 3, and fin 2 is rectangular sheet, and pedestal 1 and loam cake 3 are circular.Be provided with a plurality of slots on the pedestal 1, loam cake 3 also is provided with the slot corresponding with the position of pedestal 1.The slot quantity of pedestal 1 or loam cake 3 is consistent with the quantity of fin 2.Fin 2 one ends insert in the slot of pedestal 1, and the other end of fin 2 inserts in the slot of loam cake 3, and fin 2 and pedestal 1, loam cake 3 are vertical and with the fixed leg 4 emanant distributions at pedestal 1 center.Pedestal 1 passes through four fixed leg 4 socket connections with loam cake 3.Have louvre 5 between the slot of loam cake 3, the quantity of louvre 5 is identical with the quantity of fin 2.

During use, the LED lamp panel is fixed on the bottom surface of pedestal 1, the heat that lamp panel produces is transmitted on the fin 2 by pedestal 1, is transmitted on the loam cake 3 by fin 2 again.The heat that pedestal 1 sheds rises air the air heat in space between the multi-disc fin 2, discharges by the louvre 5 on the loam cake 3, thereby makes Air Flow, plays the effect of heat radiation.

Fin 2 can evenly scribble a certain amount of heat-conducting medium with slotting poor contact-making surface, such as heat-conducting silicone grease or heat-conducting glue, from then making the heat transmission effect better, strengthens its radiating effect.

Said base 1, fin 2, loam cake 3 and fixed leg 4 can be made with the metal materials such as aluminium of good heat conductivity.

The shape of pedestal 1 and loam cake 3 can be other shapes such as square, as long as can satisfy the fixedly matching requirements of LED lamp panel.
