Abstract

The utility model discloses a composite ceramic heat radiation fin, comprising a heat radiation fin body. The heat radiation fin body is horn-shaped; a groove is arranged at the bottom of the heat radiation fin body; fins are distributed on the outer wall of the heat radiation fin body in a scattering manner; a hollow cavity is arranged inside the heat radiation fin body; an internal thread or a bayonet is arranged at a bottom edge opening of the groove; and an internal thread or a bayonet is arranged at a top opening of the hollow cavity. The composite ceramic heat radiation fin provided by the utility model has the characteristics of simple structure, convenience in operation and maintenance, good heat radiation effect and high practical applicability.

Description

A kind of composite ceramics fin

Technical field

The utility model relates to the fin field, refers more particularly to a kind of composite ceramics fin.

Background technology

In existing resident's family life is incandescent lamp with lamp basically, because incandescent lamp adopts tungsten filament, light efficiency is low, and the life-span is short and not energy-conservation, not environmental protection; And existing LED (light emitting diode) has long, advantages such as light efficiency is high, radiationless, shock resistance and low-power consumption of life-span; Belong to energy-conservation environmental protection illumination; Therefore all used LED in the decorative lightings such as present most indicator lamp and neon light; Adopt led light source to throw light on, can practice thrift a large amount of electric energy; But it is less that the LED technology is used for resident's family life, its reason be its heat dissipation problem difficulty overcome.

The utility model content

The purpose of the utility model is to overcome above-mentioned weak point of the prior art and a kind of simple in structure, easy to operate, novel composite ceramic fin that thermal diffusivity is good, practical is provided.

The utility model is realized through following mode:

A kind of composite ceramics fin comprises heat radiation lamellar body 1, and it is characterized in that: described heat radiation lamellar body 1 is horn-like, and its bottom is provided with groove 4; The outer wall of described heat radiation lamellar body 1 is scatter distributions has fin 5;

Be provided with a hollow cavity 6 in the described heat radiation lamellar body 1; The bottom margin mouth 7 of described groove 4 is provided with internal thread or bayonet socket; The top opening 8 of described hollow cavity 6 is provided with internal thread or bayonet socket.

The advantage of the utility model is: simple in structure, thermal diffusivity good, practical energy-conserving and environment-protective; The ceramic heat-dissipating plate of insulated type high thermal conductivity coefficient; Can directly be installed on LED lamp pearl on the ceramic heat-dissipating plate, the heat that LED lamp pearl produces directly is transmitted in the surrounding environment through the ceramic heat-dissipating plate, and fin increases outer surface heat loss through radiation area; Form the thermal conductance runner between the adjacent fin, being beneficial to heat upwards derives.

The specific embodiment

Combine accompanying drawing at present, the utility model specific embodiment be detailed:

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of composite ceramics fin comprises heat radiation lamellar body 1, and it is characterized in that: described heat radiation lamellar body 1 is horn-like, and its bottom is provided with groove 4; The outer wall of described heat radiation lamellar body 1 is scatter distributions has fin 5;

Heat radiation lamellar body 1 bottom groove 4 of the utility model is the plane, can closely contact with the LED substrate, is beneficial to heat conduction and heat radiation; Heat radiation lamellar body 1 is provided with vertical fin 5, increases outer surface heat loss through radiation area, forms the thermal conductance runner between the adjacent fin, and being beneficial to heat upwards derives; Heat radiation lamellar body 1 inside is set as a hollow cavity 6, and the heat that is used for pedestal is transmitted to the bottom in time is radiated in the cavity; Bottom margin mouth 7 can be provided with internal thread or bayonet socket, is used to connect lampshade; Top opening 8 is provided with internal thread or bayonet socket, is used to connect cap part.
