Description

A kind of radiator applied to lamps and lanterns

Technical field

The utility model relates to field of light fittings, especially a kind of radiator applied to lamps and lanterns.

Background technique

It is well known that since LED light source has many advantages, such as that long service life, low energy consumption, brightness is high and blueness by people It looks at.Therefore more and more lamps and lanterns use LED light source as illuminating source on the market.

But LED light source can generate a large amount of heat in electrified light emitting, if extraneous ring cannot be distributed heat in time In border, LED light source is easy to happen light decay, can also damage when serious, and therefore, existing lamps and lanterns are generally provided with for LED The radiator of light source heat radiation.

Existing radiator includes usually a substrate, and fin of the multi-disc for increasing heat radiation area is provided on substrate, To substrate, the fin that substrate passes through thereon again is distributed into external environment the heat transfer that LED light source generates when being powered.

Although above-mentioned radiator can satisfy general cooling requirements, but the fin on existing radiator is generally done At linear type plate, if air is flowed along the direction on the surface for being parallel to fin, air can pass through radiator, if air Along the direction flowing perpendicular to fin surface, then air will receive the blocking of fin, can not pass through entire radiator, then cause Air cannot take away rapidly the heat on radiator, affect the heat dissipation effect of those radiators.

Utility model content

To solve the above-mentioned problems, the purpose of this utility model is to provide a kind of structure is simple, lamp can either be applied to Tool, while the radiator flowed through convenient for air.

The utility model be solve its technical problem and the technical solution adopted is that:

A kind of radiator applied to lamps and lanterns, comprising:

Substrate；

Multi-disc fin, the fin are set on the substrate；

At least one gas channel excessively that the other side is extended to by the side of substrate is capable of forming between multi-disc fin,

And/or be capable of forming at least one between multi-disc fin and cross gas channel along what the diagonal of substrate extended,

Wherein, the cross sectional shape of the fin is substantially S-shaped.

As an improvement of the above technical solution, multi-disc fin is arranged in several groups fins group, and several groups fins group interval is equal It is set on the substrate evenly.

As a further improvement of the above technical scheme, the spacing phase between two panels fin adjacent in the fins group Deng.

As a preferred embodiment of the utility model, offered on the substrate multiple logical for installing fixed installation Hole.

The beneficial effects of the utility model are: since the radiator of the utility model on substrate by being provided with multi-disc fin Piece is capable of forming at least one between multi-disc fin and crosses gas channel and/or multi-disc fin by what the side of substrate extended to the other side It is capable of forming at least one between piece and crosses gas channel along what the diagonal of substrate extended, wherein the section of the fin Shape is substantially S-shaped, and by using above-mentioned structure, no matter air is flowed from which direction, and air all can be along the fin Surface flow entered gas channel, and then air can quickly flow through the radiator of the utility model and take away radiator On heat, therefore the radiator windage of the utility model is small, ventilation effect is good, and then greatly increases the utility model The radiating efficiency of radiator.

Detailed description of the invention

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.

Fig. 1 is the surface structure schematic diagram of one preferred embodiment of the utility model；

Fig. 2 is the top view of one preferred embodiment of the utility model；

Fig. 3 is use state diagram when being applied on lamps and lanterns in one preferred embodiment of the utility model.

Specific embodiment

Referring to figs. 1 to Fig. 3, a kind of radiator applied to lamps and lanterns, including a substrate 10 and multi-disc fin 20, the fin 20 are set on the substrate 10；It herein, being capable of shape between multi-disc fin 20 as a preferred embodiment of the utility model Crossing between gas channel 30 and/or multi-disc fin 20 for the other side is extended to by the side of substrate 10 at least one to be capable of forming At least one crosses gas channel 30 along what the diagonal of substrate 10 extended, wherein the cross sectional shape of the fin 20 is substantially It is S-shaped.Herein, as a preferred embodiment of the utility model, formed between multi-disc fin 20 it is a plurality of can be by substrate 10 Side extend to the other side cross between gas channel 30 and/or multi-disc fin 20 formed it is a plurality of can be along pair of substrate 10 What linea angulata direction extended crosses gas channel 30.

Radiator due to the utility model by being provided with multi-disc fin 20, energy between multi-disc fin 20 on the substrate 10 Enough formed at least one crossing for the other side is extended to by the side of substrate 10 can between gas channel 30 and/or multi-disc fin 20 It forms at least one and crosses gas channel 30 along what the diagonal of substrate 10 extended, wherein the cross sectional shape of the fin 20 Substantially S-shaped, by using above-mentioned structure, no matter air is flowed from which direction, and air all can be along the fin 20 Surface flow entered in gas channel 30, and then air can quickly flow through dissipating for the utility model along gas channel 30 is crossed Hot device simultaneously takes away the heat on radiator, and then greatly increases the radiating efficiency of the radiator of the utility model.

Wherein, it is manufactured for the ease of the radiator of the utility model, herein, it is preferable that multi-disc fin 20 arranges At several groups fins group, several groups fins group is set to evenly and at intervals on the substrate 10.Further preferably, the fins group In spacing between adjacent two panels fin it is equal.By using above-mentioned structure, both opened convenient for the radiator of the utility model Molding is made, while guaranteeing that adjacent fin 20 will not be overlapped and fitting together, and increases the heat dissipation area of radiator.

Herein, it is installed on lamps and lanterns for the ease of the radiator of the utility model, it is preferable that opened up on the substrate 10 Have multiple for installing fixed installation through-hole 11, therefore bolt can be used across the installation through-hole 11 with by the utility model Radiator be locked on lamps and lanterns, it is simple and convenient.
