Specific embodiment
Term used herein is used only for the purpose of describing specific embodiments, and is not intended to limit the present invention.Unless in addition
Definition, otherwise all terms used herein have normally understood identical with those skilled in the art
Meaning.It will be further appreciated that essential term should be interpreted as having and it is in related fields and present disclosure
The consistent meaning of meaning.The disclosure will be considered as example of the invention, and is not intended to and limits the invention to particular implementation
Example.
Embodiment one
The radiator of a kind of lamps and lanterns as shown in Figure 1, using the passive heat radiation of predominantly outdoor lamp.Heat dissipation dress
Set the array of fins including plate body 1 and annular.Plate body 1 is equipped with for the structure with lamps and lanterns assembly connection, such as screw hole, card
Button etc..The array of fins includes multiple radiating fins 11 for being arranged to edge of centers along annular, adjacent radiating fin 11 it
Between formed for heat dissipation channel 12.The plate body and array of fins of the present embodiment be aluminium or aluminum alloy material, it is light-weight, thermally conductive
Effect is good, is formed using die-casting process, so that product processes are simpler.Radiating fin 11 is the song towards curving
The bending direction of face fin, all radiating fins 11 in array of fins is identical.For example, all radiating fins in array of fins
11 can all be bent with the sun, all can also against the sun be bent.Channel 12 includes close to annular center
The first ventilation opening 121 and the second ventilation opening 122 close to ring edge, and width of the channel 12 close to annular center side is small
In it close to the width of ring edge side.Channel width close to ring edge is larger, facilitates outside air being introduced to channel
It is interior；Air, since channel width becomes narrow gradually air flow faster, can quickly take away heat during flowing along channel
Amount；Heat at annular center is most, and the channel width of channel at this location is also minimum, air at the corresponding position
Flow velocity is maximum, can quickly take away heat.In the present embodiment, the annular array that radiating fin 11 is formed is at the back side of radiator
It is rendered as based on Fibonacci golden spiral curve, so that the width in each channel 12 is gradually become by annular center towards ring edge
Width forms the air convection channel that multiple centers by annular are distributed to ring edge, can be carried out by the convection current of air
Heat dissipation.When radiator be applied to outdoor lamp when, it can be ensured that outdoor lamp outdoors at the time of variation and air flow
In the uncertain situation in direction, it is ensured that always have the direction in a channel not vertical with outdoor air-flow direction, to guarantee
The air flowing fast speed belt of radiator walks heat (as shown in Figure 2).
It only needs when being equipped with the wire connection cavity 2 of indent, light wiring and maintenance at the array of fins center of annular by wire connection cavity 2
Lid open, do not need to disassemble entire radiator so that wiring and safeguard it is more convenient.In wire connection cavity 2
Recessed is arranged at the center of array of fins, will not stop the air circulation in each channel, is more conducive to distributing for heat.In plate
The front (being not provided with the one side of array of fins) of body 1 is equipped with heat-conducting part, when radiator is installed on lamps and lanterns, heat-conducting part
Timely the heat that lamps and lanterns generate can be transmitted on plate body 1 through 11 rapid cooling of radiating fin.Heat-conducting part can be graphite
Heat conductive pad, silicagel pad or the heat-conducting cream being filled between plate body and lamps and lanterns.It is used as and is led using graphite guide heat pad in the present embodiment
Hot portion.
In above-mentioned technical proposal, channel is convenient for the convection current by air to radiate, and improves heat dissipation effect.Radiating fin is in
Annular spread is formed in the channel between adjacent fins accordingly and is also distributed in a ring, can ensure that how no matter wind direction change all
A stable convection channel is had to radiate.
Preferably, the height of the radiating fin being set on plate body 1 in the present embodiment is about 50-65mm best, make
The height for obtaining the channel formed between adjacent radiating fin is about 50-65mm.Preferably, in the present embodiment channel minimum
Width (i.e. close to annular center side the first ventilation opening width) ratio with the height (namely height of radiating fin) in channel
Value is 6.5-9.
When the radiator of the utility model is mounted on the corresponding outdoor lamp back side, can obtain take into account Visual Aesthetics and
The curved-surface structure of good heat dissipation performance.Not only make the lamps and lanterns product appearance visual impression for applying the radiator stronger,
Embody the aesthetics design objective of " beauty of design is derived from naturally, be loyal to nature ".Under identical steric requirements, compared to vertical bar
The cooling surface area of formula cooling fin can increase 5%-10%, and the heat sink design of curve shape keeps hot-air convection channel more suitable
Freely, product thermal diffusivity is promoted.
Although being described in conjunction with the accompanying the embodiments of the present invention, those of ordinary skill in the art can be in institute
Various deformations or amendments are made in attached the scope of the claims.
