Description
Technical field
This utility model is related to a kind of radiator of Down lamp.
Background technology
Heat dissipation problem is considered as the big technical barrier in LED illumination lamp, and the structural cost of radiating also account for
The considerable part of LED lamp cost, has radiated into the Radix Clematidis Clarkeanae on LED illumination lamp widespread development road.
However, most LED photovoltaic illuminating products fail using thermaltransmission mode, as shown in the accompanying drawings 1 very well
Structure, radiator is simply to set some radiating fins to increase area of dissipation, in the hope of being radiated.
It will be apparent that prior art lacks the accurate understanding of natural convection air heat dissipation technology and illuminating product moulding or knot
The naturally cleverly associativity practice of structure design, lead to most LED photovoltaic illuminating products be difficult to make high-power come, otherwise can
Bear larger radiator structure cost, or even heavy or super-large dimension product-forming occurs.
Therefore, there is improvement necessity in existing structure.
Content of the invention
The purpose of this utility model is to provide a kind of radiating effect good radiator.
For achieving the above object, this utility model employs the following technical solutions：
A kind of radiator of Down lamp, including a substrate, the first face of substrate is provided with the installation portion installed for luminescence unit,
The central area position of the corresponding described installation portion in the second face of described substrate is convexly equipped with thermal column body, and the second face of described substrate is also
It is provided with some first radiating fins, each first radiating fin outwards dissipates distribution from centered on described radiating cylinder, the first radiating
Form the air flow channel radially circulating along institute's radiator between fin and the first radiating fin.
This utility model can be improved by following scheme：
The side of described radiating cylinder is convexly equipped with some flanks.
The thickness of described flank is outwards gradually thinning from center.
Projection has three flanks in the side of described radiating cylinder, the midplane of each flank and described first radiating fin its
In the midplane of three be in same plane.
Second face of described substrate is additionally provided with some second radiating fins, and each second radiating fin from described radiating cylinder is
Center outwards dissipates distribution and is respectively in formed air flow channel between the first radiating fin and the first radiating fin.
Each first radiating fin and each second radiating fin diametrically have the nearer end at close radiator center and remote
The relatively far-end at discrete heat device center, the relatively far-end of each first radiating fin and each second radiating fin is in and with radiator center is
On the same circumference in the center of circle, the nearer end of more each second radiating fin of nearer end of each first radiating fin is in radiator
The heart.
Each second radiating fin is provided with guiding cambered surface on the side wall of nearer end.
The radiator advantage of Down lamp of the present utility model is good heat dissipation effect.

Specific embodiment
As shown in Figures 3 to 5, radiator 1 includes a substrate 2, and the first face of substrate 2 is provided with for luminescence unit peace
The installation portion of dress, the central area position of the corresponding described installation portion in the second face of described substrate 2 is convexly equipped with thermal column body 3, described
Second face of substrate 2 is additionally provided with some first radiating fins 4, and each first radiating fin 4 is outside from centered on described radiating cylinder 3
Dissipate distribution, between the first radiating fin 4 and the first radiating fin 4, form the air flow channel 7 radially circulating along institute's radiator 1.
The side of described radiating cylinder 3 is convexly equipped with some flanks 31.The thickness of described flank 31 outwards gradually becomes from center
Thin.Specifically projection has three flanks 31 in the side of described radiating cylinder 3, and the midplane of each flank 31 dissipates with described first
The midplane of hot fin 4 wherein three is in same plane（Can be seen that from accompanying drawing 5, i.e. each flank 31 and the first radiating fin 4
Wherein three be in described substrate 2 same in the radial direction）.
In order to strengthen cross-ventilation effect, the second face of described substrate 2 is additionally provided with some second radiating fins 5, and each second
Radiating fin 5 outwards dissipates distribution from centered on described radiating cylinder 3 and is respectively in the first radiating fin 4 and the first radiating fin
In formed air flow channel 7 between 4.
Each first radiating fin 4 and each second radiating fin 5 diametrically have close radiator 1 center nearer end and
Away from the relatively far-end at radiator 1 center, the relatively far-end of each first radiating fin 4 and each second radiating fin 5 is in radiator 1
Center is on the same circumference in the center of circle, and the nearer end of more each second radiating fin 5 of nearer end of each first radiating fin 4 is near scattered
Hot device 1 center.
In addition, each second radiating fin 5 is provided with guiding cambered surface 51 to carry out water conservancy diversion to air on the side wall of nearer end
Effect.
Radiator 1 is integrally formed by extrusion process.
As shown in Figure 2, when radiator 1 is assembled into Down lamp, the lampshade of Down lamp is connected with radiator 1, the luminous list of Down lamp
Unit can be directly mounted on the installation portion of radiator 1, and during use, heat produced by luminescence unit first passes through the base of radiator 1
Plate 2 is transmitted to radiating cylinder 3, and air takes away, in the flowing of air flow channel 7, the heat being transmitted to radiating cylinder 3, thus realizing
Preferably radiating effect.
