Description
Technical field
The present invention relates to a kind of radiator, particularly a kind of LED lamp heat sink.
Background technology
It is well known that LED can produce substantial amounts of heat at work, in order that obtaining heat caused by LED work
Can promptly it distribute, in general LED can all be equipped with radiator, and present radiator typically uses following structure：
Including one being used for installing the pedestal of LED light source, polylith fin is connected with by multiple heat-conducting pieces on pedestal.When LED light source work
Heat caused by work can be transferred on pedestal, and heat can be rapidly transferred to polylith by multiple heat-conducting pieces and dissipated by pedestal
On backing, promptly it can be transferred heat to finally by the surface of fin in the external world.
Although above-mentioned radiator can also play a part of radiating and cooling, because the fin of radiator is to pass through
Heat-conducting piece is connected and installed on pedestal, therefore in some cases, if heat-conducting piece deforms, can cause polylith fin phase
It is mutually close, or even polylith fin is mutually close together, and not only influences the surface that air flows through fin, and severe decrease
The area of dissipation of radiator, and then had a strong impact on the heat dispersion of radiator so that the heat dispersion of radiator is unstable.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide a kind of simple in construction, while fin will not be mutual
Radiator that is close or being close together.
The present invention is for the technical scheme that uses of its technical problem of solution：
A kind of LED lamp heat sink, including one be used to install the pedestal of light source, and multiple heat-conducting pieces are provided with the pedestal,
The profile of the heat-conducting piece takes the shape of the letter U and is respectively arranged with a fin, multiple heat-conducting piece intervals in two U-shaped arms of the heat-conducting piece
Form a line and so that the fin in two U-shaped arms of those heat-conducting pieces, which is also respectively separated, is arranged in two row groups of fins, together
When two row groups of fins on be respectively arranged with the changeless fixing device of spacing kept between adjacent two fin.
As the improvement of above-mentioned technical proposal, the fixing device is a long bolt, and energy is offered on each fin
Enough screwed holes being used in combination with the long bolt.
As the further improvement of above-mentioned technical proposal, the fixing device is a strip that can pass through multiple fin
Rod member, multiple distance pieces between two adjacent fin respectively are arranged with the strip rod member, the distance piece
Both ends fin adjacent thereto can abut against respectively, and being offered on the fin can allow what the strip rod member passed through
Through hole.
In the present invention, the pedestal is also fixedly connected with one and enclosed in the fixed frame of multiple fin peripheries, described
Fixing device is fixedly arranged on the fixed frame.
Preferably, a handle is also hinged with the fixed frame.
Further, also at least provided with a heat superconducting that can be in contact with multiple heat-conducting pieces simultaneously on the pedestal
Pipe, the super heat-conductive pipe are also in contact with pedestal simultaneously.
Further, the length direction of the super heat-conductive pipe be arranged in multiple heat-conducting pieces a row direction it is identical.
In the present invention, the super heat-conductive pipe is arranged at the side that heat-conducting piece deviates from the pedestal.
Preferably, two super heat-conductive pipes are provided with the pedestal.
The beneficial effects of the invention are as follows：Because the radiator of the present invention is by the way that multiple heat-conducting pieces are formed a line and more
Fin in two U-shaped arms of individual heat-conducting piece is arranged together in two row groups of fins, while using fixing device respectively by two
Spacing locking in row groups of fins between two adjacent fin so that adjacent fin will not be close to each other or is close to
Together, ensure that the spacing between abutting fins immobilizes, therefore heat can be preferably from the scattered of two row groups of fins
It is dispersed on backing in external environment, and then greatly improves the heat dispersion of the radiator of the present invention.
