Description
Technical field
The invention belongs to radiator field, in particular it relates to a kind of LED chiller with stack effect.
Background technology
Along with the development of science and technology, LED relies on the high and low power consumption of luminous efficiency, is not required to high pressure, safety advantages of higher,
It is widely used at various lighting fields, but (such as headlight, street lamp, Tunnel Lamp, wide when for some big area illuminations
Field illumination, industrial light, garden lamp etc.), at this moment the power of LED is relatively big, and the life-span of LED light source has with the operating temperature of node
Closer contact, current LED in the course of the work only 15%～25% electric energy be converted into luminous energy, remaining electric energy
Nearly all change into heat energy, make the temperature of LED raise, and temperature often increases by 10 degree of its reliabilities and will reduce half.Exist especially
In great power LED, heat radiation is a big problem.If dispelled the heat, bad meeting directly results in LED quick aging, and stability reduces, simultaneously
Dispel the heat and bad can produce serious light decay and affect the life-span of lamp.
The radiating mode major part employing fan of prior art carries out dispelling the heat and meets the cooling requirements of high-powered LED lamp,
There is obvious technological deficiency in this method: (1), because the basic life-span of LED is 50000 hours, the life-span of fan is very
Difficult that meet the most long-time needs, once fan cisco unity malfunction, high-powered LED lamp will damage, and arranges fan dress
Put and add the consumption of the energy, cause the waste of the energy；(2) existing heat abstractor uses metal material to make, matter
Amount is big, increases assembly difficulty.
To this, currently mainly there is following patent in China:
Patent publication No.: CN104296106A, discloses a kind of heat dissipation device of LED lamp, including heat transfer silk and conducting strip, described scattered
Thermal is stacked by several heat conductive sheet layer, leaves certain space between adjacent two conducting strips, and described heat transfer silk is successively
Through several conducting strips, the construction for heat radiating device of several conducting strips described composition is cylindrical, and described conducting strip material is
Heat-conducting plastic.The present invention provides a kind of good heat dissipation effect, safe and reliable LED heat sink for lamp, use heat transfer silk and
Conventional fan heat radiation replaced by conducting strip, solves short problem in fan service life, uses plastic material to carry out heat conduction, solve tradition
The problem that heat abstractor quality is big.But, the conducting strip dense arrangement of this device, it is unfavorable for that air circulates, in actual use
Radiating effect is unsatisfactory.
Summary of the invention
For solving the problem of above-mentioned existence, it is an object of the invention to provide a kind of LED cooling dress with stack effect
Put.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of LED chiller with stack effect,
It is characterized in that, including: radiating seat and LED；Described radiating seat, including: matrix, sleeve and one group of fin；Matrix, for sky
Heart semi-cylindrical shaped；Sleeve, for hollow semi-cylindrical shaped, its bottom surface radius is more than end face radius, is located at outside matrix, its length direction
Consistent with length thereof direction, its axis is consistent with matrix axis；One group of fin, is evenly distributed on the side elevation of matrix, with base
Being arranged radially centered by body, arrange along length thereof direction, described fin extends to intrinsic silicon near one end of matrix,
Fin extends to sleeve medial wall away from one end of matrix.LED, is arranged in described matrix.
Further, described radiating seat is one-body molded.
Separately, described radiating seat is highly consistent with LED.
Separately having, described radiating seat matrix inwall central authorities offer the light trough for mounted LED lamp.
Again, described sleeve lateral surface prolongs vertical direction and is provided with fold.
And, described radiating seat is aluminum alloy material.
Further, described radiating seat sleeve, fin and matrix constitute the gas channel of up/down perforation.
Also, described LED and radiating seat are separable.
Further, described radiating seat base inner surface scribbles reflectorized material.
The beneficial effects of the present invention is: use chimney principle passively to dispel the heat, strengthen channel inner surface cross-ventilation effect,
Can guarantee that radiating effect, save the energy simultaneously, cost-effective.Radiating seat base inner surface scribbles reflectorized material can play convergence
LED light line, improves the effect of brightness.
