Description
Technical field
This utility model 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, institute
State heat abstractor to be stacked by several heat conductive sheet layer, between adjacent two conducting strips, leave certain space, described heat transfer silk
Sequentially passing through several conducting strips, the construction for heat radiating device of several conducting strips described composition is cylindrical, described thermally-conductive sheet
Material is heat-conducting plastic.This utility model provides a kind of good heat dissipation effect, safe and reliable LED heat sink for lamp, uses
Conventional fan heat radiation replaced by heat transfer silk and conducting strip, solves short problem in fan service life, uses plastic material to carry out heat conduction,
Solve the problem that traditional heat-dissipating device quality is big.But, the conducting strip dense arrangement of this device, it is unfavorable for that air circulates, in reality
During border uses, radiating effect is unsatisfactory.
Utility model content
For solving the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of LED with stack effect cold
Radiator cooler.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of LED cooling dress with stack effect
Put, it is characterised in that including: radiating seat and LED；Described radiating seat, including: matrix, sleeve and one group of fin；Matrix, for
Hollow 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 side
To 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
Being arranged radially centered by matrix, arrange along length thereof direction, described fin extends in matrix near one end of matrix
Portion, 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 utility model are: use chimney principle passively to dispel the heat, strengthen channel inner surface cross-ventilation
Effect, can guarantee that radiating effect, saves the energy simultaneously, cost-effective.Radiating seat base inner surface scribbles reflectorized material and can play
Converge LED light line, improve the effect of brightness.
