Due to saving the advantage with environmental protection, LED is considered as mankind's lighting engineering of future generation.But due to expensive cost,
And reliability is low, LED illumination popularization and application is hampered.Caused by the high and insecure main cause of valency is LED heat dissipation problems.
LED exothermic temperatures are not high, less than 100 DEG C, thus its radiating mainly by convection heat transfer' heat-transfer by convection, radiant heat transfer proportion is non-
It is often small.Convection heat transfer' heat-transfer by convection process is finally that air flow takes away heat, hereby it is ensured that air flow is unimpeded extremely important, particularly
Free convection heat transfer (heat dissipating method that LED is used), but the general principle, are not paid attention to by LED illumination industry.
Sun fancy fin (structure that fin stretches out from heating column side), (can be used aluminum extruded due to easy to manufacture
Technique is manufactured), it is widely used.When fin axis is erect and set, free convection air is from bottom to top along fin surface
Flowing, air circulation is good, and heat dispersion is optimal.But when the axial level of fin is horizontal, radiating air is difficult to flow through fin
, there are many air flow dead bands in surface, circulation is poor, thus heat dispersion is decreased obviously.Existing disclosed product and technology, do not have
There is the scheme for being shown to solve the problem.

The air-flow trough depth c shown is more than the long l of 1/2nd ribs above described, during design, and air-flow trough should be as deep as possible, favorably
When horizontal, radiating air runs through fin, preferably chooses rib long ls of the air-flow trough depth c more than 2/3rds.It is circle for profile
Shape, heating column are also circular sun fancy fin, and rib length is exactly that the profile diameter of fin subtracts heat conduction column diameter naturally, then is removed
2, i.e. l=0.5 × (D-d).If external form of cooling fin and heating column are not circular, D and d value are working as by areal calculation
Diameter is measured, such as external form of cooling fin is 40 × 40mm rectangles, and area equivalent diameter can be calculated as
Natural Heat Convection, it is the buoyancy that air is heated up and produced to drive cross-ventilated power, and driving force is limited.It is logical
Encryption fin is crossed, increases area of dissipation, is improved the factor of heat dissipation capacity, but also there are negative factor：The increase of fin density, stream
Dynamic resistance increase, causes radiating air to reduce, and is the factor that heat dispersion declines.Thus fin density should not be too close, there is one
The maximum optimal value of heat dissipation capacity, can be obtained by lot of experimental data analysis, during deisgn product, take fin rib it is high with fin it
Between the ratio between gap be that, more than 2, less than 8, when fin fin gap is uneven, average gap should be taken, when rib is high uneven
Average height should be taken.It should be noted that the high value of rib should be the actual height of axis direction fin, and exemplified by shown in Fig. 4, rib Gao Buying
It is H, but H subtracts 2 wide a of air-flow trough, that is, the three short high h sums of rib.
