Description
Technical field
The present invention relates to LED lamp illumination module, be specifically related to a kind of dam LED illumination module of powder for lowering blood pressure heat structure of capillary that has.
Background technology
Because during LED lamp engine work operation, direct current produces junction temperature Tj through semiconductor wafer, junction temperature more greatly then light decay is serious more, causes influencing semiconductor (LED) performance and life-span.Press LED heat radiation formula:
Tj(℃)＝Ric×VF×IF+Tc
RBA(℃/W)＝(Tc-Ta)÷(VF×IF)
RJA＝RJC+RBA
Can know by above-mentioned formula, improve the LED working life, reduce light decay; Remove the electric current and voltage of selecting coupling, lower the RJA coefficient relatively, the RBA coefficient; Main is to promote heat radiation conduction pattern and the speed of improving Tc; Hot-side temperature is comparatively fast reduced, reduce temperature and hoard, could improve luminous benefit and stability.
At present, the LED lighting device generally adopts the aluminium section heat radiation on the market, because of its thermal resistance is bigger, can not satisfy the great power LED cooling condition.The radiator structure of hot pipe technique adopts sealing in the superconductive medium pipe like (patent No. 200810065846.8), and the technology mode that runs through radiating fin is better, and conduction of velocity is very fast.But hot-fluid is bigger, and the individual plant radiating tube will satisfy great power LED cooling need be increased the large tracts of land radiating fin and could realize with longer heat pipe coupling.It adopts the solid dielectric perfusion, can't hold single many strains of chamber tap hole pipe instillation process.If adopt the liquid agent perfusion, then this device can't the application of heat pipe backflow functionality.
Like (patent No. 200910077583.7) a kind of radiator structure, the limitation that its structure and operation principle also exist overall volume and heat-transfer rate and working medium to reflux.Present stage adopts the heat sink material of copper aluminium welding to receive much attention, and utilizes material behavior to improve the heat-transfer rate and the specific heat load of radiating piece on the essential meaning.
Solving heat dissipation problem has become the prerequisite of LED Lighting Industryization, and the phase transformation cooling technology possibly be the main direction that improves heat flow density cooling development, and heat pipe is to utilize phase transformation to come the enhanced heat exchange major technology.And effect capillaceous is the step-down of damming, and the liquid agent of the HTHP that can send here in the heating chamber discharges its pressure, makes it become the liquid agent of low-temp low-pressure.
By formula; Heat flow density (q)=hot-fluid J/S sectional area
Q=Q/S*t (heat flux=heat/sectional area * time)
The relation of heat flow density and thermal conductivity factor,
Material heat flow density
material thermal conductivity * (hot-surface temperature-cold surface temperature)/material thickness.Heat flow density is to investigate the important indicator of equipment cooling performance.
Public reported and Related product that domestic and international relevant heat pipe heat radiation is applied to the great power LED cooling are limited to by radiating rate and device volume still, also can not apply fully.
Along with international community promotes the notion of the green earth, department of national governments reduces discharging energy-conservation, and the consciousness of low-carbon (LC) is strengthened day by day, and especially the LED illumination is more outstanding, so be badly in need of solving bottleneck problem one heat radiation in the existing LED Lighting Industry on the market.The invention provides a kind of employing capillary buck configuration of damming, dwindle the hot-fluid ratio, reduce thermal resistance; Strengthen the heat exchange efficiency and adopt the fin that has window to be close to capillary wall; The length of bending lamination expansion sheet number, quantity increases cooling surface area and cross-ventilation intensity; Characteristics such as it is high to have the heat exchange efficiency, and radiating rate is very fast.With the patent No. of I invent multi is that the high-power LED illuminator of the cooled by finned tubular radiator of ZL201120048778.1 (utility model mandate) is compared; Not only significantly dwindle small product size in the use; And obtained more powerful radiating effect, the heat exchange Energy Efficiency Ratio is remarkable.
