Technical field
The utility model belongs to the radiator structure technical field of LED street lamp, specifically relates to the radiator structure of a kind of 100W and above power LED street lamp.
Background technology
LED street lamp has the superior function of energy-saving and emission-reduction, is the desirable light fixture replacing traditional lighting street lamp.But the heat dissipation problem of 100W and above large power road lamp is the key link that this light fixture of restriction is applied further always.
Traditional aluminium radiator fin formula heat abstractor, its structure as shown in Figure 1, is mainly equipped with the radiating fin of some on aluminum cooling substrates, the heat that LED lamp bead produces can be conducted in air via aluminium flake.But this radiating mode speed is comparatively slow, and conduct in air only for the heat of aluminium sheet upper surface, radiating effect is not good.
Regarding assay test shows: when the PN junction temperature of LED lamp bead reaches 80 DEG C, its life-span will reduce 2/3, and high temperature can accelerate the aging of LED lamp bead fluorescent material and encapsulating material, reduces luminous efficiency, even causes LED structure to damage.Special at the night in scorching summer, environment temperature can reach more than 30 DEG C, pushes away the temperature rise of the LED that risen further.In order to play the advantage of LED street lamp and realize the object of energy-saving and emission-reduction, the heat dispersion improving LED street lamp is a vital task of high-power LED street lamp heat dissipation design.But current heat dissipation design does not take into full account the free convection of LED street lamp and the integrated application of heat pipe.
Utility model content
The purpose of this utility model is the radiator structure providing a kind of 100W and above power LED street lamp, has taken into full account the advantage of free convection and heat pipe heat radiation, has improve the heat dispersion of LED street lamp to greatest extent, effectively reduced the temperature rise of LED street lamp.
For achieving the above object, the utility model have employed following technical scheme:
The radiator structure of a kind of 100W and above power LED street lamp, comprise aluminium base and radiating fin, the lower surface of aluminium base offers arranges the LED lamp bead groove be arranged in parallel more, aluminium base is provided with row's louvre between two row's LED lamp bead grooves, radiating fin is arranged in the both sides of often arranging louvre, on aluminium base with LED lamp bead groove back to position be furnished with the heat radiation heat pipe be placed between two row's radiating fins, bottom and the aluminium base of heat radiation heat pipe fit tightly, and the top of heat radiation heat pipe exceeds the top of radiating fin.
Described heat radiation heat pipe takes the shape of the letter U, and its bottom surface is bonding by the grease of silicone fluid that dispels the heat with aluminium base, and its end, two ends is connected with fin.
The middle part of described fin is placed on the end of heat radiation heat pipe, and it has four radiating surfaces, and each radiating surface is furnished with fin, and the groove between adjacent fin is arranged above and below.
Spacing between the bottom of described fin and aluminium base is not less than the height of radiating fin.
The width of described heat radiation heat pipe is less than the spacing between adjacent heat radiation fin, and heat radiation heat pipe bottom is compressed by the metal derby that spacing between width with adjacent heat radiation fin is equal, and both sides and the radiating fin of metal derby push against.
Compared with prior art, the beneficial effects of the utility model are as follows:
Take full advantage of the two-fold advantage of free convection and heat pipe heat radiation, achieve the free convection of the upper and lower superficial air of LED street lamp, accelerate radiating rate, compare with only there being the radiator structure of aluminium radiating fin, the utility model effectively reduces the temperature rise of LED street lamp, improve the heat dispersion of LED street lamp to greatest extent, improve the service life of LED street lamp and luminous stability, and be easy to safeguard.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
The radiator structure of a kind of 100W shown in Fig. 2-6 and above power LED street lamp, comprise aluminium base 11 and radiating fin 12, the lower surface of aluminium base 11 offers the LED lamp bead groove 13 (for mounted LED lamp bulb) arranged more and be arranged in parallel, aluminium base 11 is provided with row's louvre 14 between two row's LED lamp bead grooves 13, and radiating fin 12 is arranged in the both sides of often arranging louvre 14.I.e. louvre 14 and LED lamp bead groove 13 interleave arrangement, louvre 14 is slotted eye, arranges rational interval between holes.
On aluminium base 11 with LED lamp bead groove 13 back to position be furnished with the heat radiation heat pipe 21 be placed between two row's radiating fins 12, bottom and the aluminium base 11 of heat radiation heat pipe 21 fit tightly heat pipe, fully can absorb the heat that aluminium base conducts.
Described heat radiation heat pipe 21 takes the shape of the letter U, and its bottom surface is bonding by the grease of silicone fluid that dispels the heat with aluminium base 11, and its end, two ends is connected with fin 23.The middle part of described fin 23 is placed on the end of heat radiation heat pipe 21, and it has four radiating surfaces, and each radiating surface is furnished with fin, and the groove between adjacent fin is arranged above and below.Fin increases the area of dissipation of heat radiation heat pipe, is conducive to the convection current up and down of air.
The width of described heat radiation heat pipe 21 is less than the spacing between adjacent heat radiation fin 12, and heat radiation heat pipe 21 bottom is compressed by the metal derby 22 that spacing between width with adjacent heat radiation fin 12 is equal, and both sides and the radiating fin 12 of metal derby 22 push against.Fixing heat pipe that like this can be convenient, flexible, the replacing being convenient to heat pipe is safeguarded.
Radiating fin 12 is distribution in circular arc, and centre is higher, and both sides are lowered gradually, has certain interval between adjacent heat radiation fin 12.Spacing between the bottom of described fin 23 and aluminium base 11 is not less than the height of radiating fin 12.
Above embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
