Abstract
The utility model discloses a radiator for an LED (light-emitting diode) street lamp. The radiator comprises a radiator base plate; one side of the base plate is integrally provided with a plurality of upwards extending cooling fins, and the other side of the base plate is an LED luminous chip mounting face; two side faces of each cooling fin are integrally provided with a plurality of cooling ribs; the base plate body between two cooling fins is provided with an inverted T-shaped groove used for cooling; two sides of the base plate are respectively provided with a mounting plate parallel to the cooling fins; one end of each mounting plate is provided with a cooling fan capable of blowing air to gaps among the cooling fins. Two sides of each cooling fin are provided with a plurality of cooling ribs at intervals, heat on the base plate of the radiator is transferred from the cooling fins to the cooling ribs, heat is dissipated through the cooling ribs, and the heat dissipation area is greatly increased; the fan is adopted for blowing on the side face, the heat cannot stay, and the heat dissipation effect is better.
Description
Technical field
The utility model relates to heat abstractor, particularly a kind of LED street lamp heat radiator.
Background technology
At present, large power road lamp extensive use, existing large power road lamp also can produce a large amount of heat luminous in shinny, makes the heating of connector high temperature, causes greatly shorten the service life of connector, affects the normal use of large power road lamp.
Existing large power road lamp all can fill a radiator on LED lamp plate, be used for strengthening its life-span, as shown in existing large power road lamp radiator (as Fig. 1), this kind of radiator comprises a foot of radiator 1, one side of foot of radiator 1 is provided with radiator 2, the another side of radiator mount pad 1 is provided with great power LED lamp chip 3, in radiator 2, be interval with some blocks of heat sinks 4, the upper end of radiator 2 arranges radiator fan 5, this kind of large power road lamp radiator is when heat radiation, the wind direction of fan 5 is toward blowing down, cause hot blast to stop, the area of dissipation of heat sink 4 is smaller, radiating effect is not good, cause the service life of LED lamp short.
Utility model content
The purpose of this utility model is the above-mentioned defect for prior art, and a kind of simple in structure, good heat dissipation effect is provided, the LED street lamp heat radiator of long service life.
For solving the above-mentioned defect of prior art, technical scheme to be solved in the utility model is: a kind of LED street lamp heat radiator, comprise a base plate of radiator, the one-body molded fin that has multi-disc to protrude upward of one side of base plate, the another side of described base plate is LED luminescence chip installed surface, also one-body molded in the two sides of fin every described have many heat radiation ribs, on the base plate body between two described fin, have the inverted T shape groove for dispelling the heat, in the both sides of described base plate, be respectively provided with an installing plate paralleling with described multi-disc fin, the radiator fan that can blow facing to the gap between multi-disc fin described in multi-disc is housed in one end of described installing plate.
As a kind of improvement of the utility model LED street lamp heat radiator, the clearance distance between every two described fin is selected in following scope: 5mm～10mm.
As a kind of improvement of the utility model LED street lamp heat radiator, the cross section of described heat radiation rib is triangular in shape.
As a kind of improvement of the utility model LED street lamp heat radiator, the heat radiation rib on every two described fin opposite faces shifts to install.
Compared with prior art, the utility model has the advantages that: the utility model arranges some heat radiation ribs at the equal interval, both sides of fin, heat on base plate of radiator plate is diffused on heat radiation rib by fin, by heat radiation rib, dispel the heat, greatly increased the diffusion area of heat, and adopt blower fan to blow from the side, can not allow heat stop, better heat-radiation effect.
Accompanying drawing explanation
Fig. 1 is prior art structural representation.
Wherein: 1, foot of radiator 2, radiator 3, LED lamp chip 4, heat sink 5, fan.
Fig. 2 is the utility model structural representation.

The specific embodiment
Below just with reference to the accompanying drawings the utility model is further described.
As shown in Figures 2 and 3, a kind of LED street lamp heat radiator, comprise a base plate of radiator 1, the one-body molded fin 2 that has multi-disc to protrude upward of one side of base plate 1, the another side of base plate 1 is LED luminescence chip installed surface 3, also one-body molded in the two sides of fin every described 2 have many heat radiation ribs 4, on base plate 1 body between two fin 2, have the inverted T shape groove 5 for dispelling the heat, in the both sides of base plate 1, be respectively provided with an installing plate 6 paralleling with multi-disc fin 2, the radiator fan 7 that can blow facing to the gap between multi-disc multi-disc fin 2 is housed in one end of installing plate 6.
Preferably, the clearance distance between every two described fin 2 is selected in following scope: 5mm～10mm.The large I of distance in gap is determined according to the size of radiator, the heat radiation of the high-power LED street lamp of applicable various different sizes.
Preferably, the cross section of heat radiation rib 4 is triangular in shape.Heat radiation rib 4 triangular in shape is conducive to the diffusion of heat, and makes simply, saves material.
Preferably, the heat radiation rib 4 on every two fin 2 opposite faces shifts to install.Being conducive to heat up spreads.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.In addition,, although used some specific terms in this description, these terms just for convenience of description, do not form any restriction to the utility model.
