Description
Technical field
The utility model relates to radiator structure, especially a kind of LED lamp and radiator structure thereof.
Background technology
Existing LED illuminating lamp because heating is very big at work, if heat in time is not dispersed into the external world, will cause the led chip temperature to raise, and at high temperature work, often chip failure.For increasing the reliability of work, design radiator to chip cooling.The radiator of existing LED lamp, for improving radiating effect, the radiating mode of employing mainly contains three kinds, and a kind of is the surface radiating that utilizes lamp outer casing, a kind of heat pipe heat radiation that is to use, also having a kind of is the fan heat radiation.Utilize the outer surface heat radiation of lamp outer casing, because the good material conduction of heat conduction is also strong, extraneous induced electricity etc. is easy to have influence on the operate as normal of chip, and shell also was easy to chargedly when chip punctured, and produced potential safety hazard.Utilize the mode of heat pipe heat radiation, because the main practical metal material of heat sink material, insulating properties can not get ensureing.Adopt fan to carry out the heat radiation of air forced convection, this will increase the power consumption of fan, and fan is moving component, have noise and integrity problem.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of LED lamp with and radiator structure, have good performance of heat dissipation and insulating properties.
The technical solution of the utility model is:
A kind of radiator structure of LED lamp comprises stream guidance fan housing and heat pipe, and described heat pipe has the condensation end that heating end and stream guidance fan housing are connected.
Described radiator structure, described heat pipe has a plurality of, and described heat pipe is the center with the heating end, and condensation end outwards is distributed on the face vertical with fluorescent tube radially.
Described radiator structure, described heat pipe communicates at the heating end tube hub.
Described radiator structure, described stream guidance fan housing insulate.
Described radiator structure, described stream guidance fan housing are that plastics are made.
Described radiator structure has radiated rib on the described heat pipe.
Described radiator structure, described stream guidance fan housing is less near lamp socket one end opening, and is bigger away from lamp socket one end opening.
A kind of LED lamp comprises metal-back, lamp electrode tip, lamp screw socket in lampshade, led chip, heat pipe, the lamp body, also comprises insulation stream guidance fan housing, heat pipe, and described heat pipe heat absorbing end is close on the led chip, and heat pipe passes lamp body.
Described LED lamp, described metal-back has insulation crust outward.
Described LED lamp, described insulation crust are that plastics are made.
Adopt above-mentioned scheme, the heat pipe heat radiation end of radiator stretches out the outer surface of LED lamp housing, can utilize outer surface, fin to realize high efficiency and heat radiation, the insulation kuppe of radiator outer setting plastic production, kuppe adopts convergent flaring structure, air is accelerated in fin place flowing velocity, strengthened heat exchange.Radiator is arranged on bottom, leaves the natural convection air space, rapid heat dissipation.And kuppe and lamp body outer surface all adopt the plastic material of insulation, and with the inside chip insulation, security is good, strong interference immunity.Without the fan heat radiation, be not provided with moving component, use reliably, energy-conservation, there is not noise.Adopt the heat radiation of similar heat pipe, the radiating efficiency height utilizes the liquid-working-medium accumulation of heat in the heat pipe, and cushioning effect is played in thermal shock.
Description of drawings
Fig. 1 is the schematic diagram of the utility model LED
Fig. 2 is the utility model LED elevational schematic view
Among the figure: insulation stream guidance fan housing 1, lampshade 2, led chip 3, heat pipe 4, radiated rib 5, metal-back 7 in the lamp body 6, lamp body, ambroin shell 8, lamp electrode tip 9, lamp screw socket 10.
The specific embodiment
As depicted in figs. 1 and 2, according to technical scheme provided by the invention, this lamp is made of metal-back 7, ambroin shell 8, lamp electrode tip 9, lamp screw socket 10 and internal circuit in insulation stream guidance fan housing 1, lampshade 2, led chip 3, heat pipe 4, radiated rib 5, lamp body 6, the lamp body.
Its course of work is: when 3 work of LED wick, evolution of heat heating heat pipe 4 internal work liquid, hydraulic fluid evaporation becoming steam, take away heat and be delivered to heat pipe top all around, and heat is dispersed in the air by fin 5, working steam is cooled to liquid by air, under the effect of heat pipe 4 inner imbibition cores, get back to the heat pipe bringing-up section, continue to be heated evaporation, this continuous evaporation and the condensation process of hydraulic fluid, the heat that led chip 3 is given out is delivered in the outside air continuously.
The air of kuppe 1 inside is heated and density diminishes, and under the buoyancy lift effect, air is diffusion upwards, and the air of kuppe 1 below moves upward under pressure differential, continues cooling heat pipe 4 and fin 5 thereof.
The hydraulic fluid of heat pipe 4 the insides changes liquid and can be water, methyl alcohol, ethanol or other liquid for heat absorption liquid, also can be mixtures of different liquids.
The fin that heat pipe is with outward also can change into around sheet or the fin that directly is processed into.
The imbibition core is laid on the inside heat pipe surface, and the imbibition core can be made or directly leave longitudinally groove at inner surface and form with copper powder, the copper mesh of sintering.
The stream guidance fan housing outer surface can be opened ventilative hole or groove.
Metal-back 7 covers without insulating materials in 1 projection section of stream guidance fan housing in the lamp body, and the straight rib of projection also can be made in the surface.
Metal-back 7 can not cover by projection section surface 8 usefulness insulating materials at stream guidance fan housing 1 in the lamp body.
