Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in Figs. 1-2, which includes a cuboid heat pipe 1 with four side of both ends of the surface, in the heat pipe
Substrate is fitted with 1 four sides, substrate is pcb board, and substrate is bonded in by heat-conducting glue on the side of heat pipe 1, substrate
On the position of 1 end face of heat pipe is provided with LED lamp bead 2, four LED lamp beads 2, and four are mounted on each substrate
LED lamp bead 2 is inline, and is parallel to each other with heat pipe 1.Irradiation can be made by being respectively provided with LED lamp bead 2 on four sides of heat pipe 1
Light there is good light-gathering, and uniform illumination, unobstructed shade.When LED car lamp works, LED lamp bead 2, which shines, produces heat
Amount, heat are sent on heat pipe 1 by substrate, and the heated liquid in heat pipe 1 evaporates rapidly, and the liquid of vaporization is in small pressure differential
The lower other end for flowing to heat pipe 1, the gradual precooling in flow process of the liquid of vaporization is condensed into liquid, and discharges heat, again
The liquid of condensation then flows back to the institute of LED lamp bead 2 at one end again by the porous material in heat pipe 1 by capillary force effect, so not
Disconnected circulation, the heat that LED lamp bead 2 produces constantly reach the one end of heat pipe 1 away from LED lamp bead 2 by one end of heat pipe 1, and this
Circulation carries out quickly, therefore heat can must continually be conducted and.
Further, wind turbine 6 is fixed with the other end of heat pipe 1, and wind turbine 6 is furnished with fan shroud 12, to protect wind
The normal operation of machine 6, prevents impurity particle from being damaged into wind turbine 6 to the fan of wind turbine 6；In LED lamp bead 2 and wind turbine 6 it
Between be provided with the radiator 3 for being connected with substrate thermal conductivity and connecting with wind turbine 6, wind turbine 6 is fixed on radiator 3 by screw
On.As shown in figure 3, the radiator 3 includes heat radiator body and the heat sink 4 being fixed in heat radiator body, the heat dissipation is originally
The central axis of body offers the through hole for accommodating heat pipe 1, and the heat radiator body is cylinder, or cuboid or other shapes
Shape, and heat radiator body is integrally formed with heat sink 4.Heat radiator body outside wall surface arranged for interval described in 4 ring of heat sink, and dissipate
Backing 4 and the central axes of heat radiator body are parallel to each other, and are additionally provided with diversion trench 5 in close 6 side of wind turbine on heat sink 4.It is described
Diversion trench 5 is inclined to set, concretely curved surface or tapered plane, and the initiating terminal of the diversion trench 5 is radiator 3 and wind turbine 6
Connected end, so set, can make the air-flow that wind turbine 6 blows along heat sink 4 guiding of diversion trench 5 and flow, be obliquely installed
Diversion trench 5 can also make the air-flow that wind turbine 6 blows convert flow direction along diversion trench 5, concentration is blown to heat radiator body and heat sink 4
On air-flow be changed into 3 surrounding of radiator dissipate air-flow, i.e., from parallel to 3 central axis direction of radiator change into perpendicular to dissipate
Hot 3 central axis direction of device, hits the heat radiator body of radiator 3 so as to avoid the air-flow that wind turbine 6 blows and rebounds and turn back, make wind
The air-flow that machine 6 blows can possess enough wind pressure；Meanwhile when air-flow is directed to be changed into the air-flow dissipated to 3 surrounding of radiator
Afterwards, the air-flow of the direction can also promote the air flow of air-flow and radiator 3 surrounding of the flowing between multiple heat sinks 4,
Therefore radiator 3 can be enable to make full use of 6 blow flow of wind turbine to reach good heat dissipation effect.
The LED car lamp further includes the deck being sleeved on heat pipe 1, and the deck is by deck axis 7, deck set 8 and is arranged
Spring 9 on deck set 8 forms.Deck axis 7 includes deck axis fixed part and deck axis connection portion, and deck axis fixed part with
Deck axis connection portion is integrally formed.The deck axis fixed part is fixedly connected with 6 end face of remote wind turbine of radiator 3, and logical
Screw is crossed to be connected with radiator 3；The deck axis connection portion is used for the mutually clamping of deck set 8 with being securable on vehicle lamp body
So that the LED car lamp is installed at the light bulb of headlight for vehicles.
As shown in figure 4, deck set 8 includes deck set fixed part and deck set connecting portion, and deck set fixed part with
Deck set connecting portion is integrally formed；Card slot 11 is equipped with the side wall of deck set connecting portion, and in deck axis connection portion side
Wall is equipped with the protrusion 10 with 11 Corresponding matching of card slot, so that deck axis 7 is socketed on by protrusion 10 and the cooperation of card slot 11
On deck set 8, at the same the spring 9 being sheathed on deck set connecting portion be compressed into deck axis fixed part and deck set fixed part it
Between, and the spring 9 compressed gives deck axis fixed part respectively and deck covers the opposite bounce of fixed part, so that deck
In the firm card slot 11 being connected on deck set 8 of protrusion 10 on axis 7, so that both will not divide easily in the case where no external force acts on
Leave and.Therefore, the spring 9 for covering 8 using deck axis 7, deck and being sheathed on deck set 8 can become car light installation process
It is simple and practicable, and firmly install.When being installed to car light, deck set 8 is removed from car light, while lamp housing will be installed on
On Spring Card remove, by Spring Card by deck set 8 deck cover fixed part be fixed on lamp housing, then spring 9 is arranged
On the deck set connecting portion of deck set 8, the deck axis connection portion of deck axis 7 is placed in deck set connecting portion, passes through external force
Spring 9 is compressed so that the protrusion 10 in deck axis connection portion be placed in deck set connecting portion card slot 11 in, then clockwise rotation
Turn deck axis 7, so just the LED car lamp is fixed on the lamp housing of headlight for vehicles using the bounce of spring 9.
The LED car lamp of the utility model when in use, by being set on heat pipe 1, wind turbine 6, radiator 3 and radiator 3
