The round tube periphery wall of one end is equipped with multiple fins 21, and multiple fins 21 are arranged in the shape of a spiral along the axial direction of heat pipe 20, works as air
Fin 21 is flowed through, since spiral helicine fin 21 has helix angle, air flow direction is not straight line but a kind of turbulent condition, figure
Arrow direction is the direction of wind in 4, and in this way under conditions of low wind speed, the convective boundary layer of the wall surface between adjacent fins 21 is more
It is easy to upset, to obtain better heat exchange property.Especially present optical communication equipment integrates more functions, and volume becomes
Small, fan volume is also smaller and smaller, and under conditions of low wind speed, the better optical communication radiator of performance can be more favourable.
Illustratively, as shown in figure 3, heat pipe 20 is equipped with bending section, one end of substrate 10 is arranged in heat pipe 20 for bending section
Heat pipe 20 be arranged fin 21 one end between, bending section be also it is flat, be gradually transitions the circular tube shaped at fin end.Heat pipe 20
Bending section is set it is the installation in order to adapt to different optical communication radiators, those skilled in the art can set according to actual needs
It sets.
The heat pipe 20 of the present embodiment is sintered using the copper fin pipe of rolling, then according to the processing technology of conventional heat pipe
It is shaped to 20 structure of heat pipe shown in Fig. 3, finally the optical communication radiator integrally welded with substrate 10.Using rolled fin
Pipe, the parameter of fin 21, such as spacing, piece are thick, height can freely be adjusted by heat pipe process equipment.Identical material can be with
Different parameters is adjusted, without in addition opening up fin die, processing cost is saved, reduces processing technology.Integrally roll
The helical fin 21 of heat pipe 20 under low wind speed condition, can pass through fin 21 in the bigger optical communication equipment of density of texture
Between air turbulence, obtain better heat dissipation performance.
Contact chip 30 is set on the flat end of heat pipe 20, and contact chip 30 is copper sheet, and specifically, material can be fine copper
C1100, the material have good conductive, thermally conductive, anti-corrosion and processing performance, can weld and be brazed.
Illustratively, optical communication radiator provided by the embodiment of the utility model is in use, as shown in figure 4, heat source is optical mode
Plate 40, optical mode plate 40 from Fig. 4 show position be inserted into from left to right with 10 plane contact of optical communication radiator base plate, due to optical mode plate 40
There can be dimensional tolerance with the processing of optical communication radiator, prevent optical mode plate 40 and optical communication radiator plane from being bonded completely, such as
Fruit plane contact is bad, and heat, which concentrates on optical mode plate 40 will cause optical mode plate 40, to be stopped working or even burn out, but by light
The top for communicating radiator increases a spring 12, and spring 12 makes optical communication radiator have the effect of floating mount, makes it more
Good fitting optical mode plate 40 has more reliable installation capability.Optical communication radiator base plate 10 is under the conditions of 12 active force of spring
Plane can float up and down, to promote the plane of optical mode plate 40 well to contact with optical communication radiator base plate 10, and then heat
It can be transmitted on optical communication radiator base plate 10 and spread, then by contact chip 30, conduct heat to the flat end of heat pipe 20, heat
The quick thermal transport property of heat-conduction principle and phase change medium is utilized in pipe 20, through heat pipe 20 that the heat of thermal objects is rapid
It is transmitted to outside heat source, its working principle is that the heat on optical mode plate 40 is conducted to the flat end of heat pipe 20, the working solution in tube core
Body is taken away the heat of optical mode plate 40 by thermal evaporation, which is the evaporation latent heat of working fluid, and steam is flowed to from central passage
The condensation segment (i.e. round tube end) of heat pipe 20, condenses into liquid, while releasing latent heat, under the action of capillary force, liquid reflux arrives
Evaporator section (i.e. flat end) a, in this way, closed circulation is just completed, to conducting a large amount of heat from flat end to tail portion
The heat dissipation of round tube end.
Optical communication radiator provided by the embodiment of the utility model, good heat dissipation effect is small in size, by rolled finned tube application
Onto heat pipe 20,21 parameter of fin of heat pipe 20 is freely adjusted by heat pipe process equipment, reduces fin die sinking, reduces processing work
Sequence, save the cost.
Optical communication radiator provided by the embodiment of the utility model, using tin cream as solder flux, by heat pipe 20, substrate 10,
Spring 12 and contact chip 30 weld together, and make the integrally molded molding of optical communication radiator of the present embodiment.
