And the shape of folding shape radiating tube 2 lateral cross section can be rectangle or circle or class rectangle, and the shape of through hole also is rectangle or circle or class rectangle thus.The folding shape radiating tube 2 of present embodiment is for replacing the folding shape radiating tube of broken line, like this can be so that the backflow of working medium 14 is more smooth and easy, Figure 14 and shown in Figure 15 for another example, be respectively seven of the utility model radiator perspective view, with four of side sectional view, folding shape radiating tube 2 also can be level and the folding shape radiating tube that intersects vertically and replace, because folding shape radiating tube 2 has certain angle of inclination in the horizontal direction, helps the condensing reflux of working medium 14.
And the waveform radiating fin that radiating fin 3 continuous bending that is tinsels or punching press form, the longitudinal section of waveform radiating fin can be continuous " U " shape or " V " shape or circular arc or linear, and present embodiment is a linear, is not limited thereto certainly.
The concrete course of work of present embodiment heat-pipe radiator is: at first, be evacuated in the cavity 10 with pedestal 1, charge into the liquid or the solid-state working medium 14 of meeting the heat vaporization, meeting the condensation knot then.In use, heat absorption end face 12 applyings of pedestal 1 are installed on the thermal source, the heat that thermal source produced is transmitted to pedestal 1 by heat absorption end face 12, because cavity 10 is arranged in the pedestal 1, and be filled with working medium 14 in the cavity 10, therefore pedestal conducts the heat of thermal source to the working medium 14 in the cavity 10, working medium 14 vaporization evaporations enter folding shape radiating tube 2, carry out heat exchange by folding shape radiating tube 2 folding shape radiating tubes 2 with surrounding medium (for example air), and folding shape radiating tube 2 with most of heat conduct to radiating fin 3 that its wall is connected on, radiating fin 3 and surrounding medium carry out heat exchange.After the heat exchange, the working medium condensing reflux in the folding shape radiating tube 2 is in the cavity 10 of pedestal 1, and wherein most of working medium 14 is back in the cavity 10 of pedestal 1 by return duct 4.In the cavity 10 of pedestal 1 and folding shape radiating tube 2, formed the phase transformation shuttling movement of heat-transfer working medium thus.
Because in the work of radiator of the present utility model, working medium by liquid or solid-state become gaseous state after, volume increases several times, so the pressure in pedestal 1 and the folding shape radiating tube 2 increases, because be provided with reinforcement 21 in the folding shape radiating tube 2, therefore can well prevent the deformation of flat-shaped folding shape radiating tube 2.Prior art it has been generally acknowledged that increases effective support that fin or other supporting constructions can realize opposite heat tube in the heat pipe outside, but operation principle from heat pipe, the power that causes the heat pipe distortion is from inside heat pipe, heat pipe is subjected to the extruding of internal pressure, the supporting construction that is arranged on the outside only can provide support power, can't effectively strengthen the heat pipe anti-pressure ability, therefore only have the level of EXS heat pipe, vertical direction size to be greatly limited.When less or heat-dissipating space is long and narrow when the thermal source area, only there is the heat pipe of external support structure can not be made into longer size to adapt to such heat radiation situation.And in the present embodiment, increased reinforcement in the inside of folding shape radiating tube, and can provide measuring body internal tension for heat pipe, effectively overcome the problem on deformation of heat pipe.It is to overcome under the prerequisite that has the processing technology restriction now to finish that present embodiment increases reinforcement at inside heat pipe, and the raising of folding shape radiating tube body processing technology level is the prerequisite that realizes present embodiment.Prior art can't add reinforcement in light-wall pipe, therefore all do not have reinforcement in the light-wall pipe of this yardstick, and the utility model has added reinforcement, has effectively strengthened the bearing capacity of light-wall pipe, has reduced the size restrictions to light-wall pipe.
The advantage of the utility model heat-pipe radiator is: be provided with cavity in the pedestal, the heat of thermal source directly conducts the liquid working substance of giving in the cavity through the heat absorption end face of pedestal, so thermal resistance is minimum, so can give full play to the conductive force of heat pipe in the radiator; Folding shape radiating tube can be rapid with the conduction of heat, effective along stretching, thermal resistance is almost nil, and, because heat can extend rapidly by in the vertical direction, so present embodiment can be applicable to the heater element that the thermal source area is less, rapidly heat is directed on the vertical direction and dispel the heat, played better heat radiating effect; The cavity of folding shape radiating tube in pedestal is interconnected, and the bend pipe that is, the circulation of liquid working substance in the folding shape radiating tube that helps being communicated with, be present in the circulation that the small pressure reduction of rolling in the shape radiating tube both sides can help liquid working substance, thereby there is the dead angle of heat conduction hardly in the present embodiment heat-pipe radiator, and heat-conducting effect increases substantially; Do not exist the technical characterictic at circulation dead angle when vacuum pumping, can also improve the vacuum degree of acquisition in the folding shape radiating tube; Present embodiment is connected with parallel intensive radiating fin between folding shape radiating tube, the heat of vertical direction transmission also can be extended rapidly in the horizontal, and radiating fin increased area of dissipation, makes radiator have better heat radiating effect.
More crucial is, in the heat-pipe radiator of the present utility model, folding shape radiating tube can the one extrusion modling, and be single radiating tube folding shape heat transferred, it is big to have solved heat-pipe radiator pipe joint welding job amount preferably, easily leaks, rate of finished products is low, causes the high problem of cost.Simplified the course of processing, present embodiment is strong in industrial realizability, and the simplification of processing technology can significantly reduce cost.In addition, because the cavity of folding shape radiating tube is communicated with the cavity of pedestal, so pedestal 1 can be processed as base material, through hole aperture on the pedestal is identical with the orifice configuration of folding shape radiating tube, and it is parallel in twos, when folding shape radiating tube is connected on the through hole, integrated folding shape radiating tube is connected the also fixing keeping parallelism of an end on the through hole, the folding shape radiating tube of the equal secured in parallel in two ends is not yielding in the course of the work like this, thereby the heat-pipe radiator of this planform is not only simple in structure, and it is support strength is big, so practical.
The technical solution of the utility model can adapt to complicated more heat radiation situation, heat-dissipating space outside the radiating surface of thermal source is narrow and small, can't hold heat-pipe radiator, then can adopt the technical scheme of present embodiment, then the heat dissipation direction of heater element is not limited on the vertical direction of its radiating surface.Liquid working substance can be realized good circulation in the cavity of pedestal, the circulation dead angle of heat conduction can not occur.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
