Embodiment
For clearly understanding the detailed construction of the heat abstractor 2 in the embodiment of the invention, with reference to Fig. 2 A to Fig. 2 C.As shown in Fig. 2 A, the heat abstractor 2 of first embodiment of the invention comprises a housing 20, at least one heat dissipation channel 21, at least one return flow line 22, one first communication channel 23 and one second communication channel 24, its middle shell is made by metal material or nonmetallic materials, helps the dissipation heat.And heat dissipation channel 21, return flow line 22, first communication channel 23 and second communication channel 24 all are positioned at housing 20, have working fluid in the housing 20.First communication channel 23 connects an end of heat dissipation channel 21 and an end of return flow line 22, and second communication channel 24 connects the other end of heat dissipation channel 21 and the other end of return flow line 22, make working fluid can sequential flow behind return flow line 22, first communication channel 23, heat dissipation channel 21 and second communication channel 24, get back in the return flow line 22.The direct of travel of working fluid is shown in the arrow among Fig. 2 A 210,220, by showing among the figure, heat dissipation channel 21 usefulness solid lines are represented, return flow line 22 then dots, on behalf of heat dissipation channel 21 and return flow line 22, this locate respectively to go up at various height, that is to say that heat dissipation channel 21 formed planes are different from 22 formed planes, return flow line.
The heat dissipation channel 21 of heat abstractor 2 of the present invention and the configuration of return flow line 22 refer again to Fig. 2 B for further explaining, this figure is the side-looking generalized section along the heat dissipation channel 21 of heat abstractor 2.The return flow line 22 of heat abstractor shown in the figure 2 is positioned at first surface 200 places near housing 20, and the first surface 200 of housing 20 can be arranged on a thermal source (not shown) place usually; And heat dissipation channel 21 is positioned at second surface 201 places near housing 20, and the second surface 201 of housing 20 can be arranged on temperature usually than the thermal source lower.Thus, when working fluid in the return flow line 22 when flowing, can absorb the heat that thermal source comes out, next, working fluid flow in the heat dissipation channel 21 by first communication channel 23, utilize the second surface 201 of housing 20 that heat contained in the working fluid is taken away again, last working fluid is got back in the return flow line 22 by second communication channel 24 again, forms circulating of working fluid.Make the heat of thermal source can be by heat abstractor 2 dissipations simultaneously, the direction of heat transferred be as shown in arrow 25.Refer again to Fig. 2 C, this figure is the side-looking generalized section of the A-A ' line of Fig. 2 A, as seen from the figure, the plane that heat dissipation channel 21 formed planes and return flow line 22 form is inequality, with this embodiment explanation, the lower edge on heat dissipation channel 21 formed planes the upper limb proper and plane that return flow line 22 forms is in the same plane, can simplify the manufacture method of its heat abstractor 2 like this.But be not limited to this, the upper limb on the plane that the lower edge on heat dissipation channel 21 formed planes also can form with return flow line 22 is positioned on the Different Plane, for example the lower edge on heat dissipation channel 21 formed planes can be higher than the upper limb on the plane of return flow line 22 formation, shown in Fig. 2 D and Fig. 2 E.Like this heat dissipation channel 21 is separated on two different planes fully with return flow line 22, the density that is provided with of heat dissipation channel 21 and return flow line 22 is increased, can produce bigger heat dissipation capacity on the unit are, and needn't worry that the problem that mutual channel disturbs produces.Perhaps also the lower edge on heat dissipation channel 21 formed planes can be designed to be lower than the upper limb on the plane that return flow line 22 forms, technology of the present invention only require heat dissipation channel 21 and return flow line 22 except two ends by first communication channel 23 with second communication channel 24 links to each other, remainder all can not be interconnected and get final product.
In addition, also comprise a dissipation space 27 in the heat abstractor 2 of the present invention, shown in Fig. 2 F and Fig. 2 G.Dissipation space 27 comprises many first dissipation passage 272 and many second dissipation passages 271 that can be communicated to return flow line 22 that can be communicated to heat dissipation channel 21.When working fluid circulates in heat abstractor 2 of the present invention, make the part working fluid produce the phenomenon that flashes to gaseous state as in return flow line 22, having because absorbing the heat of thermal source, the working fluid of these gaseous states can directly dissipate in the dissipation space 27 by the second dissipation passage 271, dissipate to heat dissipation channel 21 by the first dissipation passage 272 again, working fluid can directly dissipate to heat dissipation channel 21 with heat release, flows back in the return flow line 22 by second communication channel 24 again.Certainly, also can be designed to dissipation space 27 and comprise that also many 3rd dissipation passages 273 that can be communicated to first communication channel 23 and many can be communicated to the of the second communication channel 24 ease passage 274 that scatters, to increase the dissipation path of gaseous working fluid, so can improve the radiating efficiency of heat abstractor 2 of the present invention more.
Heat dissipation channel 21 formed planes described in the foregoing description can be as shown in Figure 3A, and wherein the distribution shape of heat dissipation channel 21 can be that a radiation is linear, the radiation wire outwards stretch.Heat dissipation channel 21 is communicated to first communication channel 23 near an end at center, and an end in the heat dissipation channel 21 close outsides is communicated to second communication channel 24, preferably, second communication channel is located on the periphery of first communication channel, and 22 formed planes, return flow line also can be designed to identical with Fig. 3 A, set-up mode does not repeat them here as heat dissipation channel 21 in detail.But heat dissipation channel 21 formed flat shapes are not limited thereto, and also can be circular curve shape and stagger mode or the like, the heat dissipation channel 21 formed planes as shown in Fig. 3 B and Fig. 3 C.With reference to Fig. 3 D, even heat abstractor 2 also can comprise two groups of heat dissipation channels 21 ' and 21 ", two first communicating pipes 23 ' and 23 " and two second communicating pipes 24 ' and 24 "; be configured to the zone of two heat dissipation channels mutually; according to above-mentioned execution mode, also can reach the heat radiation function described in above-mentioned embodiment.The distribution mode of return flow line is identical with above-mentioned heat dissipation channel, does not repeat them here.
According to above-mentioned design, have heat dissipation channel 21 and return flow line 22 that the working fluid cycles of making flows in the heat abstractor 2 described in the first embodiment of the present invention, and heat dissipation channel 21 and return flow line 22 are positioned on the different planes, make the working fluid heat that can in heat dissipation channel 21, leave, and in the return flow line 22 heats that absorb thermal source, can not make working fluid produce disorderly flowing like this, therefore the radiating efficiency of its heat abstractor can improve.And, working fluid in the heat abstractor of the present invention does not need to utilize its liquid characteristic with the gaseous state conversion to implement, that is to say, flowing process fluid in heat abstractor of the present invention, can maintain liquid state fully or maintain fully under the state of gaseous state and all can implement, so, the selectivity of working fluid is also comparatively extensive, can be convenient to use on industry.
