The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
Shown in Fig. 1～5, the loop circuit heat pipe heat abstractor among the present invention comprises an evaporimeter 1 and four pipelines 5 that are communicated with this evaporimeter 1.Be provided with four working media passages 4 in this evaporimeter 1.The two ends of every working media passage 4 are communicated with the two ends of a pipeline 5 respectively, thereby form the closed-loop path of the parallel connection of four rectangles.
In the present embodiment, evaporimeter 1 is provided with a sprue 11 that injects working media in this closed-loop path, is provided with a check valve 3 that is used to seal described closed-loop path at sprue 11 places.This sprue 11 is communicated with four working media passages 4 by a material feeding passage 2 that is arranged in the evaporimeter 1.
This material feeding passage 2 and nonessential inside that is arranged on evaporimeter 1, it can extend to outside the surface of evaporimeter 1.
In addition, material feeding passage 2 is not that the loop circuit heat pipe heat abstractor must be established yet, it can be and is independent of this loop circuit heat pipe heat abstractor and sets up outward, can be provided with a sprue this moment separately on the conduit wall of every working media passage 4, all dispose a switch on each sprue, described four working media passages 4 can be separate.Material feeding this moment passage adopts external mode, can play equally many working media passages 4 are carried out the purpose that working media injects operation simultaneously.
Need to prove that those skilled in the art also can be provided with a sprue on every pipeline 5, and be provided for sealing the switch of closed-loop path on this sprue, is that every closed-loop path is injected working media separately from sprue.Certainly, also can a material feeding pipeline that be communicated with four pipelines 5 be set, the sprue of an outfit switch is set on this material feeding pipeline in the part beyond the evaporimeter 1 of loop circuit heat pipe heat abstractor.Above-mentioned two kinds of schemes can reach equally and form the loop among the present invention earlier, and the purpose of working media is injected in the back.
Finish because pipeline 5 has been connected before injecting working media with evaporimeter 1, only need directly to carry out material feeding to the loop circuit heat pipe heat abstractor, directly close the closed operation that check valve 3 is just finished this device after material feeding finishes by this material feeding passage 2.Exist pressure differential with the external world in the pipeline after having avoided heat abstractor of the prior art because of the injection working media, cause joint to be revealed easily, thereby make the situation of welded closure process complications, also do not need to be equipped with the large-scale apparatus of specialty, reduced processing cost.
In addition, the material feeding passage more than two or two can be set on this evaporimeter 1,, save the material feeding time to accelerate material feeding speed.
Moreover, be used for this loop circuit heat pipe heat abstractor is fixed to installing hole 6 on the equipment to be dispelled the heat also being provided with on the evaporimeter 1 in the various embodiments described above.
In order further to improve the radiating effect of this loop circuit heat pipe heat abstractor, some radiating fin (not shown) can be set on above-mentioned pipeline 5.
Before injecting working media, the porch by this material feeding passage 2 vacuumizes operation to the loop, injects working media subsequently, starts check valve 3 loops after the medium injection work of finishing the work.Thereby make the working media in the loop to be issued to boiling point, improve its radiating efficiency in a lower temperature.
Need to prove, the closed-loop path structure of rectangle is not to limit the invention in the present embodiment, those skilled in the art can carry out conversion to the shape of closed-loop path as required, for example adopt the loop structure of the annular shown in Fig. 6, treat the needs of heat dissipation equipment with cooperation.
Same, the present invention is also unrestricted to the number of evaporimeter, and those skilled in the art can adopt a plurality of evaporimeters that distribute side by side according to actual conditions.For example, as shown in Figure 7, can adopt three evaporimeters 1 side by side, adjacent two evaporimeters, 1 a relative side adopts pipeline to connect.This structure can be used for the heat radiation of main equipment, is convenient to from diverse location injecting working media the loop circuit heat pipe heat abstractor.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited by appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
