Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Embodiment: refer to shown in Fig. 1 ~ 4, the one-way circulation for oscillatory type heat-transfer device of the present invention starts preferably implementing of structure
Example, only these embodiments are intended for purposes of discussion, are not limited by this structure in patent application.
Described oscillatory type heat-transfer device A includes a housing 10 and is located at this primary Ioops type runner 20 within housing 10,
This loop type runner 20 includes heated section 23,1 first side water conservancy diversion section 21 and an one second side water conservancy diversion section 22, and should
Being equipped with a working solution 30 in loop type runner 20, working solution 30 evaporation of this heated section 23 forms steam pressure to promote work
Make liquid 30 to flow；And wherein, at least side of this second side water conservancy diversion section 22 is provided with and protrudes out in blind hole form at least towards side
One forked choked flow road 40, between this forked choked flow road 40 and second side water conservancy diversion section 22 and formed one fall fork edge 41, should fall fork
Edge 41 protrude out direction with from working solution 30 moving direction (as shown in the arrow W1 of Fig. 2) contrary of this heated section 23.
By said structure composition form and technical characteristic, the actual operation state of oscillatory type heat-transfer device A of the present invention is first
First as in figure 2 it is shown, the heated section 23 of this loop type runner 20 is contacted with an existing pyrotoxin 50, forked choked flow road for arranging
40 may be used to retardance from heated section 23 towards the working solution 30 (as shown in arrow W2) of the second 22 sections of movements in evaporating area, side, and phase
Working solution 30 (as shown in the arrow W1) flow regime that promotion is moved towards the first side water conservancy diversion section 21 from heated section 23, from
And as it is shown on figure 3, accelerated the reaching (such as Fig. 3 of oscillatory type heat-transfer device A internal work liquid 30 one-way circulation starting state
Circulating path shown in arrow W1).This Duan Zhongxu remarks additionally, and why described forked choked flow road 40 can be to from heat affected zone
Section 23 produces retardation towards the working solution 30 of the second 22 sections of movements in evaporating area, side, is primarily due to working solution 30 and moves to forked
During choked flow road 40, the blind hole form in forked choked flow road 40 protrudes out direction and the work from heated section 23 plus falling to pitch edge 41
The morphological characteristic of liquid 30 moving direction (as shown in the arrow W1 of Fig. 2) contrary, can make the working solution 30 passed through produce backflow existing
As (as shown in the arrow L1 of Fig. 2), this backflow phenomenon, can make from heated section 23 towards the work of the second 22 sections of movements in evaporating area, side
Make liquid 30 to produce retardation and reduce this lateral pressure.
As shown in Figures 1 to 4, wherein said oscillatory type heat-transfer device A can be set as a hot plate form, so that described housing 10 includes phase
In conjunction with fixing substrate 101 and a cover plate 102, described loop type runner 20 is made to be located at substrate 101, cover plate 102 at least
One of which (note: this example is only located in substrate 101 structure), and described forked choked flow road 40 is set as oblique protruding out form.
As it is shown in fig. 7, wherein said oscillatory type heat-transfer device A2 also can be set as a heat pipe form, so that described housing 10B
Constituted and one first pipe end 11 and one that includes being mutually butted combination by being bent into primary Ioops form by a hollow pipe
Two pipe ends 12, and it is forked to be formed to be provided with the form of a tapered tube wall 13 by first pipe end the 11, second pipe end 12 one of which
Choked flow road 40B, and formed to fall to pitch edge 41B by the end of first pipe end the 11, second pipe end 12 one of which.Shown in this example
Feature is still with the presence of its different changes on implementing, and this part is as it is shown in fig. 7, make its first pipe end 11 form tapered tube wall
13, the second pipe end 12 is then the set group straight wall form in this first pipe end 11 periphery, so that forked choked flow road 40B is formed at described
Between tapered tube wall 13 and the second pipe end 12；For another shown in the embodiment of Fig. 8, its first pipe end 11C is made to be set as straight wall form,
Second pipe end 12C then set group is in the first pipe end 11C periphery and forms this tapered tube wall 13C, so that forked choked flow road 40C is formed at
Between this tapered tube wall 13C and first pipe end 11C.
Wherein, forked choked flow road 40,40B can be formed at the two sides symmetrically configuration of the second side water conservancy diversion section 22.
As it is shown in figure 5, the most forked choked flow road 40 also can be formed at two sides of the second side water conservancy diversion section 22 in each other
Dislocation configuration.
And the forked choked flow road 40 shown in Fig. 6, then it is the configuration being only formed at the second single side of side water conservancy diversion section 22.
Advantages of the present invention illustrates:
The one-way circulation of the present invention a kind of oscillatory type heat-transfer device starts structure, main by described housing, loop type runner, fork
Shape choked flow road, fall innovation unique texture form such as fork edge etc. and technical characteristic, make the present invention compare background technology and withdrawn deposit knot
For structure, forked choked flow road may be used to the working solution that retardance is moved towards the second side water conservancy diversion section from heated section, and relatively promotes
The working solution flow regime moved towards the first side water conservancy diversion section from heated section, thus reach to accelerate inside oscillatory type heat-transfer device
The practical improvement of working solution one-way circulation starting state.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not limit the scope of the invention with this.All according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within protection scope of the present invention.
