[specific embodiment]
By the technological means of the structure of further understanding the present invention, utilization is promptly expected the effect of reaching, now lift several preferred embodiments and cooperate diagram to be described in detail as follows, believe the present invention's creation purpose, feature and other characteristics, when can going deep into therefrom and concrete understanding.
As shown in Figure 2, mainly in hollow tube 10, be provided with capillary structure 20, the middle circulation road 30 that forms, on capillary structure 20, front and back two end appropriate locations are made as endotherm section 21 and radiating segment 22 respectively, between two sections, be provided with one and add short section 23, this formation that adds short section 23 be on this capillary structure 20 by endotherm section 21 and radiating segment 22 gradually to short section 23 thickenings of adding of central authorities, make first cross section 31 (as shown in Fig. 2 (B)) that adds short section 23 second cross section 32, the 3rd cross section 33 (as shown in Fig. 2 (A)) less than endotherm section 21 and radiating segment 22 2 ends.In other words, the circulation road 30 in the body 10 forms a funnel-form, and the diameter of two ends is broad, and the diameter of central authorities is narrower.
It more than is the general introduction of structure, position and the interconnected relationship of each element of the present invention; Then, again with the combination of each element of the present invention and expect the effect statement as the back of reaching:
As shown in Figure 3, in use, the liquid 40 of this body 10 forms the steam 41 that can take heat after endotherm section 21 absorbs heat energy, because the endotherm section 21 of body 10 and radiating segment 22 temperature difference relation, this steam 41 is promptly desired to take to radiating segment 22 by endotherm section 21.
This steam 41 is taken to radiating segment 22 by endotherm section 21, urged section at 23 o'clock through adding in its way, because first cross section 31 (as shown in figure two B) of circulation road 30 is less than second cross section 32 of two ends, the 3rd cross section 33 (as shown in figure two A), can quicken flowing through fast of steam 41, to quicken the type of flow heat energy is brought to radiating segment 22 by endotherm section 21 relatively, by the radiating fin (not drawing among the figure) of radiating segment 22 heat energy is taken out of again, forming liquid sucks back to endotherm section 21 by this capillary structure 20 again, and the steam behind the absorption heat energy 41 quickens to flow through this and adds short section 23, its temperature is cooling in advance simultaneously, can quicken to form liquid at radiating segment 22, so that capillary structure 20 sucks back.
