Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Using method of the present utility model is as follows:
Refer to Fig. 1, the utility model heat abstractor comprises a body 1, in described body 1, be provided with a chamber 11, described chamber 11 comprises one first side 111 and one second side 112, is respectively equipped with one first capillary structure 1111, one second capillary structure 1121 and a working fluid 2 on described the first side 111 and described the second side 112.One side of described the first capillary structure 1111 is connected with described the second capillary structure 1121.The common steam channel 113 that forms of one side of described the first capillary structure 1111 and described chamber 11.
Wherein, the radially expanded range of described the first capillary structure 1111 is more than or equal to the half of the inwall circumference of described chamber 11, and the radially expanded range of described the first capillary structure 1111 is greater than the radially expanded range of described the second capillary structure 1121.
Refer to Fig. 2 and Fig. 3, the outside of the first side 111 of described body 1 and a thermal source 4 contact.One end of thermal source 4 described in one end in contact of described body 1, the other end of described body 1 contacts a radiating subassembly 5.
The overall volume of the first capillary structure 1111 of described body 1 is greater than the overall volume of described the second capillary structure 1121.The scope extending longitudinally of described the first capillary structure 1111 is more than or equal to the half of the tube wall circumference of described chamber 11.Described the first capillary structure 1111 is arranged on described body 1 and the first corresponding side 111 of described thermal source 4.Described the second capillary structure 1121 is arranged on second side 112 corresponding with described the first side 111.The heat that described thermal source 4 produces makes the working fluid 2 in described the first capillary structure 1111 be subject to thermal evaporation, and the working fluid 21 that the working fluid 22 of described liquid state is converted to gaseous state spreads to the second capillary structure 1121 of the second side 112 that is arranged on described body 1.The working fluid 21 of described gaseous state is at the cooling liquid working fluid 22 that condenses in described the second side 112.The working fluid 22 of described liquid state is back to described the first capillary structure 1111 by described the second capillary structure 1121 under the effect of gravity.
Because described working fluid 2 is converted in liquid process and is needed to spread to described the second capillary structure 1121 from described the first capillary structure 1111 by the steam channel 113 of described body 1 by gaseous state, and the volume of described the second capillary structure 1121 is less than the volume of described the first capillary structure 1111, the pressure-acting of the working fluid 21 that has reduced described gaseous state in the time of diffusion, has increased the cycle efficieny of described working fluid 2.Described working fluid 2 is passed to heat away from the position of described thermal source 4 and dispels the heat, and makes can not accumulate too much heat near the position of described thermal source 4, has improved the radiating efficiency of described body 1.
These are only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure that utilizes the utility model description and accompanying drawing content to do; directly or indirectly be used in other relevant technical fields, all in like manner within scope of patent protection of the present utility model.
