The specific embodiment
Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however appended accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.
See also Fig. 1 and Fig. 2, be respectively three-dimensional exploded view of the present utility model and stereo appearance figure of the present utility model, the utility model provides a kind of temperature-uniforming plate 1 with shim 30, comprise a housing 10, a capillary structure 20, a shim 30, a supporting construction 40 and a working fluid 50 (see figure 4)s, wherein:
It is one horizontal that shim 30 is.Shim 30 parts repeatedly place on the capillary structure 20.And shim 30 central parts are provided with a corresponding room 111 and a rectangular through slot 31, so that room 111 can communicate with last coverboard 12.In addition, be formed with a fluid passage b (see figure 4) between following coverboard 11 and the shim 30.Further specify, in fact fluid passage b is the capillary structure 20 that is laid in down coverboard 11 inwalls.In addition, the downward bending forming in shim 30 corresponding through slot 31 positions has a plurality of tabs 32, and these tabs 32 are positioned at two opposite side of through slot 31, and tabs 32 stretches into room 111 inside.Supplementary notes, the end of tabs 32 all is connected to capillary structure 20, and an end face of tabs 32 also amplexiforms in capillary structure 20.
Supporting construction 40 is placed in housing 10 inside, and supporting construction 40 comprises a plurality of wave sheets 41 that mutual dislocation is arranged.The upside of wave sheet 41 and downside are formed with a plurality of grooves 411 respectively.Supporting construction 40 upper and lower sides (being the crest and the trough of wave sheet 41) respectively with last coverboard 12 and shim 30 mutual butts.Be formed with a gas passage c who communicates with fluid passage b and go up between coverboard 12 and the shim 30.Further specify, gas passage c is formed passage between each wave sheet 41 of supporting construction 40.Working fluid 50 (see figure 4)s are then filled in housing 10 inside.In addition, 30 both sides of the shim in housing 10 are formed with the connection district d that gas passage c is communicated with fluid passage b respectively.
See also Fig. 3 and Fig. 4, be respectively among Fig. 2 along the cutaway view of 3-3 hatching and the partial enlarged drawing of the part of the A among Fig. 3, when temperature-uniforming plate 1 was not heated, liquid phase working fluid 50 lodged in the room 111.When the used heat of electronic heating component (figure do not show) conducted in the following coverboard 11 of temperature-uniforming plate 1, liquid phase working fluid 50 will be heated and change vapour phase working fluid 50 into and travel up to coverboard 12.Go up coverboard 12 places when working fluid 50 arrives, just can enter gas passage c to two side flow.When gas coming through passage c, working fluid 50 just can discharge heat, heat is seen through last coverboard 12 spread out of.
When working fluid 50 arrives the both sides of housing 10, owing to working fluid 50 release heat, so working fluid 50 will be converted to liquid phase again by vapour phase.Because the relation of gravity and capillary structure 20, working fluid 50 will flow back to room 111 by fluid passage b.Therefore, vapour phase and liquid phase working fluid 50 will be not mutual interference and reduce the heat dissipation of temperature-uniforming plate 1 mutually.In addition, the effect of tabs 32 is, prevent that vapour phase working fluid 50 from being refluxed by fluid passage b, and liquid phase working fluid 50 is produced the phenomenon that obstructs, and the end face of tabs 32 and end amplexiform and are connected to capillary structure 20 respectively, can significantly reduce the probability that vapour phase working fluid 50 is back to fluid passage b.
See also Fig. 5 and Fig. 6, be respectively the three-dimensional exploded view of another embodiment of the utility model and the sectional view of another embodiment of the utility model, in the present embodiment, temperature-uniforming plate 1 comprises a housing 10, a capillary structure 20, a shim 30, a supporting construction 40 and a working fluid 50 (see figure 6)s, wherein:
The view 6 of please knowing clearly, the end face of following coverboard 11 1 sides amplexiforms on a heat generating component 60.In addition, be formed with a connection district d who communicates with fluid passage b and gas passage c respectively in shim 30 both sides of housing 10 inside.
When working fluid 50 is heated, it will change vapour phase working fluid 50 into, flow left in gas passage c.When working fluid 50 flows to the left side of shim 30, working fluid 50 will be emitted heat, and transform back into liquid phase working fluid 50, and flow back to heat generating component 60 to the right from fluid passage b.So repeat heat exchange, to take away the heat that heat generating component 60 is produced.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
