Description
Technical field
The utility model relates to a kind of temperature-uniforming plate, relates in particular to a kind of temperature-uniforming plate that improves the product percent of pass of manufacturing and increase the stability when using.
Background technology
The heat abstractor of general known computer main frame cooperates the radiating fin group to be constituted with fan.Allow the radiating fin group absorb the heat that central processing unit (CPU) is produced, utilize the fan steering current again, reach the effect of leading heat radiation to the radiating fin group.Yet, dispel the heat in the fan forced convection mode, problems such as power consumption, noise and life-span weak point can have been produced because of this fan, therefore, if can use heat pipe (Heat Pipe) that the heat that central processing unit produces is delivered to heating radiator (Heat Sink) or counter body, then this passive radiating mode has advantages such as not power consumption, noiselessness, life-span length.
General known temperature-uniforming plate 4 as shown in Figure 1, includes loam cake 41, lower cover 42, capillary structure 43 and supporter 44.Supporter 44 is arranged in the capillary structure 43, and upper and lower cover 41,42 lids are located at the outside of capillary structure 43.Joint on upper and lower cover 41,42 4 limits is engaged with welding manner, pour into required working fluid after, again to the inside state that is evacuated.Thus, form a temperature-uniforming plate.
Though can constitute temperature-uniforming plate 4 with above-mentioned mode, but because temperature-uniforming plate 4 is engaged four limits of upper and lower cover 41,42 in the mode of welding, therefore the length of welding is quite long, thereby also increased the time of welding relatively, formality when causing making is complicated, has reduced its practicality and economic benefit.In addition, temperature-uniforming plate 4 regular expanding with heat and contract with cold, and different with the expansion coefficient of solder flux because of upper and lower cover 41,42 very easily are pulled away from from weld and form the slit; And temperature-uniforming plate 4 is after being heated, and portion produces high temperature and high pressure within it, normal local flaw because of weld, and the joint of upper and lower cover 41,42 is split, the liquid vapour phase of carrying out that temperature-uniforming plate 4 can't be stable is changed.
Content of the present utility model
Fundamental purpose of the present utility model is to provide a kind of temperature-uniforming plate, and it is by reducing the weld length of tabular cylindrical shell and capping, thus the stability when improving the manufacturing qualification rate of temperature-uniforming plate and increasing use.
To achieve these goals, a kind of temperature-uniforming plate of the utility model comprises:
Tabular cylindrical shell, it has at least one opening;
Heat conductor is arranged in this tabular cylindrical shell; And
Capping, involution are connected the opening part of this tabular cylindrical shell.

Embodiment
Fig. 2, Fig. 3 and Fig. 4 are respectively three-dimensional exploded view, assembled sectional view and the other direction assembled sectional view of the utility model first embodiment.The utility model provides a kind of temperature-uniforming plate, can improve the manufacturing qualification rate of temperature-uniforming plate and increase temperature-uniforming plate the stability when using.As Fig. 2, Fig. 3 and shown in Figure 4, this temperature-uniforming plate is made of tabular cylindrical shell 1, heat conductor 2 and capping 3.
Tabular cylindrical shell 1 can be the hollow tube of rectangular tube, oval pipe or other various different geometries.Tabular cylindrical shell 1 has at least one opening 11, has two openings 11 in the present embodiment.
Capping 3 by a base plate and around the base plate extended side plate constituted, and its involution is connected two openings, 11 places of tabular cylindrical shell 1.The centre of capping 3 is provided with communicating pipe 31 forwardly, is used for the filling of working fluid and vacuumizes operation.
Fig. 3 and Fig. 4 are respectively assembled sectional view and the other direction assembled sectional view of the utility model first embodiment.As shown in Figures 3 and 4, during making, the capillary structure 21 and the supporter 22 of heat conductor 2 are inserted from an opening 11 of tabular cylindrical shell 1; With the opening 11 of capping 3 involutions, and be welded to connect at capping 3 periphery with opening 11 joints at tabular cylindrical shell 1; From the communicating pipe 31 of capping 3 injecting an amount of working fluid, this working fluid can be low-boiling liquid such as pure water, methyl alcohol, acetone; Afterwards, with heating mode the air of inside is discharged the formation vacuum state again.In addition, the opening 11 of tabular cylindrical shell 1 of the present utility model engages the place with capping 3, and the length of required welding is short, thereby the manufacturing qualification rate of temperature-uniforming plate is significantly improved.And equably capillary structure 21 is compressed on the internal face that is attached to tabular cylindrical shell 1 by supporter 22, when vacuumizing and use, can not produce the phenomenon of distortion.
When temperature-uniforming plate of the present utility model is used for the heat radiation of heat generating component, the one side correspondence of tabular cylindrical shell 1 is pasted on heat generating component, when the heat generating component operation produces heat, just heat is conducted to tabular cylindrical shell 1 bottom surface, and the working fluid that makes temperature-uniforming plate inside is heated and produces steam, when the liquid vapour phase changes with heat rapidly band and come the heat of tabular cylindrical shell 1 top is carried out from above tabular cylindrical shell 1, locating by assembly (not shown)s such as heating radiators; Make vaporized gas be condensed into liquid on the other hand, utilize the capillary attraction of capillary structure 21, condensed liquid-conducting is flow back into the bottom of tabular cylindrical shell 1, realize the repetitive cycling heat radiation.
Fig. 5 and Fig. 6 are combination synoptic diagram and the assembled sectional view of the utility model second embodiment.As Fig. 5 and shown in Figure 6, heat conductor 2 of the present utility model also can be required according to actual behaviour in service except can be above-mentioned first embodiment, is made up of one or more heat pipes 23.Each heat pipe 23 is processed as flat, and makes its upper and lower faces recline contact respectively at the inwall of tabular cylindrical shell 1, two sides then attach mutually with adjacent heat pipe 23 and contact, and lid 3 are sealed on opening 11 places of tabular cylindrical shell 1 again, and carry out welding and sealing.
In sum, temperature-uniforming plate of the present utility model can effectively improve the many disadvantages that exists in the prior art, improve this temperature-uniforming plate qualification rate during fabrication and increase the stability of using, making production of the present utility model can more progressive, more practical, more meet user institute must, meet the requirement of utility application, file an application according to Patent Law.
The above only is a preferred embodiment of the present utility model, be not so promptly limit claim of the present utility model, the equivalent structure transformation that every utilization the utility model instructions and accompanying drawing content are done, directly or indirectly be used in other relevant technical field, all in like manner be included in the claim of the present utility model.
