The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: see also shown in Fig. 1,2, a kind of flat heat pipe that has one-sided to netted capillary structure,
Described flat heat pipe A comprises:
One flat type body 10, its pipe shaft section are that flat hollow and defining is formed with at interval and is two plane diapires 11 relatively and is linked to two sidewalls 12 that are the arc surface shape between described two diapires 11;
One is one-sided to netted capillary structure 20, is sintered to fix in a wherein diapire 11 affiliated area scopes of described flat type body 10 and is one-sided to setting.
As shown in Figure 3, the diapire 11 and the sidewall 12 of described flat type body 10 are formed with channel form capillary structure 30, described channel form capillary structure 30 is to extend the extension groove that forms are provided with along described flat type body 10, so that described one-sidedly be sintered to fix in described channel form capillary structure 30 to netted capillary structure 20.
As shown in Figure 4, the described one-sided scope that is provided with to netted capillary structure 20 is for extending to the Zone Full of described two sidewalls, 12 affiliated area scopes.
As shown in Figure 5, the described one-sided scope that is provided with to netted capillary structure 20 is for extending to the regional area of described two sidewalls, 12 affiliated area scopes.
Shown in Fig. 6,7, described one-sidedly have the disconnected type sintering portion 40 of a plurality of convexs spaced apart to netted capillary structure 20, the disconnected type sintering portion 40 of described convex protrudes out and is the spiculation setting towards diapire 11 directions of described flat type body 10, so that describedly one-sidedly be able to be sintered to fix with described diapire 11 by the disconnected type sintering portion 40 of each described convex to netted capillary structure 20; Setting by the disconnected type sintering portion 40 of described convex, mainly can utilize the disconnected type sintering portion 40 of described convex to be 11 little somes contact conditions of diapire of spiculation and described flat type body 10, make that the two sintering contact site is easier to be obtained preferable sintering by melting and close effect admittedly, can promote described one-sided to the two sintering syncretizing effect of netted capillary structure 20 and heat pipe 10 diapires 11 so that it is in conjunction with firm more (be meant the state when the disconnected type sintering portion 40 of this convex is not set for).
Again as shown in Figure 8, be described one-sided another example that is sintered to fix by the disconnected type sintering portion 40 of each described convex and described diapire 11 formed channel form capillary structures 30 to netted capillary structure 20.
Form design by said structure, see also shown in Fig. 1,2, the core design of the flat heat pipe A of the utility model, mainly be described flat type body 10 wherein a diapire 11 affiliated area scopes be sintered to fix one-sided technical characterstic to netted capillary structure 20; Whereby, because in the heat pipe processing procedure, if finished product is flat heat pipe, usually still suppressed and formed by the pipe stock, therefore, since described one-sided only be one-sided to netted capillary structure 20 to setting, so be set as in the process of flat type section shape in described pipe stock pressure, the described one-sided degree that stress deformations takes place to netted capillary structure 20 can be reduced to minimum, is guaranteed describedly one-sidedly still can keep intimate-association state and do not have the problem of disengagement, warpage between netted capillary structure 20 and described flat type body 10 diapires 11; And described one-sided to netted capillary structure 20 for described flat heat pipe A practical application, though be one-sided to setting, but can reach condensate liquid backflow conveying effect ability is identical with existing ring section in fact, because when flat heat pipe A uses, normally be attached on the source of heat release (as CPU) with its diapire 11 down, so its condensate liquid can flow naturally and focus on this diapire 11 zones, therefore corresponding described one-sided to netted capillary structure 20, just can give full play to its capillary guide function, reach the purpose of quickening condensate liquid backflow transfer efficiency.
And for example shown in Figure 9, for described one-sided to the stacking example of putting of netted capillary structure 20 plural numbers; Because the heat conduction of heat pipe running, the flow direction of its steam is opposite with condensate liquid backflow direction, and flowing rapidly of steam, the back-flow velocity of condensate liquid is then relatively slowly many, therefore the condensate liquid surface is subjected to the high-speed reverse air blast effect of vapor stream easily and produces water liquid splash phenomena, and this can produce interference effect to the backflow of condensate liquid; So, utilize described one-sided setting to netted capillary structure 20, can separate the steam flowing space and condensate liquid backflow space, effectively prevent the generation of problems such as described water liquid splash phenomena; And stacking put one-sided to netted capillary structure 20 of plural number shown in this example compared the one-sided of single-layer type and can be obtained better separation effect to netted capillary structure 20.
The producible new effect of the utility model is as follows:
1, by the described one-sided structural design that has additional the disconnected type sintering portion of described convex to netted capillary structure, so can utilize the disconnected type sintering portion of described convex can promote characteristics with heat pipe diapire sintering syncretizing effect so that described one-sided sintering to netted capillary structure and heat pipe inwall close state admittedly can be firm more when the disconnected type sintering portion of this convex is not set, strengthen.
2, by described one-sided to netted capillary structure for the plural number stacking structural design of putting, it can obtain better separation effect to netted capillary structure structure than the one-sided of single-layer type, accurately separate the flat inside heat pipe steam flowing space and condensate liquid backflow space the two, reach the generation of effectively anti-sealing liquid splash phenomena, the backflow that makes condensate liquid is effect more smoothly.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed within the protection domain of the present utility model.
