Description
Technical field
The present invention relates to a kind of flat-plate heat pipe manufacture method, particularly relate to one and can reach flat-plate heat pipe
Slimming and the flat-plate heat pipe after guaranteeing slimming still have the flat-plate heat pipe system of unimpeded steam channel
Make method.
Background technology
Existing electronic mobile device is frivolous for moving towards towards being, and modern electronic mobile device is the lightest
Its operation efficiency thin promotes the most therewith, but the lifting and integral thickness with operation efficiency reduces in it
The space of portion's holding electronic element is the most limited, when operation efficiency improves, and relative electronics unit
During part computing, produced heat increases the most therewith, therefore needs heat dissipation element to be assisted each electronics unit
The heat radiation work of part, again because of this electronic mobile device because under conditions of thinning, its inner space is
The narrowest it is difficult to arrange the heat dissipation elements such as fan, therefore is only capable of arranging copper foil or aluminum slice as increasing
Big area of dissipation uses, but the lifting for heat dissipation is the most not enough.
Take slimming because of entirety when heat pipe or temperature-uniforming plate are made slimming by prior art, cause
Thin type heat pipe is because filling out powder sintering difficulty after slimming, it is difficult to realize the structure of extremely thin type, or fill out powder
When being pressed into flat structure after sintering, inside heat pipe sintered powder or other capillary structure (grids
Body or corpus fibrosum) it is squeezed and destroys and anergy.
It addition, existing temperature-uniforming plate is more micro-slimming, the supporting construction within omission makes temperature-uniforming plate
Bleeding after sealing, internal chamber is easily deformed, therefore existing slimming heat pipe and the steaming within temperature-uniforming plate
Vapour passage is easily diminished by compression or even without steam channel, the internal overall steam-condensate circulating of impact
Efficiency, therefore the steam-condensate circulating structure how improveing the temperature-uniforming plate after slimming and inside heat pipe is and works as
The target must improved down.

Body or grid body or the combination of corpus fibrosum.
Described first and second plate body is carried out closely sealed edge sealing engaged by diffusion or ultrasound welding or point
Weldering any of which.
Described capillary structure body is selected to be fixed on aforementioned first and second plate body any of which and is connect by diffusion
Close or ultrasound welds or spot welding any of which mode is carried out.
Capillary structure in described flat tubular body is arranged between this first and second plate body to be adopted in pairs
Arrange, and this capillary structure and first and second plate body define at least one steam channel jointly.
Still have complete by the flat-plate heat pipe after flat-plate heat pipe manufacturer's decree slimming of the present invention
Steam channel, thereby ensures that the flat-plate heat pipe internal chamber energy of slimming can smooth and easy holding steam-condensate circulating
Person.
