Description
Technical field
The utility model relates to a kind of slim hot plate structure, relate in particular to a kind of can be on demand arbitrarily configuration and having conduct heat to the far-end effect and promote the characteristic of working fluid cycles speed etc., effectively to reach the slim hot plate structure of excellent radiating effect.
Background technology
Along with making rapid progress of science and technology, the power and the usefulness of electronic component promote day by day, when operation, also produce more heat jointly; If these heats are failed timely dissipation and gone out and be accumulated in the inside of said electronic component, will cause said temperature of electronic component to raise and influence its usefulness, even severe patient will cause said electronic component damage.So industry is in order effectively to solve the problem of electronic element radiating; Just propose to have the heat pipe (Heat pipe) of preferable temperature-uniforming plate of heat conduction efficiency (Vapor chamber) and slimming successively; And it can be done matched combined with radiator, with effective solution heat dissipation problem of present stage.
The heat pipe structure of slimming at present; Be that hollow space in bigbore heat pipe is inserted metal dust; And the mode that sees through sintering forms the capillary structure of a ring-type at the inwall of said slim heat pipe; Then said slim heat pipe is vacuumized and fill working fluid, the heat pipe structure with the achievement slimming is flattened in sealing at last; But because the heat pipe of slimming of the prior art is set to the capillary structure of whole loop because of its inboard; When flattening thinning, can cause the too narrow or obstruction of its inner steam channel because of the extrusion of said ring-type capillary, influence liquid-gas phase transitionization and make heat conduction efficiency clear.
In addition; The heat pipe of said slimming of the prior art is fixedly caliber on making; Can't according to Demand Design shape that the user desired and caliber size (as an end big footpath one end path or the isometrical centre of two ends gradually greatly or gradually thin); And because of the capillary structure in the heat pipe is the setting of stationary uniformity ring shape, cause when the shape of said slim heat pipe being made change (like crooked or recessed folding shape), can make slim inside heat pipe ring-type capillary structure (being the metal dust of sintering) receive the bending extruding; And cause the capillary structure of said slim heat pipe to come off in extruding place, significantly reduce so make the heat of said slim heat pipe pass usefulness; In addition, because said slimming heat pipe is the capillary structure that only has ring-type, does not have other and can change design; Cause it when flattening thinning; Also the lamination up and down because of said ring-type capillary structure changes, and causes thickness to increase and can't heat pipe be flattened be thinned to minimum level, and the thinning effect is limited.
And temperature-uniforming plate of the prior art (vapor chamber) is to comprise the housing that is square type shape and the capillary structure of enclosure interior chamber wall thereof; And said enclosure interior is filled with working fluid; And a side of said housing (being evaporating area) is to be sticked to go up the absorption heat that said heater element produced at a heater element (like central processing unit, north and south bridge wafer); Make liquid working fluid convert steam state in the evaporating area generation evaporation of said housing; Heat is conducted to the condensing zone (being condensing zone) of said housing; The working fluid of said steam state is condensed into liquid state after condensing zone is cooled off, the working fluid of said liquid state sees through gravity or capillary structure again and is back to the circulation of evaporating area continuation vapour-liquid, effectively to reach the effect of temperature uniforming heat radiation.
Though temperature-uniforming plate of the prior art can reach the effect of samming, extend another problem, promptly the heat transfer type of temperature-uniforming plate is after attaching heat by the one of which side draught; Liquid-gas phase transition conduction opposite side by the working fluid in the chamber; In other words, be exactly temperature-uniforming plate only be to conduct to relative opposite side area reaching equal temp effect by lateral area absorption heat, but can't have heat transfer type as heat pipe; Can the heat of absorption be conducted to far-end dispels the heat; Therefore, make temperature-uniforming plate only limit to be fit to use large-area uniform heat conduction, be applied to far-end heat conduction and be not suitable for bringing.
The above, prior art has following shortcoming:
1, slimming heat pipe thickness is restricted, and can't change caliber, capillary structure and shape thereof arbitrarily;
2, temperature-uniforming plate can't be with heat transferred to far-end, and weight is heavier;
3, increase cost.
Therefore, how to solve above-mentioned prior art problems and disappearance, the creator who is this case desires most ardently the direction place that research improves with the relevant manufacturer that is engaged in the industry.
