Description
Technical field
The utility model system is relevant for a kind of heat-sink unit; Especially refer to a kind of do not destroy heat-sink unit itself and fixed structure is set on it; One preferable locking mode is provided, so prevent that effectively its inner cavity chamber of this heat-sink unit from producing the fixed structure that seepage influences the heat-sink unit of hot transfer efficiency.
Background technology
With existing electronic equipment gradually with frivolous as the demand of bragging about, so various elements all must be dwindled its size thereupon, the thermal change that produces but the dimension shrinks of electronic equipment is followed becomes the major obstacle of electronic equipment and system enhancement performance.The semiconductor dimensions that no matter forms electronic component is constantly dwindled, and still requires to increase performance constantly.
When semiconductor dimensions is dwindled; Heat flux increases as a result; It only is all increases of heat that the challenge that heat flux increase cause is cooled off product surpasses, overheated because the increase of heat flux causes at different time and the meeting of different length size, possibly cause electronic failure or damage.
And temperature-uniforming plate system uses for the heat conduction of a kind of face in a big way and face, and it is different from the point-to-point heat exchange pattern of heat pipe, and is applicable to the comparatively narrow part use in space.
Temperature-uniforming plate has a heating surface and a cryosurface and a vacuum chamber and is filled with working fluid; Have a plurality of support columns and capillary structure in this vacuum chamber; Said support column connects the heating surface and the cryosurface of this temperature-uniforming plate and supports this vacuum chamber; Temperature-uniforming plate system is sticked through this heating surface and thermal source, and the cryosurface of this temperature-uniforming plate opposite side then is connected the conduction heat with another heat abstractor, and this working fluid in the heating surface place life of heat of adsorption volume production evaporate the working fluid that converts gaseous state to; This gaseous working fluid produces condensation in this cryosurface place; Convert liquid state into, the working fluid of this liquid state is back to heating surface through the capillary structure of chamber interior, and working fluid forms vapour-liquid circulation conduction heat in this chamber.
Known system uses a temperature-uniforming plate and a substrate bonded and pass through the heat of the heater element on this substrate of temperature-uniforming plate conduction; Known technology mainly lies in the position that temperature-uniforming plate is avoided this chamber; Promptly the four coupling places of this temperature-uniforming plate respectively wear one have an internal screw thread the copper post, substrate this temperature-uniforming plate position system that the copper post is set is relatively offered at least one hole, wears said copper post through a screw lock element simultaneously with the mode of screw lock again and hole is fixed in this temperature-uniforming plate on this substrate; But this fixed form is arranged at the four coupling places of this temperature-uniforming plate because of the copper post; Far away with this heater element distance, the fixing back of this temperature-uniforming plate can't fit tightly with heater element, and then produces thermal chocking; For improving the aforementioned problem that can't fit tightly; Then the dealer is arranged at the adjacent at the position that this temperature-uniforming plate and heater element be sticked with the direct correspondence of copper post, so the position that temperature-uniforming plate has chamber is directly run through in said copper post system, though tightness prevents that thermal chocking from producing can increase assembling the time; But the chamber of this temperature-uniforming plate loses air-tightness after receiving said copper post to run through destruction; Its chamber interior no longer has vacuum state, and destroys this chamber because of the copper post runs through, and then the flow path of the working fluid of its inside possibly therefore interruptedly cause hot transfer efficiency to reduce; Even seriously also possibly produce leakage, and then make this temperature-uniforming plate lose heat biography effectiveness; So known technology has disadvantage:
1. be prone to produce thermal chocking;
2. hot transfer efficiency reduces.
