Along with the LED technology rapid development, caloric value and the density of heat flow rate of LED increase considerably, and at present, the density of heat flow rate of LED device is up to 400W/cm
2And the density of heat flow rate of general free convection cooling heat dissipation is no more than 0.8W/cm
2, the density of heat flow rate of wind-cooling heat dissipating is no more than 10W/cm
2, have only the liquid cooling of employing and hot pipe technique can make the density of heat flow rate of heat radiation reach 100W/cm
2Reaching and surpassing this density of heat flow rate value is a global difficult problem on the heat dissipation technology.Second difficulty is that the heat-dissipating space that can leave device for also had been subjected to huge restriction after the device integrated level improved, and the technical scheme that can adopt is restricted, and has more increased difficulty.Because what electronic device mainly adopted is semi-conducting material, therefore the temperature resistant capability of device is more weak, for example for the LED device, the obviously decline of the efficient of device, the lost of life, color change when temperature raises, particularly when the device nodes temperature was higher than about 130 ℃, device will be burnt out.Usually the liquid cooling system volume is big, and itself there is potential safety hazard in the liquid cooling technology, in case revealing appears in liquid cooling system, will cause LED to damage.The hot pipe technique heat transfer efficiency is very high, but the manufacture craft of general heat pipe is very complicated, and the contact area of general heat pipe such as circular heat pipe and electronic equipment heating face is very little, causes equivalent thermal resistance big, makes to use to be very limited.
Summary of the invention
The present invention is directed to the defective or the deficiency that exist in the prior art, a kind of New LED and high-power radiating element radiator are provided, the radiator that forms with flat-plate heat pipe has radiating efficiency height, advantage of simple technology to electronic equipment dissipating heat.
Technical scheme of the present invention is as follows:
A kind of New LED and high-power radiating element radiator, it is characterized in that: comprise flat-plate heat pipe, described flat-plate heat pipe is that metal material is through extruding or stamping forming two via-hole array slab constructions that are arranged side by side more than reaching, the equivalent diameter of described through hole is 0.5mm-3mm, is filled with the sealed at both ends encapsulation of liquid working substance and flat-plate heat pipe in the described through hole; The evaporation section of flat-plate heat pipe contacts with the heating face face of LED and high-power radiating element, and its condensation segment dispels the heat by thermal component.
The some little fin that has extrusion modling on the described through-hole wall with augmentation of heat transfer effect.
The distance of adjacent two little fins is 0.01mm-0.5mm, and the height of little fin is 0.03mm-1.5mm.

Described heat dissipation metal parts are outer fin, and described outer fin is equipped with by aluminium or copper.
The sealed at both ends encapsulation of described through hole forms the micro heat pipe that works alone.
Described flat-plate heat pipe bends to " L " type or similar " L " type; The bottom of described " L " type is an evaporation section, and the side is a condensation segment.
Described flat-plate heat pipe bends to " U " type or similar " U " type; The bottom of described " U " type is an evaporation section, and both sides are condensation segment.
Technique effect of the present invention is as follows:
New LED of the present invention and high-power radiating element radiator, form via-hole array with the through hole of equivalent diameter and constitute flat-plate heat pipe to form specific radiator with the particular range that adapts with factors such as the condition of work of LED and high-power radiating element and heat generation characteristics, the evaporation section of flat-plate heat pipe is contacted with the heating face face of LED and high-power radiating element, and its condensation segment dispels the heat by thermal component.Filling liquid working medium forms micro heat pipe in the through hole, forms the heat pipe effect naturally.Owing to have the high advantage of hot pipe technique heat transfer efficiency, simultaneously again because be flat-plate heat pipe, its evaporation section contacts with the heating face face of LED and high-power radiating element, make that the contact area of heating face of flat-plate heat pipe and LED and high-power radiating element can be very big, so make that the heat conduction equivalent thermal resistance is very little, improved heat transfer efficiency, also improved simultaneously the radiating efficiency of LED and high-power radiating element, the contact area of heating face that has overcome existing circular heat pipe and LED and high-power radiating element is little, the shortcoming that the heat conduction equivalent resistance is big, and owing to be extrusion modling, technology is simple, when having saved existing heat pipe and making such as technology such as capillary wick material preparation.Consider heat generation characteristic and the LED and the architectural characteristics such as high-power radiating element installation environment, condition and environment for use of the heating face of LED and high-power radiating element, the equivalent diameter that through hole is set is 0.5mm-3mm, in through hole, be filled with liquid working substance and form micro heat pipe, both strengthen the exchange capability of heat of liquid working substance, and can effectively reduce contact heat resistance again.
Have the exchange capability of heat that some little fins can further strengthen liquid working substance on the through-hole wall, and has capillary force between little fin that is provided with in the through hole and the through-hole wall, also can produce capillary force if distance is suitable between little fin and the little fin, the formation of capillary force has promoted flowing of working medium, also helps the enhance heat transfer ability.
The distance that adjacent two little fins are set is 0.01mm-0.5mm, and the height of little fin is 0.03mm-1.5mm, not only very high heat-transfer capability can be arranged, and significantly strengthens mechanical properties such as the bending resistance of flat-plate heat pipe own, heat resistanceheat resistant.
The size of little fin and structure are suitable for forming along the based on capillary slot of through hole length direction trend with through-hole wall, can produce high-intensity phase-change heat transfer.
The groove width that based on capillary slot is set is 0.01mm-0.4mm, groove depth is 0.03mm-0.7mm, the kind of liquid working substance cooperates the size and the structure of suitable based on capillary slot, the density of heat flow rate that forms in the time of can strengthening the heat radiation of LED and high-power radiating element, increasing substantially heat transfer efficiency, thereby make that LED and high-power radiating element are cooled off rapidly.
The sealed at both ends encapsulation of through hole forms the micro heat pipe that works alone, like this, flat-plate heat pipe contain two and more than join side by side and micro heat pipe that work alone, can not influence other micro heat pipe work even certain micro heat pipe is damaged as take place revealing yet, and help security maintenance.
Thermal component is that the outside heat dissipation metal parts of installing of flat-plate heat pipe condensation segment carry out air cooling, the heat dissipation metal parts are outer fin etc., can augmentation of heat transfer, accelerate flat-plate heat pipe in the condensation segment heat release, make the quick heat release condensation of liquid working substance flow back to the evaporation section of flat-plate heat pipe.
Flat-plate heat pipe bends to " L " type or similar " L " type, and flat-plate heat pipe bends to " U " type or similar " U " type, because being nature, this flat-plate heat pipe forms the heat pipe effect, with the flat-plate heat pipe brake forming, as LED and high-power radiating element radiator, liquid working substance heat absorption back carburation by evaporation in its evaporation section, naturally travel up to condensation segment, condensation segment heat release liquefaction, and rely on gravity or capillary force effect to flow back to evaporation section downwards, automatically finish circulation, this structure is more conducive to heat exchange, reaches the quick cooling purpose of electronic equipment.
