Background technology
Known electronic installation, as central processing unit (Central Processing Unit, CPU), (Graphic processing Unit GPU) and laser diode (Laser Diode) etc., can produce a large amount of heats to painting processor in its operating process.If in operating process, heat can't be fully from similar above-mentioned high power density equipment (High Power Density Device, HPDD) in heat radiation fully, will influence its operating efficiency.For example too high temperature can cause the malfunction or the fault of equipment.Therefore, can remove too high heat will help equipment can bring into play its normal function in the use.
General high power density equipment is the mode by heat conduction (conduction), and the heat conduction of its generation is extremely extraneous.And, must reduce the thermal resistance of conducting heat in order to remove more heat, a kind of method wherein is to utilize radiating fin to increase high power density equipment and extraneous efficiently radiates heat area.
See also shown in Figure 1ly, it is the known heat radiation fin structure 101 that is arranged on the high power density equipment 103.The heat that this high power density equipment 103 is produced can conduct to this heat radiation fin structure 101, by this heat radiation fin structure 101 heat is reached in the atmosphere again.Wherein, the conductive surface area of this heat radiation fin structure 101 is greater than this high power density equipment 103, therefore by increasing effective area that this heat radiation fin structure 101 conducts heat reducing the thermal resistance between between this high power density equipment 103 and atmosphere, and then increase the diffuser efficiency of heat.At last, heat utilization free convection (natural convection) or cooperation fan reach the atmosphere from this heat radiation fin structure 101 in the mode of forced convertion (forced convection).
But the material that is used to make heat radiation fin structure has inborn resistance for heat mobile.Therefore the bottom of heat radiation fin structure will produce uneven temperature branch, thereby reduce the radiating efficiency of heat radiation fin structure.
See also shown in Fig. 2 A, heat radiation fin structure 201 has uneven temperature branch in its bottom, different arrow length shows the flow regime of these heat radiation fin structure 201 heat, and the fin that is positioned at the outside that wherein has short arrow has flowing of less heat than being positioned at inboard fin (long arrow).That is the inboard fin of this heat radiation fin structure 201 has preferable heat dissipation than outside fin, therefore produces uneven temperature branch in the bottom of this heat radiation fin structure 201.See also shown in Fig. 2 B, heat radiation fin structure 205 has even temperature branch in its bottom.Wherein the arrow length of equal length shows that the interior outer-finned of this heat radiation fin structure 205 has uniform hot-fluid situation, and its heat radiation fin structure 201 with Fig. 2 A is different.The inside and outside lateral fin sheet of this heat radiation fin structure 205 has identical radiating effect.
Therefore, in order to increase the radiating effect of radiating fin, even temperature branch must be arranged at the radiating fin bottom, wherein a kind of important method is to use thermal diffuser (heat spreader), make the radiating fin bottom have the temperature of even branch, wherein thermal diffuser is placed between high power density equipment and the radiating fin device, with the heat uniforming that the heat radiation fin structure bottom is absorbed.
See also shown in Fig. 3 A, high power density equipment 301 is to be installed on the build-in plate 303, and heat radiation fin structure 305 is settled this high power density equipment 301 of contact.Wherein heat is to conduct to heat radiation fin structure 305 by high power density equipment 301, and after heat reaches in the ambient atmosphere by heat radiation fin structure 305 again.

Thermal diffuser is made by low thermal resistance material, for example copper or aluminium etc.The material of light weight has higher heat conductivity, and (Chemical Vapor Deposition, film CVD) also often are used for making thermal diffuser as Graphite pad or chemical vapour deposition (CVD).But the material expensive of above-mentioned high thermal conductivity, and substantially compare with the thermal diffuser of aluminium or copper, the performance of thermal diffuser can't be promoted.
See also shown in Figure 4ly, thermal diffuser 401 is a steam cavity (vapor chamber).This thermal diffuser 401 is to be arranged between high power density equipment 403 and the heat radiation fin structure 405.This thermal diffuser 401 has two surfaces, and wherein a surface 407 contacts with this heat radiation fin structure 405, and another surperficial 409 contacts with this high power density equipment 403.This thermal diffuser 401 has liner 411 in its inside.Liquid on another surface 409 in order to absorb the heat that is produced from this high power density equipment 403, treat liquid evaporation after, the steam that it produced recharges the vacuum section of this thermal diffuser.And when steam contacts this surface 407, transfer heat to this heat radiation fin structure 405, and after treating vapor condenses, utilize gravity or capillarity to be back to another surface 409.
But the heat transfer property energy of known thermal diffuser in the steam cavity, be subject to assembly (nucleation) characteristic of vapor/liquid, and between metal surface and liquid level, and the influence of the interfacial resistance between between metal surface and steam (interface resistance).Therefore, known employed thermal diffuser can't reach effective radiating effect.
