Description
Technical field
The utility model relates to a kind of radiator structure, refers to a kind of radiator structure with splendid heat dissipation especially.
Background technology
Existing electronic equipment is high more and speed is fast more along with the usefulness of computing and deal with data, what its inner set electronic building brick was relative will produce higher heat, as can't in real time heat energy being discharged, the lighter will influence operational paradigm weight person and then will cause electronic building brick to burn, so prior art is provided with heat-sink unit and sees through this heat-sink unit in the electronic building brick top described electronic building brick is dispelled the heat, existing radiating subassembly is the most common user mode with the state of radiating fin group or radiator usually, and collocation wears heat pipe to increase the usefulness of heat conduction and heat radiation between the body of radiating subassembly and thermal source.
At present, because heat pipe has heat transfer rate faster, and be widely used in electronic building brick heat radiation field.Heat pipe commonly used comprises the sealed tube shell body with certain vacuum degree, and is provided with the capillary structure that sintering forms and is filled with an amount of working fluid in housing in housing, and this heat pipe one end is an evaporation ends and the other end is a condensation end.When the heat pipe evaporation ends is heated, the hydraulic fluid carburation by evaporation, steam condenses into liquid after condensation end is emitted heat flowing under the small pressure reduction, and described liquid is back to the heat pipe evaporation ends by the capillary pressure difference of capillary structure generation, and from making heat reach condensation end rapidly by the heat pipe evaporation ends.Yet, the service behaviour of heat pipe is subjected to influencing of capillary pressure difference and the two factor of backflow resistance, this two factor changes along with the size of the capillary porosity of capillary structure, when the capillary porosity hour, it is poor that it has big capillary pressure, can drive coagulating liq enters in the capillary structure and refluxes to evaporation ends, the frictional force and the viscous force increase that reduce to make the working fluid backflow of capillary porosity but then, be that hydraulic fluid backflow resistance increases, cause the hydraulic fluid back-flow velocity slow, easily make heat pipe in evaporation ends generation dry combustion method phenomenon, and when the capillary porosity is big, hydraulic fluid is subjected to less backflow resistance, yet, the capillary pressure difference that makes coagulating liq suck capillary structure reduces thereupon, reduce the hydraulic fluid capacity of returns, also can make heat pipe in evaporation ends generation dry combustion method phenomenon, and system is sintered in the heat pipe inwall to form described capillary structure with the mode that copper powders may sees through powder metallurgy because of the inside heat pipe capillary structure, also has hole because of capillary structure, conjugation is not good to each other, copper powders may is often come off by external force bending to intersperse among inside heat pipe to make heat pipe for thermal conductivity usefulness reduce because of heat pipe, the heat energy that central processor produced among the high power so the capillary structure of conventional heat pipe can't have been loaded.
According to the shortcoming known to above-mentioned, the personage who is familiar with this skill adopts the artificial diamond material with high thermal conductivity coefficient to be used as increasing the structural material of heat radiation and heat conduction efficiency, the heat conductivity of carbonado is up to 2300 (W/m.K), heat conductivity 401 (W/m.K) compared to copper, much higher, can effectively promote radiating efficiency so see through the made radiator structure system of described artificial diamond material, because of being subjected to artificial diamond material deposition and all condition elements of manufacture method restricted down, so cost is comparatively expensive, for example using chemical vapour deposition technique that the workpiece of desire deposition is carried out artificial diamond coating criticizes and covers, the workpiece size of desire deposition and material melting point are all the ㄧ of restricted condition, so then can't the artificial diamond coating of coating at the material of relatively large and low melting point, so need make graininess or Powdered and other dissimilar materials of arranging in pairs or groups is mixed together sintering and uses, but described artificial diamond material and other dissimilar materials conjugation are not good, the mode that for example sees through powder metallurgy makes described artificial diamond material combine with metal powder sintered, and last artificial diamond material also can not come off because conjugation is not good; So prior art has following shortcoming:
1. conjugation is not good;
2. cost is higher;
3. heat conduction efficiency is not good;
4. the rapidoprint confined condition is more.
