Description of drawings
Accompanying drawing 1 is the utility model gas-liquid two-phase separation type gravity assisted heat pipe heat spreader structures schematic diagram;
Accompanying drawing 2 is that gas-liquid two-phase separation type gravity assisted heat pipe radiator shown in the accompanying drawing 1 is along the cutaway view of A-A line;
Wherein: 1, evaporimeter 2, Heat Conduction Material; 3, tedge; 4, condenser Left-wing Federation case; 5, condenser radiating tube; 6, radiating fin; 7, condenser; 8, the right header of condenser; 9, down-comer; 10, thermal source; 11, thermally conductive grease; 12, hot conducting surface; 13, working fluid.
The specific embodiment
Referring to accompanying drawing 1～2, this gas-liquid two-phase separation type gravity assisted heat pipe radiator comprises an evaporimeter 1, condenser 7, tedge 3, a down-comer 9.The right header 8 of condenser 7 condenser Left-wing Federation casees 4, condenser and be arranged on two radiating tubes 5 between two headers, this radiating tube 5 is horizontally disposed with and is parallel to each other, the left and right both ends of two radiating tubes 5 are connected with the right header 8 of condenser Left-wing Federation case 4 and condenser respectively, the outer tube wall of radiating tube 5 is provided with a plurality of radiating fins 6, radiating fin 6 on each root radiating tube 5 is evenly distributed on the outer wall of pipe, generally good in order to make that radiating fin 6 contacts with radiating tube 5 heat conduction, radiating fin 6 is welded on radiating tube 5 outer walls by welding material of metal.Evaporimeter 1 is positioned at below of whole device, and evaporimeter 1 top links to each other with condenser Left-wing Federation case 4 bottoms by tedge 3, has realized being connected with evaporimeter by down-comer 9 in header 8 bottoms, the condenser right side.Evaporimeter 1, tedge 3, condenser 7, down-comer 9 are formed the vapour-liquid loop of circulation, are filled with working fluid 13 in this vapour-liquid loop, and working fluid 13 can be water or methyl alcohol or acetone.
The bottom of evaporimeter 1 has one to be used for the hot conducting surface 12 that contacts with thermal source to be dispelled the heat.In order to reduce thermal contact resistance herein, scribble thermally conductive grease 11 at the hot conducting surface 12 of thermal source 10 and evaporimeter 1.
