PASSIVE COOLING SYSTEM FOR DESKTOP COMPUTERS Russian patent published in 2007 - IPC G06F1/20 F28D15/02 

FIELD: electronics, in particular, cooling of heat-stressed components of electronic devices, including computers, and also in power engineering, in particular, heat pipes.

SUBSTANCE: passive cooling system for desktop computer includes heat pipes with zones of evaporation and condensation with transporting zone located between them, heat interfaces, mated with evaporation and condensation zones, and radiator with vertical ribbing, made in form of wall of system block of computer, connected to which are heat interfaces of condensation zones, each heat pipe being made in form of contour, including evaporation chamber with evaporation zone and reservoir for heat carrier and condenser, including condensation zone, while transport zone is made in form of separate hollow pipelines for steam and liquid with small diameter, connected to evaporation chamber and condenser. Evaporating chamber has cylindrical shape; evaporating chamber has shape of plates; condenser may be made in form of flat serpentine tube; condenser may be made in form of hollow plate having external ribbing; radiator may be additionally provided with two-phased thermal siphons, positioned along the ribs at a distance from each other; ribbing of radiator may be made in form of corrugations; diameter of pipelines for steam and liquid may be made within limits ranging from 1 to 4 mm.

EFFECT: increased efficiency of cooling system, due to decreased thermal resistance of its element when decreasing its dimensions and mass and simplified installation in block of equipment.
