THERMAL PIPE WITH FORCED LIQUID CIRCULATION AND THERMAL PIPE FOR COOLING NOTEBOOKS Russian patent published in 2006 - IPC H05K7/20 G06F1/20 

FIELD: power engineering, possible use for transferring significant heat flows from device to device, from environment to device or vice versa, from device to environment, in particular, can be used for cooling heat-generating elements of computer.

SUBSTANCE: between heat-generating zone and liquid pipeline a wall is positioned made of fine-pored material or capillary portion of pipeline, lower portion of liquid pipeline is provided with device for periodic or pulse heating of liquid incoming into pipeline through wall, while shape and dimensions of section of liquid pipeline provide for possible movement of steam-liquid mixture in the mode of "implement" boiling, when portions of liquid move along pipeline together with steam plugs without division onto separate steam and liquid flows. Device allows adjustable return of liquid from condensation zone to one or more boiling zones oppositely to gravitation forces along pipeline without utilization of dynamic equipment, only due to periodic measured losses of thermal energy. Utilization of aforementioned construction of heat-generating portion of thermal pipe (radiator), meant for mobile computers, allows to combine radiator with lower body lid of mobile computer and provide for forced influx of liquid from radiator to heat-taking portions of thermal pipe for any position of computer in space.

EFFECT: higher efficiency, lower costs.
