COOLING DEVICE FOR ELECTRONIC ELEMENTS Russian patent published in 2008 - IPC H05K7/20 F28D15/02 

FIELD: electricity.

SUBSTANCE: lowering of total thermal resistance due to using of wrap-around heat-transfer tube as thermal loop, which tube features local positioning of capillary structure in evaporator, is achieved by the fact, that the device consists of heat-transfer tube performed as loop containing flat evaporator with capillary structure, and cooling fan. Flat evaporator has steam and liquid frontal cameras communicating with each other by means of parallel tube bundle acting as condenser connected with external finning. Tube bundle can be connected with evaporator cameras directly or by means of tube collectors. Due to using of flat-shaped evaporator and increase of uniformity of radiator ribs heating by condenser performed according to collector scheme.

EFFECT: decrease in device mass and lowering of noise level due to lowering of required speed of air flow and rotation frequency of cooling fan.
