摘要：

The purpose of this: study is the enhancement of cooling of high heat flux power devices such as a thyrista by a thermosyphon system, The thermosyphon used boiling and condensation of inert dielectric fluorocarbon (FC-72), Boiling occurred from a multiple chimney heat transfer structure, A boiling chamber is connected to the condenser by a double tube, with the inner tube carrying the condensed liquid and the outer annulus carrying vapor, Using the experimental model of a thermosyphon, heat flux capacity was enhanced by increasing the how tube height H-o, boiling chamber height H-h, and condenser liquid level H-l. High heat flux capacity was achieved with H-o > 8 cm, H-h > 10 cm, and H-l > H-o, using chimney heat transfer structure with a channel width of 3 mm, The thermosyphon system was able to cool a maximum heat Aux of 3 kW per device.
