FIELD: cooling.
SUBSTANCE: invention relates to cooling devices and can be used in electric power elements with high heat release. Disclosed cooling device includes housing 7, dielectric plate 2, mounting platform 3 with inner hollow shape at cooled element 1 (device), radial fins 4 with heat exchange intensifiers, fan 8 installed in upper part of housing. Between radial fins 4 are provided removable chamber 10 with liquid low-boiling coolant, wherein radial fins 4 are components of stationary 21 and removable fins 22 and each removable chamber 10 is provided with a viewing window 16, filler 11 and drain neck portion 14 with sealed screw cap 12, outlet tube 13 and side flanges 18 with holes for bolting. In said stationary radial fins 21 are integrally formed with mounting platform and on ends of each stationary fin, a groove for installing removable radial fins 22 and holes 18 for bolting stationary edges and two removable side flanges of adjacent chambers.
EFFECT: technical result is improving efficiency of device by means of heat exchange intensification, increasing device reliability.
