HEAT RADIATION SYSTEM Russian patent published in 2007 - IPC H01L23/40 

FIELD: heat radiation systems.

SUBSTANCE: proposed heat radiation system has fastening plate for securing six change-over devices to heat sink which are set in line on printed-circuit board. The latter is made of single metal plate and has base section elongated in direction of disposition of change-over devices and three sections holding down the device which are disposed on one end of base section, spaced apart, and joined through junction parts to base section; section holding down the device is wide enough in longitudinal direction of base section to hold down two coupled change-over devices and has hole to receive screw in center of its longitudinal width for mounting change-over device between section holding down the device and heat sink and for screwing change-over device to heat sink; jointing part is made so that its width is smaller than that of section holding down the device so as to allow section holding down the device to obliquely displace relative to heat sink when change-over device is being mounted and its holding down section is screwed to heat sink.

EFFECT: improved mechanical design of heat radiation system.
