METHOD AND DEVICE FOR INDIRECT COOLING OF HEAT SOURCES OF A SYSTEM COMPONENT OF A VISUALIZATION SYSTEM

For increasing the operational reliability of a system component such as a light source unit or a camera control unit of a visualization system, waste heat produced by at least one heat source, which is arranged in an interior of the system component that is closed off to the outside, preferably so as to be air-tight, is transported by a cooling line, which is arranged in the interior and is filled with coolant, and/or by using an internal air circulation effected with appropriately, to a primary heat sink arranged in the interior, and the waste heat is then released from the interior to the outside through the primary heat sink using heat conduction. An efficient cooling of the at least one heat source can be achieved thereby; in addition, the heat source remains largely protected from external ambient influences, in particular it remains protected against dust.
