The increasing construction of big load circuits for drives and controls lead to a use of always bigger and more powerful electronic devices such as IGBT and similar. In those power classes a heat dissipation is only possible by forced convection by means of cooling aggregates or fluid heatsinks. A cooling aggregate consists of an assembly of fins, lamellas or similar, suitable geometries for heat exchanging surfaces and one or more fans. The electric devices mounted on the cooling aggregate bring the developed dissipation loss as a thermal output into the construct cooling aggregate by means of heat conduction. The existing fan produces an air flow which is navigated to the internal structure in a cooling aggregate and dissipates the inserted heat to the outside. Different conceptions for a cooling aggregate are the high capacity-, segment- and miniature cooling aggregates with different structures of the heat exchanging surfaces which are equipped with axial-, diagonal or radial fans in dependence to the overall conception. The offered concepts from Fischer Elektronik are based on the cooling aggregate itself and the resulting versatile modification possibilities in size, design and type of fan.
