High-performance cooling fans

The increasing construction of large load circuits for drives and controllers results in the use of larger and higher performance electronic assemblies like IGBTs and similar devices. In these performance classes, efficient heating is only possible through forced convection making use of fan units or liquid coolers.

Fischer Elektronik is expanding its product range in the area of high-performance fan units with the LA 18 and LA 22. Measuring 184 x 93 mm and 243 x 120 mm, the fan systems have a flow-optimised hollow rib geometry allowing them to achieve particularly effective heat conduction in conjunction with axial fan motors.

The semiconductor surfaces are arranged so as to minimise heat transmission resistance and optimise component contact. A pre-chamber construction coordinated with the hollow-rib geometry for the units also reduces heat resistance (laminar airflow) and lowers fan noises.
