Abstract: An exemplary electric apparatus includes a fan for generating a first airflow, a component space includes a secondary electric component, and a housing. In order to obtain efficient cooling solution one or more walls separate the component space including the secondary electric component from the first cooling element for preventing the first airflow from entering the component space. A second cooling element has a first end in the component space and a second end located outside of the component space for dissipating heat received from the secondary electric component to the first airflow.
