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.
Claims9
An electric apparatus, comprising:
- an inlet and an outlet for passing a first airflow generated by a fan through the apparatus;
- a first cooling element for receiving heat generated by a primary electric component and for dissipating heat into the first airflow;
- a component space including a secondary electric component;
- a housing that encloses the first cooling element, the secondary electric component, and the component space;
- one or more walls separating the component space containing the secondary electric component from the first cooling element and preventing the first airflow from entering the component space, and
- a second cooling element having a first end in the component space, which first end is thermally connected to the secondary electric component to receive heat generated by the secondary electric component, and a second end located outside of the component space to dissipate heat received from the secondary electric component to the first airflow,
- wherein the first end of the second cooling element is provided with fins, and the second end of the second cooling element is provided with fins.
