Abstract
A heat-dissipating cabinet structure may use a heat exchanger mounted at a boundary between an interior cabinet portion and an exterior portion, and heat-generating devices medium-voltage devices (such as high isolation IGBT or diode devices) may be mounted on the interior portion of the heat exchanger. The IGBT or diode devices may be electrically grounded within the cabinet such that contact with the external portion of the heat exchanger does not compromise the required clearance and creepage distances between the device's terminals and its base. Heat dissipating elements (e.g., fins, coils, etc.) may be formed at the outside portion of the heat exchanger to facilitate dissipation. A fan may be used to drive airflow over the exterior portion of the heat exchanger (and its dissipation elements), and the airflow may be directed by an airflow housing.
