Cooling of new designed machine

This paper deals with aspiration to offer a special cooling system for enclosed induction machine which operates in explosive environment. This is particularly relevant to electric devices in power plant, or other predisposed applications, where machine arrangement complexity has to be kept to a minimum. A new design was developed to improve heat exchange with a low-pressure drop. A new internal fan was developed to match internal airflow requirements and cooler characteristics and reduce noise. Heat is dissipated much more efficiently due to a redesign in the internal air flow circuit configuration which increases the heat exchange area and air flow.
