Forced Air <strong>Cooling</strong> System<br />
Pros<br />
• Low cost heatsinks and fans.<br />
• Large supplier base and range of options.<br />
• Air can cool other components such as bus bars,<br />
electronic circuits.<br />
• Low maintenance.<br />
• Very broad design knowledge base.<br />
Cons<br />
• Not very efficient for heat transfer.<br />
• Large volume of air requires ducting which can impose<br />
constraints on mechanical layout and design.<br />
• Space inefficient.<br />
• Air can contain water/contamination.<br />
• Acoustical noise.<br />
• Performance is affected by altitude.<br />
