21. A fan connected across the grid provides forced-air cooling . 22. Taglioni preferred air cooling for thermodinamic, weight and size reasons so they were widely finned. 23. This occasionally causes equipment failures in hot environments, or when air cooling vents are blocked. 24. Air cooling efficiency is improved as aluminum is a superior thermal conductor to cast iron.25. Demand is set to improve in the summer when air cooling systems are in full use. 26. We adjusted the air cooling ducts a bit before the start to suit the rainy weather. 27. How does air cooling fit into the equation? 28. This reduces the occurrence of hot spots, which are more difficult to avoid with air cooling . 29. Air cooling and water cooling are usually combined.30. As they conduct several thousand amperes, the resultant power dissipated by the IGBTs requires forced-air cooling .
