11. They featured tablet avalanche rectifiers ( 12th class ) with natural air cooling . 12. For generators up to 300 MW, air cooling can be used. 13. Air cooling is by far the simplest, cheapest, and safest answer for most processors.14. In industrial water chillers is the use of water cooling instead of air cooling . 15. Air cooling is the process of cooling an object by exposing it to air.16. A fixed tailwheel cylinder heads protruding to allow air cooling . 17. Compared to air cooling , liquid cooling is also influenced less by the ambient temperature. 18. Thus, a solution was achieved by utilising a heat stop ventilation for fresh air cooling . 19. Additionally, the engine air cooling vents were considered to be vulnerable to small arms fire. 20. Air cooling is sufficient for lower average power levels.
