Especially the frequency converters in the MCC panels used in this sector cause excessive temperature increase. For this reason, there is a need for proper ventilation to prevent the heating of the panels.
The temperature increase directly affects the performance of the devices in the panel or rack cabinet. Temperature rise tests, which are as important as short circuits in panel type tests, are critical for the safe and efficient operation of devices. Since the temperature increase reduces the current carrying capacity, it is necessary to bring the temperature in the panel/rack cabinet to the ideal level with proper ventilation.
The temperature in the panel/rack cabinet, the ambient temperature and the heat-emitting devices located inside (cutter, busbar, server, etc.) thanks to which it rises. This temperature increase is calculated by taking into account the electrical power loss values found in the catalogs of each device used.
The IP protection degree also contributes to the temperature increase by preventing the heat from escaping to the outside. Therefore, it is important to choose the right IP level, not high, for the clipboard/rack cabinet. A high IP protection rating does not always mean better protection, and the wrong choice can lead to excessive temperature rise and, therefore, damage to devices.
After the temperature increase is determined, the panel or rack cabinet can be cooled by the following methods according to the obtained value:
• Natural Ventilation
• Cooling by Fan
• Cooling with Air Conditioning
