Temperature rise within electric cabinets primarily comes from electrical components, such as: Warmth also comes from external environmental conditions, such as outdoor air or direct sunlight. Enclosures mounted directly on walls may endure a higher temperature rise because they have less surface area to disperse heat.
Calculating temperature rise in an enclosure might sound technical, but it’s actually pretty straightforward once you break it into steps. Here’s how you can do it: Start with figuring out how much heat is being generated inside the enclosure. This is typically done by summing up the total power consumption of all internal components.
Additionally, the acceptable temperature rise inside the enclosure is usually limited to 18°F (10°C) above the surrounding ambient temperature. Following these benchmarks helps protect sensitive components and maintain reliable performance. Heat can come from both inside and outside the enclosure.
Heat can build up quickly inside electrical enclosures, especially when they’re packed with working components. If the temperature gets too high, it can damage your equipment or cause it to stop working properly. In this article, we’ll show you how to calculate temperature rise in an enclosure.
