Insufficient cooling is a common issue in industrial equipment and systems that can have serious consequences if not addressed promptly. It refers to the inability of a cooling system to maintain proper temperatures in critical components. This can lead to overheating, reduced equipment lifespan, and potential failures.

Infrared thermography is an effective tool to identify insufficient cooling problems. This technique detects temperature differences on surfaces and components, highlighting areas experiencing higher-than-normal temperatures due to inadequate cooling.

A practical example of how infrared thermography can identify insufficient cooling is in engine cooling systems. If there's an issue with the cooling system, thermography can reveal areas where temperatures are abnormally high, indicating that cooling isn't functioning properly.
