Heat Exchanger Diagram - How Thermal Energy Transfer Works #212254 (License: Personal Use)

This diagram depicts a shell-and-tube heat exchanger where a primary fluid circulates through coiled inner tubes while a secondary fluid flows around them in the outer shell, enabling efficient thermal energy transfer. The blue lines indicate the path of the cooling or heating medium, and the vertical tube bundle represents the heat-transfer surface area. Such designs are common in HVAC, refrigeration, and industrial process systems.

Used on engineering education pages, technical manuals, or product documentation for HVAC equipment; targets users seeking to understand heat exchanger fundamentals or troubleshoot thermal system performance.
