What You Are Selecting

A heat pipe exchanger is a bundle of sealed tubes with a working fluid. It transfers sensible heat passively - no motor, no airstream mixing. Effectiveness is lower (50-65 percent) but reliability is very high.

Key Selection Parameters

• Tube bundle size - more tubes and surface area raise capacity
• Working fluid - chosen for the operating temperature range
• Orientation - evaporator end must sit in the hot stream, condenser in the cold
• Fin spacing - tighter fins improve transfer but foul faster

Sizing Approach

Estimate the sensible load to recover, then size the bundle so the temperature lift stays within the fluid's effective range. Heat pipes are often used where a failed moving part would be costly.

Best-Fit Applications

• Remote or harsh environments
• Industrial extracts where reliability beats peak efficiency
• Any space where zero cross-contamination is mandatory

Verify

Confirm the rated effectiveness at your airflow and the fluid's temperature limits; heat pipes do not recover moisture.
