Market Introduction

A heat pipe is a passive heat transfer device that utilizes phase change (evaporation and condensation) of a working fluid to transfer heat efficiently between two surfaces. The process involves:

1. Heat absorption at the evaporator end
2. Vapor transport to the condenser
3. Heat release via condensation
4. Fluid return via capillary action or gravity

This closed-loop mechanism provides extremely high thermal conductivity with minimal energy consumption.

Heat pipes are widely used in:

• Smartphones, gaming consoles, laptops
• Electric and hybrid vehicles
• Telecom infrastructure
• Aerospace systems
