A heat pipe heat sink is an advanced thermal management solution designed to efficiently transfer and dissipate heat from high-power electronic components. By embedding copper heat pipes into a high-thermal-conductivity aluminum base plate, this Heat Sink with heat pipe structure dramatically reduces thermal resistance and improves overall cooling performance.
Compared with conventional solid aluminum or copper Heat Sinks, a copper heat pipe heatsink utilizes phase-change heat transfer to move heat rapidly from the heat source to the fin area, making it ideal for industrial heat sink applications and high-density electronics.
Our pipe heat sink solutions are engineered using precision CNC-machined aluminum base plates with embedded or grooved copper heat pipes, ensuring excellent thermal contact, mechanical reliability, and long-term performance stability.

A heat sink is a passive thermal device used to dissipate heat generated by electronic components. Understanding what is a heat sink and how heat sinks work is essential for selecting the right cooling solution.
Heat generated by electronic components is transferred to the aluminum base.
The embedded copper heat pipe absorbs heat at the evaporation section.
Internal working fluid vaporizes and transports heat along the pipe.
Heat is released at the condenser section into the fin structure.
Vapor condenses and returns via capillary action, completing the cycle.
This phase-change mechanism allows heat sinks for electronics to achieve much lower thermal resistance compared to traditional solid heat sinks.
