Heat pipe

Product Overview

Excellent thermal conductivity solves heat generation problems
Fully customizable specifications are available, including bending and crushing processing and modularization.

A heat pipe is a heat transfer device that uses the latent heat of evaporation and condensation, and is capable of transferring large amounts of heat with a small temperature difference.
It is also possible to supply it as a cooling module equipped with a heat pipe, heat receiving plate, fins, fan, etc.

Strong Point/Feature

Excellent thermal conductivity
Fast thermal response
High temperature uniformity
Great design freedom
Maintenance-free and zero running costs
Lightweight and compact
