  • HiK Aluminum Plates are aluminum plates embedded with copper/water heat pipes. These plates typically have effectively thermal conductivities between 500 and 800W/m-K, depending on the plate dimensions and heat pipe layouts. HiK plates have been used in cooling of RF components in military and commercial electronic systems.
