Heat Pipe/ Heat Pipe Assembly

      Heat Pipe/ Heat Pipe Assembly

      Heat pipe is a heat transfer device which uses the latent heat of evaporation and condensation to achieve high thermal conductance with a small temperature difference. Fujikura can provide cooling modules consisted of heat spreaders, heat sinks and fans.
