heat pipe

A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces.At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to the cold interface and condenses back into a liquid, releasing the latent heat. The liquid then returns to the hot interface through either capillary action, centrifugal force, or gravity and the cycle repeats.
Due to the very high heat transfer coefficients for boiling and condensation, heat pipes are highly effective thermal conductors. The effective thermal conductivity varies with heat pipe length, and can approach 100 kW/(m⋅K) for long heat pipes, in comparison with approximately 0.4 kW/(m⋅K) for copper.

    Advice on DIY heatpipes

    Hi guys, looking for a bit of advice. I'm experimenting with heating solutions for my outdoor potting shed & workshop & I'm putting together an electric tube heater connected to copper heat pipes. Now I'm starting off small just as an experiment to see if I can do it & then upscale if needs be...
