Jaro Thermal‘s new (maintenance free) Ultra-slim heatpipes use water as a “working fluid” that continually alternates between evaporation and condensation. This constant cycling of water to vapor is caused by a high-capillary mesh wick inside of the heatpipe. As the vapor travels away from the heat source, it cools and undergoes a phase change of condensation. Once the water is
