SolarArk heat pipe is a device characterized by a high heat transfer performance via process of evaporation, condensation and convection with excellent anti-freezing performance.

Heat pipes are suitable for a wide range of application including solar collectors, the SolarArk heat pipe has a lower thermal mass allowing the collector to have an accelerated start-up time.

The SolarArk heat pipe is manufactured from pure oxygen free red copper, vacuumed then charged with specially formulated water-based working fluid with nano-sized particles dispersed in the liquid to increase thermal conductivity and controlled freezing to avoid damage to heat pipe caused by copper swelling.

SolarArk heat pipes are one of the most important parts in the operating system. The two sections in a heat pipe are, the evaporator and condenser section is used to transfer heat from the absorber to the manifold. The process of heating is carried out through evaporation of the working fluid which is then transferred to the condenser section of the heat pipe located within the manifold, where condensation takes place. Driven by gravity the condensate flows back into the evaporator section where it evaporates again. This method of heating is very effective due to the vacuum within the heat pipe so the boiling point is reached at a much lower temperature 25°C.
