ANALYSIS OF EVACUATED TUBE HEAT PIPE COLLECTORS USING OIL AND FOAMED METALS: - A REVIEW

Mechanical Engineering

The Evacuated tube collector includes a number of rows of parallel transparent glass tubes connected to a header pipe and that are used in region of the blackened warmness absorbing plate we saw in the previous flat plate collector. Different types of glass materials of heat pipe have been used with different profile. Inside the fluid flow (octadecane) nano fluid on heat pipe. We found that they gives better temperature distribution and mass transformation in capillary tube of heat pipe. Heat pipe evacuated tube collectors, a sealed heat pipe, usually made of copper to increase the collectors efficiency in cold temperatures, is attached to a heat absorbing reflector plate within the vacuum sealed tube. The hollow copper heat pipe within the tube is evacuated of air but contains a small quantity of a low pressure alcohol/water liquid plus some additional additives to prevent corrosion or oxidation.
