The demand of energy is a major task for the worldwide generation stations and it is increasing per day for the human living. The researchers are broadly working for reversing the heat energy which is finally added into environment. This energy is waste energy which is exhausted from the thermal power generators at the rate of 15 to 20 % of generated heat energy. So the device which carries more amount of heat by making contact with waste heat is the Heat Pipe. Heat pipe is device working on two phase change of working fluid inside. This phase change of working fluid lead to increasing heat transport efficiency of heat pipe. The basic heat pipe working position is vertical position, when the heat pipe can transport maximal heat flow from evaporator to condenser. This article is mainly focusing on testing and implementation of heat pipe with axially groove wick structure for heat pipe heat exchanger ( HPHE).. The CFD results are more similar with experimental outputs and the energy distribution .This HPHE can be used to heat the sugar juice or feed water for the production process. This concept may be applied to save almost 10 % of energy which is exhausted per day. This conservation may useful for the reduction in thermal pollution of world.
