At present, power is an important factor in the production process of the industrial and business sectors sector households, regardless of whether it is power. Mechanical energy, thermal energy, etc., that are caused by the release of energy from different types of fuel out of fuel energy sources, which is rare nowadays. Cause of high prices is likely to step up because it is already out of fuel to a new offense, but demand for fuel to produce energy back with higher requirements. To take advantage of the fuel energy sources need to pull the power lead out. Work results in the most cost-effective Heat exchanger (Heat Exchanger) is one of the most important devices in many types of machinery and equipment used in manufacturing, such as honeycomb radiator in automobiles. The cooling circuit in the air conditioning, the main concepts to enhance heat transfer in heat exchanger, there are improved in various ways, such as to increase the surface area exposed. The combination of the increase of the flow. Use material that has a value of resistance, low heat release, etc. Generally, heat transfer is related to the pressure loss due to friction resistance. To increase the heat transfer, thus often causing loss of pressure increases. Many researchers use the top fin (Fin) or charcoal (Rib) in order to increase the heat transfer in a heat exchanger, which can help to increase heat transfer as well, but as a consequence it is the pressure loss values increased. Therefore, this project aims to make the study of heat transfer in heat exchanger pipe grooved surface and compare the results from an experimental study.
