Abstarct: In order to optimize the efficiency and heat recovery for applications HPHE operating temperature heat pipe heat exchangers energy reserve of the system are considerable and more research is needed. Many parameters to optimize heat exchangers, heat pipes and heat from the perspective of economic efficiency and temperature optimum performance can be achieved by controlling these parameters. The important point in increase of energy recovery is the interval that they really work. Indirect methods are usually used for this purpose while the heat exchangers can also be used for this purpose. It is clear that the efficiency directly depends on the size and cost of the tube. It is noteworthy that prior to the installation of heating systems, heat recovery and economic feasibility study is necessary. Effective control of a flexible heat pipe is also important. They can easily play any type of heat transfer to the heat exchanger. The thermal resistance of heat pipe heat exchanger should be about the cause of the smaller and less payment. Heat pipe heat exchangers developed using the swing is started, including the Air preheater heat exchanger in thermal power plants, heat recovery from exhaust smoke and cooling the electronic components can be mentioned. It is clear that despite the simplicity of the construction of this type of recovery, the efficiency is significant. In this project, the efficiency of the heat exchanger tubes, thermal fluctuations in a sample tube heat recovery by thermal fluctuations that are designed and built. The results of simulation are also compared to implementation.
