Abstract: In the speech is presented a generalized method to determine the performance of different types of heat exchanger starting from the behaviour of different Elementary Heat Exchanger (EHE), as part of an assembly. Algorithms, with computer aided analyse and application in the specific case of heat pipe heat exchanger (HPHE) is presented, also. The EHE (the Heat Pipe in the case of HPHE) has a self performance depending on the different operating conditions. Inside the heat exchanger, usually, we have a combination of the EHE in a parallel, a series or a mixed arrangement. The performance (behaviour) of each EHE depend, essentially, on the position inside the exchanger, taking in account that the temperatures of both fluids are variable in the longer of the exchanger. Finally, the overall performance of the exchanger is a sum of the performance of the total number of EHE. The algorithm to predict the performance oh HPHE is based on the knowledge of the behaviour of EHE in very different conditions (behaviour obtained by laboratory tests) and on the use of a specific software, which is presented more detailed in the lecture.
