In this paper thermal modeling and optimal design of a heat exchanger for the fast axial flow (FAF) CO, laser cooling system are presented. The log mean temperature difference (LMTD) method is applied to estimate the heat exchange performance. The tube diameter, tube pitch, tube length, number of tubes in face and depth, tube passes and fin numbers...

Context 1
... design of such a particular heat exchanger differs from conven- tional ones due to special working condition of the FAF CO 2 laser (special medium and low pressure of gas mixture) and high temperature difference between input and output nozzles of the heat exchanger. Plate finned tube heat exchanger (see Figure 1) is highly recommended for FAF CO 2 lasers due to its high efficiency, low fouling resistance than other heat exchangers, com- pact structure and sufficient heat exchange performance [12][13][14]. There are effective parameters in plate finned tube heat exchanger design such as the tube diameter, tube pitch, tube length, number of tubes in face and depth, tube passes and the fin number. ...

Heat exchangers are widely used in the industry to allow the heat transfer between two fluids. For that reason, correctly sizing said devices poses a design problem in order to guarantee the efficiency and appropriate conditions of the equipment and the processes. In this paper, the geometry of a spiral-plate heat exchanger is optimized by means of...
