- W3138457056 abstract "Compact heat exchangers are characterized by high heat transfer surface area per unit of volume, mainly used in applications where space and weight are restricted, present in the aerospace, automotive and naval sectors. The study of new technologies to produce compact heat exchangers has grown considerably in recent years. One of the technologies that presents a great potential for this application, and which has been little explored, is additive manufacturing. This work presents a feasibility analysis of additive manufacturing to produce polymer compact heat exchangers. Experimental tests in prototypes, using the Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) technologies, were taken, aiming to evaluate the thermal and hydrodynamic behavior of the heat exchangers. They were tested with air at room temperature and water at high temperatures, over a wide Reynolds number range, from laminar to turbulent flow, comprising 150 experimental tests. Additionally, a mathematical model to predict the thermal behavior of the prototype was developed and validated experimentally, the theoretical and experimental heat transfer rate showed good agreement, with an average error of approximately 3.5%. Even with low thermal conductivity of the polymer, an overall heat transfer coefficient of 194 W/m2K was achieved." @default.
