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. %@area FISMAT %@electronicmailaddress lucas.hein@inpe.br %@electronicmailaddress marcus.mortean@ufsc.br %@documentstage not transferred %@group CMS-ETES-DIPGR-INPE-MCTI-GOV-BR %@dissemination WEBSCI; PORTALCAPES; SCOPUS. %@usergroup simone %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Universidade Federal de Santa Catarina (UFSC) %@versiontype publisher %@holdercode {isadg {BR SPINPE} ibi 8JMKD3MGPCW/3DT298S} %@doi 10.1016/j.icheatmasstransfer.2021.105237 %2 sid.inpe.br/mtc-m21c/2021/04.02.15.17.05
