AbstractLaser sintering technology(LST), which has been widely used recently, is a very important method to produce precise and qualified parts which cannot be manufactured with conventional methods. In this paper, the thermal behaviors and heat transfer performances of brazed plate heat exchanger (BPHE) and monoblock heat exchanger (MBHE) produced by laser sintering method from the AISI 316 stainless steel powder are numerically analyzed and experimentally investigated in an experiment setup. In analyzes, the inlet temperatures and mass flow rates of the hot and cold water are , and , , respectively . According to analysis results; outlet temperatures of cold and hot fluids circulated in MBHE are , respectively, while that in BPHE are and . According to experimental results, outlet temperatures of cold and hot fluids in MBHE were measured as , , respectively. As results of numerical and experimental analysis, heat transfer performance of the MBHE is 47.7% higher than BPHE, while its volume is 44.39% less. By comparing the results obtained from numerical and experimental analysis, it is observed that the results are consistent with each other
