<p>In the development of a compact heat exchanger with additive manufacturing, the thermal-hydraulic characteristics of a block type heat exchanger were experimentally evaluated. Three types of block type heat exchangers with different internal microchannel structures were manufactured by using powder bed fusion type metal 3D printer. As a result, it was confirmed that the heat exchange rate could be improved by staggered arrangement of the micro channels and by reducing the diameter of the channels. The performance prediction of the block type heat exchanger with microchannels is expected to be possible by modifying the heat exchange correlation based on the existing heat transfer correlation equation.</p>
