摘要：
A heat exchanger component 2 comprises a core portion 20 with alternating first and second heat exchanging channels (60, Figure 6). A first ducting portion 26 comprises first ducting channels (48) for transfer a first fluid between a first fluid inlet/outlet 14 and the first heat exchanging channels of the core portion 20, and second ducting channels (49) for transfer of second fluid between a second fluid inlet/outlet 12 and the second heat exchanging channels of the core portion 20. The first ducting channels direct the first fluid around a turn of at least 45 degrees and the second ducting channels 49 direct the second fluid around a turn of at least 90 degrees. The first and second ducting channels are interleaved. The heat exchanger may be made by additive manufacturing.
