A heat exchanger () comprises a heat exchanger core () comprising first fluid channels () and second fluid flow channels () for exchange of heat between the first and second fluids. First and second manifold portions () are provided to guide the first and second fluids between the first and second fluid flow channels (and first and second fluid interface portions () which comprise fewer channels than the heat exchanger core (). The first manifold portion () includes at least one tunnel portion () extending through the second manifold portion () at an angle to the direction of second fluid flow. Hence at least part of the first fluid is directed through the inside of the tunnel portion while the second fluid passes around the outside of the tunnel portion. This enables more compact heat exchanger design.

Heat exchanger

A heat exchanger component comprises a core portion with alternating first and second heat exchanging channels. A first ducting portion comprises first ducting channels for transfer a first fluid between a first fluid inlet/outlet and the first heat exchanging channels of the core portion, and second ducting channels for transfer of second fluid between a second fluid inlet/outlet and the second heat exchanging channels of the core portion. The first ducting channels direct the first fluid around the turn of at least 45 degrees and the second ducting channels direct the second fluid around a turn of at least 90 degrees. The first and second ducting channels are interleaved.
