Additively manaufactured heat exchanger

An additively manufactured heat exchanger for media-separated heat transfer between a first fluid and a second fluid, comprising:

• an additively manufactured heat exchanger block that has a block longitudinal direction, a block transverse direction, and a block height direction that are perpendicular to each other,
• a plurality of first flow channels for conducting the first fluid disposed in the heat transfer block and penetrate the heat exchanger block,
• a first chamber disposed on the heat exchanger block at a first transverse end, the first transverse end extends in the block height direction,
• a second chamber disposed on the heat exchanger block at a second transverse end that is turned away from the first transverse end in the block transverse direction and extends in the block height direction,
• a plurality of second flow channels for conducting the second fluid disposed in the heat exchanger block, the plurality of second flow channels fluidically separated from the plurality of first flow channels that penetrate the heat exchanger block in the block transverse direction and fluidically connect the first chamber to the second chamber,
• a first connection for supplying or discharging the second fluid and a second connection for discharging or supplying the second fluid,
• wherein the plurality of second flow channels are arranged next to one another in the block longitudinal direction and form a longitudinal row of channels, and
• wherein a plurality of longitudinal rows of channels are arranged next to one another in the block height direction within the heat exchanger block.
