A HEAT EXCHANGER AND AN ADDITIVE MANUFACTURING METHOD FOR MANUFACTURING A HEAT EXCHANGER

摘要

The invention relates to a heat exchanger (1) comprising a heat exchanger body (3) comprising at least a first channel wall portion (10), a second channel wall portion (20), and a third channel wall portion (30). The heat exchanger further comprises a first channel (5) for a first fluid, and a second channel (7) for a second fluid, such that heat is allowed to be transferred between the first channel and the second channel via the second channel wall portion. The heat exchanger comprises a plurality of first support structures (50) arranged in the first channel and extending from the first channel wall portion to the second channel wall portion, and a plurality of second support structures (70) arranged in said second channel and extending from the second channel wall portion to the third channel wall portion. The support structures are configured to support the second and third channel wall portions during manufacturing of the heat exchanger.
