A heat exchanger (10) comprising a first heat transfer tube (100) having a first primary straight part (101) and a first secondary straight part (103), the straight parts (101, 103) extending parallelin a first plane (P) in a longitudinal direction (di). The heat exchanger (10) comprises a first primary bond part (510) having a first primary surface (511), an opposite first secondary surface (512) and a first tertiary surface (513), the first tertiary surface (513) extending from the first primary surface (511) to the first secondary surface (512). On the first tertiary surface (513), a firstprimary hole (514) and a first secondary hole (515), are provided, both extending through the first primary bond part (510) in the longitudinal direction (dl). The heat exchanger (10) comprises a first secondary bond part (520) having a second primary hole (524) and a second secondary hole (525), both extending through the first secondary bond part (520) in the longitudinal direction (dl) on a second tertiary surface (523
