The heat exchanger comprises a housing (100) with two heat exchange units (160, 180) comprising air channels (161, 162, 181, 182) extending between side walls of the housing (100). The housing (100) comprises a middle section (170) situated between the heat exchange units (160, 180) and two end sections (150, 190) situated at opposite ends of the housing (100). A side duct (130, 140) with an upper compartment (131, 141) and a lower compartment (132, 142) is situated at each side of the housing (100). Each side duct (130, 140) comprises an inlet opening (135, 145) at a first end of the side duct (130, 140) in one of the compartments (131, 132, 141, 142) and an outlet opening (136, 146) at a second opposite end of the corresponding compartment (131, 132, 141, 142) in the opposite side duct (130, 140). |
