摘要： A power module (1) includes a group of at least three rectangular electrical power components (11, 12, 13, 14, 23, 24, 25, 26) arranged on a substrate (2), wherein in that at least one side (31) of at least one of the rectangular electrical power components (11, 14) is not orthogonal or parallel to a line (3) that passes through the geometric centres of the remaining rectangular electrical power components (12, 13) of the group.

摘要： A cooling system (26) comprising a cooling arrangement (24, 24′, 24″) having a serpentine passageway (20) for a circulating fluid coolant is disclosed. The serpentine passageway (20) is provided between a plurality of walls (6, 8) displaced from each other. A series of baffles (10) each having a proximal portion (12) and a distal portion (14) are disposed within the passageway (20). The baffles (10) extend from one of the walls into the passageway (20). The distal portion (14) has a width (W2) that is larger than the width (W1) of the proximal portion (12).
