Abstract: The invention relates to a cooling arrangement comprising a heat spreader (2) comprising a first surface (5), a second surface (8), at least one heat absorption chamber (9) and at least one heat dissipation chamber (10), the at least one heat absorption chamber (9) being in thermal contact with the first surface (5) and the at least one heat dissipation chamber (10) being in thermal contact with the second surface (8) and hydraulically coupled to the at least one heat absorption chamber (9). A cooling fluid (13) can be driven from the heat absorption chamber (9) to the heat dissipation chamber (10) using a plurality of flow patterns for cooling the first surface (5).
