A COOLING UNIT FOR COOLING A HEAT-GENERATING COMPONENT AND A METHOD THEREFOR

A cooling unit (1) for cooling a heat-generating component, comprising- at least one inlet (5) for inflow of air (Φin) into the cooling unit and at least one outlet (7) for outflow of air (Φout) from the cooling unit, an air-moving device (30), and at least one heat sink comprising abase thermally connectable to a heat-generating component and comprising a plurality of cooling fins (54) that project from the base. The cooling unit comprises a first cooling section (51) comprising cooling fins (54) and a second cooling section (52) comprising cooling fins (54), and the first and second cooling sections form a layered configuration in relation to the first base. At least some of the cooling fins project from a first base (53) of a first heat sink (50), which base is thermally connectable to a heat-generating component. The at least one inlet (5) is arranged in one of the first and second cooling sections and the at least one outlet (7) is arranged in the other of the first and second cooling sections. The air-moving device (30) is arranged to move air between the first cooling section (51) and the second cooling section (52), whereby an inflow of air is obtained in one of the first and second cooling sections and an outflow of air is obtained in the other of the first and second cooling sections. A corresponding method for cooling is disclosed.
