Abstract: A cooling device for cooling a heat generating component, wherein the cooling device comprises a heat sink and at least one heat pipe that is in thermal contact with the heat sink, wherein the at least one heat pipe comprises a thermal contact area that is configured for thermal contact with a heat generating component, and the at least one heat pipe is configured in a shape that provides mechanical spring properties. Such a heat generating component may comprise a pluggable module. Also disclosed is a receptacle assembly comprising a frame having an interior cavity configured for accommodating a heat generating component and having an opening for receiving the heat generating component, characterized in that it comprises a cooling device. Disclosed is also a system comprising a receptacle assembly, and a printed board assembly (PBA) comprising a receptacle assembly.

Abstract: A method for reducing energy consumption for a base station providing multiple-input multiple-output, MIMO, communication on a mixed-mode carrier supporting at least two RATs is provided by determining sleep mode independently for the at least two RATs and performing port merging for at least one of the two RATs based on the determined sleep modes. An apparatus implementing the method is also disclosed.

Abstract: A cooling device for dissipating heat from an object. The cooling device comprises a base part arranged for contact with the object, and fins attached to and protruding from the base part in a direction substantially away from the object when in use. The fins are arranged in a first configuration adapted for heat dissipation by natural convection of air and in a second configuration adapted for heat dissipation by forced convection of ambient air movement such as wind. Thereby, the cooling device can provide ample or at least adequate cooling effect on the object both when there is more or less ambient air movement chiefly using the second configuration, and when the ambient air is not moving chiefly using the first configuration.

Abstract: A cooling unit (1) for cooling a heat-generating component, comprising- at least one inlet (5) for inflow of air (?in) into the cooling unit and at least one outlet (7) for outflow of air (?out) 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.
