Abstract: A sealable module, cooled electronic system and method are described relating to cooling a heat generating electronic device. The sealable module is adapted to be filled with a first cooling liquid and a heat transfer device having a conduction surface defines a channel for receiving a second cooling liquid. In one embodiment, at least a portion of the conduction surface or housing is shaped in conformity with the shape of the electronic component. Control of the second cooling liquid is also described. Transferring heat between the second cooling liquid and a third cooling liquid features in embodiments. A method of filling a container with a cooling liquid is further detailed.

Abstract: A cold plate, comprises: a housing having a surface providing a thermal interface for cooling an electronic device; a channel within the housing proximate to the surface for a liquid coolant to flow therethough such that heat received by the thermal interface is transferred to the liquid coolant; and a coolant port extending outside the housing, for transferring liquid coolant to and/or from the channel. A cross-sectional area of an outlet from the coolant port to the channel may be no larger than that of the channel at the outlet. Pins and/or fins may be arranged within the channel adjacent to the coolant port. The coolant port may cause liquid coolant to enter and/or exit the channel in a direction perpendicular to the surface. The coolant port may comprise an independent rotating fluid connector thereby allowing adjustment in the direction of a pipe coupled to the coolant port.

Abstract: Heat sink and heat sink arrangements are provided for an electronic device immersed in a liquid coolant. A heat sink may comprise: a base for mounting on top of a heat-transmitting surface of the electronic device and transferring heat from the heat-transmitting surface; and a retaining wall extending from the base and defining a volume. A heat sink may have a wall arrangement to define a volume, in which the electronic device is mounted. A heat sink may be for an electronic device to be mounted on a surface in a container, in an orientation that is substantially perpendicular to a floor of the container. Heat is transferred from the electronic device to liquid coolant held in the heat sink volume. A cooling module comprising a heat sink is also provided. A nozzle arrangement may direct liquid coolant to a base of the heat sink.
