Patent ID: 7983040

Claim:
An apparatus for facilitating cooling of an electronic subsystem, the apparatus comprising: a container sized to receive an electronic subsystem therein, the electronic subsystem comprising multiple different types of components disposed on a circuit board; a coolant inlet port and a coolant outlet port coupled to the container for facilitating ingress and egress of coolant through the container, wherein when the electronic subsystem is operatively inserted into the container and coolant flows therethrough, the multiple different types of components of the electronic subsystem are immersion-cooled by the coolant, with the coolant flowing over and covering the multiple different types of components of the electronic subsystem; a coolant pump assembly coupled in fluid communication with the coolant inlet port and the coolant outlet port of the container for facilitating active pumping of coolant through the container in a direction parallel to the circuit board over the multiple different types of components to provide pumped immersion-cooling of the electronic subsystem when operatively disposed therein; and a filler element disposed within the container over the multiple different types of components and sized and configured to reduce an amount of the coolant within the container, the filler element projecting from over the multiple different types of components to between multiple components of the multiple different types of components to partially displace coolant within the container between the multiple components, while still maintaining the multiple different types of components of the electronic subsystem immersion-cooled by the coolant.
