Cooling device for fluid submersion of electronics

A cooling device installation method, comprising:

• obtaining a cooling device which includes a coolant container that encloses at least a portion of a coolant space and at least a portion of at least one electronics device, the cooling device also including a connection block that is mechanically attachable to the coolant container, the connection block having a coolant-space-facing surface and an environment-facing surface, the connection block having an internal electronics connector on the coolant-space-facing surface, the connection block having on the environment-facing surface an external electronics connector which is electrically connected to the at least one electronics device when the at least one electronics device is electrically connected to the internal electronics connector, the cooling device also including a coolant input located on the environment-facing surface, the coolant input equipped with a valved inlet to the coolant space, and a coolant output located on the environment-facing surface, the coolant output equipped with a valved outlet from the coolant space;
• mechanically attaching the connection block to the coolant container;
• providing at least one rail, the at least one rail comprising a coolant supply, a coolant return, and at least one of a power connector or a data signal connector;
• placing the connection block on at least one rail, thereby
• connecting at least one of the following to the external electronics connector:
• the power connector, or the data signal connector;
• putting coolant into the coolant space until the at least one electronics device is substantially submerged in the coolant;
• and
• closing the coolant container, thereby separating the coolant space from an environment around the cooling device.

A cooling device for fluid submersion of electronics, comprising:

• a coolant bag which encloses at least a portion of a coolant space;
• a connection block which is mechanically attachable to the coolant bag, the connection block having a coolant-space-facing surface and an environment-facing surface which has cooling device connectors configured for physical and electric engagement with connectors of a rail, the connection block having an internal electronics connector on the coolant-space-facing surface and having an external electronics connector on the environment-facing surface which is electrically connected to the internal electronics connector, the cooling device connectors comprise a coolant input, a coolant output and the external electronics connector;
• the coolant input located on the environment-facing surface, the coolant input providing a coolant input path through the connection block and having a valved inlet to the coolant space;
• the coolant output located on the environment-facing surface, the coolant output providing a coolant output path through the connection block and having a valved outlet from the coolant space;
• and
• a closure which is operable to seal a volume of a coolant and at least one electronics device in the coolant space inside the coolant bag when at least a portion of the at least one electronics device is submerged in the coolant and when the at least one electronics device is mechanically and electrically connected to the internal electronics connector.
