1. A method for computer processing comprising:
providing in a tank a cooling liquid formed of a dielectric material;
the tank containing a plurality of computer processing units, each comprising:
an exterior housing having a bottom opening at a bottom end and a top opening at a top end and defining a closed peripheral wall between the top and bottom ends;
at least one computer processing board carrying electrical components mounted within the exterior housing which operates to carry out computer processing operations while generating heat;
the tank having a dividing sheet in the tank dividing the tank into a bottom manifold below the dividing sheet and a main portion of the tank above the dividing sheet;
the exterior housing of each computer processing unit being mounted on the dividing sheet with the bottom opening located at the dividing sheet and the peripheral wall upstanding within the tank to the top end which spaced from the dividing sheet;
a plurality of liquid transfer opening arrangements in the dividing sheet where each of the liquid transfer opening arrangement is associated with a respective one of the exterior housings to allow liquid from the bottom manifold to enter the exterior housing and pass through the bottom opening;
introducing the cooling liquid into the bottom manifold;
arranging a top surface of the liquid within the tank at a location which is above the top end of the exterior housings;
causing the liquid to enter through the liquid transfer opening arrangements into the exterior housings and to rise within the exterior housings by convection caused by the heat within the exterior housings and to exit from the exterior housings through the top end into the tank;
the liquid exiting from the top ends of the exterior housings forming a heated layer in the tank between the top surface and the top ends;
extracting liquid from the heated layer;
and extracting heat from the extracted liquid to create a heat supply and to return cooled liquid to the bottom manifold.
