  • Patent number: 4590538
    Abstract: An immersion cooling system for high density electronic assemblies such as computers includes a container holding an inert cooling liquid, and stacks of circuit modules arranged in a generally radial pattern within the container. Coolant supply columns and coolant removal columns alternate between adjacent stacks around the pattern. The coolant supply columns include distribution manifolds which distribute incoming coolant at all levels to provide a flow of coolant to all circuit modules. The flow passes between adjacent boards of the modules and preferably along flow channels formed by the circuit chips aligned in rows. After passing across the circuit modules the heated coolant rises in coolant removal columns and flows over standpipes for removal from the container, and a pump and heat exchanger recools and recirculates the coolant. Pump up and pump down systems are also provided for withdrawing the coolant to a reservoir for servicing the circuitry.

  • Patent number: 4128880
    Abstract: Vector processing in a computer is achieved by means of a plurality of vector registers, a plurality of independent fully segmented functional units, and means for controlling the operation of the vector registers. Operations are performed on data from vector register to functional unit and back to vector register with minimal delay, rather than memory to functional unit and return to memory with its attendant much greater start-up delays. Data may be bulk transferred between memory and some vector registers while other vector registers are involved in vector processing with one or more functional units. In vector processing elements of one or more vector registers are successively transmitted as operands to a functional unit at a rate of one per clock period, and results are transmitted from a functional unit to a receiving vector register at the same rate.
