Abstract: Systems and methods are provided for controlling the temperature of an electronic component of a computer. In one embodiment, a system includes a compressor, a compact cooling block, a condenser, and a controller. The compressor compresses or cools a refrigerant. The condenser receives the refrigerant and condenses the refrigerant. The compact cooling block is thermally coupled to an electronic component of a computer, receives the refrigerant from the condenser, transfers thermal energy from the electronic component to the refrigerant, and sends the refrigerant to back to the compressor. The controller is in electronic communication with the compressor and controls the compressor based on a pulse-width modulation (PWM) signal in order to maintain a temperature range for the electronic component. In another embodiment, a system is provided that controls the temperature of a circulating liquid that, in turn, cools an electronic component of a computer.

Abstract: Methods and apparatus control the temperature of an electronic component of a computer. A temperature sensor is read that measures a temperature of an electronic component of a computer. The speed of a compressor is adjusted based on the read temperature to maintain a pre-defined temperature range for the electronic component. The compressor compresses a refrigerant. The refrigerant is sent to a condenser that condenses the refrigerant. The refrigerant is sent to a heat exchanger that is thermally coupled to the electronic component and that transfers thermal energy from the electronic component to the refrigerant. Finally, the refrigerant is sent back to the compressor. Solenoid valves can be used to control the flow of refrigerant to heat exchangers for one or more additional electronic components.

Abstract: Techniques for maintenance-free on-demand high-efficient hydrogen generation using a small amount of electricity are described. A piece of foam is provided in the fluid used to generate the hydrogen. The foam, similar to a sponge structure, includes a plurality of open cells to accommodate the fluid. In a sense, the foam has been made to have the maximum contact with the fluid. When applied on with an electrical power (current or voltage), the fluid causes electrolysis and pyrolysis to happen so as to generate hydrogen and oxygen (oxy-hydrogen). Depending on implementation, the electrical power is electronically pulsed electricity and helps drive the fluid in a container to vibrate at an electrical resonance of the container.
