Abstract
A reliable, leak tolerant liquid cooling system with a backup air-cooling system for computers is provided. The system may use a vacuum pump and a liquid pump in combination to provide negative fluid pressure so that liquid does not leak out of the system near electrical components. The system distributes flow and pressure with a series of pressure regulating valves so that an array of computers can be serviced by a single cooling system. The system provides both air and liquid cooling so that if the liquid cooling system does not provide adequate cooling, the air cooling system will be automatically activated. A connector system is provided to automatically evacuate the liquid from the heat exchangers before they are disconnected.
Claims15
A system for cooling an electrical device, comprising:
- a fluid-containing heat exchanger thermally coupled to the electrical device;
- a fluid-containing reservoir in fluid communication with the heat exchanger, the reservoir defining an opening, the reservoir partially full of coolant fluid such that the coolant fluid is at a level below the opening;
- a fluid pump in fluid communication with the reservoir and the heat exchanger;
- and
- a vacuum pump in vacuum communication with said opening in said reservoir;
- wherein the fluid pump in combination with the vacuum pump causes the coolant fluid to flow from the reservoir through the heat exchanger and back to the reservoir under less than atmospheric pressure.
