Abstract
A system and method for cooling electronics with compressed gas cylinders. A small, lightweight, scalable cooling system provides portability and cooling for electronic components in remote areas. In some cases one or more compressed gas cylinders are used with a metering valve and a temperature sensor to release gas into an expansion chamber or channels in thermal contact with a heat sink that is in thermal contact with an electric component.
Claims20
A compressed gas cooling system, comprising:
- at least one compressed gas cartridge having a connector end;
- a metering valve connected to the at least one compressed gas cartridge via a connector interface;
- a controller for actuating the metering valve in response to temperature threshold information from at least one temperature sensor;
- an expansion chamber in fluid connection with the metering valve;
- and
- a heat sink in thermal contact with an electronic component.
A method of cooling electronics, comprising:
- providing at least one compressed gas cartridge in communication with a metering valve;
- sensing, with a temperature sensor, the temperature of at least one electronic component;
- providing an expansion chamber coupled to the metering valve and in thermal contact with a heat sink which is in thermal contact with the electronic component;
- determining that a threshold temperature of the heat sink has been met;
- actuating the metering valve in response to the temperature threshold;
- releasing compressed gas from the compressed gas cartridge into the expansion chamber and producing a lower temperature expansion chamber;
- conducting a temperature transfer from the lower temperature expansion chamber to the heat sink producing a lower temperature heat sink;
- conducting a temperature transfer from the lower temperature heat sink to at least one electronic component.
A compressed gas cooling system, comprising:
- at least one compressed gas cartridge having a connector end;
- a metering valve connected to the at least one compressed gas cartridge via a connector interface;
- a controller for actuating the metering valve in response to temperature threshold information from at least one temperature sensor;
- and
- an aluminum heat sink having internal coolant passages that routes exhausted compressed gas from the gas cartridge, wherein the heat sink is in thermal contact with at least one electronic component.
