Abstract
The present system utilizes a method for precision low pressure, low flow, single phase cooling at temperatures below liquid nitrogen (77 Kelvin) to 170 Kelvin at low cost. In a non-limiting embodiment, and as one aspect of the present invention, the system includes a liquid nitrogen source, a heat exchanger, a pump, a sensor, a controller, a thin wall heat exchanger and a coolant consisting of a eutectic alkene or alkane and insulated lines. In a non-limiting example, the system is attached to a sample that is sensitive to vibration and stress.
Claims10
A system of controlled cryogenic cooling at low pressure and low system vibration, said system comprising:
- a liquid nitrogen source;
- a heat exchanger for allowing two fluids at different temperatures to exchange heat;
- a pump;
- a sensor;
- a controller;
- a thin wall heat exchanger;
- insulated lines;
- and
- a coolant comprising a eutectic alkene or alkane.
A method of controlled cryogenic cooling at low pressure and low system vibration, said method comprising the step of:
- providing a system that comprises a liquid nitrogen source, a heat exchanger, a pump, a sensor, a controller, a thin wall heat exchanger, insulated lines, and a coolant comprising a eutectic alkene or alkane, wherein said heat exchanger allows two fluids at different temperatures to exchange heat.
