Abstract
An open loop liquid spray phase-change cooling system for a laser comprised of an expendable supply of a compressed liquid refrigerant, a laser heat sink, an on/off valve, and a means for controlling the on/off valve in response to the measured heat sink temperature.
Claims1
An open loop liquid spray phase-change cooling system for a laser comprised of:
- a heat sink disposed in heat transfer relation relative to a laser to be cooled;
- an expendable supply of compressed liquid refrigerant;
- an on/off valve connected to said supply of compressed liquid refrigerant and positioned with respect to said heat sink to deliver a uniform spray of said liquid refrigerant onto said heat sink whereupon said refrigerant vaporizes and is vented to the atmosphere;
- means for measuring the temperature of said heat sink;
- and
- means for controlling said on/off valve in response to the measured heat sink temperature.
