<p>A cooling system is configured to control the flow of a refrigerant by controlling the rate at which the refrigerant is heated, thereby providing an efficient and reliable approach to cooling a load (e.g., magnets, rotors). The cooling system (10) includes a conduit circuit (15) connected to the load (14) and within which a refrigerant circulates; a heat exchanger (12); a first and a second reservoir (18, 20), each holding at least a portion of the refrigerant; and heaters (38, 40) to independently heat the reservoirs. In a first mode, the heater (38) heats the first reservoir (18), thereby causing the refrigerant to flow from the first reservoir (18) through the load (14) and heat exchanger (12), via the conduit circuit (15) and into the second reservoir (20). In a second mode, the heater (40) heats the second reservoir (20) to cause the refrigerant to flow from the second reservoir (20) through the load (14) and heat exchanger (12) via the conduit circuit (15) and into the first reservoir (18).</p> |
