US12284785 - Assembly and method for cooling an apparatus

The present disclosure comprises an evaporative cooling assembly ( 200 ) for cooling an apparatus ( 220 ), and a method for cooling an apparatus ( 220 ). The evaporative cooling assembly comprises a refrigerant tank ( 202 ), the refrigerant tank ( 202 ) containing refrigerant ( 204 ). The apparatus also comprises a first evaporator ( 210 ) configured to be positioned proximal to the apparatus ( 220 ), and a second evaporator ( 216 ) positioned to cool the refrigerant tank ( 202 ). Each of the first evaporator ( 210 ) and the second evaporator ( 216 ) are in fluid communication with the refrigerant tank ( 202 ), and the second evaporator ( 216 ) is positioned downstream of the first evaporator ( 210 ). The method for cooling a heated apparatus ( 220 ) comprises passing a refrigerant ( 204 ) from a refrigerant tank ( 202 ) to a first evaporator ( 210 ), which is located proximal to the apparatus ( 220 ). At least part of the refrigerant is evaporated, and then passed to a second evaporator ( 216 ), which is positioned to cool the refrigerant tank ( 202 ).
