Patent ID: 6971441

Claim:
A device for removing heat from an object to be cooled down with a cooling agent comprising: a longitudinally extended cooling casing having a wall thereof mounted on the object for receiving heat transferred from the object, the cooling casing having a longitudinally directed passageway extending therethrough and a plurality of longitudinally extended fins formed in the passageway; a fan disposed adjacent one end of said passageway for generating an airflow therethrough to a discharge opening disposed at an opposing end of said passageway; a spray nozzle arranged to spray an amount of the cooling agent onto the fins of the cooling casing; a reservoir containing the cooling agent and supplying the cooling agent to the spray nozzle; a cooling agent detector disposed in the reservoir for sensing an amount of the cooling agent therein; and, a controller having a display unit and being operatively coupled to the spray nozzle and adapted to detect a temperature signal indicating a temperature of the object for selectively actuating the spray nozzle to spray the cooling agent onto the fins of the cooling casing to remove heat therefrom responsive to the temperature of the object exceeding an upper temperature limit, the controller being coupled to the cooling agent detector for receiving signals therefrom and the display unit displaying an amount of the cooling agent within the reservoir responsive to the signals received from the cooling agent detector.
