<p>A drilling mud cooler (230) includes a first mud heat exchanger (232a) that is adapted to receive a flow of drilling mud (210y), a first closed-loop cooling system (250) that is adapted to cool a first cooling fluid (260) that is circulated through the first mud heat exchanger (232a) so as to reduce a temperature of the flow of drilling mud (210y) from a first temperature to a second temperature, a second mud heat exchanger (232b) that is adapted to receive the flow of reduced temperature drilling mud (210y) from the first mud heat exchanger (232a), and a second closed-loop cooling system (270) that is adapted to cool a second cooling fluid (280) that is circulated through the second mud heat exchanger (232b) so as to further reduce the temperature of the flow of drilling mud from the second temperature to a third temperature.</p> |
