Abstract: The heat exchanger assembly includes a heat exchanger body and a plurality of columns of fluid passages arranged in a first direction within the heat exchanger body. The plurality of columns of fluid passages includes at least one first fluid column of fluid passages and at least two second fluid columns of fluid passages. The first fluid column is interspersed between two second fluid columns. The first fluid column includes a plurality of first fluid passages configured to channel a first fluid through the heat exchanger body. The at least two second fluid columns includes a plurality of second fluid passages configured to channel a second fluid through the heat exchanger body. The plurality of first fluid passages is offset with respect to the plurality of second fluid passages.

Abstract: A cooling system for use with a turbine engine. The system includes a coolant reservoir configured to store cooling fluid therein, and a cooling device coupled in flow communication with the coolant reservoir, wherein the cooling device is configured to cool heated components of the turbine engine with the cooling fluid. The system further includes a first valve configured to control flow of the cooling fluid from the coolant reservoir towards the cooling device, and a controller coupled in communication with the first valve. The controller is configured to monitor an operational status of the turbine engine, and actuate the first valve into an open position after the turbine engine has been shut down such that the cooling fluid cools the heated components.
