An air-cooled (forced air) oil cooler uses a fan to push ambient air across a finned core, transferring heat away from hydraulic or engine oil circulating through the unit. This design eliminates the need for a separate liquid coolant loop, making it common on construction equipment, compressors, and generators where compact, self-contained cooling is required.
