Abstract
A convectively-cooled hydraulic fluid tank system comprises a hydraulic fluid tank and a fluid cooler incorporated into the hydraulic fluid tank. The fluid cooler includes a vortex chamber having a wall made of a heat conductive material. An inlet is provided to direct incoming pressurized hydraulic fluid tangentially onto the inner surface of the vortex chamber wall to create a swirled flow of hydraulic fluid against the inner surface of the wall. A cooling structure extends from an exterior surface of the vortex chamber wall to promote heat dissipation.
