Abstract: An oil cooler is disclosed that comprises a base plate including a recessed portion defined by an interior wall and an exterior wall and including an inlet port and an outlet port. The base plate further includes a divider wall positioned in the recessed portion and extending between the exterior wall and the interior wall to separate the inlet port and the outlet port, a plurality of protrusions arranged in the recessed portion to provide a plurality of tortuous flow paths through which oil flows from the inlet port to the outlet port, and a first set of cooling fins formed on a surface of the base plate opposite the recessed portion. A cover plate is attached to the base plate so as to cover the recessed portion and thereby define a cavity to circulate the oil therethrough, the cover plate including a second set of cooling fins formed thereon.

Abstract: An engine assembly is provided that includes an engine having a crankshaft that is caused to rotate response to a firing of the engine, a backplate affixed to the engine and comprising one or more air flow passages formed therethrough, and an engine cooling fan operatively coupled to the crankshaft so as to be rotated by the crankshaft, the engine cooling fan coupled to the crankshaft on a side of the backplate opposite the engine. The engine assembly also includes a fan cover mounted over the engine cooling fan and secured to the backplate, the fan cover including an opening through which an air flow is provided to the engine cooling. The backplate and the fan cover collectively form an air guide that directs a flow of cooling air generated by the engine cooling fan through the one or more air flow passages of the backplate and to the engine.
