Integrated fluid reservoir and heat exchanger ducts
First Claim
1. A molded tank and cooling component housing for a powered loader comprising a tank structure having first and second spaced apart side tank portions and a front tank portion joining the side tank portions, said tank portions having interior chambers that are in fluid communication with each other, the side and front tank portions forming an opening partially surrounded by the side and front tank portions, the opening, having a first section having first and second ends forming a fan chamber, a fan mounted in the fan chamber between the first and second ends of the fan chamber and adjacent a second end, the opening defining a plenum chamber between the fan chamber and the first end, the plenum chamber including at least one component through which air passes for cooling the component, the fan moving air through the plenum chamber, and discharge ducts extending from the fan chamber through passageways formed by surfaces of the side tank portions and opening to the exterior of the molded tank, wherein the surfaces of the side tank portions forming the discharge ducts incline upwardly in a lateral direction from the fan chamber to an outlet on a side of the powered loader.

Abstract
A combined liquid tank and fan air flow housing is molded as a unit to combine needed functions in a compact preassembled unit. Separate spaced side tank portions are formed that are joined together with a front end tank to form a central opening with upper and lower ends. The opening is closed with a top plate that defines a plenum chamber and a lower fan support plate that forms a fan chamber in the central opening. A fan in the fan chamber creates an airflow from the exterior through the plenum chamber and out lateral ducts formed in the side tank portions. The inlet air flows through an oil cooler, water radiator and if desired, an air conditioner condenser in the plenum chamber. The tank formed is used for storage of hydraulic fluid.
