Multi-function oil tank

An oil storage container comprising:

• a top wall;
• a bottom wall, and side walls;
• an oil reservoir disposed in the oil storage container;
• an oil entry port configured to receive hot aerated oil to the oil storage container;
• an air and oil separation unit configured to receive hot aerated oil from the oil entry port and deposit hot de-aerated oil into the oil reservoir, to separate oil from the air, and to feed hot de-aerated oil into the oil reservoir;
• a heat exchanger disposed in the oil storage container, the heat exchanger comprising:
• an oil conduit disposed in the oil storage container substantially along the top wall, the bottom wall, the side walls, and around the oil reservoir,
• a coolant inlet to receive coolant fluid into the oil storage container to surround the oil reservoir and the oil conduit, and
• a coolant outlet for warmed coolant fluid to exit the oil storage container;
• and
• a container oil output port to receive cooled de-aerated oil from the oil conduit for distribution to components for lubrication.

An oil storage container comprising:

• a top wall;
• a bottom wall, and side walls;
• an oil reservoir disposed inside the oil storage container;
• an oil entry port mounted on the oil storage container to receive hot aerated oil into the oil storage container;
• a plurality of air and oil separation chambers disposed above a top surface of the oil reservoir in the oil storage container to separate oil and air and deposit cool de-aerated oil into the oil reservoir;
• a heat exchanger disposed in the oil storage container, the heat exchanger comprising:
• an oil conduit disposed in the oil storage container substantially along the top wall, the bottom wall, the side walls, and around the oil reservoir and connected to the oil entry port to receive the hot aerated oil,
• a coolant inlet to receive coolant fluid into the oil storage container to surround the oil reservoir and the oil conduit, and
• a coolant outlet for warmed coolant fluid to exit the oil storage container;
• and
• a container oil output port to receive cooled de-aerated oil from the oil reservoir for distribution to components for lubrication;
• wherein the oil conduit surrounds the oil reservoir in a space between the oil reservoir and an inner surface of the oil storage container and connects to the plurality of air and oil separation chambers to deliver cooled aerated oil to the air and oil separation chambers.
