Abstract: A thin coating of a solution containing a low surface energy material is applied on the inner surface of tubing of a condenser or an evaporator of an air conditioning system. The solution is run through the tubing of the heat exchanger and drained.

A polymer with a lower surface energy and chemical and thermal resistance is employed, such as silane, fluorocarbons, polyetheretherketon (PEEK) and polysulfone. The thin coating of the lower surface energy material in solution prevents lubricating oil from the compressor which mixes with the refrigerant from wetting over the inner surface of the tubing, encouraging the formation of oil droplets. By preventing the build up of lubricating oil, heat transfer is improved.

The bearing device may be a hydrodynamic sleeve bearing having a bearing housing defining a sump for maintaining lubricant fluid therein. The bearing sump is in fluid communication with a reservoir which maintains a supply of lubricant.

The heat exchanger uses an existing source of air from an operative pump motor to increase the air circulation through the cooling fins of the heat exchanger. The cooled lubricant is thereafter delivered to the bearing inlet and provides a cooler operating environment for the bearing system.

Abstract: A transmission fluid cooling system includes a cooler-bypass unit having a banjo bolt relief valve. The banjo bolt relief valve includes a head portion and a body portion. A relief valve is incorporated into the body portion. A valve seat is formed between the head portion and body portion.
