Embodiment Construction

[0087] Referring to the drawings, wherein like reference numerals denote like elements throughout the various figures, figure 1 A gas turbine engine 10 is depicted incorporating a heat exchanger arrangement constructed in accordance with aspects of the present invention, and while the example shown is a high-bypass turbofan engine, the principles of the present invention are also applicable to other types of engines, such as low-bypass, turbojet etc. Engine 10 has a longitudinal centerline or axis 11 , and an outer stationary annular casing 12 concentric about and disposed coaxially along axis 11 . Engine 10 has fan 14 , supercharger 16 , compressor 18 , combustor 20 , high pressure turbine 22 , and low pressure turbine 24 arranged in series flow relationship. In operation, pressurized air from compressor 18 is mixed with fuel and ignited in combustor 20 to generate combustion gases. Some work is extracted from these gases by a high pressure turbine 22 which drives the compr...

Abstract

A heat exchanger apparatus (40, 140, 240) for a gas turbine engine includes: a plurality of heat exchanger pipes (48, 148, 248), each pipe having first and second ends; wherein the heat exchanger pipes (48, 148, 248) are disposed in a repeating pattern such that each heat exchanger pipe (48, 148, 248) is joined to at least one other heat exchanger pipe.

Description

technical field [0001] The present invention generally relates to gas turbine engines, and methods for oil cooling in such engines. Background technique [0002] Gas turbine engines are typically provided with a circulating oil system for lubricating and cooling various engine components such as bearings, gearboxes, generators, and the like. In operation, the oil absorbs a large amount of heat, which must be rejected to the external environment in order to keep the oil at an acceptable temperature. Engine design has evolved to dissipate an increasing amount of heat. [0003] Known oil cooling systems for gas turbine engines typically include one or more air-to-oil heat exchangers, referred to as "air-cooled oil coolers" or "ACOCs," and may also include air-to-air heat exchangers device. These heat exchangers can be heavy and have high resistance and may require special inlet and outlet conduits and large, heavy supports. [0004] The high weight is due in part to the nee...
