Abstract
A heat exchanger (12, 12B, 12C, 12D) usable as an oil cooler is provided for exchanging heat between first and second fluids. The heat exchanger has an outer periphery (112, 156, 58′, 366) spaced from a central axis (56). The heat exchange includes an inlet (42, 378) and an outlet (44, 380) for flow of the first fluid, a pair of juxtaposed tube segments (52, 54) coiled about the central axis (56) to form a plurality of alternating concentric coils (58), an inlet (46) for flow of the second fluid into heat exchanger (12A, 12B, 12C, 12D), an outlet (48) for flow of the second fluid from the heat exchanger (12A, 12B, 12C, 12D), and structure (50) for encapsulating the pair of tube segments (52, 54) to retain the second fluid within the heat exchanger (12A, 12B, 12C, 12D) as it flows from the inlet (46) to the outlet (48). The tube segment (52) has an end (64) connected to the inlet (42) to receive flow of the first fluid therefrom. The tube segment (54) has an end (66) connected to the outlet (44) to deliver flow of the first fluid thereto. The pair of tube segments (52, 54) are connected adjacent the central axis (56) to transfer flow of the fluid between the tube segments (52,…
