A heat exchanger ( B, C, D) usable as an oil cooler is provided for exchanging heat between first and second fluids. The heat exchanger has an outer periphery ( ) spaced from a central axis ( ). The heat exchange includes an inlet ( ) and an outlet ( ) for flow of the first fluid, a pair of juxtaposed tube segments ( ) coiled about the central axis ( ) to form a plurality of alternating concentric coils ( ), an inlet ( ) for flow of the second fluid into heat exchanger ( A, B, C, D), an outlet ( ) for flow of the second fluid from the heat exchanger ( A, B, C, D), and structure ( ) for encapsulating the pair of tube segments ( ) to retain the second fluid within the heat exchanger ( A, B, C, D) as it flows from the inlet ( ) to the outlet ( ). The tube segment ( ) has an end ( ) connected to the inlet ( ) to receive flow of the first fluid therefrom. The tube segment ( ) has an end ( ) connected to the outlet ( ) to deliver flow of the first fluid thereto. The pair of tube segments ( ) are connected adjacent the central axis ( ) to transfer flow of the fluid between the tube segments ( ). The inlet and outlet ( ) for the first fluid are located adjacent the outer periphery ( ).

Spiral fin/tube heat exchanger

A method of installing a baffle ( ) in a tubular header ( ), ( ) for a heat exchanger includes the steps of a) providing a concavo-convex baffle ( ) with a periphery smaller than the internal periphery of the header ( ), ( ); b) locating the baffle ( ) at a desired location within the header ( ), ( ); and c) applying a compressive force ( ), ( ) to the baffle ( ) to compress the baffle toward a planar shape.

Improper assembly and/or dissociation due to improper handling of a tank 10 to header plate 14 joint in a heat exchanger is avoided through the use of a retaining strip 50 having fingers 54 receivable in slots 36 in an upstanding flange 26 surrounding a sealing surface 28 on the header plate 14. The fingers 54 are provided with hook-like formations 60, 62, 64 which lodge behind a surface 44 of the flange 26.
