Patent ID: 10612855

Abstract:
A modular heat exchanger assembly for ultra-large radiator applications. At least two heat exchanger cores are arranged in parallel flow, each core including inlet and outlet tanks sealingly attached to opposing headers at each end of a plurality of tubes. Each header is formed by securing mating header plates having mating openings. A plurality of O-rings are trapped within O-ring grooves formed by continuous depressions around each of the mating openings, and a portion of each tube is disposed within one of the O-rings and expanded outwardly to form a seal at each tube-to-header joint. A common tank is connected between tanks at adjacent ends of each heat exchanger core, and separate tanks are connected to the tank at the opposing ends of each core. The separate tanks may be inlet tanks and the common tank may be an outlet tank for fluid, or the flow path may be reversed.
