Turbulator radiator tube and radiator construction derived therefrom

An elongated turbulator radiator tube having an interior defining a fluid conduit, which turbulator radiator tube comprises:

• a first principal heat transfer surface having a first edge and a second edge;
• a second principal heat transfer surface having a first edge and a second edge;
• interconnecting surface means for independently interconnecting both said first edges and said second edges of said first principal heat transfer surface and said second principal heat transfer surface characterized by:
• each of said principal heat transfer surfaces having a plurality of turbulator barriers placed along the length thereof, each of the said turbulator barriers being deformed from said principal surfaces toward said interior of said tube and extending from about said first edge of said principal heat transfer surfaces to about said second edge of said principal heat transfer surfaces, each of said turbulator barriers being formed from two or more indentations;
• said principal heat transfer surfaces and interconnecting surface means being so constructed and arranged that said first principal heat transfer surface and said second principal heat transfer surface are bowed outwardly from said interior of said tube.

A radiator construction in which a pair of coolant tanks are interconnected by a plurality of hollow turbulator radiator tubes through which coolant may flow from one conduit tank to the other coolant tank and wherein corrugated heat transfer fins are mounted between juxtaposed ones of said turbulator radiator tubes extending between said coolant tanks, an improved construction for said turbulator radiator tubes which comprises:

• a first principal heat transfer surface having a first edge and a second edge;
• a second principal heat transfer surface having a first edge and a second edge;
• interconnecting surface means for independently interconnecting both said first edges and said second edges of said first principal heat transfer surface and said second principal heat transfer surface characterized by:
• each of said principal heat transfer surfaces having a plurality of flow diverting members placed along the length thereof, each of the flow diverting members being deformed from said principal surfaces toward said interior of said tube, said flow diverting members as a group extending from about said first edge of said principal heat transfer surfaces to about said second edge of said principal heat transfer surfaces, said flow diverting members being so arranged that said first principal heat transfer surface and said second principal heat transfer surface are bowed outwardly from said interior of said tube when interconnected by said interconnecting surface means.
