DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This specification is directed to the construction of an elongated turbulator radiator tube which defines a fluid conduit through which a coolant may flow in order to have heat removed therefrom. The specification is also directed to a radiator construction made from such elongated turbulator radiator tubes.
BACKGROUND ART AND PRIOR ART STATEMENT
No search was conducted on the subject matter of this specification in the U.S. Patent and Trademark Office nor in any other search facility. The prior art which I consider to be most relevant is discussed in detail in the BEST MODE AND INDUSTRIAL APPLICABILITY section of this specification.
It is a principal object of this invention to provide a new construction for an elongated turbulator radiator tube which permits the tube to be assembled with other radiator forming components in a manner which provides better heat transfer characteristics from the radiator tube to other components of the radiator structure. This better heat transfer characteristic permits more rapid cooling of a coolant passing through the radiator tube and can reduce the size of radiator required in order to give a predetermined amount of cooling capacity.
DISCLOSURE OF THE INVENTION
This invention relates to an elongated turbulator radiator tube having an interior defining a fluid conduit and a radiator construction made using the elongated radiator tubes with other radiator forming components.
In its broadest form, the elongated turbulator radiator tube of this invention is one which has an interior defining a fluid conduit. The tube comprises a first principal heat transfer surface having a first edge and a second edge and a second principal heat transfer surface also having a first edge and a second edge. Surfaces independently interconnect both the first edges and the second edges of the first principal heat transfer surface and the second principal heat transfer surface.
The invention is characterized in the following manner. Each of the principal heat transfer surfaces have a plurality of flow diverting members placed along the length thereof. The flow diverting members are deformed from the principal surfaces toward the interior of the tube. The flow diverting members, as a group, extend from about the first edge of the principal heat transfer surfaces to about the second edge of said principal heat transfer surfaces. The flow diverting members are so arranged that the first principal heat transfer surface and the second principal heat transfer surface are bowed outwardly from the interior of the tube when interconnected by the interconnecting surfaces.
In a more preferred embodiment of the elongated turbulator radiator tube of this invention, each of the principal principal heat transfer surfaces are characterized in the following manner. Each of the principal heat transfer surfaces have a plurality of turbulator barriers placed along the length thereof. Each of the turbulator barriers are deformed from the principal surfaces toward the interior of the tube and extend from about the first edge of the principal heat transfer surfaces to about the second edge of the principal heat transfer surfaces. Each of the turbulator barriers are formed from two or more indentations. The principal heat transfer surfaces and the interconnecting surfaces are so constructed and arranged that the first principal heat transfer surface and the second principal heat transfer surface are bowed outwardly from the interior of the tube.
The shape of the deformations used to form the flow diverting members, which may take the form of a turbulator barrier as will be defined hereinafter, may come in a variety of configurations. However, the most preferred configuration is one in which each turbulator barrier is formed from a plurality of elongated, rectangular deformations which extend perpendicularly across each of the principal heat transfer surfaces from the first edge thereof to the second edge thereof. Also in accordance with the preferred embodiment, the turbulator barriers on the
