Abstract
A serpentine or parallely formed conduit is fixed within a support and is further joined on its exterior surfaces by a plurality of fins. The fins have a plurality of louvered cups which define openings in the fins so that air or other heat transfer medium will pass through the fins and be turbulated around the conduits for improved heat transfer. Within the conduits are strips having similar louvered cups and openings therein and these also enhance turbulance of the fluid passing through the conduits to augment heat transfer.
Claims8
A fluid turbulator for enhancing heat transfer from oil in an oil cooler of an internal combustion engine having at least one conduit which establishes a unidirectional fluid flow path for the oil from an inlet to an outlet comprising:
- a generally planar strip positioned in the conduit;
- means defining openings in said strip for permitting the flow of the fluid therethrough;
- and
- a plurality of louvered cups equal in number to said opening means and positioned at said opening means, and each having a leading edge extending out of the plane of said strip and a closed portion merging from said leading edge into the plane of said strip, said leading edges of all of said cups extending towards the inlet and into the path of the fluid flow and said closed portions of all of said cups extending towards the outlet and away from the path of the fluid flow, the combination of said cups and said opening means causing turbulence in the flow of the fluid and increasing contact of the fluid with the conduit for enhancing transfer of any heat in the fluid to the conduit, while minimizing impediment to the flow of the fluid.
