Abstract
An baffle plug comprising a base and a blade extending therefrom. The baffle plug is used in a bore to divide the bore into longitudinally extending passages and cause the liquid to flow serially back and forth through the bore. The blade may comprise various fluid directing structures providing for efficient fluid flow across the surfaces of the blade. The blade may also comprise one or more structures which create turbulent flow of the fluid flowing across the surface of the blade.
Claims7
A baffle plug comprising
- a base;
- and
- a planar blade extending outwardly from said base, said planar blade having a first side and a second side, at least one of said sides having at least one fluid directing channel longitudinally extending along at least a portion of the length of said planar blade;
- wherein said planar blade has a plurality of peripheral protrusions disposed along at least a portion of the periphery of at least one side of said planar blade;
- and
- wherein said plurality of peripheral protrusions are disposed in a wave-like arrangement along at least a portion of the periphery of said planar blade.
