Body assembly for a fluid cooler

A body assembly, for a fluid cooler, comprising:

• a body;
• said body having a curvilinear configuration, at least and being formed of one pair of mating elements;
• each of said elements having a first surface which defines an outer surface of said body, and a second surface which defines an inner surface of said body;
• said second surfaces of said elements each having a first, peripheral land formed thereon, and a second land spaced-apart from, and concentric with, said peripheral land;
• said peripheral lands of said elements and said concentric lands of said elements being closed upon each other to define a sealed interface therebetween;
• and
• rib means formed on said second surfaces of said elements, intermediate said lands thereof, which cooperatively define a single, undulating, fluid-accommodating channel within said body;
• said undulating channel-defining rib means comprises a multiplicity of ribs extending from and normal to said second surfaces of said elements;
• and
• said ribs subsist in discrete, equally spaced apart planes;
• and
• said ribs of each of said elements are interleaved with said ribs of the other of said elements in a non-contacting, equally-spaced apart, aligned relationship;
• wherein
• each of said elements is substantially a mirror image of the other thereof;
• said channel defines a fluid-accommodating pathway which (a) is concentric with said lands, and (b) constrains fluid flow therethrough to describe a multiplicity of reversing paths which extend between said second surfaces;
• and
• said channel has a greater peripheral dimension adjacent to said first land than it has adjacent to said second land, which provides said channel with a greater fluid-accommodating volume and cooling surface, adjacent to said first land than the fluid-accommodating volume and cooling surface thereof adjacent to said second land.
