ABSTRACT:
An end cap is provided for adjacent pipes in the cooling coils of an electric air furnace. Each end cap includes parallel opposite side walls and a curved end portion connecting the side walls. The side walls and end portion define a perimeter edge, the outer portion of which is beveled. The end cap includes a pair of tabs extending from each side wall. The tabs partially fill the crevice between adjacent end pipes so as to provide a stronger weld between the end cap and the pipes. Internal turning vanes in the end cap minimize turbulence of the liquid coolant flowing through the pipes. Similar turning vanes can be provided in the 90.degree. elbows of the cooling coils.
