U-tubes are usually used to exchange heat in process fluids with large radiators. The fluid is pumped out through a pipe, through a U-Junction, and then flows back along a pipe parallel to the inflow line.
U-Heat is transferred to the wrapping material through the wall of the tube, This design is used in industrial applications where many U-tubes can be poured into oil containers with high heat capacity.
