Abstract
Tube circuits for heat exchangers which provide same-end inlet and outlet connections are disclosed, in which each circuit includes conduits of two types. In a preferred embodiment, the first type conduit has two tubes and is generally U-shaped, and the second type conduit has four tubes. The inlets for each conduit are disposed adjacent each other in the assembled heat exchanger, as are the outlets for the conduits. To equalize flow and pressure drop a turbulence promoting device can be disposed in the U-shaped conduit. The circuits can be used for providing same-end connections on coils previously available only in opposite end connection configurations, such as for example, three-row full-circuited and six-row double circuited coils.
