Abstract
Abstract A cylindrical heat exchange or radiator, one end of the cylinder being provided with a pair of concentric manifolds. A water inlet is connected to one manifold and a water outlet is connected to the other manifold. The manifolds are connected to a plurality of longitudinally extending heat exchange members and each member is provided with a water flow path therein so that water flows from one manifold through the flow path to the next manifold. The other end of the cylinder is connected to a fan to cause air to flow over the members and out through an opening adjacent the two manifolds.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
174 words
A cylindrical heat exchanger, particularly for the cooling of an internal combustion engine, one end of the heat exchanger being provided with a pair of concentric manifolds, one of said manifolds being an inner manifold and radially spaced from the other manifold which is an outer manifold; a water inlet connected to one of the manifolds and a water outlet connected to the other manifold; a plurality of radially spaced heat exchange members extending longitudinally of the heat exchanger between said pair of manifolds and the other end of said heat exchanger, each said heat exchange member having a water flow path therein; said flow path having an inlet and an outlet; said inlet being connected to said one manifold and said outlet being connected to said other manifold; and an axial flow fan at said outer end of said heat exchanger and mounted axially thereof to cause a flow of air to pass longitudinally of said heat exchanger over said heat exchange members and out through an opening adjacent to said two manifolds.
Claim 2
Dependent Claim
174 words
A cylindrical heat exchanger, particularly for the cooling of an internal combustion engine, one end of the heat exchanger being provided with a pair of concentric manifolds, one of said manifolds being an inner manifold and radially spaced from the other manifold which is an outer manifold; a water inlet connected to one of the manifolds and a water outlet connected to the other manifold; a plurality of radially spaced heat exchange members extending longitudinally of the heat exchanger between said pair of manifolds and the other end of said heat exchanger, each said heat exchange member having a water flow path therein; said flow path having an inlet and an outlet; said inlet being connected to said one manifold and said outlet being connected to said other manifold; and an axial flow fan at said outer end of said heat exchanger and mounted axially thereof to cause a flow of air to pass longitudinally of said heat exchanger over said heat exchange members and out through an opening adjacent to said two manifolds.
Claim 3
Dependent Claim
