Abstract
Abstract An improved radiator for use in the cooling system of a vehicle including a plurality of cooling conduits interconnecting an inlet manifold and an outlet manifold. The tubes are horizontally disposed creating efficient cooling of the fluid passing through the radiator by inducing uniform cross flow between the manifolds and the tubes. The manifolds may be constructed of a suitable durable and flexible material such as rubber and are advantageously molded in a one-piece construction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
A radiator comprising an molded inlet manifold for receiving fluid being circulated in a cooling system, said inlet manifold including a plurality of hollow projections forming outlet ports a plurality of cooling tubes removably coupled at one end to the hollow projections to receive fluid being circulated and reduce the temperature thereof, an outlet manifold for receiving fluid from the cooling tubes, said outlet manifold including a plurality of hollow projections forming inlet ports to the manifold and being coupled to the other end of the cooling tubes, said inlet manifold and outlet manifold are constructed from a one-piece resilient material, clamp means for retaining the ends of the cooling tubes partially within the respective hollow projections of the iNlet manifold and the outlet manifold, and said clamp means being positioned in surrounding relationship to each of the hollow projections to effect frictional contact between a respective tube and the interior of a respective projection.
Claim 2
Dependent Claim
155 words
