Heating or cooling radiator

Claim 1

A radiator assembly for the circulation therethrough of a heat transfer fluid such as the cooling oil of a transformer, for example, the assembly comprising: a generally horizontally oriented inlet manifold having a closed end on one side and an inlet opening on its opposite side connectable to a fluid circulating system; a generally similarly oriented outlet manifold spaced a distance below the inlet manifold and having likewise a closed end on one side and an outlet opening on the opposite side connectable to said fluid circulating system; a plurality of hollow radiator members extending generally vertically and at regular intervals between the two manifolds, each radiator member including upper and lower openings for communication with both manifolds; and wherein at least the inlet manifold has its length subdivided into first and second length portions, the latter encompassing corresponding first and second groups of upper radiator member openings, respectively; the first manifold length portion has its flow section longitudinally subdivided into an upper flow channel leading from the inlet opening of the manifold directly to its second length portion, and a lower flow channel leading from the second manifold length portion to said first group of radiator member openings, thereby forcing the entire incoming fluid flow to initially bypass the first group of radiator member openings, the latter being reachable only through reversal of a portion of said flow, via the lower flow channel; and at least said inlet manifold is constituted in its upper portion by a manifold pipe and in its lower portion by adjoining enlarged throat portions at the upper ends of the radiator members.
