HEAT EXCHANGER ASSEMBLIES

A natural draft cooling tower device comprising a vertical tower; support means extending peripherally between the lower end of the tower and the ground such that said lower end is spaced from the ground, and a heat exchanger assembly associated with the tower comprising a plurality of heat exchange elements, characterized by that said assembly is located within the support means and each element comprises a multiplicity of tubes of substantially horizontal fins arranged in a-frames, the a-frames of each element being parallel and being at the same level, each frame comprising two a's groups of tubes that are mutually inclined in the form of an inverted v and both inclined with respect to a vertical plane that bisects the angle between them, a considerable part of the area inside the support means covering said elements and being arranged in at least two levels, the central element or elements being closer to the center of said area ions from the ground at a relatively lower level and being surrounded by at least one ring of outer elements spaced from the ground at a relatively higher level; and sealing means between the tower and the upper or higher ring of elements and between the elements at different levels to substantially prevent air entering said area from entering the tower without passing through one of said elements.
