Abstract
A unitary jet impingement plate is formed including a body portion thereof and at least one manifold integrally connected with the body portion, each having internal passages in fluidic communication with one another. At least one jet impingement orifice is provided through a plate of the body portion of the jet impingement plate through which heat transfer fluid can be directed into a fluid jet of such heat transfer fluid from the jet impingement plate and for impinging on a component or object to the thermally effected thereby. The heat transfer fluid may be heated or cooled as required depending on the specific application. Preferably, the jet impingement plate is structurally enhanced by the provision of integral posts provided in a pattern within the body portion of the jet impingement plate. More preferably, a plurality of jet impingement orifices are provided in accordance with a predetermined pattern designed for a particular application. Such a unitary jet impingement plate including integral posts is advantageously made by using a sacrificial core designed to provide the body portion and manifold of the jet impingement plate, and depositing forming material about the sacrificial core. After deposition, at least one access opening is needed through which the sacrificial core can be removed by melting, dissolving or decomposing. The at least one jet impingement orifice or plurality thereof can be provided while the sacrificial core is within the jet impingement plate, after the sacrificial core is removed, or during the deposition step.
