A cooling arrangement (1) is provided in which a matrix (3) is arranged to provide a cascade path incorporating chambers (5) such that spent coolant which has impinged a target surface for cooling does not create a detrimental cross flow inhibiting subsequent down stream coolant jet impingement for cooling effect. The cascade path incorporates a permeable surface to divide a gallery portion and a cellar portion of each chamber (5) such that coolant flow passes through typically aperture jets in the permeable surface to become incident upon a target surface of a chassis (2), and the spent coolant is then collected within the cellar portion such that it flows through an outlet chimney slot formed between walls (25, 26). The coolant flow achieves a stepped flow elevation between successive chambers (5) in the cascade path for repeated jet impingement towards a target surface of the chassis (2). |
