Abstract:
A heat transfer structure comprising:an impingement surface from which heat is to be removed by a coolant impinging thereon;outer wall means having an outer surface which acts as a boundary of a plenum chamber containing pressurized coolant and an inner surface confronting and spaced from the impingement surface to define a cavity between the impingement surface and the outer wall means;coolant inlet means;coolant outlet means;the coolant inlet means comprising an array of apertures in the outer wall means for generating a corresponding array objects of coolant fluid for impingement on the impingement surface, thereby establishing a flow of coolant fluid from the plenum chamber into the heat transfer structure and over the impingement surface to the coolant outlet means; andflow diversion means associated with each of the apertures in the outer wall means to divert the impingement jets and establish an oblique impingement of the coolant fluid upon the impingement surface, wherein each said flow diversion means has an exterior surface which protrudes into the cavity from a location on the inner surface of the outer wall means adjacent an associated aperture, each associated aperture being located outside of the respective flow diversion means to direct the coolant fluid over the exterior surface of the flow diversion means, each said flow diversion means being inclined away from each associated aperture.
