An adaptive filling structure with high strength and high stiffness to enhance heat transfer

Abstract

A high-strength, high-rigidity self-adaptive filling structure that enhances heat transfer, including an upper plate and a lower plate, including more than one middle plate between the upper plate and the lower plate, and between the lower plate and the middle plate, the adjacent There is a filling layer between the middle plates, between the middle plate and the upper plate, and the hot air flow of the high-temperature components and the cooling air flow of the equipment are mixed through the filling layer; the filling layer is arranged in a staggered arrangement of circular convex hulls and multi-point cross brackets Composition, the circular convex hull adopts a symmetrical arrangement, the hot air flow of the high-temperature components and the cooling air flow of the equipment pass through the circular convex hull of the filling layer and the multi-point cross bracket, so that the hot and cold air flow forms a vortex and enhances convective mixing; the invention realizes enhanced exchange The mechanical properties of heat, high strength and high stiffness can be widely used in hot end parts of industrial gas turbines, aero engines and other complex high-end equipment.
