Abstract

The invention relates to a bearing and heat dissipation integrated X-core corrugated wall square hole honeycomb and a preparation method thereof, and solves the problems of non-uniform flow distribution in the actual use process of an existing X-type lattice core sandwich plate and weak mechanical bearing and convection heat dissipation performance of the X-type lattice core sandwich plate. Partition plates are added to partition channels, so that the problem of uneven flow distribution in the actual use process of the X-type lattice core sandwich plate can be solved; and the mechanical bearing performance and the convection heat dissipation performance of the X-type lattice core sandwich plate are further improved by changing flat fins into corrugated fins.

Description

technical field [0001] The invention belongs to the technical field of thermal protection structures, and in particular relates to an integrated X-core corrugated-wall square-hole honeycomb for carrying and heat dissipation and a preparation method thereof. Background technique [0002] Open-cell metal lattice is a new multifunctional material with high porosity, efficient convection and heat dissipation, high specific strength and specific stiffness, high specific surface area and strong fracture toughness, and it has potential in many aspects such as energy absorption and shock absorption. Advantage. The lightweight sandwich panel with it as the core has the dual functions of mechanical load bearing and convection heat dissipation, and is especially suitable for thermal management of military equipment such as aircraft carrier gas deflectors and rocket engine combustion chambers, and military high-strength lightweight compact cross-flow heat exchange devices and other app...
