Through hole aluminum foam has a large specific surface area, high porosity, wide heat diffusion space and high wall heat transfer, giving it a good heat exchange performance.Under the condition of natural convection, heat exchange can be conducted between the flow of gas or liquid in the pores of foamed metal such as through hole aluminum foam and the pore wall, so through hole aluminum foam is a good heat exchange material or heat dissipation material.Because of good fluid power transmission, the cooling performance of foam metal can even reach its heat conduction performance of density matrix, and uses the foam metal can enhance the heat exchanger of the aviation equipment, energy power with compact type heat sink and heat exchange of air cooling in cooling tower equipment capacity.For example, the de-icing device and anti-freezing device used in the airplane, the Through hole aluminum foam sheet is installed in front of the wings, and the heated gas or antifreeze is sprayed from the foamed aluminum plate to achieve the purpose of de-icing.
