The pores of closed cell aluminum foam plate are filled with gases with low heat transfer capacity, which makes the heat transfer capacity much smaller than that of solid materials.Through - hole aluminum foam has large specific surface area, high porosity, wide heat diffusion space and high wall heat transfer, giving it good heat exchange performance.Under the condition of natural convection, heat exchange can be conducted between the flow of gas or liquid in the pore of foamed metal such as aluminum foam through the hole and the pore wall, so  closed cell aluminum foam plate through the hole is a good heat exchange material or heat dissipation material.Due to its good fluid transmission power, the heat dissipation performance of the through-hole foam metal can even reach the heat conduction performance of its dense substrate. The use of this foam metal can enhance the heat exchange capacity of aviation equipment such as heat exchangers, compact heat sinks for energy power and air cooling cooling towers.For example, the ice elimination device and antifreeze device used on airplanes can achieve the purpose of ice elimination by putting the through-hole foam aluminum plate in front of the wing and expelling the heated gas or antifreeze agent from the  closed cell aluminum foam plate.



In the process of compression, a large amount of work will be converted into energy loss in the form of cellular deformation, collapse, bursting and mutual friction of aluminum foam, so aluminum foam can absorb a large amount of external impact energy.The damping of pure aluminum foam is 5 ~ 10 times that of aluminum foam.Using the excellent energy absorption and damping properties of aluminum foam, it can be made into excellent energy absorption and shock absorption materials, such as car bumpers, spacecraft landing gear, elevators, transport safety pads and energy absorption lining of high-speed grinding machine cover.
1.  closed cell aluminum foam plate has a wide range of applications. It is widely used in rail transit industry with its properties of low density, high stiffness, sound insulation, heat insulation, fire protection, energy absorption and non-release of gas when heated.Such as in the compartment and compartment on the heat and sound insulation, energy absorption and fire, gas parts.
2. Utilize the sound insulation, sound absorption and energy absorption of  closed cell aluminum foam plate for environmental protection in urban construction, such as sound insulation screen;The automobile industry is used for energy - and sound-absorbing components such as bumpers and mufflers.
