Foam metal thermal properties include melting point, specific heat, thermal expansion coefficient, thermal conductivity, thermal diffusivity, thermal radiation and thermal shock resistance
The thermal properties of foam metal include melting point, specific heat, thermal expansion coefficient, thermal conductivity, thermal diffusion coefficient, thermal radiation and thermal shock resistance, some of which are the same as the matrix material, while others are closely related to the porosity, pore type and pore size of the foam material.
Materials with good thermal conductivity tend to absorb heat quickly and dissipate heat quickly. If some systems require a large amount of heat absorption or heat dissipation during use, materials with good thermal conductivity are selected. Frequency conversion radiators are ranked according to the thermal conductivity of pure metals, silver, copper, frequency conversion radiators aluminum, tungsten, magnesium and other materials, while the thermal conductivity of alloys is generally worse. It can be seen that the thermal conductivity of copper radiators is in industrial metals.
The thermal conductivity of copper is very good, and the frequency conversion radiator is because the thermal conductivity of copper is much higher than that of aluminum, which is also a fact. However, the heat dissipation capacity of a radiator depends not only on the thermal conductivity of the material, but also on the heat dissipation area, the shape of the radiator, and the air flow conditions. Common heat dissipation materials
The specific heat capacity of copper is small, and it is certain that the specific heat capacity of copper is low, and its temperature rises faster and it is easier to dissipate heat. However, the density of copper is 3.3 times that of aluminum. The radiator is a product of size and cannot be infinitely large. For the same volume, the weight of copper is greater.
