The role of aluminum in radiators

The role of aluminum in radiators

Highly efficient thermal conductivity

Aluminum has high thermal conductivity and can transfer heat quickly. Such as computer CPU heat sink with aluminum, can quickly absorb and conduct heat, accelerate the dissemination. Its coefficient of thermal conductivity is slightly lower than copper, but lightweight and cost advantage is obvious, into the first choice.

Aluminum thermal diffusivity is good, so that the heat is evenly distributed to avoid local overheating, enhance the thermal efficiency and stability of the equipment, the power of the electronic components commonly used in heat dissipation.

Light weight advantage.

Electronic equipment, automotive and other weight-sensitive areas, aluminum lightweight characteristics. Such as notebooks with aluminum heatsinks, to ensure heat dissipation while reducing the weight of the machine to enhance portability.

Lighter weight reduces energy loss in equipment operation, which is beneficial to mobile devices and high energy efficiency equipment, which can extend battery life or reduce consumption.

2. the radiator shell

Protection of internal structure

Aluminum shell physical protection is good, can resist external objects damage to the internal cooling structure and fan. Such as industrial equipment radiator, aluminum shell can prevent dust and debris into the internal impact of heat dissipation.

Surface oxide film anti-corrosion and anti-oxidation, the harsh environment can still protect the performance and extend the life of the radiator. Appearance and design

Aluminum by the surface treatment of color texture variety, anodic oxidation of black, silver, gold and other colors to meet the aesthetic.

Easy to process molding, can be customized. Such as automobile radiator shell according to the automobile shape and engine compartment layout design, to mention the adaptability.

3、Heat dissipation fins

Increase the heat dissipation area

Aluminum fins are the key components, and the reasonable design of aluminum fins can improve the heat dissipation efficiency. For example, high-end graphics card coolers have dense aluminum fins for effective heat dissipation.

By increasing the number of fins and adjusting the shape and spacing, the heat dissipation is accelerated.

Optimize Air Flow

The shape and arrangement of aluminum fins affects air flow and heat dissipation. Proper design can facilitate smooth air flow and improve convection heat transfer coefficient.

Wavy or serrated aluminum fins disturb the air boundary layer to increase turbulence and improve heat dissipation efficiency.
