Computer Room Refrigeration

High thermal conductivity

The thermal conductivity of aluminium is 237 W/(m·K), second only to copper, but its density is only one third of that of copper. In the air conditioning system of a computer room, aluminum foil fins combined with copper tubes form a heat exchanger, which can quickly transfer the indoor heat to the cooling medium (such as refrigerant or cooling water), significantly enhancing the cooling efficiency. For instance, the actual measurement of a certain data center project shows that after adopting aluminum foil heat exchangers, the energy efficiency ratio (EER) of the air conditioning system has increased by 15%, and a single cabinet can save 800kWh of electricity annually.

Lightweight and corrosion resistance

Aluminum foil has a low density (2.7g /cm³), which can reduce the weight of heat exchangers by more than 30% and lower installation and transportation costs.

Through surface treatment (such as hydrophilic coating and anti-corrosion coating), the corrosion resistance of aluminum foil is enhanced by five times, making it suitable for the high-humidity environment in computer rooms and extending the service life of equipment to over 10 years.

Excellent processing performance

Aluminum foil can be stamped into complex fin structures (such as corrugated type, louver type) to increase the heat exchange area. For instance, in a certain computer room air conditioning project, three-dimensional heat pipe heat exchangers were adopted. After optimizing the spacing of the aluminum foil fins, the heat exchange efficiency increased by 20%, and the system's energy efficiency met the national first-class standard.
