Heat Dissipation

Magnesium alloys are materials with excellent thermal conductivity and are often used to manufacture heat dissipation equipment such as radiators, heat exchangers, and liquid coolers to improve heat dissipation efficiency and reduce temperature.

Heat exchangers: A heat exchanger is a device that transfers heat from one medium to another. Magnesium alloy heat exchangers can be used in car engine cooling systems, air conditioning systems, industrial heaters, evaporators used in chemical production, and more. Their advantages include good thermal conductivity, corrosion resistance, light weight, and low cost.

Liquid coolers: A liquid cooler is a radiator that absorbs heat through liquid flow and takes it away. Magnesium alloy liquid coolers are commonly used for heat dissipation in high-power electronic devices such as computer CPUs and graphics cards. Compared to traditional copper liquid coolers, magnesium alloy liquid coolers are lighter, more corrosion-resistant, and have higher heat dissipation efficiency.

Radiators: A radiator is a device that uses airflow to dissipate heat. Magnesium alloy radiators are widely used in fields such as automobiles, airplanes, and industrial cooling. Due to the excellent thermal conductivity of magnesium alloys, radiators can transfer heat to the surrounding environment faster, improving heat dissipation efficiency.

Magnesium alloy heat dissipation equipment is widely used in various fields, especially in the automotive, aviation, electronics, and chemical industries.

For example, new design schemes, material combinations, and manufacturing processes can further improve the performance and efficiency of magnesium alloy heat dissipation equipment.

There are many different grades of magnesium alloys for heat dissipation equipment, and selection should be based on specific application scenarios and requirements. The following are some common magnesium alloy grades:

AZ31B: AZ31B alloy is a widely used magnesium alloy, composed of 3% aluminum and 1% zinc. It has good mechanical properties and corrosion resistance and can be used to manufacture heat dissipation equipment such as liquid coolers and heat exchangers.

AZ91D: AZ91D alloy contains 9% aluminum and 1% zinc and is a high-strength, lightweight magnesium alloy commonly used to manufacture automotive parts, aerospace devices, and radiators for other mechanical equipment.

WE43: WE43 alloy is a rare earth element-doped magnesium alloy with excellent high-temperature and oxidation resistance. It can be used for heat dissipation equipment under high-temperature environments such as high-speed train engine radiators and aircraft engine turbines.

ZK60A: ZK60A alloy contains 5.5% zinc and 0.4% zirconium and has high strength and excellent corrosion resistance. It is suitable for manufacturing liquid coolers and heat exchangers used in high-temperature environments.

The specifications of magnesium alloy heat exchangers, liquid coolers, and radiators are diverse and should be determined based on actual needs and usage environments. The following are some common specifications:

Magnesium alloy heat exchanger: can be customized based on different application scenarios and requirements. Common specifications include shell-and-tube heat exchangers, plate heat exchangers, etc., and their dimensions and thermal conductivity area parameters can be designed according to user needs.

Magnesium alloy liquid cooler: The specifications of the liquid cooler are usually determined by parameters such as flow rate, pressure loss, and heat dissipation power. For different types of liquid coolers, such as CPU liquid coolers and graphics card liquid coolers, the specifications will also vary, and selection should be based on specific equipment parameters.

Magnesium alloy radiator: Radiator specifications are usually determined by parameters such as heat dissipation area, thickness, and heat dissipation capacity. For example, the specifications of a PC case radiator are usually 120mm, 240mm, 360mm, etc., while the specifications of a car radiator are determined by the size and power of the car.

Magnesium alloy heat dissipation equipment has diverse specifications, and selection should be based on specific application scenarios and requirements. When selecting, multiple factors such as heat conductivity performance, heat dissipation efficiency, weight, and cost should be considered to achieve the best cost performance.
