Processing and Forming Technology of Radiators
From some perspectives, the processing and forming technology of the radiator determines its final performance and is also the most important manifestation of the manufacturer's technical strength. At present, the mainstream forming technologies for radiators mainly include the following categories:
Aluminum Extruded Technology
Aluminum extrusion technology simply means heating the aluminum ingot at a high temperature of about 520-540 ℃, allowing the aluminum liquid to flow through the extrusion mold with grooves under high pressure to create the initial heat sink, and then cutting and grooving the initial heat sink to create the commonly used heat sink. Aluminum extrusion technology is relatively easy to implement and has relatively low equipment costs, which has also made it widely used in the low-end market in previous years. The commonly used aluminum extrusion material is AA6063, which has good thermal conductivity (about 160-180 W/m.K) and processability. However, due to the limitations of its own material, the ratio of thickness to length of the heat dissipation fins cannot exceed 1:18, making it difficult to increase the heat dissipation area in limited space. Therefore, the heat dissipation effect of aluminum extruded heat dissipation fins is relatively poor, making it difficult to cope with the increasing frequency of CPUs today.
Aluminum die-casting technology
In addition to aluminum extrusion technology, another commonly used process method for manufacturing heat dissipation fins is aluminum die-casting. By melting aluminum ingots into a liquid state, filling them into a metal model, and using a die-casting machine to directly mold them, heat dissipation fins can be made into various three-dimensional shapes using the die-casting method. The heat dissipation fins can be made into complex shapes according to needs, and can also be combined with fans and airflow directions to create heat dissipation fins with guiding effects, And it can make thin and dense fins to increase the heat dissipation area, which is widely adopted due to its simple process. The commonly used die-casting aluminum alloy is ADC12. Due to its good formability, it is suitable for making thin castings. However, due to its poor thermal conductivity (about 96 W/m.K), AA1070 aluminum is now mostly used as die-casting material in China, with a thermal conductivity of up to around 200 W/m.K, which has good heat dissipation effect. However, there are some inherent shortcomings that AA1070 aluminum alloy die-casting radiators cannot overcome on their own:
(1) Excessive surface flow patterns and oxidation slag during die casting can reduce the heat transfer effect.
(2) When cooling, the internal micro shrinkage pores are relatively high, and the actual thermal conductivity decreases (K<200 W/m.K).
(3) The mold is prone to erosion, resulting in a shorter lifespan.
(4) Poor formability, not suitable for thin castings.
(5) The material is soft and prone to deformation.
