At present, extruded aluminum profiles are commonly used to make radiators on the market. The cooling fins can be made very thin, and the heat dissipation area can be expanded to the greatest extent. When the cooling fins work, air convection is automatically formed to diffuse heat, and the heat dissipation effect is very good. The radiator aluminum profiles are mainly sunflower shapes, flat wide shapes, round shapes, comb shapes, fishbone shapes, fin shapes, and so on.
The sunflower shape of the radiator can increase the contact between the heat sink and the air so that it can receive the airflow more evenly and smoothly, and take away the heat more evenly. This kind of heat dissipation effect is very fast and the effect is quite obvious, which is very suitable for new components to dissipate heat. Sunflower aluminum radiators are widely used in inverters, new energy, power electronics, communications, and other fields.

About Aluminum Extrusion Radiator Profiles
Aluminum extrusion radiator profiles: Aluminum alloys are widely used in radiator materials because of their lightweight and beautiful appearance, good thermal conductivity, and easy processing into complex shapes. There are three main types of aluminum alloy radiator materials: flat and wide, comb-shaped or fishbone; round or oval with radial and dendritic fins. Their common features are: the distance between the heat sinks is short, a groove is formed between two adjacent heat sinks, and its aspect ratio is large; the wall thickness difference is large, the heat sink is generally thin, and the bottom plate at the root is thicker, It brings great difficulty to the mold design, manufacture and production of radiator profiles.
Some of the radiator profiles are smaller in size and symmetrical in shape, which is easier to produce. Most of the radiator profiles are flat and wide, with large dimensions, some are asymmetrical, and the grooves between the fins have a large aspect ratio. Its production is difficult. It is necessary to cooperate from ingot casting, die, and extrusion processes to successfully produce radiator profiles. The alloy used for extruding radiator profiles must have good extrudability and thermal conductivity, usually 6063 alloy material, which has good extrudability, thermal conductivity, and good mechanical properties.
The production of aluminum alloy radiator profiles should start from the quality of the ingot, the material and design of the mold, the reduction of the extrusion force, and the extrusion process.
Requirements for ingot quality:
The alloy composition of the ingot should strictly control the impurity content to ensure the purity of the alloy composition. For the 6063 alloys, the content of Fe, Mg, and Si should be controlled. The Fe content should be less than 0.2%, the content of Mg and Si are generally controlled at the lower limit of the national standard, the content of Mg is 0.45%-0.55%, and the content of Si is 0.25%-0.35%. The organization and performance are uniforms.
The surface of the ingot should be smooth, no segregation tumor or sticky sand and mud is allowed. The end face of the ingot should be flat, and it should not be cut into steps or too steep. Because the step shape or the inclination of the cut is too large, when extruding the heat dissipation profile with a flat die, if there is no design guide, the ingot directly touches the mold. If the stress is too concentrated, it is easy to break the tooth shape of the mold or cause the discharge sequence to be different, and it is easy to block the mold or the extrusion molding is not good.
Requirements for the mold:
Because the molds of the radiator profiles are made of many slender teeth, they must bear a large extrusion force, and each tooth must have high strength and toughness. Those teeth with poor strength or toughness are prone to fracture, so the quality of the die steel must be reliable.
For the radiator profile to be successfully extruded, the key is to design the mold reasonably, manufacture it accurately, and avoid the ingot being directly extruded onto the mold working belt.
For a section with a relatively mature design, it is also a good method to use an inlaid alloy steel mold, because the alloy steel mold has better rigidity and wear resistance, and is not easy to deform, which is conducive to the forming of the radiator profile.
Reduce squeezing force:
To prevent the broken teeth of the die, the extrusion force should be reduced as much as possible, and the extrusion force is related to the length of the ingot, the deformation resistance of the alloy, the state of the ingot, and the degree of deformation. It should not be too long, about 0.6~0.85 times the normal cast rod, especially when trying out the mold and extruding the first cast rod, to ensure the smooth production of qualified products, it is best to use a shorter cast rod to test mold.
Extrusion process: The key to the production of radiator profiles is the first trial of the extrusion die. If conditions permit, you can first do a simulation test on the computer to see if the working belt of the die design is reasonable, and then try the die on the extruder. . The first mold trial is extremely important. The operator should let the main plunger move forward and move slowly at a low pressure lower than 8MPa. It is best to have someone watch the exit of the mold with a torch light and wait for each extrusion to die. After a heat sink is uniformly extruded into the die hole, the extrusion can be gradually accelerated and accelerated. When continuing to extrude after a successful mold trial, attention should be paid to controlling the extrusion strength to achieve smooth operation. When producing radiator profiles, attention should be paid to the heating temperature of the mold, and the mold temperature should be close to the ingot temperature. If the temperature difference is too large, the temperature of the metal will drop due to the slow extrusion speed during the upper pressure, and the phenomenon of die blockage or uneven flow rate will easily occur.
What are the advantages of CNC machining aluminum radiators?
