There are all types of mechanical devices, electronic and electrical radiators, and different aluminum radiator profiles
have different advantages and disadvantages and play different roles.
1. Extruded aluminum profile: Fins and substrate are integrated. Without splicing, the heat conduction inside the radiator is uniform and the thermal conductivity is high. The disadvantage is that it is limited by the extrusion process, and the profile size and fin spacing, thickness and plate height are limited.
2. Semi-extruded aluminum profile, semi-embedded: Due to the technological limitations of extruded aluminum profile, the spacing of the plate should not be too narrow, and the aluminum plate is firmly fixed between the two plates by inserting and pressing. Because half of the fins are inserted, and the aluminum plate is not integrated with the bottom plate, the heat transfer efficiency of the insert is not as good as the integration. The heat resistance is greater than that of pure extruded aluminum. The radiator reduces the cross-section size of the profile through the extrusion process of the aluminum radiator profiles, and the extruded aluminium profiles cannot be processed into radiator products.
3. Fin splicing type: Make the fins first, then stack the fins on top of each other, press them through pressure treatment, and bind the parts tightly together. The process can be used for aluminum radiator profiles of any width and height. The disadvantage is that the fins and fins are separated, the thermal resistance is large, and the thermal conductivity is greatly reduced.
4. Insert type: Consists of a base plate and a plurality of heat sinks. First the side of the blade is milled into the blade slot and one end of the fin is inserted into the slot and pressed. In this type of aluminum radiator profiles, only a small part of the end of the aluminum is inserted into the bottom plate. The contact thermal conductivity area is limited, the thermal resistance is too large, and the consistency of the thermal resistance parameters is poor. The method is not limited to any size process radiator, simple processing, market price has a comparative advantage.
