Improving the heat dissipation efficiency of aluminum radiators can be achieved by designing the Aluminum Heat Sink reasonably, which can increase the fin density, shape, area, size specifications, and maximize the heat dissipation area A streamlined design can be adopted, and materials with high thermal conductivity, such as aluminum alloy and copper alloy, can be selected to improve the thermal conductivity efficiency of the radiator. Choosing materials with high thermal conductivity, such as aluminum alloys and copper alloys, can improve the thermal conductivity efficiency of Aluminum Heat Sink. Combine heat pipes with aluminum radiators. Heat pipes have extremely high thermal conductivity and can quickly transfer heat from the heat source to the far end of the Aluminum Heat Sink, effectively improving heat dissipation uniformity and efficiency.

1.By experimentally measuring the thermal resistance of Heat Sink under given conditions, the smaller the thermal resistance, the higher the heat dissipation efficiency of Heat Sink. 2. Heat transfer coefficient, meaning heat transfer coefficient, is the ratio of the amount of heat passing through the Heat Sink per unit time to the surface area of the Heat Sink. The larger the heat transfer coefficient, the stronger the ability of the radiator to transfer heat at a unit temperature difference, and the higher the heat dissipation efficiency. 3. Thermal conductivity and thermal diffusivity, the heat transfer coefficient of Heat Sink is determined through experiments, which represents the ratio of the heat transferred through the radiator per unit time and per unit area to the temperature difference. Thermal diffusivity refers to the product of the amount of heat that a material can diffuse per unit time, the unit area, thickness, and temperature difference of the material. The larger the heat transfer coefficient, the stronger the ability of Heat Sink to transfer heat at a unit temperature difference, and the higher the heat dissipation efficiency 4. Evaluation of material thermal conductivity: Although aluminum itself has good thermal conductivity, the thermal conductivity of aluminum with different purities and alloy compositions may also vary. You can understand the thermal conductivity of the aluminum material used by consulting the material specifications or conducting material thermal conductivity tests, and compare it with the standard value to evaluate its impact on heat dissipation efficiency.

1. The quality of the heat sink material (purity, thickness, processing accuracy, etc.) and manufacturing process (surface cracks, shrinkage holes, etc. caused by extrusion), as well as the poor quality of the material and the rough and defective process will directly affect the thermal conductivity of the aluminum profile heat sink; 2.The surface roughness and flatness of the aluminum profile heat sink contacting the mesa directly affect the contact thermal resistance and pressure drop; 3. Heat dissipation area of aluminum profile heat sink fins.

The production process is divided into three steps. The first step:make mold, extrusion aluminum profile, and aging. The second step:to use a CNC machining center to process milling, turning ,drilling, tapping, and chamfering. The final step : surface treatment.

Aluminum heat sinks need surface treatment to improve their thermal performance and protect them from corrosion. The surface treatment can include anodizing, chemical conversion coating, or painting. Anodizing creates a protective layer of aluminum oxide on the surface, which enhances the heat transfer by improving the surface emissivity and reflectivity. Chemical conversion coating also creates a protective layer on the surface, which improves the heat transfer and prevents corrosion. Painting can provide additional protection against corrosion and improve the aesthetics of the heat sink. Overall, surface treatment is necessary to ensure the longevity and effectiveness of aluminum heat sinks in various applications.

There are several surface treatments available for aluminum extrusion heat sinks, including anodizing, powder coating, painting, sandblasting,electroplate,Electrophoretic coating and polishing.

It is speculated that the aluminization limit will reach 30% - 50% or more in the future. The consumption of aluminum profiles for new energy vehicles will increase with the increase of the output of various types of vehicles, which will provide a broad market and development opportunities for China's aluminum extrusion industry.

Aluminum extrusion is the process of putting aluminum alloy into the extrusion cylinder and applying certain pressure to make it flow out of the specific die hole to obtain the required section shape and size. This method has low cost, high efficiency and simple operation. It occupies a considerable proportion in the industrial development and production management system of modern enterprises, making aluminum profiles an important basic research material in China's national economy. The extrusion of aluminum profiles shall be carried out according to the following process flow: Preparation before aluminum extrusion: Check the fuel system? Check the pneumatic system? Check wiring and power supply? Check the water circulation system? Check the number of aluminum bars and mold model. 1. Carefully check whether the fuel system design of each extrusion production line can supply normally; 2. Carefully check whether the air pressure system supplies gas normally, and record the flow and air pressure values; 3. Carefully check whether the circuit and power supply facilities are normal and whether the voltage is within the stable range of 380V; 4. Carefully check whether the cooling circulating water system design is open, and whether the water pressure and flow management are within the specified time range; 5. Count the raw materials and carefully check whether the number of aluminum bars is consistent with the mold model. Start steps of aluminum extrusion work: The aluminum bar material is paved → 12 aluminum bars are heated at one time → the temperature can reach 480 ℃ and heat preservation for 1h → the mold design is heated to 480 ℃ → the mold product is put into the standard mold base → the feeding port → extrusion → traction → straightening → aging → discharging → insulation for 2h after 200 ℃ → cooling → completion. 1. Put the prepared aluminum rods on the shelf, and leave a certain gap between the aluminum rods. Pay attention not to stack the aluminum rods, otherwise it will increase the difficulty of the extruder and easily cause aluminum alloy during operation. The staff was injured when the rod fell; 2. Operate in strict accordance with the process flow, put 12 aluminum rods into the furnace and heat them at room temperature. The heating time reaches 3.5 hours, the temperature reaches 480 ℃, and the normal production can be started after holding for 1 hour; 3. At the same time, put the extrusion die into the furnace for heating to make the die temperature reach 480 ° C; 4. After the aluminum rod and mold are heated and insulated, put the mold into the mold base of the extruder and prepare it; 5. Put the cut aluminum bar material into the raw material of the extruder for entry and prepare for extrusion; 6. Enter the extrusion stage. After the extruded profile comes out of the outlet, it is pulled by the tractor to determine the length and size for cutting, and then the aluminum profile is sent to the calibration platform for straightening. Then the aluminum profile can be transported to the finished product area for cutting to length. 7. Load the cut aluminum profile into the rack as required, transport it to the aging zone, and enter the aging furnace for aging treatment. When the aging temperature reaches 200 ℃, keep it for 2 hours, and then wait for the furnace to be discharged; After aging, it can be discharged. In the cooling stage, it can be cooled naturally or through cooling fans. So far, the staff of the extrusion enterprise has completed the extrusion of aluminum profiles with qualified appearance design quality and shape and size.

1) Durable The corrosion resistance and weathering resistance of aluminum is one of its remarkable advantages. Aluminum will naturally rust and resist corrosion without additional treatment. Because there is a thin layer of alumina protective film formed in natural environment between its surfaces. Anodizing improves corrosion resistance. 2) Light and strong Aluminum is more than 33% lighter than steel, while retaining most of its strength. The influence range of tensile strength of most aluminum alloys studied is generally about 70-700 MPa, and the density is two thirds lower than that of steel. Product design engineers do not have to worry about the extrusion strength of aluminum profiles. They can be used as structural members in the construction industry and the automobile industry, and are good substitutes for other metal materials. In order to reduce weight and energy consumption, aluminum alloy is widely used in the automobile industry. 3) Good thermal conductivity The thermal conductivity of aluminum is very similar to that of copper, but it is much lighter. Aluminum is a thermal conductor. The profile of aluminum profile can greatly improve the heat transfer surface area and thermal channel. 4) Stylish appearance Extruded aluminum can be painted, plated, polished and anodized, providing engineers with a wider range of appearance options than other materials. 5) Wide application range Basically, no cross section shape can be formed by aluminum extrusion, so the application and research scope of aluminum extrusion is very wide. Engineers can meet the requirements of different development and application market environments of enterprises according to different cross sections of design methods. 6) Easy for secondary processing Aluminum profiles can be easily formed, cut, drilled, machined, stamped, bent and welded to suit specific applications. 7) Short extrusion mold processing cycle and low cost Aluminum extrusion die is simple, short processing cycle and low cost. 8) Absorb shock and deformation In buildings, aluminum profiles can resist the deformation caused by weather and construction movement. In transportation vehicles, culture shock energy can be absorbed. Aluminum profiles maintain strength and flexibility under load and impact rebound. 9) Environmental protection Aluminum is an environmentally friendly material that is easy to recycle. Aluminum is the metal of the future. It is not only environmentally friendly, light weight, natural corrosion resistance, high strength, but also has good thermal conductivity and conductivity.
