Large Aluminum Extruded Radiator

Product introduction

The high-power aluminum extrusion radiator is mainly made of aluminum alloy material and formed by extrusion process. Its basic structure usually includes two parts: heat fin and base. The cooling fins have a sheet-like structure and are closely arranged on the base to form a large cooling area. The base is in close contact with the heat source, and the heat is quickly transmitted to the entire radiator. This structural design allows the radiator to take full advantage of the natural or forced convection of air to dissipate heat to the surrounding environment, thus ensuring the operation of high-power electronic equipment within the normal operating temperature range.

Material property

Aluminum alloy is the material of choice for high-power aluminum extrusion radiators, which is mainly due to its excellent series of characteristics. First of all, aluminum alloy has a high thermal conductivity, which can quickly conduct heat from the heat source to the various parts of the radiator, ensuring the rapid diffusion of heat. Secondly, the density of aluminum alloy is relatively low, compared with some other metal materials, under the premise of ensuring heat dissipation performance, making the weight of the radiator lighter, easy to install and use in some equipment with weight requirements, such as aerospace electronic equipment and mobile base station equipment. In addition, aluminum alloy also has good processing properties, easy to be formed into complex shapes by extrusion process, to meet the diverse needs of radiator structural design in different application scenarios. Moreover, the cost of aluminum alloy is relatively reasonable, and it has a high cost performance in large-scale production, which makes the high-power aluminum extrusion radiator can be applied and promoted in a wide range of market areas.

Heat dissipation advantage

Large area fins: The number of fins of the high-power aluminum extrusion radiator is large and closely arranged, which greatly increases the contact area with the air. When the heat is transferred to the fins, the flow of air between the fins can quickly carry away the heat and dissipate the heat to the surrounding environment through thermal convection. This large-area fin design makes the heat dissipation efficiency of the radiator significantly improved, and can effectively cope with the high heat load generated by high-power electronic equipment. For example, in a server, a large amount of heat generated by multiple cpus working at the same time can be rapidly dissipated through the heat fins of the aluminum extruded heat sink to ensure the stable running of the server and avoid problems such as crash or performance degradation caused by overheating.

Efficient heat transfer: Due to the high thermal conductivity of the aluminum alloy and the integral structure formed by the extrusion process, heat can be efficiently transmitted from the heating source to the entire radiator. The close contact between the base and the heat source ensures rapid heat transfer and reduces heat loss during conduction. This efficient heat conduction capability enables the radiator to respond to the temperature change of the heat source in time, quickly dissipate the heat, and maintain the temperature of the heat source in a relatively stable range, thereby improving the reliability and stability of the electronic equipment and extending its service life.

Adaptive heat dissipation method: The high-power aluminum extrusion radiator can use natural convection for heat dissipation, and can also be installed by auxiliary equipment such as fans to achieve forced convection heat dissipation. Under natural convection conditions, the radiator relies on the natural flow of the surrounding air to take away heat, this way is simple, low cost, suitable for some heat dissipation requirements are not particularly harsh and the ambient temperature is relatively low occasions. In the forced convection heat dissipation mode, the high-speed airflow generated by the fan can significantly enhance the heat exchange efficiency between the air and the heat dissipation fin, so that the radiator can cope with higher power density and more harsh ambient temperature conditions. The flexibility of this heat dissipation method enables the high-power aluminum extrusion heat sink to be widely used in a variety of different working environments and electronic devices.
