    Custom aluminum extruded radiator

    Aluminum alloy is widely used in the production of cooling equipment because of its light weight, beautiful appearance, good ease of processing into complex shapes.

    Advantages of extruded aluminum radiator materials:

    1. Resonance coefficient

    Aluminum has three times the heat dissipation capacity of steel;The resonance coefficient of aluminum is 167W/mK, and that of steel is 50W/mKM.K is temperature.

    Resonance coefficient is defined as: how much W energy can be transmitted per unit length and per K.The integral of the value, the better the conversion rate.

    We can see that aluminum has three times the resonant coefficient of steel, which means that aluminum has three times the resonant coefficient of steel.

    2. Thermal strength of metal:

    The metal thermal strength of aluminum is 2.277W/Kg℃.Cast iron: 0.4w/Kg℃;Steel: 0.76 W/Kg℃;Copper and aluminum: 1.728w/Kg℃;

    These instructions: aluminum extrusion radiator, mutual heat dissipation is good, its inherent coefficient, pressure resistance, metal thermal strength is also very good;

    3. Aesthetics and Decoration:

    Aluminum heat dissipation large, fast heat dissipation, high efficiency is the biggest characteristics of aluminum radiator;

    The appearance of electrostatic spraying, colorful, decorative good.

    Heat dissipation is four times of casting Angle, light weight is one tenth of cast iron, beautiful and generous, small space, environmental protection and energy saving.

    4. Production:

    From the point of view of manufacturing radiator, aluminum alloy is the best choice material for manufacturing radiator, with advantages in energy saving, material saving, decoration, price, weight and so on.Copper aluminum, steel aluminum, stainless steel aluminum and aluminum composite products contain aluminum components

    5. Corrosion protection:

    Steel is phosphated prior to the tedious process of corrosion, whereas aluminum alloys are oxidized or directly corroded.

    There are three main types of aluminum radiators or aluminum extruded radiators:

    1. General and wide, or fish bone comb;

    2. Round or oval;

    3. Branch shape;

    Aluminum radiator has its own characteristics: the distance between the radiators is short, two adjacent radiators form a slit, the ratio of length and width is large;Due to the complex shape of radiator extruded profiles, design, manufacture and production are very difficult.The mold.

    If you design heat sinks, we can help you make them.We have first-class extrusion equipment and professional staff, can provide you with the aluminum radiator, surface finish and secondary processing.Maintain good quality while saving production cost.

    Extruded aluminum is one of the most popular and cost-effective methods of radiator manufacturing.

    Basic concept of thermal extrusion

    The heating temperature of the thermal extrusion process is higher than that of the blank metal and is under triple pressure, so many materials can be hot extruded.

    During the extrusion process, the blank is put into the extrusion bucket.Under the action of the extrusion rod, when the pressure exceeds the stress of the material, it will deform the shape of the forging through the die hole.And hot and cold extrusion deformation, but the mold requirements are high, hot parts of the surface volume is also large.

    Extruded heat sink: The aluminum extrusion manufacturer prepares the mold, heats the aluminum ingot to a certain temperature, changes its physical form, and then takes out the mold to replace the heat sink material we want;Can be used for cutting, slotting, grinding, deburring, cleaning, surface treatment.

    Standard extruded radiators are pre-cut and finished radiators and usually include installation fittings.Standard extruded radiators include flat backs, double sided radiators with clearances or extruded parts normally cooled at plate level.

    The shapes of extruded fins range from simple planar dorsal fin structures to complex geometric shapes, of which 6063 alloy is the most commonly used aluminum alloy with high thermal conductivity.

    We can provide customized surface treatment (anodic oxidation) on request for specific application requirements, as well as a variety of auxiliary metal manufacturing services, including precision cutting, milling, stamping, extrusion and grooving.


    1. Aluminum profiles are the most cost-effective solution for most electronic cooling applications;

    2. Aluminum alloy 6063;

    3. Comply with RoHS;

    4. Extruded profiles adopt straight fins to ensure the best performance for specific heat dissipation applications;
