High conductivity and high heat dissipation are then passed through a high-precision imported CNC machining center to ensure high dimensional accuracy and more stability, stable performance and easy surface treatment. According to the measurement, the heat dissipation performance of pure aluminum cold forging is 2 times higher than that of the same type of die-casting products, and 1 times higher than that of the same type of aluminum profile car products. It is the best solution for heat dissipation of high-power LED lighting.

Good thermal conductivity

The cold forged heat sink can be extruded in one piece with pure aluminum AL1070 and 1050. The thermal conductivity of pure aluminum AL1070 is 226w/m.k, the thermal conductivity of alloy aluminum 6063 is 180W/m.k, while the thermal conductivity of ordinary die-cast aluminum A380 is only 96W/m.k. The larger the thermal conductivity, the faster the heat released by the LED can be conducted. It is beneficial to the overall heat dissipation of LED lights.

Good heat dissipation structure

The cold forged heat sink base plate and fins are integrally formed without any gap between them. The heat of the base plate can be conducted to the cooling fins without any obstruction. As for the aluminum parts of the car and the brazed parts, the heat dissipation bottom plate and the heat sink are riveted or brazed together after machining, and there must be a gap between them; indirect thermal resistance is generated, and the thermal expansion during the use of the lamp Cold shrinkage will also lead to the generation and enlargement of the gap, which will increase the thermal resistance, which is not conducive to the conduction of heat.

Large heat dissipation area

The thickness of the cooling fins of the cold forged radiator can be 0.7mm, and the spacing can be 1mm. The thin and many cooling fins greatly increase the contact area of the air, which is more conducive to air convection heat dissipation.

Variety of fins

The cold forging process can meet various shapes of fins such as cylinder, sheet, square column, hexagonal column, etc.

Small size and light weight

Compared with die-casting parts, car aluminum parts and brazing parts, pure aluminum cold forging radiators have the above advantages, and the same volume and shape can be used for heat dissipation of higher-power lamps (such as traditional 5w radiators, the same volume and shape. The pure aluminum forging radiator can do 7w). Therefore, the use of pure aluminum cold forging heat sinks will reduce the weight and volume of LED lamps, reduce the requirements for shapes such as lamp posts, reduce the overall cost, and make the products more competitive.

Applied to light source heat sinks and LED heat sinks in green house.
