High-power Passive Cooling Solution

Advantages: Quickly moves the heat to the aluminum fins through the heat pipe, whose large surface area removes 35W heat flux, a well established and effective manufacturing process.


The mid-level graphics card heat dissipation solution, which transfers the heat from the heat pipe to the aluminum fins, in addition to quickly cooling the 110-watt heat source through a 9015 high volume fan.


This low-profile solution has the advantage of optimizing price and performance. It is an effective solution commonly used for mid-low-end graphics cards. The 35-watt heat source is quickly cooled through a 5010 high volume fan.


Aluminum extrusion is a kind of aluminum ingot in a semi-molten state that passes through a mold under high pressure to extrude a profile of the same shape as the mold.

Aluminum extrusion heat sink is currently the most popular main design method. Aluminum extrusion radiator aluminum extrusion die is relatively cheap, the construction method is mature and stable, and the extrusion surface can be made into complex shapes.


Stamped heat sinks are formed by stamping aluminum sheets, which are often used when the surrounding space is limited and parts need to be avoided.

Its bending method can increase the area across the surrounding parts, which is very suitable for applications under the trade-off between cost and performance.

Because of its design flexibility, the use of CNC methods can be reduced in avoidance.


The plated heat sink is made of flat surface by cutting or stamping.

Because of the shape of the sheet, it has a good advantage when the space height is limited.

At present, it is the largest major design method for TV and Netcom products.

When this radiator is sprayed with graphene, the radiation heat dissipation efficiency is more obvious than that of aluminum extrusion.
