Tungsten Copper Heat Sink Used for Electronic Radiator

Tungsten copper heat sink used for electronic radiator is also called as tungsten copper radiator, which can take heat away and cool down without external power supply. According to different materials, it can be divided into:
 Aluminum-extruded heat sink: Aluminum purity is more than 98%, low density, good thermal conductivity and low costs;
Aluminum-casted heat sink: Soft texture, large cooling area, low production costs;
Copper and copper alloy cutting heat sink: In order to meet the constant heat dissipating capacity of CPU, it should use copper and copper alloy, which has higher hardness and better performance in thermal conductivity.

In terms of heat sink materials, each one has different thermal conductivity. According to the thermal conductivity of high to low is silver, copper, aluminum, and steel. However, the silver for the heat sink will be too expensive, the best solution for the use of copper. Although the aluminum is much cheaper, obviously is not as good thermal conductivity of copper and its alloys (only about 50% of copper). Commonly used heat sink material is copper alloy and aluminum alloy, both of them have advantages and disadvantages. Copper has better performance in thermal conductivity, but it has high cost, large in weight, but easy to oxidize. And aluminum is not sufficient in hardness and not good as copper in thermal conductivity.

In addition, tungsten copper heat sink also can be used for CPU can cool down and keep working stability. According to the way of cooling, tungsten copper heat sink for CPU can be divided into three types of air cooling, heat pipe and water cooling.
Air cooling: The most common type of heat sink, including a cooling fan and a heat sink. The principle is the heat generated by the CPU to the heat sink, and then through the fan to take away;
Heat pipe: It is a heat transfer element with extremely high thermal conductivity, which transfers heat by evaporation and condensation of the liquid in a fully enclosed vacuum tube. Most of these fans for the "air-cooled + heat pipe", both air-cooled and heat pipe advantages, with high heat dissipation;
Water cooling: The liquid forced by pump and take away the heat of radiator, compared with air cooling, it is more stable and less dependence to the environment.
