Tungsten Copper Heat Sink Used for CPU

Introduction

CPU will produce a lot of heat when it is working, if not timely disseminate the heat out, it is easy to lead to poor computer operation, or even burn the CPU. Tungsten copper heat sink used for CPU can cool it down and keep working stability.

Type

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.

Comparison

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 (Many copper heat sink have exceeded the CPU's weight limit), but easy to oxidize. And aluminum is not sufficient in hardness and not good as copper in thermal conductivity. Some radiators to take advantage of each other, in the aluminum radiator base embedded in a tungsten copper plate.
