As the core working frequency of the graphics card and the working frequency of the video memory continue to rise, the heat of the graphics card chip also increases rapidly. The number of transistors in the display chip has reached, or even exceeded the number in the CPU, so high integration is bound to bring the increase of heat, in order to solve these problems, the graphics card will use the necessary heat dissipation. Especially for overclocking enthusiasts and users who need to work long hours, excellent cooling method is a must for selecting a video card.

The heat dissipation mode of the graphics card is divided into the form of heat sink and heat sink with the fan, also known as active heat dissipation and passive heat dissipation. Generally, some graphics cards with low working frequency use passive heat dissipation. This heat dissipation method is to install a heat sink on the display chip, and there is no need for a heat dissipation fan. Because the low frequency of the graphics card heat dissipation is not very large, there is no need to use cooling fans, so in order to ensure the stable work of the graphics card at the same time, not only can reduce the cost, but also reduce the noise in use.

Heat pipe has high heat conduction performance. Compared with metal, heat pipe can transfer several orders of magnitude more heat per unit mass, and has excellent isothermal and thermal switching performance, especially suitable for high precision heat dissipation environment. It is worth noting that heat pipe is only a high efficiency heat transfer technology, and can not dissipate heat itself. It must be combined with cooling devices such as heat sink or fan at the condensing end to dissipate heat eventually. The use of heat pipe heat dissipation of the graphics card is also more and more.

The characteristics of heat pipe thermal module：

Heat pipe radiator is a new product which makes great improvement to many old heat sink or heat exchange product and system by using heat pipe technology and principle.

The advantage of heat pipe thermal module：

Heat pipe self-cooling cooling system without fan, no noise, maintenance free, safe and reliable, heat pipe air cooling and even self-cooling can replace water cooling system, saving water resources and related auxiliary equipment investment, in addition, heat pipe heat dissipation can also concentrate the heating parts, even sealed, and the heat dissipation part of the outside or far away, dust, moisture, explosion proof. Improve the safety, reliability and application range of electrical equipment, heat pipe radiator than solid radiator performance can be improved by more than 10 times.

The disadvantage of heat pipe thermal module：

Copper surface is susceptible to natural oxidation.

Material costs are high.
