WATER COOLING:

 

Water-cooled radiator has a water inlet and a water outlet, the internal heat sink a number of waterways, which can give full play to the water-cooled advantage, can take more heat. This is the basic principle of water cooled heat sink.

advantage

Because the number of the fan is reduced, the vibration and noise generated by the fan is reduced.

The cooling effect is much higher than that of the air cooling system.

classification

According to the principle of points

From the point of view of the principle of water cooling, it can be divided into two categories: active and passive. Active water except in with water-cooling radiator all accessories, in addition to installing a radiator fan to assist radiating to the cooling effect has been not a small improvement, the water for fever DIY overclocking players use. Passive water do not install the no cooling fan, rely on water cooling radiator to dissipate the heat, is the largest increase the number of fins to assist radiating, the water than active water cooling effect is poor, but can do completely mute effect, suitable for mainstream DIY OC users use.

According to the installation method

From the point of view of the installation of water, and can be divided into two types of built-in and external water cooling. For the internal water cooling, is mainly composed of a radiator, water pipe, a water pump, adequate water, which doomed the most water cooling system volume is larger, and requirements of the interior space of the enclosure enough Kuanyu. External water cooling radiator, because the cooling water tank and the water pump and other working elements are arranged outside the box, which not only reduces the space occupied by the cabinet, but also can obtain a better cooling effect.

Working principle

A water cooling (liquid cooling radiating system must has the following parts: the water-cooling block, liquid circulation, water pump, pipeline and water tank or change heat exchanger.

Composition of water cooling system

Composition of water cooling system

Water-cooling block is an internal left channel metal block, made of copper or aluminum, and contact with the CPU and the absorptive CPU heat, so this part of the role and air-cooled heat sink effect is the same, the difference is the water-cooling block must leave through a circulating liquid channel and is completely sealed, so as to ensure circulating liquid leakage caused by electrical short-circuit.

The effect of circulating liquid is similar to that of air, but it can absorb a lot of heat and keep the temperature not change. If the liquid is water, it is the water cooling system that we all know.

The role of the pump is to promote the circulating fluid flow, so that the absorption of the CPU heat of the liquid will flow out of the water from the CPU block, and the new low temperature of the circulating liquid will continue to absorb the heat of CPU.

Water pipe is connected with the water pump, a water block and the water tank, and its role is let liquid circulation in a closed channel circulation flow and no leakage, so as to make the normal work of the liquid cooling system.

Water tank for storing liquid circulation, circulating liquid here release out of the CPU heat, low temperature of the circulating fluid to flow into the pipe, if less CPU heating power, the use of stored in the water tank of large capacity circulating liquid can ensure the circulating liquid temperature does not have obvious rise, such as fruit CPU power is large, you need to join for heat exchanger to help distribute the CPU heat, here for heat exchanger is a similar heat sink things, liquid circulation will transfer heat to the heat sink with large surface area, the cooling fan will flow into the air heat away.

If it is a small closed type cooling system, can omit open water tank liquid in the pump, a water-cooling block and heat exchanger between the round-trip flow to avoid liquid circulation exposed in the air and metamorphic.

Development history

When it comes to CPU water cooling that goes back to the last century, as early as 1998, 1999 or so Taiwan began to pop CPU water cooling, DIY use their own conditions to produce a wide variety of water cooling system

CPU water cooling

CPU water cooling

System, but mostly to open structure based, in the DIY view, when the CPU is already a huge heat of the monster.

Continental water production is relatively late, are mostly concentrated in the individual production level, once appear like Hangzhou Zhongyu Coolmax several personal production and sales of water products, including Coolmax water-cooling have decent packaging and accessories, in the propaganda also had action, but due to the limited market response, these products like clouds, isn't a long time is from the market disappeared completely.

By 2003, the water began to flourish in the mainland market, which to the regular factory Aucma and individual making water king mainstream, from two aspects of the Forum promotion, marketing and launched a water made a new chapter.

A new generation of water compared with the old water principle does not change, but the production process is greatly improved, most focus on the design of full closed, and the mainland and Hong Kong and Taiwan personal DIY works between less and less, and the promotion of the Internet are not unrelated, the water in the last century is mainly concentrated in a few Internet fancier, with the popularity of the Internet, more and more experts in different fields have emerged, far across the computer industry and other related industries, proficient in metal processing production of the water-cooling radiator friends be too numerous to enumerate, more convenient, and more beautiful, practical and reliable, in addition, more and more friends can love water each one airs his own views in various forums so, also contributed to the progress of water cooling process is obviously, the Internet promotes the progress of water products, but also for the products Promotion laid the foundation.

With the rapid development of graphics technology, the graphics card on the GPU has been able to issue a considerable heat and CPU, so the water is no longer limited to the CPU, graphics cards, Beiqiao, hard disk
