It is a common phenomenon that the computer surface becomes hot after using a while. This is because the CPU generates a lot of heat when working. If does not dissipate in time, it will cause a crash. The CPU heat sink is used to dissipate heat and the heat sink plays a decisive role in the stable operation of the CPU. This article describes the classification of the heatsink for cpu to help you better choose the heat sink.
The water-cooled heat sink is a kind of heat sink with coolant as the medium. Usually we can divide it into two types: integrated water-cooling and split water-cooling according to the installation method.
The main structure of the integrated water-cooled heat sink consists of three parts: cold head, cold row and fan. The cold head is responsible for absorbing the heat emitted by the CPU. The water pump in the cold head provides the power of the cold liquid flow; the cold discharge dissipates the heat absorbed by the cold liquid to the outside of the chassis; the fan is responsible for accelerating the air flow speed and improving the heat dissipation efficiency.
Split type water cooling is excellent in terms of color value and heat dissipation efficiency because of high cost. Split-type water cooling also provides the cooling of the graphics card for water cooling, so the value is even more obvious.
Heat-free air-cooled heat sinks --- These heat sinks rely entirely on metal and air flow for heat transfer, with low efficiency and unsatisfactory noise. Except for some occasions that pursue extreme space pressing, in most cases, the temperature of the CPU cannot be suppressed.
The heat pipe heat sink uses a heat pipe and a refrigerant sealed therein for heat transfer, and generally consists of a base, a heat pipe, a fin, and a fan. It can be divided into two types according to the fan wind direction: down pressure type and tower type.
The fan of the push-down heat sink is located at the top of the heat sink, and the air moves from top to bottom. The air passes through the fan and the fin and is blocked by the main board, and begins to spread to the surroundings. The advantages of the push-down structure are very obvious. Its low height can be applied to a variety of space-constrained chassis. In addition, because the air flow is blocked by the main board and spreads around, it can also help the components around the CPU to dissipate heat, such as power supply and RAM.
The tower structure air-cooled heat sink is the mainstream form of the heat sink on the whole market. It is also composed of a base, a heat pipe, a fin, and a fan. The tower heat sink works in the same way and under the same pressure as the down-pressure heat sink, but it solves several disadvantages of the down-pressure heat sink. No matter which direction is blown, it can perfectly match the chassis to build the air duct; at the same time, the tower structure can also bring more space for placing fins and heat pipes to improve heat dissipation efficiency.
The above is the classification of CPU heat sink. If this article is helpful to you, please forward it to more people in need.
