The air volume is closely related to the size and speed of the fan. The larger the fan, the higher the speed.
The greater the air volume, the better the heat dissipation effect. Therefore, when we choose water cooling
You will often see a row of options like this:
The numbers 120, 240, 360 are in millimeters (mm) and refer to the
The length of the fans when arranged horizontally.
A 120mm radiator means a fan with a length of 120mm.
240 radiator does not mean that there is a fan with a width of 240mm, but that
There are two fans with a length of 120mm.
360 radiator refers to a radiator with three fans of 120mm in length.
Wind pressure (i.e. the pressure difference between the fan outlet and the fan inlet) can also be understood as the pressure generated by the movement of the fluid, which is also the velocity of the fluid. Static pressure: the degree of pressure on the surface of the fluid when it is stationary .
The contents involved in air volume and air pressure are quite complicated.
Simply understand:
Wind volume indicates how strong the wind is.
Wind pressure indicates how far the wind can blow
Factors that determine air volume and wind pressure:
1. Excellent frame and blade shape, in line with fluid mechanics.
2. How fast the fan blades rotate.
The amount of water pumped and the speed of water flow
1. Flow rate : The flow rate of a water pump is also called the water delivery volume, which refers to the amount of water delivered by the water pump per unit time. It is represented by the symbol Q, and its unit is liter/second, cubic meter/second, cubic meter/hour.
2. Lift The lift of a pump refers to the height to which the pump can lift water, usually represented by the symbol H.
It is expressed in meters.
The pump head and flow rate are directly related to the cavity design, impeller design, and motor speed.
It is not difficult to analyze from the working principle of water cooling radiator that the larger the water volume and the faster the water flow, the better the heat dissipation effect. There are three main aspects that affect them:
They are: the size of the water cooling radiator, the thickness and length of the water cooling pipe, and the strength of the water pump.
High-density EPDM water pipe, EPDM is a terpolymer of ethylene, propylene and non-conjugated dienes, also known as terpolymer EPDM in Chinese, which is a type of EPDM rubber. It has excellent aging resistance such as ozone resistance, heat resistance, and weather resistance, and can be widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, heat-resistant hoses, tapes, automotive seals, etc. Imported high-quality rubber ensures tightness and no leakage.
Water cooling radiators are quieter and have stronger heat dissipation capabilities;
First, let’s analyze it from the perspective of “quieter”:
The noise source of air-cooled radiators is mostly the sound made when the fan rotates. The greater the heat, the faster the fan rotates, and the louder the noise.
The noise sources of water-cooled radiators are mainly fans and water pumps. Theoretically, if we only look at the fan, the heat capacity of water is larger, and the heat load capacity of the water-cooled refrigeration system is stronger. If the same amount of heat is dissipated, the fan speed will be lower than that of air cooling, and the noise will also be lower.
advantage:
1. The pump head noise is smaller than the tower air cooling of the same price. For example, if the wind
The cooling can be suppressed to 60 degrees and needs to run at 3000RPM. Water cooling only needs to run to
1500RPM can suppress the temperature to 60 degrees or even higher;
2. Water cooling has stronger heat load capacity;
shortcoming:
1. Limited by the physical conditions of the chassis
2. There is a risk of leakage.
Small Cooling Fans play an indispensable role in modern technology products. It is mainly used to help various electronic equipment
