The CPU of the industrial computer will generate a lot of heat when it is working. If the heat is not dissipated in time, it will cause the industrial computer to crash. The stable operation of the CPU plays a decisive role.
Industrial computer CPU radiators can be divided into air-cooled radiators, heat pipe radiators, and water-cooled radiators, which can be purchased according to actual needs. Next, let’s take a look at the classification, purchase and assembly of CPU radiators.
Classification of industrial computer CPU radiator
1. Air-cooled radiator
Air-cooled radiator This is the most common type of radiator now, including a cooling fan and a heat sink. Its principle is to transfer the heat generated by the CPU to the heat sink, and then take the heat away through the fan. It should be noted that, Different types and specifications of CPUs use different radiators, for example, AMD CPUs use different radiators from Intel CPUs, and CPUs with INTEL478 pins use different radiators than CPUs with INTEL775 pins.
2. Heat pipe radiator
The heat pipe radiator is a heat transfer element with extremely high thermal conductivity. The heat pipe radiator transfers heat through the evaporation and condensation of liquid in a fully enclosed vacuum tube. Most of its fans are air-cooled and heat pipe. Advantages of cold and heat pipes, with high heat dissipation.
3. Water-cooled radiator
The water-cooled radiator is driven by the pump to force the circulation of the liquid to take away the heat of the radiator. Compared with the air-cooled radiator, it has the advantages of quietness, stable cooling, and less dependence on the environment.
How to choose a suitable industrial computer CPU cooler
1. Fan power
Generally speaking, the greater the power, the stronger the wind force of the industrial computer fan, and the better the heat dissipation effect.
2. Fan speed
Under normal circumstances, the higher the speed of the fan, the greater the air volume it provides to the CPU, and the better the air convection effect. But extremely high speed will bring heat and increase the wear and tear of the fan, so it needs to be in between strike a balance.
3. Heat sink material
The heat sink widely uses aluminum alloy with low price and good heat dissipation effect as the heat sink. In order to improve the overall heat dissipation effect of the heat sink, medium and high-end heat sinks use copper medium with better heat dissipation effect in the place where the heat sink is in contact with the CPU heat dissipation core.
4. Fan noise
It refers to the sound made by the fan of the industrial computer during operation, which is mainly affected by the fan bearings and blades.
5. Fan exhaust volume
Fan exhaust volume is an important index to measure the performance of a fan. The angle of fan blades, fan speed, etc. are the determining factors affecting the exhaust air volume of cooling fans.
Assembly steps of CPU radiator for industrial computer
Due to the large heat generated by the CPU, it is very important to choose a heat sink with excellent heat dissipation performance, but if the heat sink is not installed properly, the heat dissipation effect will also be reduced.
Before installing the heat sink, we need to evenly coat a layer of thermal conductive silicone grease on the surface of the CPU.
When installing, align the four corners of the radiator with the corresponding positions on the main board, and then press down the four corner buckles firmly. Some radiators are designed with screws, so nuts must be placed at the corresponding positions on the back of the main board during installation. Due to industrial control The host has fool-proof settings, and the installation method is relatively simple.
After fixing the radiator, we need to connect the cooling fan to the power supply interface of the industrial control main board. Find the interface where the fan is installed on the industrial control main board, and insert the fan plug. Since the fan power plugs of the main board are all made of anti-corrosion The dumb design can not be inserted in the opposite direction, so it is quite convenient to install.
