How to choose an approriate CPU cooler for IPC?
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 control to shut down, even worse the CPU may be burned out, the CPU plays a decisive role in the industrial control equipment operation, so the cooling system is crucial for the IPC operation.
Industrial computer CPU heat sink can be divided into air cooled heat sink, and liquid cooling heat sink, the heat sink type is selected based on the actual requirements.
1, air cooling heat sink
Air cooled heat sink is the most widespread used in industrial control computer, which usually includes a cooling fan and a heat sink. The 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 CPU use different radiators. For example, AMD CPU and INTEL CPU use different radiators, and INTEL 478-pin CPUs use different heat sinks from INTEL 775-pin CPUs. For high power device, heat pipes and vapor chamber are usually applied to improve the thermal performance.
2, Liquid cooling heat sink
The liquid cooling radiator take away the heat by the liquid flowing under the drive of the pump. Compared with air cooling, it has the advantages of quietness, stable cooling and less dependence on the environment. But it's more complex and expensive.
How to select an approriate CPU heat sink?
1､Fan power
In general, the fan has higher power, it will generate stronger air flow, and will has better heat dissipation performance.
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. However, the extremely high speed will generate heat and increase the wear of the fan, so it needs a balance between the two aspects.
3､Material of heat sink
The radiator is widely used aluminum alloy due to it has low price and good heat dissipation effect as the heat sink. In order to improve the overall heat dissipation effect of the heat sink, the medium and high-end heat sinks use the copper to conduct the CPU as copper has better thermal conducitivy than aluminum .
4. Fan noise
It refers to the sound made by the fan of the industrial computer during the working process, which is mainly affected by the fan bearings and blades.
5. Fan exhaust air volume
The air volume of the fan is an important indicator to measure the performance of a fan. The angle of the fan blades and the speed of the fan are all determinants that affect the air volume of the cooling fan.
