The heat generation of the industrial computer is mainly a large amount of heat generated by the high-speed operation of the CPU. Generally, the heat dissipation method of the fan is used to dissipate a large amount of heat to the outside of the chassis through the fan.
This cooling method is simple and efficient, but there is a disadvantage that after the computer has been in operation for a long time, there will be a thick layer of dust and soot on the fan and motherboard. What GOOIPC shares with you today is:

The industrial computer is equipped with a fan to dissipate heat. Why is the heat dissipation performance still poor?

  1. Identify the heat dissipation direction of the industrial computer
    The side of the industrial computer fan without beams is the air inlet, and the side with beams and wires is the air outlet. When operating, the side of the front panel fan with beams and wires should face into the case, and the side of the top and rear fans with beams and wires should face out of the case.
  2. With the addition of a fan, the heat dissipation performance of the host computer has not improved but has become worse.
    Most of the reasons for this situation are that the direction of the fan is installed in reverse.
    Nowadays, the side panels of mainstream chassis like to use transparent materials. Generally, only the front, top and back have large-area cooling holes. The back exhausts the hot air, and the installation of a fan is to accelerate the air circulation in the chassis to improve the cooling efficiency.
    If the direction of the fan is installed in reverse, it will cause the air duct in the chassis to be disordered, and the CPU and graphics card of the industrial computer are more likely to overheat.

Generally speaking, after installing the fan correctly, you will find that the temperature of the industrial computer chassis has dropped significantly, and the problem of high temperature of the host computer can be easily solved. In addition, the blowing direction of the radiator fan also affects the heat dissipation of the chassis.
The side-blowing radiator has a larger cooling fin area, more heat pipes, and a better cooling effect with the fan. Therefore, most air-cooled radiators on the market adopt the side-blowing design. If you use a water-cooled radiator, you need to pay attention to the blowing direction of the cooling fan, which will be determined according to the installation position of the cooling fan.

This small industrial computer is mainly designed with a fanless cooling system. This design method has the ability to resist dust, smoke, signal and other interference.
The heat dissipation design of the industrial computer still needs to be considered from the customer’s use environment. Therefore, more efforts are needed in the design.
