Why do we need to use cabinet air conditioner

With the acceleration of the process of industrialization and the improvement of the degree of automation of various equipment, the use of sophisticated and complex electronic and electrical equipment such as servo amplifiers, PLCs, and inverters has become more and more widespread. These devices generate a lot of heat when they work, and they are more sensitive to high temperatures. When the temperature in the control cabinet is higher than 40°C for a long time, it will affect the stability and life of the control equipment.

The usual solution is to install an exhaust fan on the control cabinet to cool down, but when the fan is working, external dust, oil and harmful gases will also enter the control cabinet and be electrostatically adsorbed on the surface of the circuit board. Over time, it will cause SMD components. And the corrosion of the printed circuit, at the same time affect the heat dissipation of the components. The accumulated dust will also cause a short circuit in the high-voltage part of the circuit board when it is damp. The longer the control cabinet works, the more prominent the above-mentioned problems will be, and when it accumulates to a certain extent, it will cause a sudden failure of the control part.
The cabinet air conditioner achieves heat absorption and cooling through compression refrigeration, so that when the control cabinet is airtight, the heat and moisture in the air in the control cabinet are transferred to the outside of the cabinet. High temperature, dust, oil, and corrosive gases in the external environment will not enter the inside of the control cabinet, thus solving a series of problems caused by fan heat dissipation. The control cabinet can always be maintained in an ideal temperature environment of 30-35℃, and the service life and stability of electronic and electrical equipment are effectively guaranteed.
