Normally, the cabinets we often see are made of sheet metal processing. In the course of use, we need to keep the temperature inside the cabinet within a certain range in order to ensure the long-term stable operation of the network equipment or communication equipment stored inside the cabinet. However, sometimes, due to various reasons, there is a local overheating inside the cabinet, which will have a great impact on the stable operation of the equipment inside. Do you know the causes of local overheating in sheet metal cabinets? Causes and solutions of local overheating of sheet metal cabinets.
1.Causes
With the prolongation of use time, some old equipment inside the sheet metal cabinet cannot be effectively discharged due to the hot air generated by itself, resulting in vortex flow inside the sheet metal cabinet, making the pressure inside the sheet metal cabinet become high, the temperature rises, forming local high heat. In addition, the mismatch between the thermal load and the amount of refrigeration input is also the cause of the rise in temperature within the sheet metal cabinet. In other words, the heat dissipation system inside the cabinet is unable to effectively carry the heat of the internal equipment. Also, the small gap between neighbouring cabinets is a cause of local overheating in sheet metal cabinets, which generally occurs in server rooms.
2.Solution
The traditional solution is to increase the cooling capacity of the entire server room, but this not only consumes more energy, but also has a poor effect on reducing the local overheating of the sheet metal cabinets. There is also a point-to-point active cooling method, through the rack for air conditioning precision air supply, but this method is generally invested more, the deployment cycle is also very long, the actual use is also more difficult. In fact, we can use guided ventilation panels and manual dampers to deflect the cold air so that 90% of it is blown directly to the equipment and it is easy to install without affecting the normal operation of the internal equipment. For the problem of the heat load inside the sheet metal cabinet exceeding the refrigeration capacity, we can start from a safety point of view and equip it with a certain amount of refrigeration margin so that even if there is a failure of heat dissipation in local places, it will not affect the normal operation of the internal equipment.
In summary, these are the causes and solutions for causing local overheating in sheet metal cabinets. Through this method, we can effectively solve the problem of local overheating of sheet metal cabinets, so that, to a certain extent, the normal use of sheet metal cabinets can be better protected.
