Outdoor advertising machines are very common in our lives now. We can see outdoor advertising machines in many public places. However, in the hot summer, the heat and high temperature is a "fatal injury" for electronic equipment. Let's take a look at how the outdoor advertising machine cools down by itself.
One, air-cooled heat dissipation
The working principle of air cooling is to exchange the hot air inside the outdoor advertising machine with the cold air outside to achieve the purpose of cooling down.
2. Air conditioner cooling
Air-conditioning heat dissipation refers to the use of air-conditioning to dissipate heat inside the equipment, and the inside is divided into outer circulation and inner circulation. The outer circulation means that the air conditioner is in contact with the outside air, while the internal components are in the inner circulation and not in contact with the outside, which ensures the sealing, heat preservation and dust resistance, and makes the effect better. The use environment of the air conditioner can be completely isolated from the outside world, and the air conditioner itself is dust-proof and moisture-proof, so its protection level can be IP65.
Three, heat exchanger heat dissipation
The principle of heat dissipation of the heat exchanger is to reduce the internal temperature by adding aluminum platinum fins to the high heat conduction efficiency of the fan, so its cooling effect will be worse than that of real ventilation. But its advantage is that it can be absolutely dustproof and waterproof steam (without the function of dehumidification) and convenient transportation. So it can be suitable for some places with low temperature all year round.
The above content is about some knowledge about outdoor advertising machine cooling, I hope it can help everyone.
