Outdoor vertical touch advertising machines are often affected by the weather, and the internal structure is more complicated than ordinary advertising machines, especially in terms of heat dissipation of the machine. The vertical touch advertising machine should do a good job of heat dissipation, so as to reduce the damage of the temperature to the machine and protect the service life of the machine. Let's take a look at the heat dissipation method and principle of the outdoor vertical touch advertising machine!
1. The principle of air cooling and heat dissipation is that the hot air inside the outdoor vertical touch advertising machine is replaced with the outside air, exchanged and then cooled, and the speed control board of the key components of cooling is the most important.
2. The operating principle of the heat exchanger is to pass the fan and add the high thermal conductivity of aluminum and platinum sheets, and then reduce the internal temperature, so its cooling effect will be worse than that of true ventilation, and the internal temperature should be the same as the external temperature. A temperature difference of 15-20 degree can be used for heat exchange, but its advantage is that it can be dustproof and waterproof (without dehumidification).
3. The principle of air-conditioning heat dissipation is that there is an environmentally friendly R134a refrigerant in the compressor, and the gasification and liquefaction of the refrigerant is used to bring the internal heat of the outdoor advertising machine to the outside. When the internal temperature of the outdoor vertical touch advertising machine reaches 35 degree , It can start the refrigeration function independently, and the compressor stops working when the temperature drops to 30 degree . The operating environment of the air conditioner can be completely isolated from the outside world, and its protection level is higher than that of air cooling. The air cooling can only achieve IP55 while the air conditioner can achieve IP65.
The above is just an introduction to the heat dissipation of the outdoor vertical touch advertising machine. When you choose a vertical touch advertising machine, you must pay special attention to the heat dissipation. Only the heat dissipation of the machine will not affect the normal use of the machine. At the same time, everyone must choose a regular brand. The quality of the regular brand vertical touch advertising machine is guaranteed to a certain extent, and there will be no frequent problems.
