  •      Outdoor advertising machines, irrelevant weather, can display your information outdoors, bringing good visual and auditory enjoyment to outdoor information dissemination. Can be widely used in outdoor advertising, outdoor public information release, outdoor media communication, touch interactive query and other fields.
  •  
  •      The advertising machine is a new generation of intelligent devices, which constitute a complete advertising broadcast control system through terminal software control, network information transmission and multimedia terminal display, and through multimedia materials such as pictures, texts, videos, small plug-ins (weather, exchange rates, etc.). Advertising.

  •      Then, the following KONWHAI advertising machine manufacturers Xiaobian introduce you to the difference between outdoor advertising machines and ordinary advertising machines?

  • Advertising machine outdoor and ordinary difference

  •   The difference between outdoor advertising machines and ordinary LCD advertising machines:  
  •  
  • 1. The difference in the structure of the fuselage:
  •  
  •      There is no difference in function between the outdoor advertising machine and the ordinary LCD advertising machine, but there is a big difference in the structure. The outdoor advertising machine as the name suggests is used outdoors, and the internal structure of the outdoor advertising machine requires high complexity due to the weather and climate. An advertising machine used in ordinary indoors.
  •  
  • 2. The difference in heat dissipation of the fuselage:
  •  
  •      Outdoor advertising machines are used for outdoor lighting. The high-brightness LCD screen generates heat, and the sun is shining. It is easy to cause a black screen on the screen. Therefore, the heat dissipation of the high-bright screen becomes a top priority. The heat dissipation is reflected in the air volume of the outdoor advertising machine fan, the calculation of the wind pressure and the reasonable circulation air duct.
  •  
  •      According to the cooling outdoor advertising machine, there are three ways of air cooling, air conditioning cooling, and heat dissipation of the heat exchanger.
  •  
  •      The principle of air-cooling and heat dissipation is that the hot air inside the advertising machine alternates with the outside wind, and the temperature is reduced to achieve the cooling. The speed-adjusting board of the key components for cooling is the most important. Meishimei Electronic Technology-Kangweihai independently develops a new type of fan Speed ​​plate, its appearance can make outdoor advertising machine heat dissipation more reasonable, more energy-saving and environmentally friendly.
  •  
  •      The principle of air-conditioning heat dissipation is that the refrigerant in the compressor has environmental protection R134a. The internal heat of the advertising machine is brought to the outside by the gasification and liquefaction of the refrigerant. When the internal temperature of the advertising machine reaches 35 °C, the refrigeration function can be started automatically. The compressor is stopped when it drops to 30 °C. The air conditioning environment can be completely isolated from the outside world, and its protection level is higher than air cooling. Air cooling can only achieve IP55 and air conditioning can achieve IP65.
  •  
  •      The principle of use of the heat exchanger is the high heat transfer efficiency of the camel fan plus the aluminum platinum sheet, so that the internal temperature is lowered, so its cooling effect is worse than the true ventilation, and the internal temperature is once compared with the external temperature. The temperature difference of -20 °C can be used for heat exchange, but its advantage is that it can be absolutely dustproof and waterproof (no dehumidification function).
  •  
  •      Since the ordinary liquid crystal advertising machine is fixed indoors due to the use environment, the brightness of the liquid crystal screen does not need to be brightened, and the heat generation is small, so that no additional heat dissipation of the body is required. The outdoor LCD advertising machine and the ordinary LCD advertising machine have different use environments, and the fuselage structure is different, so the user can decide which LCD advertising machine to purchase according to his actual needs.
