2). LCD advertising machine industrial air conditioning heat dissipation type (ACU)
Principle: Use air-conditioning compressor to work, send cold air into the box, and radiate the electronic parts. The protection level is IP65, and the applicable working temperature is -40~+55℃. It is used in places with large temperature difference and harsh environment (big dust and humidity).
Advantages: LCD advertising machine IP65 protection, good environmental adaptability.
Limitations: LCD advertising machine has high power consumption, high operating cost and thick product as a whole.
3). Heat exchanger type (HEU)
Principle: LCD advertising machine uses external low-temperature air and internal high-temperature air to exchange heat on the thin metal surface of heat exchange core to reduce the internal temperature. The protection level is IP65, and the applicable temperature is -20~+40℃.
Advantages: IP56 protection, power consumption between air cooling and air conditioning.
Limitations: LCD advertising machine is suitable for narrow ambient temperature and thick products.
4. Low temperature solution for LCD advertising machine: heating and insulation design.
In cold regions (such as Northeast China and Russia), Ruiguan adopts intelligent PID temperature control algorithm to dynamically adjust the heating power according to the temperature difference between inside and outside to ensure the normal operation of LCD screen (temperature -20℃) and electronic components. At the same time, the energy consumption is reduced through the aerogel insulation layer of LCD advertising machine, and the heating efficiency is improved by 25% compared with the traditional scheme.
5. Technical differentiation of LCD advertising machine of Ruiguan.
Design of LCD advertising machine simulation driver: based on ANSYS Fluent thermal simulation modeling, the feasibility of the scheme is verified in advance, and the development cycle is shortened by 30%.
Modular structure of LCD advertising machine: support rapid adaptation of various heat dissipation schemes such as fans, air conditioners and heat exchangers.
Life cycle management: Built-in temperature control sensor and remote operation and maintenance platform can monitor the equipment status in real time and warn potential risks.
The competition of outdoor digital signage of LCD advertising machine will eventually return to the core value of "high reliability, excellent display effect and long-term stability". Xunbao provides global customers with full-size outdoor digital signage products ranging from 18.5 inches to 110 inches, covering outdoor advertising machines, outdoor televisions, mobile water signs and other forms by virtue of its full environmental adaptability of -45℃~55℃, 5000nit ultra-high brightness display and modular heat dissipation scheme.
