At present, there are four cooling schemes for outdoor lcd advertising machine display screen system on the market for reference.

1, air cooling heat dissipation

2, air conditioning heat dissipation

3. Heat exchange and heat dissipation

4. Water cooling and heat dissipation

Among them, outdoor lcd advertising machine display screen air-cooled cooling is the most widely used cooling method. Air-cooled heat dissipation is a kind of heat dissipation method developed by using speed regulating fan combined with professional heat dissipation scheme.

Its advantages are low power consumption and low cost. This helps to reduce the cost of later operation. However, the disadvantage is that the protection level is low, which can only reach IP55.

It is necessary to regularly clean the lcd advertising machine display screen filter board and check the running status of the speed regulating fan. It is suitable for most parts of the country, except Northeast China, Northwest China, Hainan, areas with relatively high humidity, coastal cities and heavily polluted areas. The air conditioning cooling scheme is the most widely used cooling method for external use. Its advantages are large heat dissipation, high protection grade (IP65), wide application range, stable performance and long service life.

There are advantages and disadvantages: high power consumption, high construction cost and high operating cost. Applicable to all parts of the country

The outdoor lcd advertising machine display screen heat exchange has the advantages of low power consumption (close to air cooling) and high protection level (IP65).

Disadvantages: lcd advertising machine display screen water cooling system has high cost (higher than air conditioning) and low heat dissipation. It can only be applied to areas with particularly suitable climate.

The water cooling system is not very mature in the whole technology at present, so it is not recommended to use it.

Ruiguan outdoor advertisement Ji special air conditioner

1. Personalized and compact structural design.

2. The unique cold air channel design can efficiently solve the special cooling requirements of various outdoor LCD enclosures and their internal electronic components.

3. The high-efficiency condenser, evaporator and high-reliability compressor are used for ingenious design and layout in a small volume space to obtain large refrigeration capacity.

4. Built-in intelligent control and monitoring technology can effectively ensure that the LCD advertising machine screen of LCD and the electronic components inside the chassis are in the best working temperature range under the external environmental conditions of-40℃ ~+55℃, and ensure the long-term highlight of LCD and the long life of electronic components. In addition, R232 interface provides the monitoring and debugging function of the upper computer.

5. R134A or R410A is used as refrigerant, which conforms to the EU environmental standards and improves the heat exchange effect.

6. The small-caliber copper tube with internal thread (∮7*0.35) and the evaporator and condenser with the third generation hydrophilic membrane fins are adopted to make the refrigeration performance better and the outdoor corrosion resistance stronger. 

Our company has developed various air conditioners with refrigeration capacity of 600 W-3500 W for outdoor lcd advertising machine display screen.
