In the sun, not only outdoor LED display to do the heat, in fact, there is no air conditioning indoor, indoor LED display how to heat, but also must consider a problem, today from the technology to talk about their own experience!
Follow the show career development, small, ultra-thin, easy to become the primary direction of career development. And follow the miniaturization of equipment and frivolous, there is no large volume of cooling fan and water cooling structure, how to complete the effective operation of the floating machine? And thus reduce the damage to high heat and its parts and components.
For the indoor screen, because there is no threat of sunshine, as if to cut some of the elements of harm. However, the corresponding, the indoor demand for goods frivolous higher, the surrounding goods available free convection space is limited. These elements make the indoor equipment cooling is not simple.
Now the display device cooling is divided into metal heat sink, heat pipe, fan, water and other methods. During which the first two attributed to forced cooling. The latter two are attributed to automatic heat dissipation. The so-called automatic cooling, forced to heat, mainly because there is no need to supply additional power, to fulfill the cooling as a definition.
Heat sink is the most typical forced cooling components, in addition to heat pipe (heat pipe) is also increasingly popular in recent years, forced cooling components, in the field of heat, high thermal conductivity is still the main direction of skills to carry out, Good thermal conductivity, light weight, easy processing of metals such as aluminum or copper, heat conduction better silver is too expensive, generally not selected. In the daily use of us, but also help with thermal paste, such as our more common within the computer "silicone".
Heat pipe is another more common way to see the thermal solution, light, can be quickly homogeneous characteristics, it has excellent thermal conductivity characteristics, the use of heat pipe size is appropriate, the most early use in aerospace Industry, now all over the use of all kinds of heat exchangers, coolers and other different applications, play heat transfer and cooling characters.
The most common automatic cooling, is the use of motor fan fan cooling fan, in addition to the most seen computer case, the power supply on the installation, and heat sink, heat pipe combined into a combination of heat dissipation device , Is widely used in the presentation card, the central processor and other primary computer processor.
Water cooling is the use of liquid in the pump under the stock force forced to take away the heat sink heat, compared with the air-cooled with a quiet, stable temperature, the environment depends on small and so on. The cooling function of the water-cooled radiator is proportional to the flow rate of the radiating liquid (water or other liquid), and the flow rate of the cooling liquid is related to the pump power of the cooling system. And the heat capacity of the water is large, which makes the water-cooled refrigeration system has an excellent thermal load. Suitable for air-cooled system 5 times, resulting in the direct advantage that is related to the component operating temperature curve is very steep. For example, the use of air-cooled radiator system in the operation of the CPU load when the program will show a short time in the temperature hot spikes, or may exceed the CPU alert temperature, and water cooling system because the heat capacity, heat shake relatively small Much more.
