The heat dissipation technology of industrial LCD screen: How to maintain low temperature operation?
In today's electronic equipment, the industrial LCD screen has become a mainstream display technology. Because it has the advantages of low power consumption, lightness, and broad perspective, it is widely used in various devices, such as mobile phones, tablets, televisions, and displays. However, as the resolution and refresh rate increase, and the increase in the driving voltage of the LCD panel, the heating problem of LCD is becoming increasingly serious. Therefore, in order to ensure that LCD can maintain low temperature operation, various heat dissipation techniques have been developed.
1.Cooling design
LCD's cooling design is carried out in its structural design. Generally speaking, the cooling design of LCD mainly includes the design of the heat dissipation structure and the choice of thermal conductive materials. Good heat dissipation structure design can effectively transmit heat from the inside of LCD to the outside, while thermal conductive materials can effectively pass the heat from one material to another one.
2.Cooling fan
LCD's cooling fan is a common cooling method. The heat dissipation fan can be installed inside the LCD and takes away the heat through the air convection. In addition, some high -end LCD screens also use multi -fan design to enhance the heat dissipation effect.
3.Thermal pipe technology
The heat pipe is an efficient heat transfer element that can pass the heat by evaporating and condensation. In the LCD, the heat pipe can transmit heat from the heating site to other parts, thereby enhancing the heat dissipation effect. In addition, the heat pipe can also use the design of multiple copper pipes or aluminum pipes to further improve the cooling efficiency.
4.Liquid cooling technology
Liquid cooling technology is an efficient cooling method. In the LCD, the liquid cooling system can flow the cooling fluid through the various parts of the screen through the pipeline, there by taking away the heat. Liquid cooling technology has the advantages of high heat dissipation efficiency and small noise, but requires higher design and manufacturing technology.
5.Phase transition material
The phase -changing material is a material that can absorb and release heat. In the LCD, phase -changing materials can be placed on the back or side of the screen. When the screen is hot, the phase transformer material can be absorbed and stored in heat. When the screen is cooled, the phase change material can release the heat, thereby keeping the low temperature operation of the screen.
In summary, LCD's cooling technology is diverse, and each technology has its unique advantages and applicable scenarios. When choosing the cooling technology of LCD, you need to choose according to the specific needs and actual situation of the product. At the same time, with the continuous development of technology, I believe that more efficient LCD heat dissipation technology will appear in the future.
