At present, the types of heat-dissipating mechanisms of high-power LEDs can be roughly classified into two types: "active heat dissipation" and "passive heat dissipation". Active heat dissipation can be divided into additional fan forced cooling and water-cooling heat dissipation. In addition, passive heat dissipation can be divided into : Natural heat dissipation, heat pipe and fins, temperature plate and fins, loop heat pipe technology, etc.
If the heat transfer method can be divided into three ways: "heat conduction", "heat convection" and "heat radiation". Heat conduction refers to the phenomenon that heat flows from a high temperature to a low temperature in a solid medium. The high temperature object is placed in the air, in the cooling water or cooled by the fan, which belongs to the transfer of heat convection. Lower fluid temperatures, higher fluid flow rates, and larger contact areas all contribute to the effect of heat convection. Basically, increasing the heat dissipation area, using materials with better heat conduction, and matching fans are common methods for solving the heat dissipation problem of LEDs.
The LED bulb is designed to match the flow direction of the fan airflow through the opening, so that the waste heat generated by the LED can be quickly carried from the inside of the bulb to the outside of the bulb. (Click on the image to view the original image)
A tablet computer is an electronic device that integrates mobile commerce, mobile communication and mobile entertainment, with a touch recognition LCD screen, handwriting recognition and wireless network communication functions. At present, the tablet computer has become the most popular electronic product.
1.In appearance, the tablet computer looks like a large-screen mobile phone, or more like a separate LCD screen.
2.In terms of hardware configuration, a tablet computer has all the hardware devices of a traditional computer, and has its own unique operating system, compatible with a variety of applications, and has a complete set of computer functions.
3.Tablet PC is a kind of miniaturized computer. Compared with traditional desktop computers, tablet computers are mobile and flexible. Compared with notebook computers, tablet computers are more compact and more portable.
4.Tablet PC is a digital notebook with digital ink function. In daily use, you can use the tablet computer like an ordinary notebook, take notes anytime and anywhere, and leave your own notes in electronic texts and documents.
