This article to talk about wireless charging semiconductor radiator disassembly, as well as the corresponding knowledge points of wireless charging heat dissipation, I hope to help you, don't forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, Semiconductor radiator principle
The principle is that the fan is started after the power is powered on, and the air duct on both sides is drained and supported, so that the entire fuselage can achieve air circulation to cool the internal cooling chip, which is affixed to the back of the mobile phoneMinistry way to gradually cool down. But the shortage is that a lot of heat behind the refrigeration chip itself needs to be discharged through the back fan, the exhaust outlet is just opposite my hands, the fuselage is too wide and inconvenient to use, and it can reach 2 degrees Celsius. It's also a very good phone radiator.
On the specific principle, the heat dissipation principle of graphite heat dissipation is actually the use of graphite has a unique grain orientation, it evenly heat conduction in two directions, while ductility and strong, can be attached to the circuit board inside the mobile phone, which can block the contact between components, but also play a certain role in earthquake resistance.
Base of semiconductor heat sinkThe principle is to force the heat transfer through the semiconductor to the hot end (fin), and then through the fan to take away the heat of the fin, essentially through the fan fin to complete the heat dissipation, the threshold of heat dissipation capacity is also the heat dissipation capacity of the fan fin, and the semiconductor radiator basically 90% of the power consumption is consumed in the operation of the semiconductor thermal conductivity material.
Heat dissipation principle After the semiconductor heat sink is powered on, the temperature at one end will decrease, and the temperature at the other end will increase, that is, the heat transfer inside the heat sink (that is, the thermoelectric effect, also known as the Peltier effect). Because the heat sink is working without refrigerant, and there isThe South Core SC9711 and the WIZ MOS tube play an important role in the DC-DC conversion. Together with the South Core SC3503 synchronous rectifier controller and the AOS32922 synchronous rectifier MOS tube, they achieve high performance voltage regulation. The precision design of the output filter capacitor and inductor, as well as the addition of the secondary buck IC SC9711 (made by the South core, supporting 100W power), further optimizes the output performance.
SP6518F also has a built-in high pressure direct detection technology, which can withstand up to 200V; And the self-powered technology greatly expands the application range of output voltage; Under low pressureIn high-current switching power supply applications, it easily meets level 6 energy efficiency and is a good solution for ultra-low on-voltage drop rectifier devices.
The output VBUS switch tube is packaged with VZ VS3610AE, NMOS, 30V, PDFN3333. Vvs3610ae data information.
Detailed specifications of the VS3618BE. Close-up of the USB-C port after removing the dust cover. Redmi 67W fast charger all disassembled. Charging head network disassembly summary as a game mobile phone standardThe Redmi 67W fast charger has changed the standard color scheme of traditional accessories, which is either black or white, but chose to use the yellow body and black end cover plate, and the bright color scheme makes this charger look more in line with the aesthetic style of young people.
1, Millet 55W vertical air-cooled wireless charging using PC flame retardant material plastic shell, fuselage edge clear end Angle arcThe support plate is black and the base is sandblasted in gold. From the front, the front end of the base is equipped with LED indicators, and the support board is layered above and below, using different designs. Indicator light is green when working.
2, Millet 55W vertical air-cooled wireless charger is equipped with a special bracket, can be directly installed on the base, and is embedded, especially stable! It can be removed at any time when not in use, because it is specially configured for the Mi 10 Ultra, and it is generally not used.
3, Mi 9 Pro supports 55W vertical air-cooled wireless fast charging, but there will be no wind in the process of chargingFan rotation. This is normal, because during fast charging, the phone will emit some heat, but it is not too high, so it does not need a fan to turn to dissipate heat.
The introduction of wireless charging semiconductor radiator disassembly let's talk about it here, thank you for taking the time to read the content of this site, more information about wireless charging heat dissipation, wireless charging semiconductor radiator disassembly don't forget to find oh in this site.
