Higher power electronic components allow automotive system designers to meet higher mandatory automotive fuel efficiency standards while meeting stringent overall emissions requirements. To meet these standards, power MOSFETs with a current capability of more than 200 amps and an on-resistance of less than 1 milliohm must be used to reduce transmission losses and improve overall efficiency. To date, the automotive market has not yet introduced MOSFETs that meet these requirements.
In addition, the H-PSOF package is smaller in size and height than the standard D2PAK package (TO-263) commonly used in automotive applications of the same type. The area of â€‹â€‹the H-PSOF package is about 20% smaller than the current D2PAK, and the height is almost half that of the D2PAK.
YLW series of coal/biomass fired thermal oil boilers use coal or biomass as the fuel and thermal oil as the medium, and force the medium to conduct liquid phase circulation by the circulating oil pump. The boiler consists of the body above and the grate below.
The radiation heat transfer section of the boiler body adopts the double square shaped compact coil structure, the convection heat transfer section adopts the S shape multiple passes heat transfer. A high efficiency air preheater is equipped at the tail of the boiler, it can absorb heat and reduce exhaust gas temperature. After the fuel is fully burned in the combustion chamber, most of the heat is absorbed by the radiation heating-surface, the high temperature flue gas enters the convection heating surface and transfer the heat. After it comes out of the boiler, the air that is needed by boiler combustion is heated in the air preheater.
Then it passes the dust collector and is drawn by the I.D. fan to be discharged into the atmosphere through the chimney.
