Morning News On the morning of the 3rd, Chengdu City's 2015 freight car urban road driving license was started at the Chengdu Public Resource Trading Center. An IGBT (Insulated Gate Bipolar Transistor) heat sink is a device used to dissipate heat generated by an IGBT. IGBTs are commonly used in high-power applications such as motor control, power inverters, and welding equipment, where they can generate significant amounts of heat. The Aluminum Heat Sink is designed to provide a large surface area to dissipate the heat, thereby reducing the temperature of the IGBT and preventing damage to the device.The IGBT heat sink is typically made of a material with high thermal conductivity, such as aluminum alloy or copper, and is designed to maximize the surface area available for heat dissipation. The aluminum heat sink is attached to the IGBT using a thermal interface material, such as thermal paste or a thermal pad, which helps to transfer the heat from the IGBT to the heat sink.The design of the IGBT heat sink is critical to its effectiveness. The size and shape of the fins, as well as the spacing between them, can significantly impact the heat dissipation capacity of the heat sink. The aluminum heat sink must also be designed to fit the specific IGBT package and application requirements, as different IGBTs generate different amounts of heat and require different cooling solutions.

Different from previous years, this year's Chengdu City Truck Entry Card has been added to the A3 certificate for new energy trucks with a nuclear load of less than 5 tons (inclusive).
According to the Chengdu Traffic Management Bureau, the number of new energy trucks in Chengdu is currently about 40, which is a new type of environmentally friendly vehicle. In the auction, a total of 41 A3 certificates were auctioned, and the bidding price was 1,300 yuan. The lowest price and the highest price were the same as the reserve price.
In addition, in the A1 card auction used by the freight car that hangs the small car number plate (blue), the A1 certificate with a reserve price of 1,300 yuan has the highest price of 420,000. According to the staff of the Chengdu Auction Center, this unusually high price was caused by the mistake of the auction car owner. In the past, similar situations were not handled.
In summary, an IGBT heat sink is an essential component in high-power applications that use IGBTs. It helps to dissipate the heat generated by the IGBT, thereby preventing damage to the device and ensuring reliable operation. The design of the heat sink is critical to its effectiveness, and it must be carefully matched to the specific IGBT and application requirements.
