China Drying Network News National high-tech enterprise Zhejiang Fengli Crushing Equipment Co., Ltd. Absorbed and digested foreign micro-pulverization advanced technology re-innovation, successfully developed a new generation of airflow micropowder equipment - air flow turbine micropowder, recently obtained national utility model patent (Patent No. .7). The patent has the advantages of high crushing efficiency, free adjustment of product particle size, ideal grading effect, uniform and adjustable feeding amount, good heat dissipation performance, simple operation, and convenient cleaning. Suitable for processing a variety of materials, heat-sensitive and fibrous materials can be competent, uniform product size, can be crushed to micron and sub-micron size, is the current performance of good, high efficiency and energy-saving ideal micro-powder production equipment. This is another honor for the product after it has obtained national key new products and is included in the National Torch Plan project.
With the in-depth development of China's material industry, ultrafine grinding has become one of the most important deep processing technologies for mineral raw materials. The use of powder materials after deep processing by this technology has become increasingly widespread, and the grade and added value of the products can be improved. The benefits are significant. However, there are crushing machines in the country with varying degrees of smashing, large particle size, and uneven particle size, especially for fibrous, heat-sensitive organic materials that are difficult to crush, and so on. Therefore, such devices have been imported from the United States and Japan for a long period of time. Need to spend a lot of foreign exchange.
In order to change the status quo of micro-pulverizers that integrate the dual functions of smashing and air-flow classification in the country, and meet the market demand for high-grade ultrafine pulverization equipment, Zhejiang Fengli has successfully developed air-flow vortex under the guidance of relevant scientific research institutes. Powder machine. The aircraft structure is advanced and consists of two parts: the upper part and the lower part. The lower part is the inlet chamber; the upper part is divided into a crushing chamber and a classification chamber by a diverter ring. The crushing chamber is composed of a shredder disc and a toothed bushing to crush the material into fine powder; the classifying chamber is composed of a stepped impeller and can The material is divided into qualified fine powder and unqualified fine powder. The qualified fine powder is discharged through the discharge outlet and collected by the cyclone collector. Unqualified fine powder falls back along the inner wall of the diverter ring to the crushing chamber and continues to be crushed.
This machine performance is different:
(1) This is a vertical axis reflection mill. The grading device replaces the usually smashed screen and the smashing efficiency is high.
(2) It is equipped with air flow regulating valve and graded impeller stepless governor, which can adjust the product granularity without stopping the machine, and the fine powder can be completely recovered without polluting the environment.
(3) The machine has a cooling function, low temperature rise during crushing, and is particularly suitable for processing heat-sensitive and fibrous materials, and the finished product has a uniform particle size.
(4) Large production capacity, easy maintenance, operation and cleaning.
(5) The machine adopts a new type of imported narrow V-belt drive, which has the characteristics of large transmission power, stable operation and high efficiency.
At present, the aircraft has been widely used in chemical, pharmaceutical, paint, dyes, feed, plastics, rubber, tobacco, plant fiber, food, pesticides, metallurgy, non-metallic minerals and other industries, ultrafine grinding Mohs hardness of 4 to 5 following A variety of materials, is a high degree of fineness, low noise, high-efficiency energy-saving ideal crusher. The performance of the major indicators of the products has reached the level of similar foreign equipment and can be used as a substitute for imports, and the price is only 10% of imported equipment. Products sell well in the country, exported to Europe and the United States, Southeast Asia, favored by users.
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.
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.
