This utility model discloses an intelligent zoned heat dissipation system for frequency converters, including a chassis, a low-temperature zone module, a medium-temperature zone module, a high-temperature zone module, a temperature sensor network module, and an intelligent control unit module. An isolation structure is provided between the medium-temperature zone module and the low-temperature zone module. The medium-temperature zone module is equipped with a second air intake channel that directly introduces ambient cooling air from outside the chassis and a main cooling fan. Temperature sensors monitor the temperature of each zone, and the intelligent control unit dynamically adjusts the speed of the main cooling fan based on the temperature data. This utility model effectively isolates thermal crosstalk between temperature zones by providing an independent, high-quality cold source for the core heat-generating areas and achieves intelligent on-demand heat dissipation, thereby improving heat dissipation efficiency, reducing energy consumption and noise, and enhancing the reliability and lifespan of the frequency converter. It is mainly applied to the heat dissipation of power electronic equipment such as frequency converters and inverters.

The utility model relates to a flat flame burner, relates to burner field, including base, and lower casing and upper casing mutually assembled on the base, be located the fixed station between lower casing and base, the inner side of upper casing is equipped with protective gas ring, spacing ring and sintering pan in proper order, the sintering pan is equipped with nine burning hole, the burning hole is equipped with the lower casing, the upper casing is equipped with the fixed station between lower casing and base. A fuel pipe is inserted into each hole and extends to the position below the base. The flat flame burner is improved on the basis of an existing single-hole flat flame burner, nine holes are formed in the sintering disc, and each hole is provided with a fuel pipe, so that the flat flame burner is suitable for researching the porous combustion characteristic of the flat flame burner; comprise porous combustion phenomenon characteristics, whether crosstalk exists during combustion of a plurality of holes, whether flames are enhanced or weakened during combustion of the holes, and whether an arrangement mode has influences on the flames.
