High-adaptability ventilation filter screen set

Abstract

The invention provides a high-adaptability ventilation filter screen set, and belongs to the technical field of electrical cabinet heat dissipation, the high-adaptability ventilation filter screen set comprises an air filter frame and a panel, the air filter frame comprises a ventilated bottom plate and a connecting plate, and the inner side surface of the connecting plate is provided with a leakage-proof drainage mechanism and an adjusting structure adapted to the size of filter cotton; the adjusting structure comprises two adjusting columns matched with each other, a mounting sliding plate and an adjusting plate; a plurality of grid pieces are transversely arranged in an inner opening of the panel, and waterproof barbs protruding outwards are arranged on the upper end edges of the grid pieces. An edge wrapping frame is arranged on the inner side of the panel along the outer side edge of the panel, and an opening and closing mechanism and a locking mechanism are connected between the edge wrapping frame and the upper end and the lower end of the connecting plate respectively. The ventilation filter screen group provided by the invention has the advantages of being capable of compensating filter cotton production errors, effectively preventing dust and water, preventing large fragments from entering a filter, being convenient to disassemble and assemble, stable in structure and high in universality, and effectively improving the protection performance of a filter device and the operation stability of equipment in an electrical cabinet.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation of electrical cabinets, and in particular relates to a highly adaptable ventilation filter group. Background technique [0002] Since there are a lot of energy-consuming equipment in the electrical cabinet, the heat generated during its operation will affect the stable operation of the equipment and damage the equipment. Therefore, most of the electrical cabinets are equipped with forced convection air cooling devices to reduce the temperature inside the electrical cabinet and improve electrical performance. The operational stability of the equipment. As we all know, there are a lot of dust and impurities in the air, and the airflow generated by the fan can easily drive these impurities into the electrical cabinet, thereby affecting the operation of the equipment in the electrical cabinet, so it is necessary to filter the impurities contained in the air through a filter device .

AI Technical Summary

Problems solved by technology

However, the existing filter devices are too simple in structure, and the filtering effect of the grid panel and the dust filter screen is difficult to eliminate the penetration of water molecules and dust, especially for the installation structure of the filter screen is not tight enough, often occurs when the high-speed airflow passes through. Large protection blind area, low protection and dust removal efficiency, and complicated disassembly and maintenance, resulting in a greatly shortened life and replacement cycle of the filter device, and at the same time cannot adapt to the filter cotton of different sizes caused by production errors, affecting the filtering effect , and then increase the equipment failure rate in the electrical cabinet
