Abstract
The invention discloses a frequency converter having dual dustproof and waterproof functions. The frequency converter comprises a frequency converter main body, a control panel, a sealing cover, a heat suction pipe, a locking device, a clamping groove, a heat dissipation shell, cooling holes, an inner shell, an outer shell, a ventilation passage, a first sealing cushion, an installation seat, a rear cover, a filtering net, a cooling fin, a cooling structure, an internal fan, a partition plate, a second sealing cushion, an air inlet passage, an external fan, a dustproof net, an external connection cable, a plug, a socket, an internal cable, a sealing ring, an air blowing pipe and a drying box. The frequency converter is reasonable and simple in structure, the frequency converter main body is arranged in the waterproof sealing shell, the influence of external water and dust can be effectively prevented, the internal fan can be used for effectively allowing air in the inner shell to flow,the flowing air can pass through an internal cooling groove in the cooling structure for cooling, meanwhile, the external fan also can be used for blowing heat in the cooling structure to the coolingshell via external cooling holes, and the heat is dissipated through the cooling holes.
Description
technical field [0001] The invention relates to the technical field of frequency converters, in particular to a frequency converter with dual functions of dustproof and waterproof. Background technique [0002] Inverter is one of the indispensable important devices for modern motor speed control and energy saving, and it is widely used in the industrial field. The main circuit of the inverter is composed of rectifier circuit, intermediate circuit and inverter circuit. During the working process, the power devices in these circuits generate a lot of heat, so the casing of the inverter is generally equipped with ventilation and cooling holes. At the same time, the inverter is generally installed near the working site close to the motor. If it is working on a rainy day, the water vapor in the air will easily enter the inverter housing with the cooling wind, and the dust in the working site will easily enter the inverter housing with the cooling air. and dust cause damage to th...
