Embodiment Construction
[0022] In order to overcome defects such as corrosion of electronic devices caused by a large amount of dust brought by the air-cooled mode of the frequency converter in the prior art, withstand voltage reduction, condensation, breakdown and sparking, the present invention provides an electronic device that can Inverter structure in which the circuit board and cooling air duct are separated. In the present invention, the outer casing is divided into two independent spaces, thereby separating the circuit board, the capacitor device and the second cooling air duct of the frequency converter. At the same time, a heat dissipation assembly is arranged in the space for accommodating the circuit board and the capacitor device, and the capacitor device is accommodated in the heat dissipation assembly, so that the heat dissipation assembly is connected with the air inlet and the air outlet respectively, thereby forming the first heat dissipation inside the heat dissipation assembly. Th...

The invention discloses a converter. The converter comprises a housing body with an accommodation space, a partition wall arranged in the accommodation space, a circuit board and a plurality of capacitors contained in the accommodation space, and a radiating component contained in a first containing chamber, wherein the partition wall partitions the accommodation space of the housing body into the first containing chamber used for containing the circuit board and a plurality of capacitors; the plurality of capacitors are accommodated inside the radiating component, and the circuit board is positioned at the outer part of the radiating component; a first air inlet and a first air outlet are arranged on the housing body, and the first air inlet is arranged on the position of the housing body corresponding to the first containing chamber; one end of the radiating component is communicated with the first air inlet, the other end of the radiating component is communicated with the outside through the first air outlet, a first radiating air channel is formed along a first air inlet path and a first air outlet path of air stream in the radiating component, and the first radiating air channel and the circuit board are separated by the radiating component.
Description
technical field [0001] The invention relates to a frequency converter, in particular to a frequency converter with good heat dissipation and sealing functions. Background technique [0002] The frequency converter is a commonly used power supply device in the prior art. There are a large number of power devices in the frequency converter, such as bus capacitors, rectifier bridges, filters and so on. When designing the structure of the frequency converter, it is necessary to comprehensively consider the influence of each device, the ventilation and heat dissipation performance of the system, the reasonable compactness of the structure, and installation and maintenance based on the performance of each power device itself, so as to obtain the energy index. The best frequency converter. [0003] However, the electronic components of various frequency converters in the prior art usually include a capacitor device with the largest heat generation and a circuit board with a relat...
