Problems solved by technology

However, this method of arranging electrolytic capacitors in the radiator air duct to achieve heat dissipation takes up a lot of space in the radiator air duct, hinders the air flow, and cannot meet the temperature rise requirements inside the inverter
In order to meet the temperature rise requirements, the internal space of the inverter is currently increased to promote heat dissipation, but this method increases the volume of the inverter, increases the cost, and has certain restrictions on the use of the inverter space, which is not conducive to the inverter Promoted application of

Abstract

The invention provides a frequency converter comprising a first box body, a second box body covering the first box body, and a driving plate arranged between a first top plate arranged at the first box body and a second base plate arranged at the second box body. A plurality of first electrolytic capacitors are arranged at one side, approaching the second box body, of the driving plate; and a second ventilation hole is formed at the place adjacent to the first electrolytic capacitors. First through holes where the first electrolytic capacitors pass and a first ventilation hole corresponding to the second ventilation hole are formed in the second base plate. A first air flue port and an air outlet communicated with the first air flue port are formed in the first box body; and the first air flue port protrudes from the first top plate and penetrates the second ventilation hole and the first ventilation hole. External air flows through the first electrolytic capacitors and then flows out of the air outlet through the first air flue port. According to the invention, an independent heat radiation air flue is provided for the first electrolytic capacitors arranged on the driving plate, so that a problem of heat radiation of the first electrolytic capacitors can be solved. Moreover, the frequency converter has advantages of small size and low cost.

Description

Technical field [0001] The invention relates to the technical field of frequency converters, in particular to a frequency converter that meets the heat dissipation requirements of electrolytic capacitors. Background technique [0002] The inverter is equipped with a fan and a driving board. The electrolytic capacitor installed on one side of the driving board is located in the air duct of the radiator. The rotation of the fan encourages external air to flow in from the air inlet at the bottom of the inverter and flow out from the air outlet through the air duct of the radiator. , In order to realize the heat dissipation of the electrolytic capacitor and the forced air cooling inside the inverter. However, this method of arranging electrolytic capacitors in the air duct of the radiator to achieve heat dissipation occupies a large amount of space in the air duct of the radiator, hinders air flow, and cannot meet the temperature rise requirements inside the inverter. In order to me...
