Frequency converter power module

Abstract

The invention discloses a frequency converter power module, which comprises cooling fans, first water-cooled cooling plates, a second water-cooled cooling plate, a cabinet body, intelligent power modules (IPMs), electrolytic capacitors, busbars, thyristors, fuse protectors, a transformer, wire inlet end copper bars and wire outlet end copper bars, wherein the IPMs and the electrolytic capacitors are correspondingly connected with the busbars respectively; the thyristors are connected with the electrolytic capacitors; the fuse protectors and the transformers are correspondingly connected to the thyristors respectively; the wire inlet end copper bars are connected with the fuse protectors; the wire outlet end copper bars are connected with the IPMs; multiple groups of cooling fans are arranged at the top end of the cabinet body; three first water-cooled cooling plates and one second water-cooled cooling plate are arranged on the rear outer side surface of the cabinet body; the first water-cooled cooling plates are located at the positions of the IMPs; and the second water-cooled cooling plate is located at the positions of the thyristors. According to the frequency converter power module disclosed by the invention, a medium for heat conduction is transformed into liquid water from a gas, so that the cooling effect is relatively good.

Description

Technical field: [0001] The invention relates to a frequency converter power module, which belongs to the technical field of blowers. Background technique: [0002] The heat dissipation and cooling of traditional inverter power modules generally use air as the heat transfer medium. This method has the following problems: [0003] 1. It needs to be equipped with a high-power cooling fan; [0004] 2. The heat dissipation efficiency is not high, the energy consumption is large, and the cost is high; [0005] 3. Considering that the air flow needs to meet the cooling requirements, the volume of the air duct is large; [0006] 4. High sealing requirements, high processing and assembly costs. [0007] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0008] The present invention provides a frequency converter power module in order to solve the above-mentioned problems in the prior art. [0009] The technical...
