Base of converter and converter

Abstract

The invention relates to a base of a converter and the converter. The converter comprises a front cover, a middle shell, a control part, a main PCBA and the base, wherein the base comprises an upper plate, a lower plate, an upright plate and two side plates; the upright plate is connected with the upper plate and the lower plate and isolates the base into a first cavity and a second cavity; the two side plates are arranged vertical to the upright plate; one side plate is provided with a fan fixing frame and an air outlet and the other side plate is provided with an air inlet; and the first cavity, the air inlet and the air outlet form an independent air duct. Vertical layout is adopted by the base and a product can be compressed in width, so that the utilization rate of main PCBA layout isimproved, the width and the volume of the overall product are reduced, the structure is simple and assembly is easy; components with a large calorific value are arranged in the independent air duct,components with a small calorific value are arranged in the second cavity, and heat dissipation is sufficient under the isolation action of the upright plate, so that the reliability of the product isimproved and the converter is suitable for application in a relatively harsh operating environment.

Description

technical field [0001] The invention relates to the technical field of frequency converters, in particular to a base of frequency converters and frequency converters. Background technique [0002] At present, the overall structure of the frequency converter on the market is usually a flat structure, which is basically a stacked structure composed of a base, a middle case, a main PCBA board, a control part and a front cover from bottom to top. The width is not easy to compress, the space utilization rate of the main PCBA is low, and the structure is relatively complicated, so it is difficult to realize the miniaturization of the volume. There are also some products on the market that adopt a book-like design, but adopt a horizontal tiled design. The product structure is complicated, there are too many plastic parts to disassemble, the cost is high, and the disassembly process is also complicated, which needs to be improved.
