Problems solved by technology

[0002] The frequency converter of a large air conditioner is equipped with a variety of circuit components with high current and high heat generation. If the layout of the circuit components is not reasonable enough, serious mutual interference will occur, thereby greatly reducing the reliability of the frequency converter.
At present, although some inverters on the market have a relatively reasonable circuit layout structure, they have not properly arranged other components in the cabinet cavity. Therefore, considering the comprehensive installation cost, maintenance difficulty and reliability, there are still more big room for improvement

Abstract

The invention discloses a frequency converter. The frequency converter (100) comprises a main cabinet (11), an auxiliary cabinet (12) and a frequency converter cooling system, wherein the main cabinet(11) is arranged on the front side of the frequency converter (100) and is internally provided with a functional module; the auxiliary cabinet (12) is arranged on the rear side of the frequency converter (100) and is spaced from the main cabinet (11) by arranging a main-auxiliary cabinet partition plate (13); the frequency converter cooling system comprises an auxiliary cabinet cooling device arranged in the auxiliary cabinet (12). According to the frequency converter, the main cabinet and the auxiliary cabinet are spaced by means of the main-auxiliary cabinet partition plate, partition arrangement of the functional module and the cooling device of the frequency converter can be realized, the structure inside the cabinet cavity can be simplified, and the reliability is high. In addition,since the main cabinet and the auxiliary cabinet are independent of each other, the frequency converter is convenient to install and maintain, thereby being conductive to saving cost and improving theproduction and maintenance efficiency.
