Inversion device

Abstract

The invention discloses an inversion device. The device comprises: a first shell, wherein a first partition plate is arranged in the first shell in an extending mode along the first end and the second end of the first shell, the first partition plate divides the first shell into a first containing part and a second containing part, and a socket is formed in the first partition plate; a second shell connected with the first shell at the second end; a conversion module comprising a plurality of power devices, wherein at least part of the power devices are arranged in the first accommodating part; a heat dissipation module arranged in the second containing part and used for dissipating heat of the conversion module, wherein the socket is sealed by the heat dissipation module; and an output module is arranged in the second shell and is electrically connected with the conversion module so as to output alternating current. The inversion device is good in heat dissipation effect, and the power device is high in protection performance and not prone to damage.

Description

technical field [0001] The invention relates to the technical field of inverters, in particular to an inverter device. Background technique [0002] Inverter photovoltaics are used in photovoltaics, energy storage and other fields. The inverter contains a large number of power devices, such as power inductors and power switch tubes (such as IGBTs), bus capacitors and filter devices. Most of the heat comes from power devices. Although there are various heat dissipation structures in the prior art to dissipate heat from the above devices, it is still difficult to solve the defects of low heat dissipation capacity and heat dissipation efficiency of existing inverter devices; and the existing After the power device is assembled in the technology, during the wiring or maintenance process, it is easy to make the power device attach water vapor and cause damage to the power device. Contents of the invention [0003] The purpose of the present invention is to overcome the above-m...
