Abstract

The invention discloses an inverter device, comprising: a shell, a power module, a heat dissipation structure and an air guide structure; the power module includes a power switch tube; the heat dissipation structure includes a fan and a power switch tube radiator; the power switch tube The radiator has a plurality of heat dissipation teeth; the air guide structure includes a first air guide plate, the first air guide plate is at least partially covered by the power switch tube radiator and adjacent to the heat dissipation of the power switch tube radiator The tooth crest setting. The inverter device of the present invention concentrates the air supply airflow to the heat sink of the power switch tube to dissipate heat through the air guide structure, and can guide the airflow to the tooth root of the heat dissipation tooth, so that the airflow velocity at the tooth root is faster, and due to the The temperature difference between the temperature and the air supply air flow is larger, which can effectively enhance the heat transfer at the root of the tooth, and improve the heat transfer and heat dissipation efficiency.

Description

technical field [0001] The invention relates to the field of inverter technology, in particular to an inverter device. Background technique [0002] An inverter device with an inverter circuit, such as a photovoltaic inverter and an uninterruptible power supply, generally includes a boost circuit and an inverter circuit coupled to each other. Both the boost circuit and the inverter circuit are equipped with power inductors and power switches (such as IGBTs). Most of the heat generated by the inverter device during operation comes from the above two devices, although there are many A heat dissipation structure is used to dissipate heat from the above-mentioned devices, but it is still difficult to solve the defects of low heat dissipation capacity and heat dissipation efficiency of the existing inverter device. Contents of the invention [0003] The purpose of the present invention is to overcome at least one defect or problem existing in the background technology, and pro...
