Outdoor power case

Abstract

The invention relates to an outdoor power case, which comprises a power case shell body consisting of an upper cover and a middle framework; the inside of the power case shell body is provided with an IGBT module, a radiator, a reactor and an inductor; the IGBT module is fixed on the middle part of the radiator; the reactor and the inductor are fixed on the radiator close to an air outlet of the middle framework; the air outlet of the middle framework is provided with a shutter structure; left and right sides of the upper cover cover the air outlet; a gap is reserved between the upper cover and the middle framework; and sealing strips are arranged on the rims of the middle framework. The outdoor power case can effectively dissipate heat, and is reliably waterproof; and the arrangement of devices in the case is reasonable.

Description

technical field [0001] The invention relates to a structural arrangement of a power box shell and internal components. Background technique [0002] In order to establish a conservation-oriented society, the country is vigorously developing photovoltaic / grid-connected power generation technology, and outdoor power boxes play an important role in the application of this technology. However, the biggest problem with outdoor power supplies at present is to ensure the heat dissipation of the box, and at the same time prevent rainwater from penetrating into the box and causing damage to the components in the box. The current outdoor power supply box is provided with a heat dissipation channel on the side or front of the box body to ensure heat dissipation, so it is difficult to ensure that rainwater will not infiltrate into the box body from the heat dissipation channel. In addition, the unreasonable discharge of the components in the box causes the heat dissipation of the compo...

AI Technical Summary

Problems solved by technology

However, the biggest problem with outdoor power supplies at present is to ensure the heat dissipation of the box and at the same time prevent rainwater from penetrating into the box and causing damage to the components in the box.

In the current outdoor power box, heat dissipation channels are set up on the side or front of the box to ensure heat dissipation, so it is difficult to ensure that rainwater will not seep into the box from the heat dissipation channel

In addition, the unreasonable discharge of components in the box causes the heat dissipation of the components in the box to interfere with each other, and the heat emitted by the components in the box cannot be removed in a timely and effective manner.
