Description

an inverter

Technical field:

The utility model relates to the technical field of DC TO AC inverter power supply equipment such as solar energy/wind energy/storage battery, in particular to an inverter.

Background technique:

The inverter converts DC power (wind energy/solar battery, battery/storage battery) into AC power, which can be grid-connected or off-grid (generally 120V (90-150V), 220V (190V-260V) 50/60HZ sine or square wave). It can also be in the form of emergency power supply, usually by inverting the DC battery into AC. In layman's terms, an inverter is a device that converts direct current (DC) into alternating current (AC). It consists of housing, inverter bridge, control logic and filter circuit. In the past, inverters were not very widely used and were mainly used for resistive loads. There are three types of loads used in our daily life: resistive loads, capacitive loads, and inductive loads. For example, daily light bulbs are resistive loads; fluorescent lamps and energy-saving lamps are capacitive loads; electric fans are inductive loads. Because the waveform output by the early inverter is a modified square wave, and the circuit is relatively simple, it can only be used in vehicles. UPS, backup power supply, etc., there are many types of loads that cannot be used normally. If it can be used normally, there must be a power supply to change its output waveform into a pure sine wave (civilian grid wave type), and the existing inverter shells are smooth, and a large-area heat sink needs to be added Help dissipate the heat generated when the inverter works, resulting in bulky product, complicated process, high cost and poor heat dissipation performance.

Utility model content:

The purpose of the utility model is to provide an inverter that is easy to use and has good heat dissipation performance in view of the shortcomings of the existing inverter appearance technology.

In order to achieve the above object, the technical solution adopted by the utility model is:

An inverter, including a finned housing, the two ends of the housing are respectively provided with an AC output panel and a DC input panel, and the DC input panel is provided with a DC input connector, a USB interface for providing USB power, and an AC power input panel. The output panel is provided with an AC output socket, and the outer surface of the shell is provided with a plurality of heat dissipation fins.

The direct current input panel is provided with an access terminal.

A switch is provided on the AC output panel.

Both the AC output panel and the DC input panel are provided with ventilation holes.

The surface of the heat dissipation fins has a corrugated structure.

The beneficial effect of the utility model is that: the utility model includes a heat dissipation fin housing, the two ends of the housing are respectively provided with an AC output panel and a DC input panel, the AC output panel is provided with an AC output socket, and the DC input panel is provided with The DC input connector and the USB interface used to provide USB power are convenient for the use of various types of power interface devices. The outer surface of the shell is provided with a number of heat dissipation fins, which can effectively increase the heat dissipation area of the shell, so that the The heat inside the inverter can be dissipated as soon as possible, the heat dissipation performance is good, and the volume is small, and the installation is convenient and quick.

Detailed ways:

The utility model will be further described below in conjunction with the accompanying drawings. As shown in Figures 1 to 2, an inverter includes a heat dissipation fin housing 1, and the two ends of the housing 1 are respectively provided with an AC output panel 2, a DC power The input panel 3 and the AC output panel 2 are provided with an AC output socket 6, and the DC input panel 3 is provided with a DC input connector 4 and a USB interface 5 for providing USB power, which facilitates the use of various power interface types of equipment.

The direct current input panel 3 is provided with an access terminal to facilitate the wiring of direct current input. The AC output panel 2 is provided with a switch 8 for convenient control of the power supply.

Both the AC output panel 2 and the DC input panel 3 are provided with ventilation holes 9 to improve the heat dissipation effect. Aiming at the fact that the inverter itself will generate a lot of heat due to its operation, a plurality of heat dissipation fins 11 are protruding outward on the outer surface of the housing 1, and the two ends of the heat dissipation fins 11 extend to the two ends of the housing 1 respectively, which can The heat dissipation area of the casing 1 is effectively increased, so that the heat inside the inverter can be dissipated as soon as possible. The surface of the heat dissipation fins 11 has a corrugated structure, which further increases the heat dissipation area of the housing 1 and improves the heat dissipation effect. Compared with the huge volume and cooling parts of the existing inverter, the utility model has a smaller volume, more convenient and fast installation, and saves complicated wiring and installation costs.

Of course, the above are only preferred embodiments of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the utility model patent application are included in the utility model patent application within range.
