Embodiment Construction

[0028] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, so as to understand the essence of the present invention more clearly and intuitively.

[0029] refer to Figure 1 to Figure 3 As shown, the embodiment of the present invention provides a long-life low-power zero-noise photovoltaic inverter, including a housing, a circuit board 30 and a heat dissipation cover.

[0030] The housing is provided with a first ventilation structure for dissipating heat inside the housing. The circuit board 30 is arranged inside the casing, and generates a lot of heat under working conditions. The heat dissipation cover is made of aluminum, and the heat dissipation cover is fixedly installed inside the housing, and is arranged above the circuit board 30 to absorb the heat released by the circuit board 30; the heat dissipation cover is also provided with the first ventilation structure The ...

Abstract

The invention relates to a photovoltaic inverter with the long service life, low power consumption and zero noise. The photovoltaic inverter with the long service life, low power consumption and zero noise comprises a shell, a circuit board and a heat dissipation cover board, wherein a first ventilation structure is arranged on the shell; the circuit board is arranged inside the shell; the heat dissipation cover board is made of aluminum materials, is fixedly installed inside the shell and is arranged above the circuit board; the heat dissipation cover board is provided with a second ventilation structure opposite to the first ventilation structure so that air convection can be carried out between the first ventilation structure and the second ventilation structure. According to the photovoltaic inverter with the long service life, low power consumption and zero noise, the heat dissipation cover board made of the aluminum materials serves as a radiator, and the photovoltaic inverter has the advantages of the long service life, low energy consumption, zero noise, low cost and the like.

Description

technical field [0001] The invention relates to an inverter, in particular to a vehicle-mounted long-life, low-power consumption and zero-noise photovoltaic inverter. Background technique [0002] The car inverter (power converter, Power Inverter) is a kind of convenient car power converter that can convert DC12V direct current into AC220V alternating current, which is the same as mains power, for general electrical appliances. Vehicle inverters are generally welcomed in foreign markets. Due to the high penetration rate of automobiles in foreign countries, the inverter can be used to connect the battery to drive electrical appliances and various tools to work when going out to work or travel. After China entered the WTO, there are more and more private vehicles in the domestic market. Therefore, as a DC-to-AC converter used in mobile, the vehicle-mounted inverter will bring a lot of convenience to people's life and is a kind of standing vehicle. Equipment for automotive el...
