Description

Technical Field

[0001] The utility model relates to the technical field of noise-proof structures of rectifiers, in particular to a noise-proof structure of a rectifier. Background Art

[0002] The inverter for photovoltaic water pump is a power control device specially designed for photovoltaic water pump system. Its core function is to convert the direct current generated by photovoltaic modules into alternating current that can directly drive the water pump, so as to control and regulate the operation of the photovoltaic water pump system. The photovoltaic water pump system is mainly composed of photovoltaic solar panels, special inverters, water pumps, water storage devices, etc. The system uses semiconductors to absorb solar radiation energy, converts it into direct current, and then converts it into alternating current through photovoltaic inverters to drive water pumps to pump water. In arid and semi-arid areas, this system can solve the problem of water extraction difficulties and promote local development.

[0003] The rectifier is a key component in the inverter. It is responsible for sorting the DC power generated by the photovoltaic module to ensure the stability and quality of the current for the subsequent inversion process. In the photovoltaic water pump system, the photovoltaic panel receives solar radiation and generates DC power. However, this DC power often fluctuates and is unstable, and cannot be used directly to drive the water pump motor. At this time, the role of the rectifier is particularly important. The rectifier smoothes the DC power through its internal semiconductor devices, eliminates the pulsation and noise in the current, and obtains a smooth and high-quality DC power. This process ensures the stability and reliability of the DC power and provides a good power supply foundation for the subsequent inversion process.

[0004] However, heat is generated during the operation of the rectifier. If the heat cannot be sufficiently dissipated, it will cause compression and expansion of components, thereby generating noise. In view of this, the present application proposes a noise-proof structure of the rectifier. Utility Model Content

[0010] Furthermore, a rotating shaft is rotatably mounted on one side of the mounting plate located inside the heat dissipation cover, a heat dissipation fan is fixedly mounted on the surface of the rotating shaft, and the rotating shaft rotates and penetrates the heat dissipation network pipe.

[0031] The heat dissipation assembly includes a fixing rod 7 fixedly mounted on the inner wall of the heat dissipation cover 6 , and a heat dissipation network pipe 8 is fixedly mounted on one end of the fixing rod 7 .

[0033] At the same time, a 'M' mounting frame 9 is fixedly installed on the inner wall of the heat dissipation cover 6 away from the sound insulation shell 1 , a mounting plate 10 is fixedly installed in the middle of the 'M' mounting frame 9 , and an air inlet 61 is opened on the surface of the heat dissipation cover 6 close to the sound insulation shell 1 .

[0040] The above solution of the utility model includes at least the following beneficial effects:

[0041] The anti-noise structure of the rectifier is to isolate noise by wrapping the surface of the heat dissipation shell and the heat sink outside the rectifier with a soundproof shell. At the same time, a heat-absorbing half-tube is arranged on the surface of the heat sink, and a heat dissipation network pipe is arranged inside the heat dissipation cover. The heat on the heat sink is brought out by cooling water in the heat-absorbing half-tube and the heat dissipation network pipe, thereby improving the heat dissipation effect and preventing the possibility of noise generation. This solves the problem that heat will be generated during the operation of the rectifier. If sufficient heat dissipation cannot be obtained, it will cause compression and expansion of components, thereby generating noise.
