[0002] Photovoltaic inverter is an inverter that can convert the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency, which can be fed back to the commercial power transmission system or used for off-grid power grids. Photovoltaic inverter is one of the important system balances in the photovoltaic array system and can be used with general AC power supply equipment. During the use of photovoltaic inverter, due to the continuous input and output of current, the photovoltaic inverter will generate a lot of heat, so it is necessary to dissipate the heat of the photovoltaic inverter in time to avoid the high temperature from having a greater impact on the inverter.

[0003] However, the existing photovoltaic inverter housing with high heat dissipation efficiency has the following defects: for example, the existing photovoltaic inverter housing relies on natural wind to dissipate heat during heat dissipation. Although this can achieve the purpose of heat dissipation, the heat dissipation effect is not obvious, thereby affecting the service life of the photovoltaic inverter. Summary of the invention

[0012] Further preferably, a circular hole is opened on the upper end surface of the shell, and the circular hole corresponds to the fixing tube.

[0013] Compared with the prior art, the beneficial effects of this application are:

[0014] By setting up the ventilation assembly, when heat dissipation is needed, the ventilation assembly can drive the outside air into the shell. With the entry of the outside air, the hot air inside the shell can be squeezed out from the ventilation holes on both sides of the shell, thus achieving the purpose of efficient heat dissipation, thereby increasing the service life of the photovoltaic inverter;

[0026] like Figure 1-5 A photovoltaic inverter housing with high efficiency in heat dissipation is shown, comprising a housing 1, a shell cover 5 being fixedly connected to the front end of the housing 1, a ventilation assembly 4 being arranged at the upper end of the housing 1, ventilation holes 2 being opened on both sides of the housing 1, and adjustment assemblies being arranged on both sides inside the housing 1, and the adjustment assemblies being used to adjust the size of the ventilation holes 2.

[0027] Specifically, when heat dissipation is needed, the adjustment component is first used to maximize the ventilation area of ​​the ventilation hole 2, and then the ventilation component 4 can work to drive the outside gas into the shell 1. With the entry of the outside gas, the hot air inside the shell 1 can be squeezed out from the ventilation holes 2 on both sides of the shell 1, thereby achieving the purpose of efficient heat dissipation, thereby increasing the service life of the photovoltaic inverter.

[0028] The lower end surface of the shell 1 is provided with a threading hole 7, and there are multiple threading holes 7, which are evenly distributed at the lower end of the shell 1. During operation, the threading holes 7 are provided to facilitate the wires to enter and exit the shell 1.

When working, the fan 403 can drive the outside air into the shell 1, thereby squeezing the hot air inside the shell 1 to be discharged outward, which is conducive to achieving the purpose of efficient heat dissipation.

[0030] The upper end of the fixed cylinder 401 is fixedly connected with a filter screen 11 . When working, the filter screen 11 is set so that the incoming air can be filtered to prevent dust from entering the interior of the housing 1 .

[0031] The adjusting assembly includes a sealing plate 8, an electric telescopic rod 9 and a connecting rod 10. The bottom end of the shell 1 is fixedly connected with the electric telescopic rod 9, and the extended end of the electric telescopic rod 9 is fixedly connected with the sealing plate 8. There are multiple sealing plates 8, which correspond to the ventilation holes 2 one by one. Two adjacent sealing plates 8 are fixedly connected by the connecting rod 10; a receiving groove 12 is provided on the inner wall of the shell 1, and the receiving groove 12 is located at the lower end of the ventilation hole 2 and corresponds to the ventilation hole 2 one by one. The sealing plate 8 is located inside the receiving groove 12 and is slidably connected to the receiving groove 12. When working, when rapid heat dissipation is required, the electric telescopic rod 9 is retracted, thereby driving the sealing plate 8 to move downward, and then with the cooperation of the connecting rod 10, all the ventilation holes 2 can be enlarged, which is conducive to the heat dissipation, thereby further improving the heat dissipation effect; when the heat dissipation operation is not performed, the electric telescopic rod 9 is extended, thereby driving the sealing plate 8 to move upward, so that the sealing plate 8 closes the ventilation hole 2, thereby preventing impurities from entering the shell 1.

[0032] Rain shields 3 are fixedly connected to both sides of the shell 1. There are multiple rain shields 3, which correspond to the ventilation holes 2 one by one. When working, the rain shields 3 can prevent rainwater from entering the shell 1 under the action of the rain shields 3.

[0033] The rear end of the shell 1 is fixedly connected with a mounting seat 6, and two mounting seats 6 are provided and symmetrically distributed on both sides of the rear end of the shell 1. When working, by setting the mounting seat 6, the shell 1 can be conveniently fixed at a desired place under the action of the mounting seat 6.

[0034] A circular hole is provided on the upper end surface of the shell 1, and the circular hole corresponds to the fixing tube 401. When working, the circular hole is provided to facilitate the installation of the fan 403, and also facilitate the fan 403 to blow the outside air into the shell 1, which is conducive to better heat dissipation.

[0035] Working principle: When in use, the electric telescopic rod 9 contracts, thereby driving the sealing plate 8 to move downward, and then with the cooperation of the connecting rod 10, all the ventilation holes 2 can be enlarged, and then the fan 403 can work to drive the outside air into the shell 1, thereby squeezing the hot air inside the shell 1 to be discharged from the ventilation holes 2 on both sides of the shell 1, thereby achieving the purpose of efficient heat dissipation, thereby increasing the service life of the photovoltaic inverter; when no heat dissipation is performed, the electric telescopic rod 9 extends, thereby driving the sealing plate 8 to move upward, so that the sealing plate 8 closes the ventilation holes 2, thereby preventing impurities from entering the shell 1.
