Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, and in particular to a photovoltaic energy storage inverter. Background Art

[0002] In photovoltaic power generation technology, the inverter used to convert the DC power generated by photovoltaic modules into AC power is a key component of the entire photovoltaic power generation technology.

[0003] In order to dissipate heat from the inverter, the related art places the inductor with the inductor in the inverter outside the chassis to facilitate heat dissipation. However, in order to achieve a better heat dissipation effect, the inductor usually needs to be a molded aluminum inductor. When the power of the inverter increases, the temperature of the local air outlet on the top of the inductor rises sharply, and the size and weight of the radiator need to be increased, which will sharply increase the cost of the inverter. At the same time, it will cause the internal PCB board area to increase and the space utilization rate to be low. All of these will increase the production cost of the inverter, and will cause the assembly time of the inverter to be extended and the production efficiency to be reduced.

[0004] While meeting the heat dissipation requirements of high-power high-voltage boxes, reducing the heat dissipation cost is currently an urgent issue to be solved. Utility Model Content

[0032] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0033] For examples, see Figure 1-Figure 3 At least one embodiment provides a photovoltaic energy storage inverter, including: a box 100, a heat sink 200, a PV inductor 300 and an inverter inductor 400; the heat sink 200 is fixedly arranged on the outer shell of the box 100; the heat sink 200 includes a heat sink body 210 and N heat sink boxes 220, where N is greater than or equal to 2; the N heat sink boxes 220 are distributed on both sides of the heat sink body 210; the PV inductor 300 and the inverter inductor 400 are embedded and snapped into the corresponding heat sink boxes 220. By embedding and snapping the PV inductor 300 and the inverter inductor 400 into the corresponding heat sink boxes 220, natural heat dissipation is achieved. The N heat sink boxes 220 are distributed on both sides of the heat sink body 210, and uniform heat dissipation is achieved.

[0034] The radiator 200 is fixedly arranged at the bottom of the box 100. By fixing the radiator 200 at the bottom of the box 100, the size of the photovoltaic energy storage inverter is compressed, the volume of the inverter is reduced, and thus the space utilization is increased.

[0035] In some embodiments, a first waterproof strip 230 is provided between the radiator 200 and the box 100. By providing the first waterproof strip 230, the radiator 200 and the box 100 are sealed to prevent water vapor from entering the box 100 and affecting the operation of the photovoltaic energy storage inverter.

[0036] In some embodiments, the heat dissipation box 220 is provided with a receiving groove 221; the PV inductor 300 and the inverter inductor 400 are fixedly disposed in the corresponding receiving groove 221. The PV inductor 300 and the inverter inductor 400 are packaged through the receiving groove 221 to complete the sealing of the PV inductor 300 and the inverter inductor 400.

[0037] In at least one embodiment, the box 100 includes: a first circuit board 120 and a second circuit board 130; the first circuit board 120 and the second circuit board 130 are stacked. By providing two layers of circuit boards, the overall size of the box 100 is reduced, the production cost is reduced, and the space utilization rate is increased.

[0038] The power inverter circuit is arranged on the first circuit board 120. The output circuit and the control circuit are arranged on the second circuit board 130. The circuit of the photovoltaic energy storage inverter is divided into two parts according to the functional modules, which are arranged on the first circuit board 120 and the second circuit board 130 respectively, thereby optimizing the wiring layout.

[0039] It should be noted that the first circuit board 120 is disposed above the second circuit board 130 .

The box 100 is bottomless, and the radiator 200 is directly used as the bottom plate of the box 100, so that the inside of the box 100 is directly in contact with the radiator 200, thereby improving the heat dissipation effect of the box 100. At the same time, the box 100 is topless, which facilitates the first circuit board 120 and the second circuit board 130 to be placed in the box 100, thereby improving the assembly efficiency.

[0041] In order to prevent water vapor from entering between the box body 100 and the upper cover 500 , in some embodiments, a second waterproof strip 110 is provided between the box body 100 and the upper cover 500 .

[0042] In summary, the utility model provides a photovoltaic energy storage inverter, including: a box 100, a radiator 200, a PV inductor 300 and an inverter inductor 400; the radiator 200 is fixedly arranged on the outer shell of the box 100; the radiator 200 includes a radiator body 210 and N heat dissipation boxes 220, wherein N is greater than or equal to 2; the N heat dissipation boxes 220 are distributed on both sides of the radiator body 210; the PV inductor 300 and the inverter inductor 400 are embedded and snapped into the corresponding heat dissipation boxes 220. By embedding and snapping the PV inductor 300 and the inverter inductor 400 into the corresponding heat dissipation boxes 220, natural heat dissipation is achieved, and the influence of the heat dissipated by the PV inductor 300 and the inverter inductor 400 when working on the inside of the box 100 is reduced. At the same time, the N heat dissipation boxes 220 are distributed on both sides of the radiator body 210 to achieve uniform heat dissipation.
