Technical Field

[0002] The energy storage inverter can control the charging and discharging process of the battery and perform AC-DC conversion. It can directly supply power to the AC load in the absence of a power grid. The energy storage inverter is composed of a DC / AC bidirectional inverter, a control unit, etc. The controller receives background control instructions through communication, and controls the inverter to charge or discharge the battery according to the sign and size of the power instruction, thereby realizing the regulation of the active power and reactive power of the power grid. The PCS controller communicates with the BMS through the CAN interface to obtain the battery pack status information, which can realize protective charging and discharging of the battery and ensure the safe operation of the battery.

[0003] In the prior art, there is an energy storage inverter such as CN218352392U disclosed on the Chinese patent website, which is convenient for dissipating heat for electrical components inside the energy storage inverter and has a better heat dissipation effect. It can filter and dehumidify the air entering from the outside to prevent the electrical components from being corroded. However, the heat dissipation fins and cooling pipes of this heat dissipation mechanism are only arranged directly below the electrical components and are located in the same direction as the heat dissipation fan, so that the heat dissipation and cooling effects of the heat dissipation fins and cooling pipes overlap, and the heat dissipation effect in other positions and directions of the electrical components is not good, thereby affecting the overall heat dissipation quality and the working efficiency of the device. Therefore, an energy storage inverter is proposed to solve the problems mentioned in the above background. Utility Model Content

[0025] See also Figure 1-3 The utility model provides the following technical solutions: an energy storage converter, comprising a fuselage structure 1, the fuselage structure 1 comprising a box 11, a partition 12 is fixedly arranged in the box 11, a bidirectional converter device 13 is fixedly installed on the inner wall of the box 11, and an air cooling structure 2 and a coolant assembly 3 are arranged in the box 11;

[0026] The air cooling structure 2 includes a micro motor 21 rotatably connected to the inner bottom wall of the box body 11. The micro motor 21 has its own power supply structure. A driving gear 22 is coaxially fixedly connected to the outer side of the micro motor 21 shaft. Two fan shafts 23 are rotatably connected to the inner bottom wall of the box body 11. The outer sides of the two fan shafts 23 are connected by a transmission belt 24. A driven gear 25 is coaxially fixedly connected to the outer side of the fan shaft 23 on the side close to the micro motor 21. The driven gear 25 is meshed with the driving gear 22. Cooling fans 26 are fixedly arranged on the outer sides of the two fan shafts 23.

[0027] Through the above technical scheme, by setting up the air-cooling structure 2 and the coolant assembly 3, during the operation of the energy storage inverter device, by starting the micro motor 21, the driving gear 22 drives the driven gear 25 to rotate. Under the transmission action of the transmission belt 24, the two fan shafts 23 start to rotate, thereby driving the cooling fan 26 to rotate. The rotation of the cooling fan 26 allows air to circulate inside the box 11, and performs air cooling and heat dissipation operations on the bottom of the components. At the same time, the coolant is added to the inside of the box 11 through the water inlet pipe 33, and the coolant flows through the serpentine cooling pipe 32 and then flows out through the water outlet pipe 34. During the flow process, the transparent heat sink 31 is used to dissipate heat and cool the components from both sides. Under the combined action of the air-cooling structure 2 and the coolant assembly 3, the components such as the bidirectional inverter device 13 are cooled from multiple directions, thereby improving the heat dissipation range and heat dissipation quality, thereby improving the overall working efficiency of the device.

[0028] Specifically, the coolant assembly 3 includes two transparent heat sinks 31 respectively fixedly connected to the two side walls of the box body 11, and serpentine cooling pipes 32 are fixedly arranged in the two transparent heat sinks 31. The top ends of the two serpentine cooling pipes 32 are connected to water inlet pipes 33, and the bottom ends of the two serpentine cooling pipes 32 are connected to water outlet pipes 34. The two water inlet pipes 33 and the water outlet pipes 34 all pass through the box body 11.

[0029] Through the above technical solution, by setting up the coolant assembly 3, it is possible to connect the water inlet pipe 33 to the external water pump and then connect it to the coolant tank. By starting the water pump, the water pump draws the coolant into the water inlet pipe 33, and then flows through the serpentine cooling pipe 32. The bidirectional converter device 13 and the control device and other components in the box body 11 are cooled and cooled through the transparent heat sink 31, and the components are cooled from both sides, ensuring that the working temperature inside the energy storage converter device is appropriate.

[0030] Specifically, a plurality of elongated square holes 14 are formed on the partition plate 12 .

[0031] Through the above technical solution, a plurality of elongated square holes 14 are opened on the partition 12, so that after the heat dissipation fan 26 in the air-cooling structure 2 rotates, air can enter the upper part of the box body 11 through the elongated square holes 14 for circulation operation, further improving the heat dissipation efficiency.

[0032] Specifically, both sides of the box body 11 are provided with empty slots, and both sides of the box body 11 are fixedly connected with heat sinks 16 through fixing bolts 15 , and both heat sinks 16 are provided with ventilation and heat dissipation nets 17 of the same size as the empty slots.

[0033] Through the above technical scheme, by setting the heat sink 16 and the ventilation and heat dissipation net 17, the outside air can enter the interior of the box 11 through the ventilation and heat dissipation net 17, thereby promoting the air circulation inside the box 11. At the same time, the dust in the outside air will remain on the ventilation and heat dissipation net 17 when passing through the ventilation and heat dissipation net 17, thereby preventing the dust from entering the interior of the box and causing damage to the components. By setting the heat sink 16 and the ventilation and heat dissipation net 17, when the cooling fan 26 rotates, the outside air enters the interior of the box 11 through the ventilation and heat dissipation net 17, thereby maintaining the air circulation inside the box 11 and promoting the heat dissipation efficiency. At the same time, the ventilation and heat dissipation net 17 plays a dustproof role, thereby preventing the dust from entering the interior of the box 11 and causing damage.

[0034] Specifically, the two water inlet pipes 33 and the water outlet pipe 34 are both sleeved and fixedly connected with a positioning ring 35 on the outside of the box body 11 .

[0035] Through the above technical solution, by providing the positioning ring 35, the water inlet pipe 33 and the water outlet pipe 34 can be positioned and fixed outside the box body 11, thereby ensuring the stability of the water inlet pipe 33 and the water outlet pipe 34.

[0036] Specifically, two switch doors 18 are rotatably provided on the outer side of the box body 11 .

[0037] Through the above technical solution, by setting the switch door 18, the operator can open the switch door 18 to inspect and replace the components and related structures inside the box body 11, which is very convenient and quick.

[0038] During use, during the operation of the energy storage converter device, by starting the micro motor 21, the driving gear 22 drives the driven gear 25 to rotate. Under the transmission action of the transmission belt 24, the two fan shafts 23 start to rotate, thereby driving the cooling fan 26 to rotate. The rotation of the cooling fan 26 allows air to circulate inside the box 11, and performs air cooling and heat dissipation operations on the bottom of the components. At the same time, coolant is added to the inside of the box 11 through the water inlet pipe 33, and the coolant flows through the serpentine cooling pipe 32 and then flows out through the water outlet pipe 34. During the flow, the transparent heat sink 31 is used to dissipate heat and cool the components from both sides. Under the combined action of the air cooling structure 2 and the coolant assembly 3, the components such as the bidirectional converter device 13 are cooled from multiple directions, thereby improving the heat dissipation range and heat dissipation quality, thereby improving the overall working efficiency of the device.
