Technical Field

[0001] The utility model relates to the technical field of air compressor frequency converters, in particular to an overheat-proof energy-saving air compressor frequency converter. Background Art

[0002] The air compressor inverter is an electrical device used to perform frequency conversion on the air compressor to achieve stable and reliable air supply pressure of the air compressor. It is an important part of the air compressor system. Through the pressure regulator, the air compressor can maintain a stepless set pressure value. Usually, the air compressor inverter includes an inverter movement and a housing. The movement is composed of several electronic components and is arranged in the housing. The heat fan or cooling pipe on the housing is used to dissipate the heat of the movement.

[0003] However, during the use of traditional air compressor inverters, when the air compressor inverter is in a high-power working state, the cooling fan is difficult to dissipate heat quickly. When the air compressor inverter is working at a lower power, the temperature of the movement is low. The use of high-cost water cooling can easily lead to a waste of resources, making it difficult to adapt the heat dissipation power to the different powers of the air compressor inverter, resulting in a waste of resources or poor heat dissipation effect.

[0024] A cooling water tank 3 is fixedly connected to the top of the shell 1. A water pump 6 for providing water circulation power is fixedly arranged at the top of the shell 1. One end of the water pump 6 is connected to the inside of the cooling water tank 3 through a connecting pipe 7, and the other end of the water pump 6 is connected to the inside of the cooling water tank 3 through a heat dissipation water pipe 5 for dissipating heat from the inverter. The middle part of the heat dissipation water pipe 5 is arranged in the shell 1. Cooling water is arranged in the cooling water tank 3. When the water pump 6 is started, the cooling water is driven to circulate in the cooling water tank 3, the connecting pipe 7, the water pump 6 and the heat dissipation water pipe 5. When the cooling water passes through the heat dissipation water pipe 5 located in the shell 1, it drives the heat inside the inverter.

[0025] See also Figure 1-Figure 6 An air intake pipe 4 matching with the dustproof plate 8 is arranged on the outer side of the shell 1, and a No. 2 air intake groove 16 matching with the air intake pipe 4 is opened on one side of the shell 1. The shape and size of the No. 2 air intake groove 16 are consistent with the No. 1 air intake groove 15. One end of the air intake pipe 4 is fixedly connected with the cooling water tank 3, and the other end of the air intake pipe 4 is located at the position corresponding to the No. 2 air intake groove 16 and is located on the outer side of the dustproof plate 8. The pipe mouth of the air intake pipe 4 is adapted to the No. 2 air intake groove 16, and one end of the dustproof plate 8 is located between the No. 2 air intake groove 16 and the air intake pipe 4. The dustproof plate 8 blocks the No. 2 air intake groove 16 and the air intake pipe 4.

[0026] Two limit rods 12 are fixedly provided on one side of the shell 1, and the two limit rods 12 are respectively located at the top and bottom of the dustproof plate 8. The top and bottom ends of the dustproof plate 8 are fixedly connected with guide blocks 17. The limit rod 12 is provided with a guide groove 18 adapted to the guide block 17. The guide block 17 cooperates with the guide groove 18 of the limit rod 12 to make the dustproof plate 8 fit the outer wall of the shell 1 and slide relative to the shell 1. The height of the No. 1 air inlet groove 15 is consistent with the height of the No. 2 air inlet groove 16, and the sliding direction of the dustproof plate 8 is adapted to the height of the No. 1 air inlet groove 15 and the position of the No. 2 air inlet groove 16.

[0027] One end of the dustproof plate 8 is fixedly connected to a magnetic block 11, and one side of the shell 1 is fixedly connected to a connecting seat 9 for cooperating with the magnetic block 11. The connecting seat 9 is fixedly provided with an electromagnet 10 for cooperating with the magnetic block 11 near one end of the dustproof plate 8. The electromagnet 10 and the water pump 6 are both controlled by the movement of the inverter. The electromagnet 10 is used to pass direct current with different current directions. When the force between the electromagnet 10 and the magnetic block 11 is a repulsive force, the magnetic block 11 drives the dustproof plate 8 to move, and the dustproof plate 8 blocks the No. 1 air inlet groove 15, and moves the ventilation groove 13 to the outside of the No. 2 air inlet groove 16. The ventilation groove 13 connects the air inlet pipe 4 and the No. 2 air inlet groove 16. The air outside the shell 1 passes through the air inlet pipe 4, the ventilation groove 13 and the No. 2 air inlet groove 16 into the shell 1. Conversely, the force between the electromagnet 10 and the magnetic block 11 is an attractive force, so that the dustproof plate 8 is reset.

[0028] When the gas passes through the part of the intake pipe 4 located on the inner side of the cooling water tank 3, the water in the cooling water tank 3 reduces the temperature of the passing gas, making the temperature entering the shell 1 lower. At the same time, in conjunction with the water pump 6, the flow of cooling water in the ventilation groove 13 further improves the cooling efficiency of the gas in the intake pipe 4. A brush 14 adapted to the ventilation groove 13 is fixedly connected to one side of the two limit rods 12. The brush 14 is located between the No. 1 intake groove 15 and the No. 2 intake groove 16 and on the outside of the dustproof plate 8. When the dustproof plate 8 moves, the brush 14 can clean the surface of the ventilation groove 13 to prevent dust from clogging the ventilation groove 13 and reducing the intake efficiency.

[0029] The usage (working principle) of the utility model is as follows:

[0030] When the inverter works at a lower power, the ventilation groove 13 is located on the outside of the No. 1 air inlet groove 15, and the No. 2 air inlet groove 16 is blocked by the dustproof plate 8, and heat is dissipated by the heat dissipation fan 2. When the power of the inverter is increased to the set value, the electromagnet 10 is started, so that the force between the electromagnet 10 and the magnetic block 11 is a repulsive force, and the magnetic block 11 pushes the dustproof plate 8 to move. The ventilation groove 13 is moved to the position corresponding to the No. 2 air inlet groove 16 after being cleaned by the brush 14. The gas enters from the air inlet pipe 4 and enters the shell 1 through the ventilation groove 13 and the No. 2 air inlet groove 16. The cooling water tank 3 cools the gas passing through the air inlet pipe 4. When the power of the inverter is further increased, the No. 2 air inlet groove 16 is used to intake air and the heat is dissipated by the heat dissipation fan 2. At the same time, the water pump 6 is started, and the cooling water in the heat dissipation water pipe 5 is circulated to take away the heat in the inverter, and the flowing water in the cooling water tank 3 further improves the cooling efficiency of the gas in the air inlet pipe 4.
