Description

Technical Field

[0001] The utility model relates to the technical field of magnetic suspension fans, in particular to a circulating cooling magnetic suspension air compressor. Background Art

[0002] With the development of blowing technology, magnetic levitation fans have emerged. Magnetic levitation fans generate wind by energizing the fan stator to drive the rotor to drive the impeller to rotate. Since the stator will heat up when energized, overheating will cause damage to the fan. In traditional technology, magnetic levitation fans use a separate cooling fan to supply air for cooling. In actual use, this air cooling method has gradually been found to have a cooling effect that cannot meet the needs, which will cause the motor and inverter to have high temperatures, thereby affecting the use effect of the air compressor. Due to the limited space inside the chassis, it is not realistic to install multiple cooling fans. How to effectively utilize the circulating refrigeration of the traditional water cooling method to replace the fan cooling method? Therefore, a circulating cooling magnetic levitation air compressor is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a circulating cooling magnetic levitation air compressor to solve the problem of cooling the compression motor and the inverter during the use of the air compressor in the prior art.

[0004] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0005] A circulating cooling magnetic levitation air compressor, comprising:

[0006] A chassis, wherein a compressor body is provided in the chassis, a water cooling box is provided at the bottom of the compressor body, and a water inlet pipe and a water outlet pipe connecting the inside of the water cooling box with the outside are provided on the water cooling box;

[0007] A water tank is provided on one side of the compressor body, a cold water pipe is provided at the output end of the water tank, and a return water pipe is provided at the input end of the water tank. The cold water pipe and the return water pipe are respectively connected to the compression motor and the inverter, and the cold water pipe and the return water pipe form a circulation pipeline.

[0008] To implement the above technical solution, a water cooling box is set up to cool the compressed air to avoid excessively high compressed air temperature, which affects the subsequent normal use of the compressed air. The water cooling box is provided with a water inlet pipe and a water outlet pipe connecting the inside of the water cooling box with the outside world. The water circulation cooling method can be used to ensure that the water cooling box always maintains a constant temperature, thereby improving the cooling effect of the water cooling box on the compressed air.

[0009] By setting up a water tank on one side of the compressor body, and connecting the cold water pipe at the output end and the return water pipe at the input end of the water tank to the compression motor and inverter respectively, a circulation pipeline is formed by using the cold water pipe and the return water pipe to cool the compression motor and inverter, thereby avoiding the compression motor and inverter from overheating.

[0010] In one embodiment of the present invention, a plate heat exchanger is provided on one side of the water tank, and a heat exchange pipe is provided on the plate heat exchanger, which is respectively connected to the water inlet pipe and the water outlet pipe. The return pipe is connected to the plate heat exchanger, and the circulating coolant in the return pipe flows back to the return tank after passing through the plate heat exchanger.

[0011] To implement the above technical solution, a plate heat exchanger is provided, and the heat exchange tubes on the plate heat exchanger are used to connect the water inlet pipe and the water outlet pipe respectively, so as to achieve a constant temperature state inside the plate heat exchanger, so that the circulating coolant in the return pipe flows back to the return water tank after passing through the plate heat exchanger, and the coolant flowing back to the water tank can achieve a cooling effect, thereby reducing the temperature of the coolant in the water tank.

[0012] In one embodiment of the present invention, the return pipe is connected to the bottom side of the plate heat exchanger, and a return pipe is connected between the upper side of the plate heat exchanger and the water tank. The return pipe drains the coolant after heat exchange in the plate heat exchanger into the water tank.

[0013] To implement the above technical solution, the return pipe is connected to the bottom side of the plate heat exchanger, and the return pipe is arranged on the upper side of the plate heat exchanger, which can ensure that the coolant returning in the return pipe is fully in contact with the plate heat exchanger, thereby achieving a cooling effect on the coolant and ensuring the subsequent cooling treatment of the compressor motor and inverter by the coolant.

[0014] In one embodiment of the present invention, the coolant in the water tank is antifreeze or distilled water.

[0015] To implement the above technical solution, in order to ensure that the compression motor and the inverter are not damaged during the cooling process, circulating water cannot be used directly for cooling. To avoid the influence of impurities on the compression motor and the inverter, antifreeze or distilled water is needed to ensure the cleanliness of the compression motor and the inverter during the cooling process.

[0016] In one embodiment of the present invention, a cooling pump is provided on the cold water pipe between the output end of the water tank and the compression motor and the frequency converter, and the cooling pump drives the coolant in the cold water pipe to circulate.

[0017] To implement the above technical solution, a cooling pump is provided to drive the circulation of the coolant, thereby ensuring the stability of the coolant's cooling treatment of the compression motor and the inverter.

[0018] In one embodiment of the present invention, the compressed air in the compressor body is cooled in a water cooling box before being discharged.

[0019] By implementing the above technical solution, the cooled compressed air can reduce the gas temperature, thereby ensuring the stability and reliability of subsequent compressed gas use.

[0020] As described above, the utility model provides a circulating cooling magnetic levitation air compressor, which has the following beneficial effects: by providing a water cooling box to cool the compressed air, the compressed air temperature is prevented from being too high, which affects the normal use of the subsequent compressed air. The water cooling box is provided with a water inlet pipe and a water outlet pipe connecting the inside of the water cooling box with the outside world. The water circulation cooling method can be used to achieve that the water cooling box always maintains a constant temperature state, thereby improving the cooling effect of the water cooling box on the compressed air.

[0021] By setting up a water tank on one side of the compressor body, and connecting the cold water pipe at the output end and the return water pipe at the input end of the water tank to the compression motor and inverter respectively, a circulation pipeline is formed by using the cold water pipe and the return water pipe to cool the compression motor and inverter, thereby avoiding the compression motor and inverter from overheating.
