Description

Technical Field

[0001] The utility model relates to the technical field related to air compressor cooling, in particular to a circulating water cooling device for a centrifugal air compressor. Background Art

[0002] In the structure of centrifugal air compressor, the foil gas dynamic pressure bearing and the rotor system are key components, which directly determine the performance of the air compressor. During the operation of the air compressor, it is very important to ensure the stability of the foil gas dynamic pressure bearing and the rotor system for the air compressor itself. During the operation of the machine, the rotor system will generate heat. The function of the foil gas dynamic pressure bearing is to limit the radial and axial movement of the high-speed rotating rotor. The higher the power of the air compressor, the greater the required rotor deadweight, and the corresponding power consumption and heat generation of the foil gas dynamic pressure bearing will also increase. Since heat will be generated during the operation of the rotor system, coupled with the heat generated by the foil gas dynamic pressure bearing, the heat generation of the entire air compressor reaches a relatively large level. If this heat is not well handled and always exists inside the air compressor, it will cause adverse effects on the air compressor. Since the internal rotor system of the centrifugal air compressor uses a permanent magnet synchronous motor, high temperature will cause the motor power to decrease, and in severe cases, the high temperature magnetism of the rotor will disappear. At the same time, excessive temperature of the foil gas dynamic pressure bearing will also cause the phenomenon of "burning bearings".

[0003] Chinese patent CN213392680U, authorized and announced on June 8, 2021, discloses a cooling device for a screw air compressor, wherein a slide groove is arranged on the left side of the inner wall of the cooling device housing case, and a cooling device is arranged in the slide groove. When the cooling device is pulled, the cooling device moves outward in the slide groove, thereby separating the cooling device from the cooling device housing, and then the rod is pulled outward, so that the pulling rod drives the spring to move downward, thereby separating the insertion rod from the slot, and then the fan blades are pulled outward, thereby achieving the effect of fan replacement. However, when the device is in use, on the air compressor test bench, conventional water-cooled heat dissipation devices can achieve the desired effect, but on the air compressor as a whole, due to the need to simultaneously meet the effects of streamlined structure and neat and beautiful appearance, conventional water-cooled heat dissipation devices cannot meet the above requirements, making it still relatively inconvenient when used.

To this end, the utility model proposes a centrifugal air compressor circulating water cooling device, which can simplify the structure of the water cooling and heat dissipation system, which is conducive to improving the reliability of the whole machine assembly.

[0033] Embodiment 1

[0034] See also Figure 1 - Figure 3 As shown in the figure, a centrifugal air compressor circulating water cooling device includes a water tank 100 and a heat sink 200. The heat sink 200 is installed on the outer wall of the water tank 100. A water inlet 300 is fixedly connected to the outer wall of the water tank 100. A water outlet 400 is fixedly connected to the outer wall of the water tank 100. A heat sink assembly 600 is mounted on the outer wall of the water tank 100. A purification assembly 800 is mounted on the outer wall of the heat sink assembly 600.

[0035] The heat dissipation component 600 includes a water pump 601, which is installed on the surface of the water tank 100. A water suction port 602 is fixedly connected to the outer wall of one end of the water pump 601. A heat dissipation pipe 603 is installed on the inner wall of the heat dissipation box 200. A water injection port 604 is fixedly connected to the outer wall of one end of the heat dissipation pipe 603. A motor 605 is installed on the outer wall of the heat dissipation box 200. A heat dissipation blade 606 is fixedly connected to the outer wall of one end of the motor 605.

[0036] When in use, first move the device to one side of the air compressor through the hanging ring 500 on the surface of the heat sink 200, then connect the water inlet 300 and the water outlet 400 to the air compressor, so that the condensed water inside the air compressor flows into the water tank 100 through the water inlet 300, then connect the external power supply to start the water pump 601, so that the condensed water is injected into the water inlet 604 through the water pump 602 and the water pipe. When the condensed water enters the heat pipe 603, start the motor 605 to drive the heat sink blade 606 to rotate. The wind generated by the rotation of the heat sink blade 606 blows toward the surface of the heat pipe 603 and takes away the heat of the heat pipe 603. Finally, the hot air is blown out of the heat sink 200 through the filter 700, thereby completing the heat dissipation of the condensed water and improving the overall usability of the device.

[0037] See also Figure 4 - Figure 5As shown in the figure, based on the first embodiment, the purification component 800 includes a block 801, which is mounted on the surface of the heat dissipation component 600, and a connection sleeve 804 is engaged on the surface of the block 801. A slot 805 is provided on the inner wall of the connection sleeve 804, and a connection pipe 803 is slidably connected to the outer wall of the connection sleeve 804. A rubber ring 802 is bonded to the outer wall of one end of the connection pipe 803, which can improve the sealing of the connection between the connection pipe 803 and the heat dissipation pipe 603. A purification pipe 806 is slidably connected to the outer wall of the connection pipe 803, and a spring 807 is fixedly connected to the outer wall of one end of the connection pipe 803, and one end of the spring 807 is fixedly connected to the inner wall of the purification pipe 806, so that the spring 807 can push the connection pipe 803 to reset when the connection pipe 803 is not subjected to external force.

[0038] During use, based on Example 1, when the condensed water flows to the tail of the heat dissipation pipe 603, it will enter the interior of the purification pipe 806. The filter cotton sheet, activated carbon filter tube and ultrafiltration membrane arranged inside the purification pipe 806 can purify and sterilize the condensed water, remove harmful substances such as dust, bacteria and viruses in the condensed water, and finally flow back from the heat dissipation pipe 603 to the interior of the water tank 100. When the purification pipe 806 needs to be replaced, it is only necessary to rotate the connecting sleeve 804 to slide the block 801 out of the slot 805, and then push the connecting pipe 803 to make the connecting pipe 803 slide inside the purification pipe 806, so that the purification pipe 806 can be separated from the heat dissipation pipe 603, thereby improving the overall usability of the device.

[0039] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and the concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
