Description

Technical Field

[0001] The present application relates to the technical field of air compressors, and in particular to an air outlet rack for an air compressor. Background Art

[0002] An air compressor is a machine that compresses air from the atmosphere into high-pressure gas for use in pneumatic equipment or tools.

[0003] When air is compressed in the air machine, a large amount of heat will be generated. This heat will cause the temperature of the air compressor to rise, especially the air outlet of the air compressor will continue to be affected by the high-level gas. If the heat is not dissipated and cooled in time, the pressure difference between the air pressure at the air compressor outlet and the air compressor inlet will increase, resulting in an increase in the compression energy consumption of the air compressor and a decrease in the compression efficiency of the air compressor.

[0029] Example 1

[0030] Reference Figure 1-Figure 4 This embodiment provides a cooling system for an air compressor outlet rack 1, including an air outlet rack 1, on which an air guide pipe 2 is arranged.

[0031] The air guide tube 2 is configured as a double-layer air guide tube 2 structure, and the inner and outer layers of the double-layer air guide tube 2 structure are respectively referred to as the inner tube and the outer tube; a sealed cavity is formed between the inner tube and the outer tube, which is referred to as a cooling water cavity; at least two interfaces connected to the cooling water cavity are provided on the outer tube, which are respectively referred to as a water inlet 3 and a water outlet 4; a water cooling system is also included; the water cooling system includes a water injection pipe 5 and a water return pipe 6, the water injection pipe 5 is connected to the water inlet 3, and the water return pipe 6 is connected to the water outlet 4; the water cooling system also includes a water pump 7, the water suction port of the water pump 7 is connected to the water return pipe 6, and the water discharge port of the water pump 7 is connected to the water injection pipe 5, so that the water suction port of the water pump 7 is connected to the water return pipe 6. The water outlet 4 is connected, and the drain outlet of the water pump 7 is connected to the water inlet 3. By arranging an inner tube and an outer tube on the air outlet frame 1, a cooling water cavity is formed between the inner tube and the outer tube. When the air compressor is working, cooling water can be injected into the cooling water cavity to cool the air passing through the inner tube, thereby reducing the pressure difference between the air pressure at the air compressor outlet and the air compressor inlet, reducing the compression energy consumption of the air compressor, and improving the compression efficiency of the air compressor. Secondly, a water cooling system is arranged in the tube wall of the cooling pipe, and water is injected into the cooling water cavity through the water inlet 3, and the hot water is discharged through the water outlet 4. The water pump 7 is used to drive the water flow to continuously cool the air outlet frame 1, and the hot air in the air guide pipe 2 is continuously cooled, thereby improving the continuous cooling effect of the air guide pipe 2.

[0032] The water inlet 3 of the cooling water chamber is arranged below the outer tube, and the water outlet 4 of the cooling water chamber is arranged above the outer tube; the water inlet 3 is arranged at the lower end of the outer tube and the water outlet 4 is arranged at the upper end of the air guide tube 2, and the water is discharged after filling the cooling water chamber, ensuring that the water can flow in the cooling water chamber and fill every corner of the cooling water chamber, thereby improving the heat dissipation efficiency of the air guide tube 2, thereby reducing the compression energy consumption of the air compressor.

[0033] The air duct 2 is made of copper. The use of copper ensures the thermal conductivity of the air duct 2 and improves the heat dissipation capacity of the air duct 2, thereby reducing the compression energy consumption of the air compressor.

[0034] The water cooling system also includes a cooling row 10, the return water pipe 6 is coiled in the cooling row 10, and the cooling row 10 is also provided with a fan, and the air outlet of the fan is directed toward the return water pipe 6 in the cooling row 10; the return water pipe 6 is made of copper; by arranging a cold water row in the return water pipe 6 in the water cooling system, the heat dissipation efficiency of the water cooling system is improved, thereby ensuring the continuous cooling effect of the air duct 2.

[0035] When in use, the air duct 2 is connected to the air outlet frame 1 of the air compressor by bolts. After the air duct 2 is installed, the water inlet 3 faces downward and the water outlet 4 faces upward. The water injection pipe 5 of the water cooling system is connected to the water inlet 3, and the water return pipe 6 of the water cooling system is connected to the water outlet 4. When the temperature at the air duct 2 rises and needs to be cooled, the water cooling system is started, and the water pump 7 in the water cooling system drives water to be injected into the water injection pipe 5 from the water outlet, and then injected into the cooling water cavity of the air duct 2 from the water injection pipe 5. After the cooling water cavity is filled with water, it flows into the return water pipe 6 from the water outlet 4 at the upper end of the cooling water cavity. After the water in the return water pipe 6 is cooled by the cooling row 10, it is driven by the water pump 7 again to flow from the water injection pipe 5 into the cooling water cavity to cool the cooling pipe, cool the air discharged from the air duct 2, reduce the pressure difference between the air pressure at the air compressor outlet and the air compressor inlet, reduce the compression energy consumption of the air compressor, and improve the compression efficiency of the air compressor.

[0036] Example 2

[0037] refer to Figure 1 and Figure 2 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0038] A rack structure 8 is arranged on the inner side wall of the inner tube, and the rack structure 8 is arranged along the direction of gas flow in the inner tube. By arranging the rack structure 8 along the direction of the air guide hole on the side wall of the air guide hole, the contact area between the inner wall of the air guide hole and the hot air in the air guide hole is increased, thereby improving the heat dissipation effect of the air guide tube 2.

[0039] A copper sheet structure surrounding the inner tube is arranged on the outer side wall of the inner tube, which is called fin 9; the thickness of the fin 9 is 1-2 mm; the spacing between the fins 9 is 2-5 mm; by providing the fin 9, the contact area between the water in the cooling water chamber and the heat-generating side wall can be increased when the water flows, so that the flowing water can take away more heat, thereby improving the heat dissipation effect of the air guide tube 2.

[0040] The water cooling system also includes a water tank, the water pump 7 is connected to the water tank, the return water pipe 6 is injected into the water tank through the cold water drain, the water suction port of the water pump 7 absorbs the water in the water tank, and the water injection pipe 5 is connected and communicated with the discharge port of the water pump 7; by setting up the water tank, more cooling water can be injected into the water tank, thereby ensuring the continuous cooling effect of the air duct 2.

[0041] When in use, the water pump 7 is placed in the water tank, and the return pipe 6 is connected to the water tank. The water suction port of the water pump 7 absorbs the water in the water tank, so that the cooling water of the water cooling system can be replaced, thereby avoiding the formation of scale and extending the service life of the air duct 2. The heat dissipation effect of the air duct 2 is improved by arranging the fins 9 and the rack structure 8, and the air discharged from the air duct 2 is cooled, thereby reducing the pressure difference between the air pressure at the air outlet of the air compressor and the air pressure at the air inlet of the air compressor, reducing the compression energy consumption of the air compressor, and improving the compression efficiency of the air compressor.
