[0028] Compared with the prior art, the split water channel structure of the air compressor provided by the utility model divides the water channel structure into two sections to achieve water cooling of the split air compressor casing structure. Each casing is provided with a water channel structure, and the two water channel structures are connected through the through hole 10 opened on the waterproof sealing gasket 11, so that water can enter from the flow pipe at the far end of one of the water channel structures, and the cooling water passes through the water channel structure, the through hole 10 and the other water channel structure in turn until it is discharged from the flow pipe at the far end of the other water channel structure, thereby completing the cooling of the two casing modules by the cooling water, solving the problem of poor cooling effect of the split air compressor, and the split water channel structure can facilitate the casting of the water channel and casing modules and the opening of the steel mold to save costs, further promoting the modularization and miniaturization development of the main casing products of the air compressor.

[0029] like Figure 2 As shown, the two-section water channel structure includes a first water channel structure located in the first shell module 2 and a second water channel structure located in the second shell module 3. The inlet end of the second water channel structure is connected to the outlet end of the first water channel structure via the through hole 10.

[0030] The first housing module 2 is connected to the control-end housing 1, and the second housing module 3 is connected to the pressure-end volute 4. The flow pipe connected to the first housing module 2 serves as the water inlet pipe, and the flow pipe connected to the second housing module 3 serves as the water outlet pipe. Cooling water enters the first water channel structure from the water inlet pipe, passes through the first water channel structure, enters the second water channel structure through the through hole 10, and enters the water outlet pipe at the outlet of the second water channel structure.

[0031] like Figures 3 to 7 As shown, the first water channel structure includes a water inlet section 5, a first cooling section 6 and a second cooling section 7 connected in sequence.

The water outlet end of the water inlet section 5 is connected to the first cooling section 6. The first cooling section 6 is a ring with a notch, which is used to cool the side of the first shell module 2 close to the control end shell 1. The first cooling section 6 has two ends, one of which is connected to the water inlet section 5, and the other end is connected to the water hole 9; the water hole 9 extends axially toward the first shell module 2; the second cooling section 7 is also a ring with a notch, which is used to cool the side of the first shell module 2 close to the waterproof sealing gasket 11; the two ends of the second cooling section 7, one end of which is connected to the water hole 9, and the other end extends to one side of the water inlet section 5, and makes way for the water inlet section 5 through the make way portion.
