[0002] The compressor is used to compress the gas, and the compressor usually needs to be equipped with a cooling system to assist the operation of the compressor.

[0037] The present application embodiment provides a compression device using air cooling to dissipate heat, see Figures 1 to 4 As shown, the compression device of the embodiment of the present application includes a box body 100, a cooling unit 300 and at least one compressor unit 200.

[0038] The top of the box 100 is provided with an air inlet 101 and an air outlet 102 located on one side of the air inlet 101. Exemplarily, the box 100 may be in the shape of a cuboid, the air outlet 102 may be provided in the middle of the top surface of the box 100, the top surface of the box 100 may be provided with an air inlet 101 near one end of the box 100, and the air inlet 101 may be adjacent to the air outlet 102. Of course, the box 100 is not limited to the cuboid shape. In practical applications, the specific shape of the box 100 may be flexibly constructed according to actual needs. Alternatively or additionally, a mesh structure or a grille structure may be provided at the air inlet 101. Similarly, a mesh structure or a grille structure may also be provided at the air outlet 102.

[0039] The at least one compressor unit 200 is disposed in the housing 100, and the compressor unit 200 is used to compress gas. Alternatively or additionally, the gas may be air, or other gases such as nitrogen, hydrogen, water vapor, etc. Alternatively or additionally, the at least one compressor unit 200 may include one compressor unit 200, or may include multiple compressor units 200. For example, the compression device may include two compressor units 200, three compressor units 200, and the like.

[0040] The cooling unit 300 includes a cooling cabin 310, a fan assembly 320 and a plurality of coolers 330. The cooling cabin 310 is arranged in the housing 100 and below the air outlet 102. At least one side of the cabin wall of the cooling cabin 310 is formed by at least one of the plurality of coolers 330 arranged vertically, and at least part of the bottom wall of the cooling cabin 310 is formed by at least one of the plurality of coolers 330 arranged horizontally, and the plurality of coolers 330 are respectively connected to the compressor unit 200. The fan assembly 320 is arranged at the top wall of the cooling cabin 310 and is opposite to the air outlet 102. The fan assembly 320 is used to guide the airflow from the air inlet 101 into the housing 100 and flows through the plurality of coolers 330 to cool down the compressor unit 200.

[0041] The shape of the cooling chamber 310 can be flexibly selected according to actual needs, as long as it has a top wall, a bottom wall, and at least one side wall between the top wall and the bottom wall. For example, the cooling chamber 310 can be in a rectangular parallelepiped or a cube shape, and the rectangular parallelepiped or cube-shaped cooling chamber 310 can have a top wall, a bottom wall, and four side walls.

[0042] Alternatively or additionally, the cooling chamber 310 may have a side bulkhead formed by at least one cooler 330 arranged vertically. The cooling chamber 310 may also have multiple side bulkheads respectively formed by at least one cooler 330 arranged vertically. Exemplarily, the cooling chamber 310 may be in a rectangular parallelepiped shape, and the cooling chamber 310 may have four side bulkheads, one of the four side bulkheads of the cooling chamber 310 may be formed by at least one cooler 330 arranged vertically, and two, three or four of the four side bulkheads of the cooling chamber 310 may be formed by at least one cooler 330 arranged vertically.

[0043] Alternatively or additionally, the cooler 330 may have a long side and a short side, the long side of the cooler 330 may extend in the transverse direction, and the short side of the cooler 330 may extend in the vertical direction. Alternatively, the long side of the cooler 330 may also extend in the vertical direction, and the short side of the cooler 330 may extend in the transverse direction. For example, the cooler 330 may be in the shape of a rectangular parallelepiped, and the cooler 330 may have a first side, a second side, and a third side that are perpendicular to each other, the length of the first side may be greater than the length of the second side and the length of the third side, and the length of the third side may be less than the length of the first side and the length of the second side. The first side of the cooler 330 may be configured to extend in the transverse direction, and the second side of the cooler 330 may be configured to extend in the vertical direction. With respect to the bottom wall of the cooling chamber 310, in one example, the entire bottom wall of the cooling chamber 310 may be formed by the at least one cooler 330 arranged in the transverse direction. In another example, part of the bottom wall of the cooling chamber 310 may be formed by the at least one transversely arranged cooler 330, and the rest of the bottom wall of the cooling chamber 310 may be formed by other structures such as a beam or a plate-like structure. Alternatively or additionally, at least part of the bottom wall of the cooling chamber 310 may be formed by one transversely arranged cooler 330, or by a plurality of transversely arranged coolers 330 in parallel.

[0044] It is understandable that the coolers 330 here are all air-cooled coolers 330, and the air-cooled coolers 330 usually have a penetrating airflow channel. For example, the multiple coolers 330 can be finned coolers 330, and the finned coolers 330 usually have a fluid pipeline and fins that are heat-conductively connected to the fluid pipeline, and there are usually gaps between the fins for airflow to pass through. On this basis, the side bulkhead and the bottom wall of the cooling cabin 310 formed by the coolers 330 are both non-enclosed bulkhead structures, and the airflow can pass through the side bulkhead and the bottom wall of the cooling cabin 310.

[0045] Alternatively or additionally, the multiple coolers 330 may be connected in parallel or in series. The multiple coolers 330 may be used to cool the same type of fluid of the compressor unit 200, or may be used to cool different fluids of the compressor 210. For example, the multiple coolers 330 may be connected in series to perform multi-stage cooling on the high-temperature compressed gas formed by the compressor 210. For another example, when the multiple compressor units 200 are used to compress different fluids, the multiple coolers 330 may be used to cool different types of fluids. For another example, when the same compressor unit 200 is capable of producing different types of fluids, the different types of fluids produced by the same compressor unit 200 may also be cooled separately by multiple coolers 330.

[0046] Alternatively or additionally, the top wall of the cooling chamber 310 may be formed by the fan assembly 320, or the fan assembly 320 may be embedded in the top wall of the cooling chamber 310. For example, one or more through-going mounting holes may be provided in the top wall of the cooling chamber 310. The fan assembly 320 may include one or more fans, which may be installed in the mounting holes.

[0047] like Figure 4 As shown, in the actual operation process of the compression device, the fan assembly 320 guides the air flow from the air inlet 101 into the box 100, and a part of the air flow passes through the cooler 330 arranged vertically and enters the cooling chamber 310. Another part of the air flow goes around to the bottom of the cooling chamber 310 through the gap between the devices, and passes through the cooler 330 arranged horizontally and enters the cooling chamber 310. The air flow in the cooling chamber 310 generally flows vertically upward, and to a certain extent, it can achieve the purpose of secondary cooling of the cooler 330 arranged vertically. Afterwards, it flows out of the box 100 through the air outlet 102.

[0048] The compression device of the embodiment of the present application can, on the one hand, make the cooling unit 300 compact and small in size, which is conducive to miniaturization of the compression device. On the other hand, it can make the cooling unit 300 have a higher heat dissipation efficiency, and have a relatively larger heat dissipation power than similar products of the same size, while better reducing the temperature in the entire box 100. On the other hand, since the air inlet 101 and the air outlet 102 are concentrated on the top of the box 100, it is conducive to reducing noise. Figure 4 As shown, the compression device may further include a first air guide cover 105 and a second air guide cover 106. The first air guide cover 105 is arranged at the top of the air inlet 101, and the second air guide cover 106 is arranged at the top of the air outlet 102. The first air guide cover 105 is not only conducive to the smooth flow of the air into the box body 100 and out of the box body 100, so as to improve the heat dissipation efficiency. Moreover, it is conducive to further reducing the noise level of the compression device.

[0049] In some embodiments, a side bulkhead of the cooling chamber 310 near the air inlet 101 is formed by at least one of the multiple coolers 330 arranged vertically. In this way, after the airflow flows into the box 100 from the air inlet 101, at least a part of the airflow can first pass through at least one of the coolers 330 arranged vertically forming the side bulkhead in a direction nearly perpendicular to the side bulkhead, and another part of the airflow goes around to the bottom of the cooling chamber 310 through the gap between the devices, passes through the cooler 330 arranged horizontally and enters the cooling chamber 310, and cools the at least one cooler 330 arranged vertically again while discharging the airflow upward, forming secondary cooling, which is beneficial to improving the heat dissipation efficiency of the cooler 330, and further beneficial to improving the heat dissipation power of the cooling unit 300.

[0050] For example, the cooling cabin 310 may be in a rectangular parallelepiped shape, and the cooling cabin 310 may have four side bulkheads. Among the four side bulkheads of the cooling cabin 310, one side bulkhead close to the air inlet 101 may be formed by one or more coolers 330, and the other three side bulkheads of the cooling cabin 310 may be formed by a plate-like structure. Of course, one or more of the other three side bulkheads of the cooling cabin 310 may also be formed by the cooler 330.

[0051] In some embodiments, the compressor unit 200 has an air outlet, a lubricating medium inlet, and a lubricating medium outlet. The plurality of coolers 330 include at least one first cooler 331 and at least one second cooler 332. The at least one first cooler 331 is connected to the air outlet of the compressor unit 200. The at least one second cooler 332 is respectively connected to the lubricating medium inlet and the lubricating medium outlet of the compressor unit 200.

[0052] Alternatively or additionally, the compressor unit 200 is an oil-lubricated compressor unit, a water-lubricated compressor unit or a dry compressor unit. Correspondingly, the lubricating medium may include but is not limited to lubricating oil or water, etc. On this basis, the cooling unit 300 not only needs to cool the high-temperature compressed gas output by the compressor unit 200, but also needs to cool the lubricating medium of the compressor unit 200, and then transport the cooled lubricating medium back to the compressor unit 200.

[0053] Alternatively or additionally, the at least one first cooler 331 may include one first cooler 331, or may include a plurality of first coolers 331. For example, the high-temperature compressed gas output by the compressor unit 200 may be cooled by the first cooler 331, or the high-temperature compressed gas output by the compressor unit 200 may be cooled by a plurality of first coolers 331 connected in series or in parallel to reduce the temperature of the compressed gas.

[0054] Alternatively or additionally, the at least one second cooler 332 may include one second cooler 332, or may include a plurality of second coolers 332. For example, the lubricating medium output by the compressor unit 200 may be cooled by the second cooler 332, or the lubricating medium output by the compressor 210 may be cooled by a plurality of second coolers 332 connected in series or in parallel, so as to improve cooling efficiency.

[0055] In some embodiments, the side wall of the cooling cabin 310 near the air inlet 101 is formed by at least one first cooler 331 arranged vertically, and at least part of the bottom wall of the cooling cabin 310 is formed by at least one second cooler 332 arranged horizontally. In this way, it is helpful to improve the heat dissipation efficiency of the compressed gas. Of course, the at least one first cooler 331 can also be configured to be arranged horizontally to form at least part of the bottom wall of the cooling cabin 310, and the at least one second cooler 332 can also be configured to be arranged vertically to form a side wall of the cooling cabin 310.

[0056] In some embodiments, the compressor unit 200 includes a compressor 210 and a gas-liquid separator 220 connected to the compressor 210, and the gas outlet of the gas-liquid separator 220 is connected to at least one first cooler 331. The at least one second cooler 332 can be connected to the lubricating medium outlet of the gas-liquid separator 220 and the lubricating medium inlet of the compressor 210, respectively.

[0057] Specifically, the air outlet of the compressor 210 can be connected to the air inlet of the gas-liquid separator 220. The compressor 210 compresses the gas into high-temperature compressed gas, and delivers it to the gas-liquid separator 220 through the air outlet of the compressor 210. The gas-liquid separator 220 performs gas-liquid separation on the lubricating medium and the high-temperature compressed gas. The gas-liquid separator 220 delivers the high-temperature compressed gas to the at least one first cooler 311 through its air outlet for cooling. After the at least one first cooler 311 cools the compressed gas, the cooled compressed gas can be delivered to the gas supply pipeline for subsequent use by the user. The gas-liquid separator 220 delivers the lubricating medium to the at least one second cooler 332 through its lubricating medium outlet for cooling. After the at least second cooler 332 cools the lubricating medium, the lubricating medium can be delivered back to the lubricating medium inlet of the compressor 210 for continuous lubrication of the compressor 210.

[0058] Alternatively or additionally, the compressor 210 is an oil-lubricated compressor, a water-lubricated compressor or a dry compressor. For example, the compressor 210 may be an oil-injected screw compressor, and the corresponding gas-liquid separator 220 may be an oil-gas separator. For another example, the compressor may be a water-lubricated screw compressor, and the corresponding gas-liquid separator 220 may be a water-gas separator. Obviously, the compressor 210 is not limited to an oil-injected screw compressor, but may also include other types of compressors. The gas-liquid separator 220 is also not limited to an oil-gas separator and a water-gas separator. The gas-liquid separator 220 may also include a separator capable of separating other lubricating media and compressed gas.

[0059] In some embodiments, the gas-liquid separator 220 is disposed below the air inlet 101, and the compressor 210 is disposed below the cooling compartment 310. A first gap 251 is provided between the gas-liquid separator 220 and a side wall of the cooling compartment 310, and a second gap 252 is provided between the compressor 210 and the bottom wall of the cooling compartment 310. The first gap 251 and the second gap 252 are interconnected to form a heat dissipation channel 253 that is connected to the air inlet 101 and the cooling compartment 310. In this way, after the airflow flows into the box 100 through the air inlet 101, it can smoothly flow into the cooling compartment 310 along the heat dissipation channel 253, which is conducive to improving the heat dissipation efficiency and heat dissipation power of the cooling unit 300.

[0060] Alternatively or additionally, the compressor 210 may include a compression host and a drive motor connected to the compression host. The gas-liquid separator 220, the compression host and the drive motor may be arranged in a first direction (eg Figure 3 In this way, the compressor main unit and the drive motor are located below the heat dissipation channel 253. When the airflow flows through the heat dissipation channel 253, it can also take away the heat generated by the compressor main unit and the drive motor, and while cooling the compressed air and the lubricating medium, it also takes away most of the heat in the box.

[0061] It should be noted that although a heat dissipation channel 253 is provided between the cooling chamber 310 and the compressor 210 and the gas-liquid separator 220, Figure 4 As shown, when the compression device is actually running, the airflow has multiple flow paths in the box body 100 and is not limited to flowing along the heat dissipation channel 253.

[0062] In some embodiments, the at least one compressor unit 200 may include multiple compressor units 200. The at least one first cooler 331 includes a first cooler 331, the first cooler 331 has multiple air inlets, and the multiple air inlets of the first cooler 331 are respectively connected to the air outlets of the multiple compressor units 200. The at least one second cooler 332 includes multiple second coolers 332, and the multiple second coolers 332 are respectively connected to the lubricating medium inlet and the lubricating medium outlet of the multiple compressor units 200. In this way, the high-temperature compressed gas formed by the multiple compressor units 200 is not only cooled in the first cooler 331, but also mixed in the first cooler 331, which is conducive to maintaining the outlet pressure and outlet temperature stable.

[0063] For example, Figure 5As shown, the plurality of compressor units 200 include a first compressor unit 230 and a second compressor unit 240. The first cooler 331 has a first air inlet 333, a second air inlet 334 and an air outlet, the first air inlet 333 is connected to the air outlet of the first compressor unit 230, the second air inlet 334 is connected to the air outlet of the second compressor unit 240, and the air outlet of the first cooler 331 is connected to the air supply pipeline. The plurality of second coolers 332 include at least two second coolers 332, one second cooler 332 is connected to the lubricating medium inlet and the lubricating medium outlet of the first compressor unit 230, and the other second cooler 332 is connected to the lubricating medium inlet and the lubricating medium outlet of the second compressor unit 240.
