[0003] Compressors are used to compress gases, and the compressors usually need to be equipped with a cooling system to assist the operation of the compressor.

[0034] The present embodiment provides a compression device utilizing air cooling for heat dissipation. Referring to FIGS. 1-4, the compression device of the present embodiment includes a cabinet 100, a cooling unit 300, and at least one compressor unit 200.

[0035] The top of the box 100 is provided with an air inlet 101 and an air outlet 102 located at one side of the air inlet 101. Exemplarily, the box 100 can be cuboid, the top surface of the box 100 can be provided with the air outlet 102, the top surface of the box 100 can be provided with the air inlet 101 near one end of the box 100, and the air inlet 101 can be adjacent to the air outlet 102. Of course, the box 100 is not limited to a cuboid shape, and the specific shape of the box 100 can be flexibly constructed according to actual needs in actual application. In some examples, the air inlet 101 can be provided with a mesh structure or a grid structure. Similarly, the air outlet 102 can also be provided with a mesh structure or a grid structure.

[0036] The at least one compressor set 200 is arranged in the box 100, and the compressor set 200 is used for compressing gas. In some examples, the gas can be air, or other gases such as nitrogen, hydrogen, water vapor, etc. In some examples, the at least one compressor set 200 can include one compressor set 200, or can include a plurality of compressor sets 200. For example, the compression device can include two compressor sets 200, three compressor sets 200, etc.

[0037] The cooling set 300 includes a cooling cabin 310, a fan assembly 320, and a plurality of coolers 330. The cooling cabin 310 is arranged in the box 100 and located below the air outlet 102. At least one side wall of the cooling cabin 310 is formed by at least one of the plurality of coolers 330 arranged vertically, 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 with the compressor set 200. The fan assembly 320 is arranged at the top wall of the cooling cabin 310 and opposite to the air outlet 102. The fan assembly 320 is used for guiding the airflow to flow into the box 100 from the air inlet 101, and flow through the plurality of coolers 330 to cool and cool the compressor set 200.

[0038] The shape of the cooling cabin 310 can be flexibly selected and constructed 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 cabin 310 can be cuboid or square, and the cuboid or square cooling cabin 310 can have a top wall, a bottom wall, and four side walls.

[0039] In some examples, the cooling cabin 310 can have one side wall formed by at least one vertically arranged cooler 330. The cooling cabin 310 can also have multiple side walls each formed by at least one vertically arranged cooler 330. For example, the cooling cabin 310 can be cuboid-shaped, the cooling cabin 310 can have four side walls, one of the four side walls of the cooling cabin 310 can be formed by at least one vertically arranged cooler 330, and two, three or all of the four side walls of the cooling cabin 310 can be formed by at least one vertically arranged cooler 330.

[0040] In some examples, the cooler 330 can have a long side and a short side, the long side of the cooler 330 can extend horizontally, and the short side of the cooler 330 can extend vertically. Alternatively, the long side of the cooler 330 can extend vertically, and the short side of the cooler 330 can extend horizontally. For example, the cooler 330 can be cuboid-shaped, the cooler 330 can have a first side, a second side and a third side perpendicular to each other, the length of the first side can be greater than the length of the second side and the length of the third side, and the length of the third side can be less than the length of the first side and the length of the second side. The first side of the cooler 330 can be configured to extend horizontally, and the second side of the cooler 330 can be configured to extend vertically. With respect to the bottom wall of the cooling cabin 310, in one example, the entire bottom wall of the cooling cabin 310 can be formed by the at least one horizontally arranged cooler 330. In another example, part of the bottom wall of the cooling cabin 310 can be formed by the at least one horizontally arranged cooler 330, and the remaining part of the bottom wall of the cooling cabin 310 can be formed by other structures such as beams or plates. In some examples, at least part of the bottom wall of the cooling cabin 310 can be formed by one horizontally arranged cooler 330, and can also be formed by multiple horizontally arranged coolers 330 arranged side by side.

[0041] It can be understood that the coolers 330 herein are all air-cooled coolers 330, which generally have air flow channels therethrough. For example, the coolers 330 can be finned coolers 330, which generally have fluid ducts and fins in heat-conducting connection with the fluid ducts, and gaps between the fins for air flow to pass through. On this basis, the side wall and the bottom wall of the cooling cabin 310 formed by the coolers 330 are both non-enclosed wall structures, and air flow can pass through the side wall and the bottom wall of the cooling cabin 310.

[0042] In some examples, the plurality of coolers 330 can be connected in parallel or in series. The plurality of coolers 330 can be used to cool the same type of fluid of the compressor set 200 or different types of fluid of the compressor set 200 respectively. For example, the plurality of coolers 330 can be connected in series to cool the high-temperature compressed gas of the compressor 210 in multiple stages. Also for example, when the plurality of compressor sets 200 are used to compress different types of fluid respectively, the plurality of coolers 330 can be used to cool the different types of fluid respectively. Also for example, when the same compressor set 200 is capable of producing different types of fluid, the plurality of coolers 330 can be used to cool the different types of fluid produced by the same compressor set 200 respectively.

[0043] In some examples, the top wall of the cooling cabin 310 can be formed by the fan assembly 320 or the fan assembly 320 can be embedded in the top wall of the cooling cabin 310. For example, the top wall of the cooling cabin 310 can be provided with one or more mounting holes. The fan assembly 320 can include one or more fans which can be mounted in the mounting holes.

[0044] As shown in FIG. 4, in actual operation of the compression device, the air flow is guided by the fan assembly 320 from the air inlet 101 into the cabinet 100. Part of the air flow passes through the vertically arranged coolers 330 into the cooling cabin 310. Another part of the air flow bypasses the cooling cabin 310 through the gap between the devices and reaches the bottom of the cooling cabin 310, and then passes through the horizontally arranged coolers 330 into the cooling cabin 310. The air flow in the cooling cabin 310 flows upward along the vertical direction, which can achieve the purpose of secondary cooling of the vertically arranged coolers 330 to a certain extent. Then, the air flow flows out of the cabinet 100 through the air outlet 102.

[0045] The compression device of the embodiment of the present application can achieve the following purposes. On the one hand, the structure of the cooling unit 300 is compact and small in size, which is conducive to miniaturization of the compression device. On the other hand, the cooling unit 300 has high heat dissipation efficiency, and has relatively large heat dissipation power under the same size compared with similar products, and can better reduce the temperature in the entire cabinet 100. On the other hand, the air inlets 101 and the air outlets 102 are arranged at the top of the cabinet 100, which is conducive to reducing noise. In combination with FIG. 4, the compression device can 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 arranged to facilitate smooth air flow into and out of the cabinet 100, thereby improving heat dissipation efficiency. Moreover, the first air guide cover 105 is arranged to further reduce the noise level of the compression device.

[0046] In some embodiments, the side wall of the cooling chamber 310 near the air inlet 101 is formed by at least one of the vertically arranged coolers 330. In this way, after the air flow enters the cabinet 100 from the air inlet 101, at least a portion of the air flow can first pass through the at least one vertically arranged cooler 330 forming the side wall in a direction approximately perpendicular to the side wall, and another portion of the air flow can bypass the at least one vertically arranged cooler 330 through the gap between the devices to the bottom of the cooling chamber 310, pass through the horizontally arranged cooler 330 into the cooling chamber 310, and cool the at least one vertically arranged cooler 330 again while discharging the air flow upward, forming secondary cooling, which is beneficial to improve the heat dissipation efficiency of the cooler 330, and in turn, is beneficial to improve the heat dissipation power of the cooling unit 300.

[0047] For example, the cooling chamber 310 can be a cuboid, and the cooling chamber 310 can have four side walls. The side wall of the cooling chamber 310 near the air inlet 101 can be formed by one or more coolers 330, and the remaining three side walls of the cooling chamber 310 can be formed by plate structures. Of course, one or more of the remaining three side walls of the cooling chamber 310 can also be formed by coolers 330.

[0048] 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 includes 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.

[0049] In some examples, the compressor unit 200 is an oil-lubricated compressor unit, a water-lubricated compressor unit, or a dry compressor unit. Correspondingly, the lubricating medium can 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 deliver the cooled lubricating medium back to the compressor unit 200.

[0050] In some examples, the at least one first cooler 331 can include one first cooler 331 or a plurality of first coolers 331. For example, the high-temperature compressed gas output by the compressor unit 200 can be cooled by one first cooler 331, or the high-temperature compressed gas output by the compressor unit 200 can be cooled by a plurality of first coolers 331 connected in series or in parallel to reduce the temperature of the compressed gas.

[0051] In some examples, the at least one second cooler 332 can include one second cooler 332, or can include a plurality of second coolers 332. For example, the lubricating medium outputted by the compressor set 200 can be cooled by one second cooler 332, or can be cooled by a plurality of second coolers 332 connected in series or in parallel to improve the cooling efficiency.

[0052] In some examples, the side wall of the cooling cabin 310 close to the air inlet 101 is formed by the at least one first cooler 331 arranged vertically, and the at least part of the bottom wall of the cooling cabin 310 is formed by the at least one second cooler 332 arranged horizontally. In this way, the heat dissipation efficiency of the compressed gas is improved. Of course, the at least one first cooler 331 can also be arranged horizontally to form the at least part of the bottom wall of the cooling cabin 310, and the at least one second cooler 332 can also be arranged vertically to form the side wall of the cooling cabin 310.

[0053] In some examples, the compressor set 200 includes the compressor 210 and the gas-liquid separator 220 connected to the compressor 210, and the gas outlet of the gas-liquid separator 220 is connected to the at least one first cooler 331. The at least one second cooler 332 can be respectively connected to the lubricating medium outlet of the gas-liquid separator 220 and the lubricating medium inlet of the compressor 210.

[0054] Specifically, the gas outlet of the compressor 210 can be connected to the gas inlet of the gas-liquid separator 220. The compressor 210 compresses the gas into high-temperature compressed gas, which is delivered to the gas-liquid separator 220 through the gas outlet of the compressor 210. The gas-liquid separator 220 separates 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 the gas outlet thereof, and the at least one first cooler 311 cools and lowers the temperature of the compressed gas, and then delivers the cooled compressed gas 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 the lubricating medium outlet thereof, and the at least one second cooler 332 cools and lowers the temperature of the lubricating medium, and then delivers the lubricating medium back to the lubricating medium inlet of the compressor 210 for continuously lubricating the compressor 210.

[0055] In some examples, the compressor 210 is an oil-lubricated compressor, a water-lubricated compressor, or a dry compressor, for example, the compressor 210 can be an oil-injected screw compressor, and the corresponding gas-liquid separator 220 can be an oil-gas separator. For another example, the compressor can be a water-lubricated screw compressor, and the corresponding gas-liquid separator 220 can be a water-gas separator. Obviously, the compressor 210 is not limited to an oil-injected screw compressor, but can 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 can also include a separator capable of separating other lubricating media and compressed gas.

[0056] In some embodiments, the gas-liquid separator 220 is arranged below the air inlet 101, and the compressor 210 is arranged below the cooling cabin 310. The gas-liquid separator 220 and one side wall of the cooling cabin 310 have a first gap 251, and the compressor 210 and the bottom wall of the cooling cabin 310 have a second gap 252. The first gap 251 and the second gap 252 are in communication with each other to form a heat dissipation channel 253 in communication with the air inlet 101 and the cooling cabin 310. In this way, after the airflow flows into the cabinet 100 through the air inlet 101, it can smoothly flow into the cooling cabin 310 along the heat dissipation channel 253, which is beneficial to improve the heat dissipation efficiency and heat dissipation power of the cooling unit 300.

[0057] In some examples, the compressor 210 can include a compression host and a drive motor in driving connection with the compression host. The gas-liquid separator 220, the compression host, and the drive motor can be arranged in sequence along a first direction (for example, the left-right direction in FIG. 3). In this way, the compression host and the drive motor are located below the heat dissipation channel 253, and the airflow flowing through the heat dissipation channel 253 can also carry away the heat generated by the compression host and the drive motor, thereby cooling the compressed air and the lubricating medium while carrying away most of the heat in the cabinet.

[0058] It should be noted that although the heat dissipation channel 253 is arranged between the cooling cabin 310 and the compressor 210 and the gas-liquid separator 220, as shown in FIG. 4, when the compression device is actually running, the airflow has multiple flow paths in the cabinet 100, and is not limited to flowing along the heat dissipation channel 253.

[0059] In some embodiments, the at least one compressor group 200 can include a plurality of compressor groups 200. The at least one first cooler 331 includes a first cooler 331 having a plurality of gas inlets, the plurality of gas inlets of the first cooler 331 being respectively connected to the gas outlets of the plurality of compressor groups 200. The at least one second cooler 332 includes a plurality of second coolers 332, the plurality of second coolers 332 being respectively connected to the lubricating medium inlets and the lubricating medium outlets of the plurality of compressor groups 200. In this way, the high-temperature compressed gas formed by the plurality of compressor groups 200 is not only cooled in the first cooler 331, but also mixed in the first cooler 331, which is conducive to keeping the gas outlet pressure and the gas outlet temperature stable.

[0060] Exemplarily, as shown in FIG. 5, the plurality of compressor groups 200 includes a first compressor group 230 and a second compressor group 240. The first cooler 331 has a first gas inlet 333, a second gas inlet 334, and a gas outlet, the first gas inlet 333 being connected to the gas outlet of the first compressor group 230, the second gas inlet 334 being connected to the gas outlet of the second compressor group 240, and the gas outlet of the first cooler 331 being connected to the gas supply pipeline. The plurality of second coolers 332 includes at least two second coolers 332, one of the second coolers 332 being connected to the lubricating medium inlet and the lubricating medium outlet of the first compressor group 230, and the other of the second coolers 332 being connected to the lubricating medium inlet and the lubricating medium outlet of the second compressor group 240.

[0061] In some examples, the at least two second coolers 332 can include two second coolers 332, or three, four, or more second coolers 332. For example, the cooling unit 300 can include two second coolers 332, the first compressor group 230 being connected to one of the second coolers 332, and the second compressor group 240 being connected to the other of the second coolers 332. For another example, the cooling unit 300 can include four second coolers 332, two of the second coolers 332 being connected in series, the other two of the second coolers 332 being connected in series, the first compressor group 230 being connected to one set of the two second coolers 332 connected in series, and the second compressor group 240 being connected to the other set of the two second coolers 332 connected in series, to form two-stage cooling.

[0062] In some examples, the plurality of compressor groups 200 can be arranged in a second direction (e.g., the up-down direction in FIG. 2) perpendicular to the first direction.
