Detailed Implementation

[0017] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0018] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects.

[0019] As mentioned earlier, compressors generate a significant amount of heat during operation, typically requiring multiple air inlets and outlets within the compressor casing, and a fan to guide airflow for heat dissipation. The design of the compressor's heat dissipation channels directly impacts its heat dissipation efficiency, structural strength, and noise level.

[0020] In traditional compressors, the casing typically uses a closed base (i.e., no intake structure is installed on the base), with intake holes on the side wall of the casing. Although the base has high structural strength, the cooling airflow needs to pass through multiple turns and changes of direction, resulting in relatively high airflow resistance and relatively poor heat dissipation. Therefore, traditional compressors often struggle to balance cooling efficiency, structural strength, and noise levels.

[0021] To address, or at least partially address, the aforementioned problems or other potential problems existing in conventional technologies, embodiments of this disclosure provide a compressor. The compressor includes a housing, a compressor unit, and a cooling unit. The housing has an internal cavity and includes a base. The base includes an open area and a non-open area. The open area has a plurality of first vent holes, and the internal cavity communicates with the outside of the housing through the plurality of first vent holes. The compressor unit includes at least a compressor main unit, a drive motor, and an oil-gas separator. The compressor main unit is drive-connected to the drive motor, and the exhaust port of the compressor main unit is connected to the oil-gas separator. The compressor main unit, drive motor, and oil-gas separator are deployed in the non-open area. The cooling unit is suspended at the top of the internal cavity and includes a fan opposite to at least a portion of the open area and at least one cooler opposite to the fan. The at least one cooler is connected to the oil-gas separator and is adapted to cool the lubricating oil and / or compressed gas output from the oil-gas separator.

[0022] In the embodiments of this disclosure, the base includes an open area and a non-open area. Components such as the compressor main unit, drive motor, and oil-gas separator are deployed in the non-open area, not in the open area. This approach ensures the structural strength of the base and the stability of the compressor unit, balances the compressor's noise level to a certain extent, and avoids obstructing airflow, thus reducing airflow resistance. Furthermore, since the fan is opposite to at least part of the open area, it reduces airflow deflections and changes in path, thereby improving heat dissipation efficiency.

[0023] Figure 1 and Figure 2 The following are perspective views of compressors from different perspectives, representing some embodiments of the present disclosure. Figure 3 and Figure 4 Perspective views of partial structures of compressors according to some embodiments of this disclosure are shown from different perspectives. Specifically, to facilitate the presentation of the internal mechanism of the compressor, in Figure 3 and Figure 4 The details of the shell structure, such as the sidewalls, are omitted. See also Figures 1 to 4 As shown, the compressor of an embodiment of this disclosure includes a housing 100, a compressor unit 200, and a cooling unit 300. These components will be described below with reference to the accompanying drawings and examples.

[0024] The housing 100 has an interior cavity 101 and includes a base 110. In some examples, the housing 100 may also include a top wall 145 opposite to the base 110 and a plurality of side walls, the base 110, top wall 145, and the plurality of side walls together defining the interior cavity 101 of the housing 100. As an example, combined with Figure 1 and Figure 2 As shown, the housing 100 may be cuboid or approximately cuboid in shape. The housing 100 may include a cuboid-shaped top wall 145 and a base 110, as well as a first side wall 141, a second side wall 142, a third side wall 143, and a fourth side wall 144. Of course, the above-described housing 100 is merely exemplary, and the housing 100 may be constructed into any other suitable shape according to actual needs.

[0025] Figure 5 A perspective view of a portion of the structure of the base 110 according to some embodiments of the present disclosure is shown. Figure 6 A perspective view of a base 110 according to some embodiments of the present disclosure is shown. Relative to Figure 6 , Figure 5 Filter material layer 121 has been removed. See also Figures 3 to 6 As shown, the base 110 may include an open area 114 and a non-open area 115. The open area 114 is provided with a plurality of first vent holes 116, and the inner cavity 101 communicates with the outside of the housing 100 through the plurality of first vent holes 116. Airflow can flow into the inner cavity 101 through the plurality of first vent holes 116 to dissipate heat from components such as the compressor unit 200 and the cooling unit 300, and to provide air intake for the compressor unit 200. As an example, combined with Figure 5 As shown, the plurality of first vent holes 116 can be rectangular or square, and the plurality of first vent holes 116 can be regularly arranged along the length and / or width direction of the base 110. The non-perforated area 115 can be understood as an area without holes or openings for airflow. However, the non-perforated area 115 can be provided with connecting holes such as screw holes or bolt holes, and should not be construed as the non-perforated area 115 being unable to provide any hole structures.

[0026] In some embodiments, combined with Figure 5 As shown, the top surface of the base 110 can be rectangular, and both the perforated area 114 and the non-perforated area 115 are L-shaped. This creates an approximately "Z"-shaped boundary between the perforated area 114 and the non-perforated area 115, with intersecting areas between them, which helps improve the structural strength of the base 110. Of course, the perforated area 114 and the non-perforated area 115 can also be any other suitable shape. The embodiments of this disclosure do not limit this.

[0027] In some embodiments, combined with Figure 5 and Figure 6 As shown, at least a portion of the opening area 114 is covered with a filter material layer 121 for filtering the airflow from the bottom intake. A cover 122 can be disposed above the opening area 114, and the cover 122 has multiple second vent holes 123. A receiving space can be defined between the cover 122 and the opening area 114. The filter material layer 121 can be disposed within the receiving space, in which case the filter material layer 121 can selectively cover part or all of the opening area 114. During compressor operation, the airflow enters the receiving space through the first vent hole 116, is filtered by the filter material layer 121, and then enters the inner cavity 101 through the second vent holes 123. In this way, the filter material layer 121 can be used to filter the intake airflow, which helps to improve the cleanliness of the intake air. The cover 122 can fix and protect the filter material layer 121, which helps to extend the replacement cycle of the filter material layer 121. Moreover, the filter material layer 121 can absorb or block noise, which helps to reduce the noise level of the compressor.

[0028] In some examples, an opening 124 communicating with the accommodating space may be provided between the housing 122 and the base 110, and the opening 124 may be configured to facilitate replacement of the filter material layer 121. As an example, combined with... Figure 5 and Figure 6 As shown, the opening area 114 can be L-shaped. The cross-section of the cover 122 can also be L-shaped. Multiple second vents 123 corresponding one-to-one with the multiple first vents 116 can be provided on the cover 122 to reduce airflow resistance. An opening 124 can be defined between one side edge of the cover 122 and the base 110. The filter material layer 121 can be replaced through this opening 124 to improve the ease of replacement. The filter material layer 121 can include any suitable material layer that filters airflow. Examples of the filter material layer 121 may include, but are not limited to, filter cotton layers, activated carbon layers, etc. The embodiments disclosed herein are not limited to this.

[0029] It should also be noted that the cover 122 is not mandatory. In practical applications, a filter material layer 121 can be provided separately, and at least a portion of the opening area 114 can be covered by the filter material layer 121. This can also achieve the purpose of filtering gas and reducing noise.

[0030] In some embodiments, combined with Figure 5 and Figure 6As shown, the base 110 may include a plate-like structure 111, a first support portion 112, and a second support portion 113. An open area 114 and a non-open area 115 may be deployed on the plate-like structure 111. The first support portion 112 and the second support portion 113 may be disposed below the plate-like structure 111. The first support portion 112 may be connected to one end of the plate-like structure 111, and the second support portion 113 may be connected to the other end of the plate-like structure 111. An air intake channel 117 communicating with a plurality of first vent holes 116 is defined between the first support portion 112, the second support portion 113, and the plate-like structure 111. Thus, when the base 110 is placed on a supporting surface such as the ground, the first vent holes 116 can be prevented from being blocked, which helps to reduce air intake resistance and ensures heat dissipation efficiency.

[0031] As an example, combined Figure 5 and Figure 6 As shown, the plate-like structure 111 may include a rectangular plate arranged horizontally, and the first support portion 112 and the second support portion 113 may each include a rectangular plate arranged vertically. The width of the first support portion 112 and the second support portion 113 may be the same as the width of the plate-like structure 111. For example, the first support portion 112 and the second support portion 113 may be formed by bending the two ends of the plate-like structure 111. This reduces the difficulty of processing.

[0032] In some examples, combined Figures 3 to 5 As shown, the first support portion 112 is provided with at least one first through hole 118, and the second support portion 113 is provided with at least one second through hole 119. For example, the first support portion 112 may be provided with two rectangular first through holes 118. The second support portion 113 may be provided with two rectangular second through holes 119. This can further reduce intake resistance and is beneficial to reducing the weight of the housing 100. It should be understood that the shape and number of the above-mentioned first through holes 118 and second through holes 119 are exemplary, and other arbitrarily appropriate shapes and numbers can be selected according to actual needs. The embodiments of this disclosure are not limited in this respect.

[0033] In some embodiments, the compressor unit 200 may include a compressor main unit 210, a drive motor 220, and an oil-gas separator 230. The compressor main unit 210 is drive-connected to the drive motor 220, and the exhaust port of the compressor main unit 210 is connected to the oil-gas separator 230. The compressor main unit 210, the drive motor 220, and the oil-gas separator 230 are deployed in a non-perforated area 115. The cooling unit 300 may be suspended on top of the inner cavity 101. The cooling unit 300 includes a fan 310 opposite to at least a portion of the perforated area 114 and at least one cooler 320 opposite to the fan 310. The at least one cooler 320 is connected to the oil-gas separator 230 and is adapted to cool the lubricating oil and / or compressed gas output from the oil-gas separator 230.

[0034] In actual operation, the drive motor 220 drives the compressor main unit 210 to operate, and the compressor main unit 210 compresses the gas. The compressor main unit 210 discharges the mixture of compressed gas and lubricating oil into the oil-gas separator 230, where the oil-gas mixture is separated. Afterwards, the lubricating oil and / or compressed gas discharged from the oil-gas separator 230 can be cooled using at least one cooler 320. The lubricating oil can flow back to the compressor main unit 210, and the compressed gas can be discharged externally.

[0035] As an example, the compressor main unit 210 and drive motor 220 can be arranged along the length of the base 110, and the oil-gas separator 230 can be deployed on one side of the compressor main unit 210. This improves the regularity of the compressor unit 200's layout and shortens the pipeline length, thus simplifying the pipeline structure. Of course, in practical applications, the compressor main unit 210, drive motor 220, and oil-gas separator 230 can also adopt any other suitable arrangement, and the embodiments of this disclosure do not limit this.

[0036] In some examples, combined Figures 1 to 4 As shown, the housing 100 may be provided with a top wall 145, and the top wall 145 may be provided with an exhaust port 146. The cooling unit 300 may be located below and opposite the exhaust port 146 to facilitate airflow discharge. Alternatively, the cooling unit 300 may form at least part of the top wall of the housing 100. This simplifies the structure of the housing 100.

[0037] In some embodiments, the fan 310 can be selected as an intake fan or a blower fan according to user needs, and at least one cooler 320 can be disposed above or below the fan 310. Figures 3 to 4 As shown in the example, at least one cooler 320 is positioned above the fan 310.

[0038] In some embodiments, the at least one cooler 320 may include an aftercooler 321 and an oil cooler 322. The inlet of the aftercooler 321 may be connected to the outlet of the oil-gas separator 230. The aftercooler 321 can cool and lower the temperature of the compressed gas, thereby reducing the exhaust temperature. The inlet of the oil cooler 322 is connected to the outlet of the oil-gas separator 230, and the outlet of the oil cooler 322 is connected to the inlet of the compressor. The oil cooler 322 can cool and lower the temperature of the lubricating oil.

[0039] As an example, the cooling unit 300 may also include an air guide shroud 330, the bottom surface of which may have an air inlet, and a fan 310 may be deployed at the air inlet. The top of the air guide shroud 330 may have an open structure, and the aftercooler 321 and oil cooler 322 may be arranged side by side laterally above the air guide shroud 330. Thus, the fan 310 can guide airflow into the air guide shroud 330, and then evenly flow through the aftercooler 320 and oil cooler 322, which helps to improve heat dissipation efficiency.

[0040] In some embodiments, combined with Figure 3 and Figure 4 As shown, the compressor unit 200 may further include an oil separator 250. The outlet of the oil-gas separator 230 can be connected to the inlet of the oil separator 250, and the outlet of the oil separator 250 can be connected to the inlet of the aftercooler 321. The oil separator 250 can be suspended above the non-perforated area 115. The oil separator 250 can perform a second oil-gas separation on the compressed gas output from the oil-gas separator 230 to further filter out at least some impurities (such as water or lubricating oil) in the compressed gas, thereby improving the cleanliness of the compressed gas. Moreover, suspending the oil separator 250 above the non-perforated area 115 can prevent the oil separator 250 from obstructing airflow.

[0041] In some examples, the oil separator 250 can be suspended above the non-perforated area 115 via a pipe. This simplifies the internal structure of the compressor. Alternatively, a support for the oil separator 250 can be provided within the housing 100 to improve its stability. The embodiments of this disclosure do not limit this.

[0042] In some embodiments, the compressor unit 200 may further include an oil filter 240, the oil inlet of which may be connected to the oil outlet of the oil cooler 322, and the oil outlet of the oil filter 240 may be connected to the oil inlet of the compressor main unit 210. After being cooled, the lubricating oil is delivered to the oil filter 240, where at least some impurities are filtered out to improve the cleanliness of the lubricating oil. The lubricating oil is then supplied to the compressor main unit 210 for lubrication and cooling.

[0043] In some embodiments, the oil inlet and outlet of the oil filter 240 can be located at the bottom end of the oil filter 240. The oil inlet of the oil filter 240 can be connected to the oil cooler 322 via, for example, an oil inlet pipe, and the oil outlet of the oil filter 240 can be connected to the compressor main unit 210 via, for example, an oil outlet pipe. The top of the oil filter 240 can be inclined towards the side wall of the housing 100. This facilitates disassembly and assembly from the upper side of the oil filter 240, and allows the oil filter 240 to be removed along its inclined direction, thereby improving the convenience of inspection and maintenance of the oil filter 240.

[0044] In some embodiments, combined with Figure 4 As shown, the compressor unit 200 also includes an air filter 260, which can be connected to the air inlet of the compressor main unit 210. The air filter 260 filters the air entering the inner cavity 101 through the opening area 114 of the base 110 to remove at least some impurities. The filtered air flows into the compressor main unit 210. This improves the cleanliness of the air entering the compressor main unit 210. As an example, the air inlet of the compressor main unit 210 can be located at the top of the compressor main unit 210, and the air filter 260 can be positioned above the compressor main unit 210.

[0045] In some embodiments, combined with Figure 3 and Figure 4 As shown, the compressor may also include electrical equipment 400, which is electrically connected to drive motor 220 and / or fan 310. Examples of electrical equipment 400 may include, but are not limited to, frequency converters, starters, protectors, controllers, etc. Power can be supplied to drive motor 220 and / or fan 310 through electrical equipment 400.

[0046] The electrical device 400 can be suspended above the opening area 114, and there is a gap between the bottom end of the electrical device 400 and the opening area 114. This gap can be any size range. In this way, the electrical device 400 can be prevented from blocking the first vent 116, and the obstruction effect of the electrical device 400 on airflow can be reduced to a certain extent, which is beneficial to improving heat dissipation efficiency.

[0047] As an example, a bracket may be provided in the inner cavity 101 of the housing 100, and the electrical device 400 may be connected to the bracket. The bottom surface of the electrical device 400 may have a certain distance between it and the opening area 114. Of course, the electrical device 400 may also be directly connected to the housing 100 via a connector, and the embodiments of this disclosure do not limit this.

[0048] In some embodiments, continue to combine Figure 3 and Figure 4As shown, the electrical device 400 has heat dissipation holes on its top. A ventilation hole 131 is provided in the area of ​​the housing 100 opposite to the heat dissipation holes. The inner cavity 101 communicates with the outside of the housing 100 through the ventilation hole 131, mainly for dissipating heat from the electrical device 400 to the outside of the housing 100 even when the fan 310 is not running. A cooling fan can be installed inside the electrical device 400 to guide the cooling airflow inside the electrical device 400 out through the heat dissipation holes on the top of the electrical device 400. Then, the air can be discharged to the outside of the housing 100 through the ventilation hole 131. This method helps to ensure the heat dissipation efficiency of the electrical device 400.

[0049] As an example, combined Figure 1 and Figure 2 As shown, the top wall 145 and the fourth side wall 144 of the housing 100 can be connected by an inclined control panel 130. Electrical equipment 400 can be deployed below the control panel 130. Multiple strip-shaped ventilation holes 131 can be provided in the area of ​​the control panel 130 opposite to the electrical equipment 400.

[0050] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
