Description

Technical Field

[0001] This application relates to the field of air compressor heat dissipation technology, and particularly to an air compressor side opening cooling structure. Background Art

[0002] An air compressor is a device used to compress air, mainly providing compressed air with a certain pressure for refrigeration or equipment that requires a high-pressure gas source.

[0003] The main principle of existing air compressors is to first filter the external air, and then introduce the filtered air into the compressor 11 for compression. The compressed air will pass through the oil-gas separator 12 for oil-gas separation; since a large amount of heat is generated by the compressor 11 and some driving motors during the compression process, the temperature of the compressor 11 and the air will be relatively high. At this time, the compressed air will first pass through the cooler 13 for cooling and then be discharged and used for equipment that requires a gas source; at the same time, the separated oil will also pass through different coolers 13 for cooling and then be reused.

[0004] However, in actual use, especially in summer, the external sunlight irradiation will cause the temperature of components such as the compressor 11 to be relatively high, which is likely to cause the temperature of the oil to be too high. At this time, the power of the compressor will drop, affecting the use effect; to solve this problem, the compressor 11, the oil-gas separator 12, and the cooler 13 are often arranged in a box body 14 provided with a heat dissipation port to isolate the external sunlight irradiation. However, in this treatment method, a large amount of heat generated by the compressor 11 and the driving motor during use accumulates in the box body 14, and only dissipates heat through the heat dissipation port on the box body 14, and the heat dissipation efficiency is relatively low, which will cause the compression efficiency of the compressor 11 during use to be relatively low. Summary of the Invention

[0005] In order to improve the heat dissipation efficiency of the air compressor during use, this application provides an air compressor side opening cooling structure.

[0006] An air compressor side opening cooling structure provided by this application adopts the following technical solution:

[0007] An air compressor side opening cooling structure includes a box body. A plurality of first heat dissipation ports are opened on the side of the box body. A wind guide cover is fixedly connected inside the box body. A plurality of heat dissipation air ducts communicating with the inside of the wind guide cover are arranged inside the box body. The end of the heat dissipation air duct far from the wind guide cover communicates with the inside of the box body. The box body is provided with an air outlet communicating with the inside of the wind guide cover, and a heat dissipation component for flowing the internal air out through the air outlet is arranged inside the wind guide cover. Some of the first heat dissipation ports are arranged corresponding to the wind guide cover, and the cooler is arranged between the wind guide cover and the corresponding first heat dissipation port, and the opening area of the first heat dissipation port corresponding to the cooler is larger than the sum of the opening areas of other first heat dissipation ports.

[0008] By adopting the above technical solution, during use, the compressor will generate relatively more heat, and at the same time, there will be evaporation of some oil. At this time, the heat dissipation component will draw the hot air in the box into the air guide cover through the heat dissipation air duct and discharge it through the air outlet. During this process, since the air guide cover is arranged in close fit with the cooler, the cooler can also be used to cool the air guide cover, making full use of the power consumed by the air compressor itself to reduce the temperature of the discharged air and reduce the impact on the surrounding environmental temperature. A negative pressure will be formed in the box, and then the air outside will be drawn into the box through the first heat dissipation port. And some of the first heat dissipation ports are arranged corresponding to the cooler, which can synchronously reduce the temperature of the air entering the box, so as to utilize the power consumed by the air compressor itself to optimize the heat dissipation efficiency in the box, thereby optimizing the heat dissipation effect while increasing the utilization of the power consumed by the air compressor itself and increasing the energy utilization rate. In addition, since the opening area of the first heat dissipation port corresponding to the cooler is larger than the sum of the opening areas of other first heat dissipation ports, the content of the cooled air in the air entering the box can be made relatively larger, thereby further optimizing the utilization of the cooling effect of the cooler.

[0009] Optionally, the distance between the first heat dissipation port corresponding to the cooler and the compressor is greater than the distance between other first heat dissipation ports and the compressor.

[0010] By adopting the above technical solution, the path of the cooled air flowing in the box can be made relatively longer, so as to fully mix with the hot air in the box, thereby reducing the air temperature in the box and achieving the purpose of optimizing the heat dissipation effect. At the same time, it can also reduce the influence on the cooled air entering from the first heat dissipation port corresponding to the cooler when the heat generated by the compressor causes the air to expand.

[0011] Optionally, a total air guide cover is arranged between the air guide cover and the cooler. The total air guide cover is bent and a total air duct is formed between it and the air guide cover. The heat dissipation air duct is communicated with the total air duct, and the cooler is fixedly connected to the total air guide cover. The total air guide cover is provided with an opening for communicating with the inside of the air guide cover.

[0012] By adopting the above technical solution, the total air duct formed by the total air guide cover can gather the discharged air together and then discharge it after being cooled by the cooler, so as to further optimize the cooling effect of the cooler.

[0013] Optionally, the total air guide cover is provided with at least one second heat dissipation port, and the opening area of the second heat dissipation port is smaller than that of the first heat dissipation port.

[0014] By adopting the above technical solution, the hot air can be drawn out at different positions in the box to form a turbulent flow and reduce the dead corners of being cooled.

[0015] Optionally, a plurality of second heat dissipation openings are provided and vertically distributed, and the height of the second heat dissipation openings is higher than the height of the compressor.

[0016] By adopting the above technical solution, according to the heat dissipation requirement, the second heat dissipation openings can be blocked to extract hot air at different heights, so as to promote the air flow in the box body. Therefore, according to the placement or installation of the equipment in the box body, the height of the air flow can be adjusted to perform adaptive and targeted heat dissipation.

[0017] Optionally, a plurality of third heat dissipation openings are provided in the heat dissipation air duct and horizontally distributed.

[0018] By adopting the above technical solution, by blocking the third heat dissipation openings, the hot air above the compressor can be extracted at different horizontal positions above the compressor, thereby reducing the possibility of hot air rising and accumulating at the top of the box body.

[0019] Optionally, the heat dissipation component includes a control member that drives air flow when rotating, a heat dissipation driving member for driving the control member to rotate, and a guiding cover for introducing air in the main air duct. The guiding cover is fixedly connected to the opening edge of the main air cover. The control member is fixedly connected to the driving end of the heat dissipation driving member, and the heat dissipation driving member is fixedly connected to the main air cover.

[0020] By adopting the above technical solution, when it is necessary to draw air into the air guiding cover, the heat dissipation driving member can be used to drive the control member to rotate, so as to draw and discharge the air in the box body.

[0021] Optionally, the control member includes a control disk fixedly connected to the driving end of the heat dissipation driving member, a plurality of control vanes fixedly connected to the control disk, and a control guiding cover fixedly connected to the plurality of control vanes. The control guiding cover is tubular and its two ends respectively face the control vanes and the guiding cover. The plurality of control vanes are used to deflect the air in the middle of the guiding cover towards the outside when rotating circumferentially.

[0022] By adopting the above technical solution, when it is necessary to pump air, only the heat dissipation driving member needs to be used to drive the control disk to rotate. At this time, the control vanes can deflect the air located at the center of the control disk towards the outside, so as to form a negative pressure between the guiding cover and the control disk, and draw the air in the main air duct into the air guiding cover through the guiding cover. And compared with the situation where no negative pressure can be formed on the rotation axis when driven by a fan and no high air pressure can be formed, using the control vanes to deflect the air can form a negative pressure at any position in the control disk, effectively increasing the pressure formed when pumping air, thereby reducing the rotation speed of the control disk when the required negative pressure is reached, so as to achieve the effect of energy saving.

[0023] Optionally, the heat dissipation driving member is located outside the air guiding cover and the heat dissipation driving member is located below the heat dissipation air duct.

[0024] By adopting the above technical solution, the heat dissipation driving component can be cooled by the air flow in the box body, and at the same time, the interference of the heat dissipation driving component on the air flow in the air guide cover can be reduced.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] During use, a relatively large negative pressure can be generated by the heat dissipation component, and air can be drawn into the main air duct at different positions in the box body, and discharged after being cooled by the air cooler of the air compressor itself. While effectively improving the impact of high-temperature air on the surrounding environment, the air cooler can also cool part of the air entering the box body to improve the cooling and heat dissipation effect on the compressor in the box body, etc., so as to achieve the improvement of heat dissipation efficiency while making full use of its own energy consumption.

Detailed implementation manners

[0037] The following further elaborates on this application Figures 1 - 9 in conjunction with the attached drawings.

[0038] Embodiment 1:

[0039] Referring to Figure 1 and Figure 2 , an air compressor side-opening cooling structure includes a box body 14. A plurality of first heat dissipation openings 141 are provided on the side of the box body 14, and a compressor 11, an oil-gas separator 12, and a cooler 13 are all arranged inside the box body 14.

[0040] Referring to Figure 2 and Figure 3 , an air guiding cover 15 is fixedly connected inside the box body 14. The air guiding cover 15 has an upper opening and side openings. The edge of the upper opening of the air guiding cover 15 is fixedly connected to the top wall of the box body 14. Some of the first heat dissipation openings 141 are vertically distributed and are arranged corresponding to the side openings of the air guiding cover 15.

[0041] Referring to Figure 3 and Figure 4 , a total air cover 4 is fixedly connected to the edge of the side opening of the air guiding cover 15. The total air cover 4 has a folded plate structure. The side edges of the total air cover 4 facing and away from a plurality of vertically distributed first heat dissipation openings 141 are both bent upward to form a total air duct 41. The air guiding cover 15 is communicated with the total air duct 41 through the side opening. Among them, an air outlet 142 communicating with the inside of the air guiding cover 15 is provided at the top of the box body 14, and a heat dissipation assembly 3 for discharging the air inside the air guiding cover 15 through the air outlet 142 is arranged inside the air guiding cover 15.

[0042] Specifically, the outer wall of the main air duct 4 facing one side of a plurality of vertically distributed first heat dissipation openings 141 is fixedly connected to the cooler 13, and the opening areas of the plurality of vertically distributed first heat dissipation openings 141 corresponding to the cooler 13 are larger than the sum of the opening areas of the other first heat dissipation openings 141 on the box body 14, so that the content of the air entering the box body 14 that contacts the cooler 13 and is cooled is relatively more, thereby being able to reduce the temperature of the air entering the box body 14. At the same time, it can also make the air flow into the box body 14 from multiple angles and cool components such as the compressor 11, reducing the dead corners of cooling to optimize the heat dissipation effect.

[0043] Refer to Figure 3 and Figure 4 , several heat dissipation air ducts 2 communicating with the inside of the main air duct 41 are arranged in the box body 14. In the embodiment of the present application, one heat dissipation air duct 2 is arranged. The heat dissipation air duct 2 is horizontally arranged and has a tubular structure. The heat dissipation air duct 2 communicates with the air guiding cover 15 through the main air duct 41. One end of the heat dissipation air duct 2 far from the main air duct 41 extends horizontally above the compressor 11, and a plurality of third heat dissipation openings 21 located above the compressor 11 are formed in the heat dissipation air duct 2, so that the hot air generated when the compressor 11 is in use can naturally flow upward and flow into the main air duct 41 through the third heat dissipation openings 21, and the air in the air guiding cover 15 is discharged through the air outlet 142 by the heat dissipation assembly 3, thereby being able to effectively optimize the heat dissipation effect.

[0044] Refer to Figure 2 and Figure 3 , further, the distance between the first heat dissipation opening 141 corresponding to the cooler 13 and the compressor 11 is greater than the distance between the other first heat dissipation openings 141 and the compressor 11, so that when in use, when the heat dissipation assembly 3 discharges the air from the air outlet 142 in the air guiding cover 15, the air entering through the first heat dissipation opening 141 corresponding to the cooler 13, after being cooled by the cooler 13, the cooled air can flow relatively sufficiently in the box body 14 and mix with the air flowing in through the other first heat dissipation openings 141, and then enter the main air duct 41 through the heat dissipation air duct 2, thereby being able to effectively make full use of the cooling effect of the cooler 13 to optimize the heat dissipation effect. Among them, wind shielding plates 143 in a grid-like structure are fixedly connected to the opening edges of the first heat dissipation opening 141 and the air outlet 142 to block external sundries.

[0045] Refer to Figure 3 and Figure 4, in addition, in order to further increase the disturbance effect on the air flow in the box body 14 and reduce the temperature of the air discharged from the air outlet 142; a plurality of vertically distributed second heat dissipation openings 42 are formed in the side part of the main air hood 4, the second heat dissipation openings 42 are located on the vertical outer wall of the main air hood 4 adjacent to the cooler 13, and the opening areas of the plurality of second heat dissipation openings 42 are smaller than the opening area of the first heat dissipation opening 141 corresponding to the cooler 13, and the height of the second heat dissipation openings 42 is higher than the height of the compressor 11. During use, since the second heat dissipation openings 42 are located on the outer wall of the main air hood 4 adjacent to the cooler 13, part of the air entering from the first heat dissipation opening 141 corresponding to the cooler 13 can flow through the second heat dissipation openings 42 and be introduced into the main air duct 41, so as to reduce the temperature of the air entering the air guiding hood 15. While reducing the temperature of the discharged air, it can also cause further turbulence of the air in the box body 14, thereby further reducing the dead angle during heat dissipation treatment of components such as the compressor 11 and optimizing the heat dissipation effect.

[0046] Wherein, a heat dissipation grille 421 or a heat dissipation baffle 422 is fixedly connected to the opening edge of the second heat dissipation opening 42. Specifically, at least one second heat dissipation opening 42 is fixedly connected to the heat dissipation grille 421, and the second heat dissipation opening 42 fixedly connected to the heat dissipation grille 421 is located above the second heat dissipation opening 42 fixedly connected to the heat dissipation baffle 422, so as to reduce the possibility of hot air accumulation in the box body 14 and further optimize the heat dissipation effect.

[0047] Refer to Figure 3 and Figure 5 , the heat dissipation assembly 3 includes a control member 31, a heat dissipation driving member 32 and a guiding hood 33. The control member 31 is rotatably arranged on the inner wall of the air guiding hood 15 and is used to introduce the air in the main air duct 41 into the air guiding hood 15. The control member 31 is fixedly connected to the driving end of the heat dissipation driving member 32, and the heat dissipation driving member 32 is used to drive the control member 31 to rotate. The guiding hood 33 is of a tubular structure, and one axial end of the guiding hood 33 is bent outward, so that the guiding hood 33 is of a tapered tubular structure. The large end edge of the guiding hood 33 is fixedly connected to the side opening edge of the air guiding hood 15, and the side opening edge of the air guiding hood 15 is adapted to the large end opening edge of the guiding hood 33. The small end of the guiding hood 33 is horizontal and faces the control member 31 to facilitate the control member 31 to drive the air flow.

[0048] Refer to Figure 3 and Figure 5, the control member 31 includes a control disk 311 fixedly connected to the output end of the heat dissipation driving member 32, a plurality of control vanes 312 arranged around the rotation axis of the driving end of the heat dissipation driving member 32, and a control guide cover 313 fixedly connected to the plurality of control vanes 312. The heat dissipation driving member 32 is a motor, and the heat dissipation driving member 32 is fixedly connected to the outer wall of the air guide cover 15 facing the compressor 11, and the heat dissipation driving member 32 is located below the heat dissipation air duct 2 to facilitate heat dissipation of the heat dissipation driving member 32. The output shaft of the heat dissipation driving member 32 penetrates into the air guide cover 15 and is fixedly connected to the control disk 311. The control disk 311 is arranged inside the air guide cover 15, and the control disk 311 is arranged vertically, and the rotation axis of the control disk 311 is arranged horizontally.

[0049] The control vane 312 is fixedly connected to the outer wall of the control disk 311 facing away from the heat dissipation driving member 32. The control vane 312 has an arc-shaped plate structure, and the central axis of its arc surface is parallel to the rotation axis of the control disk 311. The arc surface of the control vane 312 extends toward the central side of the control disk 311, and the central axis of the control disk 311 is located on the side of the opening of the arc surface of the control vane 312. When the control disk 311 rotates toward the side of the opening of the arc surface of the control vane 312, the air on the central side of the control guide cover 313 can be guided and stirred outward, thereby forming a negative pressure inside the control guide cover 313, sucking the air in the main air duct 41 into the air guide cover 15. At the same time, compared with the fact that the rotation center of ordinary fan blades cannot form a negative pressure, the negative pressure inside the control guide cover 313 can be made relatively more balanced and the formed air flow pressure can be greater to meet the need of wind pressure during heat dissipation.

[0050] Embodiment 2:

[0051] Refer to Figure 6 and Figure 7 , the difference between this embodiment and Embodiment 1 is that an oil-gas separation device 5 for gas-liquid separation and collection of the air flowing into the main air duct 41 is provided in the control guide cover 313 or the guide cover 33. Since during use, the compressor 11 will mix in a certain amount of oil and gas, and at the same time when the air flows through the cooler 13, the air flowing into the main air duct 41 from the box body 14 will be condensed and produce a mixture of oil and water, which will accumulate in the main air duct 41, and part of it will also be discharged through the air outlet 142, which will have an impact on the surrounding environment. At this time, through the separation and collection of the oil-gas separation device 5, the oil-water mixed liquid condensed and accumulated in the main air duct 41 during use can be effectively reduced, and while reducing the corrosion of the main air duct 41, the impact on the surrounding environment can also be improved.

[0052] Specifically, the upper part of the opening edge of the control guide cover 313 is the air inlet, and the bottom wall of the main air duct 41 is inclined or bent, and the air inlet of the control guide cover 313 is flush with the lower edge of the main air duct 41, so that the liquid condensed in the main air duct 41 can flow into the control guide cover 313 for discharge, and at the same time, it can also pass through the oil-gas separation device 5 for oil-gas separation.

[0053] Refer to Figure 7 and Figure 8 , the oil-gas separation device 5 includes a plurality of oil-gas separation blades 51. The oil-gas separation blades 51 are inclined, and the oil-gas separation blades 51 are fixedly connected to the inner wall of the control guide cover 313. Two intersecting intercepting surfaces 511 are formed on the side of the oil-gas separation blade 51 facing the main air duct 41. The two intercepting surfaces 511 of the same oil-gas separation blade 51 are arranged at an angle, and the opening of the angle faces the side of the air guide cover 15. The oil-gas separation blade 51 is strip-shaped and is inclined, and the oil-gas separation blade 51 extends downward and toward the side of the air guide cover 15, so that when air flows, it will condense on the surface of the oil-gas separation blade 51 by contacting the oil-gas separation blade 51.

[0054] The intercepting surface 511 has an arc-shaped structure, and the central axis of its arc extends along the length of the oil-gas separation blade 51. A plurality of intercepting grooves 512 are recessed in the intercepting surface 511. The intercepting grooves 512 extend along the length direction of the oil-gas separation blade 51, and a hook plate 513 extending along the length direction of the intercepting groove 512 is fixedly connected to the opening edge of the side of the intercepting groove 512 away from the main air duct 41. The included angle between the hook plate 513 and the tangential plane of the position of the connected intercepting surface 511 is 50°, so as to increase the probability of being intercepted when the air flow passes through the intercepting groove 512, and at the same time increase the contact area with the oil-gas separation blade 51, so that the water and oil liquid mixed in the air flow can condense and be intercepted in the intercepting groove 512, and then flow downward under the guiding of the intercepting groove 512 and the blowing action of the air flow.

[0055] Refer to Figure 7 and Figure 9 , a plurality of first discharge structures 314 respectively communicating with a plurality of intercepting grooves 512 are arranged at the bottom of the control guide cover 313. The plurality of first discharge structures 314 extend obliquely downward and are fixedly connected to a discharge pipe 315. The discharge pipe 315 is connected to the outside through a valve, so as to discharge the condensed oil liquid and water. And a flow inlet 316 communicating with the discharge pipe 315 is opened at the bottom of the control guide cover 313, so as to discharge the oil liquid and the like flowing in from the main air duct 41. Specifically, the flow inlet 316 is also connected with a pipe communicating with the outside, so as to discharge the mixture of water and oil liquid. Among them, the first discharge structure 314 can adopt a discharge hole opened at the bottom of the control guide cover 313 or a drain pipe fixedly connected to the control guide cover 313.

[0056] Refer toFigure 7 and Figure 8 Further, a plurality of intercepting grooves 512 are distributed along the air flow direction, so that air can be intercepted by the intercepting grooves 512 relatively sufficiently, and water and oil liquid in the air can be condensed in the intercepting grooves 512. The plurality of oil-gas separation vanes 51 are divided into multiple groups and the multiple groups are distributed along the axial direction of the control guide cover 313. The multiple oil-gas separation vanes 51 in the same group are distributed along the radial and horizontal directions of the control guide cover 313, and the projections of the multiple oil-gas separation vanes 51 in the same group along the axial direction of the control guide cover 313 coincide with each other, so that the air flowing through the control guide cover 313 can fully contact with the oil-gas separation vanes 51, optimizing the separation effect of water and oil liquid from air.

[0057] The adjacent two groups of oil-gas separation vanes 51 are arranged in a staggered manner, that is, the position of the gap between two adjacent oil-gas separation vanes 51 in the same group corresponds to the position of the oil-gas separation vanes 51 in the adjacent group, so that the air flowing through the control guide cover 313 can be separated by multiple groups of oil-gas separation vanes 51, further reducing the content of water and oil liquid in the discharged air. Wherein, the surface of the oil-gas separation vane 51 is plated with an oil-repellent layer, such as a nano-silica coating, to reduce the oil liquid attached to the surface of the oil-gas separation vane 51 and reduce the influence of the attached oil liquid on the intercepting effect of water and oil liquid.

[0058] Referring to Figure 7 and Figure 8 In order to further optimize the intercepting effect of the oil-gas separation vane 51 on water and oil liquid, a refrigerating and heating element 52 extending along its length direction is inserted inside the oil-gas separation vane 51. The refrigerating and heating element 52 is a semiconductor thermoelectric refrigeration sheet, so as to facilitate refrigerating or heating the oil-gas separation vane 51. Thus, when dissipating heat, the refrigerating and heating element 52 can refrigerate the oil-gas separation vane 51, so that water and oil mist in the air can be further condensed on the oil-gas separation vane 51, and the condensed liquid can be intercepted by the hook plate 513 and the intercepting grooves 512, thereby further reducing the content of oil liquid and water in the air entering the air guide cover 15 and discharged; at the same time, in cooperation with the air flow and the inclined oil-gas separation vanes 51, the condensed liquid can also be blown towards the first discharge structure 314; in addition, when heat dissipation or cleaning is not required, the refrigerating and heating element 52 can also heat the oil-gas separation vane 51, so as to cooperate with the air flowing through the control guide cover 313 to blow the oil liquid and moisture attached to the surfaces of the intercepting grooves 512 and the oil-gas separation vanes 51 towards the first discharge structure 314 to keep the surface of the oil-gas separation vane 51 clean.

[0059] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
