Description

Technical Field

[0001] This utility model relates to the technical field of air-cooled equipment, and in particular to an energy-saving air-cooled machine with divertable airflow. Background Technology

[0002] In industrial production and processing, temperature control of mechanical equipment operation, heat dissipation of precision electronic instruments, and temperature control of warehousing environment, air coolers, as a type of cooling equipment that uses air as a cooling medium and relies on forced air flow to achieve heat exchange, have become key equipment for achieving local or overall cooling in various scenarios due to their core advantages such as convenient and flexible installation, low daily maintenance costs, and no risk of leakage. They are widely used in CNC machine tools, injection molding machines, server rooms, electronic component production lines, and other places to ensure stable equipment operation, extend the service life of components, and maintain a stable temperature in the production environment. Existing air-cooled machines, such as the one disclosed in publication number CN218721986U, are energy-saving air-cooled machines with divertable cold air. These machines include an air-cooled chassis. During use, the installation and removal of the intake filter is relatively simple and quick, facilitating replacement or cleaning of the intake filter. Moreover, after replacement, the air intake filter can be sealed, preventing unfiltered gas from entering the chassis due to gaps between structures. However, the aforementioned air-cooled machine adopts a single air duct structure. The cold air is pressurized by the fan and discharged through a single exhaust grille. It can only effectively cool a fixed area directly in front of the exhaust grille. When facing scenarios such as multi-station production equipment that require simultaneous or independent cooling of multiple areas, this type of air-cooled machine cannot achieve the diversion and delivery of cold air, which can easily lead to uneven local cooling. Utility Model Content

[0003] To address the aforementioned issues, this invention provides an energy-saving air-cooled unit with divertable airflow. Through the design of three vertically aligned air ducts (left, center, and right) and electromagnetic valves electrically connected to the control panel, it can achieve multi-directional diversion of cold air and on-demand switching. It can provide cooling for specific areas individually or simultaneously cover multiple workstations and decentralized cooling scenarios, effectively avoiding the coverage limitations and cooling blind spots of traditional single air ducts.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an energy-saving air-cooled machine with divertable airflow, including a chassis, a sealing cover disposed on the surface of the chassis, and a control panel fixedly installed on the surface of the chassis; A cooling box is bolted to one side of the chassis. A fan is fixed to the surface of the cooling box via a frame. An air guide hood is fixed to the inner wall of the chassis and is connected to the cooling box. A left air duct, a middle air duct, and a right air duct are fixedly connected at equal intervals on the side of the air guide hood away from the cooling box. An air outlet hood is fixedly connected to the ends of the left air duct, the middle air duct, and the right air duct. Rotating rods are rotatably connected at equal intervals inside each air outlet hood. An air guide plate for changing the air direction is fixedly sleeved on the surface of each rotating rod.

[0005] By adopting the above technical solution, during use, the operator starts the equipment through the control panel on the surface of the chassis. The fan then draws in outside air into the cooling box. The cooled air enters the interconnected air guide hood, and is then distributed by the transition air box to the left, middle, and right air ducts, and finally discharged through the exhaust hood. During use, the on / off status of each air duct can be preset or adjusted through the control panel to achieve directional cooling for specific areas. The rotating rod inside the exhaust hood can also be adjusted to drive the air guide plate to rotate, changing the direction of the cold air to accurately cover the target area. After the operation is completed, the equipment can be turned off through the control panel. During maintenance, the sealing cover can be removed to clean or repair the internal components. The multi-duct design can simultaneously or individually meet the cooling needs of multiple areas without the need for additional equipment, reducing costs and saving space. The adjustable air guide plate can avoid uneven local cooling and is suitable for precision equipment or multi-workstation scenarios.

[0006] Furthermore, U-shaped clips are fixedly connected to the sides of the chassis near its four corners, and T-shaped blocks that are compatible with the U-shaped clips are fixedly connected to the side surfaces of the sealing cover near its four corners. When sealing, the T-shaped blocks are inserted into the slots opened on the surface of the U-shaped clips.

[0007] By adopting the above technical solution, when the chassis needs to be sealed after equipment assembly or maintenance, the operator only needs to align the sealing cover with the chassis and insert the T-shaped blocks at the four corners of the sealing cover into the slots on the U-shaped clips at the four corners of the chassis side to quickly connect and fix the sealing cover to the chassis. If the sealing cover needs to be opened for internal maintenance, simply pull the sealing cover in the opposite direction to disengage the T-shaped blocks from the slots on the U-shaped clips, and the sealing cover can be easily removed. Through the matching plug-in design of the T-shaped blocks and U-shaped clips, on the one hand, the sealing cover can be quickly disassembled and assembled without the need for additional tools such as bolts and screwdrivers, greatly simplifying the operation process and saving disassembly and assembly time during equipment maintenance. On the other hand, the symmetrically distributed snap-fit ​​structure at the four corners makes the connection between the sealing cover and the chassis more stable, preventing the sealing cover from loosening due to vibration during equipment operation, while effectively ensuring the internal sealing of the chassis and preventing external dust and impurities from entering the equipment.

[0008] Furthermore, the interior of the cooling box is fixedly connected with multiple heat dissipation fins at equal intervals, and the interior of the cooling box is also provided with a serpentine cooling pipe. The serpentine cooling pipe is inserted on the surface of the multiple heat dissipation fins, and the inlet and outlet pipes of the serpentine cooling pipe extend to the top of the cooling box.

[0009] By adopting the above technical solution, during equipment operation, external air is drawn into the cooling box by a fan, while coolant flows in through the inlet pipe of the serpentine cooling pipes, flowing within the serpentine pipe arrangement. Because the serpentine cooling pipes intersect the surface of the evenly spaced heat dissipation fins within the cooling box, the coolant exchanges heat with the fins during its flow, transferring heat from the cooling pipes to the fins. At this time, the air drawn in by the fan flows through the fins, quickly carrying away the heat from the fins, thus cooling the air. The coolant that has completed heat exchange flows out through the outlet pipe, and the cooled air enters the air guide shroud for further distribution. The serpentine cooling pipe design significantly increases the contact area between the coolant, air, and heat dissipation fins, extending the heat exchange time. Compared to straight-pipe cooling pipes, it has higher cooling efficiency and can quickly reduce the temperature of the air entering the cooling box. Moreover, the evenly spaced heat dissipation fins further expand the heat dissipation area, efficiently transferring heat from the serpentine cooling pipes. Combined with the airflow from the fan, this forms a "pipe-fin-air" coordinated heat dissipation mode, ensuring stable cooling performance.

[0010] Furthermore, electromagnetic valves are fixedly installed on the surfaces of the left duct, the middle duct, and the right duct, and the electromagnetic valves are electrically connected to the control panel.

[0011] By adopting the above technical solution, when the equipment is running, the operator sends commands through the control panel on the surface of the chassis. The solenoid valves on the surfaces of the left, middle, and right air ducts, which are electrically connected to the control panel, will automatically open or close according to the commands. If cooling of a single area is required, the solenoid valve of the corresponding air duct can be opened individually, while the others remain closed. If simultaneous cooling of multiple areas is required, the solenoid valves of multiple air ducts can be opened simultaneously, realizing the on-demand distribution of cold air to different air outlets. This enables on-demand cooling, is energy-efficient, and allows for flexible selection of which air ducts to open based on actual cooling needs, avoiding waste of cold air in non-target areas, reducing ineffective fan operation energy consumption, and improving the energy efficiency of the equipment.

[0012] Furthermore, the two left air ducts and the middle air duct are arranged perpendicularly, and the middle air duct and the right air duct are arranged perpendicularly.

[0013] By adopting the above technical solution, when the equipment is operating and delivering cold air, the left air duct, the middle air duct, and the right air duct are arranged in a "left-middle-right" distribution and are perpendicular to each other. This allows the cold air to be diverted from the air guide hood and delivered to the air outlet hoods at different locations along three mutually perpendicular directions, respectively covering the target cooling areas on the left, middle, and right sides of the equipment, achieving multi-directional and non-overlapping cold air coverage.

[0014] Furthermore, a protective shell is fixedly connected to the upper surface of the air outlet shroud, and a first rotating rod is rotatably connected to the inner wall of the protective shell. Multiple worm gears are fixedly sleeved on the surface of the first rotating rod at equal intervals. The top end of each rotating rod extends into the interior of the protective shell, and a worm wheel is fixedly connected to one end of each rotating rod extending into the interior of the protective shell. Each worm wheel meshes with the worm gear at a corresponding position. A micro motor is fixedly installed on the side surface of the protective shell, and the output end of the micro motor is fixedly connected to the first rotating rod.

[0015] By adopting the above technical solution, when it is necessary to adjust the air outlet direction during equipment operation, the operator can start the micro motor on the side surface of the protective shell through the control panel. The output end of the micro motor drives the first rotating rod connected to the inner wall of the protective shell to rotate. Multiple worm gears fixed at equal intervals on the surface of the first rotating rod rotate together. When the worm gears rotate, they drive the worm wheel to rotate synchronously, thereby driving the rotating rod and the air guide plate fixed on the surface to rotate, so as to achieve precise adjustment of the air outlet direction.

[0016] Furthermore, multiple bearing seats are rotatably fitted onto the surface of the first rotating rod at equal intervals, and the bearing seats are fixedly connected to the protective shell.

[0017] By adopting the above technical solution, when the air guide adjustment structure is running, the first rotating rod rotates under the drive of the micro motor. The multiple bearing seats (fixedly connected to the protective shell) that are equidistantly rotated on its surface provide stable support for the first rotating rod, ensuring that the first rotating rod always maintains coaxiality during high-speed rotation, avoiding swaying or deviation caused by excessive rod length, thereby ensuring precise meshing of the worm and worm wheel, and making the air guide plate adjustment action smooth and without jamming.

[0018] In summary, this utility model has the following beneficial effects: 1. In this application, the design of three vertical air ducts (left, middle and right) combined with electromagnetic valves electrically connected to the control panel can realize multi-directional air diversion and on-demand switching of cold air. It can provide cooling for specific areas individually or cover multiple workstations and decentralized cooling scenarios simultaneously, effectively avoiding the coverage limitations and cooling blind spots of traditional single air ducts. 2. In this application, the micro motor, the first rotating rod, the worm gear, the worm wheel, and the rotating rod, together with the bearing seat, provide stable support for the first rotating rod, which can drive the air guide plate to deflect synchronously and precisely, flexibly adjust the air outlet direction, prevent cold air from concentrating or becoming disordered, ensure uniform temperature in each cooling area, and meet the temperature control requirements of precision equipment. 3. In this application, the combination of serpentine cooling pipes and equally spaced heat dissipation fins in the cooling box expands the heat exchange area. Combined with the forced airflow of the fan, it forms a highly efficient and coordinated heat dissipation. At the same time, the air ducts are opened as needed to reduce ineffective cooling, and the bearing housing reduces transmission friction energy consumption, thereby improving the overall cooling efficiency while reducing the equipment's operating energy consumption. 4. In this application, the fan, solenoid valve and air guide adjustment can be controlled in an integrated manner through the control panel without manual operation; the plug-in structure of the chassis and the sealing cover, as well as the protection of the transmission components by the protective shell, not only simplifies the disassembly and maintenance process of the sealing cover, but also reduces the probability of failure of internal components and extends the service life of the equipment.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] like Figure 1-8 As shown in the figure, this application discloses an energy-saving air-cooled machine with air diversion, including a chassis 1, a sealing cover 5 disposed on the surface of the chassis 1, and a control panel 16 fixedly installed on the surface of the chassis 1. A cooling box 2 is fixedly connected to one side surface of the chassis 1 by bolts. A fan 3 is fixedly connected to the surface of the cooling box 2 by a frame. An air guide shroud 9 is fixedly connected to the inner wall of the chassis 1. The air guide shroud 9 is connected to the cooling box 2. A transition air box 10 is fixedly connected to the side surface of the air guide shroud 9 away from the cooling box 2. A left air duct 11, a middle air duct 12, and a right air duct 13 are fixedly connected at equal intervals on the side of the transition air box 10 away from the air guide shroud 9. An air outlet shroud 15 is fixedly connected to the end of each of the left air duct 11, the middle air duct 12, and the right air duct 13. A rotating rod 23 is rotatably connected at equal intervals inside each air outlet shroud 15. An air guide plate 24 for changing the air direction is fixedly sleeved on the surface of each rotating rod 23.

[0023] During operation, the operator starts the equipment via the control panel 16 on the surface of the chassis 1. The fan 3, fixed to the surface of the cooling box 2 by the frame, operates, drawing in outside air to cool it down before sending it into the air guide shroud 9 on the inner wall of the chassis 1, which is connected to the cooling box 2. The cooling air then enters the transition air box 10 on one side of the air guide shroud 9, and is evenly distributed by the transition air box 10 to the left air duct 11, the middle air duct 12, and the right air duct 13. It is then transported along the air ducts to the end air outlet shroud 15, and subsequently, the air guide plate 24 can be driven by the drive rotating rod 23. The deflection adjusts the air outlet direction to achieve directional cooling. When shutting down the equipment, the fan 3 can be turned off via the control panel 16. During maintenance, the sealing cover 5 can be opened to operate the internal components. The transition air box 10 ensures that the cold air is evenly distributed to the three air ducts, avoiding uneven air volume. The three air ducts can simultaneously or individually provide cooling for multiple areas, adapting to multi-workstation scenarios without the need for additional equipment. The cooperation between the air guide plate 24 and the rotating rod 23 can flexibly adjust the air direction, solving the problem of cooling blind spots or waste caused by the fixed air outlet of traditional air-cooled machines, and improving the accuracy of cooling.

[0024] Furthermore, U-shaped clips 7 are fixedly connected to the sides of the chassis 1 near its four corners, and T-shaped blocks 6 that are compatible with the U-shaped clips 7 are fixedly connected to the side surface of the sealing cover 5 near its four corners. When sealing, the T-shaped blocks 6 are inserted into the slots opened on the surface of the U-shaped clips 7.

[0025] When sealing the chassis 1 after equipment assembly or maintenance, the operator only needs to align the sealing cover 5 with the chassis 1, and insert the T-shaped blocks 6 at the four corners of the side surface of the sealing cover 5 into the corresponding slots on the surface of the U-shaped clips 7 at the four corners of the side surface of the chassis 1 to quickly complete the connection and fixation between the sealing cover 5 and the chassis 1. If it is necessary to open the sealing cover 5 to inspect or clean the internal components of the chassis 1 such as the air guide shroud 9 and the transition air box 10, simply pull the sealing cover 5 in the opposite direction to disengage the T-shaped blocks 6 from the slots of the U-shaped clips 7, and the sealing cover 5 can be easily removed without the need for screwdrivers, wrenches, or other additional tools. The sealing cover 5 can be installed and removed by simply connecting the T-shaped block 6 and the U-shaped clip 7, which greatly simplifies the operation process, saves time during equipment maintenance, and improves maintenance efficiency. Furthermore, the symmetrically distributed U-shaped clips 7 and T-shaped blocks 6 at the four corners make the connection between the sealing cover 5 and the chassis 1 more secure, preventing the sealing cover 5 from loosening due to vibration during equipment operation. At the same time, it effectively isolates external dust and impurities from entering the chassis 1, protecting core components such as the air guide cover 9, the transition air box 10, and the air duct, reducing component failures caused by contamination, and extending the service life of the equipment.

[0026] Furthermore, multiple heat dissipation fins 8 are fixedly connected at equal intervals inside the cooling box 2. A serpentine cooling pipe 4 is also provided inside the cooling box 2. The serpentine cooling pipe 4 is inserted on the surface of the multiple heat dissipation fins 8. The inlet and outlet pipes of the serpentine cooling pipe 4 extend to the top of the cooling box 2.

[0027] When the equipment is running, the fan 3 draws in outside air into the cooling box 2, while the coolant flows in through the inlet pipe of the serpentine cooling pipe 4 inside the cooling box 2. Because the serpentine cooling pipe 4 is inserted into the surface of the heat dissipation fins 8 that are evenly distributed inside the cooling box 2, the coolant will exchange heat with the heat dissipation fins 8 during the flow, transferring the heat inside the pipe to the fins. At this time, the air drawn in by the fan 3 flows through the heat dissipation fins 8, quickly carrying away the heat on the fins and lowering the air temperature. The coolant that has completed the heat exchange flows out through the outlet pipe of the serpentine cooling pipe 4, and the cooled air enters the air guide shroud 9 for further diversion. By setting the serpentine cooling pipe 4, the contact area between the coolant, the heat dissipation fins 8, and the air is greatly increased. Combined with the evenly distributed heat dissipation fins 8, the heat dissipation range is further expanded, forming a "pipe-fin-air" coordinated heat dissipation mode.

[0028] Furthermore, solenoid valves 14 are fixedly installed on the surfaces of the left duct 11, the middle duct 12, and the right duct 13, and the solenoid valves 14 are electrically connected to the control panel 16.

[0029] During operation, the operator sends commands via the control panel 16 on the surface of the chassis 1. The solenoid valves 14 on the surfaces of the left duct 11, middle duct 12, and right duct 13, which are electrically connected to the control panel 16, will automatically open or close according to the commands. If only a single area (such as the left workstation) needs cooling, the solenoid valve 14 of the left duct 11 can be opened individually, while the solenoid valves 14 of the middle duct 12 and right duct 13 remain closed, ensuring that cooling air is only delivered along the left duct 11 to the corresponding exhaust hood 15. If cooling is needed for multiple areas (such as...), the operator can control the solenoid valve 14 of the left duct 11 to open, while keeping the solenoid valves 14 of the middle duct 12 and right duct 13 closed. Simultaneous cooling on both the left and middle sides allows for the simultaneous opening of the solenoid valves 14 of the left duct 11 and the middle duct 12, enabling directional cold air distribution. This achieves on-demand cooling, energy conservation, and reduced consumption. The ducts that can be opened can be flexibly selected according to actual cooling needs, avoiding waste of cold air delivery to non-target areas and reducing the ineffective energy consumption of the fan 3. Furthermore, by independently controlling the operating status of the three ducts, customized cooling supply can be provided for the different heat dissipation needs of different areas in multi-station, decentralized cooling scenarios, improving the equipment's adaptability to diverse operating conditions.

[0030] Furthermore, the two left air ducts 11 and the middle air duct 12 are arranged vertically, and the middle air duct 12 and the right air duct 13 are arranged vertically.

[0031] After the cooling air is distributed to the left duct 11, the middle duct 12 and the right duct 13 through the transition air box 10, the cold air will be delivered in three mutually perpendicular directions because the two left ducts 11 are perpendicular to the middle duct 12 and the middle duct 12 is perpendicular to the right duct 13. The cold air from the left duct 11 can cover the left side of the equipment, the middle duct 12 covers the middle area and the right duct 13 covers the right side area, realizing multi-directional non-overlapping directional air supply and accurately matching the cooling needs of different directions.

[0032] Furthermore, a protective shell 17 is fixedly connected to the upper surface of the air outlet shroud 15. A first rotating rod 19 is rotatably connected to the inner wall of the protective shell 17. Multiple worm gears 20 are fixedly sleeved at equal intervals on the surface of the first rotating rod 19. The top end of each rotating rod 23 extends into the interior of the protective shell 17. A worm wheel 22 is fixedly connected to one end of each rotating rod 23 that extends into the interior of the protective shell 17. Each worm wheel 22 is meshed with the worm gear 20 at the corresponding position. A micro motor 18 is fixedly installed on the side surface of the protective shell 17. The output end of the micro motor 18 is fixedly connected to the first rotating rod 19.

[0033] During use, when the airflow direction needs to be adjusted, the operator activates the micro motor 18 on the side surface of the protective shell 17 on the air outlet cover 15 via the control panel 16. The output of the micro motor 18 drives the first rotating rod 19, which is rotatably connected to the inner wall of the protective shell 17, to rotate. Multiple worm gears 20, which are fixed at equal intervals on the surface of the first rotating rod 19, rotate simultaneously. The rotation of the worm gears 20 drives the worm wheel 22 to rotate synchronously, thereby causing the rotating rod 23 and the air guide plate 24 fixed on its surface to deflect, achieving precise adjustment of the airflow direction. The protective shell 17 then controls the internal transmission components. To achieve protection, a single micro motor 18 drives the first rotating rod 19, which in turn drives all the worm gears 20, worm wheels 22, and rotating rods 23 to move synchronously. This ensures that the deflection angles of multiple air guide plates 24 within the same air outlet hood 15 are exactly the same, avoiding airflow turbulence and ensuring stable cold air delivery direction. At the same time, the meshing transmission between the worm gear 20 and the worm wheel 22 has the characteristics of stable transmission ratio and good self-locking, which can precisely control the deflection angle of the air guide plates 24. Combined with the controllability of the micro motor 18, it can achieve fine adjustment of the airflow direction and adapt to the directional air delivery needs of different scenarios.

[0034] Furthermore, multiple bearing seats 21 are rotatably sleeved at equal intervals on the surface of the first rotating rod 19, and the bearing seats 21 and the protective shell 17 are fixedly connected.

[0035] When the micro motor 18 drives the first rotating rod 19 to rotate to adjust the angle of the air guide plate 24, the multiple bearing seats 21 (fixedly connected to the protective shell 17) that are equidistantly rotatably sleeved on the surface of the first rotating rod 19 will provide stable multi-point support for the first rotating rod 19, limit the radial sway of the rotating rod, and ensure that the first rotating rod 19 always maintains coaxial rotation. This ensures the precise meshing of the worm gear 20 on its surface with the worm wheel 22 at the top of the rotating rod 23, so that the adjustment action of the air guide plate 24 is smooth and without jamming.

[0036] The operating principle of the energy-saving air-cooled machine with air diversion in this embodiment is as follows: When starting the equipment, the operator issues a running command through the control panel 16 on the surface of the chassis 1. First, the fan 3 fixed to the frame on the surface of the cooling box 2 is triggered to operate. The fan 3 draws outside air into the cooling box 2. At the same time, the external coolant flows in through the inlet pipe of the serpentine cooling pipe 4 in the cooling box 2. Because the serpentine cooling pipe 4 is inserted through the surface of the heat dissipation fins 8 that are evenly distributed in the cooling box 2, the coolant exchanges heat with the heat dissipation fins 8 during the flow of the pipe, transferring the heat in the pipe to the fins. At this time, the air drawn in by the fan 3 flows through the heat dissipation fins 8, quickly carrying away the heat on the fins and completing the air cooling. The cooled coolant then flows out of the cooling box 2 through the outlet pipe of the serpentine cooling pipe 4. After cooling, the cold air enters the air guide shroud 9 on the inner wall of the chassis 1, which is connected to the cooling box 2. After being guided by the air guide shroud 9, it flows into the transition air box 10 fixed on one side. The transition air box 10 evenly distributes the cold air to the left air duct 11, the middle air duct 12 and the right air duct 13. At this time, the control panel 16 controls the electromagnetic valves 14 electrically connected to the surface of the three air ducts to open or close automatically according to the actual cooling requirements. If cooling of a single area is required, only the valve of the corresponding air duct is opened. If cooling of multiple areas is required simultaneously, multiple valves are opened, so that the cold air is delivered to the air outlet shroud 15 at the end along the selected air duct. When the air outlet direction needs to be adjusted, the micro motor 18 is started through the control panel 16. The output end of the micro motor 18 drives the first rotating rod 19, which is rotatably connected to the inner wall of the protective shell 17, to rotate. Multiple worm gears 20 on the surface of the first rotating rod 19 rotate synchronously with the rotating rod. The worm gears 20 drive the worm wheel 22 to drive the rotating rod 23 to rotate, thereby causing the air guide plate 24 fixed on the surface of the rotating rod 23 to deflect, so as to achieve precise adjustment of the air outlet direction and ensure that the cold air covers the target cooling area. During equipment operation, the chassis 1 and the sealing cover 5 are sealed by the U-shaped clips 7 and T-shaped blocks 6 at the four corners to prevent external dust from entering. If maintenance is required, pull the sealing cover 5 in the opposite direction to disengage the T-shaped block 6 from the slot of the U-shaped clip 7, and the sealing cover 5 can be opened to inspect the internal air guide shroud 9, transition air box 10 and other components. After maintenance, reconnect them to restore the seal.
