Description

Technical Field

[0001] This invention relates to the field of high-temperature cabinet air conditioning technology, specifically an integrated high-temperature cabinet air conditioner. Background Technology

[0002] High-temperature cabinet air conditioners are specifically designed for industrial electrical cabinets, power distribution cabinets, communication base stations, and other equipment. They control the internal temperature of the cabinet through cooling and ventilation to prevent equipment failure or performance degradation caused by high temperatures. High-temperature cabinet air conditioners can be installed in a side-mounted or door-mounted manner, making installation simple. They can be customized according to customer needs and are suitable for cabinets of different sizes and specifications to meet diverse application scenarios. The energy consumption of high-temperature cabinet air conditioners is related to the operation of the condenser and compressor.

[0003] For example, patent CN115355569A discloses a cabinet air conditioner, including a compressor, a condenser, and an evaporator, and also includes a water collection tray disposed in the lower region of the evaporator. The water collection tray is provided with a first connecting pipe, the first end of which is connected to the exhaust port of the compressor, and the second end of which is connected to the condenser. The water collection tray is disposed in the lower region of the evaporator so that the condensate produced by the evaporator flows into the water collection tray under the action of gravity. The first connecting pipe in the water collection tray connects the compressor and the condenser. The high-temperature and high-pressure refrigerant is discharged from the exhaust port of the compressor. After passing through the first connecting pipe, the condensate in the water collection tray performs the first cooling on the high-temperature and high-pressure refrigerant. By placing the water collection tray on the indoor circulation side of the cabinet air conditioner, the cooling effect of the condensate is utilized more effectively to improve the energy efficiency of the cabinet air conditioner. The structure of the water collection tray with the first connecting pipe is simple and has a higher degree of integration.

[0004] For example, patent CN222836999U discloses an air-cooled ultra-high temperature air conditioning device, belonging to the field of air conditioning equipment technology. It includes a cabinet, with a condenser installed on the inner bottom wall of the cabinet. Multiple heat dissipation fins are arranged on the outside of the condenser. A motor is installed on the outside of the cabinet, and a first sprocket and a second sprocket are connected via a toothed chain drive. A connecting rod is connected to the inner side of the toothed chain, and a brush is connected to the outer surface of the connecting rod. The outer surface of the brush slides in contact with one side of the heat dissipation fins. Through the cooperation between the support rail, the brush, the toothed chain, and the motor, the motor provides power to rotate the shaft. After the shaft rotates, the first sprocket, the second sprocket, and the toothed chain drive the connecting rod to move, which in turn moves the brush. As the brush moves, it cleans away dust adhering to the surface of the heat dissipation fins, improving the heat dissipation effect of the condenser.

[0005] For example, patent CN209147238U discloses a high-temperature special air conditioner, including an indoor cabinet. A support mechanism is fixedly installed at the bottom of the indoor cabinet, and the support mechanism includes a support base. An indoor air inlet is provided on the surface of the indoor cabinet, and an air outlet mechanism is installed on the surface of the indoor cabinet above the air inlet. The air outlet mechanism includes an air outlet, and a control mechanism is installed on the surface of the indoor cabinet above the air outlet mechanism. The control mechanism includes an LED display screen and control buttons. A dustproof auxiliary mechanism, including a sealing plate, is movably installed on the inner wall surface of the indoor cabinet. This utility model, through a series of structural features, ensures the heat dissipation and cooling effect inside the air conditioner while it operates normally, extends its service life, provides a certain degree of shock resistance, and ensures sufficient dustproof effect at the air outlet without affecting exhaust.

[0006] The condenser is the heat dissipation component of the server rack, and its heat dissipation capacity directly affects the compressor's discharge pressure. The higher the pressure, the greater the compressor's energy consumption. The cooling equipment of the server rack air conditioner is integrated into a relatively small space, and its heat dissipation capacity is limited. Some existing server rack air conditioners do not make it convenient to adjust the heat dissipation effect of the condenser. The longer the condenser runs, the lower its heat dissipation capacity becomes, which increases the compressor's energy consumption under high temperature conditions.

[0007] To address the aforementioned issues, there is an urgent need for innovative designs based on existing high-temperature cabinet air conditioners. Summary of the Invention

[0008] The purpose of this invention is to provide an integrated high-temperature cabinet air conditioner to solve the problems mentioned in the background art, where the condenser is the heat-dissipating component of the cabinet, and its heat dissipation capacity directly affects the compressor's discharge pressure. The higher the pressure, the greater the compressor's energy consumption. The cooling equipment of the cabinet air conditioner is integrated in a relatively small space, and its heat dissipation capacity is limited. Some existing cabinet air conditioners are not convenient to adjust and manage the heat dissipation effect of the condenser. The longer the condenser runs, the lower its heat dissipation capacity becomes, which increases the compressor's energy consumption under high temperature conditions.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an integrated high-temperature cabinet air conditioner, comprising a lower shell for heat dissipation through the external environment and an upper shell for cooling through the cabinet interior, wherein a heat insulation layer is fixedly installed between the lower shell and the upper shell; a condenser is fixedly installed in the lower shell, one end of the condenser is connected to a compressor via a pipe, and the other end of the condenser is connected to a dryer via a pipe, wherein the pipes on the compressor and the dryer are both connected to an expansion valve; a cooling fan corresponding to the condenser for auxiliary heat dissipation is also installed in the lower shell; an evaporator is fixedly installed in the upper shell, and two pipes on the evaporator pass through the heat insulation layer. The heat layer is connected to the expansion valve, and a negative pressure fan corresponding to the evaporator is installed in the upper shell to draw hot air from inside the cabinet. An air inlet corresponding to the negative pressure fan is opened on the upper shell, and an air outlet for discharging cold air is also opened in the upper shell. An upper partition is fixed between the air inlet and the air outlet in the upper shell, and a transmission channel for guiding cold air is opened between the upper shell, the heat insulation layer and the lower shell. A flow-dividing mechanism is set in the upper shell to control the direction of cold air transmission. The flow-dividing mechanism controls the cold air to enter the lower shell to reduce the operating temperature of the condenser, and the flow-dividing mechanism can adjust the size of the exhaust channel of the air outlet to adjust the wind speed.

[0010] Preferably, the diversion mechanism includes a through groove formed on the upper partition, in which a longitudinal diversion strip for diverting cold air is fixedly installed, and a transverse diversion strip is fixedly installed at the end of the upper housing away from the air outlet; a support base is fixedly installed on the bottom surface of the upper housing, and a guide plate is rotatably installed on the support base, and the guide plate is rotatably engaged with the end faces of the longitudinal and transverse diversion strips.

[0011] Preferably, a hydraulic transmission rod is rotatably connected to the upper housing, and the output end of the hydraulic transmission rod is rotatably connected to the guide plate.

[0012] Preferably, a slide rail is fixedly connected to the inner wall of the upper housing above and below the air outlet, and a flow limiting plate is slidably installed in the upper and lower slide rails; multiple large exhaust ports of the same size as the air outlet are equidistantly opened on the flow limiting plate, and small exhaust ports smaller than the area of ​​the large exhaust ports are also equidistantly opened on the flow limiting plate, with the large exhaust ports and small exhaust ports continuously spaced apart.

[0013] Preferably, a slider is slidably connected to the slide rail, and the slider is fixedly installed on the flow limiting plate; a guide channel is fixedly located at the center of the upper end face of the slide rail, and a lifting frame is slidably connected longitudinally to the guide channel and the slide rail; an auxiliary push rod is rotatably connected to the lifting frame, and the other end of the auxiliary push rod is rotatably connected to the slider.

[0014] Preferably, a main push rod is rotatably connected to the lifting frame, and the other end of the main push rod is rotatably connected to the surface of the guide plate.

[0015] Preferably, the lower housing is provided with an auxiliary cooling mechanism to activate the condenser and increase the air cooling effect, and the lower housing is provided with a venting mechanism to clear the heat dissipation vents and accelerate the heat dissipation. The cooling mechanism and the venting mechanism operate in conjunction.

[0016] Preferably, a lower partition plate is fixedly connected to the upper end face of the condenser in the lower housing, and a rectangular bracket is fixedly connected to the lower partition plate and the opening above the condenser. A sliding rod is fixedly connected to the rectangular bracket, and a sealing plate is slidably connected to the sliding rod. The sealing plate is fitted into the rectangular bracket. A cylinder is fixedly installed on the rectangular bracket, and the output end of the cylinder is fixedly connected to the sealing plate.

[0017] Preferably, the unblocking mechanism includes a column fixedly installed inside the lower housing, a sliding plate slidably mounted on the column, and a movable frame fixedly mounted on the sliding plate; a plurality of cylindrical rods are fixedly mounted at equal intervals on the movable frame, and the cylindrical rods are disposed through the heat dissipation vent.

[0018] Preferably, a pull rope is fixedly connected to the slide plate, the other end of the pull rope is fixedly connected to the sealing plate, and the pull rope is slidably connected to the lower partition plate; a vibration spring is elastically connected between the slide plate and the column.

[0019] Compared with the prior art, the beneficial effects of the present invention are: the integrated high-temperature cabinet air conditioner adjusts the cold air output path according to the change of condenser operating temperature, so that a part of the cold air is output through the condenser, reducing the operating temperature of the condenser, thereby reducing the operating energy consumption of the compressor and improving the energy-saving effect of the overall cabinet air conditioner. At the same time, it can adjust the wind speed of the cold air delivered to the cabinet, and maintain the cooling effect inside the cabinet while diverting the cold air.

[0020] Furthermore, the upper housing is equipped with a flow-diverting mechanism to control the direction of cold air transmission. The hydraulic transmission rod controls the rotation of the guide plate, switching the engagement state of the guide plate with the longitudinal and transverse flow-diverting strips. When the guide plate is engaged with the transverse flow-diverting strip, the output cold air is completely discharged outward through the air outlet, achieving the effect of cooling the inside of the cabinet.

[0021] When the guide plate is engaged with the longitudinal flow divider, most of the output cold air is discharged outward through the air outlet, and a small amount of cold air enters the lower housing through the transmission channel, and cools the condenser inside the lower housing. The condenser operates under good heat dissipation conditions, which can reduce the energy consumption of the compressor and improve the overall energy-saving effect of the equipment.

[0022] When controlling the airflow distribution, the rotation of the guide plate can control the lateral movement of the two sets of flow restrictors. The movement of the flow restrictors connects the small exhaust port and the air outlet, reducing the ventilation volume of the air outlet and adjusting the air speed of the exhaust air. This prevents local overcooling and uneven heat transfer caused by a reduction in the amount of cool air, thus maintaining the cooling effect inside the cabinet.

[0023] Furthermore, the lower housing is equipped with an auxiliary cooling mechanism to open the condenser and increase the air-cooling effect. The operating cylinder controls the directional movement of the sealing plate, so that the sealing plate moves away from the top of the condenser cover, so that the upper end of the condenser is in an open state, so that the cold air transmitted from inside the lower housing can quickly enter the condenser, thereby assisting the condenser in heat dissipation and cooling.

[0024] The lower housing is equipped with a venting mechanism to accelerate heat dissipation. During the opening and closing of the sealing plate, the pull rope can be stretched or released. The pull rope, together with the vibration spring, can control the longitudinal movement of the sliding plate on the column, thereby driving the moving frame and the cylindrical rod to move longitudinally. The cylindrical rod moves longitudinally through the vent, which can clean the mesh-like dust blocking the vent, maintain the ventilation and heat dissipation effect of the vent, and further assist the condenser in heat dissipation and cooling.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figures 1-7The present invention provides the following technical solution: an integrated high-temperature cabinet air conditioner, comprising a lower shell 1 for heat dissipation through the external environment and an upper shell 3 for cooling through the interior of the cabinet. A heat insulation layer 2 is fixedly installed between the lower shell 1 and the upper shell 3. A condenser 4 is fixedly installed in the lower shell 1. One end of the condenser 4 is connected to a compressor 5, and the other end of the condenser 4 is connected to a dryer bottle 6. The pipes on the compressor 5 and the dryer bottle 6 are both connected to an expansion valve 7. A cooling fan 10 is also installed in the lower shell 1 to assist in heat dissipation next to the condenser 4. An evaporator 8 is fixedly installed in the upper shell 3. Two pipes on the evaporator 8 pass through the heat insulation layer 2 and the expansion valve 7. The components are interconnected, and a negative pressure fan 9 corresponding to the evaporator 8 is installed in the upper housing 3 to draw hot air from the cabinet. An air inlet 11 corresponding to the negative pressure fan 9 is opened on the upper housing 3, and an air outlet 12 for discharging cold air is also opened in the upper housing 3. An upper partition 13 is fixed between the air inlet 11 and the air outlet 12 in the upper housing 3, and a transmission channel 15 for guiding cold air is opened between the upper housing 3, the heat insulation layer 2 and the lower housing 1. A diversion mechanism is provided in the upper housing 3 to control the direction of cold air transmission. The diversion mechanism controls the cold air to enter the lower housing 1 to reduce the operating temperature of the condenser 4, and the diversion mechanism can adjust the size of the exhaust channel of the air outlet 12 to adjust the wind speed.

[0043] Please see Figures 3-9 The air diversion mechanism includes a through groove 14 formed on the upper partition 13, in which a longitudinal air diversion strip 18 for diverting cold air is fixedly installed. A transverse air diversion strip 19 is fixedly installed at the end of the upper housing 3 away from the air outlet 12. A support base 16 is fixedly installed on the bottom surface of the upper housing 3, and a guide plate 17 is rotatably installed on the support base 16. The guide plate 17 is rotatably engaged with the end faces of the longitudinal air diversion strip 18 and the transverse air diversion strip 19. A hydraulic transmission rod 20 is rotatably connected to the upper housing 3, and the output end of the hydraulic transmission rod 20 is rotatably connected to the guide plate 17.

[0044] Please see Figures 5-10 A slide rail 21 is fixedly connected to the inner wall of the upper shell 3 above and below the air outlet 12. A flow limiting plate 22 is horizontally slidably installed in the upper and lower slide rails 21. Multiple large exhaust ports 221 of the same size as the air outlet 12 are equidistantly opened on the flow limiting plate 22. Small exhaust ports 222 with a smaller area than the large exhaust ports 221 are also equidistantly opened on the flow limiting plate 22. The large exhaust ports 221 and small exhaust ports 222 are continuously spaced apart.

[0045] Please see Figures 6-11A slider 23 is slidably connected to the slide rail 21, and the slider 23 is fixedly installed on the flow restrictor 22. A guide channel 24 is fixedly fixed in the center of the upper end face of the slide rail 21. A lifting frame 25 is longitudinally slidably connected to the guide channel 24 and the slide rail 21. A secondary push rod 26 is rotatably connected to the lifting frame 25, and the other end of the secondary push rod 26 is rotatably connected to the slider 23. A main push rod 27 is rotatably connected to the lifting frame 25, and the other end of the main push rod 27 is rotatably connected to the surface of the flow guide plate 17.

[0046] When the cabinet air conditioner is running, the compressor 5 serves as the power source for the entire refrigeration cycle. It compresses the low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous state. The gaseous refrigerant is then transferred to the condenser 4, where, under the cooling effect of the cooling fan 10, the high-temperature, high-pressure gaseous refrigerant is liquefied into a medium-temperature, high-pressure liquid refrigerant. The medium-temperature, high-pressure liquid refrigerant then passes through the dryer bottle 6 and the expansion valve 7 to reduce its pressure and temperature, becoming a low-temperature, low-pressure gas-liquid mixture in preparation for heat absorption. Finally, the low-temperature, low-pressure refrigerant enters the evaporator 8. The negative pressure fan 9 draws in the gas inside the cabinet, and the gas enters the evaporator 8 through the air inlet 11. Through heat exchange, the gas temperature is rapidly reduced. The cooled gas then re-enters the cabinet through the air outlet 12, and this cycle continues to achieve the purpose of cooling.

[0047] The energy consumption of compressor 5 is related to the energy efficiency of the entire air conditioning system. The heat dissipation of condenser 4 affects the discharge pressure of compressor 5; the higher the pressure, the greater the energy consumption of compressor 5. Therefore, maintaining stable cooling and heat dissipation of condenser 4 can improve the overall energy efficiency of the system. A temperature sensor is installed in condenser 4 to detect changes in internal heat dissipation temperature. Under normal operating conditions, the guide plate 17 rotates and engages with the transverse diverter bar 19. At this time, the low-temperature gas in the channel 14 is completely discharged outward through the air outlet 12 under the guidance of the guide plate 17. When the heat dissipation temperature of condenser 4 exceeds the normal heat dissipation... When the flow is within the specified range, the hydraulic transmission rod 20 can be controlled to operate. The hydraulic transmission rod 20 pushes the guide plate 17 to rotate, so that the guide plate 17 switches from the state of being engaged with the transverse diverter 19 to the state of being engaged with the longitudinal diverter 18. At this time, most of the low-temperature gas in the channel 14 enters the cabinet through the air outlet 12 after being guided by the guide plate 17. A small amount of low-temperature gas enters the lower housing 1 through the transmission channel 15. The cold air sinks and flows through the condenser 4 inside the lower housing 1 to assist the condenser 4 in cooling and heat dissipation, thereby keeping the compressor 5 in normal operation and reducing equipment energy consumption.

[0048] When controlling the airflow distribution, the guide plate 17 rotates. At this time, the main push rod 27, connected between the guide plate 17 and the lifting frame 25, rotates at both ends. The rotating main push rod 27 pushes the lifting frame 25 upwards through the guide channel 24. Simultaneously, the auxiliary push rod 26, connected between the lifting frame 25 and the slider 23, rotates at both ends. The rotating auxiliary push rod 26 pushes the slider 23 laterally on the slide rail 21. The slider 23 drives the flow-limiting plate 22 to move laterally synchronously, causing the small exhaust port 222 on the flow-limiting plate 22 to move and connect with the air outlet 12 (for normal cooling). In this case, the large exhaust vent 221 on the flow restrictor 22 is connected to the air outlet 12, which adjusts the air velocity of the cold air entering the cabinet. When the air is split, the amount of cold air is reduced. By adjusting the air velocity of the outlet, the cold air can be kept to enter the cabinet faster, thus maintaining the cooling effect. When the large exhaust vent 221 is aligned with the air outlet 12, the cold air enters the cabinet completely through the air outlet 12. When the air volume is large, increasing the air outlet area can avoid local overcooling caused by excessive air velocity, so that the air velocity of the cold air entering the cabinet can be adjusted automatically according to the cold air circulation path.

[0049] Example 2: Please refer to Figure 12 and Figure 13 Based on Embodiment 1, an auxiliary cooling mechanism and a dredging mechanism are also disclosed. The specific structure is as follows: an auxiliary cooling mechanism for opening the condenser 4 to increase the air cooling effect is provided in the lower housing 1, and a dredging mechanism for dredging the heat dissipation port 37 to accelerate the heat dissipation is provided in the lower housing 1. The cooling mechanism and the dredging mechanism operate in conjunction.

[0050] Please see Figure 13 and Figure 14 A lower partition plate 28 is fixedly connected to the upper end face of the condenser 4 in the lower housing 1. A rectangular bracket 29 is fixedly connected to the lower partition plate 28 and the opening above the condenser 4. A slide rod 30 is fixedly connected to the rectangular bracket 29. A sealing plate 31 is slidably connected to the slide rod 30. The sealing plate 31 is fitted into the rectangular bracket 29. A cylinder 32 is fixedly installed on the rectangular bracket 29. The output end of the cylinder 32 is fixedly connected to the sealing plate 31.

[0051] Please see Figures 13-15 The unblocking mechanism includes a column 33 fixedly installed inside the lower housing 1. A sliding plate 34 is slidably mounted on the column 33, and a movable frame 35 is fixedly mounted on the sliding plate 34. Multiple cylindrical rods 36 are fixedly mounted at equal intervals on the movable frame 35, and the cylindrical rods 36 are disposed through the heat dissipation vent 37. A pull rope 341 is fixedly connected to the sliding plate 34, and the other end of the pull rope 341 is fixedly connected to the sealing plate 31. The pull rope 341 is also slidably connected to the lower partition 28. A vibration spring 342 is elastically connected between the sliding plate 34 and the column 33.

[0052] When the cold air is diverted and controlled, some of the cold air enters the lower housing 1 through the transmission channel 15. At this time, the operating cylinder 32 controls the sealing plate 31 to move. The sealing plate 31 is sleeved on the slide rod 30 and moves away from the upper opening of the condenser 4. The cold air in the lower housing 1 sinks into the condenser 4, and works with the cooling fan 10 to help the condenser 4 cool down quickly, so as to avoid the compressor 5 from operating under a large energy consumption state.

[0053] During the movement of the sealing plate 31, the pull rope 341 can be controlled to move. After the pull rope 341 is released, the tension on the sliding plate 34 is loosened. At this time, under the elastic tension of the vibration spring 342, the sliding plate 34 can be controlled to move on the column 33. The sliding plate 34 drives the moving frame 35 and the cylindrical rod 36 to move synchronously, so that the cylindrical rod 36 moves longitudinally through the heat dissipation port 37. When the sealing plate 31 moves back to its original position, the pull rope 341 is stretched. The pull rope 341 drives the sliding plate 34 to move on the column 33. It can control the moving frame 35 and the cylindrical rod 36 to move in opposite directions. This process is repeated. During the opening or closing of the upper end of the condenser 4, the cylindrical rod 36 can be controlled to move longitudinally to clean the mesh-like dust and debris inside the heat dissipation port 37, keep the heat dissipation port 37 unobstructed, and further assist the condenser 4 in heat dissipation and cooling.
