Description

Technical Field

[0001] The present invention belongs to the technical field of energy saving for computer room air conditioners, and particularly relates to an energy saving device for computer room air conditioners. Background Art

[0002] A computer room is a place where data centers or servers are concentrated, and usually needs to maintain a low temperature environment for a long time to ensure the normal operation of equipment. However, the air conditioning system accounts for a large proportion of energy consumption in the computer room, especially in large data centers or cloud computing centers. With the increase in energy costs and the emphasis on environmental protection, energy saving has become an important goal to reduce energy waste and operating costs. Moreover, the refrigerants used in computer room air conditioning systems may have a negative impact on the atmospheric environment. Therefore, optimizing the air conditioning system and improving its energy efficiency not only helps to save energy, but also reduces environmental pollution.

[0003] Existing computer room air conditioners usually use the air-cooled method to achieve cooling. If the temperature in the area where the computer room is located is high or the air humidity is large, the cooling effect of the air-cooled air conditioner will be affected, resulting in the air conditioner being unable to achieve the ideal cooling effect. In this case, additional refrigeration equipment may need to be added or the working load of the air conditioner may need to be increased, thereby increasing energy consumption. Moreover, in a high-temperature environment, the heat dissipation capacity of the air-cooled air conditioner is also limited by the external temperature. When the environmental temperature is high, the cooling effect of the air conditioner will decrease significantly, resulting in increased energy consumption. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an energy saving device for computer room air conditioners.

[0005] The technical solution adopted to solve the above technical problem is: an energy saving device for computer room air conditioners, including an air conditioner cabinet. Inside the air conditioner cabinet, a fan, a compressor and a humidifier are provided. The inner wall of the air conditioner cabinet above the fan is welded with an inclined baffle plate. An air outlet is opened on the air conditioner cabinet facing the inclined surface of the baffle plate. At the same time, air return openings and water pipes are respectively penetrated through both sides of the bottom of the air conditioner cabinet, and the air return openings and the water pipes are located at the bottom of the compressor and the humidifier. A control panel fixedly installed on the outer wall of the air conditioner cabinet is arranged in the middle of the air return opening and the air outlet. A pretreatment mechanism for reducing the temperature of the hot air entering the air conditioner cabinet from the air return opening is arranged at the center of the bottom of the air conditioner cabinet, and the compressor and the humidifier are installed on one side of the top surface of the pretreatment mechanism. A heat exchange promoting mechanism for reducing the cooling time of the computer room air conditioner is arranged above the fan.

[0006] Through the above technical solution, when hot air passes through the water curtain, it will exchange heat with water, rapidly reducing the air temperature. This cooling method can effectively reduce the air temperature entering the air-conditioning system, thereby reducing the burden on the air-conditioning system and improving energy efficiency. At the same time, the elastic and vibrating evaporator surface can improve the heat exchange efficiency. When the cooled air passes through the evaporator, the vibration helps to better conduct heat evenly, enabling the evaporator surface to conduct heat exchange more efficiently, thus improving the overall cooling capacity of the air conditioner.

[0007] Further, the pretreatment mechanism includes a first fixing plate fixedly connected to the inner wall of the air-conditioning cabinet. A notch is formed through one side of the first fixing plate. At the same time, a compressor and a humidifier are installed on the top surface of the first fixing plate away from the notch. A second water tank is clamped at the center of the first fixing plate. Two inclined filter plates are welded to both sides of the top of the second water tank. The filter plates communicate with the bottom of the first fixing plate. Two second fixing plates are fixedly connected to the bottom surface of the second water tank. The other ends of the two second fixing plates are fixedly connected to a first water tank. The first water tank is located at the center of the bottom of the air-conditioning cabinet. One side of the first water tank is fixedly connected through a water pipe that is connected and fixed to the air-conditioning cabinet at the heat dissipation port.

[0008] Through the above technical solution, in an environment with high humidity, ordinary air-cooled air conditioners may be affected because the heat exchange efficiency of humid air is relatively low. The water curtain cooling absorbs the heat in the air and takes it away, and part of the moisture will also be adsorbed or condensed by the water curtain, thus helping the air conditioner maintain a relatively stable humidity level and improving the refrigeration efficiency.

[0009] Further, a shielding frame is welded to the top edge of the first water tank. One end of the shielding frame is located at the notch of the first fixing plate. Two through pipes are fixedly connected to both sides of the first water tank. The other ends of the through pipes are fixedly connected through the shielding frame. At the same time, the through ends of the through pipes are fixedly connected and communicated with the second water tank. A pump body is installed in the middle of the through pipe, and the inside of the through pipe is communicated with the inside of the pump body. One end of the second fixing plate is passed through the shielding frame and connected and fixed to the pump body. A circular groove and two water troughs are formed inside the pump body, and the two water troughs coincide with the two end points of the circular groove. A circular plate is rotatably connected to the center of the circular groove, and the center of the circular plate does not coincide with the center of the circular groove.

[0010] Further, sliding rods are slidably connected through both sides of the pump body. A sliding plate is welded to one end of the sliding rod facing the circular plate. The sliding plate is located inside the pump body and slidably connected thereto. A spring is fixedly connected to one side of the sliding plate. The other end of the spring is connected and fixed to the inner wall of the pump body. The sliding rod is located inside the spring, and one end of the sliding rod facing the circular plate is slidably connected to the circular plate.

[0011] Through the above technical solution, the water curtain cooling not only reduces the inlet air temperature, but also enhances the air fluidity, improves the heat exchange effect of the air conditioner. By optimizing the air circulation, the air conditioner can absorb and release heat more efficiently, thereby enhancing the overall cooling effect.

[0012] Further, a first fan is provided on one side of the shielding frame, and both ends of the first fan are rotatably connected to a support plate. At the same time, the bottom end of the support plate is fixedly connected to the bottom of the air conditioner cabinet. A synchronous belt assembly is provided on the side of the pump body away from the shielding frame. One connecting shaft of the synchronous pulley in the synchronous belt assembly is rotatably connected through the pump body. At the same time, the penetrating end of one connecting shaft of the synchronous pulley in the synchronous belt assembly is fixedly connected to the circular plate in the pump body.

[0013] Further, the penetrating end of one connecting shaft of the synchronous pulley in the synchronous belt assembly is located at the center of the circular groove. The other connecting shaft of the synchronous pulley in the synchronous belt assembly is rotatably connected through the support plate, and the penetrating end of the other connecting shaft of the synchronous pulley in the synchronous belt assembly is fixedly connected to the first fan.

[0014] Through the above technical solution, the two water curtains can block the dust or pollutants in the external air inhaled by the air conditioning system, purify the air, and reduce the impact of the dust or pollutants in the air on the components inside the air conditioner.

[0015] Further, the heat exchange promoting mechanism includes two first connecting plates fixedly connected to the inside of the air conditioner cabinet. A second fan is rotatably connected between the two first connecting plates. The first connecting plate is rotatably connected through the U-shaped rod on the side away from the second fan. The penetrating end of the U-shaped rod is fixedly connected to the second fan. At the same time, the other end of the U-shaped rod is rotatably connected to the inner wall of the air conditioner cabinet. A rotating plate is rotatably connected through the middle of the U-shaped rod. A metal strip arranged in a semi-circular structure is rotatably connected to the end of the rotating plate away from the U-shaped rod. At the same time, the connection part between the rotating plate and the metal strip is located in the middle of the metal strip.

[0016] Through the above technical solution, the jitter helps to remove the pollutants accumulated on the surface of the evaporator, reduce the accumulation of substances such as dust and oil stains, and reduce the risk of equipment failure caused by pollutant blockage.

[0017] Further, both ends of the metal strip are rotatably connected to a second connecting plate, and the other end of the second connecting plate is rotatably connected to a support frame. Limiting strips fixedly connected to the inner wall of the air conditioner cabinet are provided on both sides of the support frame. The two limiting strips horizontally limit the support frame. At the same time, the support frame is slidably connected to the limiting strips. A plurality of evaporators are installed on the top of the support frames.

[0018] Through the above technical solution, the stagnant air for a long time may cause corrosion on the surface of the evaporator. Especially when there is moisture in the computer room, appropriate elastic jitter can reduce the accumulation of moisture, reduce the risk of corrosion, and extend the service life of the evaporator.

[0019] The beneficial effects of the present invention are as follows: (1) By adopting a pretreatment mechanism in the present invention, when hot air enters the air conditioner cabinet from the air return opening, it drives the first fan to rotate and enters the shielding frame. The rotation of the first fan drives the synchronous belt assemblies on both sides to transmit power, causing the circular plate in the pump body to rotate with the center of the circular groove as the origin. As a result, the sliding rods on both sides are squeezed, and with the cooperation of springs, they move back and forth in the pump body. Then, the tap water in the first water tank is pumped out, passes through the through pipe and the water tank in the pump body, and enters the second water tank. When the water level in the second water tank continuously rises and overflows from the top of the second water tank, the tap water in the second water tank moves towards the filter plates on both sides, and then, under the action of gravity, it falls back into the first water tank through the filter holes of the filter plates. This cycle forms two water curtains. The hot air is initially cooled by passing through the first water curtain and then further cooled by passing through the second water curtain. This process helps to effectively reduce the temperature of the hot air entering the air conditioning system, thereby improving the overall cooling efficiency of the air conditioner. In a high-temperature environment, the water curtain can significantly reduce the air temperature, reduce the load on the air conditioning system, enhance the refrigeration effect, and moreover, reduce the energy consumption and operating burden required by the air conditioner itself during the refrigeration process, effectively alleviating the pressure on the compressor and other refrigeration components, thereby improving the working efficiency of the air conditioner and extending its service life;

[0020] (2) By adopting a heat exchange promotion mechanism in the present invention, when the pre-treated air continues to move upward under the action of the fan, it can drive the second fan to rotate, thereby driving the U-shaped rods on both sides to rotate, prompting the rotating plate to move up and down reciprocally. At the same time, the rotating plate and the U-shaped rods rotate relative to each other. As a result, the metal strip connected to the other end of the rotating plate rotates relative to the rotating plate and moves up and down reciprocally following the rotating plate, causing the metal strip to vibrate up and down reciprocally, driving the top support frame to move in the same manner between the two limiting strips. The evaporator connected to the top moves synchronously with the support frame. Moreover, while the second connecting plate moves synchronously with the metal strip, the second connecting plate rotates relative to the support frame and the metal strip respectively. By making the evaporator vibrate slightly elastically, it can effectively prevent the evaporator from icing, improve the heat exchange efficiency, reduce the accumulation of pollutants, improve the air flow distribution, and reduce corrosion.

Detailed implementation manners

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] As Figures 1 - 3 shown, an energy-saving device for a computer room air conditioner in this embodiment includes an air conditioner cabinet 11. Inside the air conditioner cabinet 11, a blower 18, a compressor 19 and a humidifier 110 are provided. And on the inner wall of the air conditioner cabinet 11 above the blower 18, a deflector 17 is welded and arranged obliquely. The blower 18 can circulate air to accelerate the heat exchange process. An air outlet 14 is opened on the air conditioner cabinet 11 facing the inclined surface side of the deflector 17. And on both sides of the bottom of the air conditioner cabinet 11, an air return port 13 and a water pipe 16 are respectively penetrated. When hot air passes through the water curtain, it will exchange heat with water, rapidly reducing the air temperature. This cooling method can effectively reduce the air temperature entering the air conditioning system, thereby reducing the burden on the air conditioning system and improving energy efficiency. At the same time, the surface of the elastically vibrating evaporator 111 can increase the heat exchange efficiency. When the cooled air passes through the evaporator 111, the vibration helps to better evenly conduct heat, enabling the surface of the evaporator 111 to perform heat exchange more efficiently, thereby improving the overall cooling capacity of the air conditioner. At the same time, the air return port 13 and the water pipe 16 are located at the bottom of the compressor 19 and the humidifier 110. The compressor 19 is responsible for compressing the refrigerant gas and sending it into the condenser. By increasing the pressure and temperature of the refrigerant, the refrigerant can release heat and complete the refrigeration process. A control panel 12 fixedly installed on the outer wall of the air conditioner cabinet 11 is provided in the middle of the air return port 13 and the air outlet 14, connecting the air conditioner cabinet 11 and its internal components to the existing air conditioner outdoor unit.

[0037] As Figures 1 - 11As shown, a pretreatment mechanism 2 for reducing the temperature of the hot air entering the air conditioner cabinet 11 from the air return opening 13 is provided at the center of the bottom of the air conditioner cabinet 11. The pretreatment mechanism 2 includes a first fixing plate 28 fixedly connected to the inner wall of the air conditioner cabinet 11. A notch 210 is formed through one side of the first fixing plate 28. At the same time, the compressor 19 and the humidifier 110 are installed on the top surface of the first fixing plate 28 away from the notch 210. A second water tank 29 is engaged at the center of the first fixing plate 28. Two filter plates 211 are welded on both sides of the top of the second water tank 29 and are inclined. At the same time, the filter plates 211 communicate with the bottom of the first fixing plate 28. Two second fixing plates 212 are fixedly connected to the bottom surface of the second water tank 29, and the other ends of the two second fixing plates 212 are fixedly connected to a first water tank 21. A shielding frame 25 is welded at the top edge of the first water tank 21. A first fan 27 is provided on one side of the shielding frame 25. Both ends of the first fan 27 are rotatably connected to a support plate 26. In a humid environment, ordinary air-cooled air conditioners may be affected because the heat exchange efficiency of humid air is low. The water curtain cooling absorbs the heat in the air and takes it away, and part of the moisture will also be adsorbed or condensed by the water curtain, thus helping the air conditioner maintain a relatively stable humidity level and improve the refrigeration efficiency. At the same time, the bottom end of the support plate 26 is fixedly connected to the bottom of the air conditioner cabinet 11. A synchronous belt assembly 23 is provided on the side of the pump body 24 away from the shielding frame 25. The penetrating end of the connecting shaft of one synchronous pulley in the synchronous belt assembly 23 is located at the center of the circular groove 213. The connecting shaft of the other synchronous pulley in the synchronous belt assembly 23 is rotatably connected through the support plate 26, and the penetrating end of the connecting shaft of the other synchronous pulley in the synchronous belt assembly 23 is fixedly connected to the first fan 27. The connecting shaft of one synchronous pulley in the synchronous belt assembly 23 is rotatably connected through the pump body 24.

[0038] As Figures 2 - 11As shown, at the same time, one end of the connecting shaft of a synchronous pulley in the synchronous belt assembly 23 is fixedly connected to the circular plate 215 in the pump body 24. One end of the shielding frame 25 is located at the notch 210 of the first fixing plate 28. The two sides of the first water tank 21 are fixedly connected through pipes 22, and the other end of the through pipe 22 is fixedly connected to the shielding frame 25 through penetration. At the same time, the penetrated end of the through pipe 22 is fixedly connected to the second water tank 29 through penetration. A pump body 24 is installed in the middle of the through pipe 22. Two slide rods 217 penetrate and slide on both sides of the pump body 24. One end of the slide rod 217 facing the circular plate 215 is welded with a slide plate 216. The slide plate 216 is located inside the pump body 24 and is slidably connected to it. One side of the slide plate 216 is fixedly connected to a spring 218. At the same time, the other end of the spring 218 is fixedly connected to the inner wall of the pump body 24. The slide rod 217 is located inside the spring 218. One end of the slide rod 217 facing the circular plate 215 is slidably connected to the circular plate 215. The inside of the through pipe 22 is communicated with the inside of the pump body 24. One end of the second fixing plate 212 is fixedly connected to the pump body 24 after passing through the shielding frame 25. The water curtain cooling not only reduces the inlet air temperature, but also enhances the air fluidity and improves the heat exchange effect of the air conditioner. By optimizing the air circulation, the air conditioner can absorb and release heat more efficiently, thereby enhancing the overall cooling effect. A circular groove 213 and two water tanks 214 are provided inside the pump body 24, and the two water tanks 214 coincide with the two end points of the circular groove 213. A circular plate 215 is rotatably connected to the center of the circular groove 213, and the center of the circular plate 215 does not coincide with the center of the circular groove 213. At the same time, the first water tank 21 is located at the center of the bottom of the air conditioner cabinet 11. One side of the first water tank 21 is fixedly connected through a water pipe 16 which is connected to the air conditioner cabinet 11 at the heat dissipation port 15. The compressor 19 and the humidifier 110 are installed on one side of the top surface of the pretreatment mechanism 2. Two water curtains can block the dust or pollutants in the external air inhaled by the air conditioning system, purify the air, and reduce the impact of the dust or pollutants in the air on the components inside the air conditioner.

[0039] As Figures 12 - 13As shown, a heat exchange mechanism 3 for reducing the cooling time of the machine room air conditioner is arranged on the top of the fan 18. The heat exchange mechanism 3 includes two first connecting plates 32 fixedly connected to the inside of the air-conditioning cabinet 11, and a second fan 31 is rotatably connected between the two first connecting plates 32. A U-shaped rod 33 is rotatably connected to the first connecting plate 32 away from the second fan 31, and the through end of the U-shaped rod 33 is fixedly connected to the second fan 31, and the other end of the U-shaped rod 33 is rotatably connected to the inner wall of the air-conditioning cabinet 11, a rotating plate 34 is rotatably connected to the middle part of the U-shaped rod 33, and the rotating plate 34 is rotatably connected to a metal strip 35 with a semi-arc structure at one end away from the U-shaped rod 33, and the two ends of the metal strip 35 are rotatably connected to second connecting plates 36, and the other end of the second connecting plate 36 is rotatably connected to a support frame 37. The shaking helps to remove pollutants accumulated on the surface of the evaporator 111 and reduce dust , oil and other substances, and reduce the risk of equipment failure caused by clogging of pollutants. Limit bars 38 fixedly connected to the inner wall of the air-conditioning cabinet 11 are arranged on both sides of the support frame 37, and the two limit bars 38 limit the support frame 37 laterally. At the same time, the support frame 37 is slidably connected to the limit bars 38. Evaporators 111 are installed on the top of several support frames 37. The evaporator 111 is connected to the condenser in the external unit after being passed through the air-conditioning cabinet 11 using a hose. The compressor 19 is similar. The refrigerant absorbs heat and evaporates in the evaporator 111 to reduce the temperature of the machine room. At the same time, the connection between the rotating plate 34 and the metal strip 35 is located in the middle of the metal strip 35. Air that has not flowed for a long time may cause corrosion on the surface of the evaporator 111. Especially when there is moisture in the machine room, appropriate elastic shaking can reduce the accumulation of moisture, reduce the risk of corrosion, and extend the service life of the evaporator 111.

[0040] The working principle of this embodiment is as follows. After the entire device is moved into the machine room, it is connected to the outdoor air-conditioning unit and powered on. Then, tap water is injected into the first water tank 21 through the water pipe 16. Then, the staff can operate the fan 18, compressor 19, humidifier 110 and other components in the air-conditioning cabinet 11 by operating the control panel 12, so that cold air is discharged from the air outlet 14 to cool the electronic equipment in the machine room. Then, the cold air is heated by the electronic equipment in the machine room to form hot air, which enters the air-conditioning cabinet 11 from the return air outlet 13, thus realizing cyclic cooling.

[0041] When hot air enters the air conditioner cabinet 11 from the air return port 13, it drives the first fan 27 to rotate. The hot air enters the shielding frame 25, and the rotation of the first fan 27 drives the synchronous belt assemblies 23 on both sides to drive. As a result, the circular plate 215 in the pump body 24 rotates with the center of the circular groove 213 as the origin, thereby squeezing the sliding rods 217 on both sides. With the cooperation of the springs 218, the sliding rods 217 move back and forth in the pump body 24, and then the tap water in the first water tank 21 is pumped out. After passing through the through pipe 22 and the water tank 214 in the pump body 24, it enters the second water tank 29.

[0042] When the water level in the second water tank 29 continuously rises and overflows from the top of the second water tank 29, the tap water in the second water tank 29 moves towards the filter plates 211 on both sides. Then, under the action of gravity, it falls back into the first water tank 21 through the filter holes of the filter plates 211. In this way, a cycle is formed, thus forming two water curtains. The hot air is initially cooled when passing through the first water curtain, and then further cooled when passing through the second water curtain, reducing the temperature of the air entering the air conditioning system, thereby reducing the burden on the air conditioning system and helping the air conditioner to still work more efficiently at a higher ambient temperature, improving the refrigeration effect.

[0043] The air that has been cooled by the two water curtains passes through the inclined slope of the shielding frame 25, enters the top of the first fixing plate 28 through the notch 210, and then, under the action of the fan 18, continuously moves upward. After being cooled by the evaporator 111, cold air is formed and discharged from the air outlet 14 under the cooperation of the guide plate 17.

[0044] When the pre-treated air continues to move upward under the action of the fan 18, it can drive the second fan 31 to rotate, thereby driving the U-shaped rods 33 on both sides to rotate, prompting the rotating plate 34 to move up and down reciprocally. At the same time, the rotating plate 34 rotates relative to the U-shaped rods 33. Furthermore, the metal strip 35 connected to the other end of the rotating plate 34 rotates relative to the rotating plate 34 and moves up and down reciprocally following the rotating plate 34 while the rotating plate 34 rotates relative to the U-shaped rods 33, causing the metal strip 35 to vibrate up and down reciprocally. As a result, the top support frame 37 moves along the same trajectory between the two limit strips 38, and the evaporator 111 connected to the top moves synchronously with the support frame 37. Moreover, while the second connecting plate 36 moves synchronously with the metal strip 35, the second connecting plate 36 rotates relative to the support frame 37 and the metal strip 35 respectively. Through this slight vibration, the surface of the evaporator 111 will contact the air more evenly, thereby improving the efficiency of heat exchange, breaking the adhesion effect of the air layer, making the air flow more smoothly, and improving the cooling effect.

[0045] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
