Description

Technical Field

[0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular to an evaporative cooling system and a cooling method. Background Art

[0002] The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit. The air conditioner compressor is generally installed in the outdoor unit. The air conditioner compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the heat sink, and the refrigerant also changes from gas to liquid, and the pressure increases. In order to improve the overall cooling effect of the air conditioner, it is necessary to improve the heat dissipation efficiency of the compressor.

[0003] For example, patent application CN110398047A discloses an evaporative cooling system and control method, including an indirect cooling module, an evaporation module, a heat exchanger, an indoor air supply module, an outdoor air supply module, a first detection module and a control module. The indoor air supply module is used for conveying indoor air, and the outdoor air supply module is used for conveying outdoor air. The indirect cooling module is used for indirect contact between outdoor air and its cooling water for heat exchange, and the evaporation module is used for direct contact between outdoor air and its cooling water for heat exchange. The heat exchanger is used for indirect contact between indoor air and the outdoor air and the cooling water of the evaporation module respectively for heat exchange and then conveying the indoor air to the room. The first detection module is used for detecting outdoor temperature, and the control module is respectively connected to the indirect cooling module, the evaporation module and the first detection module for communication. The control module controls the opening and closing of the indirect cooling module and the evaporation module according to the temperature value detected by the first detection module.

[0004] Although the above technology can meet different usage environments, save energy, make full use of natural cooling sources, and achieve the purpose of saving water and electricity, in actual use, the water only flows out from top to bottom through the sprinkler head toward the outside of the heat exchanger, resulting in a large contact dead angle, which makes the heat dissipation uneven and affects the heat dissipation effect.

[0036] The beneficial effects of the present invention are as follows:

[0037] 1. The present invention provides a storage box, a spray plate and a connecting pipe. The water droplets condensed on the outside of the air conditioner evaporator enter the storage box through the connecting pipe and are sprayed toward the outside of the compressor body through the spray plate. A control pipe, a connecting plate and a tapered shaft are provided at the same time. The pressure in the storage box cavity is increased by a pressurizing mechanism to control the connecting plate to slide downward, and the spring is controlled to store elastic potential energy. The connecting plate slides downward to drive the tapered shaft to slide synchronously until the tapered section of the tapered shaft moves to the constriction of the control pipe. As the air pressure in the storage box cavity increases, when the spray plate discharges liquid, the water discharge speed of the spray plate can be increased, and the liquid is dispersed after impact so as to be in uniform contact with the heating part. At the same time, when the spray plate sprays water, the volume of the individual sprayed water droplets can be reduced by high pressure. After the water droplets contact the heating part of the compressor body, the evaporation speed of the water droplets is increased, thereby improving the working efficiency of the compressor body.

[0038] 2. The present invention arranges a buoyancy plate, and an inclined pressure block is arranged outside the buoyancy plate. A limit hook is installed inside the storage box through a torsion spring. When the connecting plate slides downward, the limit hook is pushed open. As the connecting plate continues to slide, the limit hook engages with the connecting plate. At this time, the conical section of the tapered shaft is located at the shrinkage of the control tube, and the inner cavity of the storage box begins to discharge liquid. When the control tube drains water, the liquid level in the inner cavity of the storage box gradually decreases, the buoyancy block gradually decreases, and the inclined outer wall of the inclined pressure block presses the limit hook until the limit hook is separated from the connecting plate. At this time, the spring releases its elastic potential energy, controls the tapered shaft to seal the control tube, and after the boost pump is turned off, the storage box starts to store water again, thereby realizing the circulating water storage of the storage box and maintaining the heat dissipation efficiency of the compressor.

DETAILED DESCRIPTION

[0053] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0054] like Figures 1 to 11 As shown, an evaporative cooling system described in the present invention includes a compressor body 1, a liquid supply mechanism, a boosting mechanism, a control mechanism, a heat exchange mechanism and a climbing mechanism, wherein the compressor body extracts refrigerant from a low-pressure area, compresses it and sends it to a high-pressure area for cooling and condensation, and dissipates heat into the air through heat sinks.

[0055] The liquid supply mechanism includes a storage box 5, a spray plate 4 and a connecting pipe 2. The water droplets condensed on the outside of the air-conditioning evaporator enter the storage box 5 through the connecting pipe 2 and are discharged through the spray plate 4. The storage box 5 is arranged on the outside of the compressor body 1, and the spray plate 4 is arranged at the bottom of the storage box 5. After the inner cavity of the storage box 5 collects the water droplets, they are discharged through the spray plate 4. The water droplets flow along the outside of the compressor body 1, thereby improving the heat dissipation efficiency of the compressor body 1, and then improving the working efficiency of the compressor body 1.

[0056] The control mechanism includes a control tube 15 , a connecting plate 11 and a tapered shaft 14 . The control tube 15 is fixedly mounted on the bottom of the storage box 5 and one end of the control tube is connected to the spray plate 4 . The storage box 5 and the spray plate 4 are connected via the control tube 15 .

[0057] The conical shaft 14 is slidably installed in the inner cavity of the control tube 15, and the bottom of the connecting plate 11 is fixedly connected to the upper end of the conical shaft 14, wherein the bottom of the conical shaft 14 is a cylinder and the top is a cone, and a necking is provided on the top of the control tube 15. When the conical shaft 14 slides to the point where the cylindrical section fits with the necking, the inner cavity of the control tube 15 is closed, and when the conical shaft 14 slides to the point where the conical section is located at the necking, the inner cavity of the control tube 15 is connected, and at this time, the liquid in the inner cavity of the storage box 5 flows to the spray plate 4 through the control tube 15.

[0058] The bottom of the connecting plate 11 is elastically connected to the upper end of the control tube 15 through a spring. The pressure in the inner cavity of the storage box 5 is increased through a booster mechanism to control the connecting plate 11 to slide downward, and the spring is controlled to store elastic potential energy. The connecting plate 11 slides downward to drive the conical shaft 14 to slide synchronously until the conical section of the conical shaft 14 moves to the neck of the control tube 15. At this time, the spring is in a compressed state, thereby storing elastic potential energy.

[0059] As the air pressure in the inner cavity of the storage box 5 increases, the water drainage speed of the spray plate 4 can be increased when the spray plate 4 discharges liquid. At the same time, when the spray plate 4 sprays water, the volume of the individual sprayed water droplets can be reduced by high pressure. After the water droplets come into contact with the heating parts of the compressor body 1, the evaporation speed of the water droplets is increased, thereby improving the working efficiency of the compressor body 1.

[0060] It should be noted that when increasing the air pressure in the inner cavity of the storage box 5 , it is necessary to disconnect the connection between the connecting pipe 2 and the storage box 5 to prevent the internal air pressure of the storage box 5 from increasing and causing water backflow in the connecting pipe 2 .

[0061] The release of the elastic potential energy of the spring is controlled by the liquid level height in the inner cavity of the storage box 5. After the inner cavity of the control tube 15 is connected, the liquid inside the storage box 5 is discharged. At this time, the liquid level inside the storage box 5 gradually decreases. As the liquid level in the storage box 5 decreases to the desired position, the control spring releases the elastic potential energy, thereby controlling the connecting plate 11 and the tapered shaft 14 to reset until the tapered shaft 14 closes the control tube 15, so that the storage box 5 can store water again.

[0062] In this embodiment, the liquid level is used as a signal to trigger the resetting of the tapered shaft 14, so that the resetting time of the tapered shaft 14 can be prolonged in actual use, thereby ensuring that the spray plate 4 has sufficient time for drainage and spraying.

[0063] The heat exchange mechanism includes a storage cylinder 6 and a heat exchange plate 21. The storage cylinder 6 is arranged on the outer wall of the compressor body 1, and the heat exchange plate 21 is arranged in the storage cylinder 6. The heat exchange plate 21 is a copper plate and is in contact with the outer shell of the compressor body 1. The storage cylinder 6 is used to store the water flow left along the outer shell of the compressor body 1.

[0064] The bottom of the spray plate 4 is provided with an inclined hole facing the heat exchange plate 21. The water sprayed from the spray plate 4 evaporates on the outer wall of the heat exchange plate 21, absorbing the heat of the outer wall of the heat exchange plate 21, thereby improving the working efficiency of the compressor and improving the refrigeration effect.

[0065] The climbing mechanism is used to control the liquid in the inner cavity of the storage tube 6 to climb upward along the outer wall of the heat exchange plate 21. The climbing mechanism is used to control the liquid in the inner cavity of the storage tube 6 to climb to the upper end of the heat exchange plate 21 when the spray plate 4 stops spraying water, and then flow downward along the outer wall of the heat exchange plate 21, thereby maintaining the heat dissipation efficiency of the heat exchange plate 21 to the compressor body 1.

[0066] As a preferred embodiment of the present invention, the boosting mechanism includes a boosting pump 3 and a three-way valve, one of the output ends of the three-way valve is connected to the input end of the connecting pipe 2, the input end of the three-way valve is connected to the condensed water droplet collection chamber of the evaporator, and the other output end of the three-way valve is connected to a hose, and the other end of the hose leads to the outside of the air conditioner outdoor unit.

[0067] When the storage box 5 stores water, the three-way valve controls the evaporator condensation water droplet collection chamber to be connected with the storage box 5. When the inner cavity of the storage box 5 is pressurized, the three-way valve controls the evaporator condensation water droplet collection chamber to be connected with the hose to maintain normal drainage of the evaporator condensation water droplet collection chamber.

[0068] In this embodiment, the evaporator condensation water droplet collection chamber is a common structure for collecting water droplets in air-conditioning systems (not shown in the figure), which is a technical means well known to those skilled in the art and will not be described in detail here.

[0069] The booster pump 3 is fixedly mounted on the upper end surface of the storage box 5, and the output end of the booster pump 3 extends to the inner cavity of the storage box 5. The booster pump 3 is used to increase the air pressure in the inner cavity of the storage box 5 when the inner cavity of the storage box 5 is closed.

[0070] As a preferred embodiment of the present invention, the climbing mechanism includes a guide layer 23, a guide pipe 22, a control plug 29 and a drainage hole 31. A plurality of heat exchange plates 21 are evenly arranged along the outer wall of the compressor body 1. The guide layer 23 is arranged between two adjacent heat exchange plates 21, wherein the guide layer 23 is a common sponge, and one end of the guide layer 23 extends below the liquid level in the inner cavity of the storage cylinder 6. When the storage cylinder 6 stores water, the liquid is controlled to climb in the guide layer 23 by capillary action, thereby facilitating the upper end of the heat exchange plate 21 to contact with water.

[0071] The guide tube 22 is fixedly installed inside the guide layer 23, and the drainage hole 31 is obliquely opened on the outer wall of the guide tube 22 to control the pressure inside the guide tube 22, so that the liquid inside the storage tube 6 enters the guide tube 22 and is discharged from the drainage hole 31 to the inside of the guide layer 23, so that the upper end of the guide layer 23 absorbs moisture.

[0072] The control plug 29 is slidably installed in the inner cavity of the guide tube 22 . The pressure in the inner cavity of the guide tube 22 is controlled by the reciprocating sliding of the control plug 29 . The outer wall of the control plug 29 is sealed and fitted with the inner wall of the guide tube 22 .

[0073] An exhaust fan 7 is fixedly installed on the outer wall of the storage cylinder 6. The exhaust fan 7 exhausts toward the side away from the compressor body 1. The exhaust fan 7 consists of a motor and fan blades, and is used to increase the air flow speed inside the storage cylinder 6, thereby increasing the evaporation speed of water droplets inside the storage cylinder 6, and further improving the heat dissipation efficiency of the compressor body 1.

[0074] In order to evenly exhaust the inner cavity of the storage cylinder 6 , a plurality of exhaust fans 7 are provided, and the plurality of exhaust fans 7 are evenly distributed in a ring shape along the axis of the storage cylinder 6 , so as to evenly exhaust the inner cavity of the storage cylinder 6 .

[0075] As a preferred embodiment of the present invention, a sealing ring 27 for sealing the drainage hole 31 is slidably installed in the inner cavity of the guide tube 22 , and the outer wall of the sealing ring 27 is slidably fitted with the inner wall of the guide tube 22 .

[0076] There are multiple blocking rings 27 and drainage holes 31 evenly arranged along the outer wall of the guide tube 22. A mesh plate 32 is fixedly installed in the inner cavity of the guide tube 22. A connecting rod 28 is elastically arranged at the bottom of the mesh plate 32. Multiple blocking rings 27 are connected by the connecting rod 28. The sliding connecting rod 28 controls the synchronous movement of multiple blocking rings 27.

[0077] The top of the connecting rod 28 is sealed against the inner wall of the guide tube 22, so that the sliding of the connecting rod 28 can be controlled by increasing the pressure in the inner cavity of the guide tube 22 to facilitate drainage of the drainage hole 31. After the drainage hole 31 is drained, the elastic force exerted on the connecting rod 28 controls multiple sealing rings 27 to synchronously block the drainage holes 31.

[0078] A guide plate 30 is fixedly installed on the inner wall of the guide tube 22. The guide plate 30 is located above the control plug 29, and a one-way valve for controlling the flow of liquid is arranged inside the guide plate 30. The guide plate 30 divides the inner cavity of the guide tube 22 into three chambers: upper, middle and lower.

[0079] The air pressure in the lowermost chamber of the inner cavity of the regulating guide tube 22 drives the control plug 29 to slide. The sliding of the control plug 29 controls the liquid in the middle chamber to flow into the upper chamber through the one-way valve inside the guide plate 30. As the hydraulic pressure of the upper chamber increases, the connecting rod 28 slides, driving the sealing ring 27 to slide until the drainage hole 31 is connected, so that the liquid in the upper chamber is discharged.

[0080] A feed pipe 24 is fixedly installed on the outer wall of the guide pipe 22, one end of the feed pipe 24 extends below the liquid level in the inner cavity of the storage cylinder 6, and the liquid in the inner cavity of the feed pipe 24 flows unidirectionally. A one-way valve is arranged inside the feed pipe 24 to control the liquid in the inner cavity of the storage box 5 to enter the middle chamber of the guide pipe 22, and the water is discharged to the upper chamber of the guide pipe 22 by reciprocating sliding of the control plug 29.

[0081] It should be noted in this embodiment that the air in the middle and upper chambers of the guide tube 22 needs to be exhausted before use to prevent the air from affecting the drainage of the drainage hole 31 located at the top.

[0082] In addition, by controlling the synchronous movement of the plurality of blocking rings 27 and the synchronous drainage of the plurality of drainage holes 31 , the water guide layer 23 can absorb water uniformly.

[0083] As a preferred embodiment of the present invention, a connecting ring 10 is provided on the outside of the storage tube 6. The connecting ring 10 is a hollow structure. A transfer tube 25 is fixedly installed on the outer wall of the connecting ring 10. The inner cavity of the transfer tube 25 is connected to the inner cavity of the connecting ring 10. One end of the transfer tube 25 extends from the inner cavity of the storage tube 6 and is connected to the bottom of the guide tube 22. The connection between the lowermost chamber of the inner cavity of the guide tube 22 and the inner cavity of the connecting ring 10 is achieved through the transfer tube 25.

[0084] A control cylinder 8 is fixedly mounted on the outer wall of the connecting ring 10 , a sliding plug 26 is slidably mounted in the inner cavity of the control cylinder 8 , and a control rod 9 is fixedly mounted on the outer wall of the control cylinder 8 , and the control rod 9 is a common electric telescopic rod.

[0085] The movable end of the control rod 9 is fixedly connected to the outer wall of the sliding plug 26. The control rod 9 controls the sliding plug 26 to slide back and forth along the inner cavity of the control tube 8, thereby adjusting the air pressure in the lowermost chamber of the inner cavity of the guide tube 22, driving the control plug 29 to slide back and forth, serving as the power for the liquid to climb.

[0086] As a preferred embodiment of the present invention, a mounting cylinder 13 is fixedly installed at the bottom of the storage box 5, and an adjusting plug 16 is fixedly installed in the inner cavity of the mounting cylinder 13. The top of the adjusting plug 16 is fixedly connected to the connecting plate 11. The adjusting plug 16 is a rubber plug. The connection between the external air and the inner cavity of the storage box 5 is achieved through the mounting cylinder 13. As the air pressure in the inner cavity of the storage box 5 increases, the adjusting plug 16 slides. At this time, the adjusting plug 16 drives the tapered shaft 14 to slide synchronously through the connecting plate 11.

[0087] The bottom surface of the storage box 5 is elastically mounted with a limit hook 20 for engaging with the outer wall of the connecting plate 11 through a bracket. The bracket is fixedly connected to the bottom of the storage box 5, and the middle part of the limit hook 20 is directly connected to the outer wall of the connecting plate 11 through a torsion spring.

[0088] When the connecting plate 11 slides downward, the limit hook 20 is pushed away. As the connecting plate 11 continues to slide, the limit hook 20 engages with the connecting plate 11. At this time, the conical section of the tapered shaft 14 is located at the contraction of the control tube 15. The inner cavity of the storage box 5 begins to discharge liquid, and the control tube 15 remains in a conductive state. At the same time, the spring at the bottom of the connecting plate 11 stores elastic potential energy due to the engagement of the limit hook 20 with the connecting plate 11.

[0089] A buoyancy block 12 is slidably installed in the inner cavity of the storage box 5. The height of the buoyancy block 12 is affected by the liquid level in the inner cavity of the storage box 5. The buoyancy block 12 is controlled to rise by buoyancy. A pressing inclined block 19 for pressing the limit hook 20 is fixedly installed on the side wall of the buoyancy block 12. When the control tube 15 is drained, the liquid level in the inner cavity of the storage box 5 gradually decreases, and the buoyancy block 12 gradually decreases until the inclined outer wall of the pressing inclined block 19 presses the limit hook 20 away from one end of the connecting plate 11, driving the limit hook 20 to deflect until the limit hook 20 is separated from the connecting plate 11. At this time, the spring releases its elastic potential energy, controls the conical shaft 14 to block the control tube 15, and after turning off the booster pump 3, the storage box 5 starts to store water again.

[0090] In order to increase the force of the top-pressing inclined block 19 and the top-pressing limit hook 20, a control block 17 is fixedly installed on the inner wall of the buoyancy block 12, and an attraction sheet 18 for attracting the control block 17 is fixedly installed on the inner wall of the storage box 5. The attraction sheet 18 is a magnet, and the control block 17 is an iron block. As the buoyancy block 12 descends, the attraction sheet 18 attracts the control block 17 through magnetic force, thereby increasing the force of the top-pressing inclined block 19 and the top-pressing limit hook 20, so as to trigger the spring to release elastic potential energy.

[0091] When the liquid completely submerges the buoyancy block 12, the buoyancy of the buoyancy block 12 and the control block 17 as a whole is F 浮 The maximum attraction of the attraction piece 18 to the control block 17 is F 吸 The overall weight of the buoyancy block 12 and the control block 17 is G 总 , the relationship between the three needs to satisfy F 浮 >F 吸 +G 总 , thereby ensuring that the buoyancy block 12 can rise again after the liquid in the inner cavity of the storage box 5 submerges the buoyancy block 12, so as to facilitate the reset of the limit hook 20 and prepare for the next engagement with the connecting plate 11.

[0092] like Fig.12 As shown, a cooling method of an evaporative cooling system, which is applied to the above-mentioned evaporative cooling system, comprises the following steps:

[0093] A1. Open the three-way valve to control the water droplets on the outer wall of the evaporator to flow into the inner cavity of the storage box 5 until the liquid level in the inner cavity of the storage box 5 reaches the required height;

[0094] A2, the inner cavity of the storage box 5 is closed by controlling the three-way valve, and after closing, the booster pump 3 is started to increase the air pressure in the inner cavity of the storage box 5;

[0095] A3. As the air pressure in the storage box 5 increases, the regulating plug 16 slides downward until the limit hook 20 engages with the connecting plate 11;

[0096] A4, the liquid in the storage box 5 is sprayed toward the heat exchange plate 21 through the spray plate 4, and the exhaust fan 7 is used to exhaust and dissipate heat;

[0097] A5. As the liquid level in the storage box 5 decreases, the buoyancy block 12 slides down and pushes the limit hook 20 to separate from the connecting plate 11 through the top pressure inclined block 19;

[0098] A6. The tapered shaft 14 is reset by the spring force, and then the booster pump 3 is turned off and the three-way valve is controlled to be connected to the inner cavity of the storage box 5 again.
