Description

Technical Field

[0001] This invention relates to an evaporative high-ambient-temperature energy-saving refrigeration unit. Background Technology

[0002] Evaporative self-circulating coolers place the heat exchanger on the side of the cooler housing. Flowing spray water cools the air within the packing fins, increasing its humidity to saturation. A fan then forces the saturated, humid air to exchange heat with the circulating fluid within the heat exchanger. The air, after heat exchange, is then vented back to the atmosphere by the fan. This ensures the effective cooling through heat exchange within the circulating fluid. Because the circulating fluid operates in a closed loop within the heat exchanger, it remains uncontaminated, protecting the main equipment and extending its lifespan. When the outside temperature is low, the spray water system can be shut off, maintaining the cooling effect through heat exchange with the circulating fluid within the pipes. This also prevents the spray water outside the pipes from freezing and cracking the cooler housing and spray pipes, thus saving water. Evaporative self-circulating cooler systems are suitable for use in harsh environments such as arid, water-scarce areas, and areas prone to sandstorms. It is widely used in various industries, including central air conditioning, instrumentation, medium-frequency electric furnaces and converters in metallurgy, generator sets and steam turbines in power plants, nuclear power plants and substations, chemical industry, pharmaceutical industry, welding, aluminum and copper foil cooling oil, and hydraulic oil for large hydraulic machinery.

[0003] Chinese Patent No. 202123422206.8 discloses an evaporative self-circulating cooler, including a body with an air inlet and an air outlet. From the air inlet to the air outlet, an air filter, a packing heat sink, a water collector, a heat exchanger, and a fan are arranged in sequence. The area between the water collector and the heat exchanger is called the evaporative heat exchange box, and the area between the heat exchanger and the fan is called the heat exchange box. A water storage tank is located at the bottom of the body. A spray pipe is located above the packing heat sink, and the spray pipe is equipped with downward spray heads. A spray water delivery pipe is connected between the water storage tank and the water inlet of the spray pipe. A spray pump is installed on the spray water delivery pipe. A self-priming pump is installed on the pipe at the inlet end of the heat exchanger. The water outlet on one side of the water storage tank is connected to the water inlet of the spray pipe through the spray water delivery pipe.

[0004] The evaporative self-circulating cooler disclosed in the above patent has the following defects:

[0005] 1. The spraying effect of the water spray is not good; the poor effect of traditional direct spraying is due to the original air inlet having a filter screen. In terms of filter screen selection, a high-density filter screen is selected, which is ideal for dust filtration, but the filter screen is easy to clog, which leads to a reduction in airflow. The air that is not cooled and the air with increased humidity do not exchange heat with the heat exchanger, resulting in a decrease in heat exchange performance or even no heat exchange. The reduced airflow also increases the static pressure of the fan, increasing the power of the fan and causing the fan motor to overload and burn out, which requires frequent cleaning of the filter screen dust.

[0006] 2. Traditional water collectors have poor water collection efficiency. Traditional water collectors are generally C-shaped, with concave openings stacked at a fixed interval at a 45-degree angle upwards towards the windward side. When the wind speed is high, the fast-moving humid air carrying water droplets is drawn into the traditional water collector plates. As the humid air passes through the plates, some water droplets are blocked. Due to the high wind speed and the narrowness of the traditional water collector, some droplets drift off the plates. Other droplets, due to gravity, drip onto the next layer of plates. A large portion of these droplets are carried out of the collector by the high-speed airflow, resulting in a high drift rate and significant water waste. Increasing the angle of the stacked plates can reduce the drift rate and improve the water collection efficiency, but this will obstruct the airflow, increasing the static pressure of the fan, reducing the fan volume, potentially overloading the fan, or requiring an increase in fan power and power consumption. Increasing the number of water collectors and combining them will increase costs and volume, but there will still be a certain amount of water drift, and the desired water collection effect will not be achieved.

[0007] 3. Currently, high-ambient-temperature refrigeration machines on the market can only maximize the increase of the compressor condenser, increase the exhaust volume of the condenser, reduce the heat absorption of the evaporator, and operate on the principle of the refrigeration system injecting refrigerant into the compressor. This results in high energy consumption and extremely low energy efficiency ratio, even below 1. Summary of the Invention

[0008] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an evaporative high-ambient-temperature energy-saving refrigeration machine with good cooling effect and high energy efficiency ratio.

[0009] The objective of this invention is achieved as follows:

[0010] An evaporative high-ambient-temperature energy-saving refrigeration unit and an evaporative self-circulating cooler are disclosed, comprising a body with an air inlet and an air outlet.

As a preferred embodiment, two or more guide holes are provided on the first inclined surface, and two or more guide holes are also provided on the second inclined surface.

[0017] As a preferred embodiment, the water collector is a centrally rotating water collector with adjustable tilt. A fixed support is provided in the middle of the water collector. The fixed support includes multiple fixed sleeves, multiple connecting rods, and a central adjusting rod. The fixed sleeves are fitted into the middle sections of multiple lead screws.

The fixed support allows the angle of the entire water collector to be controlled by adjusting the rotation of the central adjusting rod.

[0018] As a preferred embodiment, the water collector is a splash-proof, water-containing, and air-adjustable water collector. A movable water-collecting plate is hinged to the high-end free end of the first inclined surface, i.e., the low end of the first inclined surface.

[0019] As a preferred embodiment, the water storage tank is equipped with multiple filter partitions inside, which divide the water storage tank into a sedimentation tank, a water filtration tank, and a clear water tank.

[0020] As a preferred embodiment, the water filter box is located directly below the packing heat sink, and the sedimentation box and the clear water box are located on both sides of the water filter box and are connected to each other. The sedimentation box and the clear water box are respectively arranged opposite each other on one side of the air inlet and air outlet of the unit.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The advantages of combining water curtain and spray systems are:

[0023] 1.1 Integrated Design: The water curtain and spray systems are combined and can share a single water pump. This allows for constant water pressure and maximizes the control of each spray effect. The unique design of the water curtain nozzles ensures both the generation and use of the water curtain while maintaining constant water pressure. The optimized structure reduces costs, and the integrated design optimizes the size of the equipment and makes scientific and rational use of water pump resources.

[0024] 1.2 Constant Pressure Adjustable Water Curtain: The flow rate and pressure of the water in the water curtain and the spray can be controlled. Water is delivered to the spray tank through the spray pipe. Since the spray heads require a certain water pressure to achieve complete atomization, the water in the spray tank maintains a constant pressure, ensuring pressure equalization and achieving optimal atomization. The water in the constant pressure spray tank enters through a flow regulating plate with a multi-hole design, ensuring pressure equalization in the water curtain tank and consequently, pressure equalization in the water curtain nozzles. This allows for a uniform and consistent water curtain spray. The flow regulating plate adjusts the water volume and flow rate to prevent dust from entering the heat sink fins.

[0025] 1.3 Humidification and Cooling Effect of Water Curtain Drainage Plate: When the appropriate water volume of the water curtain and the high-speed air pass through the staggered holes on the water curtain drainage plate, negative air pressure backflow, void effect, and bubble effect are generated between the water curtain drainage plates. The void effect is conducive to adsorbing dust, and the bursting of bubbles in the bubble effect helps the water atomize, making the atomized water more integrated into the airflow. The vaporization of water absorbs heat from the air, reducing the temperature of the moving humid air. Through the above-mentioned spraying, vaporization, adsorption, and humidification effects, the air becomes clean, saturated, and cool.

[0026] 1.4. Dust Isolation Function of the Water Curtain Diverter Plate: The water curtain sprayed from the water curtain diverter plate efficiently isolates and adsorbs dust particles in the high-speed airflow. The staggered holes on the water curtain diverter plate divide the high-speed airflow into several smaller airflows, which can then adsorb dust particles again. When the airflow passes through the staggered holes on the water curtain diverter plate again, it adsorbs dust particles for a third time. During this process, the adsorption of dust particles in the airflow is maximized through multiple void effects and bubble effects. The dust adsorbed in the water flows to the sedimentation tank through the water curtain diverter plate and gravity, preventing dust from entering the heat sink fins.

[0027] 1.5 The water collection effect of the two superimposed water curtain diversion plates: The air drawn in from the right side is adsorbed by the water curtain on the right side to absorb dust in the airflow and increase the humidity of the air. Then, after passing through the filler heat sink, the humidity of the air is further increased to wet saturated air and supersaturated humid air. The humidified wet saturated air and supersaturated humid air enter the water curtain on the left side, thereby separating the condensed water droplets from the humid air. Through the treatment of the water curtain and water curtain plate, the hydrophilic fusion characteristics of water make the condensed water droplets with excessive moisture content separate from the humid air.

[0028] 2. The new type of water collector has the following advantages:

[0029] 2.1 The S-shaped water-collecting plate design, which follows the wind direction, increases the contact area with flowing air, resulting in low wind resistance. The first and second inclined surfaces on both sides of the windward water-collecting plate have small angles. Guide holes are arranged on the first inclined surface, and the inclined section connecting them has an angle twice that of the first inclined surface. This allows some of the water droplets formed in the saturated air to be absorbed and released on the first inclined surface when it comes into contact with the flowing air. As it passes through the inclined section, the water droplets are squeezed out again and discharged downwards through the guide holes on the first inclined surface. Because the guide holes on the first inclined surface guide the flowing air, the water droplets discharged downwards are quickly sprayed downwards. This maximizes the control of water drift and saves water resources. The smaller angle of the second inclined surface allows for rapid release and guidance of saturated air.

[0030] 2.2 The water collector is made by stacking individual water-collecting plates. The length and height can be customized according to process requirements. It is convenient and simple to manufacture. It is small in size and easy to install.

[0031] 2.3 The water collector is equipped with a connecting rod. The rotation angle of the water collector can be adjusted by adjusting the central adjusting rod from the outside, so as to adjust the water waste rate and wind pressure value according to the actual process requirements and wind speed requirements.

[0032] 2.4 Movable Water Collector: A newly designed movable water collector is installed on the water collection plate. The water consumption rate and wind pressure are adjusted according to actual process requirements and wind speed requirements via the first adjusting chain, second adjusting chain, and adjusting screw. Flowing humid saturated air and water droplets formed in the air pass through the movable water collector. The movable inclined plate exerts a face-to-face pressure on the water droplets, releasing them and separating them from the humid saturated air. The water droplets fall downwards into the water storage tank due to gravity. The flowing humid saturated air then passes through the movable water collector and the first inclined water collector. The movable water collector and the first inclined water collector have a certain angle. When the flowing humid saturated air passes through this angle, a micro-circulation negative pressure return chamber is formed inside the angle. The water droplets and water droplets carrying the humid saturated air separate in the negative pressure return chamber and are discharged downwards through the guide holes of the water collector. When the flowing humid saturated air passes through the inclined section, the inclined section will compress the water droplets formed by the flowing humid saturated air, and the water droplets will be released again and discharged downward through the guide holes on the first inclined surface.

[0033] 3. The evaporative high-ambient-temperature energy-saving refrigerator is a new type of refrigerator formed by replacing the heat exchanger with a condenser on the basis of an evaporative self-circulating chiller, and adding a compressor and evaporator. It is used in environments where the ambient temperature is higher than that of ordinary refrigerators, which cannot operate safely. The ambient temperature is generally above 40℃, and can even reach 60℃. By using the principle of humidifying saturated air with water and then adding water to absorb heat through evaporation, the refrigerant temperature of the compressor condenser of the evaporative high-ambient-temperature energy-saving refrigerator is very close to the ambient temperature, or even lower than the ambient temperature. The cooled refrigerant enters the evaporator, which can maximize the absorption of heat from the cooled liquid without causing high refrigerant superheat or high return gas temperature, thus ensuring the safe operation of the refrigerator. This maximizes the cooling capacity and also increases the energy efficiency ratio of the refrigerator, which can reach 3 or higher, achieving the goal of energy saving. This evaporative high-ambient-temperature energy-saving refrigerator can automatically shut off the water humidification mode when the ambient temperature is normal or low, and can operate around the clock.

[0034] In summary, the present invention has the advantages of good cooling effect and high energy efficiency ratio. Attached Figure Description

[0087] 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 a part of the embodiments of the invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0088] Referring to the accompanying drawings, the present invention relates to an evaporative self-circulating cooler, comprising a body 101, wherein the body 101 is provided with an air inlet and an air outlet, and from the air inlet to the air outlet are sequentially arranged an air inlet filter 102, a packing heat exchanger 103, a water collector 104, a heat exchanger 105, and a fan 106. The area between the water collector 104 and the heat exchanger 105 is called the evaporative heat exchange box, and the area between the heat exchanger 105 and the fan 106 is called the heat exchange box. A water storage tank 108 is provided at the bottom of the body 101. A spray device 107 is installed above the unit 3, with downward-facing spray heads. A spray water delivery pipe 109 connects the water storage tank 108 to the inlet of the spray device 107, and a spray pump 112 is installed on the spray water delivery pipe 109. The water storage tank 108 is used for storing circulating water and contains an automatic water adder 108.5, a water filter 108.6, a sensor, and an electric heating element. The outlet on one side of the water storage tank 108 is connected to the inlet of the spray device 107 via the spray water delivery pipe 109. A circulation pump 100 is installed on the pipe at the inlet end of the heat exchanger 105, and the circulation pump 100 is housed in a box. The circulation pump box is the same height as the water storage tank 108. The heat exchanger 105 can be straight, V-shaped, H-shaped, or other forms, and the air outlet can be located on the side or top of the unit.

[0089] The heat transfer medium within the heat source of the equipment circulates with the heat transfer medium tank, thereby cooling the heat source. Conversely, the heat transfer medium in the heat transfer medium tank circulates back to the heat exchanger of the evaporative self-circulating cooler, where it is cooled again before returning to the heat transfer medium tank. Within the evaporative self-circulating cooler, the heat exchanger is cooled by air. The air cooling method involves air entering through the air inlet, passing sequentially through the air inlet filter, packing fins, water collector, heat exchanger, and fan, before exiting through the air outlet. During this process, the air is cooled, humidified, and dust-removed by water sprayed from a spray device. The water for the spray device is supplied by a water storage tank, and the water that falls from the spray is collected in the water storage tank.

[0090] The spraying device 107 can take various forms:

[0091] Form 1: The spray device 107 is an integrated spray double water curtain generator.

[0092] An integrated dual-water curtain spraying device includes a spray water collection tank 107.1, with a water curtain collection tank 107.2 connected to each end of the spray water collection tank 107.1. A water curtain guide plate 110 is positioned directly below each of the two water curtain collection tanks 107.2, located on one side of the air inlet and the other side of the air outlet of the packing heat sink 103. A fixed flow channel is provided between the water curtain collection tanks 107.2 and the spray water collection tank 107.1. A flow regulating plate 107.3 is attached to one side of the fixed flow plate 107.3. Both the fixed flow plate 107.3 and the adjacent flow regulating plate 107.4 are provided with multiple flow regulating holes 107.41 arranged along the length direction. The flow regulating holes are preferably oval in shape. One end of the flow regulating plate 107.4 is provided with an adjusting plate screw 107.5. The flow regulating plate 107.4 and the fixed flow plate 107.4 are adjusted by controlling the adjusting plate screw 107.5. The relative positions of 7.3 are adjusted to regulate the misalignment of the flow regulating holes between the two plates, thereby adjusting the amount of water supplied from the spray water collection tank 107.1 to the water curtain water collection tank 107.2. The spray water collection tank 107.1 is equipped with a spray water collection tank inlet, which is connected to the spray water delivery pipe 109. The bottom of the spray water collection tank 107.1 is equipped with a spray head connection hole 107.11, which is used for the detachable installation of a spray head 107.12. 107.11 is preferably threaded. The bottom of the water curtain collecting tank 107.2 is provided with a water curtain nozzle 107.21. The water curtain nozzle 107.21 is provided with an elongated inner channel. The inner channel has the following structure: the length of the inner channel from the upper plane to the lower plane of the water curtain nozzle 107.21 remains unchanged, and the width narrows inward in a trapezoidal structure, forming a vertical constriction section at one-third of the total height. The constriction section has the function of collecting water, so that the sprayed water will not scatter and effectively filter dust in the air. The water curtain diversion plate 110 includes multiple water curtain diversion panels 110.1, which are connected by fixing bolts 110.2. Spacing sleeves 110.3 are fitted onto the fixing bolts 110.2 between two adjacent water curtain diversion panels 110.1. Hexagonal air guide holes 110.11 are provided on the water curtain diversion panels 110.1. Fixing bolts 110.2 are inserted into the mounting holes 110.4 at the four corners and the two sides of the middle of the water curtain diversion panels 110.1. The air guide holes 110.11 between two adjacent water curtain diversion panels 110.1 are staggered. When the air containing dust passes through the water curtain diversion plate 110, it is humidified and dust-removed by the water curtain sprayed down by the water curtain nozzles 107.21 above. The air flowing out of the water curtain diversion plate 110 is clean and humidified air.

[0093] Working principle and function of integrated spray double water curtain generator:

[0094] Water enters the spray tank to meet the required spray volume. The spray heads can be installed on threaded spray head connection holes and are detachable. The flow regulating plate controls the effective orifice area through which the fluid passes by by means of parallel and staggered alignment with the fixed flow plate. By adjusting the area of ​​the effective orifice, the water flow rate is controlled, ensuring that the overall water flow is evenly and uniformly distributed within the water curtain tank. The water flow within the tank is minimally disturbed or turbulent, resulting in a more uniform and balanced water curtain spray without any water spraying or splashing.

[0095] The water curtain box on the right generates a water curtain to filter and flush the dust and dirt in the air entering the evaporative self-circulating cooler, thus purifying the air.

[0096] The water curtain box on the left generates a water curtain to separate the condensed water and air caused by excessive moisture from the humidified packing heat sink. Through the water curtain's treatment, the hydrophilic and fusion properties of water allow the excessive moisture content of the condensed water droplets to be separated from the humid air.

[0097] Water curtain guide plates can be used individually or stacked in multiple pieces. When multiple plates are stacked, they are arranged at a certain interval. The water sprayed down vertically cuts the air, forming a complete water curtain. When air passes through the water curtain, dust and particulate matter in the air are adsorbed and filtered by the water curtain. Some air impacts the water curtain, causing it to adhere to the entire guide plate and flow downwards. At this time, the air flows through the air guide holes, creating a bubble effect, increasing the contact area between air and water, increasing air humidity, and generating air turbulence. The water curtain guide plate has hexagonal holes, which helps to generate the bubble effect.

[0098] Form 2: The spray device 107 is an integrated spray single water curtain generator.

[0099] The difference between Form 2 and Form 1 is that a water curtain guide plate 110 is provided only on one side of the air inlet of the packing heat sink 103, and a water curtain collection tank 107.2 is located above the water curtain guide plate 110.

[0100] Form 3: The spray device 107 is a split-type spray water curtain generator.

[0101] The difference between Form 3 and Form 2 is that the water curtain collection tank 107.2 exists independently and is directly supplied with water by the spray water delivery pipe 109. The setting of the spray water collection tank 107.1 is cancelled and replaced by multiple spray pipes 111 arranged in parallel. The multiple spray pipes 111 are directly connected to the spray water delivery pipe 109. If necessary, a water curtain diversion plate 110 can be set on one side of the air inlet and air outlet of the packing heat sink 103, and the water curtain collection tank 107.2 is set above the corresponding water curtain diversion plate 110.

[0102] The water collector 104 includes multiple water collecting plates 104.1 arranged at equal intervals from top to bottom. The water collecting plates 104.1 are connected by screw rods 104.2. A support sleeve 104.4 is provided outside the screw rod 104.2 between two upper and lower water collecting plates 104.1. The support sleeve 104.4 can be integrally stamped with the water collecting plate 104.1 or it can be a separate sleeve. The water collecting plate 104.1 is arranged sequentially from the air outlet side to the air outlet side as a first inclined surface 104.11, an inclined section 104.12, and a second inclined surface 104.13. The first inclined surface 104.11... 04.11 is parallel to the second inclined surface 104.13. The inclined section 104.12 is at an obtuse angle to both the first inclined surface 104.11 and the second inclined surface 104.13. The slope of the inclined section 104.12 is greater than the slopes of the first inclined surface 104.11 and the second inclined surface 104.13. The first inclined surface 104.11 is provided with a plurality of arrayed guide holes 104.14. Preferably, two or more 104.2 are passed through the first inclined surface 104.11, and two or more 104.2 are also passed through the second inclined surface 104.13.

[0103] As a preferred first option, the water collector 104 can be upgraded to a water collector with a centrally rotating tilt that can change its inclination. A fixed support 104.3 is provided in the middle of the water collector 104. The fixed support 104.3 includes multiple fixed sleeves 104.31, multiple connecting rods 104.32, and a central adjusting rod 104.33. The fixed sleeves 104.31 are fitted into the middle sections of multiple lead screws 104.2. The connecting rods 104.32 connect the fixed sleeves 104.31 at the same lateral position. A central adjusting rod 104.33 passes through multiple connecting rods 104.32 to form the fixed support 104.3. The fixed support 104.3 allows the angle of the entire water collector 104 to be controlled by adjusting the rotation of the central adjusting rod 104.33, which is convenient for collecting water vapor at different wind speeds.

[0104] The working principle and function of a tilt-adjustable water collector: The water-collecting plate is fixed at a certain angle. The installed water collector is also fixed at a certain angle. With the center adjustment rod installed, it can be adjusted clockwise or counterclockwise. Rotating the water collector clockwise increases the water-collecting angle, resulting in better water collection but also increased wind resistance; rotating the water collector counterclockwise decreases the water-collecting angle, resulting in poorer water collection but less wind resistance.

[0105] As a second preferred option, the water collector 104 can also be upgraded to a splash-proof water collector with adjustable moisture and air content. A movable water collector 104.5 is hinged to the high-end free end of the first inclined surface 104.11, i.e., the low end of the first inclined surface 104.11. The width of the movable water collector 104.5 is the same as the width of the first inclined surface 104.11. The movable water collector 104.5 is provided with a movable water collector guide hole 104.51. A movable water collector positioning connection hole 104.53 is provided on the edge of the movable water collector 104.5. A first inclined surface positioning connection hole 104.54 is provided on the edge of the first inclined surface 104.11. The movable water collector 104.53 and the first inclined surface positioning connection hole 104.54 are staggered. The movable water collector 104.5 and the first inclined surface... Preferably, surface 104.11 is hinged to the first inclined surface positioning connection hole 104.54 by a connecting rod positioning pin 104.52 passing through the positioning connection hole 104.53 of the movable water-collecting plate and ending with a clamp 104.55. Each of the free ends of the multiple movable water-collecting plates 104.5 is provided with a connecting rod positioning hole. A movable water-collecting plate connecting rod 104.6 connects the connecting rod positioning holes of the multiple movable water-collecting plates 104.5. A first adjusting chain rod 104.7 is rotatably connected to the middle of the movable water-collecting plate connecting rod 104.6. The first adjusting chain rod 104.7 and the second adjusting chain rod 104.8 are connected by a movable pin. The second adjusting chain rod 104.8 is rotatably connected to the fixed base. The angle of the movable water-collecting plate 104.5 can be adjusted by the adjusting screw 104.9 at the end of the second adjusting chain rod 104.8.

[0106] The working principle and function of a splash-proof, moisture-containing adjustable water collector: Adjusting the direction of the movable water collector plate changes the angle between the movable water collector plate and the first inclined plane, creating a swirling cavity within the angle. When air with excessive moisture content and condensation passes through this swirling cavity, due to the influence of swirling force, swirling negative pressure, and gravity, the excessive moisture content and condensation separate from the air. The humid air rises through the water collector, while the condensation droplets are discharged through the guide holes. The larger the angle, the greater the swirling force and swirling negative pressure, resulting in better water collection; the smaller the angle, the smaller the swirling force and swirling negative pressure, resulting in poor water collection. Adjusting the movable water collector plate can compensate for the shortcomings of traditional water collectors, such as poor water collection and high wind resistance under high airflow and high air velocity conditions, allowing for precise adjustment of the water collection effect.

[0107] The water storage tank 108 is internally equipped with multiple filter partitions 108.1, which divide the water storage tank 108 into a sedimentation tank 108.2, a water filtration tank 108.3, and a clean water tank 108.4. The water filtration tank 108.3 is located directly below the packing heat sink 103. The sedimentation tank 108.2 and the clean water tank 108.4 are located on both sides of the water filtration tank 108.3 and are connected to each other. The sedimentation tank 108.2 and the clean water tank 108.4 are respectively arranged opposite each other on one side of the air inlet and air outlet of the machine body.

[0108] The water collected in the sedimentation tank is mainly used by the water curtain box to filter and flush the dust and dirt in the air entering the evaporative self-circulating cooler. The water containing dust and dirt then flows to the sedimentation tank for sedimentation, and the water passes through the filter baffle to the water filter box, and then through the filter baffle to the clear water tank.

[0109] The water collected in the water filter box is water sprayed from the spray pipe, and then passes through the packing heat sink and air heat exchange to increase the moisture content in the air.

[0110] The water collected in the clean water tank is water received from the water collector and water from the automatic water replenisher.

[0111] As an optimization, improvements are made to the evaporative self-circulating cooler to create an evaporative high-ambient-temperature energy-saving refrigerator. The evaporative high-ambient-temperature energy-saving refrigerator also includes an evaporator 200 and a condenser 203. The condenser 200 replaces the heat exchanger 105, and they are arranged side-by-side without obstruction on one side of the air inlet of the fan 106. The heat transfer medium in the heat transfer medium tank circulates to the evaporator 200 of the evaporative self-circulating cooler for cooling. A gas-liquid separator 201 and a compressor 202 are sequentially installed on the pipeline between the inlet of the evaporator 200 and the condenser 203. A liquid receiver 204, a filter 205, a solenoid valve 206, and a throttling device 207 are sequentially installed on the pipeline between the outlet of the condenser 203 and the evaporator 200. In a specific embodiment, the aforementioned cooling of the heat exchanger is replaced by cooling of the condenser 200.

[0112] The above are merely specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. All technical solutions formed by equivalent transformations or substitutions fall within the scope of protection of the present invention.
