Description

DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following describes an integrated evaporative cooling chiller, a chiller operating method, and an electronic device according to embodiments of the present invention with reference to the accompanying drawings.

[0035] like Figure 1 , Figure 2 , Figure 3 The figure shows a schematic structural diagram of the integrated evaporative cooling chiller of the present invention, which includes a frame 1, a fan 2, an evaporator box 4, a heat exchange box 7, a water pump 8 and a cold water reserve tank 11. The frame 1 supports and fixes other components to ensure the stability of the entire unit and facilitate installation and placement.

[0036] like Figure 1 As shown, an air inlet channel 3 is installed between the fan 2 and the evaporation box 4, and a temperature sensor 44, a humidity sensor 45 and a filler 47 are arranged inside the evaporation box 4. After starting, the fan 2 introduces the external airflow into the evaporation box 4 through the air inlet channel 3; a water distributor 41 is arranged above the evaporation box 4, and the water distributor 41 is connected to the water pump 8 to spray water onto the surface of the filler 47 to form a water film. After the external airflow contacts the water film, low-temperature air is formed and transported to the heat exchange box 7 through a pipeline; a heat exchanger 71 is arranged in the heat exchange box 7, and the low-temperature air and the water to be heat exchanged are synchronously transported into the heat exchanger 71 to produce cold water, and the cold water is transported to the cold water reserve tank 11 for storage through a pipeline; a water film thickness adjustment component is arranged in the evaporation box 4, which is used to adjust the thickness of the water film according to the different adaptability of the chiller in a high temperature or high humidity environment.

[0037] After the chiller is started, the fan 2 guides the external air flow into the evaporation box 4 through the air inlet channel 3. At this time, the water pump 8 delivers water to the water distributor 41, and the water distributor 41 sprays water onto the surface of the filler 47 to form a water film. The air contacts the water film, and the water evaporates and absorbs heat, which reduces the air temperature and forms low-temperature air. The temperature sensor 44 and the humidity sensor 45 in the evaporation box 4 monitor the environmental data in real time. According to whether the environment is high temperature or high humidity, the water film thickness is adjusted by the water film thickness adjustment component to meet the evaporative cooling requirements in different environments; then the low-temperature air enters the heat exchanger 71 in the heat exchange box 7 through the pipeline, and at the same time, the water to be heat exchanged is also transported to the heat exchanger 71; in the heat exchanger 71, through heat conduction and heat convection, the low-temperature air transfers the cold to the water to be heat exchanged, so that the water is cooled to produce cold water; the produced cold water is transported to the cold water reserve tank 11 for storage, providing a stable cold source for subsequent use.

[0038] In some embodiments of the present invention, Figure 1 As shown, there are two air inlet channels 3, and the two air inlet channels 3 are respectively connected to different fans 2, and the two air inlet channels 3 are respectively connected to the evaporation box 4 along different inclined directions. The airflows generated by different fans 2 can enter the evaporation box 4 from multiple angles under the guidance of the air inlet channels 3 in different inclined directions. In this way, the airflow can be more evenly distributed in the evaporation box 4 to avoid excessive or weak local airflow. When the airflow evenly impacts the water sprayed by the water distributor 41, it is conducive to the more even spreading of water on the surface of the filler 47, thereby forming a more uniform and stable water film. The uniform water film can improve the heat exchange efficiency between water and air, making the evaporative cooling process more stable and efficient.

[0039] In some embodiments of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, an atomizer 31, an air-water mixer 32 and an air filter 33 are sequentially arranged in the air inlet channel 3 along the direction of entry of the external airflow. The input port of the atomizer 31 is connected to the water source through a pipeline, and the output port of the atomizer 31 is connected to the air-water mixer 32. The atomizer 31 can spray low-temperature water into the air-water mixer 32 in the form of fine droplets, increase the contact area between water and air, and make water evaporate more easily. In a high-humidity environment, these water mists are fully in contact with the high-humidity air entering the air inlet channel 3. Since the temperature of the water mist is relatively low, the water vapor in the air can be partially condensed to reduce the air humidity. Afterwards, the air passes through the air filter 33 to remove the small water droplets carried, and then enters the evaporation box 4. This can reduce the workload of the unit in a high-humidity environment and improve the evaporative cooling efficiency of the unit.

[0040] It should be noted that, for different high-temperature and high-humidity environments where the unit is located, large airflows in different directions can produce different effects respectively; on the one hand, in a high-temperature environment, sufficient and uniform airflow can provide more heat transfer media for the evaporation of water. The large amount of airflow provided by the two air inlet channels 3 and different fans 2 fully contacts the water film on the surface of the filler 47, accelerates the evaporation of water, takes away more heat, and thus produces cold air more efficiently. At the same time, airflows in different directions can form a more complex airflow flow pattern in the evaporation box 4, further increase the contact time and area between the air and the water film, and enhance the cooling effect; on the other hand, in a high-humidity environment, the treatment of humid air is crucial. Air inlet in different directions can introduce humid air into the evaporation box 4 more evenly, and fully contact with the water mist generated by the atomizer 31 and the water in the air-water mixer 32, promote the mixing and condensation of water vapor, and effectively reduce the air humidity. The dehumidified air is then in contact with the water film for evaporative cooling, which can avoid the problem of difficulty in evaporating water due to excessive air humidity, and improve the efficiency and quality of producing cold air in a high-humidity environment. In addition, the strong airflow power provided by the multiple air inlet channels 3 and the fan 2 helps to quickly transport the processed cold air to the heat exchange box 7, thereby ensuring the refrigeration performance of the entire system.

[0041] In some embodiments of the present invention, Figure 4 As shown, at least one flow-equalizing net 43 is arranged between the corresponding water distributor 41 and the filler 47 in the evaporator 4. The flow-equalizing net 43 has an arc-shaped structure when viewed from above. Pads 431 are connected to both sides of the flow-equalizing net 43, and a plurality of leak holes 432 are provided on the surface of the flow-equalizing net 43. The arc-shaped flow-equalizing net 43 can change the flow direction and velocity distribution of the water flow at the outlet of the water distributor 41. After the water flow passes through the water distributor 41, the velocity and direction may be uneven, and the arc-shaped structure can make the water flow transition more smoothly, reduce the impact and turbulence of the water flow, and make the water flow more evenly distributed on the surface of the flow-equalizing net 43. The setting of multiple leak holes 432 can further disperse the water flow into fine water flow beams, so that the water flow can more evenly cover the surface of the filler 47 when it contacts the filler 47 later, which is conducive to forming a uniform water film. In addition, the presence of the leak holes 432 forms more water-air interfaces when the water flow passes through the flow-equalizing net 43. After the water flows out of the leakage hole 432, water droplets or fine water flow lines are formed. These forms increase the contact area between water and air, which is beneficial to water evaporation and heat exchange, and also helps water to spread better on the surface of the filler 47 to form a water film.

[0042] As an example, the leakage holes 432 are designed into different shapes, such as circular, elliptical, square, etc., and the effects of holes of different shapes on water flow distribution and water film formation are analyzed through experiments or simulations to select the optimal hole shape. In addition, a reasonable design of the arrangement of the leakage holes 432, such as staggered arrangement rather than linear arrangement, can make the water flow more evenly dispersed, avoid water flow concentration or blank areas, and further improve the uniformity of the water film.

[0043] As another example, multiple layers of flow-balancing nets 43 are arranged at intervals, and the positions and sizes of the leak holes 432 of each layer of flow-balancing nets 43 can be different. After the water flows through the multiple layers of flow-balancing nets 43, it will be gradually dispersed and adjusted, further improving the uniformity and stability of the water flow. At the same time, the multi-layer structure can also increase the number of contacts between water and air, which is beneficial to water evaporation and heat exchange.

[0044] In some embodiments of the present invention, Figure 1 , Figure 5 As shown, the evaporation box 4 is connected to a bypass valve 42, and the bypass valve 42 is connected to the heat exchanger 71 through a pipeline. When the temperature and humidity of the external air are suitable and do not need to go through a complete evaporative cooling process, the bypass valve 42 can be opened to allow part of the airflow to directly enter the heat exchanger 71. This can reduce the workload of the evaporation box 4, reduce energy consumption, improve the operating efficiency of the unit, and achieve flexible operation control. The bypass valve 42 can automatically adjust the water flow path according to parameters such as water temperature and flow rate to optimize the system operation efficiency.

[0045] In some embodiments of the present invention, Figure 5 As shown, the inner wall of the evaporation box 4 is installed with a nozzle 46, and the nozzle 46 is connected to the water source through a pipe. As the evaporative cooling process proceeds, the water in the water film evaporates continuously, causing the thickness of the water film to gradually become thinner. The side wall nozzle 46 can spray water mist onto the surface of the filler 47 in a timely manner to replenish the water lost by evaporation of the water film, so that the water film is maintained at a suitable thickness, ensuring the stability and continuity of the water film, and continuously and efficiently performing evaporative cooling. In addition, the water sprayed by the water distributor 41 may be unevenly distributed on the surface of the filler 47 under the influence of gravity and airflow. The side wall nozzle 46 sprays water mist onto the surface of the filler 47 from different angles, which can fill the area with uneven water distribution, allowing the water to cover the surface of the filler 47 more evenly, promoting the formation of a more uniform water film, and improving the heat exchange efficiency between the water film and the air.

[0046] As an example, the structure of the nozzle 46 is optimized. A variable aperture nozzle 46 is selected, and the aperture of the nozzle 46 is changed by electromagnetic or hydraulic drive, and the spray volume and droplet size are adjusted according to the operating state of the unit (such as ambient temperature and humidity, and the water film condition in the evaporation box 4). For example, the aperture is increased at high temperature and the spray volume is increased; the aperture is reduced at high humidity to make the droplets finer and enhance the dehumidification effect. At the same time, a multi-directional nozzle 46 is used, which can adjust the spray angle in multiple directions to compensate for the uneven airflow and water distribution in the evaporation box 4, and ensure that the water mist evenly covers the surface of the filler 47.

[0047] In some embodiments of the present invention, Figure 6 As shown, at least three fillers 47 are provided, and the multiple fillers 47 are divided into upper and lower layers, and the fillers 47 between the upper and lower layers are staggered. In this embodiment, there are five fillers 47 in total. The five fillers 47 are placed at intervals. The advantage of this method is that the air circulation is better. The air can flow freely in the gaps between the fillers 47, which reduces the resistance of air flow and enables the air to be more evenly distributed in the area of ​​the fillers 47, thereby improving the heat exchange efficiency. At the same time, the interval placement is conducive to the maintenance and replacement of a single filler 47. If a problem occurs in a piece of filler 47, it will not affect the normal operation of other fillers 47. And for the formation of water film, the water flow can be redistributed in the gaps between the fillers 47, which is conducive to the renewal and uniformity adjustment of the water film.

[0048] It should be noted that multiple fillers 47 are installed in layers, with a certain distance between each layer of fillers 47, and the upper and lower layers of fillers 47 are staggered. This installation method can redistribute the water flow on the lower layer of fillers 47 after passing through the upper layer of fillers 47, increase the renewal opportunity of the water film, and avoid the water film being too thick or too thin at the same position. At the same time, the staggered structure can also guide the air to form a more complex flow path in the evaporator 4, improve the contact efficiency between the air and the water film, and enhance the heat exchange effect.

[0049] As an example, when the honeycomb filler 47 with a cross section is installed in layers and staggered, the air will constantly change direction when passing through the honeycomb pores of different layers, and the contact with the water film will be more complete.

[0050] As an example, the filler 47 is installed in the evaporator 4 at a certain tilt angle, and the tilt angle is usually between 15° and 45°. Such a tilt setting can make it easier for water to flow smoothly along the surface of the filler 47 under the action of gravity, avoiding local water accumulation or water flow stagnation, thereby helping to form a uniform and continuous water film. For example, for a corrugated filler 47, the tilted installation can accelerate the water flow down along the direction of the corrugation, while increasing the contact time and contact area between water and air, and strengthening the heat exchange process.

[0051] In some embodiments of the present invention, Figure 5 , Figure 7 As shown, both sides of the top of the packing 47 are provided with a water film thickness adjustment component, which includes a baffle 48 and a rotating shaft 49; the baffle 48 is fixedly connected to the rotating shaft 49, one end of the rotating shaft 49 is rotatably connected to the inner wall of the evaporation box 4, and the other end of the rotating shaft 49 penetrates the evaporation box 4 and is coaxially connected to a gear 491. A cylinder 492 and a rack 493 are provided between the gears 491 on the left and right sides of the evaporation box 4 corresponding to the surface of the evaporation box 4, and the rack 493 is slidably connected to the surface of the evaporation box 4. The left and right sides of the rack 493 are formed with teeth that mesh with the gear 491, and the output end of the cylinder 492 is connected to one end of the rack 493. The rack 493 is pushed to move by the cylinder 492, driving the gear 491 to rotate, thereby realizing the angle adjustment of the baffle 48, changing the gap between the baffle 48 and the top surface of the packing 47, and then achieving the purpose of adjusting the water film thickness.

[0052] Through the above-mentioned water film thickness adjustment component, the thickness of the water film can be flexibly adjusted. Under hot and dry climate conditions, the relative humidity of the air is low and the potential for water evaporation is large. At this time, a thicker water film can allow more water to adhere to the surface of the filler 47. A thicker water film has a larger evaporation area. In a high temperature environment, sufficient water can make full use of the latent heat of evaporation, accelerate the evaporation process of water, and take away more heat, thereby quickly reducing the air temperature and enhancing the cooling effect. In an environment with high air humidity, it is relatively difficult for water to evaporate. A thinner water film can avoid excessive water vapor partial pressure on the surface of the water film, which is conducive to water evaporation, prevents the cooling efficiency from being reduced due to poor water evaporation, and creates good conditions for subsequent evaporative cooling.

[0053] In addition, a thicker water film can dilute the concentration of impurities in the water to a certain extent and reduce the deposition of impurities on the surface of the filler 47. When the water quality is poor, a thick water film can provide better buffering, reduce the impact of impurities on the heat exchange surface, and extend the cleaning cycle and service life of the equipment. In addition, in some cases, a thick water film can better absorb heat from the air and prevent local overheating caused by a thin water film.

[0054] In some embodiments of the present invention, Figure 7 , Figure 8 As shown, a rib 471 is formed on the surface of the filler 47 , and an avoidance gap 481 is formed on the side of the baffle 48 close to the filler 47 . The opening size of the avoidance gap 481 matches the cross-sectional size of the rib 471 .

[0055] It should be noted that the filler 47 plays a key role in the evaporative cooling chiller, and its structural composition is diverse. Different structures have a significant effect on the effect of forming a water film. The current common materials are plastic fillers, metal fillers and ceramic fillers. Among them, common plastic fillers include polypropylene (PP), polyvinyl chloride (PVC), etc. Among the geometric structures of the filler 47, corrugation is the most common form, which is divided into oblique corrugations, vertical corrugations, etc. The presence of corrugations increases the specific surface area of ​​the filler 47, so that the water flow forms a tortuous flow path on the surface of the filler 47, prolonging the contact time between water and air, which is beneficial to heat exchange. At the same time, the corrugated shape helps the water to be evenly distributed on the surface of the filler 47 to form a stable water film. Other structures include honeycomb, filament, spherical or granular.

[0056] As an example, the protruding ribs 471 increase the roughness of the surface of the filler 47, increase the friction between the water and the filler 47, and thus improve the adhesion of the water film on the surface of the filler 47. This helps prevent the water film from sliding off too quickly under the action of gravity, airflow, etc., so that the water film can be more stably attached to the filler 47, ensuring the continuation of the evaporative cooling process. In addition, the ribs 471 can guide the direction of the water flow, so that the water is more evenly distributed on the surface of the filler 47. When water is sprayed from the water distributor 41 onto the filler 47, the ribs 471 can disperse the water flow into multiple small water flow paths to avoid the water flow being concentrated in certain areas, so that the water film can cover the surface of the filler 47 more comprehensively and evenly, and improve the heat exchange area and efficiency between the water film and the air.

[0057] As an example, Figure 8 As shown, the top surface of the baffle 48 is set as an inclined guide surface 482, which has a certain angle with the horizontal direction. Under the action of gravity, water can flow smoothly along the inclined direction and form a uniform water film during the flow. The angle is generally more suitable at 15°-45°.

[0058] As an example, a corrugated structure is provided on the surface of the baffle 48, which can increase the contact area between the water and the baffle 48, so that the water forms more eddies and turbulences during the flow, slows down the flow rate of the water, and allows the water to be more evenly distributed on the surface of the baffle 48, which helps to form a water film with uniform thickness.

[0059] In some embodiments of the present invention, Figure 1 As shown, the evaporation tank 4 is connected to a water purifier 5 and a wastewater collection tank 6 in sequence through pipelines. The water purifier 5 purifies the water after contact with the air, removes impurities, microorganisms and dissolved substances in the water, and prevents the deterioration of water quality from causing corrosion and scaling of the equipment. The purified water enters the wastewater collection tank 6 and can be recycled and reused, realizing the recycling of water resources, which meets the requirements of energy conservation and environmental protection.

[0060] As an example, a temperature sensor 44 and a liquid level sensor are provided in the wastewater collection tank 6, and the wastewater treatment method is automatically controlled according to the temperature and liquid level of the wastewater. For example, when the wastewater temperature is low and the liquid level is high, it is preferred to enter the cold water storage tank 11 after natural cooling; when the wastewater temperature is high or the liquid level is low, the wastewater can be sent to the heat exchanger 71 for cooling. The cooled water can also be directly input into the water distributor 41 for use, or in a high humidity environment, the cooled water can be input into the atomizer 31 for use.

[0061] It should be noted that even if the temperature of the water sprayed onto the surface of the filler 47 is not much different from that of the environment, cold air can still be produced. This is mainly based on the principle of heat absorption by evaporation of water. However, the sustained effect in high temperature and high humidity environments is different:

[0062] In a high temperature environment, the relative humidity of the air is usually low (not absolute, there are also high temperature and high humidity conditions, but here we will first discuss the general high temperature and low humidity conditions), and the air has a stronger ability to accommodate water vapor at this time. Although the spray water is not much different from the ambient temperature, due to this characteristic of the air, water has a greater evaporation potential. As long as the unit is well ventilated, can continuously provide enough air to contact the water film, and has a stable water supply to maintain the formation of the water film, water can continue to evaporate, continuously absorb heat, and continue to produce cold air. Therefore, in a high temperature environment, this method of producing cold air by relying on water evaporation refrigeration can be carried out continuously and is relatively efficient, because high temperature and low humidity conditions are conducive to the evaporation of water;

[0063] In a high humidity environment, the relative humidity of the air is high, which means that the water vapor content in the air is close to saturation, and the evaporation of water becomes more difficult. Although water can still evaporate, the evaporation rate will be significantly slower. When the spray water temperature is not much different from the ambient temperature, the heat absorbed by water evaporation is limited, and the cooling effect will be affected to a certain extent. However, through some special designs and measures, such as optimizing the filler 47 structure in the embodiment of the present invention to increase the contact area and time between water and air, increasing the air flow rate to update the contact surface between air and water film, pre-treating the air to reduce humidity, etc., it is possible to maintain water evaporation to a certain extent and continuously produce cold air.

[0064] This chiller can adaptively adjust the water film thickness according to different high temperature or high humidity environments through the water film thickness adjustment component; at high temperatures, the appropriate water film thickness helps to enhance the evaporative cooling effect and reduce the air temperature; at high humidity, adjusting the water film thickness can optimize the heat and moisture exchange process between the air and the water film, thereby improving the overall performance of the unit under different environmental conditions.

[0065] Corresponding to the integrated evaporative cooling chiller of the above embodiment, the present invention further provides an integrated evaporative cooling chiller operation method, comprising the following steps:

[0066] Start the water pump 8 and the fan 2 in sequence to establish water circulation and air circulation. According to the initial ambient temperature and humidity, the fan 2 speed, the water pump 8 flow rate and other parameters can be set manually or with the help of an intelligent control system;

[0067] When in a high temperature environment, the water film thickness adjustment component is used to increase the water film thickness, and the rack 493 is driven by the cylinder 492 to drive the gear 491, so that the baffle 48 adjusts the angle, so that more water adheres to the surface of the filler 47, and the latent heat of evaporation of water is used to enhance the cooling effect. In this way, the principle of evaporative refrigeration can be fully utilized to quickly reduce the air temperature in a high temperature environment. At the same time, the speed of the fan 2 is appropriately increased to increase the air intake. Adequate airflow can provide more heat transfer carriers for the evaporation of water, accelerate the evaporation process of water, and take away more heat, thereby effectively improving the refrigeration efficiency. Finally, the wastewater reaches the wastewater collection box 6 through the water purifier 5, and after natural cooling or rapid introduction into the heat exchanger 71 for cooling, it waits for subsequent use. In this way, efficient use of water resources is achieved, and the waste heat of the wastewater is further enhanced.

[0068] In a high humidity environment, the thickness of the water film is reduced to avoid difficulties in water evaporation due to excessive air humidity. The water film thickness adjustment component is used to reduce the retention of water on the surface of the filler 47 by the baffle 48 to prevent the water film from being too thick and affecting the evaporation efficiency. At the same time, the atomizer 31, the air-water mixer 32 and the air filter 33 of the air inlet channel 3 are turned on to strengthen the air dehumidification process, so that the humid air is fully in contact with the atomized water, promote the condensation of water vapor, reduce the air humidity, and create more favorable conditions for subsequent evaporative cooling. The wastewater can be naturally cooled in the wastewater collection box 6 first, and then sprayed into the air inlet channel 3 through the atomizer 31, and the low-temperature wastewater is used to further reduce the air humidity. This method not only realizes the recycling of wastewater, but also effectively improves the air conditions in a high humidity environment. In this process, the temperature sensor 44 and the humidity sensor 45 are used to monitor the environmental parameters in the evaporation box 4 in real time, and the key parameters such as the speed of the fan 2, the flow rate of the water pump 8, and the thickness of the water film are dynamically adjusted according to the cold water demand and environmental changes to ensure that the unit is always in an efficient and stable operating state.

[0069] The operation method of the chiller in the present invention designs different operation strategies for high temperature and high humidity environments. At high temperatures, the thickness of the water film is increased, the speed of the fan 2 is increased, and the waste water is recycled, so as to make full use of the principle of evaporative refrigeration, quickly reduce the air temperature, and improve the refrigeration efficiency; at high humidity, the thickness of the water film is reduced, air dehumidification is strengthened, and waste water is used to reduce humidity, so as to solve the problem of evaporation difficulties caused by excessive air humidity and ensure the stable operation of the unit in a complex environment. At the same time, this method realizes the efficient use of water resources by introducing waste water into the heat exchanger 71 for cooling and then recycling it, and at the same time uses the waste heat of waste water to enhance the cooling effect and reduce energy consumption, which conforms to the concept of energy conservation and environmental protection and can effectively reduce operating costs.
