Description

Technical Field

[0001] This invention relates to the field of heat dissipation technology, and more specifically, to a liquid distribution device. Background Technology

[0002] Currently, most water distribution products utilize spray systems. Existing spray methods suffer from several drawbacks: high flow resistance, uneven water distribution, poor wetting ability, and the metal materials used are prone to corrosion, leading to scaling and maintenance difficulties. Furthermore, if high-pressure spraying is used, a large volume of water is blown away instead of evaporated, significantly increasing the unit's WUE (Water Usage Effectiveness) and wasting water resources, resulting in low overall heat dissipation efficiency of evaporative heat exchange.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: the heat dissipation efficiency of evaporative heat exchange is not high. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a liquid distribution device that can effectively solve the problem of low heat dissipation efficiency in evaporative heat exchange.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A liquid distribution device, comprising:

[0007] The capillary liquid storage layer has a heated side on one side along the thickness direction and an exhaust side on the other side.

[0008] The liquid supply channel passes through the capillary liquid storage layer, and the channel wall located between the heated side and the exhaust side has seepage pores to allow liquid to seep into the capillary liquid storage layer.

[0009] When using the aforementioned liquid distribution device, a thermally conductive connection is formed between the heated side of the capillary liquid storage layer and the object receiving heat. This connection can be direct or indirect, allowing heat from the object to be transferred to the capillary liquid storage layer. The liquid working fluid seeping from the pores of the supply channel flows rapidly within the capillary structure, causing the capillary liquid storage layer to accumulate a large amount of liquid working fluid. This forms a gas-liquid interface on the exhaust side. Due to heat absorption, the liquid working fluid evaporates rapidly at the gas-liquid interface, forming a gaseous working fluid, which is then discharged on the exhaust side. At this time, the liquid working fluid inside the capillary liquid storage layer flows towards the exhaust side, and the capillary liquid storage layer is replenished by the liquid working fluid from the supply channel. This results in heat transfer from the heated side to the exhaust side, and the liquid working fluid as a whole also transfers towards the exhaust side in this direction, thus effectively conforming to the field synergy principle and significantly improving heat dissipation efficiency. In summary, this liquid distribution device effectively solves the problem of low heat dissipation efficiency in evaporative heat exchange.

[0010] In some technical solutions, the liquid supply channel extends through the capillary liquid storage layer along the extension direction of the capillary liquid storage layer, and the extension direction of the capillary liquid storage layer is perpendicular to the thickness direction.

[0011] In some technical solutions, the channel wall of the liquid supply channel has the seepage pores evenly distributed in the annular direction.

[0012] In some technical solutions, a support plate is also included, one side of which is covered with the capillary liquid storage layer. The support plate is a heat-conducting plate and can transfer heat from the side away from the capillary liquid storage layer to the capillary liquid storage layer. The side of the capillary liquid storage layer away from the support plate is the exhaust side, and the support plate is a liquid-separating plate.

[0013] In some technical solutions, a hollow fiber membrane in the shape of a tube is included, the internal cavity of the hollow fiber membrane is the liquid supply channel, and the hollow fiber membrane is attached to the corresponding part of the capillary liquid storage layer on all four sides.

[0014] Some technical solutions also include a drive pump, which is used to pressurize both ends of the liquid supply channel.

[0015] In some technical solutions, multiple liquid supply channels are arranged side by side along a first extension direction of the capillary liquid storage layer, and the liquid supply channels extend along a second extension direction of the capillary liquid storage layer. The first extension direction and the second extension direction are perpendicular to each other and are both perpendicular to the thickness direction of the capillary liquid storage layer.

[0016] In some technical solutions, in the second extension direction, a first water collection cavity and a second water collection cavity are respectively provided on both sides of the capillary liquid storage layer, and both ends of each liquid supply channel are respectively connected to the first water collection cavity and the second water collection cavity, and both ends of the drive pump are respectively connected to the first water collection cavity and the second water collection cavity.

[0017] In some technical solutions, the cross-section of the liquid supply channel is circular or elliptical, and the liquid supply channel is located in the middle of the thickness direction of the capillary liquid storage layer; the support plate has a protruding structure on the side away from the capillary liquid storage layer, and the protruding structure has a flow guiding slope.

[0018] In some technical solutions, multiple evaporation components are included. Each evaporation component includes a liquid supply channel, a support plate that is fitted together with each other, and a capillary liquid storage layer. The multiple evaporation components are arranged side by side along the thickness direction of the capillary liquid storage layer, and adjacent evaporation components are arranged opposite to each other, so that a first channel is formed between the oppositely arranged support plates, and a second channel is formed between the oppositely arranged capillary liquid storage layers. Adjacent evaporation components are connected by multiple strip plates arranged in parallel in sequence, and the strip plate located in the first channel and the strip plate located between the second channels are arranged perpendicularly, so that the airflow direction in the first channel and the airflow direction in the second channel are perpendicular to each other. Along the first extension direction, a first total water collection cavity is provided at one end of the first water collection cavity, and a second total water collection cavity is provided at one end of the first water collection cavity in the same direction. The two ends of the drive pump are respectively connected to the first total water collection cavity and the second total water collection cavity.

[0019] In some technical solutions, the capillary liquid storage layer is a superhydrophilic nanofiller layer, which is formed by superhydrophilic TiO2-polymer composite nanomaterials.

[0020] In some technical solutions, the capillary reservoir layer uses at least one of the following particles: alumina particles, beryllium oxide particles, and diamond particles. Attached Figure Description

[0033] This invention discloses a liquid distribution device that can effectively solve the problem of low heat dissipation efficiency in evaporative heat exchange.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-7 , Figure 1 This is a schematic diagram of the liquid distribution device provided in an embodiment of the present invention; Figure 2 This is a partially enlarged structural schematic diagram of the liquid distribution device provided in an embodiment of the present invention; Figure 3This is a schematic diagram of the water supply of the liquid distribution device provided in an embodiment of the present invention; Figure 4 This is a schematic diagram of the internal water flow of the liquid distribution device provided in an embodiment of the present invention; Figure 5 A schematic diagram of the arrangement of multiple evaporation components in the liquid distribution device provided in an embodiment of the present invention; Figure 6 This is a schematic diagram of the back side structure of the support plate provided in an embodiment of the present invention; Figure 7 This is a schematic diagram of the operation of the liquid distribution device provided in an embodiment of the present invention.

[0036] The inventors discovered that, based on the principle of field cooperation, an energy equation analysis was performed on boundary layer flows. By integrating this equation within the thermal boundary layer, it was proven that reducing the angle between the velocity vector and the temperature gradient is an effective measure to enhance convective heat transfer. If spray water is used, the angle between the velocity vector of the spray water and the liquid film temperature gradient is 90°, which is clearly not a method conducive to enhancing heat transfer.

[0037] Based on this, in some embodiments, a liquid distribution device is provided. Specifically, the liquid distribution device includes a capillary liquid storage layer 1 and a liquid supply channel 2. The liquid refers to a liquid working fluid, such as water. When heated, the liquid working fluid evaporates at the interface of the accumulated liquid working fluid, forming a gaseous working fluid that enters the gas space.

[0038] The capillary reservoir 1 has an internal capillary structure, which is generally uniformly distributed in both the extension and thickness directions. When water is used as the liquid working medium, the hydrophilicity of the capillary reservoir 1 allows water to diffuse rapidly within the capillary structure, thus enriching the capillary reservoir 1 with liquid water. It should be noted that, considering the uneven heating of the capillary reservoir 1, the capillary structure may not be uniformly distributed in the extension and / or thickness directions. The formation of the capillary structure can be customized as needed, and can be regular or irregular.

[0039] The capillary liquid storage layer 1 has a heated side 14 to receive external heat, thereby heating the liquid stored inside. External heat is transferred to the capillary structure, primarily through thermal radiation and, more commonly, through thermal conduction. Therefore, the capillary liquid storage layer 1 is preferably also a thermally conductive layer, and can be made of a thermally conductive material. Because external heat can be transferred to the capillary structure, the liquid working fluid within the capillary structure can be heated.

[0040] The capillary liquid storage layer 1 has at least one side forming an exhaust side 13 facing the gas space, which refers to the space mainly containing gas, as opposed to the liquid space. Since the capillary liquid storage layer 1 stores liquid working fluid, a gas-liquid interface is formed on the exhaust side 13. However, if the stored liquid working fluid content is insufficient, the gas-liquid interface may form inside the capillary liquid storage layer 1. When the liquid working fluid inside the capillary liquid storage layer 1 is heated, it evaporates at the gas-liquid interface to form gas, which is then discharged from the exhaust side 13, carrying away the heat. For the capillary liquid storage layer 1, the non-exhaust side 13 (including the heated side 14) can be made compact internally, preventing the passage of water and / or gas. Alternatively, other water-proof structures can be used to achieve a water-proof effect. Similarly, a tightly sealed plate that prevents the passage of gas and liquid can be used as a partition.

[0041] The supply channel 2 penetrates the capillary reservoir 1, allowing for a larger contact area between the two layers. The channel wall of the supply channel 2 has permeation pores 15 to allow permeation into the capillary reservoir 1. Because the supply channel 2 extends along the direction of the capillary reservoir 1, it can permeate a wider area into the reservoir, improving permeation efficiency. The permeation pores 15 prevent the hydraulic pressure inside the supply channel 2 from being transmitted to the capillary reservoir 1, allowing the capillary structure within the reservoir 1 to function better. These permeation pores are generally unidirectional, allowing water in the supply channel 2 to seep out and contact the capillary reservoir 1. Then, under the action of the capillary structure, the water flows into the reservoir 1 and away from the supply channel 2. Liquid can be directly supplied to the interior of the capillary liquid storage layer 1 through the liquid supply channel 2, which extends along or perpendicular to the extension direction of the capillary liquid storage layer 1, to ensure that the liquid working medium can be transported into the interior of the capillary liquid storage layer 1, and preferably towards the heated side 14. Furthermore, supplying liquid through the seepage pores 15 ensures a stable liquid supply, thereby better guaranteeing the formation of a gas-liquid interface on the exhaust side 13.

[0042] In some embodiments, when using the above-described liquid distribution device, the heated side 14 of the capillary liquid storage layer 1 is thermally connected to the heat dissipation object, which can be a direct or indirect connection, allowing the heat from the heat dissipation object to be transferred to the capillary liquid storage layer 1. The liquid working fluid seeping from the seepage pores 15 of the liquid supply channel 2 can flow rapidly in the capillary structure, causing the capillary liquid storage layer 1 to accumulate a large amount of liquid working fluid, thereby forming a gas-liquid interface on the exhaust side 13. Due to heat absorption, the liquid working fluid will evaporate rapidly at the gas-liquid interface, forming a gaseous working fluid, which will be discharged on the exhaust side 13. At this time, the liquid working fluid inside the capillary liquid storage layer 1 will flow to the exhaust side 13, and the capillary liquid storage layer 1 will be replenished by the liquid working fluid from the liquid supply channel. This forms a heat transfer from the heated side 14 to the exhaust side 13, and the liquid working fluid as a whole also transfers to the exhaust side 13 in this direction, thus well conforming to the field cooperation principle, thereby effectively improving the heat dissipation efficiency. In summary, this liquid distribution device can effectively solve the problem of low heat dissipation efficiency in evaporative heat exchange.

[0043] In some embodiments, the liquid supply channel 2 extends through the capillary liquid storage layer 1 along its extension direction, wherein the extension direction of the capillary liquid storage layer 1 is perpendicular to the thickness direction. On the one hand, extending along the capillary liquid storage layer 1 allows the liquid supply channel 2 to simultaneously supply liquid working fluid to more areas of the capillary liquid storage layer 1 along its extension direction; on the other hand, it allows the liquid supply channel 2 to permeate liquid into the capillary liquid storage layer 1 over a wider area, improving permeation efficiency. The extension direction of the capillary liquid storage layer 1 refers to any direction perpendicular to the thickness direction, and the path of the liquid supply channel 2 through the capillary liquid storage layer 1 can be straight or curved.

[0044] In some embodiments, the channel wall of the liquid supply channel 2 is uniformly distributed with permeation pores 15 in the circumferential direction to increase the liquid supply volume through circumferential liquid supply. For some liquid working fluid to flow first to the heated side 14 and then to the exhaust side 13, the heat of the heated side 14 can be carried away as quickly as possible through fluid flow.

[0045] In some embodiments, the channel wall of the liquid supply channel 2 facing the exhaust side 13 may be provided with seepage pores 15, while the channel wall of the liquid supply channel 2 facing the heat receiving side 14 may be closed to prevent liquid supply. This ensures that the flow direction of the liquid working fluid is consistent with the heat transfer direction.

[0046] In some embodiments, the channel wall of the liquid supply channel facing the exhaust side 13 can be closed to prevent liquid supply; while the channel wall of the liquid supply channel 2 facing the heating side 14 is provided with permeation pores 15 to enable liquid supply. This can better ensure that the liquid working fluid has a longer flow path within the capillary reservoir 1.

[0047] In some embodiments, the density of the permeable pores 15 on the channel wall of the liquid supply channel 2 facing the exhaust side 13 can be greater than the density of the permeable pores 15 on the channel wall of the liquid supply channel facing the heating side 14, so that most of the liquid working fluid flows in the direction of heat transfer, while a small amount of liquid working fluid flows towards the heating side 14 first, thus achieving better mutual coordination.

[0048] In some embodiments, the aforementioned capillary liquid storage layer 1 can be directly attached to the condenser coil to directly absorb heat capacity from the condenser coil, thereby improving heat dissipation from the condenser. The condenser here can be a condenser in a mechanical refrigeration system. The capillary liquid storage layer 1 can be completely or partially wrapped around the outer wall of the pipe fitting; the specific configuration can be adjusted as needed.

[0049] In some embodiments, a support plate 3 may also be included, wherein one side of the support plate 3 is covered with the capillary liquid storage layer 1. The support plate 3 provides support for the capillary liquid storage layer 1, and in this case, the support plate 3 may also be a mesh structure or a skeleton structure. In addition, since one side of the support plate 3 is covered with the capillary liquid storage layer 1, the support plate 3 can also serve as a heat-conducting plate, so that heat from the side of the support plate 3 away from the capillary liquid storage layer 1 can be transferred to the capillary liquid storage layer 1 through the support plate 3, thereby achieving a heat conduction effect. If other structures are used, they can also be heat-conducting structures, so as to conduct external heat to the capillary liquid storage layer 1 while supporting it.

[0050] The side of the capillary liquid storage layer 1 away from the support plate 3 is the venting side 13. The support plate 3 is a liquid separator to prevent water in the capillary liquid storage layer 1 from passing through the support plate 3, thereby achieving liquid isolation on both sides of the support plate 3. The support plate 3 can be a square plate or a curved plate, and is not limited thereto.

[0051] In some instances, the support plate 3 can be a graphite / aluminum alloy composite heat-conducting plate with a thickness between 90 and 110 micrometers, such as approximately 100 micrometers. Due to the extremely high ductility of graphite, the high strength of aluminum alloy, and the high thermal conductivity of both, extremely low thermal resistance can be achieved, effectively transferring heat to the superhydrophilic nanofiller layer and realizing high heat flux heat exchange.

[0052] In some embodiments, the capillary liquid storage layer 1 can be attached to a waterproof membrane, which serves to conduct heat while also preventing water penetration. The capillary liquid storage layer 1 does not need to be supported by a mesh structure or other structures.

[0053] In some embodiments, to prevent water from the supply channel 2 from impacting the capillary liquid storage layer 1, a hollow fiber membrane 12 in the shape of a tube can be provided around it, and the internal cavity of the hollow fiber membrane 12 is the aforementioned supply channel 2, while the hollow fiber membrane 12 is attached to the corresponding part of the capillary liquid storage layer 1 on all sides.

[0054] The hollow fiber membrane 12 has a high liquid water flux, and its outer diameter is typically 40~250 μm (micrometers), while its inner diameter is 25~42 μm (micrometers). The wall of the hollow fiber membrane 12 is covered with micropores, the pore size of which allows liquid water to pass through in one direction. The hollow fiber membrane 12 can be an internally pressurized hollow fiber tube. When liquid water passes through the liquid supply channel 2 in the hollow fiber membrane 12, the pressure inside the tube can be slightly higher than the pressure outside, causing liquid water to continuously move from the hollow fiber membrane 12 to the outer superhydrophilic nanofiller.

[0055] In some embodiments, the cross-section of the liquid supply channel 2 can be circular or elliptical. Considering that the hollow fiber membrane 12 itself has a high water permeation flux, but in order to further improve the concentration difference inside and outside the tube and thus the mass transfer effect, the hollow fiber membrane 12 can adopt an elliptical cross-section, or other structures that can increase the concentration difference and enhance the mass transfer within the pervaporation hollow fiber membrane 12. The liquid flow pattern within the elliptical cross-section hollow fiber membrane 12 weakens the concentration boundary layer to avoid concentration polarization, thereby giving it better pervaporation separation performance, and the increase in permeation flux is positively correlated with the ratio of the elliptical half-axis, which can increase it by up to 30%.

[0056] In some embodiments, in order to achieve better pressure inside the hollow fiber membrane 12, a drive pump 4 is preferably included. The drive pump 4 is used to supply liquid to the liquid supply channel 2 to ensure the liquid supply channel 2 has good permeability.

[0057] In some embodiments, the drive pump 4 can be further used to pressurize both ends of the liquid supply channel 2 to increase the internal pressure of the liquid supply channel 2. The drive pump 4 can also be called a micro-pressure pump, which achieves a slightly higher pressure inside the hollow fiber membrane 12 than outside, thus ensuring a continuous and reliable water supply. This water supply system is simple, provides uniform water distribution (achieving 100% coverage of the liquid membrane), is highly operable, and easy to maintain. It avoids the problems of high flow resistance, uneven water distribution, poor wetting ability, and easy corrosion of the metal materials used in spray water distribution, leading to scaling and difficult maintenance.

[0058] In some embodiments, to better supply water to the capillary liquid storage layer 1, it is preferable that the capillary liquid storage layer 1 has multiple liquid supply channels 2 inside. Specifically, the multiple liquid supply channels 2 can be arranged side by side along a first extension direction of the capillary liquid storage layer 1, and the liquid supply channels 2 can be extended along a second extension direction of the capillary liquid storage layer 1, wherein the first extension direction and the second extension direction are perpendicular to each other and both are perpendicular to the thickness direction of the capillary liquid storage layer 1. That is, the extension direction refers to the direction perpendicular to the thickness direction. The liquid supply channels 2 extend along the second extension direction, but it is not required that the extension is in a straight line, as long as the extension trend is in the second extension direction. The capillary liquid storage layer 1 is preferably rectangular, and among two adjacent sides, one side extends in the first extension direction and the other side extends in the second extension direction.

[0059] In some embodiments, in the second extension direction, a first water collection chamber 5 and a second water collection chamber 6 may be respectively provided on both sides of the capillary liquid storage layer 1, and both ends of each liquid supply channel 2 of the capillary liquid storage layer 1 are respectively connected to the first water collection chamber 5 and the second water collection chamber 6, and both ends of the drive pump 4 are respectively connected to the first water collection chamber 5 and the second water collection chamber 6. The number of drive pumps 4 can be reduced.

[0060] In some embodiments, the liquid supply channel 2 can be located in the middle of the capillary liquid storage layer 1 in the thickness direction to ensure more uniform water supply to the surrounding area. Alternatively, the liquid supply channel 2 can be positioned biased towards the support plate 3 so that the liquid supply channel 2 can better supply water to the direction closer to the support plate 3 for more concentrated water replenishment.

[0061] In some embodiments, the support plate 3 may have a protruding structure 7 on the side away from the capillary reservoir 1, and the protruding structure 7 has a flow guiding slope. The protruding structure 7 increases the heat exchange surface, so that the fluid on the side of the support plate 3 away from the capillary reservoir 1 can exchange heat better with the support plate 3.

[0062] Specifically, the protruding structures 7 can be teardrop-shaped, wedge-shaped, or other shapes to facilitate fluid flow and promote heat exchange between fluids. Specifically, the protruding structures 7 can be arranged in an array on the side of the support plate 3 away from the capillary reservoir layer 1.

[0063] In some embodiments, a plurality of evaporation components may be included. Each evaporation component includes a support plate 3 and a capillary liquid storage layer 1 that are fitted together, and a liquid supply channel 2. The plurality of evaporation components are arranged side by side along the thickness direction of the capillary liquid storage layer 1, and adjacent evaporation components are arranged opposite to each other, so that a first channel 8 is formed between the oppositely arranged support plates 3, and a second channel 9 is formed between the oppositely arranged capillary liquid storage layers 1. In practical applications, the fluid to be cooled can flow in the first channel 8, and outdoor air can flow in the second channel 9. The low-temperature outdoor air can carry away the evaporated gas while performing heat exchange. The first channel 8 and the second channel 9 are separated by the support plate 3 to prevent liquid and / or gas communication between them.

[0064] In some embodiments, to better facilitate fluid flow, the fluid flow direction in the first channel 8 and the fluid flow direction in the second channel 9 can be arranged perpendicularly to each other. This facilitates the arrangement of the channels.

[0065] In some embodiments, adjacent evaporation components can be connected by a plurality of sequentially parallel strip plates 16 to achieve internal support. Correspondingly, the strip plates 16 located in the first channel 8 and the strip plates 16 located between the second channels 9 can be arranged perpendicularly, so that the airflow direction in the first channel 8 and the airflow direction in the second channel 9 are perpendicular. The strip plates 16 between the second channels 9 are preferably arranged perpendicularly to the liquid supply channel.

[0066] Correspondingly, in order to better achieve pressure supply, it is preferable that a first total water collection chamber 10 is provided at one end of the first water collection chamber 5 along the first extension direction, and a second total water collection chamber 11 is provided at one end of the first water collection chamber 5 in the same direction; the two ends of the drive pump 4 are respectively connected to the first total water collection chamber 10 and the second total water collection chamber 11.

[0067] In some embodiments, the capillary liquid storage layer 1 can be a superhydrophilic nanofiller layer, which is formed by superhydrophilic TiO2 (lithium dioxide)-polymer composite nanomaterials. The superhydrophilic TiO2-polymer composite nanomaterials are materials with a surface contact angle of less than 10° and extremely high stability in the visible light range. When liquid water flows out of the hollow fiber membrane 12, it rapidly diffuses in the superhydrophilic nanofiller layer, forming a full liquid film coverage, and exchanges heat and mass with the air in the humid channel. In the superhydrophilic nanofiller layer, the motion vector of most of the liquid water tends to be consistent with the temperature gradient vector, satisfying the field cooperation principle, greatly reducing heat loss and improving the utilization of thermal energy.

[0068] In some embodiments, since the thermal conductivity of the superhydrophilic TiO2-polymer composite nanomaterial is low, approximately 0.1~0.3 W / (m∙K) (watts per meter Kelvin), metals such as Al2O3 (alumina, thermal conductivity approximately 20~30 W / (m∙K)) and BeO (beryllium oxide, thermal conductivity approximately 260~300 W / (m∙K)) can be added to this material; alternatively, non-metallic thermally conductive nanoparticles, such as diamond (thermal conductivity approximately 2000~2200 W / (m∙K)), can be added, which greatly increases the thermal conductivity of the filler layer. To ensure the thermal conductivity of the capillary reservoir layer 1, it is preferable that the capillary reservoir layer 1 contains at least one of the following particles: alumina particles, beryllium oxide particles, and diamond particles.

[0069] In some embodiments, after a period of operation, the hydrophilic membrane material becomes contaminated by oil molecules, solid particles, etc., leading to an increase in the contact angle and a significant decrease in hydrophilicity. Therefore, the superhydrophilic nanofiller layer material undergoes surface superhydrophilic modification, such as surface chemical reaction (introducing polar groups like carboxyl, carbonyl, hydroxyl, and sulfonic acid groups through liquid-phase chemical oxidation, which improves the hydrophilicity of the material surface) and surface grafting (blending highly reactive polystyrene maleic anhydride with HFM, utilizing the amidation reaction mechanism between the terminal amine groups of polyetheramine and the anhydride on the membrane surface to achieve in-situ grafting of polyetheramine onto the membrane surface, improving the high hydrophilicity of the surface hydrophilic groups). The filler layer is approximately 300-400 μm thick, and liquid water flows out from the fiber tube and enters this layer. Due to the high thermal conductivity of the packing layer, heat from the dry channel can be quickly transferred to the liquid water. At the same time, its high hydrophilicity allows liquid water to be quickly diffused on the surface of the packing layer and participate in the evaporation and heat absorption process.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
