Description

Technical Field

[0001] The present invention relates to the general field of heat exchange technology, in particular to a counter-current honeycomb channel condenser. Background Art

[0002] A countercurrent condenser is a device that uses convection between hot water and external cold air to achieve heat exchange. Its main purpose is to cool the hot water so that it can be quickly recovered and reused. Its core function is to achieve heat and mass transfer through the countercurrent flow of hot and cold fluids in the channel formed by the filler. The filler is mainly a honeycomb array flow channel composed of multiple groups of parallel plates. The surface of the plate is provided with a capillary structure tube bundle for enhancing heat exchange. During the operation of the equipment, hot water is sprayed from the spray mechanism at the top of the equipment to the filler below. At this time, the hot water forms a thin liquid film that flows downward along the surface of the plate. At the same time, under the action of the fan, the external cold air passes vertically upward from the bottom of the filler through the flow channel formed between the plates, and forms convection heat exchange with the liquid film. At the same time, the heat of the hot water is quickly taken away through the heat conduction of the plate wall and the convection mass transfer at the gas-liquid interface.

[0003] However, since the overall shape of the filler is honeycomb, in which the cross-sectional shape of a single channel is a regular hexagon, due to the geometric symmetry of the hexagonal plate unit, the capillary suction strength in the center area of ​​the flow channel is significantly higher than the capillary force strength in the corner area, which will cause the liquid film to continue to migrate to the center area, thereby forming a thicker liquid film layer. When the thickness of the liquid film at a certain location is high, its gravity will also increase accordingly. At this time, under the action of gravity, the flow rate of the liquid film at that location will accelerate, which leads to a shortened heat exchange time of the liquid film at that location, that is, the time of contact and heat exchange with the cold air is shortened, and the heat transfer is insufficient, thereby affecting the heat exchange effect of the equipment. At the same time, the sharp geometric configuration at the edge of the channel weakens the liquid retention capacity of the microgroove, causing the liquid film to break, thereby forming discrete droplets, which continue to collide under the impact of the rising airflow, thereby aggregating and forming large liquid masses to block the airflow channel, thereby affecting the normal circulation of cold air, thereby greatly increasing the energy consumption of the equipment and increasing production costs.

[0004] To this end, a countercurrent honeycomb channel condenser is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a countercurrent honeycomb channel condenser, which solves the problem that the traditional honeycomb channel edge structure angle is too large, causing the liquid film to break into discrete droplets, and blocking the channel under the action of airflow, thereby increasing the power consumption of the fan. By setting connecting columns and connecting plates, the connecting columns and connecting plates are matched to form a gas-liquid circulation channel by plugging, which is convenient to assemble. The arc surface of the connecting column is in contact with the connecting plate to reduce the angle of the edge, thereby stabilizing the intermolecular force, and then forming a stable and uniform liquid film on the surface of the connecting plate, and generating slight vibrations when air circulates, thereby avoiding droplets blocking the channel, and then avoiding the problem of increased power consumption of the fan caused by channel blockage, thereby achieving energy-saving effect.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A countercurrent honeycomb channel condenser includes a box body, an air inlet net, a water storage tank, a spray system and a fan, and also includes a packing assembly, which is installed inside the box body. The packing assembly includes a connecting column and a connecting plate. The connecting column is a cylinder, and one side of the connecting plate is an arc surface and the other side is a straight surface. Two connecting plates placed in opposite directions are connected between every two connecting columns. Multiple connecting columns and connecting plates are combined and formed into a regular hexagonal shape through snap-fitting. Multiple groups of packing assemblies are combined together to form a honeycomb shape. The angle between the connecting column and the connecting plate is less than ninety degrees; the spray system sprays hot water into the packing assembly and forms a water film flowing from top to bottom on the surface of the connecting plate, and the fan draws cold air from the outside into the bottom of the packing assembly and flows upward.

[0008] Traditional honeycomb fillers are usually one-piece structures, and the shape of a single channel is a regular hexagon with an angle of usually one hundred and twenty degrees. When the angle is greater than ninety degrees, the capillary force will be weakened and it will be difficult for the liquid to form a continuous liquid film. At the same time, since the channel is an integrated structure, it is difficult to clean when there are impurities such as dirt in the channel. Through the above scheme, connecting columns and connecting plates are assembled in a snap-on form to form channels for accommodating liquid and air. When cleaning or replacement due to damage is required, the parts that need to be processed can be disassembled and assembled separately, which is simple and easy to use. In addition, this scheme uses cylindrical connecting columns to replace the corners of traditional channels, so that the angle formed by the column and the edge of the connecting plate is less than ninety degrees, thereby avoiding liquid accumulation at the corners, and making the liquid evenly spread on the surface of the connecting plate and the connecting column, and allowing it to flow smoothly, thereby ensuring its heat exchange effect.

[0009] Preferably, the upper edge of one side of the arc surface of the connecting plate is inclined, and a plurality of vertical convex strips are connected to the arc surface of the connecting plate.

[0010] Through the above solution, the sprayed hot water will fall on the arc surface of the connecting plate and form a uniform water film under the guidance of the convex strips, thereby ensuring that the hot water and cold air can achieve a good heat exchange effect and improving the heat exchange efficiency.

[0011] Preferably, a gap is left between two adjacent connecting plates, and an air duct is formed with the straight surfaces of the two connecting plates as edges, and the lower opening of the air duct is tapered.

[0012] Through the above solution, when hot water covers the surface of the connecting plate, it will also transfer heat to the connecting plate. In order to quickly take away the heat of the connecting plate and achieve better heat dissipation effect, an air duct structure is set. In addition to passing through the channel formed between the arc surfaces of multiple connecting plates, part of the cold air will also flow through the air duct, thereby taking away the heat transferred from the hot water to the connecting plate, thereby achieving better heat exchange effect, thereby improving heat exchange efficiency and reducing fan energy consumption.

[0013] Preferably, a plurality of elastic sheets are provided in the air duct, one end of the elastic sheet is fixedly connected to the straight surface side of the connecting plate, and the other end is a free end.

[0014] Through the above scheme, when cold air passes through the air duct, it will drive the elastic sheet to bend upward. When the elastic sheet is lifted up to a certain extent, the contact angle between the cold air and the elastic sheet changes, resulting in a decrease in the wind force acting on the elastic sheet, causing the elastic sheet to rebound. The elastic sheet rebounds and hits the straight side of the connecting plate, causing it to vibrate slightly, thereby accelerating the flow rate of the water film and further preventing hot water from condensing into droplets and clogging the channel, ensuring space for cold air circulation, avoiding the problem of insufficient cold air and the need to increase the fan power, and thus achieving energy-saving effects.

[0015] Preferably, a sliding groove is provided at the upper end of the connecting column, and a baffle is connected between two adjacent connecting columns through the sliding groove, and the baffle is located on the upper side of the air duct.

[0016] Through the above scheme, in this scheme, the space surrounded by one side of the arc surface of the connecting plate is used as a channel for heat exchange between hot water and cold air. In order to prevent hot water from entering the air duct used for heat dissipation of the connecting plate, a baffle is set at the upper opening of the air duct to prevent hot water from dripping into the air duct.

[0017] Preferably, the width of the baffle is greater than the overall width of the connecting plates on both sides of the air duct, the upper surface of the baffle is an arc surface, and the lower side of the baffle is in a smooth "m" shape.

[0018] Through the above scheme, when hot water is sprayed onto the upper surface of the baffle, it will slide down along its curved surface, and the cold air in the air duct will blow on the lower surface of the baffle when passing through the air duct, and blow out to the outside along the shape of its lower surface, and blow the falling hot water into finer water mist, so that the sprayed hot water is more evenly distributed on the surface of the connecting plate, thereby achieving a better heat exchange effect, enhancing the heat exchange efficiency, and thus achieving an energy-saving effect.

[0019] Preferably, partitions are connected between the plurality of connecting columns, and the partitions are wavy in shape.

[0020] Through the above solution, on the one hand, the partition is used to increase the liquid's adhesion area, thereby increasing the heat exchange area, thereby improving the heat exchange efficiency and reducing the energy consumption required by the fan. On the other hand, the partition plays a role similar to that of a reinforcing rib, thereby enhancing the stability of the overall structure.

[0021] Preferably, a plurality of guide blocks are provided on the surface of the partition, and the guide blocks are in a vertically arranged strip structure.

[0022] Through the above solution, the guide block guides the flow direction of the cold air, assisting it in forming a stable laminar flow, thereby avoiding turbulence and tearing the water film, thereby ensuring the heat exchange effect.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. A countercurrent honeycomb channel condenser of the present invention solves the problem that the edge angle of the traditional honeycomb channel is too large, causing the liquid film to break and affecting the circulation of cold air. By setting connecting columns and connecting plates, the cylindrical connecting columns are used to replace the corners of the traditional channels, so that the angle formed by the cylindrical connecting columns and the edges of the connecting plates is less than ninety degrees, thereby avoiding the problem that the liquid film in the edge area is torn and aggregated into droplets, thereby clogging the channel and affecting the circulation of cold air, and achieving the effect of reducing the energy consumption of the fan and saving energy; at the same time, the connecting plates and connecting columns are installed in a snap-fit ​​form, replacing the traditional integrated structure, which is more convenient and quick when disassembly, cleaning or replacement is required, simple to operate and easy to use.

[0025] 2. A countercurrent honeycomb channel condenser of the present invention, by setting up an air duct and a baffle, uses the cold air flowing in the air duct to quickly take away the heat of the connecting plate, so that the liquid film on the arc surface of the connecting plate loses heat faster, thereby improving the heat exchange efficiency and reducing the energy consumption of the fan. At the same time, when the cold air passes through the air duct, the elastic sheet will cause the connecting plate to vibrate slightly, thereby accelerating the flow rate of the water film and preventing the liquid from condensing into droplets and compressing the cold air circulation space, thereby avoiding the problem of insufficient cold air and the need to increase the fan power, thereby achieving energy saving effect.

[0026] 3. A countercurrent honeycomb channel condenser of the present invention provides partitions. On the one hand, the partitions are connected between multiple connecting columns to act as reinforcing ribs, thereby enhancing the stability of the overall structure. On the other hand, the wavy partitions are used to increase the attachment area of ​​the liquid film, thereby increasing the heat dissipation area, thereby improving the heat exchange efficiency and reducing the energy consumption of the fan. At the same time, the guide blocks on the surface of the partitions are used to assist the circulating cold air to form a stable laminar flow, thereby avoiding the tearing of the water film on the surface of the connecting plate, thereby ensuring the heat exchange effect.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1 to 8The present invention provides a counter-current honeycomb channel condenser, and the technical solution is as follows:

[0038] For details, please refer to Figures 1 to 3 , a countercurrent honeycomb channel condenser includes a box body 1, an air inlet net 2, a water storage tank 3, a spray system 4 and a fan 5. The air inlet net 2 is installed in the area near the lower side of the box body 1, and the fan 5 is installed on the top of the box body 1. When the fan 5 is working, it draws external cold air from the air inlet net 2 into the inside of the box body 1, the water storage tank 3 is arranged at the lower side of the box body 1, and the spray system 4 is arranged inside the box body 1. It also includes a filler assembly 6. The filler assembly 6 is installed inside the box body 1 and is located in the area between the spray system 4 and the air inlet net 2. When working, the spray system 4 sprays hot water on the filler assembly 6. At this time, the hot water forms a water film flowing downward on the surface of the filler assembly 6. At the same time, the cold air extracted by the fan 5 passes through the filler assembly 6 and flows from bottom to top, so that the water film formed by the hot water flows in the opposite direction to the cold air. The hot water after heat exchange falls into the water storage tank 3 for subsequent recycling. The cold air after heat exchange passes through the fan 5 and is discharged to the outside;

[0039] The packing assembly 6 includes a connecting column 601 and a connecting plate 602. The connecting column 601 is a cylinder. One side of the connecting plate 602 is an arc surface and the other side is a straight surface. Two connecting plates 602 placed in opposite directions are connected between every two connecting columns 601. There are multiple mounting grooves on the side of each connecting column 601, and corresponding mounting blocks are provided on the connecting plate 602. When installing, you only need to align the two, and then plug the connecting column 601 into the connecting plate 602 from top to bottom. When cleaning or replacement is required due to damage, the part that needs to be processed can be disassembled and assembled separately, which is simple to operate. It is easy to use. A plurality of connecting columns 601 and connecting plates 602 are combined and snapped together to form a regular hexagonal shape. The connecting columns 601 and connecting plates 602 are snapped together to form a channel for accommodating liquid and air. Multiple groups of filler components 6 are combined together to form a honeycomb shape. At the same time, this solution uses cylindrical connecting columns 601 to replace the corners of traditional channels, so that the angle formed by them and the edges of the connecting plates 602 is less than ninety degrees, thereby avoiding liquid accumulation at the corners, and making the liquid evenly spread on the surfaces of the connecting plates 602 and the connecting columns 601, and making it flow smoothly, thereby ensuring its heat exchange effect.

[0040] As an embodiment of the present invention, refer to Figure 3 and Figure 4The upper edge of the arc surface of the connecting plate 602 is inclined so that water droplets falling on the top of the connecting plate 602 can slide down along its inclined surface and flow downward along the arc surface of the connecting plate 602. A plurality of vertical ridges 603 are connected to the arc surface of the connecting plate 602. The ridges 603 guide the hot water falling on the arc surface of the connecting plate 602 and cooperate with the surface tension of the liquid to form a continuous and stable water film of the hot water, thereby ensuring that the hot water and cold air can achieve a good heat exchange effect and improve the heat exchange efficiency.

[0041] As an embodiment of the present invention, refer to Figure 4 and Figure 5 , since the hot water covers one side of the arc surface of the connecting plate 602, and the connecting plate 602 is usually made of aluminum material, which has the advantage of good thermal conductivity, the hot water will also transfer the heat to the connecting plate 602 when covering the surface of the connecting plate 602. In order to quickly take away the heat of the connecting plate 602 and achieve a better heat dissipation effect, in this solution, a gap is left between the two adjacent connecting plates 602, and an air duct 604 is formed with the straight surfaces of the two connecting plates 602 as edges. In addition to passing through the channels formed between the arc surfaces of the multiple connecting plates 602, part of the cold air will also flow through the air duct 604, thereby taking away the heat transferred from the hot water to the connecting plate 602, thereby achieving a better heat exchange effect, thereby improving the heat exchange efficiency and reducing the energy consumption of the fan 5. The lower side opening of the air duct 604 is tapered, which accelerates the cold air when it enters the air duct 604;

[0042] The air duct 604 is provided with a plurality of elastic sheets 7, one end of the elastic sheet 7 is fixedly connected to the straight side of the connecting plate 602, and the other end is a free end. When the cold air flows rapidly in the air duct 604, the elastic sheet 7 will bend upward first due to the large contact area between the air flow and the elastic sheet 7. When the elastic sheet 7 is lifted up to a certain extent, the contact angle between the cold air and the elastic sheet 7 changes, resulting in a decrease in the wind force acting on the elastic sheet 7. At this time, under the elastic force of the elastic sheet 7, the elastic sheet 7 rebounds downward, and hits the straight side of the connecting plate 602 through the rebound of the elastic sheet 7, causing it to vibrate slightly. At the same time, after the elastic sheet 7 hits the straight side of the connecting plate 602, it itself will vibrate at a certain frequency, thereby repeatedly driving the connecting plate 602 to vibrate. The degree of vibration is not enough to cause tearing of the water film and affect its heat exchange effect, but it can accelerate the speed at which the droplets form a water film to a certain extent, thereby preventing hot water from condensing into droplets and blocking the channel, ensuring space for cold air circulation, and avoiding the problem of insufficient cold air and the need to increase the power of the fan 5, thereby achieving energy saving effect.

[0043] As an embodiment of the present invention, refer to Figure 6 and Figure 7, the upper end of the connecting column 601 is provided with a slide groove 8, and the two adjacent connecting columns 601 are connected with a baffle 9 through the slide groove 8. The two ends of the baffle 9 are provided with corresponding sliders. During the specific installation, it is only necessary to align the slider with the slide groove 8, and then press the baffle 9 down to the specified position. After the installation is completed, the baffle 9 will be located on the upper side of the air duct 604, which can prevent hot water from entering the air duct 604 used for heat dissipation of the connecting plate 602, thereby ensuring that there is sufficient ventilation in the air duct 604, and then the cold air can be fully utilized to carry the heat on the connecting plate 602, thereby accelerating the cooling and heat exchange speed of the water film on one side of the arc surface of the connecting plate 602, avoiding the fan 5 from consuming extra energy, and achieving an energy-saving effect; The width of the baffle 9 is greater than the overall width of the connecting plates 602 on both sides of the air duct 604, so that the spray water sprayed from the spray system 4 will be blocked by the baffle 9 when falling, preventing it from falling into the air duct 604. The upper surface of the baffle 9 is a circular arc surface. When hot water is sprayed onto the upper surface of the baffle 9, it will slide along its arc surface. The lower side of the baffle 9 is a smooth "m" shape. When the cold air in the air duct 604 passes through the air duct 604, it will blow on the lower surface of the baffle 9 and blow outward along the shape of its lower surface, and blow the falling hot water into a finer water mist, so that the sprayed hot water is more evenly distributed on the surface of the connecting plate 602, thereby achieving a better heat exchange effect, enhancing the heat exchange efficiency, and thus achieving an energy-saving effect.

[0044] As an embodiment of the present invention, refer to Figure 8 , a partition 10 is connected between the multiple connecting columns 601, and the partition 10 is slidably connected to the connecting column 601, and its connection method is similar to the connection method between the connecting column 601 and the connecting plate 602. The partition 10 is wavy in shape. On the one hand, the partition 10 is used to increase the adhesion area of ​​the liquid, and the wavy shape of the partition 10 further increases the above effect, thereby greatly increasing the heat exchange area, thereby improving the heat exchange efficiency, and reducing the energy consumption required by the fan 5. At the same time, the partition 10 is connected between the multiple connecting columns 601, and can also play a role similar to a reinforcing rib, thereby enhancing the stability of the overall structure; a plurality of guide blocks 11 are provided on the surface of the partition 10, and the guide block 11 is a vertically arranged strip structure. The guide block 11 guides the flow direction of the cold air to assist it in forming a stable laminar flow, thereby avoiding turbulence tearing the water film and ensuring the heat exchange effect.

[0045] The specific working principle is as follows: first, the fan 5 and the spray system 4 are started. Under the action of the spray system 4, hot water is sprayed down from above the filler assembly 6 and forms a uniform water film on the filler assembly 6. Specifically, most of the spray water will directly fall on one side of the arc surface of the connecting plate 602, and then flow downward under the action of gravity. In this process, the spray water on the connecting plate 602 will form a continuous and uniform water film due to its surface tension and the cooperation with the ridges 603, and the hot water at the contact position between the connecting plate 602 and the connecting column 601 will also reduce the probability of condensing into droplets because the angle at this position is less than ninety degrees, thereby ensuring that the hot water can be spread evenly, thereby ensuring the heat exchange efficiency; in addition, since a plurality of partitions 10 are provided between the connecting columns 601, the spray water will also form a downward-flowing water film on the partition 10, thereby increasing the heat exchange area through the partition 10, and the partition 10 plays a similar role as a reinforcing rib to enhance the stability of the overall structure;

[0046] Under the action of the fan 5, the external cold air enters from the air inlet net 2 and flows from bottom to top through the filler assembly 6, so that it undergoes convection heat exchange with the downward-moving water film. In this process, the partition 10 can not only increase the heat exchange area between the water film and the cold air, but also play a role similar to a guide plate, so that the flowing cold air forms a stable laminar flow, thereby preventing the water film from being torn and affecting the heat exchange. At the same time, since the hot water will also transfer heat to the connecting plate 602 when covering the surface of the connecting plate 602, in order to quickly take away the heat of the connecting plate 602 and achieve a better heat dissipation effect, part of the cold air will enter the air duct 604 between the connecting plates 602, thereby quickly taking away the heat on the connecting plate 602, thereby achieving a better heat exchange effect.

[0047] When the cold air flows through the air duct 604, the elastic sheet 7 will bend upward first due to the large contact area between the air flow and the elastic sheet 7. When the elastic sheet 7 is lifted up to a certain extent, the contact angle between the cold air and the elastic sheet 7 changes, resulting in a decrease in the wind force acting on the elastic sheet 7. At this time, under the elastic force of the elastic sheet 7, the elastic sheet 7 rebounds downward, and the elastic sheet 7 rebounds and hits the straight side of the connecting plate 602, causing it to vibrate slightly. At the same time, after the elastic sheet 7 hits the straight side of the connecting plate 602, it will also vibrate at a certain frequency, thereby repeatedly driving the connecting plate 602 to shake, preventing hot water from condensing into droplets and clogging the channel; when the cold air passes through the air duct 604 and is on the lower surface of the baffle 9, it will be blown outward along the shape of the lower side of the baffle 9, and blow the falling hot water into a finer water mist, so that the sprayed hot water is more evenly distributed on the surface of the connecting plate 602, thereby achieving a better heat exchange effect.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
