Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and in particular to an improved air-to-water refrigeration device. Background Art

[0002] An air water generator is a device that can extract moisture from the air and convert it into drinking water. It mainly introduces outside air through a fan, performs preliminary filtration through an air filter, and then inputs it into a compressor for pressurization and temperature increase. The high-temperature and high-pressure air is then input into the condenser of the refrigerant cycle, so that the moisture in the air contacts the low-temperature condenser and condenses into liquid water on the surface of the condenser. As the amount of liquid water on the surface of the condenser gradually increases, the nearby liquid water will merge with each other to form droplets, which will eventually drip into the water storage tank below. After filtering the water through a membrane assembly or other filtering device, it is input into a water circulation sterilization and purification system for further safe processing to obtain drinkable liquid water.

[0003] In the above process, due to the small size of the domestic air water making machine, a large condenser cannot be installed, so that the surface area of ​​the condenser that the high-temperature and high-pressure air can contact per unit time is small, and the high-temperature and high-pressure air will also pass through the condenser quickly, resulting in a short heat exchange time and inability to obtain effective liquid water condensation. In the large-volume industrial air water making machine, the condenser is large in size, and in order to increase the heat exchange area, the pipes in the condenser are arranged in a complex manner, which will cause the liquid water condensed on the surface of the condenser to exist for a long time. The condensed water above will drip onto the condenser pipe below when it falls. In this reciprocating process, the time for the liquid water to leave the condenser will be prolonged, forming a water film, which will hinder the transfer of heat and cause the overall heat exchange of the condenser to be reduced. Summary of the invention

[0004] The present application proposes an improved air-to-water refrigeration device, which has the advantages of inputting high-temperature and high-pressure air into a single cooling space for long-term heat exchange, and the up-and-down movement of the water accumulation seat changes the volume of the cooling space and changes the flow state of the air, forming a temperature difference space with high temperature at the top and low temperature at the bottom in the cooling space, and the temperature difference space allows the air to form natural convection, and the self-circulating air increases the turbulent state and improves the heat exchange effect, the water accumulation seat is lifted up and hits the partition condensation plate to vibrate the condenser tube and the partition condensation plate, and the vibrating condenser tube and the partition condensation plate cause the internal coolant to fluctuate to improve the heat exchange effect, and the vibrating condenser tube and the partition condensation plate allow the condensed liquid to quickly separate, so as to solve the problems in the existing air-to-water maker that the condenser is small in size resulting in poor heat exchange effect and the complex arrangement of the condenser pipes resulting in slow liquid separation.

[0006] Preferably, an annular limiting ring is provided at the top of the inner wall of the outer sleeve, and a buckling groove is provided at the top of the inner wall of the partition condensation plate near the outer sleeve, and the limiting ring is sleeved in the buckling groove to limit the height position of the partition condensation plate.

[0007] Preferably, elastic sealing strips are provided on the outer side of the partition condensation plate away from the central axis and on the groove wall of the snap-fit ​​groove. The partition condensation plate is respectively fitted with the inner wall of the outer sleeve, the limiting ring and the bottom end of the top cover through the elastic sealing strips to avoid leakage of liquid and gas and provide a certain movement space for the partition condensation plate in the axial direction.

[0008] Preferably, the position of the air inlet pipe in the height direction is higher than the drain pipe to prevent liquid from entering the air inlet pipe. In the circumferential direction, the exhaust port, drain pipe and air inlet pipe are staggered in sequence. In the circumferential direction, the angle between the exhaust port and the drain pipe is not greater than forty degrees, the angle between the drain pipe and the air inlet pipe is not greater than forty degrees, and the angle between adjacent partition condensation plates is smaller than the angle between the drain pipe and the air inlet pipe to prevent adjacent cooling spaces from being connected to the air inlet pipe, drain pipe or exhaust port at the same time.

[0009] Preferably, the top side wall of the water collection seat is fitted with the bottom of the inner wall of the outer sleeve, and a sealing ring is provided to prevent liquid leakage. The top of the water collection seat is parallel to the lowest point of the drain pipe, which is used to smoothly drain the liquid on the water collection seat.

[0010] Preferably, a fixing ring is provided at the top of the power shaft, and a support plate is provided on the fixing ring for limiting the position of the support plate and providing rotational power, and uniformly distributed pressure springs are provided between the top end of the support plate and the bottom end of the water collection seat for controlling the height position of the water collection seat.

[0011] Preferably, a variable ring is fixedly sleeved on the outer bottom of the outer sleeve, and extension blocks evenly distributed around the circumference are fixedly connected to the outer side of the bottom end of the water accumulation seat. The top of one side of the extension block protrudes out of the water accumulation seat and fits with the bottom end of the variable ring. At this time, the pressure spring is compressed to limit the height position of the water accumulation seat and provide upward power.

[0012] Preferably, the bottom end of the outer sleeve is higher than the bottom end of the variable ring, and the bottom end of the variable ring is provided with lifting grooves evenly distributed around the circumference, for providing space for a pressure spring to push the water accumulation seat and the extension block to lift up; a sliding arc surface II is provided on one side in the circumferential direction of the lifting groove, and a sliding arc surface I is provided on one side of the extension block protruding out of the water accumulation seat; the sliding arc surface I and sliding arc surface II are arranged opposite to each other, and the sliding arc surface II is used to squeeze the sliding arc surface I to drive the water accumulation seat to move downward.

[0013] Preferably, there is a distance between the bottom end of the partition condensation plate and the bottom of the movable groove, which is used to provide space for the water accumulation seat to move upward and hit the partition condensation plate.

[0014] The present application provides an improved air-to-water refrigeration device, which forms a plurality of separate cooling spaces by separating the condensing plate and the outer sleeve, and continuously rotates the separated condensing device at the same time, so that the high-temperature and high-pressure gas can enter the connected cooling space from the bottom through the air inlet pipe, and flow upward to contact the staggered condensing tubes for heat exchange. Since the position of the cooling space is constantly changing, the content of high-temperature and high-pressure air to be cooled in a single cooling space is limited, and the cooling liquid in the condensing tube continuously flows and circulates, so that the high-temperature and high-pressure air in the single cooling space can obtain long-term and efficient heat exchange, and condenses into liquid on the condensing tube and then drips downward onto the water storage seat. When the cooling space here is connected to the drain pipe, the water on the water storage seat in the cooling space here is discharged.

[0015] At the same time, during the continuous rotation of the separating condensing device, the water accumulation seat and the extension block at the bottom of the water accumulation seat will be driven to rotate synchronously. When the extension block rotates to the lifting groove, the extension block will temporarily lose the upward restriction of the variable ring. At this time, the pressure spring will quickly push the water accumulation seat up, and then the water accumulation seat continues to drive the extension block to rotate. After the sliding arc surface Ⅰ on the extension block contacts the sliding arc surface Ⅱ in the lifting groove, it will be forced to move downward, driving the water accumulation seat to slowly move downward and reset, and compress the pressure spring, so that the water accumulation seat makes intermittent up and down reciprocating motion during the rotation process. When the water accumulation seat moves upward quickly, the volume of the cooling space will be reduced, and the air in the cooling space will be pushed to move upward faster. When the water accumulation seat moves slowly downward, the volume of the cooling space will be increased, and the air in the cooling space will be attracted to move downward, so that the air in the cooling space flows back and forth between the condenser tubes, prolonging the contact time between the air and the condenser tubes, improving the turbulent state of the airflow, and further improving the heat exchange effect. When the cooling space is connected to the exhaust port, the above-mentioned air movement state will accelerate the discharge of gas in the cooling space.

[0016] At the same time, when the water accumulation seat is in the process of rapid lifting, the bottom of the movable groove will hit the bottom end of the partition condensation plate, so that the partition condensation plate drives the condensation tube to perform impact vibration. The short-term impact vibration will cause the circulating cooling liquid in the partition condensation plate and the condensation tube to fluctuate, thereby increasing the turbulent state of the coolant, thereby increasing the heat exchange capacity of the condensation tube per unit time, and the vibration of the partition condensation plate and the condensation tube will cause the liquid condensed on the partition condensation plate and the condensation tube to quickly slide down, gather and drip, thereby accelerating the drainage of the liquid on the partition condensation plate and the condensation tube.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Embodiment 1 See also Figures 1 to 3 An improved air-to-water refrigeration device comprises an outer sleeve 1, an air inlet pipe 2 and a drain pipe 3 are welded to the bottom of the outer sleeve 1, high-temperature and high-pressure air is input into the outer sleeve 1 through the air inlet pipe 2, and liquid water is condensed on the partition condensation plate 8 and the condensation tube 9 after heat exchange with the partition condensation plate 8 and the condensation tube 9. The liquid water falls under the action of gravity and gathers on the water accumulation seat 12. When the cooling space is connected to the drain pipe 3, the gathered liquid water will be discharged through the drain pipe 3. The top of the inner wall of the outer sleeve 1 is fixedly connected with an annular limit ring 4 by bolts, the inner side of the outer sleeve 1 is movably sleeved with a partition condensation device, and the top of the outer sleeve 1 is fixedly connected with a top cover 5 by bolts.

[0022] See also Figure 2 , Figure 4 The partition condensation device includes a central axis 74 in the center, partition condensation plates 8 fixedly connected to the outer circumference of the central axis 74 and evenly distributed, and condensation tubes 9 staggeredly fixed on the partition condensation plates 8. The top end of the central axis 74 movably passes through the center of the top cover 5. In the axial direction, the condensation tubes 9 are staggered, so that the partition condensation device can be continuously rotated in the outer sleeve 1. The high-temperature and high-pressure air entering the cooling space will move upward and contact the partition condensation plates 8 and the staggered condensation tubes 9. When the air moves upward, the staggered condensation tubes 9 will change the movement path of the air, improve the turbulent state of the air, and improve the heat exchange efficiency.

[0023] See also Figure 2 , Figures 4 to 5A hollow cavity is provided in the partition condensation plate 8 and connected with the condensation tube 9. A coolant input flow channel 10 and a coolant discharge flow channel 11 are provided in the central axis 74. The top openings of the coolant input flow channel 10 and the coolant discharge flow channel 11 are connected with the existing circulating cooling system. The bottom opening of the coolant input flow channel 10 is connected with the bottom of one of the partition condensation plates 8. The bottom opening of the coolant discharge flow channel 11 is connected with the top of one of the partition condensation plates 8, so that the coolant can first enter the bottom of the partition condensation plate 8 and then move upward, and then leave from the top of the partition condensation plate 8, so that the temperature of the condensation tube 9 and the partition condensation plate 8 gradually increases from bottom to top (the coolant at the bottom first contacts the high-temperature and high-pressure air for heat exchange and then flows upward, continuously absorbing the heat of the high-temperature and high-pressure air, so that the temperature above is greater than the temperature below). In the cooling space Start to connect the air intake pipe 2, and high-temperature and high-pressure air is input from the bottom. Due to the high initial pressure, it will first diffuse to the surroundings, and then the cooling space leaves the air intake pipe 2. As time goes by, after the high-temperature and high-pressure air condenses into liquid water, the air temperature decreases and the pressure decreases. At this time, due to the high temperature above, the input cooled and reduced-pressure air will be heated by the heated coolant above and expand. The density of the expanded air decreases and it begins to rise, forming an updraft. At the same time, the temperature below the cooling space is low, which makes the air temperature below low. Due to its high density, the cold air will begin to flow to the bottom to fill the space left by the updraft, forming a downdraft. This up and down airflow will form a natural convection cycle in the cooling space, thereby increasing the contact time and contact area between the air and the condenser tube 9, thereby improving the heat exchange efficiency.

[0024] See also Figures 2 to 5 A buckling groove 81 is provided at the top of the inner wall of the outer sleeve 1 near the partition condensation plate 8, and the limiting ring 4 is movably sleeved in the buckling groove 81, so that the limiting ring 4 provides position support for the partition condensation plate 8 to maintain the height of the partition condensation plate 8, and an elastic sealing strip 82 is fixedly connected to the outer side of the partition condensation plate 8 away from the central axis 74 and the groove wall of the buckling groove 81. The partition condensation plate 8 is respectively fitted with the inner wall of the outer sleeve 1, the limiting ring 4 and the bottom end of the top cover 5 through the elastic sealing strip 82, and a cooling space is formed between adjacent partition condensation plates 8. The cooling space is sealed by the elastic sealing strip 82 to reduce the leakage of gas and liquid in a single cooling space. At the same time, the limited elasticity of the elastic sealing strip 82 provides a certain space for the subsequent movement of the partition condensation plate 8.

[0025] See also Figures 1 to 3A cooling space is formed between adjacent partition condensation plates 8. An exhaust port 6 is provided on the top cover 5. The gas after heat exchange in the cooling space is discharged through the exhaust port 6. The position of the intake pipe 2 in the height direction is higher than the drain pipe 3 to prevent liquid water on the water accumulation seat 12 from entering the intake pipe 2. In the circumferential direction, the exhaust port 6, the drain pipe 3 and the intake pipe 2 are staggered in sequence. In the circumferential direction, the angle between the exhaust port 6 and the drain pipe 3 is not greater than 40 degrees, the angle between the drain pipe 3 and the intake pipe 2 is not greater than 40 degrees, and the angle between adjacent partition condensation plates 8 is smaller than the angle between the drain pipe 3 and the intake pipe 2, so that a single cooling space When the air intake pipe 2 is connected during the rotation, this cooling space will no longer be connected to the drain pipe 3 and the exhaust port 6. At this time, only high-temperature and high-pressure gas enters the cooling space connected to the air intake pipe 2. At the same time, another nearby cooling space is connected to the drain pipe 3 to take away the liquid water in this cooling space. At this time, the cooling space connected to the drain pipe 3 is connected to the adjacent cooling space on one side of the air intake pipe 2 and is connected to the exhaust port 6 to discharge the air after heat exchange in the cooling space. In summary, the cycle steps are as follows: after the air intake pipe 2 inputs high-temperature and high-pressure gas for heat exchange, the air after heat exchange is discharged first when passing through the exhaust port 6, and then the drain pipe 3 is connected to discharge the liquid water.

[0026] See also Figures 2 to 3 , Figure 6 A water accumulation seat 12 is arranged below the partition condensation device, and a movable groove 13 is opened at the top of the water accumulation seat 12. The bottom of the partition condensation plate 8 is inserted into the movable groove 13, so that when the partition condensation plate 8 rotates following the central axis 74, it can squeeze the groove wall of the movable groove 13, driving the water accumulation seat 12 to rotate synchronously, and the top side wall of the water accumulation seat 12 is in contact with the bottom of the inner wall of the outer sleeve 1, and a sealing ring is provided to prevent leakage of liquid water on the water accumulation seat 12. The top of the water accumulation seat 12 is parallel to the lowest point of the drain pipe 3, so that the liquid water accumulated on the water accumulation seat 12 can be discharged through the drain pipe 3.

[0027] See also Figure 1 to Figure 2 , Figures 4 to 5 A power shaft 7 is provided at the bottom end of the central shaft 74, and the top of the power shaft 7 is fixedly connected with evenly distributed plug rods 71. The plug rods 71 ​​are movably inserted into the bottom end of the central shaft 74. The power shaft 7 is powered by an existing power device, such as a transmission and a drive motor. The specific speed of the power shaft 7 is adjusted according to actual needs. The rotating power shaft 7 drives the plug rods 71 ​​to push the central shaft 74 to rotate synchronously, thereby driving the entire partition condensing device to rotate synchronously.

[0028] Embodiment 2 See also Figures 1 to 4 , Figure 6 to Figure 7On the basis of the first embodiment, a fixing ring 72 is welded on the top of the power shaft 7, and the fixing ring 72 is fixedly connected to the support plate 73 by bolts. The fixing ring 72 drives the support plate 73 to rotate synchronously with the power shaft 7, and the height position of the support plate 73 is limited. The top of the support plate 73 is fixedly connected to a circumferentially uniformly distributed pressure spring 14, and the top of the pressure spring 14 is fixedly connected to the bottom end of the water accumulation seat 12. The outer side of the bottom end of the water accumulation seat 12 is fixedly connected to an extension block 15 evenly distributed around the circumference, and a sliding arc surface Ⅰ16 is provided on one side of the extension block 15 protruding out of the water accumulation seat 12 in the circumferential direction.

[0029] See also Figures 1 to 4 , Figure 6 to Figure 7 , a variable ring 17 is fixedly sleeved on the outer bottom of the outer sleeve 1, and a lifting groove 18 evenly distributed around the circumference is provided at the bottom end of the variable ring 17. A sliding arc surface Ⅱ 19 is provided on one side of the lifting groove 18 in the circumferential direction. The sliding arc surface Ⅰ 16 and the sliding arc surface Ⅱ 19 are arranged relatively to each other, so that the water accumulation seat 12 can drive the extension block 15 to rotate synchronously during the rotation process. At this time, the sliding arc surface Ⅰ 16 will be able to contact the sliding arc surface Ⅱ 19, and the top of one side of the extension block 15 protruding from the water accumulation seat 12 will fit with the bottom end of the variable ring 17. At this time, the pressure spring 14 is compressed. When the extension block 15 rotates to the lifting groove 18, the extension block 15 will temporarily lose the upward restriction of the variable ring 17. At this time, the pressure spring 14 will quickly push the water accumulation seat 12 to lift, and then the water accumulation seat 12 continues to drive the extension block 15 to rotate. After the sliding arc surface Ⅰ 16 on the extension block 15 contacts the sliding arc surface Ⅱ 19 in the lifting groove 18, the force When the water seat 12 moves upward rapidly, the volume of the cooling space will be reduced, and the air in the cooling space will be pushed upward at an accelerated speed. When the water seat 12 moves downward slowly, the volume of the cooling space will be increased, and the air in the cooling space will be attracted to move downward, so that the air in the cooling space flows back and forth between the condenser tubes 9, thereby strengthening the natural convection circulation of the above-mentioned gas, prolonging the contact time between the air and the condenser tubes 9 in different areas, improving the turbulent state of the airflow, and further improving the heat exchange effect. When the cooling space is connected to the exhaust port 6, the above-mentioned air movement state will accelerate the discharge of the gas in the cooling space through the exhaust port 6, providing sufficient vacant space for the cooling space to be connected to the intake pipe 2 again to introduce new high-temperature and high-pressure air.

[0030] See also Figure 4There is a gap between the bottom end of the partition condensation plate 8 and the bottom of the movable groove 13. When the water accumulation seat 12 is quickly lifted, the bottom of the movable groove 13 will hit the bottom end of the partition condensation plate 8, so that the partition condensation plate 8 drives the condensation tube 9 to perform impact vibration. The short-term impact vibration will cause the circulating cooling liquid in the partition condensation plate 8 and the condensation tube 9 to fluctuate, thereby increasing the turbulent state of the coolant, thereby increasing the heat exchange capacity of the condensation tube 9 per unit time. The vibration of the partition condensation plate 8 and the condensation tube 9 will cause the liquid condensed on the partition condensation plate 8 and the condensation tube 9 to quickly slide down, gather and drip, thereby accelerating the drainage of the liquid on the partition condensation plate 8 and the condensation tube 9.

[0031] See also Figures 2 to 3 The bottom end of the outer sleeve 1 is higher than the bottom end of the variable ring 17, providing enough space for the extension block 15 to be lifted.
