Description

[0002] An air cooler is an air cooling device that draws in hot air, lowers the temperature of the airflow through built-in refrigeration equipment, and then discharges cold air. Compared with air conditioners, its cooling effect is insufficient, but it consumes less energy and is suitable for cooling regulation at normal temperature.

[0029] 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.

[0030] See also Figures 1 to 8 , the present invention provides a technical solution:

[0031] A separation and purification mechanism for an air cooler includes an inner lining tube 7 installed in the air cooler. The air cooler includes an air inlet rear cover 1 connected to an external air intake pump, a temperature regulating shell 2 for regulating the temperature of the intake air flow, and an exhaust front cover 3 for air outlet. The inner lining tube 7 is installed in the temperature regulating shell 2. The temperature regulating shell 2 is provided with an inner ring plate 16 on the side close to the air inlet rear cover 1. A liquefaction component 10 is installed on the inner ring plate 16. The liquefaction component 10 includes a mesh plate 35. The mesh plate 35 is opposite to the turning bar 18. The sponge scraper 17 on the turning bar 18 is attached to the inner side wall of the mesh plate 35. A card slot 20 for installing the mesh plate 35 is provided on the installation groove 11. The other side of the mesh plate 35 is opposite to the air inlet rear cover 1.

[0032] The mesh plate 35 is fixedly installed by providing the card slot 20, and the mesh plate 35 is connected to the return assembly by means of the mesh plate 35 so that the cold airflow in the return assembly acts on the mesh plate 35. The air inlet pipe 21, the exhaust pipe 33 and the heat dissipation ring pipe 34 are used to enable the cold airflow to fully cool the mesh plate 35, thereby forming a temperature difference between the mesh plate 35 and the inhaled hot airflow. When the hot airflow contacts the mesh plate 35, the water vapor in the airflow is cooled and liquefied and adheres to the mesh plate 35, thereby dehumidifying the hot airflow. At the same time, the rotation of the sponge scraper 17 is used to clean the water droplets adhering to the mesh plate 35, and the impurities adhering to the mesh plate 35 can also be cleaned.

[0033] However, the mesh holes on the mesh plate 35 are relatively large, making it difficult to fully clean the impurities in the airflow, so a filtering and purification component is also designed.

[0034] The inner lining tube 7 is provided with a wiper assembly and a filter purification assembly driven by a motor 5. The motor 5 drives the wiper assembly and the filter purification assembly through a rotating shaft 38. The wiper assembly includes a plurality of groups of rotating strips 18 distributed in a circumferential array installed at the end of the rotating shaft 38. The rotating strips 18 are provided with a plurality of groups of sponge scrapers 17 that are fitted with liquefaction components 10.

[0035] The rotation of the rotating strip 18 drives the sponge scraper 17 to rotate, so that the sponge scraper 17 can clean the mesh plate 35 in a circular rotation manner, and fully absorb the adhered water droplets in the sponge scraper 17 .

[0036] The inner ring plate 16 is provided with a recovery ring groove 8 located outside the mounting groove 11, and the end of the inner liner pipe 7 is provided with a sealing ring plate 23 with a lateral opening for sealing the recovery ring groove 8. The middle of the inner ring plate 16 is provided with a mounting groove 11, and the rotating shaft 38 extends into the mounting groove 11. Multiple groups of turning bars 18 are arranged in the mounting groove 11, and multiple groups of downspouts 22 facing the turning bars 18 are distributed in a circular array on the annular inner wall of the mounting groove 11, and the other side of the downspout 22 is connected to the recovery ring groove 8.

[0037] By rotating the rotating strips 18 , the sponge scraper 17 absorbs the water droplets, and then throws the absorbed water droplets out under the action of the rotating centrifugal force, and drops them along the water droplet 22 into the recovery annular groove 8 , thereby realizing the centralized treatment of the liquefied water flow.

[0038] The filtering and purification component includes a spiral refrigeration strip 13 installed in the middle section of the rotating shaft 38. The spiral refrigeration strip 13 rotates in contact with the inner lining tube 7, and the spiral refrigeration strip 13 is fixedly connected to the rotating shaft 38 through a spiral mesh layer 37 made of metal. A spiral sponge layer 36 is fixedly laid on the side of the spiral mesh layer 37 close to the air inlet rear cover 1. One side of the exhaust front cover 3 is sealed with one end of the inner lining tube 7. An inner plate is provided on the side of the exhaust front cover 3 close to the inner lining tube 7. The motor 5 is fixedly installed on the inner plate. A plurality of through holes are provided on the inner plate facing the filtering and purification component. An air outlet hood 4 is provided on the other side of the exhaust front cover 3.

[0039] By setting up a spiral mesh layer 37, a fixed connection between the rotating shaft 38 and the spiral refrigeration strip 13 is achieved, so that the rotating shaft 38 is used to drive the spiral refrigeration strip 13 to rotate spirally. At the same time, the spiral mesh layer 37 is used to support and fix the spiral sponge layer 36, so that the airflow impacts the spiral sponge layer 36 when passing through the inner cavity of the liner tube 7, thereby filtering and limiting the airflow. The airflow filtration efficiency of the spiral sponge layer 36 is low, so it will cause the problem of increased airflow internal pressure in the spiral inner cavity. At this time, impurities in the airflow fall on the spiral sponge layer 36 under the action of positive internal pressure, avoiding suspension in the airflow, achieving sufficient purification treatment, and under spiral rotation, the airflow can be discharged stably, and the continuous increase of air pressure is avoided.

[0040] Working principle: First, the hot air flow is sucked in by the pump machine connected to the air inlet rear cover 1, and the air flow impacts the mesh plate 35. The water vapor in the air flow is cooled and liquefied to form water droplets adhering to the mesh plate 35. The wet mesh plate 35 can also increase the effect of adsorbing particulate impurities in the air flow, and the rotating sponge scraper 17 is used to clean the water droplets and impurities. The air flow after dehumidification and preliminary separation impacts the spiral sponge layer 37, and the spiral sponge layer 37 is used to clean the suspended impurities in the air flow. The air flow filtration efficiency of the spiral sponge layer 36 is low, so it will cause the problem of increased air flow internal pressure in the spiral cavity. At this time, the impurities in the air flow fall on the spiral sponge layer 36 under the action of the positive internal pressure. As the spiral sponge layer 36 is filtered and blocked, the air flow efficiency is further reduced, the positive pressure increases, and the purification effect of suspended impurities in the air flow is better, and the spiral rotation can avoid excessive air flow internal pressure, thus forming a positive cycle.

[0041] Example 2: On the basis of Example 1, the liquefaction component 10 also includes an intake pipe 21, an exhaust pipe 33 and a heat dissipation ring pipe 34. The intake pipe 21 and the exhaust pipe 33 distributed above and below are respectively installed in the card slot 20, wherein the intake pipe 21 is connected to the reflux component, and one end of the exhaust pipe 33 is connected to the intake pipe 21 through the heat dissipation ring pipe 34. The heat dissipation ring pipe 34 is distributed on the mesh plate 35. The other end of the exhaust pipe 33 is connected to the recovery ring groove 8 and is connected to the inner cavity of the lining pipe 7 through the downspout 22. A reflux component for cooling the liquefaction component 10 is provided on the exhaust front cover 3. The reflux component includes a reflux port 6 and a reflux pipe 15 provided on the exhaust front cover 3. The reflux pipe 15 connects the reflux port 6 and the intake pipe 21, and the reflux pipe 15 is connected to the intake pipe 21 in the lower end inner cavity of the recovery ring groove 8.

[0042] The prepared cold air flow is directed to the liquefaction component 10 by using the reflux component to cool the mesh plate 35 so that the air flow is cooled and liquefied, thereby achieving the purpose of dehumidification.

[0043] An anti-overflow groove 19 is provided on the mounting groove 11, a sponge strip 9 is provided in the recovery ring groove 8, and a conical guide block 12 is provided at the end of the rotating shaft 38, which passes through the mesh plate 35. The guide block 12 is facing the air inlet rear cover 1, and the anti-overflow groove 19 is provided on the outer side of the mesh plate 35 close to the air inlet rear cover 1, and the lower end of the anti-overflow groove 19 is connected to the lower end inner cavity of the recovery ring groove 8. The sponge strip 9 is provided on the upper arc-shaped inner wall of the recovery ring groove 8, and the thickness of the sponge strip 9 is less than half of the width between the grooves of the recovery ring groove 8.

[0044] The water droplets on the other side of the mesh plate 35 will gather and fall. By setting the anti-overflow groove 19, the water droplets on the other side of the mesh plate 35 will be concentrated and collected and recovered in the recovery ring groove 8. Since the water droplets in the sponge scraper 17 impact the inner wall of the recovery ring groove 8 under the action of centrifugal force, in order to prevent the water droplets impacting the inner wall of the upper end of the recovery ring groove 8 from dripping again due to gravity, the sponge strip 9 is designed to absorb the water droplets impacting the inner wall of the upper end of the recovery ring groove 8. The refluxed gas enters the recovery ring groove 8 again through the exhaust pipe 33, which increases the internal pressure of the recovery ring groove 8, so that the fully absorbed sponge strip 9 is squeezed by the air pressure, and the absorbed water droplets are pressed out and fall along the inner wall of the recovery ring groove 8. The airflow in the recovery ring groove 8 flows back to the inner lining pipe 7 under the action of the downspout 22 and the rotating strip 18, and realizes re-refrigeration filtration; the guide block 12 is used to slow down the impact of the inhaled airflow, realize lateral guide, improve the protection of the mesh plate 35, and avoid deformation.

[0045] Example 3: Based on Example 2, in order to avoid leakage of cold air during liquefied dehumidification drainage, a drain port 24 is provided at the lower end of the recovery ring groove 8, and one end of the U-shaped drain pipe 14 is connected to the recovery ring groove 8 through the drain port 24, and the other end of the U-shaped drain pipe 14 extends to the outside of the temperature control shell 2, and the outer port of the U-shaped drain pipe 14 is located at the lower end of the recovery ring groove 8.

[0046] A liquid-sealed drainage pipe is realized by providing the U-shaped drainage pipe 14 , and the accumulated water droplets fall into the U-shaped drainage pipe 14 , forming a liquid level difference.

[0047] A pressure-adjustable piston float rod 25 is provided on the outer port of the U-shaped drain pipe 14, a side port 28 for drainage is provided through the side wall of the outer port of the U-shaped drain pipe 14, and a wing ring 27 is provided on the outer wall of the upper end of the outer port of the U-shaped drain pipe 14.

[0048] In order to maintain the liquid level balance, the outer liquid level rises to the position of the side port 28, thereby achieving the purpose of liquid sealing and drainage, and avoiding cold air leakage.

[0049] An adjustment frame 26 is provided on the outer wall of the temperature control shell 2, facing the outer port of the U-shaped drain pipe 14. A screw 31 is threadedly installed on the adjustment frame 26, and a crossbeam 30 is rotatably installed on the bearing at the lower end of the screw 31. Pressure rods 32 are symmetrically provided on both sides of the crossbeam 30. The upper end of the pressure rod 32 slides through the adjustment frame 26, and a spring 29 is pressed between the lower end of the pressure rod 32 and the wing ring 27.

[0050] Since the inside of the U-shaped drain pipe 14 is not only affected by the liquefied water flow, but also by the internal air pressure of the air cooler, which causes the liquid surface inside the U-shaped drain pipe 14 to be squeezed, it is easy for the internal pressure to be too high to overcome the gravity of the water flow, resulting in the problem that the water flow cannot be liquid-sealed in the bending section of the U-shaped drain pipe 14. Therefore, a piston float rod 25 is designed, and the screw 31 and the spring 29 are used to adjust the downward pressure of the piston float rod 25 to offset the internal air pressure of the air cooler, thereby achieving a stable liquid-sealed drainage effect.

[0051] 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.
