Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a water receiving device and air conditioning equipment. Background Technology

[0002] To prevent damage to electronic components from static electricity generated or present in data centers, strict requirements are placed on the temperature and humidity of the server room. Currently, to meet energy-saving requirements, data centers often employ high return air operation, using natural cooling or high-temperature chilled water systems to control the server room temperature. However, these terminal air conditioners lack humidity control capabilities and cannot meet the increasing humidity control demands of data centers. Therefore, data centers need to be equipped with additional humidity control equipment to maintain stable humidity within the server room. The reliability of humidity control equipment is extremely important, especially regarding water inlet and drainage. Due to the pressure difference across the wet film and heat exchanger, the circulating water and dehumidifying condensate in the wet film are carried away by airflow, leading to poor drainage of the water tank and causing problems such as water blowing and bubbling, posing safety hazards to surrounding electronic components.

[0022] Before describing the embodiments in detail, it should be understood that this application is not limited to the detailed structures or element arrangements described below or in the accompanying drawings. This application can be implemented in other ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes only and should not be construed as limiting. The terms "comprising," "including," "having," and similar expressions used herein mean to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "an element," this application does not limit the number of elements to one, but may include multiple elements.

[0023] like Figure 1-3As shown, this application provides a water receiving device 11, which is applicable to air conditioning devices such as air conditioning equipment 10, wherein the air conditioning equipment can be a humidity control device or a temperature control device. Specifically, the water receiving device 11 includes a first water receiving tray 22, a second water receiving tray 24, and a water tank 20. The water tank 20 includes a first housing 36 and a second housing 38 connected to the upper part of one side of the first housing 36. The second housing 38 communicates with the first housing 36. The first water receiving tray 22 is disposed in the second housing 38, and the bottom of the second water receiving tray 24 is disposed in the upper part of the first housing 36. The first water receiving tray 22 and the second water receiving tray 24 are respectively communicated with the interior of the first housing 36. By setting up independent first water receiving trays 22 and second water receiving trays 24, the two water receiving trays can be used to collect water for different components, and the collected water flows into the water tank 20 respectively, so that the water tank 20 can be filled and drained smoothly.

[0024] like Figure 5 As shown, this application also provides an air conditioning device 10, which can be used to regulate air humidity in environments such as computer rooms and data centers that employ water-cooled temperature control systems. The air conditioning device 10 includes a casing 12 and a humidification unit 14, a heat exchange unit 16, a water treatment system, an electrical control box, and a fan 18 disposed within the casing 12. The water treatment system includes a water pump assembly and a water receiving device 11. The humidification unit 14 is, for example, a wet film humidifier, and the heat exchange unit 16 is, for example, a heat exchanger equipped with a compressor. A first water receiving tray 22 is used to install the humidification unit 14 and collect the circulating water from the humidification unit 14. A second water receiving tray 24 is used to collect condensate generated on the outer surface of the heat exchange unit 16. The first and second water receiving trays 22 and 24 are respectively connected to a water tank 20 to drain the water collected in the first and second water receiving trays 22 and 24 into the water tank 20. The water pump assembly is used to pump the water from the water tank 20 to the humidification unit 14. By setting up independent first water receiving tray 22 and second water receiving tray 24, the water tank 20 can be filled and drained smoothly. At the same time, the humidification unit 14 and the heat exchange unit 16 can be disassembled and maintained separately without affecting the overall unit structure. After the water receiving tray is removed, the water tank 20 can be maintained from the front, which improves the high reliability of humidity control and the maintainability of the device.

[0025] In the illustrated embodiment, a mounting cavity 26 is formed within the housing 12. A fan 18 is located at the top of the mounting cavity 26. For example, a partition 28 is provided on the top side of the mounting cavity 26, dividing the mounting cavity 26 into upper and lower parts. The fan 18 is installed in the upper part of the mounting cavity 26, while the humidification unit 14, heat exchange unit 16, water treatment system, and electrical control box are all located in the lower part of the mounting cavity 26. The housing 12 includes a side end plate with an air inlet and an air outlet. The air inlet can be located in the area of ​​the side end plate corresponding to the lower part of the mounting cavity 26, and the air outlet can be located in the area of ​​the side end plate corresponding to the upper part of the mounting cavity 26. The airflow field generated by the operation of the fan 18 forms an airflow channel between the air inlet and the air outlet. The humidification unit 14 and the heat exchange unit 16 are both located along the path of the airflow channel. After entering the mounting cavity 26 through the air inlet, the outside air can be humidified by the humidification unit 14 or dehumidified by the heat exchange unit 16. The humidified or dehumidified air is blown out through the air outlet through the air channel, thereby realizing the regulation and control of the air humidity in the outside space and achieving the effect of humidification or dehumidification.

[0026] In this embodiment, both the humidification unit 14 and the heat exchange unit 16 are located below the fan 18. The humidification unit 14 is located between the heat exchange unit 16 and the side end plate, that is, the humidification unit 14 is located on the side near the air inlet.

[0027] The water pump assembly includes a water pump 30, a connecting pipe 32, and a spray head 34. The spray head 34 is located above the humidification unit 14 to spray water onto the humidification unit. The connecting pipe 32 connects the water tank 20 and the spray head 34. The water pump 30 is located on the connecting pipe 32 to pump water from the water tank 20 to the spray head 34.

[0028] Please also refer to Figure 6 and Figure 7 As shown, the water tank 20 includes a first tank body 36 and a second tank body 38 extending outward from the upper side of one side of the first tank body 36, wherein the first tank body 36 and the second tank body 38 are internally connected. A first water receiving tray 22 is disposed inside the second tank body 38 and partially extends to the upper part of the first tank body 36, and a second water receiving tray 24 is disposed on the upper part of the first tank body 36, and both the first water receiving tray 22 and the second water receiving tray 24 are internally connected to the first tank body 36. A humidification unit 14 is disposed above the first water receiving tray 22, and a heat exchange unit 16 is disposed above the second water receiving tray 24.

[0029] The humidification unit 14 and the heat exchange unit 16 are independent of each other in terms of water addition, drainage, disassembly, and maintenance. Disassembly and maintenance of the humidification unit 14 and the heat exchange unit 16 separately will not affect other structures of the unit. The humidification unit 14 is placed on the first water receiving tray 22, so that water that has not been completely evaporated from the humidification unit 14 can flow directly into the first water receiving tray 22; the heat exchange unit 16 is placed on the second water receiving tray 24, so that condensate generated on the outer surface of the heat exchange unit 16 during the heat exchange process can flow directly into the second water receiving tray 24.

[0030] If the unit has not been humidified for an extended period, or if it has not been operated for a long time, the water in the tank should be drained promptly to prevent bacterial growth and scale buildup. Some designs incorporate a tank cleaning function; after a set humidification time, the drain valve opens to drain the water. However, the drain hole is typically located at the bottom of the tank, and the rapid water flow during drainage can easily create eddies, leading to poor drainage. This application incorporates a pressure equalization device. This device slows down the water flow, preventing eddies and also helps to block scale buildup.

[0031] Specifically, please also refer to Figure 2 and Figure 5 As shown, the water treatment system also includes a pressure equalization device 44. A third drain hole 46 is provided at the bottom of the first housing 36, and one end of the connecting pipe 32 is connected to the third drain hole 46. The pressure equalization device 44 is located on the top side of the third drain hole 46. More specifically, a first water receiving tray 22 is located inside the second housing 38 and partially extends to the upper part of the first housing 36. A first drain hole 48 is provided at the bottom of the area of ​​the first water receiving tray 22 corresponding to the area of ​​the first housing 36. A second drain hole 50 is provided at the bottom of the second water receiving tray 24. The first water receiving tray 22 and the second water receiving tray 24 are connected to the interior of the first housing 36 through the first drain hole 48 and the second drain hole 50, respectively. The pressure equalization device 44 is located on the bottom side of the first drain hole 48 and the second drain hole 50 and fixed to the upper end of the corresponding corner side wall of the first box 36, so that the first drain hole 48 and the second drain hole 50 are both located inside the pressure equalization device 44. The water discharged from the first drain hole 48 and the second drain hole 50 can flow directly into the pressure equalization device 44 and then be discharged into the first box 36 through the pressure equalization device 44.

[0032] In this embodiment, as Figure 4As shown, the pressure equalization device 44 includes a pressure equalization plate 52 and a mesh structure 54 disposed on the pressure equalization plate 52. The pressure equalization plate 52 and at least two adjacent side walls of the first box 36 form a square box. The first drainage hole 48 and the second drainage hole 50 are both connected to the interior of the square box. The pressure equalizing plate 52 comprises three adjacent and perpendicular plates. The pressure equalizing plate 52 and the two adjacent side walls of the first housing 36 form an upward-opening square housing. The first drain hole 48 and the second drain hole 50 are both connected to the interior of the square housing, so that the water in the pressure equalizing device 44 can be discharged into the first housing 36 through the mesh structure 54 after pressure equalization treatment. Alternatively, the pressure equalizing plate 52 comprises one adjacent and perpendicular L-shaped plate. The pressure equalizing plate 52 and the two adjacent side walls and bottom of the first housing 36 form an upward-opening square housing. The first drain hole 48 and the second drain hole 50 are both connected to the interior of the square housing, so that the water in the pressure equalizing device 44 can be discharged into the first housing 36 through the mesh structure 54 after pressure equalization treatment. The mesh structure 54 can be set as a through hole on the pressure equalizing plate 52. The size and height of the through hole can be set according to the actual application scenario and are related to the water flow of the two water receiving trays and the size of the pressure equalizing plate 52 and the first housing 36. In other embodiments, the pressure equalization device 44 may also have other structural designs to balance pressure and avoid eddies, as long as it can achieve functions such as slowing down the water flow speed, avoiding eddies, and blocking dirt.

[0033] During the humidification process, the humidification unit 14 inevitably causes impurities to accumulate in the water tank 20. To prevent impurities from flowing into the water pump 30 through the drain hole 46 at the bottom of the water tank 20 and accumulating inside the water pump 30, thus burning it out, the height of the end hole of the third drain hole 46 located inside the first housing 36 can be set to be a certain distance higher than the bottom plate of the first housing 36, thereby preventing impurities from entering the third drain hole 46. It should be understood that other designs that prevent impurities from flowing into downstream devices and equipment by increasing the height of the third drain hole 46 inside the water tank 20 are within the scope of protection of this application.

[0034] Specifically, the first water receiving tray 22 and the second water receiving tray 24 are arranged side by side at intervals along the width direction of the water tank 20. The first water receiving tray 22 includes a first base plate 56 and first flanges 58 connected to opposite ends of the first base plate 56 and extending upward. The first base plate 56 covers the entire second tank body 38. The two first flanges 58 are used to limit the width of the first water receiving tray 22. The two first flanges 58 are located in the interval direction between the first water receiving tray 22 and the second water receiving tray 24, and one of the first flanges 58 is disposed against the inner wall of the second tank body 38, while the other first flange 58 is located on the upper part of the first tank body 36. The first water receiving tray 22 can be detachably fixed to the second housing 38 by means of screws or the like. The first base plate 56, the two first folded edges 58 and the inner wall of the second housing 38 together form a trough structure for holding the circulating water of the humidification unit 14. The design of the two first folded edges 58 can facilitate the installation of the humidification unit 14 and the holding of the circulating water of the humidification unit 14. In addition, the fact that only two first folded edges 58 are provided can also facilitate the disassembly, maintenance and replacement of the humidification unit 14.

[0035] Preferably, the two first folded edges 58 are inclined outward relative to the first base plate 56, such that the distance between the bottom ends of the two first folded edges 58 is smaller than the distance between their top ends. This increases the water collection area and improves the water collection rate of the first water receiving tray 22.

[0036] Furthermore, the first water receiving tray 22 has a partition 23 within its groove structure. The humidifying unit 14 is placed on the partition 23, and a space 25 is formed between the partition 23 and the first base plate 56 of the first water receiving tray 22. The partition 23 has several drain holes 27, and the first drain hole 48 is located on the first base plate 56. Due to the large water flow of the humidifying unit 14, the circulating water of the humidifying unit 14 first falls onto the partition 23, then flows into the space 25 through the drain holes 27, and finally is discharged into the pressure equalization device 44 through the first drain hole 48. After pressure equalization treatment, it is discharged into the first housing 36. This sandwich design of the first water receiving tray 22 can further slow down the water flow rate and enhance the smoothness of water addition and drainage.

[0037] The second water receiving tray 24 includes a second base plate 60, and a second flange 62, a first flange 66, and a second flange 67 respectively connected to the second base plate 60. The second flange 62 is located on one side of the second water receiving tray 24 in the width direction, while the first flange 66 and the second flange 67 are located on both sides of the second water receiving tray 24 in the length direction. The second flange 62 is connected to the side of the second base plate 60 near the first water receiving tray 22 and extends upward relative to the second base plate 60. The first flange 66 and the second flange 67 both extend upward relative to the second base plate 60 and are used to install and fix the second water receiving tray 24 to the upper part of the first housing 36. The first flange 66 and the second flange 67 are, for example, L-shaped flanges. The first flange 66 and the second flange 67 can be attached to and hung on the side wall of the first housing 36 and can be detached and installed by means of screws or other methods.

[0038] The second water receiving tray 24 is also provided with an extension 64 connected to the second base plate 60. The extension 64 is connected to the side of the second base plate 60 away from the first water receiving tray 22 and extends downward relative to the second base plate 60. The extension 64 covers at least half of the distance between the second water receiving tray 24 and the side wall of the first housing 36 away from the second housing 38. The extension 64 is designed to extend in the direction of the wind to prevent uneven local wind speed from causing the water tank 20 to be blown backward, and to blow the water in the water tank 20 out sequentially. In some embodiments, the extension 64 may also cover the entire space between the second water receiving tray 24 and the side wall of the first housing 36 away from the second housing 38, and all condensate flows into the water tank 20 through the second drain hole 50; the extension 64 may also cover part of the space between the second water receiving tray 24 and the side wall of the first housing 36 away from the second housing 38, which can reverse the airflow and collect water droplets carried in the air.

[0039] In order to increase the structural strength of the water tank 20 and avoid bending and deformation of the side plate of the water tank 20 due to excessive length of one side, the water tank 20 is made of sheet metal. The upper end of the side wall of the first tank 36 away from the second tank 38 is also provided with a third folded edge 68 that bends towards the second tank 38. The third folded edge 68 is, for example, perpendicular to the side wall of the water tank 20.

[0040] In this application, the side end plate can be designed to be detachable or rotatable, facilitating the maintenance of internal components. In particular, the humidification unit 14 is independently installed near the side end plate, so the humidification unit 14 can be removed independently without affecting other structures of the unit. After removing the humidification unit 14, the water tank 20 can be maintained from the front, facilitating the maintenance and replacement of the internal structure of the water tank 20. The structure is simple and easy to operate.

[0041] In humidification mode, heat exchange unit 16 is not working. External air enters the airflow channel through the air inlet. The operation of fan 18 creates a negative pressure state in the area where humidification unit 14 is located. The air is drawn towards humidification unit 14 and becomes humid air with higher humidity. The water that has not evaporated completely on humidification unit 14 slides onto the partition 23 in the first water receiving tray 22. It flows into the partition space 25 through the drain hole 27 on the partition 23, and then through the first drain hole 48 to the pressure equalization device 44 for pressure equalization treatment. The water after pressure equalization treatment is discharged into the first box 36 of water tank 20 through the mesh structure 54 of pressure equalization device 44, avoiding water accumulation in the first water receiving tray 22 and causing poor drainage. The humid air is drawn by fan 18 and flows along the airflow channel to the air outlet and is discharged into the external space, achieving the humidification effect.

[0042] In dehumidification mode, the humidification unit 14 and its spray device are not working. External air enters the airflow channel through the air inlet and then flows to the evaporator of the heat exchange unit 16. The liquid refrigerant in the evaporator vaporizes when it encounters hot air and absorbs the heat of the air to dehumidify it. At this time, some wet vapor will condense into water on the hydrophilic fins. After the water accumulates, it falls into the second water receiving tray 24 under the action of gravity. The second drain hole 50 and the downward-sloping extension 62 of the second water receiving tray 24 can make the water in the second water receiving tray 24 drain quickly, avoiding water accumulation in the second water receiving tray 24 and causing poor drainage. The water discharged through the second drain hole 50 enters the pressure equalization device 44 for pressure equalization treatment. After pressure equalization treatment, the water is discharged into the first box 36 of the water tank 20 through the mesh structure 54 of the pressure equalization device 44. The dehumidified air flows to the external space through the air outlet through the air channel, achieving the dehumidification effect.

[0043] In summary, this application provides a water receiving device and an air conditioning unit. The water receiving device includes a first water receiving tray, a second water receiving tray, and a water tank. The water tank includes a first housing and a second housing connected to the upper part of one side of the first housing. The second housing communicates with the first housing. The first water receiving tray is located in the second housing, and the bottom of the second water receiving tray is located in the upper part of the first housing. Both the first and second water receiving trays are connected to the interior of the first housing. By providing independent first and second water receiving trays, the two trays can be used to collect water for different components. After water is collected, it flows into the water tank, ensuring smooth water filling and drainage. This improves the reliability of the air conditioning unit in humidity control and enhances the maintainability of the equipment.
