[0001] This utility model relates to the field of air conditioning technology, and in particular to an ultra-thin chilled water air conditioner. Background Technology

[0002] Chilled water air conditioning is a configuration option for data center computer room air conditioning. Its flexible cooling capacity, high efficiency and low energy consumption have made it a popular choice for many data center projects. Chilled water air conditioning typically consists of core components such as surface coolers, fans, two-way regulating valves and air filters.

[0003] In existing technologies, chilled water server room air conditioning designs mostly adopt an integrated structure, deeply integrating core components such as fans, two-way valves, and filters into the air conditioning unit. This type of structure has significant limitations during equipment maintenance. Before maintenance, a complete shutdown and removal of the equipment panel or part of the outer casing are required to access the internal components. In particular, fans are usually installed deep within the air conditioning unit, requiring the additional removal of surface cooler baffles or piping during maintenance. This cumbersome and complex process not only consumes significant time and manpower but also carries the risk of damaging surrounding components. Furthermore, the integrated structure lacks redundancy. If a fan fails, the entire unit must be shut down for maintenance, making it difficult to maintain stable cooling output during fan maintenance. This severely impacts the operational reliability of applications such as data centers, which have extremely high requirements for continuous cooling.

[0004] Therefore, there is an urgent need to develop an ultra-thin chilled water air conditioner to solve the above problems. Utility Model Content

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] The purpose of this utility model is to provide an ultra-thin chilled water air conditioner to solve the problem that the entire air conditioner needs to be shut down for maintenance when any fan malfunctions, thereby achieving the effect of maintaining a stable output of cooling capacity during fan maintenance.

[0043] Specifically, such as Figures 1 to 11As shown, a chilled water ultra-thin air conditioner includes a controller, a plug-in structure, a fan module 1, and a piping structure 2. The plug-in structure includes a plug and a socket. One end of the socket is electrically connected to the controller, and the plug can be plugged into the socket. There are at least two fan modules 1. Each fan module 1 includes a fixed plate 11 and a fan 12. The fan 12 is connected to the fixed plate 11, and the input end of the fan 12 is connected to the plug. The controller can control the speed of the fan 12. The piping structure 2 includes a fan coil unit and a two-way valve 22. Chilled water can flow in the fan coil unit through the two-way valve 22. The fan coil unit includes a return water pipe 21. The two-way valve 22 includes a valve body 221 and an actuator 222. The valve body 221 is installed on the return water pipe 21, and the actuator 222 is signal-connected to the controller. The actuator 222 can adjust the opening degree of the valve body 221. The air conditioner is divided into at least two fan modules 1, each containing a fan 12 whose speed can be individually controlled by a controller. When a fan 12 malfunctions, the plug connected to that fan 12 is unplugged, allowing the entire fan module 1 to be removed from the air conditioner for maintenance. The remaining fan modules 1 continue operating, thus enabling maintenance of the fan 12 without shutting down the air conditioner. Furthermore, the controller increases the speed of the continuously operating fan 12 to improve airflow, and controls the actuator 222 to increase the opening of the valve 221 to increase the chilled water flow. This maintains a stable cooling output during fan 12 maintenance, effectively preventing temperature fluctuations in the server room caused by air conditioner maintenance. In this embodiment, there are 5 fan modules 1; in other embodiments, there are 2, 4, or 6 fan modules 1, etc.

[0044] Furthermore, such as Figures 5 to 8 As shown, each fan module 1 includes at least two fans 12, reducing the number of fan modules 1, thereby reducing the production cost of the fan modules 1 included in the entire air conditioner, and thus reducing the overall production cost of the air conditioner. In this embodiment, each fan module 1 includes three fans 12; in other embodiments, each fan module 1 may include two fans 12 or four fans 12.

[0045] Optionally, the fan module 1 also includes a handle 13, which is fixedly connected to the side surface of the fixing plate 11. The fan module 1 can be easily removed by grasping the handle 13. Furthermore, there are two handles 13, which are respectively installed on both sides of the fixing plate 11 of the fan 12, so as to facilitate the operation of the operator with both hands and improve work efficiency.

[0046] Optionally, such as Figures 9 to 13As shown, the pipeline structure 2 also includes a clamp 23. Quick-connect fittings 231 are provided at both ends of the valve body 221. Along the axial direction of the return water pipeline 21, a first flange 232 is provided at the end of the quick-connect fitting 231 furthest from the valve body 221. A second flange is provided on the return water pipeline 21. The first flange 232 and the second flange are tightly connected by the clamp 23. The clamp 23 secures the second flange and the first flange 232, achieving a sealed connection between the two-way valve 22 and the return water pipeline 21. When the two-way valve 22 needs maintenance, it can be quickly replaced by disassembling the clamp 23, improving maintenance efficiency. It should be noted that the clamp 23 is a commonly used structural component for connecting pipelines in the prior art, and will not be described in detail here.

[0047] Furthermore, the clamp 23 is made of a high-strength material, possessing high strength and toughness, and can provide a strong clamping force to tightly connect the first flange 232 and the second flange together, effectively preventing loosening and leakage at the connection point. While ensuring ease of maintenance, it also guarantees the stability of the pipeline under high water pressure conditions. In this embodiment, the clamp 23 is made of stainless steel; in other embodiments, the clamp 23 is made of carbon steel.

[0048] Optionally, such as Figures 3 to 4 As shown, the ultra-thin chilled water air conditioner also includes a filter structure 4 and an air conditioner housing 3. The filter structure 4 includes a filter screen 41, which is installed on the air inlet side of the fan 12 and connected to the outer surface of the air conditioner housing 3. The filter screen 41, installed on the air inlet side of the fan 12, filters dust, impurities, and other particulate matter in the air, providing clean air to the fan 12 and protecting its normal operation. Furthermore, by installing the filter screen 41 on the outer surface of the air conditioner housing 3, it can be directly cleaned, inspected, or replaced without opening the housing or performing complex disassembly operations, making filter screen 41 maintenance more convenient and saving maintenance time and labor costs.

[0049] Furthermore, the filter 41 is detachably connected to the air conditioner housing 3. When the filter 41 needs maintenance, a new filter 41 can be replaced without affecting the normal use of the air conditioner, thereby improving the working efficiency of the air conditioner.

[0050] Furthermore, the filter structure 4 also includes a wing screw 42. The filter screen 41 includes a filter screen frame 411 and a filter screen body 412. The filter screen frame 411 and the filter screen body 412 are fixedly connected around the perimeter. The wing screw 42 is threadedly connected to the air conditioner housing 3. Along the axial direction of the wing screw 42, the head of the wing screw 42 faces the side of the air conditioner housing 3 and abuts against the filter screen frame 411. By manually turning the head of the wing screw 42 perpendicular to the side of the filter screen frame 411, the filter screen frame 411 is locked, thus connecting the filter screen frame 411 to the air conditioner housing 3. When the filter screen 41 is under maintenance, the wing screw 42 is manually turned in the opposite direction to make the head of the wing screw 42 parallel to the side of the filter screen frame 411, and the filter screen frame 411 can be removed. The entire process can be completed quickly without the aid of any tools. In other embodiments, a slot may be provided on one of the air conditioner housing 3 and the filter frame 411, and a buckle may be provided on the other. The buckle engages with the slot to achieve a detachable connection between the filter frame 411 and the air conditioner housing 3.

[0051] Furthermore, the filter structure 4 also includes a screwing component 43, which is connected to the head of the wing screw 42. Along the axial direction of the wing screw 42, the side of the screwing component 43 facing the filter frame 411 can abut against the side surface of the filter frame 411, further improving the fixing effect on the filter frame 411. The screwing component 43 enlarges the wing structure of the wing screw 42 head, making it easier for workers to access the wing screw 42, further improving the convenience of screwing the wing screw 42.

[0052] Optionally, the number of filters 41 is at least two, and at least two filters 41 are inspected simultaneously to improve the inspection efficiency of the filters 41. In this embodiment, the number of filters 41 is three; in other embodiments, the number of filters 41 can be two, four, or five, etc.

[0053] Furthermore, there are multiple wing screws 42 and screw-on parts 43, and they correspond one-to-one. The wing screws 42 are distributed on both sides of the filter frame 411 to improve the fixing stability of the filter frame 411. In this embodiment, there are 4 wing screws 42 and 43 screw-on parts. In other embodiments, there are 3, 5 or 6 wing screws 42 and screw-on parts 43, etc.

[0054] Optionally, the filter 41 is a pull-out filter 41. The pull-out design allows the filter 41 to be easily pulled out from the air conditioner housing 3, eliminating the need for a complicated disassembly process and enabling cleaning, rinsing, or replacement of the filter 41, thus greatly saving maintenance time and labor costs. In other embodiments, the filter 41 can also be a plug-in filter 41.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
