Description

Technical Field

[0001] This application relates to the field of heat dissipation technology, and in particular to air conditioning and heat dissipation systems. Background Technology

[0002] With the rapid development of big data, cloud computing, and other industry technologies, and the launch of the national "Eastern Data, Western Computing" project, data centers are growing in scale. As major energy consumers, data centers have increasingly higher requirements for energy conservation and consumption reduction in their cooling systems. Currently, in-row (column) air conditioners are commonly used as a solution for air cooling in data centers. However, in the use of some small-sized in-row (column) air conditioners, condensate will be generated on the heat exchanger pipes inside the air conditioner. If the system's condensate drainage is not considered, it will pose a safety hazard to the data center and affect its safe operation. At present, there are many ways to arrange air conditioning systems in the industry, which are relatively complex in structure, have low space utilization, are not obvious in effect, and have high manufacturing difficulty and subsequent maintenance costs. Utility Model Content

[0003] Therefore, it is necessary to provide an air conditioner that addresses the problem of difficult condensate drainage in the use of small-sized inter-row (column) air conditioners, which poses a safety hazard to data centers and affects their safe operation.

[0004] An air conditioner comprising:

[0005] Base plate;

[0006] A water receiving tray, which is installed on the base plate;

[0007] A heat exchanger, which is installed on the water receiving pan;

[0008] A fan is provided, spaced apart from the heat exchanger; and the fan is located on one side of the air outlet of the air conditioner.

[0009] A liquid separator is disposed between the heat exchanger and the fan; and the liquid separator is connected to the heat exchanger.

[0010] Wherein, the outer contour of the water receiving tray along the direction of gravity is located outside the outer contour of the liquid dispenser along the direction of gravity.

[0011] In one embodiment, the dispenser is provided with a plurality of spaced-apart dispensing tube interfaces;

[0012] Along the airflow direction of the air conditioner, the heat exchanger has multiple spaced heat exchange tubes on the side opposite to the air inlet.

[0013] Each of the liquid distribution tube interfaces is connected to one of the heat exchange tubes.

[0014] In one embodiment, a plurality of the dispensing tube interfaces are distributed at equal intervals along the circumference of the dispenser.

[0015] In one embodiment, the air conditioner further includes a plurality of capillaries, each capillary being connected between one of the liquid distribution pipe interfaces and one of the heat exchange tubes;

[0016] The outer contour of the water receiving tray, projected along the direction of gravity, is located outside the outer contour of the capillary tube, projected along the direction of gravity.

[0017] In one embodiment, the outer contour of the water receiving tray as a positive projection along the direction of gravity is located outside the outer contour of the heat exchanger as a positive projection along the direction of gravity.

[0018] In one embodiment, the heat exchanger is arranged diagonally along the water receiving pan.

[0019] In one embodiment, the side of the fan away from the heat exchanger is also provided with an openable and closable opening;

[0020] The air conditioner also includes an openable and closable door, which is installed at the openable and closable opening and is used to open or close the openable and closable opening.

[0021] In one embodiment, the air conditioner further includes an electronic expansion valve installed between the fan and the distributor.

[0022] In one embodiment, the air conditioner further includes a wet film, which is installed on the side of the heat exchanger opposite to the distributor;

[0023] The wet membrane is detachably connected to the heat exchanger.

[0024] This application also provides a heat dissipation system, which includes the air conditioner described in any of the above embodiments, and can solve at least one of the above technical problems.

[0025] When using the aforementioned air conditioning and cooling system for air-cooled heat dissipation, the distributor is positioned between the heat exchanger and the fan, with the fan located on the air outlet side of the air conditioner. Therefore, the distributor is positioned on the side away from the air inlet. This arrangement prevents the distributor from obstructing the airflow at the air inlet, thus eliminating the need for excessively large heat exchangers and base plates. The overall structure of the air conditioner is more compact, the layout more rational, and space utilization is higher. Furthermore, since the outer contour of the condensate tray along the direction of gravity is located outside the outer contour of the distributor along the direction of gravity, all condensate on the pipes connecting the distributor and the heat exchanger during air-cooled heat dissipation is collected in the condensate tray for processing. This makes the operation of the air conditioner safer, thereby enhancing the safety of the data center equipped with this air conditioner, reducing the risk of water damage and minimizing safety hazards.

[0037] See Figure 1-Figure 3 , Figure 1 A first schematic diagram of the internal structure of an air conditioner provided in some embodiments of this application is shown. Figure 2 Shown Figure 1 The second schematic diagram shows the internal structure of the air conditioner. Figure 3 Shown Figure 1 The image shows a top view of an air conditioner. An embodiment of this application provides an air conditioner including a base plate 100, a heat exchanger 200, a fan 300, a distributor 400, and a drip tray 500. The drip tray 500 is mounted on the base plate 100; the heat exchanger 200 is mounted on the drip tray 500; the fan 300 is spaced apart from the heat exchanger 200 and is located on one side of the air outlet 1920 of the air conditioner; the distributor 400 is located between the heat exchanger 200 and the fan 300 and is connected to the heat exchanger 200; the outer contour of the drip tray 500 along the direction of gravity is located outside the outer contour of the distributor 400 along the direction of gravity; specifically, the direction of gravity is... Figure 1 and Figure 2 The direction of zz' in the middle.

[0038] When the above-mentioned air conditioner is used for air cooling, since the distributor 400 is located between the heat exchanger 200 and the fan 300, and the fan 300 is located on the side of the air outlet 1920 of the air conditioner, the distributor 400 is also located on the side away from the air inlet 1910 of the air conditioner. This arrangement makes it less likely for the distributor 400 to block the airflow at the air inlet 1910. Therefore, it is not necessary to design the size of the heat exchanger 200 and the base plate 100 of the entire air conditioner to be too large. The structure of the entire air conditioner is more compact, the layout is more reasonable, and the space utilization rate is higher. Furthermore, since the outer contour of the water collection tray 500 along the direction of gravity is located on the outer periphery of the outer contour of the liquid distributor 400 along the direction of gravity, when the air conditioner is performing air cooling, all the condensate on the pipes connecting the liquid distributor 400 and the heat exchanger 200 will be collected in the water collection tray 500 for collection and treatment, making the use of the air conditioner safer, and thus making the data center equipped with this air conditioner safer, less prone to water flooding, and reducing safety hazards.

[0039] It should be noted that the air inlet 1910 and air outlet 1920 of the air conditioner are... Figure 3 The two sides in the direction of x'. Specifically, the air inlet 1910 is on the right side from x to x', and the air outlet 1920 is on the left side from x' to x.

[0040] Please see Figure 2 In one embodiment, the number of fans 300 is one. Of course, in other embodiments, the number of fans 300 may be two, three, or four, etc., and there is no special limitation on this. It can be increased or decreased according to the project design requirements.

[0041] In one specific embodiment, the heat exchanger 200 is a tube-fin heat exchanger 200, which is a high-efficiency heat exchange device composed of sealed pipes and metal fins stacked together.

[0042] The following is a detailed description of the structure of an air conditioner. Please refer to [link / reference]. Figure 4 , Figure 4 Shown Figure 3 The enlarged view at point A is shown. In some embodiments, the dispenser 400 is provided with a plurality of spaced-apart dispensing tube interfaces 410; see also... Figure 2 and Figure 3 Specifically, the airflow direction of the air conditioner is from the air inlet 1910 to the air outlet 1920. That is... Figure 3 The direction from x to x' is indicated by the heat exchanger 200. Multiple spaced heat exchange tubes 210 are constructed on the side of the heat exchanger 200 away from the air inlet 1910. Each liquid distribution pipe interface 410 is connected to one of the heat exchange tubes 210. By arranging multiple spaced heat exchange tubes 210 on the side away from the air inlet 1910, and ensuring that each liquid distribution pipe interface 410 is connected to one of the heat exchange tubes 210, the refrigerant in the air conditioner can enter the heat exchanger 200 for heat exchange. Furthermore, since the heat exchange tubes 210 are located on the side away from the air inlet 1910, the connection between the liquid distribution pipe interface 410 on the liquid distributor 400 located on the same side as the air inlet 1910 and the heat exchange tubes 210 is convenient and the layout is reasonable.

[0043] Please see Figure 4 In some embodiments, multiple dispensing tube interfaces 410 are evenly spaced along the circumference of the dispenser 400. By arranging multiple dispensing tube interfaces 410 at intervals along the circumference of the dispenser 400, the dispenser 400 is made easier to manufacture.

[0044] In some embodiments, the air conditioner also includes multiple capillary tubes (not shown in the figure), each capillary tube being connected between a liquid distribution port 410 and a heat exchange tube 210; the outer contour of the orthographic projection of the water collection tray 500 along the direction of gravity is located outside the outer contour of the orthographic projection of the capillary tube along the direction of gravity. By setting multiple capillary tubes and making the outer contour of the orthographic projection of the water collection tray 500 along the direction of gravity located outside the outer contour of the orthographic projection of the capillary tube along the direction of gravity, the condensate formed on the capillary tube wall during the use of the air conditioner can drip and be collected into the water collection tray 500 under the action of gravity, thereby making the use of the air conditioner safer, and thus making the data center equipped with the air conditioner safer, less prone to water flooding, and reducing safety hazards.

[0045] It should be noted that in traditional air conditioner layouts, the capillary tube is placed close to the air inlet 1910 of the heat exchanger 200, which significantly affects the system's air intake and reduces air conditioning performance. Furthermore, due to the small size of the portion covered by the bottom drip tray 500, condensation on the capillary tube is highly likely to drip onto the base plate 100, causing corrosion. By optimizing the structure of the heat exchanger 200—specifically, placing the distributor 400, heat exchange tube 210, and capillary tube on the side of the heat exchanger 200 away from the air outlet 1920, and ensuring that the outer contours of their orthogonal projections along the direction of gravity are all within the outer contours of the drip tray 500 along the direction of gravity—the components that may generate condensate during use are completely enclosed within the drip tray 500. This effectively utilizes the drip tray 500's water-collecting area and avoids safety hazards caused by condensate leakage. Simultaneously, the air intake area is greatly increased, enlarging the heat exchange area of ​​the heat exchanger 200 and improving cooling capacity.

[0046] Please see Figure 3 In some embodiments, the outer contour of the orthographic projection of the drip tray 500 along the direction of gravity is located outside the outer contour of the orthographic projection of the heat exchanger 200 along the direction of gravity. By placing the outer contour of the orthographic projection of the drip tray 500 along the direction of gravity outside the outer contour of the orthographic projection of the heat exchanger 200 along the direction of gravity, condensate on the heat exchanger 200 can also drip down under gravity and be collected in the drip tray 500, making the use of the air conditioner safer.

[0047] Please see Figure 3 In some embodiments, the heat exchanger 200 is arranged diagonally along the drip tray 500. Because the heat exchanger 200 is relatively large, arranging it diagonally along the drip tray 500 results in a smaller drip tray 500 and a smaller footprint compared to arranging it along the length or width of the drip tray 500. This ultimately leads to a smaller overall footprint and higher space utilization for the air conditioner.

[0048] In some embodiments, the side of the fan 300 away from the heat exchanger 200 is also provided with an openable and closable opening; the air conditioner also includes an openable and closable door (not shown in the figure), which is installed at the openable and closable opening and is used to open or close the openable and closable opening. By placing the openable and closable door at the openable and closable opening, it is very convenient to open and operate when the internal components of the air conditioner need to be inspected or replaced.

[0049] Please see Figure 2 and Figure 3 In some embodiments, the air conditioner also includes an electronic expansion valve 600, which is installed between the fan 300 and the distributor 400. By placing the electronic expansion valve 600 between the fan 300 and the distributor 400, i.e., within the air cavity at the front of the air conditioner, the design space at the air inlet 1910 of the air conditioner is simplified. Furthermore, due to the presence of the door, the electronic expansion valve 600 can be replaced promptly when the door is opened, fulfilling the requirement of maintenance clearance simply by opening the door.

[0050] Please see Figure 1 and combined Figure 2 In some embodiments, the air conditioner further includes a compressor 1100, an exhaust pipe 1200, an oil separator 800, a one-way valve 900, an indoor unit outlet pipe 1700, an outdoor unit condenser, an indoor unit return pipe 1800, a dryer filter 1600, and a system connection pipe 1500 connected in sequence. The side of the system connection pipe 1500 away from the dryer filter 1600 is connected to an electronic expansion valve 600. The air conditioner also includes a return gas manifold 1400 connected to the heat exchange pipe 210. A return gas pipe 1300 is connected to the side of the return gas manifold 1400 away from the heat exchange pipe 210, and the side of the return gas pipe 1300 away from the return gas manifold 1400 is connected to the compressor 1100. This ensures that the airflow path inside the entire air conditioner is circulated and connected.

[0051] After the refrigerant in the air conditioner is compressed in the compressor 1100, it enters the oil separator 800 through the discharge pipe 1200. The oil separator 800 separates relatively pure refrigerant gas, which passes through the one-way valve 900 and enters the outdoor unit condenser through the indoor unit outlet pipe 1700, releasing heat and cooling into a liquid. Then, it returns to the air conditioner cabinet through the indoor unit return pipe 1800. After being purified in the dryer filter 1600, it enters the electronic expansion valve 600 through the system connection pipe 1500. After being throttled and depressurized in the electronic expansion valve 600, it is delivered to the distributor 400. From there, the capillary tubes connected to the distributor spray the refrigerant into the heat exchanger 200, where it evaporates and absorbs heat to become a gas. After converging through the return manifold 1400, it is drawn back into the compressor 1100 through the return pipe 1300, and the cycle repeats.

[0052] Please see Figure 1In some embodiments, the air conditioner also includes a sight glass 1000, which is mounted on the system connection pipe 1500. The refrigerant status is observed through the sight glass 1000, making its use relatively safe.

[0053] Please see Figure 1 and Figure 3 In some embodiments, the air conditioner also includes a wet film 700, which is installed on the side of the heat exchanger 200 away from the distributor 400; the wet film 700 is detachably connected to the heat exchanger 200. By installing the wet film 700 on the side of the heat exchanger 200 away from the distributor 400, that is, on the side of the air inlet 1910, and by detachably connecting the wet film 700 to the heat exchanger 200, the distributor 400 and the pipes connected to the distributor 400 are less likely to interfere with the movement of the wet film 700 when the wet film 700 needs to be replaced during later use of the air conditioner, thus facilitating the movement of the wet film 700.

[0054] During the use of the air conditioner, the cooling capacity generated by the heat exchanger 200 and the moisture provided by the wet film 700 are drawn away by the fan 300 and sent into the room for air conditioning; the condensate generated by the heat exchanger 200, the distributor 400, the wet film 700 and the capillary tube will flow to the drip tray 500.

[0055] This application also provides a heat dissipation system comprising at least one air conditioner as described in any of the above embodiments, capable of achieving at least one of the above-described technical effects. In one embodiment, the heat dissipation system comprises an air conditioner as described in any of the above embodiments, thereby allowing the wet film 700 to be drawn out from the upper side of the air conditioner. Figure 1 and Figure 2 (from z' to z) and the left and right sides ( Figure 1-Figure 3 The yy' direction (referring to the left and right directions) can be inspected or replaced on either side. In another specific embodiment, the heat dissipation system includes two or more air conditioners connected sequentially to each other. In this case, the wet film 700 can be pulled out from above the air conditioner for inspection and replacement, which is relatively simple and convenient.

[0056] The air conditioning and heat dissipation system provided in this application embodiment has a simple structure, is easy to manufacture, economical and practical, safe and reliable, highly versatile and interchangeable, and can form a standardized production system layout structure.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
