Description

Technical Field

[0001] This application relates to the technical field of air conditioning, and more specifically, to an evaporator structure and air conditioning equipment. Background Technology

[0002] Thin-wall or back-panel air conditioners have a thinner profile, thus taking up less space. They are suitable for scenarios where server capacity and server room space are limited. Because they can be placed close to the server for efficient heat dissipation, they are widely used in the data center industry.

[0003] In the process of realizing this invention, the inventors discovered that the prior art has at least the following problems: Rear-panel air conditioners adopt a "rear air intake, front air exhaust" layout. Because of their compact size, the fan and evaporator are often more closely spaced in their structural layout. Figure 1 As shown, during operation, the evaporator converts the refrigerant from a liquid to a gaseous state. Due to the temperature difference between the inlet and outlet air, condensation will form on the components of the evaporator assembly as the temperature changes and the temperature drops below the dew point. When the fan is close to the evaporator, the fan's operation can easily carry the condensation produced by the evaporator out of the air conditioning equipment through the air duct, creating a water blowing phenomenon. Utility Model Content

[0004] This application provides an evaporator structure and an air conditioning device. The evaporator structure can effectively reduce the occurrence of water blowing, thereby improving the safety and comfort of the air conditioning device during use.

[0005] In a first aspect, this application provides an evaporator structure, which adopts the following technical solution:

[0006] An evaporator structure, comprising:

[0007] An evaporator includes a mounting frame, fins, and a first tube group and a second tube group disposed on both sides of the mounting frame. The fins, the first tube group, and the second tube group are all disposed on the mounting frame. The mounting frame has a first end plate and a second end plate on opposite sides in the horizontal direction, and the fins are disposed between the first end plate and the second end plate.

[0008] A water-blocking assembly includes a first protective plate and a second protective plate. The first protective plate and the first end plate form a first water-blocking shell, and the first pipe assembly is disposed inside the first water-blocking shell. The second protective plate and the second end plate form a second water-blocking shell, and the second pipe assembly is disposed inside the second water-blocking shell.

[0009] The first water receiving tray is used to collect the condensate from the fins, the first water-blocking shell, and the second water-blocking shell.

[0010] In some technical solutions, the inner walls of the first protective plate and the second protective plate are both provided with a heat insulation layer, which is used to block the temperature transfer between the inner and outer spaces of the first protective plate and the second protective plate.

[0011] In some technical solutions, the first water receiving tray is provided with a first drain outlet, and a first drain pipe is connected to the first drain outlet.

[0012] In some technical solutions, the bottom surface of the first water receiving tray has a high end and a low end, the vertical distance between the high end and the ground is greater than the vertical distance between the low end and the ground, and the first drain pipe is located at the low end.

[0013] In some technical solutions, the surface of the fins is coated with a hydrophilic coating.

[0014] In some technical solutions, the evaporator structure further includes a second water receiving tray. The fins have multiple fins, which are arranged vertically as a first fin group and a second fin group. The second water receiving tray is disposed between the first fin group and the second fin group and is fixed to the mounting bracket. The length and width of the second water receiving tray are both greater than the length and width of the first fin group. The second water receiving tray is located opposite the first fin group to collect condensate.

[0015] In some technical solutions, the first water receiving tray is disposed on the first water-blocking shell, the second water-blocking shell, and the second fin group, and the orthographic projection of the first water-blocking shell, the second water-blocking shell, and the second fin group completely coincides with the orthographic projection of the first water receiving tray.

[0016] In some technical solutions, the second water receiving tray is provided with a second drain hole, and a second drain pipe is connected to the second drain hole. The two ends of the second drain pipe are respectively connected to the first water receiving tray and the second water receiving tray.

[0017] In some technical solutions, both ends of the first water-blocking shell and the second water-blocking shell are configured as openings.

[0018] Secondly, this application provides an air conditioning device, which adopts the following technical solution:

[0019] An air conditioning device includes the above-described evaporator structure and fan assembly, wherein the fan assembly is disposed on one side of the evaporator structure.

[0020] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0021] When condensation occurs in the first end plate, second end plate, first pipe assembly, and second pipe assembly due to temperature changes, the first and second water-blocking shells can immediately confine the condensation within their respective enclosed shells. The condensation can only flow downwards along the shell walls into the first water-collecting tray under the influence of gravity, thus completely eliminating horizontal splashing and wind-blown water. Furthermore, the first and second water-blocking shells, together with the first water-collecting tray, form two condensation flow zones, upgrading the existing two-dimensional planar drainage of the evaporator with the first water-collecting tray to a shell-based three-dimensional flow guide and zoned collection effect. This achieves condensation collection, preventing condensation from being carried outside the air conditioning unit by the fan assembly, reducing the occurrence of water blowing, and thus improving the safety and comfort of the air conditioning equipment during use.

[0031] This application provides an evaporator structure and an air conditioning device. The evaporator structure can effectively reduce the occurrence of water blowing, thereby improving the safety and comfort of the air conditioning device during use.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application. Furthermore, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present application.

[0033] Thin-wall or rear-panel air conditioners, due to their compact size, often have the fan and evaporator positioned closer together in their structural layout. During operation, the evaporator converts the refrigerant from a liquid to a gaseous state. At this time, condensation forms on the components of the evaporator assembly due to temperature changes and when the temperature drops below the dew point. When the fan and evaporator are close together, the fan's operation can easily carry the condensate produced by the evaporator out of the air conditioning unit, resulting in a water-blowing phenomenon. To solve the above technical problem, this application discloses an evaporator structure and air conditioning equipment. Please refer to... Figures 2 to 5 , Figure 2 This is an overall schematic diagram of an evaporator structure disclosed in an embodiment of this application; Figure 3 for Figure 2 Enlarged view of the structure at point A in the middle, to highlight the fit between the first pipe assembly 12 and the first water-blocking shell; Figure 4 for Figure 2 Enlarged view of the structure at point B in the middle to highlight the fit between the second pipe assembly 13 and the second water-blocking shell; Figure 5 for Figure 2 The enlarged view of the structure at point C highlights the fit between the second water receiving tray 6 and the fins.

[0034] Please see Figure 2 This is one embodiment of the evaporator structure of the present application. The evaporator structure includes an evaporator 1, a water-blocking assembly, and a first water receiving tray 4. During operation, the evaporator 1 converts the refrigerant from a liquid state to a gaseous state to achieve cooling. During the process of the refrigerant converting from a liquid state to a gaseous state, the condensate generated by the temperature change of each component of the evaporator 1 is blocked by the water-blocking assembly, thereby preventing it from being carried out of the air conditioner by the fan, thus achieving the effect of preventing water from being carried out. The first water receiving tray 4 is used to collect the condensate after the evaporation of each component of the evaporator 1.

[0035] The evaporator 1 includes a mounting bracket 11, fins (not shown in the figure), and a first tube group 12 and a second tube group 13 disposed on both sides of the mounting bracket 11. The fins, the first tube group 12, and the second tube group 13 are all disposed on the mounting bracket 11. The mounting bracket 11 has a first end plate 111 and a second end plate 112 on opposite sides in the horizontal direction. It should be noted that the area between the first end plate 111 and the second end plate 112 is the fin mounting area. The evaporator 1 has refrigerant pipes for containing refrigerant. The first end plate 111 and the second end plate 112 have multiple through holes. The two ends of the refrigerant pipes pass through the through holes to exit the fin area and then pass through the through holes to enter the fin area. Therefore, multiple curved U-shaped pipes are formed on the side of the first end plate 111 away from the fin area. These multiple curved U-shaped pipes form a U-shaped tube group, namely the first tube group 12. The first end plate 111 has an inlet manifold and an outlet manifold on the side away from the fin area, respectively connecting the two ends of the refrigerant pipe. The inlet manifold and the outlet manifold form a manifold assembly, namely the second manifold assembly 13. Both the first manifold assembly 12 and the second manifold assembly 13 are exposed to the internal space of the air conditioning equipment. When the refrigerant changes from a liquid state to a gaseous state, condensation will be generated on the surface of the pipes of the first manifold assembly 12 and the second manifold assembly 13 due to temperature changes and when the temperature is below the dew point temperature.

[0036] Please see Figure 3 and Figure 4 The anti-blowing component includes a first guard plate 2 and a second guard plate 3. The first guard plate 2 and the first end plate 111 enclose a first water-blocking shell, and a first pipe group 12 is disposed inside the first water-blocking shell. The second guard plate 3 and the second end plate 112 enclose a second water-blocking shell, and a second pipe group 13 is disposed inside the second water-blocking shell. The first water receiving tray 4 is used to receive condensate from the fins, the first water-blocking shell, and the second water-blocking shell.

[0037] Understandably, when condensation occurs in the first end plate 111, the second end plate 112, the first pipe assembly 12, and the second pipe assembly 13 due to temperature changes, the first and second water-blocking shells can confine the condensation generated by these components within their respective enclosed water-blocking shells at the moment of generation. The condensation can only flow downwards along the wall of the water-blocking shell into the first water-receiving tray 4 under the action of gravity, thereby completely eliminating horizontal splashing and wind-blown water. Secondly, the first and second water-blocking shells, together with the first water-receiving tray 4, form two condensation flow areas, upgrading the two-dimensional planar drainage of the evaporator 1 and the first water-receiving tray 4 in the prior art to a shell-based three-dimensional flow guidance and zoned collection effect, thereby achieving condensation collection and preventing condensation from being carried out of the air conditioning equipment by the fan assembly, reducing the occurrence of water blowing, and thus improving the safety and comfort of the air conditioning equipment during use.

[0038] In this embodiment, both ends of the first and second water-blocking shells are configured with openings. Specifically, the first protective plate 2 and the first end plate 111 enclose a first water-blocking shell with a sealed periphery, and the second protective plate 3 and the second end plate 112 enclose a second water-blocking shell with a sealed periphery. The first and second water-blocking shells are axially connected and have sealed shell walls. On the one hand, this prevents the condensate from the first end plate 111, the second end plate 112, the first pipe group 12, and the second pipe group 13 from escaping laterally due to surface tension. Instead, the condensate can only flow out from the lower openings of the first and second water-blocking shells into the first water receiving tray 4 under the action of gravity. On the other hand, the openings ensure that the interior of the first and second water-blocking shells remains part of the main air duct, achieving the effect of allowing air to pass through but not water. The longitudinal airflow can avoid sacrificing heat exchange efficiency for water blocking.

[0039] Furthermore, both the inner walls of the first protective plate 2 and the second protective plate 3 are provided with a thermal insulation layer 5. The thermal insulation layer 5 is used to block the temperature transfer between the inner and outer spaces of the first protective plate 2 and the second protective plate 3. The thermal insulation layer 5 is preferably thermal insulation cotton. It can be understood that the thermal insulation layer 5 can completely insulate the "low temperature zone" inside the first and second water-blocking shells from the "high temperature and high humidity zone" outside the first and second water-blocking shells, so that the inner surface temperature of the first protective plate 2 and the second protective plate 3 is always higher than the dew point of the surrounding air, thereby eliminating the generation of additional condensation in the first and second protective plates 2 and 3, and further reducing the possibility of water blowing.

[0040] Please see Figure 2 In this embodiment, the two ends of the first water receiving tray 4 are fixedly connected to the first protective plate 2 and the second protective plate 3, respectively, and the first water receiving tray 4 is located in the area below the fins, the first water-blocking shell, and the second water-blocking shell. The first water receiving tray 4 is provided with a first drain outlet, and a first drain pipe 41 is connected to the first drain outlet. The condensate generated during heat exchange drips into the first water receiving tray 4, and then the water in the first water receiving tray 4 is discharged through the first drain outlet and the first drain pipe 41. The first drain pipe 41 facilitates the drainage of the water in the first water receiving tray 4 into a specific external pipe.

[0041] Furthermore, the bottom surface of the first water receiving tray 4 has a high end 42 and a low end 43. The vertical distance between the high end 42 and the ground is greater than the vertical distance between the low end 43 and the ground. The first drain pipe 41 is located at the low end 43. It is understood that a slope can be formed between the high end 42 and the low end 43. Due to the relatively long length of the first water receiving tray 4, the slope and the arrangement of the drain pipe at the low end 43 form a gravity-driven, rapid drainage system. When condensate is present in the first water receiving tray 4, the condensate can flow along the slope to the first drain outlet and be discharged through the first drain pipe 41, ensuring that all condensate is discharged from the first water receiving tray 4, preventing stagnant water and water accumulation. Secondly, the shear stress generated by the water flow along the slope can continuously push dust particles towards the first drain outlet, reducing the formation of biofilm and decreasing the frequency of manual cleaning.

[0042] The left side of the evaporator 1 is equipped with a first end plate 111 and a first protective plate 2 to shield the first pipe assembly 12. At the same time, the inner wall of the first protective plate 2 is wrapped with insulation cotton. The right side of the evaporator 1 is equipped with a second end plate 112 and a second protective plate 3 to shield the second pipe assembly 13. At the same time, the inner wall of the second protective plate 3 is wrapped with insulation cotton. When condensate is generated by the first end plate 111, the second end plate 112, the first pipe assembly 12, and the second pipe assembly 13, the condensate can be contained in a closed area. At the same time, this area is connected to the first water receiving tray 4 to form two condensate flow areas on the left and right, and finally drained normally through the first drain pipe 41.

[0043] Fins are used to increase the contact area with air and improve heat exchange efficiency. In the embodiments of this application, there are multiple fins, and the surface of each fin is coated with a hydrophilic coating, preferably hydrophilic aluminum foil. It should be noted that the hydrophilic coating can reduce the contact angle, increase the capillary migration speed, and inhibit the secondary aggregation of condensation. The contact angle of ordinary aluminum foil is about 80°–90°, and the water on the surface of ordinary aluminum foil is in bead form; the hydrophilic coating can reduce the contact angle to less than or equal to 10°, and the condensate can instantly spread into a uniform water film on the surface of the hydrophilic coating. Because the thickness of the water film is less than the critical rupture thickness, it will not bridge or merge into large water droplets between the fins. When condensate forms on the fin, the condensate forms a water film on the fin surface. Under the action of gravity, the water film on the fin surface migrates downward along the fin, thereby eliminating the source of "flying droplets" formed by high-speed airflow shearing, fundamentally cutting off the water source for blowing.

[0044] When the fin area is too long, the time required for condensate to flow to the first drip tray 4 increases accordingly. To prevent the condensate from being easily blown away by the high-speed airflow along the way, the evaporator structure is also equipped with a second drip tray 6. The second drip tray 6 is horizontally positioned in the middle of the mounting bracket 11, and its two ends are fixedly connected to the first end plate 111 and the second end plate 112, respectively. It can be understood that the second drip tray 6 is used to collect a portion of the condensate from the fins, while the first drip tray 4 is used to collect the remaining condensate from the fins, as well as the condensate from the first pipe group 12 and the second pipe group 13. It can be understood that the first drip tray 4 and the second drip tray 6, working together, form two independent and controllable drainage units, effectively diverting and collecting condensate, ensuring smooth discharge, and preventing fin-blowing.

[0045] Specifically, in this embodiment, multiple fins are vertically configured as a first fin group and a second fin group. The first fin group is located above the second fin group. A second condensate tray 6 is positioned between the first and second fin groups and fixed to the mounting bracket 11. The length and width of the second condensate tray 6 are greater than those of the first fin group. The second condensate tray 6 is positioned opposite the first fin group to collect condensate, ensuring that the condensate from the first fin group falls within the range of the second condensate tray 6. Notably, the second condensate tray 6 acts as a reinforcing beam, halving the fin span and eliminating depressions in the middle of the fins, preventing condensation from forming large droplets. Furthermore, the second condensate tray 6 divides the total condensation volume of the fins in half, bearing half the load, thus halving the static water accumulation height within the second condensate tray 6, keeping it below the safety threshold of the fan assembly inlet.

[0046] The first water receiving tray 4 is positioned on the first water-retaining shell, the second water-retaining shell, and the second fin assembly, with the orthographic projections of the first water-retaining shell, the second water-retaining shell, and the second fin assembly completely coinciding with the orthographic projection of the first water receiving tray 4. Water droplets falling from any position on the first water-retaining shell, the second water-retaining shell, and the second fin assembly can be caught by the first water receiving tray 4 upon vertical fall, with minimal horizontal drift, achieving zero lateral splashing and ensuring that the condensate from the first water-retaining shell, the second water-retaining shell, and the second fin assembly falls within the range of the first water receiving tray 4.

[0047] To facilitate the drainage of condensate in the second drip tray 6, a second drain hole is provided in the second drip tray 6. A second drain pipe 61 is connected to the second drain hole, and the two ends of the second drain pipe 61 are connected to the first drip tray 4 and the second drip tray 6, respectively. To avoid drainage delay when the first drip tray 4 is too long, two sets of second drain pipes 61 and second drain holes are provided, and the second drain pipes 61 and the second drain holes are set in a one-to-one correspondence. The two second drain pipes 61 are respectively set at the two ends of the second drip tray 6.

[0048] Understandably, the two independent second drain pipes 61 form a dual channel. Even with partial bends in either second drain pipe 61, 50% of the diameter is still retained. The two independent second drain pipes 61 can jointly guide the water in the second water receiving pan 6 to the first water receiving pan 4, and then discharge it through the first drain pipe 41 of the first water receiving pan 4. This means that the entire unit only needs to retain one first drain pipe 41 of the first water receiving pan 4 for external use. The second water receiving pan 6 does not need to be threaded through sheet metal or connected to external joints, reducing the number of outlets, thereby reducing potential leakage points and improving the reliability of the air conditioning equipment.

[0049] When condensation occurs in the first fin group, the condensate is adsorbed onto the fins due to the hydrophilic coating. At the same time, it resists the suction force of the airflow generated by the fan assembly. Under the action of gravity, the condensate forms a water film and flows down along the fins, then enters the second water receiving tray 6. It is then connected to the first water receiving tray 4 through the second drain pipe 61, and finally drained normally through the first drain pipe 41. When condensation occurs in the second fin group, the condensate directly enters the first water receiving tray 4. Since the first water receiving tray 4 is relatively long, its bottom surface is designed with a certain slope, and the first drain pipe 41 is set at the lowest point to ensure that there is no stagnant water in the first water receiving tray 4.

[0050] In other embodiments of the above embodiments, the end of the second drain pipe 61 away from the second water receiving pan 6 is connected to a specific external pipe, and the water in the second water receiving pan 6 can be directly discharged into the external pipe.

[0051] This application also discloses an air conditioning device, which includes the aforementioned evaporator structure and a fan assembly, with the fan assembly disposed on one side of the evaporator structure. Because the air conditioning device employs all the technical solutions of all embodiments of the aforementioned evaporator structure, even with its compact size and close proximity to the evaporator structure, the occurrence of water blowing can be effectively reduced thanks to the action of the first water-blocking shell, the second water-blocking shell, the first water-receiving tray 4, and the second water-receiving tray 6. This prevents condensate from being carried out through the air duct during use, thereby improving the safety and comfort of the air conditioning device. Therefore, this air conditioning device possesses at least all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be elaborated upon further here.
