Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a surface cooler structure, a V-shaped heat exchange device and a computer room air conditioner. Background Art

[0002] Nowadays, the domestic economy is developing rapidly, and the demand for cooling capacity in computer rooms, shopping malls, airports, subway stations and other places is increasing. In order to reduce operating power consumption and achieve the dual carbon goals, computer room air-conditioning products are developing in the direction of energy saving and large-scale cooling.

[0003] V-shaped computer room air conditioners are becoming more and more popular in the market. Its V-shaped design increases the contact area between the air and the heat exchanger, thereby improving the heat exchange efficiency and making the cooling or heating effect better. Compared with other models, its advantage is that it improves the heat exchange efficiency; due to the improvement of heat exchange efficiency, the running time of the compressor can be reduced, thereby reducing energy consumption and saving operating costs. At the same time, the V-shaped design can be arranged more compactly, saving installation space in the computer room, and is especially suitable for environments with limited space. In addition, the V-shaped design can evenly distribute the airflow, reduce airflow turbulence, and thus reduce noise during operation. In summary, the application of the V-shaped design in computer room air conditioners can significantly improve the performance and reliability of the air conditioning system, while reducing operating costs and maintenance costs.

[0004] However, this structure also has certain defects. When the unit needs to supply air downward, the fan is located at the bottom of the unit. In order to keep the opening angle of the two V-shaped surface coolers always facing the fan, the two V-shaped surface coolers are in an inverted V state. In this state, the center of gravity of the condensed water in the two V-shaped surface coolers is vertically downward. When there is condensed water, the water can be adsorbed on the fins through the hydrophilicity of the fins and drained into the water receiving tray along the direction of the fins. However, when the air humidity is high, the surface cooler is too long or other reasons cause more condensed water to be generated during the operation of the unit, the condensed water will converge when flowing downward along the fins. At this time, the amount of water is large, and the adsorption force of the fins is not enough to make it flow downward in the direction of the fins. The condensed water may drip directly into the air cavity under the action of the water droplets' own gravity, or float into the air cavity with the incoming air under the suction of the fan. This phenomenon has been confirmed in the laboratory.

[0005] Water ingress into the air cavity of the unit not only affects the service life of the fan, but also corrodes other parts inside the fan, such as electric heating parts. In addition, it will increase the humidity in the air supply duct, greatly affecting the humidity of the machine room space that needs to be cooled, and then corrode the machines and other parts in the machine room, which is extremely harmful.

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a surface cooler structure, a V-shaped heat exchange device and a computer room air conditioner, which are intended to prevent the problem that condensed water gathers into large water droplets and then floats into the fan.

[0046] like Figures 1 to 12 As shown, an embodiment of the present invention provides a cooler structure, including a cooler body 1, a first water receiving assembly 2, a second water receiving assembly 3 and a first drainage member 5. The cooler body 1 includes a plurality of cooler units 11 spliced ​​and connected up and down, and the number of splicing of the cooler units 11 can be selected according to actual needs. The first water receiving assembly 2 is arranged at the splicing of at least one of the cooler units 11 of the cooler body 1, that is, the first water receiving assembly 2 can be arranged at all splicings, or the first water receiving assembly 2 can be arranged at a part of all splicings. The second water receiving assembly 3 is arranged at the bottom of the cooler body 1, that is, the second water receiving assembly 3 is located at the bottom of all the first water receiving assemblies 2. The first drainage member 5 is connected between the first water receiving assembly 2 and the second water receiving assembly 3. The first drainage member 5 can be one or more diversion pipes, which are made of corrosion-resistant plastic or metal materials. The water of the first water receiving assembly 2 is drained to the second water receiving assembly 3 through the first drainage member 5.

[0047] The present invention sets a first water receiving component 2 at the joint of the surface cooler unit 11. The first water receiving component 2 can intercept the condensed water generated by the surface cooler unit 11 in advance to prevent the water droplets from increasing. The intercepted condensed water gathers in the first water receiving component 2, and then is drained to the second water receiving component 3 by the first drainage member 5, thereby preventing the condensed water from gathering into large water droplets and then floating into the fan, thereby effectively protecting the internal components of the unit and keeping the humidity in the air duct unchanged.

[0048] like Figure 4 As shown, in the present embodiment, the cooler body 1 includes two cooler units 11 spliced ​​up and down, the first water receiving assembly 2 is arranged at the splicing of the two cooler units 11, the second water receiving assembly 3 is arranged at the bottom of the cooler unit 11 located below, the first drainage member 5 is a hose, the first drainage member 5 is arranged along the height direction of the cooler unit 11, the path design of the first drainage member 5 should divert water to the second water receiving assembly 3 with the shortest distance to ensure the high efficiency of the water flow, the upper end of the first drainage member 5 is connected to the first water receiving assembly 2, and the lower end of the first drainage member 5 is connected to the second water receiving assembly 3.

[0049] In one embodiment, if Figures 4 to 8As shown, the first water receiving assembly 2 includes a first water receiving tray 21, and the first water receiving tray 21 is provided with a first water collecting trough 211. The opening of the first water collecting trough 211 faces upward, and a first drainage hole 2111 is provided at the bottom of the first water collecting trough 211. The first drainage hole 2111 is connected to the first drainage member 5, and the water in the first water collecting trough 211 flows to the first drainage member 5 through the first drainage hole 2111.

[0050] The first water receiving tray 21 can be made of highly corrosion-resistant materials, such as stainless steel or corrosion-resistant alloys, to ensure its durability for long-term use in humid environments. The opening of the first water collecting tank 211 faces upward, so that the condensed water flowing down from the surface of the surface cooler unit 11 can naturally enter the water collecting tank. The width and length of the first water collecting tank 211 need to be adapted to the width and length of the surface cooler unit 11 to ensure that the water flow can be effectively accommodated even when the amount of condensed water generated is large. The first drain hole 2111 can be one or more, and the design position of the first drain hole 2111 can be set according to actual conditions so that the water collected in the first water collecting tank 211 can be quickly discharged to prevent overflow due to excessive water level.

[0051] The design of the first water receiving assembly 2 ensures that condensed water can be quickly and effectively collected and discharged from the surface of the surface cooler unit 11, thereby reducing possible equipment damage caused by water accumulation.

[0052] like Fig. 9 As shown, the surface cooler unit 11 includes a fin 111, two side plates 113 and an upper guard plate 112. The upper guard plate 112 is arranged on the upper side of the fin 111 to provide protection for the fin 111 and prevent external physical damage or pollution. The two side plates 113 are arranged on the front and rear sides of the fin 111 respectively to provide structural support and protection. The upper guard plate 112 and the two side plates 113 are connected and fixed with screws, and the two ends of the first water receiving tray 21 are connected and fixed with the lower ends of the two side plates 113 with screws. During installation, the fin 111 is embedded in the first water collecting tank 211 of the first water receiving tray 21, so that the side of the first water collecting tank 211 can cover the fin 111, so as to facilitate the water on the fin 111 to enter the first water collecting tank 211.

[0053] In one embodiment, a first guide plate 22 is provided on one side of the first water receiving tray 21, extending away from the bottom of the first water collecting tank 211. The first guide plate 22 and the first water receiving tray 21 can be of separate design or of integrated design.

[0054] like Figures 10 to 12 As shown, the first guide plate 22 is disposed facing the fin 111. In actual application, the entire surface of the surface cooler unit 11 is air intake, and the air sucked in by the fan ( Fig.11The middle arrow indicates the flow direction of the wind sucked in by the fan at the position of the first guide plate 22), which can easily blow the condensed water in the first water receiving tray 21 into the fan cavity 9. Since the first guide plate 22 is provided, the condensed water blown by the wind is guided to the fins 111 through the first guide plate 22 and then falls back into the first water receiving tray 21, thereby preventing the wind from blowing the water in the first water receiving tray 21 into the fan cavity 9.

[0055] In one embodiment, the top of the first guide plate 22 is provided with a folded edge portion bent toward the fin 111. The design of the folded edge portion ensures that when the fan is running, the first guide plate 22 can effectively change the airflow path, thereby being more conducive to redirecting the condensed water to the surface of the fin 111.

[0056] In one embodiment, the condenser body 1 further includes a connector for connecting two upper and lower adjacent condenser units 11 , and the first water receiving pan 21 is arranged along the length direction of the condenser unit 11 , and the first water receiving pan 21 is located on the inner side of the connector.

[0057] like Figure 1-Figure 2 , Fig. 9 As shown, the connecting piece is a plate-like structure with screw holes 121 thereon. There are two connecting pieces, one in front and one in back, respectively located at the front and rear sides of the two upper and lower adjacent cooler units 11. During installation, one of the connecting pieces is fixedly connected to the front side plates 113 of the two upper and lower adjacent cooler units 11 through the screw holes 121 with screws, and the other connecting piece is fixedly connected to the rear side plates 113 of the two upper and lower adjacent cooler units 11 through the screw holes 121 with screws. With this design, while ensuring the stability of the connection between the two upper and lower adjacent cooler units, the first water receiving tray 21 can be enclosed between the two connecting pieces, making the overall structure more compact and convenient for disassembly and assembly.

[0058] In one embodiment, the second water receiving assembly 3 includes a second water receiving tray 31 . The second water receiving tray 31 is provided with a second water collecting tank 311 . The opening of the second water collecting tank 311 faces upward. The second water collecting tank 311 is provided with a second drainage member 34 .

[0059] The second water receiving pan 31 can be made of highly corrosion-resistant materials, such as stainless steel or corrosion-resistant alloys, to ensure its durability for long-term use in humid environments. The opening of the second water collecting tank 311 faces upward, so that the condensed water flowing down from the surface of the surface cooler unit 11 can naturally enter the water collecting tank. The width and length of the second water collecting tank 311 need to be adapted to the width and length of the surface cooler unit 11 to ensure that the water flow can be effectively accommodated even when the amount of condensed water generated is large. The second drainage member 34 can be one or more diversion pipes, which can be made of corrosion-resistant plastic or metal materials. The second drainage member 34 is connected to the sewer system or a designated drainage area. The design of the second drainage member 34 ensures that the water in the water collecting tank can be quickly discharged to avoid water accumulation.

[0060] like Figure 3 As shown, in this embodiment, two cooler bodies 1 share a second water receiving tray 31, and the second water receiving tray 31 is in a half-mouth shape. The areas where the two vertical sides of the second water receiving tray 31 are opposite to each other can correspond to the bottoms of the two cooler bodies 1. Such a design can reduce the manufacturing cost and make the structure more compact. Of course, in some other embodiments, the second water receiving trays 31 at the bottom of multiple cooler bodies 1 are designed as independent types.

[0061] In one embodiment, the second water receiving assembly 3 further includes a support member 32, which is disposed in the second water collecting tank 311. The support member 32 is in a long block structure, and the support member 32 contacts the bottom of the cooler body 1. The side of the support member 32 that contacts the bottom of the cooler body 1 is an inclined surface, so as to adapt to the installation angle of the cooler body 1. The support member 32 is fixed in the second water collecting tank 311 by screws, and the second water collecting tank 311 is penetrated by a second drainage hole 321, which is connected with the first drainage member 5 and the second drainage member 34. When working, the water flows from the first water receiving pan 21 into the first drainage member 5, passes through the second drainage hole 321, reaches the second water receiving pan 31, and then flows out from the second drainage member 34.

[0062] In one embodiment, a second guide plate 33 is provided on one side of the second water receiving tray 31, extending away from the bottom of the second water collecting tank 311. The second guide plate 33 and the second water receiving tray 31 can be of separate design or of integrated design.

[0063] like Figure 3 As shown, the second guide plate 33 is arranged facing the fin 111. In actual application, the condensed water blown by the wind is guided to the fin 111 through the second guide plate 33 and then falls back into the second water receiving tray 31, thereby preventing the wind from blowing the water in the second water receiving tray 31 into the fan chamber 9.

[0064] In one embodiment, the top of the second guide plate 33 is provided with a folded edge portion bent toward the fin 111. The design of the folded edge portion ensures that when the fan is running, the second guide plate 33 can effectively change the airflow path, thereby being more conducive to redirecting the condensed water to the surface of the fin 111.

[0065] In one embodiment, water baffles 4 are provided on both the front and rear sides of the condenser body 1 .

[0066] like Figure 3 and Fig. 9 As shown, in this embodiment, a water baffle 4 is provided on the rear side of the cooler body 1, and the water baffle 4 is fixed to the side plate 113 with screws, and is used to guide the condensed water at the corner part of the cooler to the second water receiving tray 31 below, so as to prevent the condensed water therefrom from entering the fan cavity 9.

[0067] like Figures 1 to 12 As shown, an embodiment of the present invention further provides a V-shaped heat exchange device, including an upper connecting member 6, a front connecting member 7, a rear connecting member 8 and the above-mentioned surface cooler structure, there are two surface cooler structures, the two surface cooler structures are arranged in an inverted V shape, the upper connecting member 6, the front connecting member 7, and the rear connecting member 8 are all plate-like structures, the upper connecting member 6 is connected to the top sides of the two surface cooler structures by screws, the front connecting member 7 is connected to the front sides of the two surface cooler structures by screws, and the rear connecting member 8 is connected to the rear sides of the two surface cooler structures by screws.

[0068] from Fig.12 It can be seen that Fig.12 The inclined arrow in the middle indicates the wind inlet direction, and the vertical arrow indicates the wind outlet direction. The first water receiving tray 21 and the second water receiving tray 31 can effectively prevent condensed water from gathering into large water droplets and then drifting into the fan cavity 9, effectively protecting the components inside the fan cavity 9, while also keeping the humidity in the air duct unchanged. At the same time, the first water receiving tray 21 and the second water receiving tray 31 are respectively provided with the first guide plate 22 and the second guide plate 33, which can effectively prevent the water blown out by the wind from entering the fan cavity 9.

[0069] The embodiment of the present invention further provides a computer room air conditioner, comprising the above-mentioned V-shaped heat exchange device. Except for the above-mentioned V-shaped heat exchange device, the rest of the structure of the computer room air conditioner can be the same as that on the market, and the rest of the structure will not be described in detail here.

[0070] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
