Description

Technical Field

[0001] This utility model relates to the field of evaporative cooling industrial air conditioning technology, and in particular to a special outdoor unit for evaporative cooling industrial air conditioning. Background Technology

[0002] Evaporative cooling industrial air conditioners are typically equipped with dedicated outdoor units. These outdoor units combine a fan and a wet curtain, making them an economical and environmentally friendly cooling system. Through the combination of evaporative cooling and fan ventilation, humidification, and cooling, they achieve both cooling and air exchange, with relatively low installation and operating costs.

[0003] Since evaporative cooling pads require water flow, a water pump and water tank are installed in the outdoor unit of an evaporative cooling industrial air conditioner. The pump delivers water from the tank to the evaporative cooling pads. To ensure the water flows evenly onto the pads, a water distributor is needed to distribute the pumped water evenly. Existing water distributors typically include a main water pipe and multiple outlets evenly distributed on the main pipe. Because the evaporative cooling pads need to connect to the outside environment, dust, sand, and other impurities inevitably exist in the air. These impurities can flow back into the main water pipe after water circulation, potentially clogging the outlets and affecting water circulation, thus impacting the cooling effect of the evaporative cooling pads. Therefore, there is a need for an evaporative cooling industrial air conditioner outdoor unit that can reduce impurities such as sand in the water flow to ensure proper water circulation. Utility Model Content

[0004] The purpose of this utility model is to provide a special outdoor unit for evaporative cooling industrial air conditioners, which aims to solve the problem of water circulation being affected by water outlet blockage in existing evaporative cooling industrial air conditioner outdoor units.

[0005] To achieve the above objectives, this utility model provides a special outdoor unit for evaporative cooling industrial air conditioning, including a casing and a water tank, a water pump, a wet curtain, and a water distributor installed inside the casing. The water pump is used to pump water from the water tank to the water distributor via a water pipe. After being diverted by the water distributor, the water falls onto the wet curtain, and the water in the wet curtain falls back into the water tank to achieve water circulation and cooling. The water distributor includes a main body, which is provided with an inlet, a diversion chamber, a sand filter, and an outlet. The inlet is connected to the water pump. The diversion chamber is located outside the inlet and has at least two diversion channels. A sand filter is installed at the end of each diversion channel and is connected to the outlet. The height of the end of the diversion channel is at the same level as the outlet. The sand filter is lower than the outlet. A detachable sand filter is installed in the sand filter, and multiple sand baffles are installed on the sand filter, which are inclined towards the direction in which the water flows into the sand filter.

[0006] Furthermore, the water inlet section includes a water inlet pipe, a sealing cover, a buffer platform, and a reset elastic element. The sealing cover is disposed in the water inlet pipe and can move up and down within the water inlet pipe. The buffer platform is disposed outside the water inlet pipe and is connected to the diversion chamber. The sealing cover is T-shaped and includes a cap and a vertical rod connected together. The edge of the cap is provided with a raised edge, and the cap is used to block the water inlet pipe. A slide is disposed in the water inlet pipe, and the vertical rod can slide in the slide. The reset elastic element is sleeved on the vertical rod, with one end of the reset elastic element abutting against the vertical rod and the other end abutting against the slide.

[0007] Furthermore, the bottom of the diversion chamber is provided with an inclined surface, with the higher part of the inclined surface located at the water inlet and the lower part of the inclined surface located at the end of the diversion channel.

[0008] Furthermore, the main body of the water distributor is equipped with an overflow channel, which is connected to the distribution chamber. A removable overflow baffle is installed at the connection between the overflow channel and the distribution chamber.

[0009] Furthermore, multiple sets of partition plates are installed at the water outlet, which evenly divide the water outlet into multiple sets of water inlets with the same width.

[0010] Furthermore, a handle is provided on the sand filter.

[0011] Furthermore, the sand filter tank is equipped with a drain outlet and a magnetic base. The sand filter is equipped with a magnetic groove that fits the magnetic base. When the sand filter is installed in the sand filter tank, the drain outlet is blocked by the sand filter.

[0012] Furthermore, the main body of the distributor is equipped with a handle and a mounting base. The handle is located near the water inlet of the main body of the distributor, and the mounting bases are evenly distributed on the side of the main body of the distributor.

[0013] The outdoor unit for an evaporative cooling industrial air conditioner provided by this utility model, compared with the prior art, adopts an improved water distributor to divert the water flow. The water flow enters the diversion chamber through the water inlet, and the diversion chamber evenly divides the water flow into multiple streams and enters the diversion channel. The water flow out of the diversion channel enters the lower filter sand bar. Since the mass of impurities such as sand and dust is relatively heavy, the baffle plate in the filter sand bar can intercept these impurities, reducing the impurity content of the circulating water flow. At the same time, the lower-positioned filter sand bar can also guide the water flow to enter multiple sets of water inlets simultaneously, so that the water flow can flow evenly onto the wet curtain.

[0034] The present invention will be described in detail below with reference to specific embodiments.

[0035] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0036] like Figures 1 to 10 As shown, this utility model provides a special outdoor unit for evaporative cooling industrial air conditioning, including a casing 01 and a water tank 02, a water pump (inside the water tank 02, not shown), a wet curtain 03, and a water distributor disposed within the casing 01. The water pump is used to pump water from the water tank 02 to the water distributor via a water pipe. After being diverted by the water distributor, the water falls onto the wet curtain 03, and the water in the wet curtain 03 falls back into the water tank 02, thereby achieving water circulation and water cooling. The water distributor includes a water distributor body 04, on which a water inlet 1 and a diversion chamber 2 are provided. The sand filter tank 3 and the water outlet 4 are connected. The water inlet 1 is used to connect to the water pump. The diversion chamber 2 is located outside the water inlet 1. The diversion chamber 2 is provided with at least two diversion channels 20. The end of the diversion channel 20 is provided with the sand filter tank 3. The sand filter tank 3 is connected to the water outlet 4. The end of the diversion channel 20 is at the same level as the water outlet 4. The sand filter tank 3 is lower than the water outlet 4. The sand filter tank 3 is provided with a detachable sand filter 30. The sand filter 30 is provided with multiple sets of sand baffles 33. The sand baffles 33 are inclined in the direction of water flow into the sand filter 30.

[0037] Through the above design scheme, this type of outdoor unit for evaporative cooling industrial air conditioning uses an improved water distributor to divert the water flow. The water, pumped by a water pump, enters the diversion chamber 2 from the inlet 1, then flows through the diversion channel 20 to the sand filter tank 3, and finally flows evenly out from the outlet 4 onto the wet curtain 03. When the water flows from the diversion channel 20 into the sand filter tank 3, due to the lower position of the sand filter tank 3, the water flow forms a vortex. Furthermore, because the mass of impurities such as sand and dust is relatively large, under the action of the vortex and gravity, the large mass... Impurities will fall below the baffle plate 33 due to its obstruction. Since the baffle plate 33 is set at an angle, the water flow velocity below the baffle plate 33 is low, making it difficult for the deposited impurities to be carried up again, thereby reducing the impurity content in the water flow during water circulation. At the same time, since the filter tank is located at a low position, when the water flows into the filter tank 3 from the diversion channel 20, it will first fill the filter tank 3 and then flow out from the outlet 4. This ensures that the outlets 4 at different positions can discharge water evenly, avoiding insufficient water flow in some wet curtains 03 that would affect heat dissipation efficiency.

[0038] In this embodiment, the water inlet 1 includes a water inlet pipe 10, a sealing cover 13, a buffer platform 11, and a reset elastic member 16. The sealing cover 13 is disposed in the water inlet pipe 10 and can move up and down in the water inlet pipe 10. The buffer platform 11 is disposed outside the water inlet pipe 10 and is connected to the diversion chamber 2. The sealing cover 13 is T-shaped and includes a cap 14 and a vertical rod 15 connected to each other. The cap 14 has a raised edge 17 on its edge and is used to block the water inlet pipe 10. A slide 12 is disposed in the water inlet pipe 10, and the vertical rod 15 can slide in the slide 12. The reset elastic member 16 is sleeved on the vertical rod 15, with one end of the reset elastic member 16 abutting against the vertical rod 15 and the other end abutting against the slide 12.

[0039] Since there are usually more than two wet curtains 03 inside the housing 01, there are also more than two water distributors that match them. However, considering the machining and assembly precision, the height of the multiple water distributors may not be able to be kept at the same level. When the water pump pumps water, the water distributor at the lower position will release water first, while the water distributor at the higher position will release water later. In addition, the water output of water distributors at different heights will also deviate, which will result in different water flow rates for wet curtains 03 at different positions.

[0040] Through the above design scheme, under the action of the reset elastic element 16, the cap 14 tends to close the inlet pipe 10. When the water flows to the lower inlet pipe 10, under the obstruction of the cap 14, the water will not flow directly from the inlet pipe 10 into the diversion chamber 2. Instead, the water will continue to flow to the higher inlet pipe 10 until all inlet pipes 10 are filled with water. When all inlet pipes 10 are filled, as the water pump continues to pump water, the water pressure in the connected inlet pipes 10 continues to increase. When the water pressure in the inlet pipes 10 reaches a certain threshold, the caps 14 in all diverters are opened simultaneously. Since the water pressure at various points in the pipes is basically the same, the opening degree of the caps 14 is also basically the same, ensuring that the water output of diverters at different positions remains consistent. The raised edge 17 of the cap 14 can guide the water flow to fall onto the buffer platform 11, preventing the water flow from splashing outside the diversion chamber 2 due to excessive impact force.

[0041] In this embodiment, the bottom of the diversion chamber 2 is provided with an inclined surface, the higher part of the inclined surface is located at the water inlet 1, and the lower part of the inclined surface is located at the end of the diversion channel 20.

[0042] The above design scheme can guide the direction of water flow, ensuring that the water entering the diversion chamber 2 can flow out from the diversion channel 20, reducing the amount of water accumulation in the diversion chamber 2 after shutdown.

[0043] In this embodiment, an overflow channel 6 is provided on the main body 04 of the water distributor. The overflow channel 6 is connected to the diversion chamber 2. A detachable overflow baffle 60 is provided at the connection between the overflow channel 6 and the diversion chamber 2.

[0044] With the above design, the overflow channel 6 on the main body 04 of the water distributor can prevent the water level in the distribution chamber 2 from being too high when it is accidentally blocked. When the distribution chamber 2 needs to be cleaned, the user can directly remove the overflow baffle 60 so that all the water in the distribution chamber 2 can flow out through the overflow channel 6.

[0045] In this embodiment, multiple sets of partition plates 40 are provided at the water outlet 4, and the partition plates 40 evenly divide the water outlet 4 into multiple sets of water inlets 41 with the same width.

[0046] The partition plate 40 and the water inlet 41 are used to divide the water outlet 4 and guide the water to flow out evenly. Since this design is existing technology and is not an improvement point of this embodiment, it is not described in detail in this embodiment.

[0047] In this embodiment, a handle 34 is provided on the sand filter 30.

[0048] In this embodiment, a drain outlet 32 ​​is provided in the sand filter tank 3, and a magnetic seat 31 is also provided in the sand filter tank 3. A magnetic groove 35 that fits the magnetic seat 31 is provided on the sand filter 30. When the sand filter 30 is installed in the sand filter tank 3, the drain outlet 32 ​​is blocked by the sand filter 30.

[0049] After prolonged use, a large amount of impurities will accumulate in the filter sand tray 30, requiring cleaning by the user. With the above design, when cleaning the main body 04 of the water distributor is needed, the user can first remove the main body 04 and then separately disassemble the filter sand tray 30 for cleaning. The handle 34 on the filter sand tray 30 can be easily removed, allowing the user to directly lift or place the filter sand tray 30 using the handle 34.

[0050] The magnetic base 31 in the sand filter tank 3 and the magnetic groove 35 on the sand filter 30 can use magnetic force to make the sand filter 30 stick tightly to the sand filter tank 3. At this time, the drain outlet 32 ​​is completely blocked by the sand filter 30, keeping the drain outlet 32 ​​in a closed state to prevent water from seeping out of the drain outlet 32 ​​during normal operation. When cleaning is required, the user can remove the sand filter 30 to open the drain outlet 32, and the sewage flowing into the sand filter tank 3 can flow directly out of the drain outlet 32, preventing sewage accumulation from affecting water quality.

[0051] In this embodiment, the main body 04 of the water distributor is provided with a handle 5 and a mounting base 7. The handle 5 is located near the water inlet 1 of the main body 04 of the water distributor, and the mounting base 7 is evenly distributed on the side of the main body 04 of the water distributor.

[0052] With the above design, the mounting base 7 is used to fix the water distributor body 04 on the housing 01, and the handle 5 can be easily gripped during disassembly and assembly, making it convenient to disassemble and assemble the water distributor body 04.

[0053] The outdoor unit for an evaporative cooling industrial air conditioner provided by this utility model, compared with the prior art, adopts an improved water distributor to divert the water flow. The water flow enters the diversion chamber 2 through the water inlet 1, and the diversion chamber 2 divides the water flow evenly into multiple streams and enters the diversion channel 20. The water flow out of the diversion channel 20 enters the lower sand filter 30. Since the mass of impurities such as sand and dust is relatively heavy, the sand baffle 33 in the sand filter 30 can intercept these impurities, reducing the impurity content of the circulating water flow. At the same time, the lower sand filter 30 can also guide the water flow to enter multiple sets of water inlets 41 simultaneously, so that the water flow can flow evenly onto the wet curtain 03.

[0054] Where there is no conflict, the above embodiments and features can be combined with each other.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
