Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a vertical air cooler. Background Technology

[0002] With global warming and increasing demands for indoor air quality, the demand for refrigeration and air purification equipment is growing. Traditional evaporative air coolers typically use direct evaporative cooling, employing a fan to blow air over a humidified medium to lower the air temperature. However, these traditional designs have some shortcomings, such as: conventional air intake structures often use a single-sided opening design, which limits the surface area of ​​air in contact with the evaporative cooling pad, affecting heat exchange efficiency; existing equipment's water circulation systems often suffer from uneven water distribution and insufficient wetting of the evaporative cooling pad in certain areas, impacting the cooling effect. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a vertical air cooler, which has the characteristics of simple structure and high cooling efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A vertical evaporative air cooler includes a frame with air inlets evenly distributed on the side walls of the frame. A wet film is evenly laid on the inner side of the air inlets. An airflow channel is formed in the middle of the frame. The wet film is disposed around the airflow channel and located between the airflow channel and the air inlets. An air outlet component is installed on the frame. The air outlet component has an air outlet communicating with the airflow channel. A fan is installed above the airflow channel to deliver airflow to the air outlet.

[0006] The frame is equipped with a base at its bottom, and a water storage tank is installed inside the base. The water storage tank is equipped with a water supply system that delivers water to the wet membrane.

[0007] The water supply system includes a water pump and a water distributor connected to the top of the wet membrane.

[0008] Preferably, the water distributor includes at least two sets of water distribution pipes distributed along the vertical direction of the wet film, and the water distribution pipes include a plurality of water distribution holes.

[0009] Preferably, the water supply system further includes a water level controller installed in a water storage tank, and a pulse controller for controlling the start and stop of the water pump.

[0010] Furthermore, the frame is rectangular cylindrical, with air inlets evenly distributed on three of its sides, and the air inlets are inclined louvers.

[0011] Preferably, a filter screen is provided between the air inlet and the wet film.

[0012] Furthermore, the air outlet is in the shape of an annular shell, and its interior includes an annular accelerating air duct. The cross-section of the annular accelerating air duct is elliptical, and a guide surface is formed on one side of the annular accelerating air duct. An air outlet gap is formed at the end of the guide surface, and the air outlet gap constitutes the air outlet.

[0013] Preferably, a water supply port for supplying water to the water storage tank is provided on one side of the water storage tank.

[0014] Preferably, a control panel is provided outside the frame.

[0015] The beneficial effects of this utility model are:

[0016] 1. This vertical air cooler adopts a structural design with inclined louvered air inlets evenly opened on three sides. Combined with the wet film distributed circumferentially inside the cylindrical frame, the air fully contacts the surface of the wet film and is cooled before being blown out through the airflow channel to the air outlet. The design of the wet film significantly improves the evaporative heat exchange efficiency.

[0017] 2. The double-layer water distribution pipe design forms a three-dimensional water distribution network through two sets of upper and lower distribution, which can make the wet film surface evenly wetted. Combined with pulse control technology, the water pump adopts an intermittent water supply mode, which reduces water consumption while ensuring sufficient wet film wetting.

[0018] 3. The air outlet component is designed with a bladeless air outlet. The airflow passes through the annular acceleration duct and the guide surface and is blown out from the air outlet gap, forming the Coanda effect. This structure can reduce the turbulence of traditional direct air outlet, increase the wind speed and air delivery distance, and further improve the cooling efficiency when used indoors.

[0023] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0024] Reference Figure 1 This utility model proposes a vertical air cooler, including a frame 1. The side wall of the frame 1 is evenly provided with air inlets 10. The inner side of the air inlets 10 is evenly covered with a wet film 2. An airflow channel 4 is formed in the middle of the frame 1. The wet film 2 is disposed around the airflow channel 4 and located between the airflow channel 4 and the air inlets 10. An air outlet component 7 is installed on the frame 1. The air outlet component 7 has an air outlet 700 communicating with the airflow channel 4. A fan 5 is installed above the airflow channel 4 to deliver airflow to the air outlet 700.

[0025] Specifically, when the fan 5 is started, external airflow enters through the air inlet 10, is cooled by the wet film, and then converges and rises through the airflow channel 4 to the air outlet 700. The surface area of ​​the wet film 2 distributed circumferentially inside the cylindrical frame 1 is increased compared to the traditional single-sided air inlet structure, significantly improving the evaporative heat exchange efficiency, resulting in a more significant reduction in outlet air temperature and higher cooling efficiency. Preferably, the wet film 2 can be a metal-based wet film with a porous ceramic layer sintered on the surface of an aluminum or stainless steel substrate, with a porosity of 60-80% and a pore size of 50-200μm. It has strong corrosion resistance, is easy to clean, and has a long service life.

[0026] A base 11 is installed at the bottom of the frame 1, and a water storage tank 12 is installed inside the base 11. A water supply system 3 is installed inside the water storage tank 12 to deliver water to the wet membrane 2.

[0027] The water supply system 3 includes a water pump 30 and a water distributor connected to the top of the wet membrane 2.

[0028] The water distributor includes at least two sets of water distribution pipes 31 distributed along the vertical direction of the wet film 2, and the water distribution pipes 31 include several water distribution holes.

[0029] Furthermore, the water distribution pipes 31 are divided into two groups. One group is arranged at the top of the wet membrane 2 to spray the top or upper part of the wet membrane 2, and the other group is arranged in the middle of the wet membrane 2. The two groups form a three-dimensional water distribution network. Experimental tests show that the surface wetting uniformity of the wet membrane 2 can reach more than 95%.

[0030] The water supply system 3 also includes a water level controller 32 installed in the water storage tank 12, and a pulse controller for controlling the start and stop of the water pump 30.

[0031] Specifically, the water level controller 32 can monitor the water level in the water storage tank 12 in real time to remind users to replenish water in time; the water pump 30 combines pulse control technology and adopts an intermittent water supply mode. Combined with different speeds or modes of the air cooler, it can reduce water consumption and energy consumption while ensuring that the wet film 2 is fully wetted.

[0032] Furthermore, when the wet membrane 2 is a metal-based wet membrane, a magnetizer can be added to the water storage tank 12 to reduce scale buildup on the metal surface after the water supply is magnetized, thereby further optimizing the air outlet efficiency.

[0033] Reference Figure 2 The frame 1 is rectangular cylindrical, with air inlets 10 evenly distributed on three of its sides. The air inlets 10 are inclined louvers. Specifically, one side of the frame 1 is provided with an openable window to facilitate the maintenance, repair, and cleaning of the parts inside the frame 1.

[0034] Optionally, the opening ratio of the louvered air inlet 10 is 50%-60%, and the blade tilt angle θ is 30°-60°. Furthermore, the louvered air inlet 10 can also be designed to open and close electrically, controlling the air intake efficiency of the air inlet according to different gears or modes of the air cooler. When not in use, the louver can also be closed to reduce the entry of dust.

[0035] Preferably, a filter 100 is provided between the air inlet 10 and the wet film 2. The filter 100 effectively removes dust and other particulate matter from the air, further improving air quality. This filter can be replaced or cleaned as needed to ensure the cleanliness and working efficiency of the air cooler during long-term use.

[0036] Reference Figure 2 , Figure 3 The air outlet component 7 is in the shape of an annular shell, and its interior includes an annular acceleration air duct 71. The cross-section of the annular acceleration air duct 71 is elliptical. A guide surface 70 is formed on one side of the annular acceleration air duct 71, and an air outlet gap is formed at the end of the guide surface 70. The air outlet gap constitutes the air outlet 700.

[0037] Furthermore, the air outlet component 7 is designed with a bladeless air outlet. The airflow passes through the annular acceleration duct 71, the guide surface 70, and is blown out through the air outlet gap 700, forming the Coanda effect. This structure can reduce the turbulence of traditional direct-blowing air outlets, thereby increasing the wind speed and air delivery distance, further improving the cooling and air blowing efficiency when used indoors. On the other hand, the operating noise of the air cooler can also be reduced.

[0038] A water inlet 110 for supplying water to the water storage tank 12 is provided on one side.

[0039] Reference Figure 2 A control panel 6 is installed outside the rack 1. Specifically, different operating modes, such as blowing mode or cooling mode, can be adjusted through the control panel 6, as well as the fan speed, to adapt to different indoor environments and user needs.
