Detailed Implementation

[0021] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] The embodiments provided by this utility model are as follows: Figures 1-5 As shown, a dual-outlet evaporative air cooler includes a housing 10, a frame 20 fixedly installed inside the housing 10, a fan unit 30 fixedly installed on the upper surface of the inner wall of the housing 10, a water distribution trough 40 surrounding the fan unit 30, the water distribution trough 40 being fixedly installed on the frame 20, a plurality of water inlets 50 being provided on the water distribution trough 40, and a plurality of water outlets 60 being provided on the outer walls around the water distribution trough 40, and a water storage tank 70 and a water pump fixedly installed inside the housing 10. 80, water storage tank 70 and water pump 80 are located below the frame 20. The input end of water pump 80 is connected to water storage tank 70. The output end of water pump 80 passes through the bottom of frame 20 and is connected to several water inlets 50. Several air inlets 90 are opened on the side walls around the box 10. The air inlets 90 are located on the outside of frame 20. An air outlet 100 is opened on the top of box 10. The position of air outlet 100 matches that of fan unit 30.

[0023] In use, the water pump 80 is started, pumping water from the water storage tank 70 through its output end into several inlets 50 on the water distribution trough 40. After entering the water distribution trough 40, the water overflows evenly from several outlets 60 on its outer side walls, flows down along the outer side walls of the water distribution trough 40, and comes into contact with the outer wet curtain (not shown in the figure). The water flows down the corrugated surface of the wet curtain. Due to the high water absorption and porous structure of the wet curtain material, the water forms a very thin but uniform water film. The fan unit 30 starts running, generating negative pressure suction inside the housing 10. Hot air from the outside is drawn in from several air inlets 90 on the side walls of the housing 10. When this hot air flows through the frame 20, it passes through the wet curtain. During this process, the air comes into full contact with the cold water film, the water evaporates and absorbs the heat in the air, thus significantly reducing the temperature of the air itself. The cooled air is then discharged from the air outlet 100 at the top of the housing 10 under the guidance of the fan unit 30 and enters the outside space.

[0024] Preferably, the fan unit 30 includes two cooling fans 31, which are fixedly mounted on the upper surface of the inner wall of the housing 10 and symmetrically arranged along the vertical center of the housing 10. The outer side of the cooling fans 31 is integrally formed with a protective cover 32. This arrangement can generate a larger and more uniform air volume and airflow field, avoid the wind dead zone that may exist in a single cooling fan 31, and improve the cooling efficiency. The protective cover 32 plays a safety protection role, effectively preventing water from splashing in or foreign objects from contacting the high-speed rotating fan blades, thus ensuring the safe operation of the equipment and enhancing the reliability and safety of the product.

[0025] Preferably, a buffer shell 110 is fixedly installed inside the water distribution tank 40. The position and number of buffer shells 110 match the water inlet 50. A flow port 120 is opened on the side wall of the buffer shell 110. The buffer shell 110 buffers the incoming water flow and avoids impact. Since the position of the buffer shell 110 corresponds one-to-one with the water inlet 50, the high-pressure water flow from the water pump 80 is first injected into the buffer shell 110. Its internal space buffers and dissipates the kinetic energy of the water flow. Then the water flow flows smoothly into the water distribution tank 40 through the flow port 120 on the side wall. This effectively prevents the high-pressure water flow from spraying out directly and splashing, ensuring the stability of the water level and the uniformity of the overflow from the water outlet 60, making the formed water curtain more complete and stable, thereby improving the heat exchange efficiency and cooling effect.

[0026] Preferably, a plurality of guide plates 130 are fixedly installed on the frame 20. The guide plates 130 are located below the outer wall of the water distribution tank 40. The position of the guide plates 130 matches the water outlet 60. A reinforcing member 140 is fixedly installed on the guide plate 130 and fixed to the inner wall of the housing 10. The guide plates 130 are located below the water outlet 60 and can accurately receive the water flowing down from the water outlet 60 and guide it to the outer wet curtain (not shown in the figure). The water flows down the corrugated surface of the wet curtain from top to bottom. Due to the high water absorption and porous structure of the wet curtain material, the water will form a very thin but uniform water film, which maximizes the contact area between water and air, improves heat exchange efficiency and cooling effect.

[0027] Preferably, an inlet pipe 150 and an outlet pipe 160 are fixedly installed inside the housing 10. One end of the inlet pipe 150 passes through the side wall of the housing 10 and extends to the outside of the housing 10, while the other end is located above the water storage tank 70. One end of the outlet pipe 160 passes through the side wall of the housing 10 and extends to the outside of the housing 10, while the other end is connected to the bottom of the water storage tank 70. The inlet pipe 150 is used to automatically or manually replenish fresh water when the water level in the water storage tank 70 is too low. The outlet pipe 160 is used to periodically drain and replace the water stored in the water storage tank 70 to prevent water quality deterioration, microbial growth, or scale formation, thereby indirectly ensuring the cooling efficiency and air cleanliness of the equipment.

[0028] Preferably, a reinforcing plate 170 is fixedly installed on the inner wall around the water storage tank 70, and a reinforcing rib 180 is fixedly installed on the bottom of the water storage tank 70. The reinforcing plate 170 and the reinforcing rib 180 improve the structural strength and pressure resistance of the water storage tank 70. The water storage tank 70 contains a large amount of water for a long time, which puts great pressure on its tank wall and bottom. The reinforcing plate 170 and the reinforcing rib 180 can effectively resist this pressure, prevent the water storage tank 70 from expanding, deforming or cracking, improve the reliability of the water storage tank 70 in long-term use, and avoid the risk of water leakage.

[0029] Preferably, a return port 190 is provided at the bottom of the frame 20. The return port 190 is located directly above the water storage tank 70. The return port 190 is used to collect circulating water and return it smoothly to the water storage tank 70. The return port 190 is located directly above the water storage tank 70, providing a return channel for the water flowing down from the guide plate 130 and the small amount of water that may condense inside the tank 10. This ensures the effective recycling of circulating water, avoids the accumulation of circulating water in other positions at the bottom of the frame 20, and keeps the inside of the equipment dry and clean.

[0030] Preferably, support bases 200 are fixedly installed on both sides of the bottom of the housing 10. The support bases 200 support the entire equipment and keep it at a certain distance from the ground. The support bases 200 are made of metal or high-strength plastic, which provides stable support for the housing 10, prevents it from directly contacting the ground, and avoids corrosion of the bottom of the housing 10 due to ground moisture. At the same time, the raised space also facilitates ventilation and daily inspection and cleaning of the bottom of the equipment.

[0031] The dual-outlet evaporative air cooler of this invention features a fan unit 30 fixedly mounted on the upper surface of the inner wall of a housing 10. A water distribution trough 40 is arranged around the outer side of the fan unit 30 and fixedly mounted on a frame 20. The water distribution trough 40 has several water inlets 50 and several water outlets 60 on its outer side walls. A water storage tank 70 and a water pump 80 are fixedly mounted inside the housing 10. Several air inlets 90 are located on the side walls of the housing 10, and an air outlet 100 is located on the top of the housing 10. This dual-outlet evaporative air cooler forms a large-area uniform water film through the water distribution trough 40 and multiple water outlets 60, increasing the contact area between air and water and improving heat exchange efficiency.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
