Description

Technical Field

[0001] This utility model belongs to the field of air cooler technology, specifically relating to an indoor-installed air cooler. Background Technology

[0002] An evaporative air cooler, also known as a wet curtain, is a device that uses the principle of water evaporation to absorb heat and cool the air. Specifically, the air cooler contains a wet curtain, and a water pump delivers water to the top of the wet curtain, evenly wetting the entire curtain. When hot air passes through the wet curtain, the water absorbs heat from the air, lowering the air temperature, and finally, the cool air is delivered into the room by a fan.

[0003] To improve cooling efficiency and maintain indoor air quality, some existing evaporative air coolers are installed outdoors. These coolers draw in outdoor air, cool it through evaporative cooling pads, and then deliver it indoors. These coolers typically draw in air from all sides, thus requiring outdoor installation to ensure the intake of only outdoor air. However, installing evaporative air coolers outdoors not only affects the building's appearance but also makes installation and maintenance difficult and inconvenient. Furthermore, some buildings do not allow the installation of evaporative air coolers on their exterior walls, further limiting their use. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an indoor-installed air cooler.

[0005] To achieve the above objectives, this utility model discloses an indoor-installed evaporative air cooler, including a housing and a fan and a wet curtain disposed within the housing. The housing has an air inlet and an air outlet, which are located on two opposite side walls of the housing. The air inlet, wet curtain, fan and air outlet are arranged in sequence. The wet curtain is V-shaped and includes a first wet curtain and a second wet curtain. One end of the first wet curtain is connected to one end of the second wet curtain, and the other ends of the first wet curtain and the second wet curtain are both connected to the inner sidewall of the housing.

[0006] Preferably, the connection point between the first wet curtain and the second wet curtain is located near the air inlet, and the other ends of the first wet curtain and the second wet curtain are both located near the air outlet. The air inlet surface of the evaporative cooling pad is detachably connected to a filter screen.

[0007] Preferably, the air inlet surface of the wet curtain is provided with an upper slot and a lower slot, the slots of the upper slot and the lower slot are arranged opposite to each other, and the top and bottom of the filter screen are respectively secured in the upper slot and the lower slot; The upper and lower card slots are both through-holes at their ends near the air outlet.

[0008] Preferably, the length of the filter screen is greater than the length of the upper slot and the lower slot.

[0009] Preferably, there are multiple filter screens arranged sequentially from top to bottom, and the number of upper and lower slots is equal to the number of filter screens.

[0010] Preferably, the first and second wet curtains are arranged symmetrically.

[0011] Preferably, both the first and second wet curtains are equipped with water pipes for distributing water to the wet curtains.

[0012] Preferably, the outer side of the air inlet is provided with swing blades.

[0013] Preferably, the bottom of the housing is provided with a mounting base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model of an air cooler has only one air inlet and one air outlet, which are located on two opposite side walls of the casing. During installation, the main structure of the air cooler can be installed indoors. Simply align the air inlet side with the opening in the wall or connect it to the air duct leading to the outside to ensure that the air cooler can draw in outdoor air for cooling. Compared with installing the air cooler outdoors, this method is easier to install and maintain, has higher applicability, and does not affect the appearance of the building.

[0015] The air inlet, evaporative cooling pad, fan, and air outlet are arranged in sequence, with the fan located behind the evaporative cooling pad. When the fan is running, a negative pressure is generated between the air inlet and the evaporative cooling pad, and between the evaporative cooling pad and the fan. This actively draws outdoor air into the evaporative cooling fan and cools it through the evaporative cooling pad. This allows the outdoor air to flow evenly and fully across the entire surface of the evaporative cooling pad, maximizing the use of the evaporative cooling capacity of the evaporative cooling pad and improving the cooling effect.

[0016] The V-shaped wet curtain structure design increases the effective evaporation area, improving evaporation efficiency and cooling effect. Attached Figure Description

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] An indoor-mounted evaporative air cooler, see [link / reference] Figures 1-5 The system includes a housing 100 and a fan 200 and an evaporative cooling pad 300 disposed within the housing 100. The housing 100 has an air inlet 110 and an air outlet 120, which are located on two opposite side walls of the housing 100. The air inlet 110, evaporative cooling pad 300, fan 200, and air outlet 120 are arranged sequentially from the air inlet 110 to the air outlet 120. When the fan 200 operates, it blows air into the room, creating negative pressure between the air inlet 110 and the evaporative cooling pad 300, and between the evaporative cooling pad 300 and the fan 200. This actively draws outdoor air into the air cooler and cools it through the evaporative cooling pad 300. This allows the outdoor air to flow evenly and fully across the entire surface of the evaporative cooling pad 300, maximizing the utilization of the evaporative cooling capacity of the evaporative cooling pad 300 and improving the cooling effect. The above-mentioned evaporative air cooler has only one air inlet 110 and one air outlet 120. The air inlet 110 and the air outlet 120 are respectively located on two opposite side walls of the housing 100. During installation, the main structure of the evaporative air cooler is installed indoors. Then, one side of the air inlet 110 is aligned with the opening in the wall or connected to the air duct leading to the outside, so that the air inlet 110 of the evaporative air cooler is connected to the outside, ensuring that the evaporative air cooler can draw in outdoor air for cooling. Compared with installing the evaporative air cooler outdoors, this method is easier to install and maintain, has higher applicability, and does not affect the appearance of the building.

[0020] In practice, the installation location of the evaporative air cooler indoors can be set according to needs. It can be installed on the floor or mounted on the wall using a mounting bracket. When installed indoors, the air inlet can be installed near a window, or an air inlet duct can be connected to the air inlet and then connected to the outside to draw in fresh air from the outside and bring it indoors.

[0021] The evaporative cooling pad 300 is V-shaped and includes a first evaporative cooling pad 310 and a second evaporative cooling pad 320. One end of the first evaporative cooling pad 310 is connected to one end of the second evaporative cooling pad 320, and the other ends of both the first evaporative cooling pad 310 and the second evaporative cooling pad 320 are attached to the inner wall of the housing 100. The fan 200 is located between the ends of the first evaporative cooling pad 310 and the second evaporative cooling pad 320. The V-shaped evaporative cooling pad 300 structure design increases the effective evaporation area, improves the evaporation efficiency, and enhances the cooling effect.

[0022] The housing 100 contains two water distribution pipes 150, which are located above the first evaporative cooling pad 310 and the second evaporative cooling pad 320, respectively, and distribute water to the two evaporative cooling pads. A water pump delivers water to the pump, and then the water flows down through the drain holes at the bottom of the water distribution pipes 150 to the corresponding evaporative cooling pads.

[0023] Preferably, the first evaporative cooling pad 310 and the second evaporative cooling pad 320 are arranged symmetrically. The first evaporative cooling pad 310 and the second evaporative cooling pad 320 are conventional evaporative cooling pads available on the market.

[0024] In this embodiment, the connection point between the first wet curtain 310 and the second wet curtain 320 is located near the air inlet 110, and the other ends of the first wet curtain 310 and the second wet curtain 320 are both located at the corner of the air outlet 120 inside the housing 100. Figure 2 As shown, the connection point of the first evaporative cooling pad 310 and the second evaporative cooling pad 320 is located in the middle of the right inner side wall of the housing 100, and the left ends of the first evaporative cooling pad 310 and the second evaporative cooling pad 320 are located at the two left corners of the housing 100, respectively. The purpose of this arrangement is that if the connection point of the first evaporative cooling pad 310 and the second evaporative cooling pad 320 is close to the fan 200, the right end of the fan 200 will extend into the housing 100, occupying some space. This would prevent the first evaporative cooling pad 310 and the second evaporative cooling pad 320 from being of a relatively longer size, thus reducing the cooling effect. However, as described in this embodiment, the length of the first evaporative cooling pad 310 and the second evaporative cooling pad 320 can be configured to the maximum length from the middle of the right side to the left corner. The relatively larger length of the first evaporative cooling pad 310 and the second evaporative cooling pad 320 results in a larger evaporative cooling area and improves the cooling effect. Furthermore, the first evaporative cooling pad 310 and the second evaporative cooling pad 320 are located at the left corner (the side closer to the interior), which makes it easier to remove the filter screen compared to having them in the middle of the left side. The replacement and removal of the filter screen will be explained below.

[0025] The air inlet surface of the evaporative cooling pad 300 is detachably connected to a filter 350, which filters impurities in the intake air and improves the service life of the evaporative cooling pad 300. Specifically, the mounting bracket of the evaporative cooling pad 300 has an upper slot 341 and a lower slot 342, both horizontally arranged, on one side of the air inlet surface. The openings of the upper slot 341 and the lower slot 342 are opposite each other, that is, the opening of the upper slot 341 faces downward and the opening of the lower slot 342 faces upward. The ends of the upper slot 341 and the lower slot 342 near the air outlet 120 are both through-holes. When installing the filter 350, the filter 350 is inserted into the two slots from the ports of the upper slot 341 and the lower slot 342, and the top and bottom of the filter 350 are respectively secured in the upper slot 341 and the lower slot 342. Since the left end of the evaporative cooling pad 300 is located at a corner, the filter 350 can be easily inserted / removed directly at the corner of the housing 100 after removing the side panel of the housing 100 (the housing 100 has four side panels, each covered by a top cover). If the left end of the evaporative cooling pad 300 were located in the middle of the inner wall of the housing 100, it would be obstructed by the fan 200, making filter installation and replacement more difficult and inconvenient.

[0026] To facilitate the removal of the filter screen 350, the length of the filter screen 350 is greater than the length of the upper slot 341 and the lower slot 342, meaning that the end of the filter screen 350 extends out of the slot, making it easy for operators to pull out the filter screen 350 by hand. Furthermore, the filter screen 350 has a through hole 360 ​​on the side near the air outlet, and the through hole 360 ​​is sized to allow an operator's hand to pass through it, facilitating the removal of the filter screen 360.

[0027] In this embodiment, a wet curtain 300 is provided with three filter screens 350, which are arranged sequentially in the vertical direction. Correspondingly, there are three sets of upper slots 341 and lower slots 342.

[0028] In this embodiment, an oscillating blade 130 is provided on the outer side of the air inlet 110, which can alleviate the problem of external rainwater entering the air cooler and affecting the reliability of the air cooler.

[0029] In this embodiment, a mounting base 140 is provided at the bottom of the housing 100, through which the air cooler can be installed and fixed indoors. The specific installation and fixing method can be set according to actual needs, such as bolt fixing.

[0030] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
