Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a multi-faceted air intake cooling fan. Background Technology

[0002] Traditional evaporative air coolers typically consist of core components such as a water tank, water pump, evaporative cooling pad, and fan. The water pump draws water from the tank and delivers it to the top or above the evaporative cooling pad, where gravity causes the water to flow across the surface, forming a moist water film. The fan then drives air through the moistened pad, where the heat in the air is absorbed by the evaporating water, thus lowering the air temperature and generating a cool airflow that is expelled from the air.

[0003] However, most existing air coolers use a single air intake surface and a single wet curtain design. This structure limits the amount of air intake, and the total amount of air flowing through the wet curtain for heat exchange per unit time is limited, making it difficult to significantly improve the overall cooling capacity and air delivery efficiency. Utility Model Content

Detailed Implementation

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] A multi-faceted air intake fan, such as Figure 1-10As shown, the system includes a water tank 1, a water pump 2, and a wet curtain (not shown in the figure). The water inlet of the water pump 2 is connected to the water tank 1. The wet curtain is installed on multiple air inlet surfaces 3 of the cooling fan. A water distribution tray 4 is installed above the wet curtain. The water outlet of the water pump 2 is connected to the water distribution tray 4. A water distribution channel 5 is formed in the water distribution tray 4, which surrounds or penetrates the area above the wet curtain. The water distribution channel 5 is used to guide and distribute the water in the water distribution tray 4 to the corresponding wet curtain. The evaporative cooling pad is located at the rear end of the air inlet surface 3 and corresponds to the water outlet of the water channel 5. The water trays 4 are distributed above the evaporative cooling pads in each direction. The water pump 2 draws water from the water tank 1 to the water tray 4 and continuously injects water into the water tray 4, pushing the water flow along the water channel 5 on the water tray 4 until it reaches the water outlet corresponding to the position of the evaporative cooling pad in each direction. The water flows through the surface of each evaporative cooling pad under the action of gravity. This design can supply water to the evaporative cooling pads in different directions in a uniform, stable and efficient manner, so that the natural wind coming from multiple directions can pass through the moist evaporative cooling pads, improving the cooling capacity and air supply efficiency of the whole unit.

[0040] Preferably, the water tray 4 is provided with a plurality of water chambers 6, which are distributed above the wet curtain corresponding to each air inlet surface 3. Each water chamber 6 has at least one door 61 that connects to the water flow channel 5. Multiple water chambers 6 are configured in each air inlet surface 3 direction, forming a multi-point water flow for each wet curtain, improving the wetting efficiency of the wet curtain. The side walls of the water chambers 6 are higher than the water flow channel 5, and water flows only through the doors 61. The height of the doors 61 is slightly higher than that of the water flow channel 5. When the water flow channel 5 is filled to a certain height, the water in the water flow channel 5 flows forward while entering the water chambers 6 through the doors 61 of each water chamber 6. This structure significantly reduces water flow resistance, allowing the water pump 2 to drive the water flow with only a small pressure difference. This not only reduces the size of the water pump 2 and saves installation space, but also directly reduces energy consumption.

[0041] Preferably, a drain hole 62 is provided through the drain chamber 6, and an inclined guide surface 621 is provided on the drain hole 62, the inclined guide surface 621 being inclined towards the wet curtain. The drain hole 62 corresponds to the position of the wet curtain, the drain hole 62 is rectangular, and the inclined guide surface 621 is four trapezoidal surfaces formed by the outward extension of each side of the rectangle. Water in the drain chamber 6 flows quickly to the wet curtain through the inclined guide surface 621 of the drain hole 62, improving the wet curtain's dehumidification efficiency.

[0042] Preferably, a guide block 63 is provided between the door 61 and the drain hole 62. The guide block 63 is provided with a first guide surface 631, which guides the water entering the drain chamber 6 towards the drain hole 62. The first guide surface 631 is inclined and tilted towards the drain hole 62. After the water in the water channel 5 enters the door 61, it flows along the first guide surface 631 of the guide block 63 to the drain hole 62, and then flows out of the drain hole 62 through the inclined guide surface 621 of the drain hole 62. This improves the efficiency of water flowing into the drain hole 62 and makes the wet curtain wet more efficiently.

[0043] Preferably, the water tray 4 is provided with an upper water tank 7 to accommodate the water pump 2, and the upper water tank 7 is connected to the water flow channel 5. The water pump 2 is installed in the upper water tank 7, and the upper water tank 7 has at least one water outlet. The water pump 2 draws water from the water tank 1 into the upper water tank 7, and then enters the water flow channel 5 through the water outlet. The structure is compact, the layout is reasonable, and it is easy to implement.

[0044] Preferably, the cooling fan has three air inlet surfaces 3, and the water tray 4 is U-shaped, including a left water tray 41, a right water tray 42, and a middle water tray 43, which correspond to the wet curtains on the three air inlet surfaces 3, respectively. The water pump 2 is located outside the middle water tray 43 and is connected to the middle water tray 43. The water pump 2 drives water to flow from the middle water tray 43 to the left water tray 41 and the right water tray 42. This ensures that the wet curtains located below the left water tray 41, the right water tray 42, and the middle water tray 43 are evenly wetted, allowing natural air entering from the left, right, and front directions to pass through the wetted wet curtains, thereby improving the overall cooling capacity and air delivery efficiency of the unit.

[0045] Preferably, a support frame 8 is provided outside the water tray 4. The upper end of the support frame 8 extends above the water channel 5, enclosing the water channel 5 and preventing it from being completely exposed to the air, thus providing a dustproof effect. The lower end of the support frame 8 is mounted on the water tank 1 and engages with the air inlet surface 3, which is located outside the side wall of the support frame 8. The evaporative cooling pad is fixed to the support frame 8 and located between the support frame 8 and the air inlet surface 3. The water outlet of the water channel 5 is located between the support frame 8 and the air inlet surface 3, corresponding to the position of the evaporative cooling pad. By providing the support frame 8, the overall support effect of the machine is improved.

[0046] Preferably, a first limiting rib 431 is provided in the middle section of the water tray 4. The first limiting rib 431 protrudes upward from the support frame 8. The support frame 8 has a first through hole 81 through which the first limiting rib 431 passes. A limiting plate 82 is provided above the first through hole 81. The first limiting rib 431 and the limiting plate 82 cooperate with each other to fix the water tray 4 on the support frame 8. After the first limiting rib 431 on the water tray 4 enters the first through hole 81, it engages with the limiting plate 82. Second limiting ribs 432 are provided at both ends of the water tray 4. The second limiting ribs 432 protrude upward from the support frame 8. The support frame 8 has a second through hole through which the second limiting ribs 432 pass. After the second limiting ribs 432 on the water tray 4 enter the second through hole, they engage with the upper wall of the second through hole. By setting the first limiting rib 431 and the second limiting rib 432, the support frame 8 and the water tray 4 are fixedly connected. The structure is simple and the fixing effect is good.

[0047] Preferably, the air inlet surface 3 is composed of a left side cover 31, a middle cover 32, and a right side cover 33. One end of the left and right side covers extends between the water tray 4 and the middle cover 32, forming an installation channel 34 connecting the left and right side covers and the water tray 4. The left and right side covers and the water tray 4 are fixedly connected through the installation channel 34. Each of the left and right side covers has a protruding insert 35 extending along its length. The support frame 8 is provided with a socket 83 corresponding to the position of the insert 35. The insert 35 and the socket 83 cooperate with each other to fix the support frame 8 to the left side cover 31, the middle cover 32, and the right side cover 33. Bolts are used to fix the left side cover 31, the water tray 4, and the middle cover 32 to the mounting channel 34, respectively. The right side cover 33, the water tray 4, and the middle cover 32 are also fixedly connected. The open end of the socket 83 is provided with a fourth guide surface 831, which is inclined and tilted inward towards the socket 83. The insert 35 is provided with a fifth guide surface 351, which is parallel to the fourth guide surface 831. The fourth guide surface 831 and the fifth guide surface 351 guide and cooperate to move the insert 35 into the socket 83. Through the above structure, the support frame 8 is better fixed to the left side cover 31, the middle cover 32, and the right side cover 33, and the structure is simple.

[0048] Preferably, the support frame 8 is provided with a mounting groove 84 at one end where it joins with the left and right side covers. The mounting groove 84 is provided with a protruding plate 85. The protruding plate 85 is provided with a second guide surface 851 that is inclined toward the mounting groove 84. The left and right side covers are provided with a slider 30 that protrudes and corresponds to the mounting groove 84. The slider 30 is provided with a positioning groove 301 that allows the protruding plate 85 to enter. The opening end of the positioning groove 301 is provided with a third guide surface 302. The second guide surface 851 and the third guide surface 302 guide and cooperate to move the slider 30 into the mounting groove 84. The protruding plate 85 is integrally formed with the mounting groove 84 and constitutes the side wall of the mounting groove 84. The second guide surface 851 is located at the opening end of the protruding plate 85 near the mounting groove 84. The second guide surface 851 is parallel to the third guide surface 302, so that the slider 30 slides into the mounting groove 84. At this time, the protruding plate 85 slides into the positioning groove 301 and stops the slider 30 to complete the fixation of the support frame 8 and the left and right side covers. The structure is simple and the fixing effect is good.
