Description

Technical Field

[0001] This utility model belongs to the field of air cooler technology, specifically relating to a water pipe structure for an air cooler, and an air cooler using the water pipe structure. Background Technology

[0002] An evaporative air cooler, also known as a cooling fan, is a device that uses the principle of water evaporation to absorb heat and cool air. For example, the wet curtain installation structure of a fresh air unit, as provided in authorization notice number CN219389911U, has a water supply tray and a water collection tray on the upper and lower sides of the wet curtain. Humidifying water drips from the drain holes at the bottom of the supply tray onto the wet curtain. As air passes over the wet curtain, it carries away the moisture, thus achieving cooling. Water that is not carried away from the wet curtain flows down into the water collection tray, and the collected water is then piped to a water tank.

[0003] The water used in the evaporative cooling pad circulates within the air cooler. As it is circulating water, it contains a lot of impurities. Furthermore, due to the small size of the drain holes in the water supply tray, impurities can easily clog the holes, preventing the water in the water supply tray from flowing smoothly to the evaporative cooling pad and thus affecting the cooling effect. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water pipe structure for a evaporative air cooler.

[0005] To achieve the above objectives, this utility model discloses a water pipe structure for a evaporative cooler, including a water inlet pipe, a water distribution pipe, and a water outlet pipe, wherein the water inlet pipe, the water distribution pipe, and the water outlet pipe are connected in sequence. The outline shape of the water distribution pipe is configured to match the horizontal cross-sectional shape of the wet curtain inside the air cooler; The bottom of the water distribution pipe is provided with multiple through holes, and the multiple holes are spaced apart along the outline shape; The radial cross-sectional area of ​​the drain pipe is smaller than that of the inlet pipe, and the area of ​​the leak hole is smaller than that of the drain pipe, so that water can flow downward through all of the leak holes.

[0006] Preferably, the diameter of the drain hole is 2mm-3.5mm, and the radial cross-sectional area of ​​the drain pipe is 20%-45% of the radial cross-sectional area of ​​the inlet pipe.

[0007] Preferably, the radial cross-sectional area of ​​the outlet of the drain pipe is 28%-50% of the radial cross-sectional area of ​​its inlet.

[0008] Preferably, the water distribution pipe is a straight pipe, and both ends of the straight pipe are connected to the water inlet pipe and the water outlet pipe, respectively.

[0009] Preferably, the water distribution pipe is an annular pipe, and the connection positions between the annular pipe and the inlet pipe and the outlet pipe are the first position and the second position, respectively. There are two flow channels in the annular pipe from the first position to the second position, and the two flow channels are of the same length.

[0010] Preferably, the water distribution pipe has a symmetrical structure, and the connection position between the water inlet pipe and the water distribution pipe is symmetrically arranged with respect to the connection position between the water outlet pipe and the water distribution pipe.

[0011] Preferably, the connection point between the water inlet pipe and the water distribution pipe and / or the connection point between the drain pipe and the water distribution pipe is located at the corner of the water distribution pipe.

[0012] Preferably, the water distribution pipe includes multiple straight pipes and multiple connectors, with two adjacent straight pipes connected by a connector. Two of the connectors are tees, each tee including a first connection port, a second connection port, and a third connection port. The first and second connection ports are respectively connected to two adjacent straight pipes, and the third connection port extends inward into the water distribution pipe. The third connection ports of the two tees are respectively connected to an inlet pipe and a drain pipe.

[0013] This invention also provides an air cooler that uses the above-described water pipe structure for an air cooler.

[0014] A evaporative air cooler includes an evaporative cooling pad and a water pipe structure disposed above the evaporative cooling pad, wherein the water pipe structure is any of the water pipe structures for evaporative air coolers described above.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the interconnected design of the inlet pipe, distribution pipe, and drain pipe, water enters the drip pipe from the inlet pipe. Part of the water flows down through the leak holes to the wet curtain (for evaporative cooling), while the other part, carrying impurities, flows out from the distribution pipe into the drain pipe, avoiding blockage at the leak holes. This achieves the self-cleaning function of the water pipe structure, significantly reducing the risk of water supply failures caused by blockages and improving the reliability of the water pipe structure.

[0016] The design of having a smaller radial cross-sectional area for the drain pipe than for the inlet pipe and a smaller area for the leakage hole than for the drain pipe ensures that water flows out at a certain pressure when passing through the leakage hole, guaranteeing the water supply to the wet curtain and the continuous cooling effect of the wet curtain.

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] A water pipe structure for an air cooler, see [link / reference] Figures 1-5 The system includes an inlet pipe 100, a distribution pipe 200, and a drain pipe 300, which are connected sequentially. Since the water pipe structure is located above the evaporative cooling pad in the air cooler, and the water supply structure (water tank / pipeline) is located below the air cooler, the inlet pipe 100 and drain pipe 300 are vertically arranged. The bottom of the inlet pipe 100 connects to the water supply structure to obtain a water source, and the bottom of the drain pipe 300 also connects to the water supply structure for water return. In this embodiment, all water pipes use existing conventional straight water pipes of equal diameter.

[0020] The outline of the water distribution pipe 200 is configured to match the horizontal cross-sectional shape of the evaporative cooling pad inside the air cooler. For example, if the horizontal cross-sectional shape of the evaporative cooling pad is annular, then the outline of the water distribution pipe 200 is also annular; if the horizontal cross-sectional shape of the evaporative cooling pad is strip-shaped, then the outline of the water distribution pipe 200 is also strip-shaped. The bottom of the water distribution pipe 200 has multiple through-holes 210, which are spaced apart along the outline. Through these through-holes 210, the water distribution pipe 200 can distribute water downwards to the evaporative cooling pad. Because the outline of the water distribution pipe 200 matches the horizontal cross-sectional shape of the evaporative cooling pad, water can be distributed to all positions on the evaporative cooling pad, achieving uniform water distribution.

[0021] In a traditional water distribution pipe 200, water flowing into the pipe can only exit through the drain hole 210, and impurities in the water can easily clog the drain hole 210. In this embodiment, the water pipe structure, through the interconnected design of the inlet pipe 100, the distribution pipe 200, and the drain pipe 300, allows water entering the distribution pipe 200 from the inlet pipe 100 to flow downwards through the drain hole 210 to the evaporative cooling pad. It also carries impurities out of the distribution pipe 200 into the drain pipe 300, finally returning to the water supply structure and settling there. This prevents clogging at the drain hole 210, achieving a self-cleaning function for the water pipe structure, significantly reducing the risk of water supply failures due to clogging, and improving the reliability of the water pipe structure.

[0022] The radial cross-sectional area of ​​the drain pipe 300 is smaller than that of the inlet pipe 100, and the area of ​​the leak hole 210 is smaller than that of the drain pipe 300, so that the water can flow downward at a certain pressure when passing through the leak hole 210, ensuring the water supply to the wet curtain and the continuous cooling effect of the wet curtain.

[0023] Furthermore, the diameter of the drain hole 210 is 2mm-3.5mm, which is similar to the size of existing drain holes 210. The radial cross-sectional area of ​​the drain pipe 300 is 20%-45% of the radial cross-sectional area of ​​the inlet pipe 100. For example, if the diameter of the inlet pipe 100 is 20mm, then the diameter of the drain pipe 300 is 4mm-9mm. Through the above design, it is ensured that water can flow out of the distribution pipe 200 to remove impurities, while also ensuring the water pressure inside the distribution pipe 200, so that the water inside the distribution pipe 200 can flow out evenly from each drain hole 210, improving the uniformity of water distribution.

[0024] Furthermore, the radial cross-sectional area of ​​the outlet of the drain pipe is 28%-50% of the radial cross-sectional area of ​​its inlet. This size of outlet can be achieved by connecting a connector 310 to the drain pipe.

[0025] In one embodiment, since the wet curtain in the air cooler is flat and appears as a strip when viewed from above, the outline of the water distribution pipe 200 is also strip-shaped, i.e., a straight pipe is used. The aforementioned multiple drain holes 210 are set at the bottom of the straight pipe, and the multiple drain holes 210 are spaced apart along the length of the straight pipe. The two ends of the straight pipe are respectively connected to the water inlet pipe 100 and the drain pipe 300.

[0026] In another embodiment, the square evaporative air cooler has air inlets on all four sides and air outlets at the top or bottom. Therefore, evaporative cooling pads are installed at the positions corresponding to the four air inlets inside the air cooler, and the four evaporative cooling pads are connected end-to-end, forming a ring shape when viewed from above. Correspondingly, the water distribution pipe 200 also has a ring-shaped outline, thus distributing water to all four evaporative cooling pads.

[0027] The annular pipe has two connection points: the first position and the second position, which connect to the inlet pipe 100 and the outlet pipe 300, respectively. Two equal-length flow channels exist within the annular pipe, running from the first position to the second position. This design ensures that the resistance encountered by the water flow in both directions is essentially the same, resulting in a highly balanced water pressure distribution throughout the annular pipe. This improves the stability of the pipeline structure during operation and ensures consistent outlet pressure and flow rate at all the leaks 210 at the bottom of the annular pipe, enabling uniform wetting of the lower annular cooling pad and enhancing the cooling effect.

[0028] Preferably, the aforementioned annular pipe is a rectangular or square pipe with a symmetrical structure, and the connection position between the inlet pipe 100 and the distribution pipe 200 (the aforementioned first position) and the connection position between the drain pipe 300 and the distribution pipe 200 (the aforementioned second position) are symmetrically arranged. Preferably, the connection positions between the inlet pipe 100 and the distribution pipe 200 and the drain pipe 300 and the distribution pipe 200 are both located at the corner positions of the distribution pipe 200.

[0029] Specifically, the water distribution pipe 200 includes four straight pipes 220 and four connectors 230. Each straight pipe 220 has multiple drainage holes at its bottom, spaced apart along the length of the pipe. The connectors 230 do not have drainage holes. Adjacent straight pipes 220 are connected by a connector 230, forming a ring pipe. Two connectors 230 are 90° elbows, and the other two are tee joints. The two 90° elbows and two tee joints are alternately arranged, with the two tee joints positioned symmetrically. Each tee joint includes a first connection port 231, a second connection port 232, and a third connection port 233. The first and second connection ports 231 and 232 connect to adjacent straight pipes 220, respectively. The third connection port 233 extends inwards into the water distribution pipe 200 until it reaches the inside of the evaporative cooling pad, allowing the inlet pipe 100 and outlet pipe 300 to connect to the third connection ports 233 of the two tee joints inside the evaporative cooling pad, respectively.

[0030] In this embodiment, the inlet pipe 100, the distribution pipe 200, and the drain pipe 300 are connected to form a whole, which is then fixed to the housing of the air cooler. Specifically, each of the four connectors 230 is provided with a connecting lug 234, and the connecting lug 234 is provided with a through hole 2341. Bolts pass through the through hole 2341 to fix the connector to the housing, that is, to fix the entire water pipe structure inside the housing of the air cooler.

[0031] This embodiment also provides a cooler using the above-described water pipe structure, such as... Figures 6-7As shown, the evaporative cooler includes a housing, an evaporative cooling pad 400 housed within the housing, and a water pipe structure. The water pipe structure adopts the aforementioned water pipe structure for evaporative coolers and is located above the evaporative cooling pad. When the evaporative cooler distributes water to the evaporative cooling pad, a water pump delivers water into the inlet pipe 100. A portion of the water flows through the distribution pipe 200 and out through the drain hole 210 to distribute water to the evaporative cooling pad, while another portion of the water flows out through the drain pipe 300 and returns to the water supply structure.

[0032] 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.
