Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a water tank structure and an evaporative cooling air conditioner using the same. Background Technology

[0002] Evaporative cooling air conditioners use a water circulation system to spray cooling water from a tank onto the evaporator surface, utilizing the principle of water evaporation absorbing heat to cool the air. Simultaneously, a top-mounted axial fan accelerates airflow to enhance heat dissipation efficiency. However, the water tanks of evaporative cooling air conditioners are often square-shaped, formed by bending and welding sheet metal on all four sides. Under long-term full-water pressure, the static pressure of the water causes the side walls to expand outwards, creating concentrated stress, especially at the bends and welds. This continuous expansion force can easily lead to fatigue cracking of the welds, causing water tank leaks or even rupture. This not only increases maintenance costs but may also cause safety accidents such as short circuits. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a water tank structure and an evaporative cooling air conditioner using the same structure. This solves the problem that in existing evaporative cooling air conditioners, the water tank is prone to fatigue cracking of the welds under long-term full-water pressure conditions, leading to water tank leakage or even rupture.

[0004] On the one hand, according to the embodiments of this utility model, the present utility model adopts the following technical solution:

[0005] A water tank structure includes a tank body with a water outlet pipe extending through its interior. The water tank structure also includes at least one support frame disposed on the inner side of the tank body. The support frame includes two first reinforcing plates disposed along the length direction of the tank body and a plurality of second reinforcing plates disposed along the width direction of the tank body. The two first reinforcing plates are respectively disposed on two opposite inner sides of the tank body, and the plurality of second reinforcing plates are connected between the two first reinforcing plates.

[0006] Preferably, the bottom surface of the second reinforcing plate has a water-permeable notch.

[0007] Preferably, the bottom of the box is provided with a drain pipe, the end of which extends into the interior of the box.

[0008] Preferably, a water supply pipe is provided on the side of the box, and the end of the water supply pipe extends into the interior of the box.

[0009] Preferably, a float valve is provided on the inner side of the tank, and the float valve is connected to the end of the water supply pipe.

[0010] Preferably, the side of the tank is also provided with an overflow pipe, the end of which extends into the interior of the tank, and the distance between the end of the overflow pipe and the bottom of the tank is greater than the distance between the end of the water supply pipe and the bottom of the tank.

[0011] Preferably, the water tank structure also includes a filter cover, which is fastened to the inside of the tank and corresponds to the end of the water outlet pipe.

[0012] Preferably, the water tank structure also includes a limiting frame, which is installed on the inner bottom surface of the tank body. A magnesium rod is inserted through the side of the tank body, and the limiting frame is provided with two limiting blocks. The magnesium rod is engaged between the two limiting blocks.

[0013] Preferably, the limiting frame is U-shaped and is snapped into one of the second reinforcing plates.

[0014] On the other hand, according to the embodiments of this utility model, the present utility model also adopts the following technical solutions:

[0015] An evaporative cooling air conditioner includes a water pump and a spray system connected to the water pump, and also includes a water tank structure, with the water pump connected to an outlet pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Under the support frame, multiple second reinforcing plates arranged along the width of the tank are connected to two first reinforcing plates arranged along the length of the tank, forming a crisscrossing internal support frame structure to connect the various inner sides of the tank. This enhances the rigidity of the tank in the length direction and also distributes the stress in the width direction through the second reinforcing plates, achieving bidirectional support. This makes the overall stress on the tank more uniform and avoids stress concentration in weak areas such as bending, butt-joint welds, thereby significantly reducing the risk of water tank leakage and rupture and improving the safety and reliability of equipment operation.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0034] The bend and butt weld of a traditional water tank is the weakest part of the structure. When the water tank is full, the static pressure of the water acts on the side wall of the tank, which easily causes the sheet metal side wall to bulge outward. Long-term tensile stress can easily cause fatigue cracks. Based on this, this utility model proposes a water tank structure, including a tank body 1. The tank body 1 is provided with a water outlet pipe 7 that penetrates into its interior. The water tank structure also includes at least one support frame located inside the tank body 1. The support frame includes two first reinforcing plates 2 arranged along the length direction of the tank body 1 and multiple second reinforcing plates 3 arranged along the width direction of the tank body 1. The two first reinforcing plates 2 are respectively located on two opposite inner sides of the tank body 1, and the multiple second reinforcing plates 3 are connected between the two first reinforcing plates 2.

[0035] In the embodiments of this utility model, such as Figure 2 As shown, multiple second reinforcing plates 3 arranged along the width direction of the housing 1 are connected to two first reinforcing plates 2 arranged along the length direction of the housing 1, forming a crisscrossing internal support frame structure to connect the various inner sides of the housing 1. This enhances the rigidity of the housing 1 in the length direction and also distributes the stress in the width direction through the second reinforcing plates 3, achieving bidirectional support and bearing most of the water pressure load. This significantly reduces the tensile stress on the welds of the side walls of the housing 1, making the overall stress on the housing 1 more uniform and avoiding stress concentration in weak areas such as bending and butt welds. This greatly reduces the risk of leakage and cracking of the housing 1, and improves the safety and reliability of equipment operation. When using a single support frame, the support frame is preferably installed in the middle of the housing 1. To further ensure the stability of the housing 1 structure, it is preferable to use two support frames, installed at the top and opening of the housing 1 respectively.

[0036] Specifically, the bottom surface of the second reinforcing plate 3 has a water passage notch 301. Since the support frame at the bottom is attached to the inner bottom surface of the box 1, it may hinder the free flow of cooling water at the bottom of the box 1. Under the action of the water passage notch 301, an effective flow channel is provided for the water at the bottom of the box 1, ensuring that the water pump draws water evenly and stably.

[0037] Specifically, the bottom of the housing 1 is provided with a drain pipe 6, the end of which extends into the interior of the housing 1. By providing a drain pipe 6 that extends into the interior at the bottom of the housing 1, the residual cooling water inside the housing 1 can be completely drained during shutdown maintenance, thus avoiding problems such as corrosion and microbial growth caused by water accumulation.

[0038] Meanwhile, a water supply pipe 4 is provided on the side of the housing 1. The end of the water supply pipe 4 extends into the interior of the housing 1. As the air conditioner consumes cooling water due to continuous evaporation during operation, the water level will gradually drop. The water supply pipe 4 is connected to an external water source, and water is automatically replenished when the water level is lower than the set value, ensuring that the water tank 1 always maintains an effective water level, and ensuring that the water pump can draw water normally and the evaporator can spray water evenly.

[0039] Furthermore, to facilitate automatic water replenishment and shut-off control, a float valve 401 is installed inside the tank 1. The float valve 401 is connected to the end of the water replenishment pipe 4. The float valve 401 is a hardware material in the prior art, with a specification model of Q21F-40P. The float valve 401 drives the valve core to open and close by the float rising and falling with the water level. When the water level in the tank 1 drops to the set lower limit, the float falls and automatically opens the water supply channel of the water replenishment pipe 4. When the water level rises back to the set upper limit, the float rises and automatically shuts off the water replenishment. Fully automatic water replenishment can be achieved without external power supply or electronic controller.

[0040] Specifically, the side of the tank 1 is also provided with an overflow pipe 5. The end of the overflow pipe 5 extends into the interior of the tank 1, and the distance between the end of the overflow pipe 5 and the bottom of the tank 1 is greater than the distance between the end of the water supply pipe 4 and the bottom of the tank 1. The overflow pipe 5 serves as a safe discharge channel for the highest water level. When the float valve 401 fails, the water supply is out of control, or the external water pressure rises abnormally, the water level will rise to the height of the overflow pipe 5 inlet and automatically overflow, preventing the tank 1 from being completely overflowed. In actual use, the overflow pipe 5 can be connected to an external collection container.

[0041] Specifically, the water tank structure also includes a filter cover 701. The filter cover 701 is fastened to the inside of the housing 1 and corresponds to the end of the water outlet pipe 7. During long-term operation of the air conditioner, scale, dust or external particles may accumulate inside the housing 1. By placing the filter cover 701 at the water inlet end of the water outlet pipe 7, suspended impurities can be effectively intercepted and prevented from entering the water pump, pipes and evaporator water spray system with the cooling water, thus avoiding nozzle blockage or affecting the heat exchange of the evaporator magnetic fins.

[0042] Specifically, such as Figure 2 and Figure 3 As shown, the water tank structure also includes a limiting frame 9, which is located on the inner bottom surface of the tank body 1. A magnesium rod 8 is inserted through the side of the tank body 1, and the limiting frame 9 is provided with two limiting blocks 901. The magnesium rod 8 is snapped between the two limiting blocks 901. To prevent the formation of scale in the tank body 1, the magnesium rod 8 can adsorb calcium and magnesium ions in the water through a chemical reaction, converting the scale into soluble substances or tiny particles, reducing the probability of scale adhering to the surface of the evaporator fins, thereby improving the heat exchange efficiency of the evaporator. At the same time, the magnesium rod 8 will gradually dissolve during use. If it is not fixed firmly, it may be displaced or even fall off due to water flow disturbance or vibration. By setting the limiting frame 9 at the bottom of the tank body 1 and configuring two elastic limiting blocks 901 to snap and fix the magnesium rod 8, it is ensured that it is always in the preset position.

[0043] Moreover, the limiting frame 9 is U-shaped and is snapped onto one of the second reinforcing plates 3. In order to avoid drilling holes in the inner bottom surface of the box 1 again, the limiting frame 9 also adopts an elastic structure, which can be snapped onto the second reinforcing plate 3 by elastic clamping to achieve quick installation.

[0044] like Figure 1 As shown, this utility model embodiment also proposes an evaporative cooling air conditioner, including a water pump 10 and a spray system 11 connected to the water pump 10, and also includes the above-mentioned water tank structure. The water pump 10 is connected to the water outlet pipe 7. The specific structure of the water tank structure is as described in the above embodiment. Since this evaporative cooling air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
