[0002] In the fields of construction, power, and municipal engineering, large commercial air conditioning equipment such as multi-split systems and air-cooled modular units often suffer from excessively high intake air temperatures due to high-temperature environments. This reduces the equipment's heat exchange efficiency, increases energy consumption, and may even trigger overheat protection shutdowns. Currently, natural ventilation is the primary means of heat dissipation.

[0003] The present invention aims to provide a low-cost, low-energy-consumption external gas cooling structure to achieve efficient cooling of the air intake of equipment such as multi-split air conditioners and air-cooled modular units. Utility Model Content

[0004] This utility model provides an external gas cooling structure to solve the problems in the prior art.

[0005] The present invention adopts the following technical solution: an external gas cooling structure, comprising: a water supply device having at least a receiving cavity for containing liquid and a plurality of water-permeable holes located at the bottom of the receiving cavity; a water receiving tank having an open top and located directly below the water supply device; a seepage structure fixedly disposed between the water supply device and the water receiving tank, the seepage structure comprising at least an outer frame and a filling layer fixed within the outer frame, the filling layer being formed as a multi-gap or multi-porous structure; the liquid in the receiving cavity can flow evenly through the plurality of water-permeable holes into the top of the filling layer and permeate through the filling layer into the water receiving tank; and a return device for transferring the liquid in the water receiving tank to the receiving cavity.

[0006] Preferably, the filling layer is configured as a rectangular block structure, the outer frame having at least two side plates, two upper right-angle edging strips, and two lower right-angle edging strips; the two side plates are arranged opposite each other on the left and right sides of the filling layer, and each side plate has a vertically arranged inner groove on its inner side, the left and right ends of the filling layer being respectively embedded in the two inner grooves; the two upper right-angle edging strips are respectively attached to the front and rear corner edges of the upper end of the filling layer, and both upper right-angle edging strips are fixedly connected to the two side plates; the two lower right-angle edging strips are respectively attached to the front and rear corner edges of the lower end of the filling layer, and both lower right-angle edging strips are fixedly connected to the two side plates.

[0007] Preferably, at least a portion of the structure of each of the two side plates extends above the two upper right-angle edging strips; the water supply device is located above the two upper right-angle edging strips and is fixedly connected to the two side plates.

[0008] Preferably, a water-immersing layer is provided between the water supply device and the filling layer, and a number of water-permeable holes are all directly facing the upper end of the water-immersing layer. The lower end of the water-immersing layer is located between two upper right-angled edge strips and is placed flat on the upper end of the filling layer; the water-immersing layer has water absorption characteristics.

[0009] Preferably, a bracket is placed inside the water receiving tank, and the outer frame is installed on the upper end of the bracket so that the filling layer is suspended relative to the water receiving tank.

[0010] Preferably, the reflux device includes: a water pump, fixedly installed in the water receiving tank; an inlet pipe, one end of which is connected to the inlet end of the water pump, and the other end of which is located in the water receiving tank; a drain pipe, one end of which is connected to the outlet end of the water pump, and the water supply device is connected to a connecting pipe that communicates with the receiving cavity, and the other end of the drain pipe is connected to the connecting pipe.

[0011] Preferably, the filling layer is provided with a longitudinally extending clearance channel, and the drain pipe is located within the clearance channel.

[0012] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: Firstly, the liquid inside the containment cavity drips evenly through the permeable holes at the bottom to the permeable structure below. Because the filling layer of the permeable structure has multiple gaps or pores, after absorbing the liquid, it distributes the moisture throughout the filling layer through its own permeability, forming a moist heat exchange surface, thereby cooling the hot air passing through the filling layer. The design of the permeable holes ensures that the water in the containment cavity flows into the permeable structure in a dripping manner, thus minimizing noise to some extent.

[0013] Secondly, when this cooling structure is used to cool external equipment, multiple cooling structures are wrapped around the air intake side of the external equipment. When the external equipment is running, the hot air drawn in from the environment at its air intake end will first pass through the filling layer area of ​​the cooling structure. The moisture in the filling layer comes into contact with the flowing hot air, evaporates, and absorbs heat from the air, thus lowering the air temperature. Attached Figure Description

Detailed Implementation

[0016] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0017] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1 to 8 As shown, this utility model embodiment provides an external gas cooling structure, including a water supply device 1, a water receiving tank 2, a water seepage structure 3, and a return flow device 4.

[0019] The water supply device 1 has at least a receiving cavity 11 for containing liquid (generally water) and a plurality of water-permeable holes 12 located at the bottom of the receiving cavity 11. Specifically, the water supply device 1 is configured as a water tank, the top of which has a water inlet trough 14, and an openable door 15 is installed at the water inlet trough 14. Water can be injected into the receiving cavity 11 by opening and closing the door 15. It should be noted that a water level sensor can also be installed in the water tank, and an automatic water supply circuit can be connected to the water tank. When the sensor detects that the water level in the tank has reached the lower limit threshold, water can be supplied to the water tank by the automatic water supply circuit.

[0020] The water receiving tank 2 has an opening at the top and is located directly below the water supply device 1; the seepage structure 3 is fixedly installed between the water supply device 1 and the water receiving tank 2. The seepage structure 3 includes at least an outer frame 31 and a filling layer 32 fixed inside the outer frame 31. The filling layer 32 is formed as a multi-gap or porous structure; the liquid in the receiving cavity 11 can flow evenly into the top of the filling layer 32 through several water-permeable holes 12 and then permeate through the filling layer 32 into the water receiving tank 2. At the same time, the multi-gap or porous structure of the filling layer 32 also allows airflow to pass through; the return device 4 is used to transfer the liquid in the water receiving tank 2 into the receiving cavity 11.

[0021] In this embodiment, the external gas cooling structure reduces the air temperature at the air inlet 71 of the external device 7 (such as a multi-split air conditioner, air-cooled modular air conditioner, etc.) by combining liquid evaporation heat absorption with air heat exchange. The specific working process of the external gas cooling structure is as follows: Liquid (usually water) within the receiving cavity 11 drips evenly through the permeable holes 12 at the bottom to the lower permeable structure 3. After absorbing the liquid, the filling layer 32 of the permeable structure 3 distributes the moisture throughout its porous structure, forming a moist heat exchange surface. When the external equipment 7 is running, the hot air drawn in from the environment at its air inlet first passes through the filling layer 32 area of ​​the cooling structure. The moisture in the filling layer 32 comes into contact with the flowing hot air, evaporates, and absorbs heat from the air, lowering the air temperature. The design of the permeable holes 12 ensures that the water in the receiving cavity 11 flows into the permeable structure 3 in a dripping manner, mitigating noise to some extent. Simultaneously, the permeable characteristics of the porous structure of the filling layer 32 ensure unobstructed airflow. In practical applications, the filling layer 32 uses existing water curtain paper, made from Jiamusi and Huatai long-fiber pulp paper, which features high water absorption, high water resistance, long service life, high hardness, and mildew resistance. The water curtain paper has a honeycomb structure to ensure good air permeability. It should be noted that the filling layer is not limited to paper materials; modified PVC or plastic materials are also acceptable. The main emphasis of the filling layer is on a porous and interstitial structure, which allows water to cover its surface while ensuring that airflow can pass through effectively.

[0022] Liquid that has not evaporated after passing through the filling layer 32 drips down into the water receiving tank 2 below, thus achieving liquid recovery. The return device 4 transports the liquid in the water receiving tank 2 back to the receiving cavity 11 of the water supply device 1, forming a closed-loop circulation and reducing water consumption.

[0023] In practical applications, multiple cooling structures can be arranged in a specific manner (e.g., Figure 8The U-shaped structure (the arrow in the diagram indicates the gas flow direction) wraps around the air inlet of the external device 7, increasing the air contact area. The gaps in the cooling structure and the space between it and the external device 7 are sealed with sheet metal or plastic film to ensure that hot air is forced to flow through the filling layer 32, improving cooling efficiency. Compared with traditional spray cooling or air conditioning-assisted cooling systems, this external gas cooling structure does not require complex electronic control components, is low in cost, and is easy to install.

[0024] In other practical application scenarios, where multi-split air conditioners, air-cooled modular units, and other air conditioning equipment are placed directly inside the equipment room rather than exposed to the external environment, the cooling structure can be installed inside the windows of the equipment room. This ensures that the gas flowing into the equipment room from the external environment is low-temperature gas.

[0025] In some practical applications, the assembly method of the filling layer 32 and the outer frame 31 can be as follows: (Refer to...) Figure 3 , Figure 2 and Figure 7 As shown, the filling layer 32 is configured as a rectangular block structure. The outer frame 31 has at least two side plates 311, two upper right-angle edging strips 312, and two lower right-angle edging strips 313. The two side plates 311 are arranged opposite each other on the left and right sides of the filling layer 32, and each side plate 311 has a vertically arranged inner groove 3111 on its inner side. The left and right ends of the filling layer 32 are respectively embedded in the two inner grooves 3111. The two upper right-angle edging strips 312 are respectively attached to the front and rear corner edges of the upper end of the filling layer 32, and the two upper right-angle edging strips 312 are fixedly connected to the two side plates 311. The two lower right-angle edging strips 313 are respectively attached to the front and rear corner edges of the lower end of the filling layer 32, and the two lower right-angle edging strips 313 are fixedly connected to the two side plates 311.

[0026] Specifically, at least a portion of the structure of each of the two side plates 311 extends above the two upper right-angled edge strips 312; the water supply device 1 is located above the two upper right-angled edge strips 312 and is fixedly connected to the two side plates 311.

[0027] In this embodiment, the two side plates 311 of the outer frame 31 are positioned opposite each other on the left and right sides of the filling layer 32, with the left and right ends of the filling layer 32 directly embedded in the inner grooves 3111. The depth of the inner grooves 3111 can be designed according to the thickness of the filling layer 32 to ensure a tight fit between the filling layer 32 and the side plates 311. The upper right-angle edging strip 312 is attached to the front and rear corner edges of the upper end of the filling layer 32 and is fixedly connected to the two side plates 311 by bolts. The lower right-angle edging strip 313 is attached to the front and rear corner edges of the lower end of the filling layer 32 and is also fixedly connected to the two side plates 311. The upper and lower right-angle edging strips 312 and 313 wrap around the corners of the upper and lower ends of the filling layer 32, preventing damage to the filling layer 32 due to collisions during transportation or assembly, while also enhancing the overall structural rigidity and load-bearing capacity.

[0028] The two side plates 311 extend upwards to the upper side of the two upper right-angle edging strips 312, and the water supply device 1 is fixed to the extended section of the side plates 311 by bolts. The water supply device 1 is integrated into the installation by utilizing the extended structure of the side plates 311, without the need for additional supports; at the same time, the vertical distance between the water supply device 1 and the filling layer 32 is controlled by the height of the side plates 311, ensuring that the water flow from the permeable holes 12 drips evenly onto the top of the filling layer 32.

[0029] In other practical applications, based on any of the above implementation methods: refer to Figures 4 to 6 As shown, a water-immersing layer 5 is also provided between the water supply device 1 and the filling layer 32. Several water-permeable holes 12 are all directly facing the upper end of the water-immersing layer 5. The lower end of the water-immersing layer 5 is located between two upper right-angle binding strips 312 and is placed flat on the upper end of the filling layer 32. The water-immersing layer 5 has water absorption characteristics and can also be made of water curtain paper.

[0030] Several permeable holes 12 are positioned directly above the water-immersing layer 5. When individual permeable holes 12 become clogged with impurities (such as scale or dust in the water), the water-immersing layer 5 can absorb and diffuse water laterally, evenly distributing the liquid flowing from the unblocked permeable holes 12 across the entire surface of the water-immersing layer 5. This prevents the cooling efficiency of the filling layer 32 from decreasing due to localized water shortage. The lower end of the water-immersing layer 5 rests flat on top of the filling layer 32 and is located between the two upper right-angled edge strips 312. After absorbing water, the water-immersing layer 5 uses capillary action and gravity to evenly transfer the liquid to the entire upper surface of the filling layer 32 below, ensuring that the filling layer 32 remains moist from the edge to the center.

[0031] Furthermore, if liquid drips directly from the permeable hole 12 onto the filling layer 32, the material of the filling layer 32 may be damaged due to the impact. The water-immersing layer 5 can absorb the impact of the water flow and slowly permeate the liquid into the filling layer 32 through planar contact, thus extending the service life of the filling layer 32.

[0032] In some practical applications, refer to Figures 3 to 4As shown, a bracket 6 is placed inside the water receiving tank 2, and the outer frame 31 is installed on the upper end of the bracket 6, so that the filling layer 32 is suspended relative to the water receiving tank 2. After the bracket 6 is suspended, the liquid in the water receiving tank 2 can converge to the lowest point at the bottom under the action of gravity, and the liquid in the water receiving tank 2 is not blocked by the filling layer 32, which facilitates the efficient collection of liquid by the return device 4.

[0033] Specifically, the return flow device 4 includes: a water pump 41 fixedly installed in the water receiving tank 2; an inlet pipe 42, one end of which is connected to the inlet end of the water pump 41, and the other end of which is located in the water receiving tank 2; a drain pipe 43, one end of which is connected to the outlet end of the water pump 41; a connecting pipe 13 connected to the receiving cavity 11 is attached to the water supply device 1; and the other end of the drain pipe 43 is connected to the connecting pipe 13. The water pump 41 transports the water accumulated in the water receiving tank 2 to the receiving cavity 11.

[0034] Furthermore, the filling layer 32 is provided with a longitudinally extending clearance channel 321, within which the drain pipe 43 is located. The clearance channel 321 (such as a strip-shaped groove along the length direction) is used to accommodate the drain pipe 43, ensuring that the drain pipe 43 can be arranged longitudinally along the filling layer 32 without protruding from the surface of the filling layer 32, avoiding structural interference with components such as the outer frame 31, water supply device 1, or water receiving tank 2, and the absence of external leakage of the drain pipe 43 also improves the overall aesthetics.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
