[0040] In the following, various embodiments of the present invention will be described more fully. The present invention may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present invention to the specific embodiments disclosed herein, but rather the present invention should be understood to cover all adjustments, equivalents and / or alternatives that fall within the spirit and scope of the various embodiments of the present invention.

[0041] Hereinafter, the terms "include" or "may include" used in various embodiments of the present invention indicate the presence of disclosed functions, operations or elements, and do not limit the addition of one or more functions, operations or elements. In addition, as used in various embodiments of the present invention, the terms "include", "have" and their cognates are intended only to indicate specific features, numbers, steps, operations, elements, components or combinations of the foregoing, and should not be understood as first excluding the presence of one or more other features, numbers, steps, operations, elements, components or combinations of the foregoing or the possibility of adding one or more features, numbers, steps, operations, elements, components or combinations of the foregoing.

[0042] like Figure 1-7 As shown, the utility model provides an air film structure with a cooling function, comprising an inflatable film layer 1, an insulating layer 2 and an air supply device 3, an air film space 10 is formed between the inflatable film layer 1 and the ground, and the insulating layer 2 is arranged on the inflatable film layer 1; the insulating layer 2 comprises a plurality of air fin tube segments 2122, and the plurality of air fin tube segments 2122 are arranged in sequence on the inflatable film layer 1; one or at least two connected air fin tube segments 2122 constitute an air duct, so that a plurality of air ducts are formed on the insulating layer; and each air duct is provided with an air inlet 23 and an air outlet 24, the air inlet 24 is connected to the air supply device 3, and the air duct is used for connecting the cold air of the air supply device 3 to mix the cold air with the heat of the inflatable film layer 1 to cool the air film space 10; the air outlet 24 is used to discharge the cold air and heat mixed in the air duct to the outside. The utility model mixes the cold air with the heat of the inflatable film layer 1 to cool the air film space 10 through the cooperation between the multiple air ducts on the insulation layer 2, the air inlets 23, the air outlets 24 and the air supply device 3 on the air ducts, thereby improving the safety and reliability of the air film structure.

[0043] Specifically, the inflatable membrane layer 1 is arranged on a structural foundation 9 to form an air membrane space 10 between the inflatable membrane layer 1 and the ground.

[0044] In one embodiment, the multiple air ducts include multiple first air ducts 21, multiple air fin tube segments 2122 are arranged side by side on the inflatable membrane layer 1, at least two adjacent air fin tube segments 2122 are connected end to end to form the first air duct 21, the air inlet 23 is located at the head end of the first exhaust fin tube segment 2122, and the air outlet 24 is located at the tail end of the last exhaust fin tube segment 2122. Cold air is delivered to at least two air fin tube segments 2122 through the first air duct 21, reducing the setting of the air inlet on the insulation layer 2, thereby reducing the number of pipeline connections between the air fin tube segments 2122 and the air supply device 3, while achieving a good cooling effect on the air membrane space 10, and also simplifying the overall structure of the air membrane. Among them, a vent 21221 is provided between every two adjacent air fin tube segments 2122, and the adjacent air fin tube segments 2122 are connected through the vent 21221.

[0045] In another embodiment, the multiple air ducts include multiple second air ducts 22, and the multiple air fin tube segments 2122 are arranged side by side and independent of each other. A single air fin tube segment 2122 forms a second air duct 22, and each air fin tube segment 2122 corresponds to at least one air inlet 23 and at least one air outlet 24. Cold air is delivered to the single air fin tube segment 2122 through the second air duct 22, thereby enhancing the rate of cold air delivery and greatly improving the cooling effect, thereby improving the safety and reliability of the air membrane structure.

[0046] In other embodiments, the plurality of air ducts include at least one first air duct 21 and at least one second air duct 22, and the plurality of air fin tube segments 2122 are arranged side by side on the inflatable membrane layer 1, and at least two adjacent air fin tube segments 2122 are connected end to end to form a first air duct 21; a single air fin tube segment 2122 forms a second air duct 22; and the first air duct 21 and the second air duct 22 are arranged alternately. Through the mutual cooperation of the first air duct 21 and the second air duct 22, a good cooling effect is achieved on the air membrane space 10, and the pipeline connection between the air supply device 3 and the air fin tube segment 2122 is reduced to a certain extent.

[0047] Among them, the number of the air fin sections 2122 of each first air duct 21 is not greater than 4.

[0048] The air inlet 23 of the second air duct 22 is located at both ends of the air fin tube section 2122, and the air outlet 24 of the second air duct 22 is located in the middle of the air fin tube section 2122;

[0049] Alternatively, the air inlet 23 of the second air duct 22 is located at one end of the air fin tube section 2122 , and the air outlet 24 of the second air duct 22 is located at the other end of the air fin tube section 2122 .

[0050] like Figure 1-11As shown, the air film structure with cooling function of the utility model also includes a controller 4, and at least one exhaust port 24 is provided with a pressure sensor 5, a temperature sensor 6 and an exhaust valve 7. The pressure sensor 5 is used to detect the air pressure in the air duct, and the temperature sensor 6 is used to detect the temperature in the air duct. The controller 4 is electrically connected to the pressure sensor 5, the temperature sensor 6 and the exhaust valve 7 respectively, and is used to adjust the exhaust valve 7 when the air pressure exceeds the preset air pressure range or the temperature exceeds the preset temperature range. The pressure sensor 5 and the temperature sensor 6 detect the environment in the air duct, and when the air pressure exceeds the preset air pressure range or the temperature exceeds the preset temperature range, the exhaust valve 7 is timely controlled by the controller 4 to timely adjust the exhaust port 24 to open or adjust the opening degree of the exhaust port 24, so that the hot air in the air duct is discharged to the outside in time, so as to replace the wind in the air duct, thereby reducing the temperature of the air film space 10, and thus improving the safety and reliability of the device.

[0051] The exhaust valve 7 includes a regulating valve for adjusting the opening.

[0052] like Figure 3 As shown, the inflatable film layer 1 includes an inner film layer 11 and an outer film layer 12, and the heat insulation layer 2 is located between the inner film layer 11 and the outer film layer 12, and the projection area of ​​the heat insulation layer 2 on the outer film layer 12 accounts for 0.5-1 of the area of ​​the outer film layer 12. By increasing the contact area between the heat insulation layer 2 and the outer film layer 12, the heat insulation layer 2 can better cool the air film structure, thereby achieving a better cooling effect.

[0053] Preferably, the projection area of ​​the heat insulation layer 2 on the outer film layer 12 accounts for 1 of the area of ​​the outer film layer 12 .

[0054] Among them, the projection of the thermal insulation layer 2 on the outer film layer 12 is located in the middle area of ​​the outer film layer 12. Because the sun usually shines on the top of the air film structure, the heat received by the top will be higher than the heat received by the edge area. Therefore, locating the projection of the thermal insulation layer 2 on the outer film layer 12 in the middle area of ​​the outer film layer 12 can specifically cool down the area with high heat.

[0055] The heat insulation layer 2 and the inner film layer 11 can be integrally formed or detachably connected. Fig.12 As shown, the thermal insulation layer 2 and the inner film layer 11 are detachably connected, as shown in FIG. Fig.13 As shown, the heat insulation layer 2 and the inner film layer 11 are integrally formed.

At this time, cold air enters from the two ends of the air fin tube section 2122, mixes with the heat of the inflatable membrane layer 1, and then the mixed air and heat are discharged from the middle of the air fin tube section 2122.
