[0026] Reference Figures 1 to 3 The embodiment of the present application provides an air cooler, specifically including a frame 100, the frame 100 is divided into a first layer and a second layer, the side of the first layer is blocked, a plurality of cooling fans 300 are arranged in the first layer, the side of the second layer is open, a plurality of groups of heat exchange tube bundles 200 are arranged in the second layer, a plurality of pipe fittings 250 for cooling medium flow and heat exchange are arranged in the heat exchange tube bundles 200, an inlet pipe 210 for cooling medium distribution and an outlet pipe 220 for cooling medium collection are provided at the end of the frame 100, a part of the pipe fittings 250 is connected to the inlet pipe 210, a part of the pipe fittings 250 is connected to the outlet pipe 220, the pipe fittings 250 extend along the length direction of the frame 100, and there is a gap between adjacent pipe fittings 250.

[0027] Compared with the existing air cooler, the air cooler of the present application simplifies the setting of the frame 100 and divides the frame 100 into a first layer and a second layer. The first layer is located above the second layer. The side of the first layer is enclosed and a plurality of cooling fans 300 are arranged inside. The heat exchange tube bundle 200 arranged on the second layer is connected to the internal cooling system pipeline through the inlet pipe 210 and the outlet pipe 220. The heat of the cooling medium in the internal cooling system is transferred to the external environment through the pipe fittings 250 of the heat exchange tube bundle 200. The extension of the pipe fittings 250 along the length direction can increase the contact area between the pipe fittings 250 and the external air. The gaps between adjacent pipe fittings 250 can avoid heat accumulation and local overheating, and are also conducive to air circulation and thus drive heat dissipation.

[0028] When the cooling fan 300 is started, since the side of the first layer is closed, the first layer is equivalent to an air collecting port, which can effectively drive the air flow between the pipes 250 in the second layer. Specifically, the air flow direction of the air cooler is as follows: Figure 5 As shown, cold air enters through the side, flows through the heat exchange tube bundle 200, forms hot air, and finally diffuses into the atmosphere through the cooling fan 300, further improving the heat dissipation effect. Compared with the previous design of repeatedly bending the pipe 250 to increase the contact area between the pipe 250 and the air, the present application solves the problem of inconvenient air circulation between the pipes 250, making the straight-designed pipe 250 easier to manufacture and easier to lay out, making the entire air cooler more compact and reasonable, and making subsequent maintenance more convenient.

[0029] Among them, Figure 4 As shown, the inlet pipe 210 is provided with an inlet port for docking with the internal cooling system pipeline. The inlet pipe 210 is provided with a plurality of parallel first branch pipes 211 according to the number of the heat exchange tube bundles 200. The cooling medium transported from the internal cooling system pipeline is distributed to some pipe fittings 250 on the heat exchange tube bundle 200 through the first branch pipes 211 for heat dissipation.

[0030] like Figure 4 As shown, the outflow pipe 220 is also provided with an outlet for docking with the internal cooling system pipeline. The outflow pipe 220 is provided with an equal number of second branch pipes 221 according to the number of the heat exchange tube bundles 200. The cooling medium that has completed the heat exchange through the second branch pipes 221 and the pipe fittings 250 is collected at the outlet and transported back to the internal cooling system pipeline.

[0031] In the embodiment of the present application, one end of the pipe fitting 250 extends from one end of the frame 100 toward the other end of the frame 100, and except for the pipe fitting 250 connected to the outflow pipe 220 or the inlet pipe 210, the two ends of the remaining pipe fittings 250 are respectively connected to the ends of different pipe fittings 250. Of course, the other end of the pipe fitting 250 connected to the outflow pipe 220 or the inlet pipe 210 is also connected to other pipe fittings 250, so that several pipe fittings 250 form an S-shaped flow path, which increases the heat exchange time of the cooling medium and greatly improves the heat exchange effect.

[0032] In the present application embodiment, Figure 1 and Figure 2 As shown, the frame 100 is in the shape of a cuboid, and the frame 100 includes a first rectangular frame, a second rectangular frame, and a plurality of pillars 101. The corners of the first rectangular frame and the second rectangular frame are connected by the pillars 101 to form a rectangular frame 100. Specifically, the first rectangular frame includes two first connecting members 102 and two second connecting members 103. The first connecting members 102 constitute the long side of the first rectangular frame, and the second connecting members 103 constitute the short side of the first rectangular frame. A third connecting member 104 is also provided between the two first connecting members 102 to enhance the structural stability. The second rectangular frame includes two fourth connecting members 107 and two fifth connecting members 108. The fourth connecting members 107 constitute the short side of the second rectangular frame, and the fifth connecting members 108 constitute the long side of the second rectangular frame. Figure 6 As shown, a reinforced middle column 110 is arranged between the two fourth connecting members 107, and a plurality of stabilizing columns 130 are arranged between the reinforced middle column 110 and the fifth connecting member 108 to ensure that the entire second rectangular frame can bear a larger load and is not easily deformed. A baffle 140 is also arranged at the hollow part of the second rectangular frame to prevent dust.

[0033] In some embodiments, a third rectangular frame is disposed between the first rectangular frame and the second rectangular frame, and a fence 106 is disposed on the side between the third rectangular frame and the first rectangular frame to separate the frame 100 into a first layer and a second layer, and the cooling fan 300 is fixed to the third rectangular frame. The third rectangular frame includes two sixth connecting members 105 and two seventh connecting members 109, the sixth connecting members 105 constitute the short side of the third rectangular frame, and the seventh connecting member 109 constitutes the long side of the third rectangular frame. To facilitate the fixing of the cooling fan 300, a cross is disposed between the two seventh connecting members 109.

[0034] In some embodiments, a larger side array between the third rectangular frame and the second rectangular frame is provided with reinforcing columns 120 to improve the structural rigidity and bearing capacity of the entire frame 100 .

[0035] In the present application embodiment, Figure 2 As shown, the heat exchange tube bundle 200 includes a mounting frame 230 for fixing the tube 250. The mounting frame 230 is used to fix the tube 250 at a certain gap, and can also prevent the tube 250 from bending and affecting the flow of the cooling medium. Furthermore, a reinforcing rib 240 is provided between the mounting frame 230 and the reinforcing column 120. The provision of the reinforcing rib 240 improves the structural strength of the frame 100, making the connection of the frame 100 more stable.

[0036] In the preferred embodiment of the present application, Figure 4 and Figure 5 As shown, at least two groups of heat exchange tube bundles 200 are provided, and the two groups of heat exchange tube bundles 200 are arranged in a V shape. Specifically, the top of the heat exchange tube bundle 200 is against the side of the frame 100 close to the first layer, and the tops of the two groups of heat exchange tube bundles 200 are gathered at the lower center of the frame 100. A stable triangle is formed between the heat exchange tube bundle 200, the second rectangular frame and the support, so that the structure of the entire frame 100 is further strengthened.

[0037] In some embodiments, the diameter of the tube 250 may be 25.4 mm, 19.05 mm, or 15.88 mm, wherein the diameter of the tube 250 is preferably 19.05 mm.

[0038] In some embodiments, the distance between the surfaces of two adjacent pipes 250 is set to L, wherein 1 mm ≤ L ≤ 5 mm. Specifically, L is preferably 2 mm.

[0039] The pipe fitting 250 of the present application can be made of stainless steel or copper. Specifically, the pipe fitting 250 is easily made of stainless steel in a working environment with high environmental corrosion, and is easily made of copper in a working environment with high heat exchange requirements.

[0040] The air cooler of the present application adopts a container modular design. Two independent external cooling systems are set on the same frame 100 through reasonable design with the main circulation device. Each functional device is designed according to the optimal performance point to minimize the various sizes of the equipment to achieve a highly integrated design. The frame 100 is set to a size of 20 feet. Multiple 20-foot air coolers can be connected in parallel and regulated by regulating valves to solve the problem of uneven flow distribution, and the flow of the independent system can be regulated by the flow control valve. The regulation effect is fed back to the control system through the flow sensor on the system.

[0041] By connecting pipes in parallel, the large cooling capacity requirements of various working conditions can be met. The heat exchange capacity of a single set of equipment can reach 600kW. If the customer's heat exchange capacity requirement is 4800kW, 6 air coolers can be connected in parallel to meet customer requirements.

[0042] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
