[0026] In most areas, after the onset of summer, the high ambient temperature and the large amount of heat dissipated by the air-cooling system cause the local ambient temperature on the air-cooled island to far exceed the ambient temperature. Some electrical control boxes, especially those with frequency converters, generate a large amount of heat during operation, which further increases the temperature inside the electrical control box to be higher than the local ambient temperature on the air-cooled island. However, electrical control equipment such as PLCs, touch screens, and frequency converters require a relatively cool ambient temperature to operate normally. Once the ambient temperature exceeds a certain value, these devices will malfunction, restart, or trigger high-temperature protection, resulting in poor reliability.

[0027] This utility model proposes a direct air-cooling system 100.

[0028] Please see Figs. 1-2In one embodiment of this utility model, the direct air cooling system 100 includes a wind chamber 1 and an electrical control box 2. The wind chamber 1 has a cooling space 11. The top of the cooling space 11 is provided with a pipe and a heat dissipation fin 12 connected to the pipe. The bottom of the cooling space 11 is provided with a fan 13 that blows air toward the heat dissipation fin 12. The electrical control box 2 is located outside the wind chamber 1. The electrical control box 2 is provided with electrical control equipment. The electrical control box 2 has a fitting side and an air inlet side 21 and an air outlet side 22 located at opposite ends of the fitting side. The fitting side is fitted with the wind chamber 1. The air inlet side 21 and the air outlet side 22 are respectively provided with an air inlet pipe 23 and an air outlet pipe 24. The air inlet pipe 23 and the air outlet pipe 24 are both connected to the electrical control box 2. The end of the air inlet pipe 23 away from the electrical control box 2 and the end of the air outlet pipe 24 away from the electrical control box 2 are both connected to the cooling space 11.

[0029] The direct air-cooling system 100 of this utility model operates as follows: a fan 13 blows cold air towards the heat dissipation fins 12, and heat exchange occurs through the heat dissipation fins 12, thereby cooling the hot steam in the pipe into water for subsequent recycling. The electrical control box 2 is connected to the cooling space 11 via an inlet pipe 23 and an outlet pipe 24. The inlet pipe 23 introduces cold air from the cooling space 11 into the electrical control box 2, where it exchanges heat with the electrical control equipment, removing the heat generated during operation and ensuring normal operation. The air after heat exchange enters the air chamber 1 through the outlet pipe 24. By directly drawing cold air from the air chamber 1 into the electrical control box 2, the structure is simple, fully utilizing the existing cold air resources within the air chamber 1, saving on the installation and use of other cooling mechanisms, reducing costs and increasing efficiency. Furthermore, by forming an air circulation with the air chamber 1, the electrical control box 2 has a large flow rate and low temperature of cold air, resulting in good circulation and timely removal of the large amount of heat generated by the frequency converter and other electrical control equipment, ensuring the normal operating temperature of the electrical control equipment and ensuring high reliability.

[0030] It should be noted that the fitting side is fitted or connected to the outer wall of the air chamber 1, thereby installing the electrical control box 2 on the outer wall of the air chamber 1 and maintaining stability.

[0031] In one embodiment, the electrical control box 2 has an air inlet side 21 and an air outlet side 22 on both sides along the horizontal direction. The air inlet side 21 and the air outlet side 22 are respectively provided with an air inlet and an air outlet. The air inlet pipe 23 and the air outlet pipe 24 are respectively connected to the electrical control box 2 through the air inlet and the air outlet.

[0032] Understandably, in this embodiment, the left and right sides of the electrical control box 2 are designated as the air inlet side 21 and the air outlet side 22, and air inlets and outlets are provided on the air inlet side 21 and the air outlet side 22. This can form an effective airflow path, allowing cooling air to smoothly enter the electrical control box 2 and further flow to remove the heat generated during the operation of the electrical control equipment, thereby maintaining the stability of the equipment during operation.

[0033] In another embodiment, the electrical control box 2 has an air inlet side 21 and an air outlet side 22 on its two vertical sides, which means that the air inlet side 21 and the air outlet side 22 are the upper and lower sides of the electrical control box 2, which can also achieve the same beneficial effect. The air inlet pipe 23 and the air outlet pipe 24 are arranged on opposite sides of the electrical control box 2, thereby ensuring that cold air can flow through the electrical control equipment and ensuring good heat dissipation.

[0034] In one embodiment, the height of the air inlet is lower than the height of the air outlet, wherein the air inlet is located near the bottom of the electrical control box 2, and the air outlet is located near the top of the electrical control box 2.

[0035] Understandably, by making the height of the air inlet lower than the height of the air outlet, it is easier to keep the cold air inside the electrical control box 2 while the hot air flows out. It should be noted that, due to the difference in mass between cold and hot air, hot air will flow upward relative to cold air. Therefore, setting the height of the air outlet higher facilitates the timely discharge of hot air and improves reliability.

[0036] In one embodiment, the end of the air intake pipe 23 away from the electrical control box 2 has an inlet, and the inlet extends into the cooling space 11 and is disposed toward the bottom of the cooling space 11.

[0037] Understandably, by setting the inlet toward the bottom of the cooling space 11, it is convenient for the fan 13 at the bottom of the cooling space 11 to blow air, so that cold air can enter the air intake pipe 23 from the inlet, thereby achieving stable air circulation for heat exchange and heat dissipation of the electrical control equipment.

[0038] In one embodiment, the intake pipe 23 includes an intake section 231 and a connecting section 232 that are connected to each other. The end of the connecting section 232 away from the intake section 231 extends out of the cooling space 11 and is connected to the electrical control box 2. The intake section 231 is located in the cooling space 11 and is arranged vertically. The end of the intake section 231 away from the connecting section 232 has an inlet.

[0039] Understandably, the intake section 231 is arranged vertically and located within the cooling space 11, allowing it to directly utilize the cold air within the cooling space 11. Since cold air is denser than hot air, it naturally sinks, making it easier for this cooler air to enter the vertically arranged intake section 231, thereby improving the heat dissipation effect.

[0040] In one embodiment, the intake pipe 23 is provided with a flared opening 233 communicating with the inlet, and the size of the flared opening 233 gradually increases from top to bottom in the horizontal direction. The design of the flared opening 233 facilitates the entry of cold air into the intake pipe 23 and improves the circulation effect of cold air.

[0041] In one embodiment, the end of the exhaust pipe 24 away from the electrical control box 2 has an outlet, which extends into the cooling space 11 and is positioned towards the top of the cooling space 11. Understandably, since hot air is lighter than cold air and generally rises, positioning the outlet of the exhaust pipe 24 towards the top of the cooling space 11 utilizes this natural phenomenon, making it easier for the hot air exhausted from the electrical control box 2 to rise and leave the interior of the electrical control box 2, preventing hot air from stagnating inside the electrical control box 2 and improving the efficiency of hot air exhaust.

[0042] In one embodiment, a waterproof cover 243 is installed on the air inlet pipe 23, and the waterproof cover 243 is located above the outlet. By providing the waterproof cover 243, water can be prevented from entering from the outlet and affecting the use of electrical control equipment, thus improving reliability.

[0043] In one embodiment, a spray device 14 is provided inside the cooling space 11. The spray device 14 is located below the heat dissipation fins 12. The spray device 14 includes a plurality of nozzles 141 that spray water toward the bottom of the cooling space 11. The plurality of nozzles 141 are spaced apart in a horizontal direction. It can be understood that by providing the spray device 14, which includes a plurality of spaced nozzles 141, the heat exchange effect of the heat dissipation fins 12 in the cooling space 11 can be effectively enhanced, thereby improving the cooling effect.

[0044] Specifically, the nozzle 141 can also be configured with multiple rows in the horizontal direction.

[0045] In one embodiment, the exhaust pipe 24 includes an inner pipe 242 and an outer pipe 241 that are connected to each other. The outer pipe 241 is located outside the cooling space 11 and the end of the outer pipe 241 away from the inner pipe 242 is connected to the electrical control box 2. The inner pipe 242 is located inside the cooling space 11, and an axial flow fan 244 that blows air toward the inner pipe 242 is provided on the outer pipe 241.

[0046] Understandably, by installing an axial flow fan 244 on the outer pipe 241, air can be forced from the electrical control box 2 to the cooling space 11, improving airflow and circulation efficiency. This helps to expel hot air from the electrical control box 2 more quickly, thereby effectively reducing the internal temperature of the electrical control box 2.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
