[0044] In the above embodiment, the diffuser head 8 can further improve the uniform distribution of wind power inside the cabinet body 1. When the wind power is transmitted to the diffuser head 8 through the telescopic tube 4, the diffuser head 8, which is in a horn shape with an opening facing the middle of the cabinet body 1, evenly diffuses the wind power under its action, so that it can better cover each position inside the cabinet body 1, especially the positions far from the diffuser head 8. This not only improves the heat dissipation effect, but also ensures that the equipment inside the cabinet body 1 is evenly cooled. At the same time, the setting of the diffuser head 8 also increases the fluidity of the wind power inside the cabinet body 1, making the air flow in the cabinet space more sufficient and improving the heat dissipation efficiency.

The setting of the exhaust side wall 9, which covers the entire exhaust through-hole, further improves the practicability of the exhaust through-hole. The exhaust ports 10 are formed on both sides of the exhaust side wall 9 in the vertical direction, enabling the wind force to form a cross-flow when discharged, thereby improving the exhaust efficiency. At the same time, for the sealing of the top and the large surface ends, it can also prevent dust from entering the cabinet body 1. In addition, the exhaust side wall 9 is detachably connected to the cabinet body 1, facilitating installation or disassembly according to actual needs, and increasing the flexibility and convenience of use.

The exhaust fans 11 are arranged on the inner side wall of the exhaust side wall 9, and their air outlets face the exhaust ports 10. When the exhaust fans 11 are started, the hot air inside the cabinet body 1 can be quickly discharged through the exhaust ports 10, forming a strong air flow circulation, so as to achieve the purpose of rapid heat dissipation. At the same time, the plurality of exhaust fans 11 are arranged at equal intervals, ensuring the uniform distribution of the wind force inside the cabinet body 1 and improving the uniformity and efficiency of heat dissipation.

[0049] In one embodiment, a plurality of support arms 12 are arranged inside the cabinet body 1.

A support plate 13 is provided at the top end of the support arm 12, and heat dissipation fins 14 are fixedly connected to the bottom end of the support plate 13.

[0050] In the above embodiment, the heat dissipation fins 14 further enhance the heat dissipation performance of the DTU cabinet. The support plate 13 is supported by the support arm 12 for placing electronic devices. The heat dissipation fins 14 are firmly installed on the bottom surface of the support plate 13 to ensure that the fins are in full contact with the air inside the cabinet body 1, effectively increasing the heat dissipation area. When the temperature of the device rises, the heat dissipation fins 14 can quickly absorb heat and dissipate it into the air, not only improving the heat dissipation efficiency, but also ensuring the stable operation of the devices inside the cabinet body 1. At the same time, the installation position of the heat dissipation fins 14 is reasonable and does not occupy too much space inside the cabinet body 1, keeping the interior space of the cabinet body 1 clean.

[0051] Reference Figure 4 , in an embodiment, it further includes a cabinet door 15. The cabinet door 15 is rotatably connected to the cabinet body 1.

The cabinet door 15 is provided with a positioning groove corresponding to the positioning protrusion so that the moisture-proof board is detachably connected to the cabinet door 15.

[0052] In the above embodiment, the cabinet door 15 provides a convenient way to open and close the cabinet body 1, and further enhances the moisture-proof performance of the cabinet body 1 through the setting of the moisture-proof board. The moisture-proof board is made of moisture-proof material and can effectively prevent the entry of external humid air into the cabinet body 1, protecting the devices inside the cabinet body 1 from moisture damage. By setting a positioning protrusion at one end of the moisture-proof board facing the cabinet door 15 and a corresponding positioning groove on the cabinet door 15, the detachable connection between the moisture-proof board and the cabinet door 15 is realized. This not only facilitates the installation and disassembly of the moisture-proof board, but also ensures the close fit between the moisture-proof board and the cabinet door 15. At the same time, the setting of the moisture-proof board also increases the sealing performance of the cabinet door 15, further preventing the entry of dust and impurities and keeping the interior environment of the cabinet body 1 clean and dry.
