[0002] Big data, or massive amounts of data, refers to datasets so large or complex that traditional data processing applications are inadequate. Big data can also be defined as large amounts of unstructured or structured data from a variety of sources. From an academic perspective, the emergence of big data has fostered novel research across a wide range of topics. This has also led to the development of various big data statistical methods. Big data does not rely on statistical sampling methods; it simply observes and tracks what occurs. Therefore, big data often contains data that exceeds the capacity of traditional software to process within an acceptable timeframe. Due to technological advances, the ease with which new data can be released, and the transparency mandated by most governments worldwide, big data analysis is becoming increasingly prominent in modern research.

[0034] A heat dissipation method for a big data network cabinet heat dissipation structure comprises the following steps:

[0035] 1) The coolant tank 14 is filled with coolant, and the circulating pump 15 is operated. The circulating pump 15 operates to deliver the coolant in the coolant tank 14 to the water pipe 16, and then delivers it to the inner cavity 13 of the heat sink 11 through the water pipe 16. At the same time, the fan 22 operates to generate heat dissipation air. The heat dissipation air is delivered to the interior of the housing 10 through the air supply pipe 23, and then passes through the through hole 12. In this way, after the heat dissipation air is cooled by the coolant, the heat dissipation air can effectively dissipate heat for the big data host placed on the placement plate 6;

[0036] 2) The used coolant flows through the return pipe 17 to the inner tube 19 and is discharged through the mushroom plate 20 at the top of the inner tube 19. After cooling, the discharged coolant flows to the collection cover 21 and then flows through the collection cover 21 and the vertical pipe 18 to the coolant tank 14, facilitating the recycling of the coolant;

[0037] 3) When in use, the motor 28 is working, and the motor 28 drives the screw rod 25 to rotate. The rotation of the screw rod 25 cooperates with the threaded hole 29 opened on the moving block 27, so that the moving block 27 moves from the left end of the screw rod 25 to the right end. The movement of the moving block 27 drives the L-shaped pressure rod 31 to move until the L-shaped pressure rod 31 abuts against the host placed on the placement plate 6, and the big data host is fixed. When disassembling, the moving block 27 moves from the right end of the screw rod 25 to the left end, and the movement of the moving block 27 drives the L-shaped pressure rod 31 to move until the L-shaped pressure rod 31 is detached from the host placed on the placement plate 6, and the big data host can be disassembled;

[0038] 4) When the base 5 of the box body 1 needs to be reinforced, the push-pull block 33 is pulled out of the plug-in cavity 32 through the push-pull ring 38. After pulling it out, the push-pull block 33 is pulled out, and the support thread column 37 in the groove 36 is rotated, and the support thread column 37 is turned downward to support on the support surface. The base 5 of the box body 1 can be reinforced by the support thread column 37 and the push-pull block 33, thereby improving the stability of the base 5.

[0039] Working principle: When the present invention is used, the coolant is filled in the coolant tank 14, and the circulation pump 15 is working. The circulation pump 15 works to transport the coolant in the coolant tank 14 to the water pipe 16, and then transported to the inner cavity 13 in the heat sink 11 through the water pipe 16. At the same time, the fan 22 is working, and the fan 22 generates heat dissipation wind. The heat dissipation wind is transported to the interior of the shell 10 through the air supply pipe 23, and then passes through the through hole 12. In this way, after the heat dissipation wind is cooled by the coolant, the heat dissipation wind can better dissipate heat for the big data host placed on the placement plate 6; the used coolant flows to the inner tube 19 through the return pipe 17, and is discharged through the mushroom plate 20 at the top of the inner tube 19. The discharged coolant flows to the collection cover 21 after cooling, and flows to the coolant tank 14 through the collection cover 21 and the vertical pipe 18, which is convenient for the recycling of the coolant; when in use, the motor 28 is working, and the motor 28 drives the screw rod 25 to rotate, and the screw rod 25 rotates The movable block 27 is moved toward the right end by the left end of the screw rod 25, and the movable block 27 drives the L-shaped pressure rod 31 to move until the L-shaped pressure rod 31 is disengaged from the host placed on the placement plate 6, and the large data host can be removed.

[0040] Beneficial effects: The present invention has a novel structure and an ingenious conception, and is convenient for dissipating heat for a large data host placed on the placement plate 6, with a good heat dissipation effect. At the same time, the large data host can be positioned, and the overall stability is good.
