However, this cooling method has some shortcomings. For example, the fixing method of the cooling pipe is not stable enough, which may cause the cooling pipe to shake or fall off during the circulation, affecting the cooling effect. Therefore, a circulation cooling device for hydraulic oil is proposed to solve the above-mentioned problems. Utility Model Content

[0026] See also Figure 1-3 , a circulating cooling device for hydraulic oil, comprising a cooling pool 1, a cooling pipe 4 and a quick fixing assembly, wherein the cooling pipe 4 is located inside the cooling pool 1 and an end thereof passes through the front side of the cooling pool 1;

[0027] The quick fixing assembly includes a snap-in groove 2, a U-shaped groove 3 and a fixing module 5. The snap-in groove 2 is arranged on the inner walls on both sides of the cooling pool 1 and is snap-fitted with the fixing module 5. Two U-shaped grooves 3 are provided and opened at the top of the front side of the cooling pool 1. The two ports of the cooling pipe 4 are snap-fitted with the two U-shaped grooves 3 respectively.

[0028] In this embodiment, the two ports of the cooling pipe 4 are respectively a liquid inlet 401 and a liquid outlet 402 . The liquid inlet 401 is located inside the cooling pool 1 and one end thereof is bent downward and connected to a first connecting pipe 403 .

[0029] It should be noted that the liquid inlet 401 of the cooling tube 4 is designed to be bent downward, which helps the coolant to smoothly enter the interior of the cooling tube and reduces heat accumulation that may be generated due to poor liquid flow.

[0030] In this embodiment, one end of the liquid outlet 402 located inside the cooling pool 1 is connected to one end of the second connecting pipe 404 , and the other end of the second connecting pipe 404 is bent downward and connected to the first connecting pipe 403 .

[0031] It should be noted that the design of the liquid outlet 402 also takes into account the flow characteristics of the coolant. By connecting the second connecting pipe 404 and the first connecting pipe 403, a complete circulation path for the coolant is formed, while also meeting the requirements of bottom-in and top-out.

[0032] In this embodiment, the first connecting pipe 403 and the second connecting pipe 404 are both S-shaped bends, and the bending directions of the first connecting pipe 403 and the second connecting pipe 404 are perpendicular to each other.

[0033] It should be noted that the S-shaped curved design is not only aesthetically pleasing, but more importantly, can reduce the flow resistance of the coolant. By bending the pipe, the flow rate of the coolant can be effectively reduced, thereby reducing the heat and energy loss caused by excessive flow rate. At the same time, the bending directions of the first connecting pipe 403 and the second connecting pipe 404 are perpendicular to each other, making the entire cooling system structure more compact and saving space.

[0034] In this embodiment, the fixing module 5 is composed of a fixing end 501, an adjusting block 502 and a locking end 503 connected in sequence. The fixing end 501 is composed of an I-shaped part and a first threaded section. The I-shaped part is provided with a fixing hole and is fixed to the cooling pool by screws and bolts.

[0035] It should be noted that the design of the fixing module 5 fully considers the requirements of quick installation and stability. The design of the I-shaped parts and fixing holes of the fixing end 501 enables it to be firmly fixed on the inner wall of the cooling pool, ensuring the overall stability of the fixing module. The fixing method of screws and bolts makes the installation process simpler and faster.

[0036] In this embodiment, the adjusting block 502 is provided with a thread groove inside and anti-slip stripes outside, one end of the locking end 503 is provided with a second thread segment, and the two ends inside the locking end 503 are respectively threadedly connected with the first thread segment and the second thread segment.

[0037] It should be noted that the thread groove design and anti-slip stripes of the adjustment block 502 make its connection with the fixed end 501 and the locking end 503 more tightly and reliably, and the rotation is more convenient.

[0038] In this embodiment, a first locking block 504 and a second locking block 505 are further provided on the locking end 503. The first locking block 504 is welded to the end of the second threaded section. The second locking block 505 is provided with a small plug rod facing the side of the first locking block 504. A small through hole is opened on the first locking block 504. The aperture of the small through hole is larger than the small plug rod. The outside of the small plug rod is provided with a thread and is fixed by a nut after the small plug rod is connected to the first locking block 504.

[0039] It should be noted that the design of the first locking block 504 and the second locking block 505 further enhances the fixing effect of the fixing module on the cooling pipe. The first locking block 504 is fixed to the locking end 503 by welding, and the second locking block 505 is fixed by a nut after being plugged into the first locking block 504 through a small plug rod. This design not only makes the fixing process more flexible, but also can be adjusted according to the actual size of the cooling pipe to ensure the optimization of the fixing effect. At the same time, the design of the small through hole having a larger aperture than the small plug rod makes the plug-in process smoother and improves the installation efficiency.

[0040] Working principle:

[0041] Place the cooling tube 4 inside the cooling pool 1 so that its two ports: the liquid inlet 401 and the liquid outlet 402 correspond to the two U-shaped grooves 3 on the top of the front side of the cooling pool 1 respectively. Through a simple clamping operation, the two ports of the cooling tube 4 can be firmly fixed in the U-shaped groove 3, and the positioning of the cooling tube is preliminarily realized. Then, the I-shaped piece of the fixed end 501 is clamped with the clamping groove and slid to a suitable height, and then the adjusting block 502 is quickly threadedly connected with the locking end 503. After the first locking block 504 is clamped with one side of the cooling tube 4, the fixed end 501 and the adjusting block 502 are adjusted again and the fixed end 501 is fixed to the inner wall of the cooling pool by screws. The second locking block 505 is clamped on the other side of the cooling tube 4 and fixed with the nut after being plugged into the first locking block 504.

[0042] Beneficial effects:

[0043] The circulating cooling device for hydraulic oil realizes the rapid installation and positioning of the cooling pipe by adopting the clamping design of the U-shaped groove 3 and the port of the cooling pipe 4. The fixing module 5 is composed of a fixing end 501, an adjusting block 502 and a locking end 503. The cooling pipe can be quickly fixed by simple threaded connection and locking operation, thereby strengthening the support for the cooling pipe 4. At the same time, the liquid inlet 401 and the liquid outlet 402 of the cooling pipe 4 meet the requirements of bottom inlet and top outlet, and are connected by the first connecting pipe 403 and the second connecting pipe 404 with an S-shaped bend. This design not only reduces the flow resistance of the coolant and improves the cooling efficiency, but also makes the entire cooling system more compact and beautiful.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
