[0031] Specifically, the output end of the liquid nitrogen pump 301 penetrates through the top surface of the liquid nitrogen tank 3 and extends inward. The shape of the cooler main body 1 is a spiral coil structure, and both ends thereof penetrate through the inner wall of the vacuum chamber 6 and are respectively communicated with the input end of the liquid nitrogen pump 301 and the inner bottom end of the liquid nitrogen tank 3. The heat conduction layer 602 is located inside the inner side of the vacuum chamber 6;

[0032] In this implementation scheme, the liquid nitrogen pump 301 is mainly used to guide the liquid nitrogen in the liquid nitrogen tank 3, so that the liquid nitrogen flows through the cooling pipe 601, passes through the vacuum chamber 6 and returns to the liquid nitrogen tank 3. The cold conduction layer 602 is mainly used to absorb the cold air generated by the liquid nitrogen and transfer it to the cooling chamber 7, thereby achieving the effect of cooling the lubricating oil.

[0033] Specifically, the output end of the driving motor 401 penetrates through the top surface of the top cover 4 and is fixed to the top end of the stirring rod 403. The top inner wall of the cooling chamber 7 extends to the top surface of the cooler main body 1. The bottom end of the stirring rod 403 extends to the inner bottom end of the cooling chamber 7. The stirring blades 405 are spirally wound around the outer surface of the stirring rod 403.

[0034] In this implementation scheme, the driving motor 401 is mainly used to drive the stirring rod 403, so that the stirring rod 403 drives the stirring disk 404 and the stirring blades 405 to rotate, thereby achieving the effect of vigorously stirring the lubricating oil and facilitating the improvement of the lubricating oil cooling efficiency.

[0035] It should be noted that the driving motor 401, the liquid nitrogen pump 301 and the electric push rod 505 are respectively electrically connected to the controller through wires.

[0036] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the sealing and opening / closing mechanism 5 includes an annular sealing groove 501, a sealing block 502, an upper mounting block 503 and a lower mounting block 504. The annular sealing groove 501 is opened on the top surface of the cooler main body 1. The sealing block 502 is fixedly installed on the bottom side of the top cover 4. The upper mounting block 503 is fixedly arranged on the outer surface of the top cover 4. The lower mounting block 504 is fixedly installed on the outer surface of the cooler main body 1. The top of the lower mounting block 504 is fixedly provided with the electric push rod 505.

[0037] Specifically, the cross-sectional shape of the sealing block 502 is a circular ring structure, and its outer surface is in sealing fit with the inner wall of the annular sealing groove 501. The upper mounting block 503 is directly above the lower mounting block 504. The telescopic end of the electric push rod 505 is fixedly connected to the bottom end of the upper mounting block 503.

[0038] In this implementation scheme, the electric push rod 505 is mainly used to drive the upper mounting block 503 to open and close the top cover 4.

[0039] Working process of the utility model: When using a lubricating oil cooler, first add the lubricating oil to be cooled into the cooling chamber 7 through the oil inlet 402. Then drive the liquid nitrogen pump 301. Under the action of the liquid nitrogen pump 301, liquid nitrogen flows out from the bottom of the liquid nitrogen tank 3 through the cooling pipe 601 and passes through the vacuum chamber 6. During the flow of liquid nitrogen, its cold air will diffuse outwards and be transmitted towards the cooling chamber 7 through the heat conduction layer 602, and then flow back into the liquid nitrogen tank 3. In this way, the cold air can be transported to the cooling chamber 7 through circulation. At this time, start the drive motor 401. The output end of the drive motor 401 drives the stirring rod 403 to rotate, and the stirring rod 403 drives the stirring disc 404 and the stirring blades 405. Under the rotational contact of the stirring disc 404, the stirring blades 405 and the lubricating oil, the lubricating oil circulates in different directions, ensuring the uniformity of the temperature of each part of the lubricating oil, facilitating the rapid cooling of the lubricating oil, and meeting the needs of the users. Further, when it is necessary to open the top cover 4, start the electric push rod 505. The output end of the electric push rod 505 drives the upper mounting block 503 and the top cover 4 to move upwards, and the top cover 4 drives the sealing block 502 to gradually separate from the annular sealing groove 501, thus completing the convenient opening of the top cover 4, facilitating the subsequent cleaning or maintenance of the cooler main body 1, and improving the practical effect of the cooler.

[0040] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
