Description

Technical Field

[0001] The utility model relates to the technical field of coolers, in particular to a double-tube cooler. Background Art

[0002] A twin-tube cooler, also known as a shell-and-tube cooler or duplex cooler, consists of two oil coolers of equal size and a three-way valve assembly. One cooler is used in operation, while the other serves as a backup, ensuring continuous and stable cooling. Its compact structure facilitates cleaning, inspection, and maintenance, achieving cooling through the flow of water in the circulating water pipes. Widely used in fields such as plastics machinery, hydraulic equipment, and air compressors, this cooler is available in a variety of materials and can be selected based on the location and water system conditions to meet cooling needs under different operating conditions.

[0003] Existing double-tube coolers excel in efficient heat dissipation and stable operation, but they have also exposed some shortcomings during long-term use. Specifically, due to the complex and difficult-to-access internal structure of the cooler, scale and impurities are easily accumulated on the inner wall, affecting cooling efficiency and fluid flow. Traditional cleaning methods mostly rely on manual or chemical cleaning, which is not only time-consuming and labor-intensive, but may also damage the equipment or affect the cooling water quality. In addition, the discharge of residual liquid and cleaned impurities often becomes a problem, increasing maintenance costs and difficulty. Therefore, to solve the above problems, we propose a double-tube cooler. Utility Model Content

[0024] Working principle:

[0025] In the first step, when the double-tube cooler is cleaned, the control valves 17 on the connecting pipe 11 and the connecting pipe 2 12 are turned to open the two slag discharge pipes 16, and then the servo motor 21 is started. The output shaft of the servo motor 21 drives the transmission wheel 1 22 to rotate, and the transmission wheel 1 22 is forced to rotate to drive the synchronous belt 24, and the synchronous belt 24 is forced to drive the transmission wheel 2 23 to rotate, and the transmission wheel 1 22 rotates to drive the threaded shaft 1 25 to rotate, and the transmission wheel 2 23 is forced to drive the threaded shaft 2 26 to rotate, and the threaded shaft 1 25 and the threaded shaft 2 26 are forced to adjust the threads to drive the cleaning extrusion scraper 27 to move. Because the thread directions of the two cleaning extrusion scrapers 27 are opposite, they are located at the connecting pipe 1 and 2. The two cleaning extrusion scrapers 27 in the connecting pipe 11 and the connecting pipe 2 12 move relative to each other, and the two cleaning extrusion scrapers 27 move relative to each other to clean the inner walls of the connecting pipe 11 and the connecting pipe 2 12, and at the same time squeeze the residual liquid in the connecting pipe 11 and the connecting pipe 2 12 out from the slag discharge pipe 16. By adding two cleaning extrusion scrapers 27 to the double-tube cooler, during the cleaning process of the double-tube cooler, the servo motor 21 is started to drive the two cleaning extrusion scrapers 27 to move relative to each other, thereby achieving the purpose of cleaning the inner wall of the double-tube cooler, and at the same time, the residual liquid in the double-tube cooler and the cleaning impurities are discharged from the slag discharge pipe 16, which effectively improves the practicality of the device.

[0026] The second step is to install the double-tube cooler by installing the support base 1 at the installation point, and then respectively install the two head 2 15 on one side of the connecting pipe 1 11 and the connecting pipe 2 12 with flanges, and then fix the head 14 with the threaded shaft 1 25 to the connecting pipe 1 11 by flanges, and plug the threaded shaft 1 25 into the rotating bearing 18 of the head 2 15 on the side of the connecting pipe 1 11, and then fix the head 14 with the threaded shaft 2 26 to the connecting pipe 2 12 by flanges, and plug the threaded shaft 2 26 into the connecting pipe 1 It is fixed on the rotating bearing 18 of the head 2 15 on one side of the connecting pipe 1 11, and then the output shaft of the servo motor 21 is fixedly connected to the transmission wheel 1 22, and the synchronous belt 24 is sleeved on the transmission wheel 1 22 and the transmission wheel 2 23. The installation is completed. By designing and adding the threaded shaft 1 25 and the threaded shaft 2 26 on the double-tube cooler to the head 1 14 and the head 2 15 on both sides, the device can be disassembled more conveniently during the inspection and maintenance of the device, thereby effectively improving the practicality of the device.
