Description

[Technical field]

[0001] The utility model relates to the technical field of cooler copper tubes, in particular to a leak-proof copper tube for a cooler. [Background technology]

[0002] A cooler is a type of heat exchange equipment used to cool a fluid, usually using water or air as a coolant to remove heat. It can be mainly divided into a tube-and-shell cooler, a plate cooler, and an air-cooled cooler. A cooler is a heat exchange device commonly used in metallurgy, chemical industry, energy, transportation, light industry, food, and other industrial sectors. Existing coolers are mainly composed of fins and copper tubes. The copper tube is fixed on the fins and liquid is allowed to enter the copper tube, thereby achieving heat exchange of the liquid. For the inlet of the copper tube, threads are generally provided at both ends of the copper tube, which are connected to an external inlet pipe through the threads, thereby achieving transmission of the liquid. When the threads are connected to an external inlet pipe, in order to prevent leakage at the connection between the inlet pipe and the copper tube, raw tape is used. By winding multiple layers of raw tape on the threads, the threads are matched with the external inlet pipe, thereby preventing leakage of the copper tube and the inlet pipe.

[0003] Although the above technical solution can achieve leak-proofing at the connection between the liquid inlet pipe and the copper tube, since personnel rely entirely on experience in the process of winding the raw tape, if the raw tape is wound too much, it is easy to cause the subsequent threads on the liquid inlet pipe to be difficult to install on the copper tube. If the raw tape is wound too little, it is easy to cause leakage at the connection between the copper tube and the liquid inlet pipe when the subsequent liquid is transmitted, thereby causing the copper tube to have a reduced leak-proof effect during the liquid transmission process. [Utility Model Content]

[0004] The utility model aims to solve the problems in the prior art and provides a leak-proof copper tube for a cooler, which can prevent the copper tube from leaking.
