[0001] The utility model belongs to the technical field of coolant transportation, and in particular relates to a large-caliber nylon tube with a coolant transportation function. Background Art

[0002] With the rapid development of new energy vehicles and electrochemical energy storage systems, more and more systems require larger and larger coolant flows, so it is necessary to develop large-diameter transport pipes and connectors to meet the transportation of large coolant flows.

[0003] In order to meet the transportation of large flow rates of coolant, metal steel pipes are generally used. The disadvantages are heavy weight and high price. They are generally industrial-grade products and it is difficult to meet the sealing performance requirements of the automotive industry or energy storage field at low temperatures. They also have poor corrosion resistance and often cannot meet the ten-year design life requirements. In addition, the connection of steel pipes is generally carried out by using a gasket plus a chuck. The gasket plus chuck method is large in size, difficult to install, and has a high cost. Therefore, a small number of nylon tubes are used to meet the transportation of large flow rates of coolant. However, nylon tubes often have poor sealing properties.

[0004] In order to solve the above-mentioned deficiencies of the prior art, there is an urgent need for a large-diameter nylon tube with a coolant transport function that is light in weight, has good sealing performance, is easy to install and disassemble. Utility Model Content

[0010] Preferably, it further comprises a clamp, a clamp groove is provided on the circumference of the main body joint, the pipe joint body comprises a horizontal portion 1, an inclined portion and a horizontal portion 2, the horizontal portion 1, the inclined portion and the horizontal portion 2 are integrally formed, the two ends of the inclined portion are respectively fixedly connected to the horizontal portion 1 and the horizontal portion 2, and the outer diameter of the horizontal portion 1 is smaller than the outer diameter of the horizontal portion 2;

[0011] The clamp groove is located directly above the inclined portion, and the clamp is installed in the clamp groove.

[0012] Preferably, the first sealing ring and the second sealing ring are both EPDM sealing rings.
