[0002] High temperature resistant coaxial cable for new energy vehicles is a high-performance cable designed for new energy vehicles, used to transmit high-frequency signals and electricity. This cable has excellent high temperature resistance and can maintain stable electrical performance in high temperature environments, ensuring the safe operation of new energy vehicles. During the production and manufacturing process of coaxial cables, the copper core of the cable needs to be quickly cooled after being plastic-coated at high temperature to form the cable. At present, the cable is generally immersed in a water tank filled with water and cooled by water cooling. However, as a large number of high-temperature cables are cooled by water, the water temperature in the water tank will slowly rise, and the subsequent cooling effect will become worse. Therefore, we proposed a cooling device for high temperature resistant coaxial cables for new energy vehicles to solve the above problems. Utility Model Content
