Description

Technical Field

[0001] This utility model relates to the field of automotive pipeline leak prevention detection technology, and in particular to a leak prevention detection device for cooling system pipelines in new energy vehicles. Background Technology

[0002] The primary function of the cooling system in new energy vehicles is to maintain key components such as the battery, motor, and power electronics within their optimal operating temperature range. Unlike traditional gasoline vehicles, the cooling system in new energy vehicles needs to manage the temperature of both the electric motor and the battery pack simultaneously, as these components generate a significant amount of heat during operation.

[0003] In practical use, the coolant lines of the cooling system in new energy vehicles are prone to leakage due to physical damage. Due to the complexity of the internal structure of new energy vehicles, the coolant lines may be damaged by vibration, collision, or long-term wear during vehicle operation, thus causing leakage problems.

[0004] In addition, loose joints are also a significant factor leading to pipe leaks. Joints in the cooling system connect various components; if a joint is not installed correctly or becomes loose due to prolonged vibration, coolant may leak from the joint.

[0005] The aging of coolant piping should not be ignored. Over time, piping materials may gradually degrade due to prolonged exposure to harsh environments such as high temperature and high pressure, leading to thinner pipe walls, reduced strength, and ultimately, leaks.

[0006] A leak in the cooling system will severely impact the performance and safety of new energy vehicles. Leaks can cause the coolant level to drop, affecting cooling efficiency and potentially leading to system overheating, which can damage critical components such as the battery and motor. In extreme cases, overheating can even cause safety incidents such as fires. Utility Model Content
