With the rapid development of new energy vehicle technology, the thermal management problem of high voltage wiring harness and connector has become increasingly prominent. How to ensure that the wiring harness and connector will not overheat at high power output is the key to ensure the safe and stable operation of new energy vehicles.The design of the thermal management system of new energy high voltage wiring harness and connector is mainly based on the in-depth understanding of its working environment and the precise application of the principle of heat conduction. As an important part of power transmission, high voltage wiring harness will generate a lot of heat at high power output. If the heat cannot be effectively dissipated, it will cause the temperature of the wiring harness to rise, and may even cause fire or equipment damage. Therefore, the primary task of the thermal management system is to ensure the effective transfer and dissipation of heat.To achieve this goal, the thermal management system adopts a variety of technical means. First of all, the conductors and insulation materials of the high voltage wiring harness are carefully selected to ensure that they have good thermal stability and thermal conductivity. The conductors are usually made of high purity copper or copper alloys, which not only have good electrical conductivity, but also can effectively transfer heat from the inside of the wiring harness to the outside. At the same time, the insulation material also uses high temperature resistant and thermally stable materials, such as cross-linked polyethylene (XLPE), to ensure that it can maintain good insulation performance in high temperature environments.Secondly, the thermal management system also reduces the risk of temperature rise through reasonable wiring harness layout and heat dissipation design. The layout of the wiring harness should try to avoid heat accumulation, and use heat sinks, fans and other heat dissipation components to enhance the heat dissipation effect. In terms of connectors, the heat transfer efficiency can be further improved by optimizing the design of the contact surface and using materials with good thermal conductivity.In addition, the thermal management system is also equipped with intelligent equipment such as temperature sensors and controllers to monitor the temperature of high-voltage wiring harnesses and connectors in real time, and adjust the heat dissipation intensity according to actual conditions. This intelligent control strategy can automatically adjust the heat dissipation strategy according to different working conditions and environmental conditions to achieve the best thermal management effect.In summary, the design of the thermal management system of new energy high voltage wiring harness and connector is a complex and delicate process, which involves material selection, wiring harness layout, heat dissipation design and intelligent control. Through scientific design and effective technical means, it can be ensured that the high-voltage wiring harness and connector will not overheat at high power output, thereby ensuring the safe and stable operation of new energy vehicles. In the future, with the continuous development of new energy vehicle technology, thermal management systems will continue to innovate and improve, providing stronger support for the development of new energy vehicles.
