Description

Technical Field

[0001] The utility model relates to the technical field of breathable membrane installation, in particular to a breathable membrane installation structure. Background Art

[0002] With the rapid development of the automotive industry, the intelligent thermal management system (ITMS) is particularly critical. This system combines advanced sensor networks, complex control algorithms, and efficient communication protocols to achieve refined management of vehicle temperature and to ensure that key components of the vehicle are within a more reasonable operating temperature range.

[0003] First, the intelligent thermal management system uses a series of high-precision sensing devices, such as thermocouples, infrared sensors, and pressure and humidity sensors, to achieve comprehensive monitoring of the vehicle environment. These sensors accurately measure the temperature distribution of each unit to ensure the uniformity of temperature in each part, thereby preventing local overheating or uneven heating from negatively affecting vehicle performance. Some leading intelligent thermal management systems use adaptive and machine learning technologies, which can self-optimize based on long-term operating data. These systems continuously learn and adjust their parameters to adapt to different usage patterns and environmental conditions, thereby improving overall energy efficiency and performance.

[0004] In addition, an important feature of the intelligent thermal management system is its high integration with other key systems of the vehicle. Through vehicle communication networks, such as the controller area network (CAN) or on-board Ethernet, ITMS can exchange data with the power control unit, battery management system (BMS), etc., forming a collaborative multi-system complex. This integration not only improves the energy efficiency of the entire vehicle, but also optimizes the user's driving experience.

[0005] Normal controllers use a breathable valve, which has the disadvantage of requiring high dimensional accuracy, generally requiring metal parts, and requiring secondary processing on the assembly surface. The breathable valve cannot be tested for overall air tightness after installation. Utility Model Content
