Description

Technical Field

[0001] The utility model relates to the technical field of battery thermal management, and more particularly to a thermal management pipeline that is easy to install. Background Art

[0002] China is vigorously promoting new energy vehicles and energy storage projects. The market for new energy batteries is enormous. New energy batteries generate heat during charging and discharging. High temperatures significantly reduce the battery's cycle life and pose safety risks during high-rate charging. Therefore, new energy batteries require cooling. There are four main battery cooling methods: natural cooling, air cooling, liquid cooling, and direct cooling. Natural cooling is the most basic and simplest cooling method. It relies on ambient temperature for passive heat dissipation, utilizing natural convection to dissipate heat without requiring additional energy input. Air cooling actively promotes air flow through fans to improve heat dissipation. Liquid cooling achieves efficient heat dissipation by circulating coolant through the battery pack. Direct cooling systems directly introduce refrigerant into the battery cooling ducts for efficient heat exchange. Currently, liquid cooling is the mainstream cooling method for automotive battery thermal management. Its high efficiency, flexibility, and reliable thermal management make it the most popular power battery cooling method. However, the confined space within the battery pack makes conventional cooling hoses difficult to bend and install. Some hoses are prone to kinking at small bend radii, resulting in poor coolant flow, which can compromise cooling efficiency and even create hazards. To address this issue, we have proposed a thermal management system that is easy to install. Utility Model Content
