Title:
THERMAL MANAGEMENT COMPONENT, BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/098322
Kind Code:
A1
Abstract:
A thermal management component (3), a battery (100) and an electric device. The thermal management component (3) comprises a body (31), the body (31) being internally provided with a first main flow channel (34), a second main flow channel (35) and a plurality of first branch flow channels (36), wherein the plurality of first branch flow channels (36) are arranged side by side; two ends of each first branch flow channel (36) are respectively in communication with the first main flow channel (34) and the second main flow channel (35); each first branch flow channel (36) comprises an intermediate section (361) and two end sections (362); and the cross sectional area of the intermediate section (361) is less than the cross sectional area of the end sections (362). The provided thermal management component (3) is used for the battery (100), has high heat exchange efficiency, and can reduce the average temperature of the battery (100), thereby alleviating the problem of runaway caused by the temperature of the battery (100) being excessively high; and the temperature rise of a middle region of the battery (100) is also reduced, and the temperature difference between the middle region of the battery (100) and an outside region of the battery (100) is reduced, thereby alleviating the problem of lithium plating caused by overcharging due to an excessively large temperature difference between different regions of the battery (100), and effectively improving the safety of the battery (100).
