Title:
MULTI-PORT VALVE AND THERMAL MANAGEMENT SYSTEM HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/148010
Kind Code:
A1
Abstract:
A multi-port valve (100), comprising a valve housing (10) and a valve element (20). The valve housing (10) comprises several ports distributed in the circumferential direction, all the ports are divided into at least two groups of ports (11, 12), and each group of ports (11, 12) comprises a main port (13) and a plurality of sub-ports (14, 15). The valve element (20) is connected to the valve housing (10) in a relatively rotating manner, and at least two flow channels (21, 22) are arranged in the valve element (20). According to the fact that the valve element (20) rotates to different positions relative to the valve housing (10), the multi-port valve (100) has several working modes, and under the different working modes, the at least two flow channels (21, 22) are configured in such a way that one of the main ports (13) is in communication with one of the sub-ports (14, 15) in a selective manner . A thermal management system (200), comprising a multi-port valve (100) and several coolant branches connected to ports of the multi-port valve (100), wherein at least some of the coolant branches are in communication in series by means of flow channels of the multi-port valve (100) so as to form a closed loop.
