Provided is an integrated multi-way solenoid valve (100). The integrated multi-way solenoid valve (100) includes: a mounting panel (110), N channel interfaces (111) being defined on the mounting panel (110) and arranged in a first predetermined pattern, where N is an integer greater than or equal to 5; a valve seat (120) of a cylindrical shape, the valve seat (120) being fixedly connected to the mounting panel, and N openings (121) being defined on the cylindrical valve seat and in communication with N channel interfaces correspondingly; a valve cartridge (130) of a cylindrical shape, the valve cartridge being disposed in the valve seat in a close engagement manner with the valve seat, and a plurality of communication grooves (131) being defined on a circumferential surface of the valve cartridge and arranged in a second predetermined pattern; and a driving assembly (140) in transmission connection with the valve cartridge, the driving assembly being configured to drive the valve cartridge to rotate by a predetermined angle to bring at least one target communication groove of the plurality of communication grooves into communication with a plurality of target openings of the N openings, to allow for communication between the channel interfaces corresponding to the plurality of the target openings. Each of the at least one target communication groove is in communication with at least two of the plurality of target openings. The integrated multi-way solenoid valve can save space and cost, and make a pipeline distribution aesthetic pleasing. Provided further is a vehicle thermal management system for the integrated multi-way solenoid valve.
