The invention provides an auxiliary water tank, a vehicle thermal management system, a vehicle thermal management method and a vehicle. The auxiliary water tank comprises a tank body, a partition plate, a flow dividing piece and a piston. A filling port is formed in the box body. The partition plate is arranged in the box body so as to divide the box body into a first cavity and a second cavity, and a flow passing channel allowing cooling liquid to flow between the first cavity and the second cavity is formed between the partition plate and the top wall or the side wall of the box body. The auxiliary water tank provided by the invention can act on at least two cooling circulation systems, so that the number of the auxiliary water tanks of the vehicle is reduced, the space is saved, and the assembly time and cost of the vehicle are reduced. The first cavity and the second cavity are formed through the partition plate, so that relative independence in a normal working state is guaranteed; and a flow passage is formed between the partition plate and the top wall or the side wall of the box body, so that the cooling liquid in one cavity can flow to the other cavity when the liquid level is higher than a certain degree, and the two cooling circulation systems can communicate with each other conveniently.
本申请提供一种副水箱、车辆热管理系统、车辆热管理方法和车辆。副水箱包括箱体、间隔板、分流件与活塞。箱体形成有加注口。间隔板设置于箱体内,以将箱体分隔为第一腔室和第二腔室,间隔板与箱体的顶壁或侧壁之间形成供冷却液在第一腔室和第二腔室之间流通的过流道。通过本申请提供的副水箱,可以作用于至少两个冷却循环系统,从而减少车辆的副水箱数量,节省空间,减少车辆的装配时间和成本。通过间隔板形成第一腔室和第二腔室,保证在正常工作状态下的相对独立性;间隔板与箱体的顶壁或侧壁之间形成过流道,使得其中一个腔室的冷却液液位高于一定程度时可以流到另一个腔室,便于两个冷却循环系统的互通。
