Abstract: A chassis and a power supply system include a body and a heat dissipation component configured to dissipate heat for heat generation modules in the body. The heat dissipation component includes a spacer board and at least one fan disposed on the spacer board. An annular air duct includes a first air duct surrounded by the spacer board and a second air duct located between the spacer board and sidewalls of the body, and the first air duct communicates with the second air duct. The annular air duct is formed in the body by using the spacer board, so that air flow can be implemented with a small quantity of fans, and temperatures of the air in the body are balanced, thereby improving a heat dissipation effect, reducing a quantity of fans, reducing space occupied by the fans, and increasing space for placing components in the body.

Each liquid supply device is connected to the at least one liquid storage device through a first multiport valve to obtain liquid and is connected to a temperature regulating device through a second multiport valve. The controller is configured to control the first multiport valve and the second multiport valve that are connected to the controller to be conducted or not to be conducted. When the first multiport valve and the second multiport valve are conducted, each liquid supply device outputs the obtained liquid to the temperature regulating device. The temperature regulating device regulates a temperature of the liquid injected by each liquid storage device, and then supplies the liquid to at least one battery system.
