Abstract

The present disclosure relates to the field of power supply and an uninterruptible power supply is disclosed. The uninterruptible power supply includes a first power board, a liquid cooling plate, a second power board, a first set of power devices arranged on the first power board, and a second set of power devices arranged on the second power board; the liquid cooling plate is stacked between the first power board and the second power board, and is configured to dissipate heat from the first set of power devices and the second set of power devices; the liquid cooling plate comprises an inlet, an outlet, and a cooling passage communicating the inlet and the outlet, and the cooling passage is configured to accommodate a coolant; and the first set of power devices and/or the second set of power devices includes a temperature-sensitive component and multiple power components, and the multiple power components are located in front of the temperature-sensitive component along a flow direction of the coolant in the cooling passage. In the present disclosure, heat dissipation for the temperature-sensitive component with higher temperature sensitivity is prioritized to ensure a service life of the uninterruptible power supply, and then heat dissipation of other power components is performed, so that liquid cooling for all power components is suitably considered.
