Description

Technical Field

[0001] This utility model relates to the field of power supply technology, specifically to an uninterruptible power supply. Background Technology

[0002] An uninterruptible power supply (UPS) is a device that provides a continuous and stable power supply to a load when the mains power fails or other power outages occur. This includes online UPS systems. When the mains power is normal, the mains power is rectified into DC power, which charges the battery and is then converted back into AC power by an inverter to power the load. When the mains power fails, the battery discharges and the inverter continues to provide AC power to the load. Online UPS systems output high-quality AC power and effectively isolate various interferences from the power grid.

[0003] The existing uninterruptible power supply still has the following problems when in use: when its battery pack is charging and discharging, its battery pack is prone to heat accumulation. Since the battery pack and the main power supply are both located in the same housing, the heat accumulation of the battery pack not only poses a safety hazard to itself, but also affects the normal operation of the main power supply.
