Description

TECHNICAL FIELD

[0001] The utility model relates to the field of uninterruptible power supply, especially an immersion liquid cooling mechanism for UPS. BACKGROUND

[0002] UPS, uninterruptible power supply, is a device that can provide continuous and stable power supply. It is widely used in various places that require uninterrupted power supply, such as data centers, medical equipment, communication equipment, etc. UPS can quickly switch to battery power mode when the mains power is cut off or the voltage is unstable, ensuring that the connected devices can continue to run and avoiding losses caused by power interruption.

[0003] The main heat dissipation methods of uninterruptible power supply include air cooling and heat pipe cooling. Air cooling is to blow air through the heat sink inside the UPS by a fan to take away the heat on the heat sink, achieving the effect of heat dissipation. Heat pipe cooling is to use the principle that the working fluid in the heat pipe absorbs heat at the evaporation end and then releases heat at the condensation end to conduct the heat inside the UPS to the outside for heat dissipation.

[0004] The existing heat dissipation methods of uninterruptible power supply have some shortcomings. The air cooling method produces a lot of noise during the heat dissipation process, which causes interference to the use environment. Although the heat pipe cooling method has less noise, its heat dissipation efficiency is limited by the size and layout of the heat pipe, making it difficult to achieve efficient heat dissipation. More importantly, neither air cooling nor heat pipe cooling can achieve comprehensive and uniform heat dissipation of all heat-generating components inside the UPS, which is prone to cause local overheating and affect the stability and reliability of the UPS. In addition, with the continuous improvement of the power of UPS, its heat dissipation demand is also increasing, and the existing heat dissipation methods have been difficult to meet the heat dissipation demand of high-power UPS.
