Abstract
A negative pressure liquid cooling system and a method for controlling a negative pressure liquid cooling system are provided, and the negative pressure liquid cooling system separately controls pressures at an inlet and an outlet of a cold plate, so that the pressures at the inlet and the outlet of the cold plate remain negative. In this way, when a pipeline between the inlet and the outlet of the cold plate is perforated, a pressure at the outlet of the cold plate can be separately controlled to remain negative, so that a coolant is suppressed in the pipeline, and a coolant leakage phenomenon is avoided. Therefore, damage or a security threat to a to-be-cooled electronic device that is caused by leakage of a conductive operating medium such as water is avoided.
