Negative pressure cooling distribution unit heat dissipation system

Abstract

In the present disclosure, a negative pressure cooling distribution unit (CDU) heat dissipation system comprises a cold plate assembly, a liquid pump, and a heat exchanger. A liquid outlet of the cold plate assembly is connected to a liquid inlet of the liquid pump, the liquid pump is to pressurize liquid flow from the liquid outlet of the cold plate assembly. A liquid outlet of the liquid pump is connected to a liquid inlet of the heat exchanger, the heat exchanger is to perform heat exchange, and a liquid outlet of the heat exchanger is connected to a liquid inlet of a pressure regulator; the pressure regulator is to adjust liquid pressure within a pipeline to below one atmosphere. A liquid outlet of the pressure regulator is connected to a liquid inlet of the cold plate assembly. The first pressure detector is to detect a first pressure at the liquid inlet of the cold plate assembly; and the first temperature detector is to detect a first temperature at the liquid inlet of the cold plate assembly; wherein the first temperature is regulated by the heat exchanger to be maintained at a set temperature value. The system in the examples of the present disclosure operates safely and reliably, with excellent fluid control responsiveness and simple structure and control logic.
