The invention relates to the technical field of immersion liquid cooling
data center cooling, and particularly provides a single-phase immersion liquid cooling
server circulation cooling method and
system, and the method comprises the steps: comparing the real-time temperature of a cooling liquid with a preset temperature threshold value, transmitting a first
program instruction by a
control system, and carrying out an immersion liquid cooling cabinet internal circulation mode; or a second
program instruction is sent, and a heat exchange circulation mode is carried out; after the heat exchange circulation mode is started, a main liquid outlet pipeline is opened; the cooling liquid flows back to the liquid outlet of the immersed liquid cooling cabinet through the
backflow branch pipeline, the real-time temperature of the cooling liquid and the preset temperature threshold value are continuously judged, and switching between the internal circulation mode and the heat exchange circulation mode of the immersed liquid cooling cabinet is achieved according to the comparison result. The
system comprises an immersed liquid cooling cabinet, a
branch pipeline valve, a main pipeline valve, a main liquid outlet pipeline, a pump, a
heat exchanger and a
branch pipeline. According to the invention, the topology reconstruction capability of the cooling liquid flow is realized, and local circulation and global circulation are dynamically switched according to the
thermal load.
