[0001] The invention belongs to the technical field of heat dissipation of electronic equipment, and in particular relates to an immersion liquid cooling heat dissipation circulation control system. Background Art

[0002] Fast, stable and energy-efficient heat dissipation is a key concern in the design of high-density heating scenarios such as supercomputing / intelligent computing data centers, 6G base stations, battery thermal management and new energy. If the environment in which electronic equipment operates is allowed to heat up or become unstable over time, the reliability and service life of the electronic equipment will be reduced. Maintaining a proper thermal environment is critical to the normal operation and service life of these electronic devices in the above scenarios. In addition, high-density heating scenarios have an urgent need for energy conservation and consumption reduction. This requires more effective and efficient heat dissipation solutions, especially when cooling these high-density electronic devices.

[0003] The traditional immersion liquid cooling heat dissipation control system adopts a quantitative flow rate. The flow rate of the heat generating unit with high heat output and the heat generating unit with low heat output is the same. The coolant does not absorb enough heat and then exchanges heat through the heat exchanger. At the same time, the outdoor environment is not taken into consideration, and the energy utilization rate is low, which affects the cooling effect. Therefore, an immersion liquid cooling heat dissipation circulation control system is proposed. Summary of the invention

[0027] In this embodiment, specifically: S3 is to set an adaptive regulating valve in the outdoor heat dissipation unit pipe network subsystem, and the regulating valve can adjust the flow according to the liquid temperature on the electronic equipment deployment side to ensure the stability of the liquid temperature on the electronic equipment operation side.

[0029] Working principle: Since the traditional immersion liquid cooling control system adopts a quantitative flow rate, the flow rate for high and low heat generation is the same. The coolant does not absorb enough heat for heat exchange through the heat exchanger. At the same time, the outdoor environment is not taken into account, and the energy utilization rate is low, which affects the cooling effect. Therefore, the present invention can adopt adaptive variable flow regulation for both the electronic equipment deployment side flow and the outdoor heat dissipation liquid flow on the premise of fully considering the reasonable deployment of electronic equipment with different heat dissipation needs, so as to ensure the normal operation and extend the service life of electronic equipment with different heat generation, and at the same time improve energy utilization efficiency.
