This application relates to an integrated intelligent temperature control and heat dissipation system for a prefabricated box-type substation, belonging to the field of power equipment heat dissipation technology. The system includes a base 1 and a housing 2 mounted on the base 1. The housing 2 is divided into a low-pressure chamber, a transformer chamber, and a high-pressure chamber. The transformer chamber is equipped with an integrated cooling unit 4 connected to a closed-loop temperature control system. The system also includes an intelligent control unit 9. The closed-loop temperature control system includes a cooling plate 5, a heat exchange unit 6, a circulating pump 7, an expansion tank 14, a water replenishment device 15, and an optional plate heat exchanger 8. The intelligent control unit 9 is equipped with a load feedforward-temperature feedback dual-mode predictive controller. This controller embeds a lightweight LSTM model. Input variables include the transformer primary current harmonic distortion rate (THD), the active power change rate (dP / dt), the winding temperature rise history curve measured by distributed optical fiber, and the cooling water inlet and outlet temperature difference (ΔT). The output is the target flow increment (ΔQ) of each cooling chamber within the next 60 seconds and the pre-speed command of the heat exchange fan. This application can solve the problem of control response lag caused by the thermal inertia of the cooling medium and improve the thermal response capability of the transformer under sudden short-term overload conditions.

The present application relates to a kind of data center immersion liquid cooling systems based on adaptive coating, comprising: outdoor cold supply unit, room side air cooling unit and rack side immersion cooling unit;Rack side immersion cooling unit includes: rack, mainboard, adaptive coating, liquid cooling plate, thermoluminescent material, heat exchanger one and heat exchanger two;Data center includes multiple racks, mainboard is immersed in cooling working medium in rack, cooling working medium is condensed on the surface of liquid cooling plate after temperature rise, and condensed liquid working medium is re-dropped back to pool to carry out liquid supplement, after heat is taken away by liquid cooling plate, cooling working medium flows into heat exchanger one below thermoluminescent material, so that thermoluminescent material emits visible light or ultraviolet light, to be irradiated on the adaptive coating on the surface of mainboard.Compared with prior art, the present application can simultaneously adjust its characteristics according to different stages of boiling, improve cooling capacity;It can improve the energy utilization efficiency of immersion cooling system.
