In this embodiment, the liquid-blocking partition plate 51 is made of stainless steel; the elastic member 52 is an existing compression spring; the one-way flow valve 53 is a one-way valve commonly used in the art for liquid cooling heat dissipation.
In the actual heat dissipation process, the working process of the interactive management terminal in this embodiment is as follows: 1) the liquid circulating pump 33 drives the heat exchange liquid to circularly flow in the first flow path, and at the moment, the heat exchange liquid flowing through the liquid cooling plate 2 can take away heat generated by each device in the communication unit, so that heat dissipation of the interactive management terminal is realized; 2) the heat-exchange liquid continuously absorbs the heat generated by the communication unit to raise its temperature, the sealing bag 24 is continuously heated by the heat-exchange liquid until it is fully expanded to be able to block the conduction of the connection groove 23, so that the heat-exchange liquid cannot circulate in the first flow path, while the heat-exchange liquid is continuously accumulated in the liquid inlet tank 21 (the liquid circulating pump 33 is always working), the accumulation of the heat-exchange liquid continuously pushes the liquid-blocking partition plate 51 and the elastic member 52, so that the liquid-blocking partition plate 51 gradually slides in the direction away from the liquid inlet slot 21 until the liquid inlet pipeline 41 is completely communicated, so that the heat-exchange liquid can flow into the liquid cooler 43 through the extended liquid inlet line 41, at this time, the second flow path is conducted, the heat-exchange liquid flows in the second flow path, so that the temperature of the heat-exchange liquid is continuously reduced, meanwhile, heat generated by the communication unit can be better taken away, and heat dissipation of the interactive management terminal is realized; 3) when the temperature of the heat-exchange liquid is cooled to be low enough, the temperature of the sealing bag 24 can be reduced by the heat-exchange liquid until the sealing bag recovers to the contracted state, at this time, the first flow passage is conducted again, so that the liquid blocking partition plate 51 recovers to the position of blocking the liquid inlet pipeline 41 under the driving of the elastic member 52, the heat-exchange liquid circularly flows in the first flow passage, the heat generated by each device in the communication unit is taken away, the heat dissipation of the interactive management terminal is realized, and at this time, the liquid cooling unit stops working.
