Water-cooling thermal dissipating method

A water-cooling thermal dissipating method configured for cooling a heat generating element inside an electronic device through a cooling liquid in a tank by controlling at least one of a fan placed at a thermal exchanger, by a fan controller, a pump, by a pump controller, and a throttle valve, by a throttle valve controller, of a thermal cycling loop connected through a plurality of pipes, the method comprising the steps of:

• (a) performing a self-condition inspection by a microprocessor, connected to the fan controller, the pump controller, the throttle valve controller, a cooling liquid sensor, and a thermal sensor, in a controlling module,
• (b) detecting whether a working temperature of the cooling liquid, by the cooling liquid sensor, is greater than a first predetermined temperature, and detecting whether a working temperature of the heat generating element, by the thermal sensor, is greater than a second predetermined temperature,
• (c) outputting a shutdown warning signal, by the cooling liquid sensor, if the working temperature of the cooling liquid is greater than the first predetermined temperature and a liquid level of the cooling liquid sensed by the cooling liquid sensor, is not lower than a threshold liquid level, and outputting a warning signal, by the thermal sensor, if the working temperature of the heat generating element is greater than the second predetermined temperature,
• (c1) displaying the shutdown warning signal if the working temperature of the cooling liquid is greater than the first predetermined temperature and the liquid level of the cooling liquid is lower than the threshold liquid level,
• (c2) compulsory shutting down the electronic device after a delay shutdown time, and
• (d) displaying the warning signal of the thermal sensor.
