Heat dissipation control method and immersion cooling system thereof

A heat dissipation control method applied to an immersion cooling apparatus for cooling a heat generating member, the immersion cooling apparatus comprising a cooling chamber, a pump and a fan device, the heat generating member being immersed in a cooling solution stored in the cooling chamber, the fan device cooling steam generated by the cooling solution into liquid when the cooling solution absorbs heat of the heat generating member, the pump being communicated with the cooling chamber and the fan device for transmitting the steam to the fan device and transmitting the cooling solution after being cooled to the cooling chamber, the heat dissipation control method comprising:

• initializing at least one cooling parameter during the immersion cooling apparatus is turned on;
• utilizing a sensing processor to detect a steam temperature in the cooling chamber;
• the sensing processor preferentially increasing power of the pump when determining the steam temperature is larger than a maximum of a temperature control range;
• and
• the sensing processor preferentially decreasing power of the fan device when determining the steam temperature is less than a minimum of the temperature control range.
