Cooling liquid flow control device

A cooling liquid flow control device, comprising:

• a heat dissipation bottom plate having a bottom surface configured to be in contact with a chipset serving as a heating element on a substrate;
• a fixing holder connected to the heat dissipation bottom plate and configured to be fixed with the substrate;
• a cooling module connected to a top surface of the heat dissipation bottom plate to form a cavity, the cavity being configured to circulate a cooling liquid, the cavity further comprising a first sub-cavity and a second sub-cavity;
• and
• a temperature control element connected to the cooling module and comprising:
• a chamber body configured to accommodate the cooling liquid from the first sub-cavity;
• an actuator close to the chamber body;
• and
• a valve connected to the actuator configured to actuate the valve, wherein the valve is configured to rotate based on a temperature of the heating element, thereby adjusting a flow rate of the cooling liquid in and out of the cavity.
