Claim 0:
1. A cooling liquid flow control device, comprising:
a heat dissipation bottom plate having a bottom surface configured to be in contact with a heating element on a substrate;
a holder connected to the heat dissipation bottom plate and configured to be fixed with the substrate;
a cooling module comprising a liquid inlet pipe and a liquid outlet pipe with a cooling liquid flowing inside and connected to a top surface of the heat dissipation bottom plate to form a cavity, the cavity being configured to circulate the cooling liquid and further comprising:
a first sub-cavity configured to receive the cooling liquid from the liquid inlet pipe; and
a second sub-cavity configured to deliver the cooling liquid from the first sub-cavity to the liquid outlet pipe; and

a temperature controller connected to the cooling module, comprising:
a valve, the valve being configured to reciprocally move based on a temperature of the heating element, thereby adjusting a flow rate of the cooling liquid in and out of the cavity; and
a chamber body configured to accommodate the cooling liquid from the first sub-cavity, and wherein the chamber body comprising:
a liquid inlet area configured to receive the cooling liquid from the first sub-cavity;
a liquid outlet area configured to deliver the cooling liquid from the liquid inlet area to the second sub-cavity; and
a spacer separating the liquid inlet area and the liquid outlet area and having an opening to enable the cooling liquid to circulate between the liquid inlet area and the liquid outlet area,

wherein the valve is configured to clog and be separated from the opening.
