Abstract
A cooling liquid flow control device includes a heat dissipation bottom plate, a fixing holder, a cooling module, and a temperature control element. The heat dissipation bottom plate has a bottom surface configured to be in contact with a heating element on a substrate. The fixing holder is connected to the heat dissipation bottom plate and configured to be fixed with the substrate. The cooling module is connected to a top surface of the heat dissipation bottom plate to form a cavity. The cavity is configured to circulate a cooling liquid. The temperature control element is disposed in the cavity and is configured to deform based on a temperature of the cooling liquid in the cavity, thereby adjusting a flow rate of the cooling liquid in and out of the cavity.
Claims10
A cooling liquid flow control device, comprising:
- a heat dissipation bottom plate comprising a bottom surface configured to be in contact with 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 configured to circulate a cooling liquid;
- a temperature control element disposed in the cavity and configured to deform based on a temperature of the cooling liquid in the cavity, thereby adjusting a flow rate of the cooling liquid in and out of the cavity;
- and
- a pressing block extends from a top plate of the cooling module and configured to press against the temperature control element disposed in the cavity.
Wherein the cooling module further comprises:
- the top plate having a liquid inlet hole and a liquid outlet hole, wherein the liquid inlet hole connects the liquid inlet pipe and the first sub-cavity, and the liquid outlet hole connects the liquid outlet pipe and the second sub-cavity;
- an outer surrounding wall extending vertically from an edge of the top plate and surrounding the edge of the top plate, wherein the outer surrounding wall is connected to the heat dissipation bottom plate;
- and
- an inner surrounding wall extending vertically from the top plate and surrounded by the outer surrounding wall, wherein the inner surrounding wall is connected to the heat dissipation bottom plate.
