Water supply structure of liquid cooling device, pump having water supply structure and liquid cooling device having water supply structure

A pump having a water supply structure, comprising:

• a pump provided with an inlet;
• and
• a water supply structure disposed on the pump, the water supply structure comprising:
• a lower lid in which an outlet is disposed, wherein the outlet communicates with the inlet of the pump;
• an upper lid combined on the lower lid, wherein a chamber is formed between the lower lid and the upper lid, wherein the lower lid has a connection hole combined with the upper lid, wherein the chamber communicates with the outlet of the lower lid and accommodates a coolant;
• and
• a pressure control member disposed moveable in the chamber of the upper lid, wherein the pressure control member comprises a piston and an elastic part controlling the piston to move inside the chamber, wherein the elastic part pushes against the piston to move inside the chamber such that the coolant is injected into the pump until hydraulic pressure equilibrium is achieved.

A liquid cooling device having a water supply structure, comprising a water block, a pump, a cooling module, a liquid reservoir, a plurality of pipes which are connected among the water block, the pump, the cooling module, and the liquid reservoir, and a water supply structure;

• the water supply structure comprising:
• a lower lid in which an outlet is disposed, wherein the outlet communicates with an interior of the liquid cooling device;
• an upper lid combined on the lower lid, wherein a chamber is formed between the lower lid and the upper lid, wherein the chamber communicates with the outlet of the lower lid and accommodates a coolant;
• and
• a pressure control member disposed moveable in the chamber of the upper lid and dividing the chamber into an upper chamber allowing an air access and a lower chamber which is enclosed to accommodate the coolant, wherein the upper lid comprises an air hole communicating with the upper chamber, wherein the pressure control member comprises a piston and an elastic part controlling the piston to move inside the chamber, wherein the elastic part pushes against the piston to move inside the chamber such that the coolant is injected into the liquid cooling device through the outlet until hydraulic pressure equilibrium is achieved.

A cooling module having a water supply structure, comprising:

• a cooling module;
• and
• a water supply structure disposed on the cooling module and comprising:
• a lower lid in which an outlet is disposed, wherein the outlet communicates with an interior of the cooling module;
• an upper lid combined on the lower lid, wherein a chamber is formed between the lower lid and the upper lid, wherein the chamber communicates with the outlet of the lower lid and accommodates a coolant;
• and
• a pressure control member disposed movable in the chamber of the upper lid and dividing the chamber into an upper chamber allowing an air access and a lower chamber which is enclosed to accommodate the coolant, wherein the pressure control member comprises a piston and an elastic part controlling the piston to move inside the chamber, wherein the elastic part pushes against the piston to move inside the chamber such that the coolant is injected into the cooling module through the outlet until hydraulic pressure equilibrium is achieved.
