Patent ID: 8654532

Claim:
A server cabinet suitable for accommodating at least one tray, each tray bearing at least one heat source and a heat exchanger disposed on the heat source, the server cabinet including a coolant distribution system comprising: a first coolant pipe, comprising: multiple tube bodies interconnected in series, wherein each of the tube bodies includes a first chamber and a second chamber and the first chamber and the second chamber are adjacent to and separated from each other, the second chambers of each of the two adjacent tube bodies are in communication with each other, each of the tube bodies has at least one connection port in communication with the first chamber, and the connection port is suitable for being connected to the heat exchanger; and at least one adjustable valve disposed in each of the tube bodies, wherein the first chamber in each of the tube bodies is in communication with the second chamber in the tube body through the adjustable valve; a second coolant pipe, suitable for being connected to the heat exchanger; and a cooling circulation power device, connected to the first coolant pipe and the second coolant pipe; wherein the cooling circulation power device is used to drive a cooling fluid to flow to and through the second chambers of the tube bodies of the first coolant pipe, and each adjustable valve is used to adjust the flow rate of the cooling fluid in the corresponding tube body flowing from the second chamber to the first chamber, so that the cooling fluid flows from the first chamber to the heat exchanger to perform heat exchange on the heat source and flows back to the cooling circulation power device through the second coolant pipe.
