Detailed Description
As shown in fig. 1 and 2, a backup power supply system 100 for a computing device according to one embodiment of the present application includes one or more heat sinks 152 in fluid communication in parallel or series. The heat sink 152 is mounted to the computing device in a heat-exchangeable manner, such as in an electronic component 154 that is mounted in the computing device and requires cooling to maintain proper operation. The flow conduit in fluid communication with the heat sink 152 includes a fluid inlet 112 for providing cooling fluid to the heat sink 152 and a fluid outlet 192 for collecting cooling fluid from the heat sink 152. The refrigeration unit 50 is in fluid communication with the inlet 112 and outlet 192 via the main supply line 110 and the main return line 190, respectively, to form a circulating refrigeration system for continuously supplying the low temperature coolant 52 to the heat sink 152 and for recovering the high temperature coolant 54 from the heat sink 152. The liquid inlet 112 and the liquid outlet 192 are respectively communicated with the main liquid supply pipe 110 and the main liquid return pipe 190 in the form of branch pipes.
The backup power supply system 100 includes a first hydro-generator 132 and a rechargeable battery 142. The first hydro-generator 132 may be a hydro-generator sized to produce a maximum voltage of 80 volts and a maximum current of 220 milliamps at a flow rate of 25 liters per minute, for example, at a flow pressure of 0.5 bar (bar). The first hydro-generator 132 is in fluid communication between the inlet 112 and the heat sink 152. The rechargeable battery 142 is electrically connected to the first power output 134 of the first hydro-generator 132. The coolant 51 flowing from the fluid inlet 112 to the heat sink 152 drives the first hydro-generator 132 to operate and generate electricity. The electric power output by the first hydro-generator 132 is provided to the rechargeable battery 142 through the first electric power output 134 such that the rechargeable battery 142 is charged by the first hydro-generator 132.
Alternatively or additionally, the rechargeable battery 142 also has an external power interface 144 such that the rechargeable battery 142 may be charged by an external power source, such as by municipal power supply, through the external power interface 144. The backup power supply system 100 also includes a charge controller 162. The charge controller 162 is electrically connected to the first hydro-generator 132, the external power interface 144, and the rechargeable battery 142 such that the rechargeable battery 142 may optionally be charged by the first hydro-generator 132 and/or through the external power interface 144. For example, the charging controller 162 may be configured to cause the rechargeable battery 142 to be charged together by the municipal power and the first hydro-generator 142 through the external power interface 144 when the power capacity of the rechargeable battery 142 is below a preset value, for example, when the power capacity of the rechargeable battery 142 is below 80%, so as to accelerate the charging process of the rechargeable battery 142. When the power capacity of the rechargeable battery 142 reaches a preset value, for example, 80%, the charging controller 162 switches the charging mode such that the rechargeable battery 142 is charged only by the first hydro-generator 132, thereby achieving the effect of saving municipal power supply by using the electric energy generated by the first hydro-generator 132.
Alternatively or additionally, the backup power system 100 also includes a second hydro-generator 172 in fluid communication between the fluid outlet 192 and the heat sink 152. The second hydro-generator 172 may be the same size hydro-generator as the first hydro-generator 132. The second power output 174 of the second hydro-generator 172 is electrically connected to the rechargeable battery 142. The coolant 59 flowing from the heat sink 152 to the liquid outlet 192 drives the second hydro-generator 172 to operate and generate electricity. The electric power output from the second hydro-generator 172 is supplied to the rechargeable battery 142 through the second electric power output 174, so that the rechargeable battery 142 is charged by the second hydro-generator 172.
Alternatively or additionally, the rechargeable battery 142 has an external power interface 144 such that the rechargeable battery 142 may be charged by the external power source 70 through the external power interface 144, such as powered by municipal power.
The backup power supply system 100 may also include a charge controller 162.

For example, the charge controller 162 may be configured to cause the rechargeable battery 142 to be charged with municipal power through the external power interface 144 to expedite charging of the rechargeable battery 142 when the power capacity of the rechargeable battery 142 is below a preset value, such as when the power capacity of the rechargeable battery 142 is below 80%. When the power capacity of the rechargeable battery 142 reaches a preset value, for example, 80%, the charging controller 162 switches the charging mode to charge the rechargeable battery 142 by the first hydroelectric generator 132 and the second hydroelectric generator 172, so that the effect of saving municipal power supply is achieved by utilizing the electric energy generated by the first hydroelectric generator 132.
