Computer system with a liquid-cooling thermal module having a plurality of pumps

[0014]Please refer to FIG. 2, which shows a block diagram of a computer system 30 according to the present invention. The computer system 30 comprises a processor 34 for processing data, a storage unit 36 for storing data, a cooling module 32 for expelling heat generated by the processor 34, and a detector 38. The cooling module 32 contains a pipe 42, a part of which is adjacent to the processor 34, for transferring heat, and a cooling device 44. The cooling device 44 comprises a plurality of tanks 46 connected serially, a plurality of pumps 48, a control unit 50, an aperture 52, a liquid-in port 54 and a liquid-out port 56. A first tank 46a (i.e. the tank with the liquid-in port 54) and a last tank 46b (i.e. the tank with the liquid-out port 56) are connected with the pipe 42 to form a closed loop. At least one pump is capable of being coupled to the plurality of tanks 46. Furthermore, the bottom of the last tank 46b is lower than that of other tanks 46. In this way, compared to th...
