Title: Water block of double-layered radiating water-cooling radiator

Description:
FIELD OF TECHNOLOGY 
     The present invention relates to the technical field of water-cooling radiators of computer CPUs, in particular to a water block of a double-layered radiating water-cooling radiator. 
     BACKGROUND 
     It is well known that integrated circuits in a computer will generate plenty of heat, which will lead to unstable operation and shortened service life of a system, and is even likely to burn some components. Therefore, it is necessary to arrange a radiator to absorb the heat so as to guarantee normal temperatures of the components of the computer. 
     However, a liquid-cooling radiator generally used for radiation of a computer CPU performs radiation by means of circulation of a cooling liquid. The cooling liquid will take away heat at a heating end and release the heat at a radiating end, thereby achieving a radiating purpose. 
     A whole device in an existing scheme includes a water block, a pipeline and a radiating bar and the like. Driven by a water pump in the water block, the cooling liquid flows through assemblies such as the water block, the pipeline and the radiating bar in sequence. The device is matched with water blocks and radiating bars of different specifications according to radiating requirements. The radiating capacity is dependent on the radiating area of the radiating bar, and the larger the area is, the better the radiating capacity is. 
     However, subject to compatibility, in the existing scheme, the size of the radiating bar is often limited by the size of a case and arrangement of an installation site, and the radiating capacity of the system is limited by the size of the radiating bar. 
     Information disclosed in this background art is merely intended to enhance understanding of the general background of the present invention and shall not be taken as an acknowledgment or any form of suggestion that this information forms the prior art already known to those of ordinary skill in the art.
