[0037] Refer to Figures 1 to 8 , the working principle of the liquid-cooled radiator cold head for synchronously cooling the CPU and the memory in this embodiment is as follows:

[0038] When the entire cold head body 1 is installed on the CPU of the computer main board, the heat sink 131 of the cold head body 1 fits the CPU. The water pump 13 extracts the coolant in the water-cooled radiator 4 and makes the coolant continuously circulate between the water-cooled radiator 4 and the water pump 13, taking away the heat on the CPU and cooling through the water-cooled radiator 4;

[0039] When the fan 2 is fixedly installed on the side surface of the housing 11 through a plurality of locking screws 3, all the probes 241 are inserted into all the jacks 161 one by one and are elastically contacted and electrically connected to all the contacts one by one. Since the fan blades 22 of the fan 2 and the display screen 14 are on the same horizontal plane, therefore, the fan blades 22 are aligned with the electronic components and the memory beside the CPU of the computer main board at this time. The main board 121 controls the rotation of the fan blades 22 through the first circuit board 18 and the second circuit board 24. The air flow generated by the fan blades 22 can directly blow to the electronic components and the memory beside the CPU, so as to dissipate heat and remove dust from the electronic components and the memory beside the CPU.

[0040] Embodiment 2

[0041] Refer to Figures 8 to 10, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment lies in that the specific connection manner between the fan 2 and the cold head body 1 is different. In this embodiment, the fan 2 is snap-connected to the side wall of the cold head body 1. Specifically, two elongated hanging portions 5 are provided at intervals on the outer wall of the housing 11 of the cold head body 1. A slot 51 is formed by hollowing out the inner side wall and the top of each hanging portion 5. The lower end of the fan 2 and the contact electrical connection part of the cold head body 1 (i.e., the first circuit board 18 and each contact thereon) are both located between the two hanging portions 5. Longitudinal insertion platforms 6 are respectively provided on the two opposite sides of the lower end of the fan 2. The two insertion platforms 6 are respectively inserted into the two slots 51 one by one to realize the mutual snap connection between the fan 2 and the cold head body 1. In this embodiment, the two hanging portions 5 are integrally formed with the housing 11, and the two insertion platforms 6 are located on the left and right sides of the fixing base 211 and are integrally formed with the fixing base 211. Other structures and working principles are the same as those of the first embodiment and will not be elaborated here.
