New description: [New technical field] The present invention relates to a heat dissipating device, in particular to a liquid cooling heat dissipating device. [Prior Art] The electronic device achieves a predetermined function by the operation of a plurality of integrated circuit chips that are internally mounted. If the integrated circuit chip is used for a long time or the clock rate is high. In the use case, heat is generated to increase the temperature of the integrated circuit chip itself, but the high temperature affects the working efficiency of the integrated circuit chip, so that the speed of the electronic instrument becomes very slow, even a near fault condition occurs, and Since these integrated circuit chips are extremely delicate parts, in the high temperature environment, the electronic equipment may be burned, so that the electronic equipment that is used in the fine and expensive electronic equipment is provided with heat dissipation on the integrated circuit chip. The device avoids the phenomenon that the temperature of the integrated circuit chip is too high. The common heat dissipating device includes an air-cooled heat dissipating device and a liquid-cooled heat dissipating device. The air-cooling heat dissipating device uses a fan to rotate to drive the airflow through the integrated circuit chip. The effect of airflow convection can take away the heat that the wafers emit lightly. The liquid-cooled heat sink generally has to be installed in the integrated circuit. The fins on the chip are generally made of a metal material, and the heat of the wafers is first conducted, and the heat is contacted by the coolant to absorb the heat of the heat sink. The liquid-cooled heat dissipating device is used to drive the flow of the cooling liquid to enhance the heat dissipating effect. A liquid-cooling heat dissipating device 8 of the prior art is disclosed in the Chinese Patent Publication No. 587784. A base 8 j, a fan 82, a driving member 83' and a cover 84, the base 81 and the cover 84 cooperate to define a flow space. The fan 82 is disposed in the flow space The base 81 has a bottom wall 813, a surrounding wall 814 extending upward from the periphery of the bottom wall 813, a fixed shaft tube 815 disposed on the bottom wall 813, and four are symmetrically formed on the bottom wall 813. a receiving portion $16 on the outer bottom surface, an input tube 817 formed on the surrounding wall 814, and another output tube 818 formed on the surrounding wall 814. Each receiving portion 816 can be defined a chamber space and not isolated from the flow space isolation The fan 82 is disposed on the fixed shaft tube 815, and has a blade body 822 pivotally disposed on the fixed shaft tube 815, and a magnet ring surrounding the periphery of the blade body 822. 821. The blade body 822 has a plurality of blades 8221, and the magnet ring 821 is sleeved on the outer edge of the blades 8221. The driving member 83 can be energized to induce the magnet ring 821 to drive the fan 82 to rotate. The cooling liquid flows into the liquid flow space from the input pipe 817 and is discharged to the outside by the output pipe 818. The driving member 83 includes four stators ′ for the dedicated sub-coils 8 3 1 respectively disposed in the corresponding accommodating portions 816 The liquid of the field enters the liquid flow door through the input pipe 8丨7 on the base 8 and does not seep into the space of the chamber, and the four-stator coil 831 naturally does not ring. When the four stator coils 831 are energized, a magnetic field is generated, and the magnetic wires are magnetically permeable to the magnetic ring 821 of the fan 82 through the base 81, thereby pushing the fan 82 to rotate, and driving the coolant from the base 8i. The upper wheel outlet pipe 818 is discharged. However, the conventional heat dissipating device 8 needs to have a plurality of accommodating portions 816 that are not in communication with the liquid flow space, and the four stator coils are respectively disposed inside the accommodating portion 816 to form a heat dissipating device 8 . Good waterproof knot. However, this type of design requires four stator coils 831 to be assembled during assembly. The assembly is relatively complicated and the assembly efficiency is low. The four stator coils 831 also increase the product cost, which makes the profit of the product difficult to improve. * Furthermore, since the four stator coils 831 must be respectively mounted on the corresponding P 816 Θ, it is inconvenient for the connection of the θ海四 stator coil 831. In addition, the guest Jinqiu s ^ 今 邛 邛 816 are not connected to each other and dispersed away from 'the stator coil 831 is energized, the power of the 玍 比较 can not be close to form a magnetic circuit, thus forming electromagnetic power The disadvantage of loss. [New content] Therefore, the purpose of the present invention is to provide a liquid-cooled heat sink that can be easily assembled and can reduce electromagnetic power loss. = Yes, the new liquid-cooled heat sink is suitable for driving - cooling liquid fast & moving, and includes a shell, a - drive Syria "sealing, a fan and a shouting seat including a top wall, - by The inner edge of the top wall extends inwardly and downwardly around the wall, and - an outer surrounding niche extending downward from the outer edge of the top wall

The top cover 4 is engageable with the top wall u and cooperates with the top wall u and the inner surrounding wall 12 to define a flow space 4丨. The top cover 4 includes at least two liquid flow holes 42 communicating with the outside and the liquid flow space 41, and a second fitting groove 43 formed on the lower periphery of the top cover 4. M290366 The bottom cover 5 can be combined with the lower half of the outer surrounding wall 13 of the housing 1 and cooperate with the outer surrounding wall 13, the top wall 11 and the inner surrounding wall 12 to define an accommodating space 51. The accommodating space 51 is not in communication with the liquid flow space 41. The fan 2 is accommodated in the liquid flow space 41, and the coolant can be caused to flow from one liquid flow hole 42 and flow out from the other liquid flow hole 42. The driving member 3 is disposed in the accommodating space 51, and can drive the fan 2 to rotate to drive the cooling liquid to flow into the liquid flow space 41 from the liquid flow hole 42 and then flow out to the outside through the other liquid flow hole 42. The second fitting groove 43 of the top cover 4 can be correspondingly engaged with the second fitting 15 of the top wall 11 and cooperate with each other to define a second fitting space 431.
