Description

Liquid-cooled heat dissipation system and its pump

The present invention relates to a pump and a liquid-cooled heat dissipation system for driving liquid to flow, in particular to a pump in which non-conductive liquid can circulate, and a liquid-cooled heat dissipation system with the pump.

Please refer to FIG. 1, which is a conventional pump 9. The conventional pump 9 has a housing 91, a rotor group 92 and a stator group 93. The housing 91 is formed by a combination of a housing 911 and a housing cover 912, and a diversion space 913 is formed between the interior of the housing 911 and the housing cover 912. The housing 91 further has an input port 914 and an output port 915 communicating with the diversion space 913, and the bottom end of the housing 911 has a shaft connection portion 916. The rotor assembly 92 is located in the diversion space 913. The rotor assembly 92 has an impeller 921 rotatably disposed on the shaft connection portion 916, and a magnet ring 922 is coupled with the impeller 921 and is located on the outer periphery of the shaft connection portion 916. The stator assembly 93 is combined with the shell base 911 and is located outside the diversion space 913, and the stator assembly 93 is diametrically opposed to the magnet ring 922 with the shell base 911 interposed therebetween. When the conventional pump 9 is operating, the magnetic field generated by the stator assembly 93 can penetrate the housing 911 and magnetically repel the magnet ring 922, thereby driving the impeller 921 to rotate, so that liquid can pass through the input port 914 It flows into the diversion space 913, and is guided and discharged from the output port 915. An embodiment similar to the conventional pump 9 has been disclosed in the Republic of China Patent Publication No. 587784.

However, in the above-mentioned conventional pump 9, since the pump 9 relies on electric power to drive the impeller 921 to rotate, an outlet hole is usually opened in the housing 911 so that a wire of the stator assembly 93 passes through the outlet hole. And connect an external power supply, and then use a sealing material to coat the periphery of the outlet hole to prevent liquid leakage, and the use of too much sealing material will affect the volume of the entire housing 91, or too little will also cause the output It is difficult to completely seal the wire hole. If the relevant leak-proof facilities are not prepared at the outlet hole, it is easy to cause the liquid to leak out of the casing 91; especially for the smaller pump 9, its leakage prevention space is smaller. It is difficult to prevent leakage in a limited space, which further affects the driving efficiency of the pump 9.

In view of this, the conventional pump does still have to be improved.

In order to solve the above-mentioned problems, the object of the present invention is to provide a liquid-cooled heat dissipation system and its pump, which can avoid the leakage of working fluid in a housing.

The second objective of the present invention is to provide a liquid-cooled heat dissipation system and its pump, which can reduce the thickness of the overall shell.
