Abstract: The present invention belongs to the technical field of liquid-cooling heat dissipation, wherein discloses a novel mechanical pump liquid-cooling heat dissipation system, comprising an external radiator, a circulating pipe and a mechanical pump, wherein the circulating pipe communicates the external radiator with the circulating pipe to form a circulation loop, the mechanical pump includes a volute in the form of a hollow cylinder, a fixing surface is formed at one end of the volute, the fixing surface is planar and is part of the outer surface of the volute, a layer of heat-conducting silicone grease is coated on the fixing surface, the fixing surface and a heat source are fixed through pressure lamination, and the heat-conducting silicone grease is attached to the fixing surface and the heat source; and the mechanical pump takes away heat of the heat source and transfers it to a cooling working medium while pumping the cooling working medium to circulate in the circulation loop.

Abstract: A micro-hydraulic suspension mechanical pump includes a volute, an upper cover, an impeller, a brushless motor, a waterproof sleeve and water lubrication spiral groove thrust bearings, each having stationary and rotating rings. A water inlet and a water outlet channel are provided on the volute, and a middle water inlet hole is formed on the upper cover. The water lubrication spiral groove thrust bearings are provided above and below a magnetic steel rotor. During operation of the micro-hydraulic suspension mechanical pump, a liquid film is formed between the stationary ring and the rotating ring to enable the magnetic steel rotor to be suspended, and a liquid film is formed between the outer wall of the rotor sleeve and the inner wall of the waterproof sleeve. Due to suspension of the rotor, wear caused contact is avoided, and service life of the micromechanical pump is improved.
