Abstract

The present invention discloses a flat mini pump which is applied on fluid transporting, the mini pump comprises a main body, a rotor and a stator, wherein the includes a cover and a bottom; a combination surface between the cover and the bottom is provided with a leakage proof apparatus, and the inside of the main body forms a cavity with a inlet and an outlet; the rotor is set inside the cavity and includes a magnet group, a impeller wheel and a axis core, wherein the magnet group is connected on one side of the impeller wheel and rotate coaxially with the impeller wheel through axis core location; the stator is set inside the cavity and include a plurality of coil assemblies in axial direction corresponding to the magnet group, wherein the coil assemblies generate a axial magnetic field with the magnet group to drive the impeller wheel rotate so as to convey the fluid from the inlet to the outlet. The plat mini pump provided in the invention adopts axial magnetic field design, which can minimize volume, enhance rotate torsion force, outlet pressure and heat yield performance of the pump.

Description

technical field [0001] The invention relates to a flat micropump, in particular to a flat micropump designed with an axial magnetic field, which has the advantages of miniaturized volume, high rotational torque, high outlet pressure and good heat dissipation. Background technique [0002] Whether it is used in water-cooled heat dissipation systems, fuel delivery devices in fuel cells, or artificial hearts, micropumps are very important components and play a very critical role. Therefore, designing and manufacturing a micropump with good sealing performance, high rotational torque, high fluid outlet pressure and good motor cooling capacity has become the goal pursued by designers and manufacturers. [0003] The structure of the centrifugal pump generates a magnetic field through the input current of the coil on the stator, and generates a magnetic force with the magnet on the rotor to drive the impeller to rotate and make the fluid flow. According to the motor setting method...
