[embodiment]
Please refer to Figure 1 and Figure 2, liquid-cooled radiating system micropump of the present invention comprises that a housing 1, is assembled in an impeller sets 2 and the driver element 3 in the housing 1, and wherein this impeller sets 2 is driven by this driver element 3 and rotates.
Housing 1 comprises the body 11 of a hollow and loam cake 10 and the lower cover 19 that fastens with this body 11.This upper and lower cover 10,19 cooperates with the top 101 of this body 11 and bottom 102 respectively and is assembled into one.Be provided with a seal ring 108 between the top 101 of this loam cake 10 and this body 11, thereby prevent the working liquid body leakage.The lower end of this loam cake 10 is provided with the annular groove 106 that matches with sealing circle 108.This loam cake 10 also is provided with a feed liquor port 104.
Be provided with a baffle plate 14 in the body 11, thereby in this body 11, form a upper chamber 15 and a lower chamber 18.These body 11 outer fluid ports 110 that are communicated with this upper chamber 15 that are provided with.
As shown in Figure 3, be provided with a dividing plate 12 in the upper chamber 15 of this body 11, thereby this dividing plate 12 is divided into first cavity volume 16 and second cavity volume 17 with this upper chamber 15, promptly forms first cavity volume 16 between this dividing plate 12 and the loam cake 10, forms second cavity volume 17 between dividing plate 12 and the baffle plate 14.This first cavity volume 16 is communicated with feed liquor port 104, and this second cavity volume 17 is communicated with fluid port 110.These dividing plate 12 central authorities also are provided with a positioning hole 120 and are located on this positioning hole 120 through hole 122 all around, thereby this first cavity volume 16 is communicated with this second cavity volume 17.
Impeller sets 2 places in second cavity volume 17, comprise that a rotating shaft 20, is sheathed on the outer impeller 26 of this bearing 22 with bearing 22 and that this rotating shaft 20 rotatably is connected, these impeller 26 peripheries are provided with some blades, are appreciated that ground, and this bearing 22 also can form with these impeller 26 one.These rotating shaft 20 upper ends are positioned in the positioning hole 120 of this dividing plate 12, and the lower end is connected on the dividing plate 14, and these dividing plate 14 central authorities are provided with an axle bed 140 of accommodating these rotating shaft 20 lower ends.These rotating shaft 20 two ends also are respectively equipped with one and limit the clasp 24 that this rotating shaft 20 is moved in the axial direction.
Be provided with first permanent magnet 260 in the impeller 26, this first permanent magnet 260 is flat, annular, along the circumferential direction is magnetized to the some staggered N utmost point and S utmost points of being.
Driver element 3 places the bottom of housing 1, promptly is positioned at lower chamber 18, and it comprises a motor, and this motor comprises the circuit board 31 that a rotor 34 and this rotor 34 of a control rotate.
During work, driver element 3 drives this rotor 34 rotations, and then promote 340 rotations of this second permanent magnet, because the action of a magnetic field power, further promote 260 rotations of first permanent magnet, thereby impeller 26 is with 260 rotations of this first permanent magnet, and the liquid that pushes the work forward circulates in this liquid-cooled radiating system, and then to system radiating.
