Description

Technical Field

[0001] The invention belongs to the field of fluid power and micro-manufacturing, and in particular relates to a hurricane-shaped electric fluid power pump. Background Art

[0002] In the field of microelectronic heat dissipation, research has found that forced convection of the working fluid in a microchannel heat sink can significantly improve the heat dissipation effect. Liquid working fluids will produce a very high flow pressure difference in the microchannel structure, so conventional fluid driving methods are not feasible in microchannels. This requires a working fluid driver that does not increase the volume of the heat sink and can work stably to provide sufficient fluid outlet pressure as a power source for the flow of working fluid. Traditional mechanical pumps have the disadvantages of large size, high power consumption, high noise, and inaccurate flow control.

[0003] The patent with application number CN201620880937.7 discloses a cylindrical electrofluidic micropump, including a cylindrical pump casing and an electrode array arranged therein; the electrode array includes a cathode and an anode spaced apart from each other; the electrode array is rolled into an elastic cylindrical structure and fits tightly with the inner wall of the cylindrical pump casing; the electrode array is fixed axially and radially by the friction between the electrode array and the inner wall of the cylindrical pump casing.

[0004] The dielectric liquid subjected to a high voltage electric field will form positively and negatively charged ions. The positive and negative ions are attracted by the corresponding electrodes and attach to the corresponding electrodes, thus generating a flow direction.

[0005] Patent application number CN201620880937.7, the electrode in the patent is cylindrical, and the suction force of the cylindrical electrode is small, so the electrode in the patent is only suitable for some occasions where the flow rate of dielectric liquid is large and the flow rate is slow;

[0006] Patent application number CN201620880937.7, the electrode sheet is composed of a cathode and an anode, and they are spaced apart and staggered. The cathode and anode of the electrode sheet are staggered. In this staggered form, the electrodes are located on a cylindrical surface. From the cross-section, a large through hole has only one annular electrode. The pulling force of the electric fluid on the medium is small, especially for the medium in the center. This electric fluid pump inlet and outlet will not produce a relatively large pressure difference, resulting in a slow flow rate.

[0007] Moreover, the fluid medium includes not only liquid but also gas. The patent with application number CN201620880937.7 does not process the gas in the medium, but in fact, the less gas in the dielectric liquid, the better, and it is best to liquefy all of it into liquid to meet the flow demand, and the electrodes of the entire cylindrical pump casing cannot be accelerated step by step, and the flow rate in the entire device remains uniform. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a hurricane-shaped electrofluidic pump to solve the problems that the existing electrode sheets are arranged in only one large circle, the flow rate is slow, and the flow rate in the entire cylindrical pump housing cannot be increased step by step.

[0009] The present invention is achieved through the following technical solutions.

[0010] A hurricane-shaped electrofluidic pump comprises an upper electrode module and a lower electrode module, wherein the upper electrode module comprises a double layer of positive and negative electrodes, wherein the positive and negative electrodes of each layer are on the same plane and are separated by an isolation zone, and the positive and negative electrodes are in a spiral shape, wherein the positive electrode of the upper electrode module is on the inner side, and the negative electrode of the upper electrode module is on the outer side, and the lower electrode module also comprises a double layer of positive and negative electrodes, wherein the positive and negative electrodes of each layer are on the same plane and are separated by an isolation zone, and the positive and negative electrodes are in a spiral shape, wherein the spiral center of the upper electrode module and the spiral center of the lower electrode module are on the same vertical line, the positive electrode of the lower electrode module is on the outer side, and the negative electrode of the lower electrode module is on the inner side, and an upper electrode module and a lower electrode module are matched to form an electrode unit, and the hurricane-shaped electrofluidic pump is composed of a plurality of electrode units arranged in sequence from top to bottom with the upper electrode module facing upward. The double-layer electrode module is better than the single-layer electrode module. The layers can generate both spirally decreasing hurricane-shaped vortices and spirally increasing hurricane-shaped vortices, which increase the force on the medium and are suitable for use in environments with high flow rates.

[0011] Preferably, the double-layer positive electrode and negative electrode are separated by a separation region between the upper and lower layers.

[0012] Preferably, an electrode module substrate is further disposed below the upper electrode module and the lower electrode module, the outer circle of the electrode module substrate of the upper electrode module is provided with a liquid outlet A, and the center of the electrode module substrate of the lower row is provided with a liquid outlet B, so as to achieve physical gas-liquid separation.

[0013] Preferably, the width ratio of the positive electrode to the negative electrode is 3: 1. It is actually only the positive electrode that generates the pulling force, so the larger the area, the greater the pulling force, while the negative electrode only plays the role of ionizing the medium, does not generate a positive pulling force, but generates a reverse pulling force, so the area should be as small as possible to reduce the reverse pulling force. As for the ratio of 3: 1, it is a more reasonable solution obtained by experiment.

[0014] Preferably, the width ratio of the isolation region to the negative electrode is 1: 1. According to design calculations and experimental verification, the ratio of the isolation region to the negative electrode width is 1: 1, which is the best. When high-voltage direct current is applied between the positive and negative electrodes, the maximum ionization effect of the medium can be achieved without breakdown and arcing.

[0015] Preferably, a protruding edge is integrally formed on the electrode module substrate to form a small cavity, which facilitates radial movement of the medium.

[0016] Preferably, the upper and lower surfaces of the electrode module substrate are respectively provided with large spiral grooves and small spiral grooves, and the upper and lower surfaces are respectively used to place a single layer of positive electrodes and negative electrodes, the large spiral grooves of the upper electrode module are used to place positive electrodes, and the small spiral grooves are used to place negative electrodes, and the large spiral grooves of the lower electrode module are used to place negative electrodes, and the small spiral grooves are used to place positive electrodes. The electrode module substrate is placed in coordination with the upper and lower layers of positive and negative electrodes to reduce the space of the entire device.

[0017] Preferably, the depth of the large spiral groove and the small spiral groove accounts for one fifth of the thickness of the electrode module substrate.

[0018] Preferably, the outer ring of the electrode module substrate of the upper electrode module is provided with a liquid outlet A. If too many liquid outlets are provided at once, it is difficult to form a spiral hurricane.

[0019] Preferably, the same supply electrode is used between multiple upper electrode modules, and the outermost ends are connected by two wires located on the same side. The same supply electrode is used between multiple lower electrode modules, and the outermost ends are connected by two wires located on the same side. The outermost ends of the upper electrode modules and the outermost ends of the lower electrode modules are 180 degrees apart with the spiral center as the center of the circle. The same supply electrode is used between multiple upper electrode modules, and the same supply electrode is used between multiple lower electrode modules, and they do not affect each other, so power supply is convenient.

[0020] Compared with the prior art: under the joint action of the lower layer of the upper electrode module of an electrode unit and the upper layer of the lower electrode module, the medium in the upper row flows to both sides, and the medium in the lower row gathers in the middle, forming a spirally decreasing hurricane-shaped vortex, while the lower layer of the lower electrode module acts on the upper layer of the upper electrode module of another electrode unit to form a spirally enlarging hurricane-shaped vortex. Every time a hurricane vortex is generated, it will be accelerated once, forming a layer-by-layer acceleration effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A hurricane-shaped electrohydrodynamic pump comprises an upper electrode module 3 and a lower electrode module 4, wherein the upper electrode module 3 comprises a double layer of positive electrode 1 and negative electrode 2, wherein the positive electrode 1 and negative electrode 2 of each layer are on the same plane and are separated by a distance of an isolation zone, and the positive electrode 1 and negative electrode 2 are in a spiral shape, wherein the positive electrode 1 of the upper electrode module 3 is on the inner side, and the negative electrode 2 of the upper electrode module 3 is on the outer side, wherein the lower electrode module 4 also comprises a double layer of positive electrode 1 and negative electrode 2, wherein the positive electrode 1 and negative electrode 2 of each layer are on the same plane and are separated by a distance of an isolation zone, and the positive electrode 1 and negative electrode 2 are in a spiral shape, wherein the spiral center of the upper electrode module 3 and the spiral center of the lower electrode module 4 are on the same vertical line, and the positive electrode 1 of the lower electrode module 4 is on the inner side. On the outside, the negative electrode 2 of the lower electrode module 4 is on the inside, and an upper electrode module 3 and a lower electrode module 4 are matched to form an electrode unit. The hurricane-shaped electrohydrodynamic pump is composed of multiple electrode units arranged from top to bottom in a manner that the upper electrode module 3 faces upward. The double-layer positive electrode 1 and negative electrode 2 are separated by an isolation zone. An electrode module substrate 5 is also provided below the upper electrode module 3 and the lower electrode module 4. A liquid outlet A51 is provided on the outer circle of the electrode module substrate 5 of the upper electrode module 3, and a liquid outlet B52 is provided in the center of the electrode module substrate 5 of the lower row. The width ratio of the positive electrode 1 to the negative electrode 2 is 3:1, and the width ratio of the isolation zone to the negative electrode 2 is 1:1. A circle of protruding edges 31 are integrally formed on the electrode module substrate 5. The electrode module substrate The upper and lower surfaces of 5 are respectively provided with a large spiral groove and a small spiral groove, and the upper and lower surfaces are respectively used to place a single-layer positive electrode 1 and a negative electrode 2. The large spiral groove of the upper electrode module 3 is used to place the positive electrode 1, and the small spiral groove is used to place the negative electrode 2. The large spiral groove of the lower electrode module 4 is used to place the negative electrode 2, and the small spiral groove is used to place the positive electrode 1. The depth of the large spiral groove and the small spiral groove accounts for one-fifth of the thickness of the electrode module substrate 5. The outer circle of the electrode module substrate 5 of the upper electrode module 3 is provided with a liquid outlet A51. The same supply electrode is used between multiple upper electrode modules 3, and the outermost ends are connected by two wires located on the same side. The same supply electrode is used between multiple lower electrode modules 4, and the outermost ends are connected by two wires located on the same side. The outermost end of the upper electrode module 3 and the outermost end of the lower electrode module 4 are 180 degrees apart with the spiral center as the center of the circle.

[0032] During use, the positive electrode 1 of the lower layer of the upper electrode module 3 of an electrode unit is on the outside, and the negative electrode 2 is on the inside, and the positive electrode 1 and the negative electrode 2 are spiral-shaped. The dielectric liquid subjected to the high-voltage electric field will form positive and negative charged ions, which are attracted by the corresponding electrodes and attached to the corresponding electrodes, thereby generating a flow direction. The width of the high-voltage positive electrode is larger than that of the negative electrode, so there are more charged ions attached to the high-voltage electrode, which first causes the medium to generate a current body force that increases radially outward in steps. From a cross-sectional view, multiple electrode rings are formed on the circular cross-section, which exert a relatively large force on all media, including the part close to the edge. Since the electrode module substrate is a relatively closed small space and the medium is a fluid, the increasing radial force is converted into a relatively large axial pressure. Since the outer ring of the electrode module substrate 5 of the upper electrode module 3 is provided with a liquid outlet A51, the medium can only flow downward from the liquid outlet A51 on the outer ring of the electrode module substrate 5.

[0033] The positive electrode 1 of the upper layer of the lower electrode module 4 of this electrode unit is on the inner side, and the negative electrode 2 is on the outer side, and the positive electrode 1 and the negative electrode 2 are spiral-shaped. The dielectric liquid subjected to the high-voltage electric field will form positive and negative charged ions, and the positive and negative ions are attracted by the corresponding electrodes and attached to the corresponding electrodes, thereby generating a flow direction. The width of the high-voltage positive electrode is larger than that of the negative electrode, so there are more charged ions attached to the high-voltage electrode, which first causes the medium to generate a radially stepped current force. From a cross-sectional view, multiple electrode rings are formed on the circular cross-section, which exert a relatively large force on all media, including the part close to the center. Since a liquid outlet B52 is provided at the center of the electrode module substrate 5 of the lower electrode module 4, when the upper electrode module 3 and the lower electrode module 4 generate radial attraction between each other, imitating the generation of a natural hurricane, the liquid can only flow downward from the liquid outlet B52.

[0034] In nature, the formation of hurricanes is a highly efficient way of cooling. The rise in sea temperature creates a large temperature difference with the clouds. The wind speed also increases due to this temperature difference. Conversely, if the temperature drops, the wind speed will decrease.

[0035] Conditions for the formation of hurricanes: high water surface temperature and low cloud temperature. The temperature difference causes the wind speed to increase, achieving the effect of liquefaction and cooling.

[0036] After the lower layer of the upper electrode module 3 and the upper layer of the lower electrode module 4 are started together, it imitates the generation of hurricanes in nature, just like a breeze is needed in the early stage of a hurricane to form a vortex. The medium passing through the upper electrode module 3 flows outward step by step, and the medium passing through the lower electrode module 4 flows inward step by step, and there is a radial attraction relationship between the two. Therefore, the gas in the medium will move upward, and the liquid will condense downward, generating a spirally shrinking hurricane vortex. After the liquid condenses, the temperature will rise to form a temperature difference. The temperature difference will increase the flow rate of the vortex. The greater the temperature difference, the higher the flow rate, and the cooled refrigerant will move downward. Due to the existence of the electrode module substrate 5 of the lower electrode module 4, the liquid can only flow out from the liquid outlet A51 of the electrode module substrate 5 of the lower electrode module 4.

[0037] Then the medium flowing out of the liquid outlet A51 continues to reach the lower layer of the lower electrode module 4, flows through the lower layer of the lower electrode module 4, and enters the next electrode unit. At this time, the matching parts are the lower layer of the lower electrode module 4 of the previous electrode unit and the upper layer of the upper electrode module 3 of the next electrode unit. At this time, since the positive electrode 1 of the lower layer of the lower electrode module 4 of the previous electrode unit is on the inner side and the negative electrode 2 is on the outer side, and the positive electrode 1 and the negative electrode 2 are spiral-shaped, the dielectric liquid subjected to the high-voltage electric field will form positively and negatively charged ions, and the positive and negative ions are attracted by the corresponding electrodes, causing the medium to generate a radially inward step-increasing current force.

[0038] In the upper layer of the upper electrode module 3 of the next electrode unit, the positive electrode 1 is on the outside and the negative electrode 2 is on the inside, and the positive electrode 1 and the negative electrode 2 are spiral-shaped. The dielectric liquid subjected to the high-voltage electric field will form positive and negative charged ions, causing the medium to generate a current force that increases radially outward in steps. Therefore, when these two act at the same time, a spiral enlarging hurricane vortex will be generated, and the medium will enter from the middle liquid outlet B of the lower layer of the lower electrode module 4 of the previous electrode unit, and finally flow out from the liquid outlet A on the outer circle of the upper layer of the upper electrode module 3 of the next electrode unit, and continue to enter the lower layer of the upper electrode module 3 of the next electrode unit.

[0039] At this time, under the action of the secondary hurricane spiral acceleration, the function of layer-by-layer acceleration can be achieved, and then the above steps are repeated continuously to accelerate.

[0040] Since the formation of each hurricane is coordinated by a layer of a separate electrode unit and a layer of the next electrode unit, the attraction is greatly enhanced than that of a single layer.

[0041] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
