The first water pumping wheel 100 and the second water pumping wheel 800 are illustrated as being symmetrically disposed. The structure of the water-pumping wheel may be many, but the functions and purposes of the water-pumping wheel are the same, and for brevity description of the structure of the first water-pumping wheel 100 and the second water-pumping wheel 800, the water-pumping wheel in the following embodiments includes the first water-pumping wheel 100 and the second water-pumping wheel 800, the base 110 includes the first base 110 and the second base 110, the water-pumping blades include the first water-pumping blade 120 and the second water-pumping blade 820, and the water-pumping gap includes the first water-pumping gap 130 and the second water-pumping gap 830.
The first water break ramp 150 is formed in a variety of ways, such as by a water break blade, or by a water break disc. Taking the example of the water-beating blade formation, the first water-beating wheel 100 may include a base 110 and a plurality of first water-beating blades 120 arranged along the circumference of the base 110; the first water jet 100 may also include a first reinforcing plate 180 and a plurality of first water jet blades 120 disposed on the reinforcing plate face. Specifically, the first water-spraying wheel 100 includes a first base 110 and a plurality of first water-spraying blades 120 arranged along the periphery of the first base 110, the first water-spraying blades 120 have first sub-water-spraying inclined planes 151, and the plurality of first sub-water-spraying inclined planes 151 form the first water-spraying inclined plane 150; the second water-spraying wheel 800 includes a second base 110 and a plurality of second water-spraying blades 820 arranged along the periphery of the second base 110, the second water-spraying blades 820 have a second sub-water-spraying inclined plane, and the plurality of second sub-water-spraying inclined planes form the second water-spraying inclined plane 850.
The cross-section of the base 110 may have a variety of shapes, such as triangular, circular, oval, polygonal, etc., as exemplified by circular plate arrangements. A rotary shaft 140 is provided on the plate surface of the base 110, and a mounting hole is provided on the rotary shaft 140 along the length direction thereof, and the mounting hole is used for inserting and fixing the driving shaft of the driving motor. Of course, in other embodiments, the structure and power source for driving the rotation of the base 110 may be other more complex structures. The shape of the water blade may be many, such as square, round, fan, etc., for example, a long strip. A plurality of elongated water-fetching blades are distributed along the circumferential direction of the base 110, which is of course exemplified by uniform distribution. One end of the water blade is fixedly connected with the base 110, and the other end is a free end, and in some embodiments, the water blade may be integrally formed with the base 110. A water-beating gap is arranged between two adjacent water-beating blades, one end of the water-beating gap is blocked by the base body 110, and the other end is communicated with the outside of the water-beating wheel.
Regarding the water gap, specifically, a first water gap 130 is provided between two adjacent first water blades 120, and an end of the first water gap 130 away from the first body is communicated with the outside of the first water pump 100; a second water-pumping gap 830 is provided between two adjacent second water-pumping blades 820, and one end of the second water-pumping gap 830 away from the second body is communicated with the outside of the second water-pumping wheel 800. In this embodiment, by arranging the water-beating blades along the periphery of the base 110, a water-beating gap (a first water-beating gap 130 is formed between the first water-beating blades 120 and a second water-beating blade 820) is formed between two adjacent water-beating blades (a second water-beating gap 830 is formed between the first water-beating blades 120), when the water-beating wheel works, the water-beating blades guide water to flow out from the water-beating gap, and since the part of the water-beating gap far from the base 110 is communicated with the outside, a large amount of water flows from the water-beating gap to the heat exchanger, so that the water-beating efficiency of the water-beating wheel is improved, and the heat exchange efficiency of the heat exchanger is also improved, so that the working efficiency of the heat exchanger is improved.
The extending direction of the water striking blade may be various, for example, linear, curved or arc, and the like. When the water-spraying blades are arranged in an arc strip shape, the water-spraying gaps are gradually widened from the base 110 to the outer edge, and the water-spraying gaps are arranged in an arc shape. Through setting up the blade of beating water and being the arc for the length of the clearance of beating water is longer than the clearance of beating water that straight line blade of beating water formed under the same condition, makes the direction time of water in the clearance of beating water longer, is favorable to water to throw away according to the direction of predetermineeing.
The water-beating blades may be disposed along the radial direction of the base 110 or may be disposed at an angle with respect to the radial direction. Specifically, the extending direction of the water impeller and the radial direction of the base 110 form an included angle, and the included angle is greater than 0 ° and less than 90 °. When the water-spraying blade is disposed at an angle with the radial direction of the base 110, the water-spraying gap is also disposed at an angle with the radial direction of the base 110, and at this time, water is sprayed out along the extending direction of the water-spraying gap. The extending direction of the water beating gap can be set by setting the extending direction of the water beating blade, so that the water outlet direction of the water beating gap is effectively adjusted, water can flow onto the heat exchanger according to a preset path, the water beating efficiency of the water beating wheel is improved, and the heat exchange efficiency of the heat exchanger is improved.
When the base 110 rotates with the rotation axis 170 as an axis, the water-beating blade rotates along with the rotation of the base 110, water flows from the base 110 to the outside along the water-beating gap in the process of the rotation of the water-beating blade, when the water flows to the free end of the water-beating blade, the water flow is thrown out from the water outlet of the water-beating gap, when the water flow is thrown out, the speed and the direction of the water flow are kept in the state of the water outlet, and finally the water flows to the heat exchanger and exchanges heat with the heat exchanger.
Regarding the operation principle of the first and second water-pumping wheels 100 and 800 simultaneously operating as the first and second heat exchangers 200 and 300 for pumping water, a schematic diagram of the present invention when the water-pumping wheel pumps water is given with reference to fig. 3. When the water-pumping wheel rotates, the speed of the O point of the gear outer inclined plane (the first water pumping inclined plane 150) of the first water pumping wheel 100 in the water pumping wheel set is V, the speed direction is perpendicular to the rotation axis 140, and the speed is in direct proportion to the rotation speed of the water pumping wheel and the distance from the point to the rotation axis 140. Because the O point is positioned on the inclined plane, the air quantity of the O point along the normal direction and tangential speed of the inclined plane is V 1 And V 2 Wherein V is 1 ＝V×cos(a),V 2 =v×sin (a). Velocity component V 1 Tending to move the fluid particle at point O to the left and forward direction, while the velocity component V 2 Tending to move the fluid particles at point O to the front right. Fig. 4 and 5 show the velocity component V 1 And V 2 A component parallel to the rotation axis 140 and perpendicular to the rotation axis 140. Velocity component V 1 Can be decomposed into a velocity component V parallel to the axis of rotation 140 11 And a velocity component V parallel to the axis of rotation 140 12 Wherein V is 11 Forcing fluid particles O to the left (first heat exchanger 200 direction), V 12 Forcing fluid particle O straight ahead. Velocity component V 2 Can be decomposed into a velocity component V parallel to the axis of rotation 140 21 And a velocity component V parallel to the axis of rotation 140 22 Wherein V is 21 Forcing fluid particles O to the right (second heat exchanger 300 direction), V 22 Forcing fluid particle O straight ahead. That is to say fluid particle O is at V 12 And V 22 Is moved forward by the velocity component of V 11 And V 21 Is moved to the left and right by the velocity component of (c). Due to the velocity component V 21 In the direction of (2) the water-beating wheel is blocked, the fluid particle O can only be at V 11 The velocity component moves to the left. That is, the fluid particles O will move forward to the left under the influence of the water-filling wheel, and the left heat exchanger (the first heat exchanger 200) is cooled. Similarly, the fluid particles near the right side of the end of the water-beating wheel will move to the right and forward under the action of the water-beating wheel, for the right heat exchanger (the firstTwo heat exchangers 300) to effect cooling.
