The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit the application. The term "and / or" used in the specification of this application includes one or more of any and all combinations of the associated listed items.

[0030] 1, 2 and 6, the present application provides a dispenser 200 including a body 300 and an impeller 100, the impeller 100 being located within the body 300 and fixedly connected to the body 300. The impeller 100 serves to thoroughly mix the gas-liquid two-phase refrigerant and supply it to each branch line of the evaporator in equal amounts to achieve an optimal cooling effect.

[0031] 3 and 7, the impeller 100 includes a plate body 11, a diverter cone 21 (in this embodiment, the diverter member is the diverter cone 21), and a plurality of blades 12. The diverter cone 21 and the plate body 11 are arranged concentrically or nearly concentrically, and the concentricity here is not limited to concentricity in an absolute sense but also includes allowing a concentric arrangement within a tolerance range, and the plurality of blades 12 are distributed in order along the circumferential direction of the diverter cone 21, and the blades 12 are located between the diverter cone 21 and the plate body 11 and are connected to the diverter cone 21 and the plate body 11, respectively.

[0032] Furthermore, the outer wall of the plate 11 of the impeller 100 is engaged with and fixedly connected to the inner wall of the body 300 to fix the impeller 100 within the body 300, thereby improving the stability of the entire structure of the dispenser 200.

[0033] When the gas-liquid two-phase refrigerant enters the dispenser 200, it flows through the flow dividing member 20 and is guided and divided by the flow dividing member 20, so that the flow rate and state of the refrigerant flowing between the plurality of vanes 12 are essentially uniform. Furthermore, the guiding action of the plurality of vanes 12 causes the refrigerant to form a vortex, which thoroughly mixes the gas-liquid two-phase refrigerant, thereby ensuring that the gas-liquid mixture of the refrigerant distributed to each branch line is more uniform. In addition, the impeller 100 provided in this application can well guide the flow direction of the refrigerant, reduce the probability of sudden changes and reflection of the refrigerant, reduce flow resistance and pressure loss, and effectively improve the energy efficiency of the cooling system.

[0034] 2 and 3, the diverting cone 21, the vanes 12 and the plate 11 are arranged in this order along the axial direction of the plate 11, with one end of the vanes 12 connected to the bottom surface of the diverting cone 21 and the other end of the vanes 12 connected to the end surface of the plate 11 close to the diverting cone 21. The refrigerant diverted by the diverting cone 21 can directly flow to the vanes 12 and is further guided by the vanes 12 to form a vortex flow and thoroughly mix the gas-liquid two-phase refrigerant, thereby ensuring that the gas-liquid mixture of the refrigerant distributed to each branch line of the evaporator is more uniform.

[0035] 3, 4 and 5, the blades 12 are distributed in a radial spiral pattern along the direction from the center of the plate body 11 to the edge. By arranging the blades 12 in a radial spiral pattern, it becomes easier for vortexes to be generated in the refrigerant flowing into the impeller 100. Furthermore, by increasing the degree of turbulence of the refrigerant, the gas-liquid mixing and flow distribution of the refrigerant can be made more uniform, thereby improving the mixing effect of the refrigerant.

[0036] In this embodiment, the spiral direction of the plurality of blades 12 is clockwise. In other embodiments, the spiral direction of the plurality of blades 12 may be counterclockwise.

[0037] 2, 3 and 5, the multiple blades 12 are connected to each other along the radial direction of the plate body 11 on the side closest to the central axis of the plate body 11. In this way, the connection area between the blades 12 is increased, thereby improving the overall strength of the blades 12, and the connection area between the blades 12 and the bottom surface of the diverter cone 21 is also increased, thereby improving the connection strength between the blades 12 and the diverter cone 21, and improving the overall structural strength of the impeller 100.

[0038] The blades 12 all have the same shape, size, and helix angle. In this way, the gas-liquid mixture and flow rate distribution of the refrigerant flowing between two adjacent blades 12 can be made more uniform, thereby further improving the performance of the cooling system.

[0039] Furthermore, the axial height of each blade 12 gradually decreases along the direction from the center to the edge of the plate body 11. In this way, when the refrigerant collides with the impeller 100, the blades 12 near the center of the plate body 11 receive a relatively large force, and the blades 12 are connected to each other at their relatively higher sides, which further improves the structural strength of the entire impeller 100 and allows the blades 12 to better cope with the collision of the refrigerant. The height of the blades 12 is relatively small at the edge of the plate body 11, making it easy to connect them to the plate body 11.

[0040] 3, the flow diverter cone 21 is a cone. In one embodiment, the flow diverter cone 21 is cone-shaped. In this way, it can more easily play the role of guiding flow diverter. In another embodiment, the flow diverter cone 21 can be a pyramid as long as it can achieve the same flow diverter effect.

[0041] 6, 7 and 8, at least a part of the blade 12 and at least a part of the diverting cone 21 are located in the plate body 11. The plate body 11, the blade 12 and the diverting cone 21 are arranged in order along the radial direction of the plate body 11, and the blade 12 is connected to the circumferential side of the diverting cone 21 and the inner wall of the plate body 11, respectively. In this way, the refrigerant diverted by the diverting cone 21 can directly flow to the blade 12, and is further guided by the multiple blades 12, so that the refrigerant forms a vortex and thoroughly mixes the gas-liquid two-phase refrigerant, thereby ensuring that the gas-liquid mixture of the refrigerant distributed to each branch line of the evaporator is more uniform. In addition, the blade 12 has a relatively large connection area with the circumferential side of the diverting cone 21 and the inner wall of the plate body 11, which improves the connection strength between the blade 12, the diverting cone 21 and the plate body 11, and improves the overall strength of the impeller 100.

[0042] Furthermore, the vanes 12 are spaced apart, and are all inclined, with the same inclination angle and direction. The inclined vanes 12 play a role in guiding and damping the flow of the refrigerant, and the refrigerant forms a high-speed and uniform vortex on the surface of the vanes 12, so that the refrigerant can be mixed more uniformly, and the gas-liquid mixing and flow distribution of the refrigerant to each branch line are more uniform, which effectively avoids the occurrence of drift phenomenon, improves the heat exchange effect of the entire cooling system, and effectively improves the energy efficiency of the cooling system.

[0043] 6, the included angle between each vane 12 and the central axis of the diverting cone 21 is A, and is 30°≦A≦60°. This can ensure the liquid separation effect, make the gas-liquid mixture and flow distribution of the refrigerant flowing through each vane 12 more uniform, and minimize the pressure drop to further improve the performance of the cooling system. In other embodiments, the included angle between the vane 12 and the central axis of the diverting cone 21 can be selected to be different depending on the actual application.

[0044] 9, 10 and 11, the blade 12 includes a connecting portion 121 and a non-connecting portion 122, and is connected and fixed to the connecting portions of the flow diverting cone 21 and the plate body 11 by the connecting portion 121, respectively, and the outer edge contour of the non-connecting portion 122 of the blade 12 is provided to form an arc surface. The connecting portion 121 makes it easier to connect the blade 12 to the flow diverting cone 21 and the plate body 11, and the connection becomes more stable. When set in this manner, the connecting portion 121 connects the edge of the flow diverting hole to the side edge of the blade, thereby strengthening the blade's ability to receive the impact of the gas and liquid flowing in through the flow diverting hole and stabilizing the integrally molded structure of the blade and the plate body.

[0045] 7, the flow diverting cone 21 includes a conical portion 211 and a columnar portion 212, the conical portion 211 is used to guide and diverge the refrigerant, the columnar portion 212 is used to connect the blades 12, and the conical portion 211 and the columnar portion 212 are connected to each other. Specifically, along the axial direction of the plate body 11, one end of the columnar portion 212 is connected to the bottom surface of the conical portion 211, and the conical portion 211 is provided at a position higher than the blades 12. The sides of the multiple blades 12 away from the plate body 11 are connected to the circumferential side of the columnar portion 212. The setting of the columnar portion 212 can make the connection between the flow diverting cone 21 and the blades 12 easier and improve the connection strength.

[0046] In one embodiment, the cone portion 211 is cone-shaped. In this way, it can more easily play the role of guiding the flow. In another embodiment, the cone portion 211 can be a pyramid as long as it can achieve the same flow-diverting effect.

[0047] 4 and 9 in the first and second embodiments, the projections of two adjacent blades 12 onto a plane perpendicular to the central axis of the plate body 11 overlap each other. That is, when the size of the space is constant, by providing more blades 12 and making the structure more compact, the degree of gas-liquid mixing can be further improved and the mixing effect of the refrigerant can be improved.

[0048] The impeller 100 is integrally molded. Specifically, the impeller 100 may be processed and molded using any of the processes of powder metallurgy, 3D printing, and laser sintering. In this way, the overall structural strength of the impeller 100 can be effectively improved. At the same time, the assembly time can be shortened, the processing difficulty can be reduced, the processing efficiency can be improved, and the cost can be reduced. Of course, in other embodiments, the impeller 100 may be manufactured and molded by other conventional methods known in the art, which are not limited here.

[0049] Furthermore, the integral design of the partition plate 11, the flow dividing member 20 and the blades 12 simplifies the impeller structure and makes the flow dividing member 20 stronger so that it can withstand the impact of gas and liquid.

[0050] In some embodiments, referring to Figures 12 to 15, an impeller 100 includes an impeller body 10 and a diverting member 20, the impeller body 10 includes a plate body 11 and blades 12, a plurality of blades 12 are provided on the plate body 11, and a plurality of diverting holes 111 are provided on the plate body 11, the diverting holes 111 correspond one-to-one to the blades 12, the plurality of diverting holes 111 are radially distributed around the diverting member 20 and are spaced apart along the circumferential direction of the diverting member 20, so as to evenly divert the liquid and avoid drift.

[0051] Furthermore, the flow dividing member 20 is integrally formed with the plate body 11, simplifying the structure of the impeller 100 and facilitating uniform distribution of gas and liquid to each flow dividing hole 111, and a plurality of vanes 12 are provided at intervals along the circumferential direction of the flow dividing member 20 and are used to guide the gas and liquid diverted by the flow dividing member 20 to the flow dividing holes 111, ensuring uniform distribution. Compared with the related art, when the impeller 100 provided in the present application performs gas-liquid distribution, the flow dividing member 20 receives the gas and liquid and guides them to the flow dividing holes 111, thereby avoiding uneven flow, and the vanes at the flow dividing holes 111 perform gas-liquid distribution.

[0052] 13 and 19, the impeller 100 uses a design in which the flow dividing member 20 and the impeller body 10 are molded together, and if no connecting portion is provided, the gas and liquid divided by the flow dividing member 20 can easily flow directly into the flow dividing holes 111, and the leakage flow due to the gap at the connecting portion can be avoided. The design in which the flow dividing member 20 and the plate body 11 are molded together simplifies the impeller structure, and the flow dividing member is made strong so that it can withstand the impact of the gas and liquid. Furthermore, the flow dividing member 20 and the blades 12 work together, and the gas and liquid are primarily divided by the flow dividing member 20 molded together with the impeller body 10, and the primarily divided gas and liquid are guided to the blades 12 for secondary division, and the gas and liquid are guided to each flow dividing hole 111 and flow again into the blades 12 corresponding to the flow dividing holes 111, and are uniformly divided.

[0053] When the impeller body 10 is applied to the dispenser 200, the diversion direction of the diversion member 20 in the chamber installed in the dispenser 200 corresponds to the gas-liquid inlet and outlet of the dispenser 200. However, since this is not the focus of the present application, it should be understood by those skilled in the art that the description will be omitted in the following description.

[0054] 12 and 13, the flow diverting member 20 may be a flow diverting cone 21 or a flow diverting groove 22. The flow diverting cone 21 is formed by protruding outward from the end face of the plate body 11 along the axial direction of the impeller 100, and the flow diverting groove 22 is formed by recessing inward from the end face of the plate body 11. Specifically, the flow diverting cone 21 and the plate body 11 are integrally molded, and the flow diverting cone 21 guides the gas and liquid to the flow diverting hole 111 after the primary flow diverting, so that the gas and liquid are secondarily and uniformly diverted by the blades 12. Furthermore, the flow diverting groove 22 and the plate body 11 are integrally molded, and the gas and liquid flow into the flow diverting groove 22 to be buffered, and then overflow into the flow diverting hole 111 to be uniformly diverted.

[0055] 14 and 15, the blade 12 includes a blade main body 123 and a flow dividing portion 124, and the flow dividing portion 124 is provided on the blade main body 123 so that the gas-liquid two-phase refrigerant flowing to the blade 12 through the flow dividing holes 111 is evenly divided. The flow dividing portion 124 may be a guide groove 1241 or a notch 1242, and specifically, the blade 12 is provided with a guide groove 1241 for more evenly dividing the refrigerant, and further, the blade 12 is provided with a notch 1242 for more evenly dividing the gas and liquid on the blade 12.

[0056] 12, the flow diverting member 20 is a flow diverting cone 21, the large diameter end of which is provided on the plate body 11 and molded integrally with the plate body 11, and the small diameter end of the flow diverting cone 21 is provided away from the plate body 11. Specifically, the gas and liquid flow through the small diameter end of the flow diverting cone 21 along the tapered surface to the large diameter end of the flow diverting cone 21, and during this flow process, the gas and liquid are primarily diverted, and the primarily diverted gas and liquid are guided to each of the flow diverting holes 111. With this setting, the large diameter end of the flow diverting cone 21 is provided on the plate body 11, and the small diameter end is provided away from the plate body 11, which absorbs the impact of the gas and liquid, avoids direct impact on the end face of the impeller, and guides the flow direction of the gas and liquid, making it easier for the flow rate to flow into the flow diverting holes 111. However, without being limited to this, the dimension of the large diameter end of the diversion cone 21 is designed to be larger than the distance from each diversion hole 111 to the center of the plate body 11, so that the gas and liquid primarily diverted by the diversion cone 21 is led directly to the diversion hole 111, thereby avoiding the drift phenomenon caused by flowing through the plate body 11.

[0057] In one embodiment, as shown in FIGS. 12 to 16, the angle (acute angle) between the tapered surface of the flow dividing cone 21 and the horizontal plane of the plate body 11 is B, and the range of the value of B is 30° < B < 60°. In this way, the gas-liquid is uniformly divided for the first time. However, it is not limited thereto. When different types of gas-liquid are divided, the angle B is adjusted within the range of values. For example, when the range of the value of B is 35° < B < 40°, the gas-liquid is uniformly divided and the gas-liquid divided for the first time is guided to each flow dividing hole 111. When set in this way, the value of the angle B is set between 30° and 60°, the tapered surface of the flow dividing cone is easily contacted by the gas-liquid, and the flow rate is uniformly divided.

[0058] In one embodiment, as shown in FIGS. 12 to 15, the diameter of the large-diameter end of the flow dividing cone 21 is larger than the linear distance from the end of the flow dividing hole 111 close to the flow dividing cone 21 to the center of the plate body. Therefore, after the gas-liquid is divided for the first time through the flow dividing cone 21, it directly flows into each flow dividing hole 111 and is divided for the second time.

[0059] In one embodiment, as shown in FIGS. 12 to 15, the flow dividing member 20 is a flow dividing groove 22 for buffering the gas-liquid from above. Specifically, the flow dividing groove 22 is formed by being recessed inward from the surface (end face) of the plate body 11. When the gas-liquid enters the impeller 100 and is divided, the gas-liquid enters the flow dividing groove 22, and when a certain amount is reached, an overflow occurs, and the overflowed gas-liquid is divided into each flow dividing hole 111. When set in this way, a recessed flow dividing groove 22 is formed on the end face of the plate body 11, the gas-liquid enters the flow dividing groove 22 to form a buffer, and overflows to each flow dividing hole 111.

[0060] Furthermore, the flow diversion groove 22 may be a tapered groove, a hemispherical groove, or a trapezoidal groove, and since a tapered groove, a hemispherical groove, or a trapezoidal groove does not have a cross-sectional layer that is directly subjected to the impact of the gas and liquid, it reduces cushioning and avoids deformation of the flow diversion groove 22. Specifically, when the diversion groove 22 is a tapered groove, the gas and liquid flow into the small diameter end through the tapered surface of the tapered groove until it overflows from the diversion groove 22, and the overflowing gas and liquid flows into each diversion hole 111 and is evenly diverted, and when the diversion groove 22 is a hemispherical groove, the gas and liquid flow into the hemispherical groove through the spherical surface until it overflows from the diversion groove 22, and the overflowing gas and liquid flows into each diversion hole 111 and is evenly diverted, but is not limited to this, and the diversion groove 22 may be a trapezoidal groove, and a trapezoidal groove can withstand the impact force when a large amount of gas and liquid flows into the diversion groove 22, making the diversion groove 22 less likely to deform. Similarly, when the diversion groove 22 is a tapered groove, the range of the included angle (acute angle) between the tapered surface of the diversion groove 22 and the horizontal plane of the plate body 11 is 35° to 60°, making it easy for the gas and liquid to flow smoothly into the diversion groove 22 and overflow into each diversion hole 111 to be diverted again.

[0061] In one embodiment, as shown in Figures 12 to 15, a plurality of blades 12 and a plurality of diversion holes 111 are uniformly arranged along the circumferential direction of the diversion member 20, and the plurality of blades 12 are radially arranged and correspond one-to-one to each diversion hole 111. After primary diversion by the diversion member 20, the gas and liquid are guided to each diversion hole 111, and the plurality of blades 12 which correspond one-to-one to each diversion hole 111 perform secondary uniform diversion of the gas and liquid.

[0062] Specifically, by arranging them radially and uniformly in the circumferential direction, after the primary flow division by the flow diverting member 20, it becomes easy to guide the gas and liquid directly to the blades 12 at each flow division hole 111, thereby preventing drift. However, without being limited to this, U-shaped grooves may be additionally provided at intermediate positions between the flow diverting member 20 and the plurality of blades 12 arranged uniformly in the circumferential direction, with each U-shaped groove corresponding one-to-one to the flow division hole 111, and the gas and liquid primarily diverted by the flow diverting member 20 passes through the U-shaped groove and flows directly into the flow division hole 111, and is secondarily diverted without drift.

[0063] In one embodiment, as shown in Figures 12 to 15, the blade 12 includes a blade body 123 and a diverting section 124 provided on the blade body 123, so that the gas and liquid flowing through the diverting hole 111 to the blade 12 can be diverted more uniformly. Specifically, the diverting section 124 is a guide groove 1241, which is formed along the thickness direction of the blade body 123 and recessed inward from the end face of the blade body 123. A plurality of guide grooves 1241 are provided on the blade body 123 at intervals and arranged side by side along the length direction of the blade body 123. Depending on the type of gas and liquid, a phenomenon occurs in which the gas and liquid adhere to the blade body 123. However, by providing a plurality of guide grooves 1241, it becomes easier to divert the gas and liquid uniformly. The guide groove 1241 is provided along the length direction of the blade body 123, and the gas and liquid are diverted to the outside of the blade body 123 at a constant inclination. The multiple flow guide grooves 1241 are arranged in a line at intervals along the longitudinal direction of the blade body 123, and secondarily divert the gas and liquid diverted through the diversion cone 21 or the diversion groove 22, thereby strengthening the diversion of the flow rate at the blade 12 and preventing the flow rate flowing into the blade 12 through the diversion hole 111 from being too large, resulting in uneven diversion.

[0064] In some other embodiments, the diverting portion 124 is a sawtooth notch 1242, which is provided at one end of the blade body 123 away from the plate 11 along the width direction of the blade body 123, and is used to uniformly divert the gas and liquid flowing to the blade 12 through the diverting hole 111, and is provided at one end of the diverting blade 12 away from the plate 11, making it easy for the blade 12 to divert again through the tooth-shaped notch 1242 after the blade 12 uses the inclination to divert the gas and liquid, ensuring uniform gas-liquid diversion. However, the present invention is not limited to this, and in order to divert the gas and liquid evenly, a V-shaped groove is provided on the blade body 123, and a V-shaped groove nozzle is added to one end of the V-shaped groove away from the plate 11, thereby preventing deviation when the gas and liquid are diverted at the blade 12.

[0065] The principle of flow division of the impeller 100 provided in this embodiment is as follows. The impeller 100 mainly uses the flow division member 20 and the blades 12 to perform flow division. When gas and liquid flow into the impeller 100, they are first primarily divided by the flow division member 20. If the flow division member 20 is a flow division cone 21, the gas and liquid flow through the small diameter end of the flow division cone 21, flow along the tapered surface, and reach the large diameter end of the flow division cone 21 where they are divided. The flow division cone 21 guides the divided gas and liquid to each flow division hole 111, completing the primary division. If the flow division member 20 is a flow division groove 22, the gas and liquid flow directly into the flow division groove 22 until it overflows, and the overflowing gas and liquid are then guided to each flow division hole 111. The gas and liquid are diverted to the flow diversion hole 111, completing the primary diversion, and then the gas and liquid that flowed into the flow diversion hole 111 flows to the blade 12 that corresponds one-to-one with the flow diversion hole 111. If the blade 12 is provided with a flow guide groove 1241, the gas and liquid that flowed to the blade 12 is diverted evenly via the flow guide groove 1241, completing the secondary diversion, and if the blade 12 is provided with a tooth-shaped notch 1242, the gas and liquid that flowed to the blade 12 is diverted evenly via the tooth-shaped notch 1242, completing the secondary diversion.

[0066] 17, when the impeller in the related art divides or directs the flow, the fluid first passes through the diversion hole of the impeller 100A, reaches the blade 200A, and is further guided by the blade 200A. When the impeller 100A is applied to a dispenser, it is expected that the gas and liquid coming out through the distribution port of the dispenser can be uniformly mixed. However, the blade in the related art is manufactured by a punching molding method, and after punching, the blade 200A has an inclination angle, and has a certain gap ΔL1 between the blade 200A and the side wall where the diversion hole of the impeller 100A is located. In this case, the width of the blade 200A projected onto the plane where the impeller 100A is located is smaller than the width of the diversion hole. Due to the existence of the gap ΔL1, when a part of the fluid passes through the diversion hole, it does not contact the blade, that is, the liquid in this part cannot be guided by the blade, which may cause uneven gas-liquid mixing in the dispenser.

[0067] Referring to FIG. 18, the wing 12 of the present application is inclined in a direction away from the diversion hole 111 from the plate body 11, and the width of the wing 12 projected onto the plate body 11 is equal to or greater than the width L1 of the diversion hole 111, that is, the width of the wing 12 projected onto the plate body 11 is L1+ΔL2, where ΔL2 may be zero, so that when the fluid passes through the diversion hole 111, all the fluid comes into contact with the wing 12, which is advantageous for uniform gas-liquid diversion in the dispenser 200.

[0068] 19 to 21, the present invention provides an impeller 100, which includes a plate body 11 and a blade 12, and the blade 12 and the plate body 11 are integrally formed. Furthermore, the plate body 11 is provided with a plurality of diversion holes 111, which are radially arranged on the plate body 11 to divert gas and liquid, and the plurality of blades 12 correspond one-to-one to the plurality of diversion holes 111, so that the gas and liquid flowing through the diversion holes 111 are diverted to each blade 12, thereby avoiding drift.

[0069] 13, 19 to 20, in some embodiments, the blades 12 are inclined in a direction away from the plate body 11 toward the diversion hole 111, and the width of the blades 12 projected onto the plate body 11 along the axial direction of the impeller 100 is greater than or equal to the width of the diversion hole 111, so that the gas and liquid flowing through the diversion hole 111 are completely directed to the blades 12 and divided, thereby preventing the gas and liquid from flowing directly through the gap between the blades 12 and the diversion hole 111 through the diversion hole 111 and flowing out directly from the impeller 100, which makes it difficult to divide the flow evenly.

[0070] When the impeller is used in the dispenser 200, it is installed in the chamber of the dispenser 200, and the flow-diverting direction of the flow-diverting member 20 and the flow-guiding direction of the vanes 12 correspond to the gas-liquid inlet and outlet of the dispenser 200, respectively. Since the present application is an improvement on the structure of the impeller, it should be understood by those skilled in the art that the contents of the dispenser 200 will not be described hereinafter.

[0071] 13, 19 and 20, the blades 12 and the plate 11 are integrally molded by powder metallurgy, and different materials of the impeller 100 need to be used to separate the gas and liquid according to different gas and liquid components. Powder metallurgy can process a variety of metal materials, and the blades 12 and the plate 11 are integrally molded to save material and facilitate the separation of a variety of gas and liquid. In another embodiment, the blades 12 and the plate 11 can be integrally molded by 3D printing, and the impeller 100 is easily damaged when processing a plurality of blades 12 because of the integral molding design, but 3D printing can be molded and designed based on a diversified structure, which avoids the difficulty of integral molding due to the specialization of the structure of the impeller 100. The blades 12 and the plate body 11 may be molded integrally by laser sintering. When gas and liquid enter the impeller 100 and are diverted, it is necessary to ensure that the surface of each diverting member of the impeller 100 is smooth in order to divert the gas and liquid evenly. However, the impeller 100 produced by laser sintering has good precision and high strength, and it is easy for the diverting members 20 and the blades 12 to divert the gas and liquid evenly.

[0072] In one embodiment, as shown in Figures 14 and 20, the impeller 100 includes a connection part 30 for connecting the plate body 11 and the blade 12, specifically, the connection part 30 is connected from the edge of the flow dividing hole 111 to the side edge of the blade 12 so that the blade 12 and the plate body 11 are integrally formed, and when the gas and liquid flow to the blade 12 through the flow dividing hole 111, the connection part 30 stabilizes the blade 12, and prevents the blade 12 from being deformed and even broken due to the impact of the gas and liquid on the blade 12, thereby improving the strength. However, the present invention is not limited to this, and a reinforcing rib is added to the back of the blade 12 and connected to the back of the plate body 11, and the height of the reinforcing rib is adjusted according to the inclination angle of the blade 12 to ensure that the blade 12 can withstand the impact of gas and liquid with different strengths.

[0073] Furthermore, when one side of the blade 12 is inclined, a single connecting portion 30 is provided to support the blade 12 on that side and receive the gas and liquid, and when both sides of the blade 12 are inclined, two connecting portions 30 are provided to support the blades 12 on both sides and receive the gas and liquid. By selecting the number of connecting portions 30 according to the angle of inclination of the blade 12 and the strength required to receive the flow of gas and liquid, the structure in which the blade 12 and the plate body 11 are molded integrally is stabilized.

[0074] In one embodiment, as shown in Fig. 13, Fig. 19 to Fig. 20, the blade 12 is fan-shaped, and the fan-shaped blade 12 easily separates the gas and liquid, and the gas and liquid smoothly flow into the flow guide groove 1241, making it easy to separate the gas and liquid. In another embodiment, as shown in Fig. 21, the cross section 125 of the blade 12 is triangular, and when the gas and liquid flow through the blade 12, they are tilted, making it easy to separate the gas and liquid. Furthermore, the width of the cross section 125 of the blade 12 gradually decreases from one end close to the plate body 11 to one end away from the plate body 11, and the gas and liquid flowing through the flow separation hole 111 to the blade 12 is separated along the blade 12 having the triangular cross section 125. However, the present invention is not limited to this, and the cross section 125 of the blade 12 is provided in an arc shape, making it easy to uniformly separate the gas and liquid on the blade 12.

[0075] The principle of the flow splitting of the impeller 100 provided in this embodiment is as follows: The impeller 100 mainly uses the blades 12 to perform uniform flow splitting, and the flow splitting member 20 works together to perform flow splitting. When the gas and liquid flow into the impeller 100, it first performs primary flow splitting through the flow splitting member 20. The gas and liquid after splitting flows into each splitting hole 111. Since the width of the blades 12 projected on the plate body 11 is equal to or greater than the width of the splitting hole 111, the gas and liquid flowing into the splitting hole 111 flows directly into the splitting section 124 of the blade 12. When the splitting section 124 is the guide groove 1241, the gas and liquid flowing into the blade 12 is uniformly split through the guide groove 1241, and the secondary splitting is completed. When the splitting section 124 is the tooth-shaped notch 1242, the gas and liquid flowing into the blade 12 is uniformly split through the tooth-shaped notch 1242, and the secondary splitting is completed.

[0076] 1, 2 and 6, the present application provides a dispenser 200 including an impeller 100 as described above.
