Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of generators, in particular to a magnetic pole winding reinforced heat dissipation structure, a rotor and a hydro-generator. BACKGROUND

[0002] The rotor of a high-speed hydro-generator has a capacity per pole much higher than that of a conventional generator set, and the heat load per unit volume of the rotor is also larger than the corresponding value of the conventional generator set, so the problem of heat dissipation of the rotor winding is increasingly prominent. If the rotor cooling is not paid enough attention, many problems such as mechanical and insulation problems caused by excessive temperature rise of the rotor will be highlighted. Therefore, researching more efficient rotor cooling technology is conducive to solving the heat dissipation demand of the rotor of a large-capacity and high-speed hydro-generator.

[0003] The current mainstream rotor magnetic pole winding cooling methods include self-circulation symmetric radial air path cooling, forced air cooling and air internal cooling.

[0004] Among them, the self-circulation symmetric radial air path cooling provides a pressure head by the rotor, however, the rotor of a high-speed hydro-generator is a slender structure due to the material and structural strength, which is difficult to provide sufficient pressure head for the air path of the generator, and thus it is difficult to meet the heat dissipation demand of the magnetic pole winding.

[0005] Among them, the forced air cooling increases the circulating air volume of the system by setting a fan, which can improve the heat dissipation capacity of the generator, but the introduction of the fan reduces the reliability of the entire system and increases the system maintenance complexity. Moreover, the hydro-generator using forced air cooling generates a large noise during operation, which affects the physical and mental health of the on-site personnel.

[0006] Among them, the air internal cooling increases the heat dissipation area by internally setting a flow channel, which can improve the heat dissipation effect to a certain extent, and is more efficient than the traditional single-sided cooling method of the magnetic pole winding, but this cooling method also increases the difficulty of the structural design of the magnetic pole winding, resulting in an increase in maintenance cost. In addition, the air gap flow under the air internal cooling is more complex, which makes it difficult to ensure the uniform temperature rise of the magnetic pole winding.

[0007] In summary, the above cooling methods are difficult to meet the heat dissipation demand of the rotor of a high-speed hydro-generator. SUMMARY

[0008] Therefore, the technical problem to be solved by the present application is to overcome the defect that the rotor magnetic pole winding cooling method in the prior art cannot meet the heat dissipation demand of the rotor of a high-speed hydro-generator, so as to provide a magnetic pole winding reinforced heat dissipation structure, a rotor and a hydro-generator.

[0018] Optionally, the magnetic yoke has a plurality of air flow channels which are arranged towards the condensation section of the heat pipe, and the air flow channels are arranged at intervals along the rotating shaft direction of the rotor.

[0048] Example 1

[0049] The magnetic pole winding heat dissipation strengthening structure provided in this embodiment can be arranged on the magnetic pole winding 11, and is used to strengthen the heat dissipation of the magnetic pole winding 11.

[0050] As Figure 1As shown in the figure, the heat pipe 1 has an evaporation section 2 and a condensation section 3 which are in communication with each other, the evaporation section 2 is adapted to be arranged at the heat generating area of the pole winding 11, and the condensation section 3 is connected at one end of the evaporation section 2 which is close to the rotation center of the rotor. In the working process of the pole winding heat dissipation reinforcing structure provided by the embodiment, the heat pipe 1 absorbs the heat of the pole winding 11 through the evaporation section 2, and releases the heat through the condensation section 3, so that the heat dissipation of the pole winding 11 is reinforced by the refrigerant in the heat pipe 1; wherein, due to the fact that the condensation section 3 is connected at one end of the evaporation section 2 which is close to the rotation center of the rotor, under the action of the centrifugal force of the rotor, the liquid refrigerant can flow from the condensation section 3 to the evaporation section 2, and the gaseous refrigerant in the evaporation section 2 is extruded to the condensation section 3, so that the self-circulation of the refrigerant in the heat pipe 1 is realized.

[0051] As shown in the figure, Figure 1 the heat pipe 1 has an evaporation section 2 and a condensation section 3 which are in communication with each other, the evaporation section 2 is adapted to be arranged at the heat generating area of the pole winding 11, and the condensation section 3 is connected at one end of the evaporation section 2 which is close to the rotation center of the rotor. In the working process of the pole winding heat dissipation reinforcing structure provided by the embodiment, the heat pipe 1 absorbs the heat of the pole winding 11 through the evaporation section 2, and releases the heat through the condensation section 3, so that the heat dissipation of the pole winding 11 is reinforced by the refrigerant in the heat pipe 1; wherein, due to the fact that the condensation section 3 is connected at one end of the evaporation section 2 which is close to the rotation center of the rotor, under the action of the centrifugal force of the rotor, the liquid refrigerant can flow from the condensation section 3 to the evaporation section 2, and the gaseous refrigerant in the evaporation section 2 is extruded to the condensation section 3, so that the self-circulation of the refrigerant in the heat pipe 1 is realized.

[0052] As shown in the figure, Figure 1 in the embodiment, the evaporation section 2 has a heat absorption plate which is arranged vertically, and the two sides of the heat absorption plate can be respectively attached to the pole 10 and the pole winding 11, so as to improve the heat absorption efficiency. Of course, the above description is not restrictive, and in some alternative embodiments, the heat absorption plate can also have other structures, such as a plurality of parallel circular tubes, etc.

[0053] As shown in the figure, Figure 1 in the embodiment, the heat absorption plate has a plurality of horizontal through holes 4 which are arranged at intervals. Through the arrangement of the horizontal through holes 4, the fins of the pole winding 11 can be inserted, so as to increase the contact area between the heat absorption plate and the pole winding 11, and improve the heat dissipation efficiency of the pole winding 11. Of course, the above description is not restrictive, and in some alternative embodiments, the horizontal through holes 4 can be omitted.

[0054] As shown in the figure, Figure 1 in the embodiment, the heat pipe has a plurality of heat pipes which are arranged in parallel along the axial direction of the rotor. Through the arrangement, the number of heat pipes can be adjusted according to the axial length of the rotor of the high-speed hydro-generator to be cooled, so as to meet the heat dissipation requirement of the pole winding. Correspondingly, the inner side of the pole winding is also arranged to be matched with the plurality of heat pipes. Of course, the above description is not restrictive, and in some alternative embodiments, only one heat pipe can be used.

[0055] like Figure 1 As shown, in this embodiment, the condensation section 3 has a plurality of horizontally arranged heat dissipation pipes 1, with gaps between adjacent heat dissipation pipes 1. The gaps between the heat dissipation pipes 1 allow for the flow of cold air, thereby improving the cooling efficiency of the heat dissipation pipes 1. Specifically, both ends of the plurality of heat dissipation pipes 1 are respectively connected to an L-shaped channel pipe 5, and the L-shaped channel pipe 5 and the heat absorption plate can be integrally formed. Of course, the above description is not limiting; in some alternative embodiments, the plurality of heat dissipation pipes 1 can also adopt an integrally formed structure.

[0056] like Figure 2 As shown, in this embodiment, the heat pipe 1 may have two symmetrically arranged sets. These two symmetrically arranged sets of heat pipe 1 can be used to enhance heat dissipation for two adjacent magnetic pole windings 11. Of course, the above description is not limiting; the two sets of heat pipe 1 can be separately arranged or integrally formed.

[0057] like Figure 3 As shown, this embodiment may further include a wind deflector 6, which is disposed between two symmetrically arranged heat pipes 1. The wind deflector 6 has a plate structure 7 disposed on the leeward side of the condensation section 3 of the heat pipe 1. By providing the wind deflector 6, the cooling air blowing towards the condensation section 3 of the heat pipe 1 can be blocked on the leeward side, thereby preventing the cooling air from directly and rapidly blowing over the condensation section 3 of the heat pipe 1, which would lead to uneven heat dissipation from the condenser. The wind deflector 6 also increases the uniformity of the contact area between the condensation section 3 of the heat pipe 1 and the cold air, allowing the refrigerant in the condensation section 3 to dissipate heat and condense more evenly, thereby improving heat exchange efficiency.

[0058] like Figures 3-6 As shown, in this embodiment, the plate structures 7 have openings 8 between them for exposing the condenser section 3 of the heat pipe 1. During operation, cooling air blows upwards from the bottom, i.e., from the windward side of the condenser section 3 of the heat pipe 1, towards the heat pipe 1. The cooling air passes through the gaps between several heat dissipation pipes 1 in the condenser section 3, and is then blocked by the plate structures 7 of the baffle 6. The cooling air is then diverted laterally towards the heat pipe 1 that does not have an outlet directly facing it, and then discharged through the openings 8 between the plate structures 7. Of course, the above description is not limiting; in some alternative embodiments, the baffle 6 may be omitted, or other structures other than plate structures 7 may be used.

[0059] Example 2

[0060] like Figure 7 , Figures 8As shown, this embodiment provides a specific implementation of a rotor, including: a rotor yoke 9, magnetic poles 10, and magnetic pole windings 11 wound on the magnetic poles 10; the magnetic pole winding heat dissipation enhancement structure described in Embodiment 1 is disposed between two adjacent magnetic pole windings 11. During operation, the heat pipes 1 in the magnetic pole winding heat dissipation enhancement structure enhance the heat dissipation of the magnetic pole windings 11, and the refrigerant within the heat pipes 1 achieves self-circulation during the rotation of the rotor. Specifically, when the refrigerant dissipates heat and becomes liquid in the condensation section 3 of the heat pipe 1, it moves from the condensation section 3 towards the evaporation section 2 under the centrifugal force of the rotating rotor. The gaseous refrigerant located in the evaporation section 2 moves from the evaporation section 2 towards the condensation section 3 under compression, thereby completing the refrigerant self-circulation.

[0061] like Figures 9-12 As shown, in this embodiment, the magnetic pole winding 11 has heat dissipation fins 12 extending towards both sides, and part of the heat dissipation fins 12 extend into the horizontal through-holes 4 of the heat absorption plate of the evaporation section 2 of the heat pipe 1. Specifically, the heat dissipation fins 12 located on the inner side of the magnetic pole winding 11 extend into the horizontal through-holes 4 of the heat absorption plate of the evaporation section 2 of the heat pipe 1 during installation, thereby increasing the contact area between the heat pipe 1 and the magnetic pole winding 11 and improving the heat absorption rate of the evaporation section 2 of the heat pipe 1 on the magnetic pole winding 11. Of course, the above description is not limiting. In some alternative embodiments, the heat dissipation fins 12 on the magnetic pole winding 11 can be omitted, or the heat dissipation fins 12 can be provided only on the inner side of the magnetic pole winding 11.

[0062] like Figures 13-16 As shown, the magnetic yoke has several airflow channels 13 facing the condensation section 3 of the heat pipe 1, and these airflow channels 13 are spaced apart along the rotor's rotation axis. During operation, cooling air flows from the rotor's rotation center towards the condensation section 3 of the heat pipe 1 through the airflow channels 13. Because a baffle 6 is provided on the leeward side of the condensation section 3 facing the airflow channels 13, the cooling air is not blown out directly, but is blocked by the baffle 6 and diffuses towards other parts of the condensation section 3 that are not facing the airflow channels 13, and then exits from the openings 8 between the plate structures 7 of the baffle 6, thereby ensuring that the condensation section 3 of the heat pipe 1 can be cooled uniformly and improving heat dissipation efficiency.

[0063] In addition, this embodiment also provides a hydro-generator, including: a stator and a rotor disposed in the stator, wherein the rotor is provided with a magnetic pole winding enhanced heat dissipation structure as described in Embodiment 1.

[0064] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.
