Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to a circulating cooling device for a generator. Background Technology

[0002] A permanent magnet generator mainly consists of a stator, rotor, and end covers. The rotor is equipped with permanent magnets. When the rotor rotates under the drive of a prime mover (such as an internal combustion engine or a water turbine), the conductors in the stator windings cut the magnetic field generated by the permanent magnets, thus inducing an electromotive force in the stator windings. According to the principle of electromagnetic induction, when a part of a conductor in a closed circuit moves in a magnetic field, cutting magnetic field lines, a current is generated in the conductor.

[0003] In existing technologies, common permanent magnet generator cooling devices often require an additional independent power unit to drive the coolant circulation or other heat dissipation components, which has significant drawbacks. The independent power unit itself consumes electrical energy or other energy sources to maintain operation. For example, when using an independent motor to drive a fan or pump, the motor continuously consumes electricity during operation. This does not meet energy-saving requirements and increases the energy consumption cost of the entire power generation system. To improve upon this, a circulating cooling device for generators is proposed. Utility Model Content

A piston plate is installed in the movable chamber and is connected to the reciprocating screw through a connecting mechanism. A circulation pipe communicating with the movable chamber is wound on the casing of the generator body.

[0007] Preferably, the transmission mechanism includes two transmission pulleys mounted on the output shaft of the generator body and on the outer wall of the base and connected to the reciprocating lead screw, and the two transmission pulleys are connected by a connecting belt.

[0011] Preferably, one end of the circulating pipe is internally provided with a first valve, and the other end of the circulating pipe is internally provided with a second valve, and the first valve and the second valve are both one-way valves.

DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments.

[0023] Reference Figures 1-4

[0024] A circulating cooling device of a generator mainly comprises a generator body 1, a base 4 and a series of heat dissipation and cooling components related thereto. The generator body 1 is a core component for power generation, and a large amount of heat is generated during the operation of the generator body 1. In order to effectively dissipate heat, a plurality of upper heat dissipation fins 2 are installed on the generator body 1, which can increase the contact area with air, so as to dissipate part of the heat generated by the generator body 1 to the surrounding environment.

[0025] The base 4 serves as a support structure, which not only bears the generator body 1, but also integrates important cooling functions. A plurality of lower heat dissipation fins 7 are installed on the base 4, which further enhances the overall heat dissipation capacity.

[0026] Meanwhile, the base 4 is internally provided with a rotating chamber 8 and a movable chamber 9, and the movable chamber 9 stores cooling liquid for cooling, which is one of the key parts of the entire cooling device.

[0027] The transmission mechanism plays an important role in power transmission in the cooling device. It comprises a transmission pulley 5 installed on the output shaft of the generator body 1 and a transmission pulley 5 installed on the outer wall of the base 4 and connected with the reciprocating screw 12, and the two transmission pulleys 5 are connected by a connecting belt 6. When the generator body 1 operates, the output shaft rotates, driving the transmission pulley 5 on the output shaft to rotate. Through the transmission of the connecting belt 6, power is transmitted to the transmission pulley 5 on the outer wall of the base 4, and then the reciprocating screw 12 connected with the transmission pulley 5 rotates in the rotating chamber 8. This transmission mode utilizes the operating power of the generator body 1 itself, without the need for an additional power source, and has the advantages of energy saving and compact structure.

[0028] The connection mechanism is an important component for circulating flow of the cooling liquid. It comprises a connection frame 11 screwed on the reciprocating screw 12, and the end of the connection frame 11 is fixedly connected with a piston plate 10. When the reciprocating screw 12 rotates under the drive of the transmission mechanism, the connection frame 11 will make linear reciprocating motion along the reciprocating screw 12 due to the screw connection.

[0029] Meanwhile, in order to ensure the stability of the movement of the connection frame 11, a cross bar 13 is arranged in the rotating chamber 8, which is parallel to the reciprocating screw 12 and slidably penetrates the connection frame 11. In this way, the connection frame 11 can only make reciprocating motion along the axis direction of the reciprocating screw 12 under the limitation of the cross bar 13, thereby driving the piston plate 10 to make reciprocating motion in the movable chamber 9.

[0030] The shell of the generator body 1 is wound with a circulating pipe 3 in communication with the movable chamber 9, and the circulating pipe 3 is designed in a spiral shape. The spiral design has the following advantages: firstly, it can be tightly wound on the shell of the generator body 1, increasing the contact area with the generator body 1 and improving the heat exchange efficiency; secondly, the spiral structure allows the cooling liquid to have a certain buffering and residence time when flowing in the pipe, so that the cooling liquid can more fully absorb the heat emitted by the generator body 1.

[0031] The upper radiating fins 2 are each provided with a perforation corresponding to the circulating pipe 3, so that the circulating pipe 3 can be better combined with the upper radiating fins 2, further enhancing the heat dissipation effect.

[0032] The first valve is arranged in the interior of one end of the circulating pipe 3, and the second valve is arranged in the interior of the other end of the circulating pipe 3, and the first valve and the second valve are both one-way valves. The arrangement of the one-way valves ensures that the cooling liquid can only flow in the circulating pipe 3 in a specified direction, preventing backflow of the cooling liquid and ensuring normal operation of the cooling system.

[0033] When the piston plate 10 reciprocates in the movable chamber 9, the cooling liquid is pushed to circulate in the circulating pipe 3. After absorbing the heat of the generator body 1, the cooling liquid returns to the movable chamber 9 for cooling, and the circulation and reciprocation are repeated, so that the generator body 1 is continuously cooled.

[0034] In summary, the cooling device of the permanent magnet generator realizes circulation and efficient heat dissipation of the cooling liquid by means of ingenious structural design and use of the operating power of the generator body 1, so that the stability and reliability of the generator during operation can be effectively ensured, and the service life of the generator is prolonged.

[0035] When the generator body 1 (permanent magnet generator) is in operation, heat is generated. The output shaft of the generator body 1 rotates, and through cooperation of the transmission pulley 5 and the connecting belt 6, the reciprocating screw rod 12 can be rotated, the connecting frame 11 threaded on the reciprocating screw rod 12 can make reciprocating linear motion (the cross rod 13 serves as a guide and stabilizer), and the piston plate 10 can be driven to reciprocate in the movable chamber 9. The piston plate 10 can push the cooling liquid to circulate in the circulating pipe 3. The circulating pipe 3 is spirally wound on the shell of the generator body 1 and is provided with one-way valves at both ends. When the piston plate 10 moves, the cooling liquid flows in the circulating pipe 3 in one direction, and after absorbing the heat of the generator body 1, returns to the movable chamber 9, so that cooling is realized through circulation.

[0036] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
