Description
Technical Field
[0001] The invention relates to the technical field of cooling devices, and in particular to a heat exchange mechanism capable of improving the working quality of a generator. Background Art
[0002] A generator is a device that can convert other forms of energy into electrical energy. The most common generator converts rotational mechanical energy into electrical energy through the principle of electromagnetic induction. It includes coils and permanent magnets inside. When the generator is used for a long time or under high load, it will gradually heat up. As the temperature rises, the resistance of the coil in the generator gradually increases, which will have a certain impact on the current and cause the working quality of the generator to decline. The most common way to dissipate heat for generators is to install fan blades on the rotor shaft of the generator. When the generator is driven to rotate, the fan blades are used to dissipate airflow. However, the coils of many high-power generators are thicker and fit against the inner wall of the casing. Dissipation of heat by airflow alone is not sufficient. Under long-term or high-load conditions, there is still a large heating problem. Summary of the invention

DETAILED DESCRIPTION

The medium cavity 2 is opened in the side wall surface of the generator housing 1. The medium cavity 2 and the heat exchange fin 3 are connected by an extraction connecting pipe 4 and a return connecting pipe 5. The medium in the medium cavity 2 flows into the heat exchange fin 3 through the extraction connecting pipe 4, and the medium in the heat exchange fin 3 returns to the inside of the medium cavity 2 through the return connecting pipe 5. Figure 6 As shown in the figure, an intermediate driving tube 6 is arranged on the suction connecting tube 4, a heat-conducting inner tube 7 is arranged in the intermediate driving tube 6, the suction connecting tube 4 is connected with the interior of the intermediate driving tube 6 through the heat-conducting inner tube 7, an annular air cavity 8 is opened between the heat-conducting inner tube 7 and the intermediate driving tube 6, and an adaptive driving structure is arranged inside and outside the intermediate driving tube 6.
[0030] like Figure 6 As shown in the figure, the adaptive driving structure includes a flow-blocking plug 601, a supporting spring 602, a limiting inner wall ring 603 and a driven magnetic ring 604. The flow-blocking plug 601 is sealed and arranged at the end position of the heat-conducting inner tube 7. A supporting spring 602 is connected between the flow-blocking plug 601 and the inner wall surface of the intermediate driving tube 6. The supporting spring 602 applies an elastic thrust to the flow-blocking plug 601 to move the heat-conducting inner tube 7. A limiting inner wall ring 603 is fixedly arranged on the inner wall surface of the intermediate driving tube 6, and a driven magnetic ring 604 is arranged on the side of the limiting inner wall ring 603 away from the flow-blocking plug 601.
[0031] A central tube 605 is fixedly provided inside the driven magnetic ring 604, a matching blocking eave 606 is fixedly provided in the central tube 605, a secondary blocking piece 607 is provided on the side of the matching blocking eave 606 away from the limiting inner wall ring 603, a tension spring bracket 609 is fixedly provided on the inner wall surface of the central tube 605, a blocking piece tension spring 608 is connected between the tension spring bracket 609 and the secondary blocking piece 607, and the blocking piece tension spring 608 applies an elastic pulling force on the secondary blocking piece 607 to move toward the matching blocking eave 606.
[0032] The outer sleeve of the intermediate driving tube 6 is equipped with an external magnetic ring 610, which is magnetically matched with the driven magnetic ring 604. When the external magnetic ring 610 moves along the axial direction of the intermediate driving tube 6, the driven magnetic ring 604 can be driven to move axially through the magnetic match between the external magnetic ring 610 and the driven magnetic ring 604. The external fixed sleeve of the external magnetic ring 610 is provided with a magnetic ring fixing seat 611, and a strip groove 612 is provided at the bottom of the magnetic ring fixing seat 611. The length direction of the strip groove 612 is perpendicular to the axial direction of the external magnetic ring 610, and a dynamic turntable 613 is provided below the magnetic ring fixing seat 611.
[0033] The dynamic rotating disk 613 is provided with a dynamic shifting groove 614, in which a moving slider 615 is provided for sliding and limiting. A toggle pin 616 is fixedly provided on the upper surface of the moving slider 615, and the toggle pin 616 is inserted in the bar groove 612 for limiting. When the dynamic rotating disk 613 rotates, the toggle pin 616 cooperates with the bar groove 612 for limiting, so as to drive the magnetic ring fixing seat 611 and the external magnetic ring 610 to reciprocate axially. A positioning blind hole 617 is provided on the surface of the moving slider 615, in which a reset spring 618 is inserted. A hydraulic cylindrical cavity 619 is provided in the dynamic rotating disk 613, and the hydraulic cylindrical cavity 619 is connected with the dynamic shifting groove 614. A hydraulic piston 620 is provided in the hydraulic cylindrical cavity 619 for sealing and sliding, and the hydraulic piston 620 is fixedly installed with the moving slider 615.
[0034] A central bottom shaft 621 is fixedly provided at the center position of the lower surface of the dynamic turntable 613, a bottom shaft support arm 622 is fixedly provided on the outside of the heat exchange fin 3, the central bottom shaft 621 is rotationally limited and installed inside the bottom shaft support arm 622, a pulley 623 is fixedly provided on the central bottom shaft 621, a regulating cavity 624 is opened in the central bottom shaft 621, a regulating piston 625 is provided in the regulating cavity 624, and the regulating piston 625 is in sealing contact with the inner wall surface of the regulating cavity 624.
[0035] The dynamic turntable 613 and the central bottom shaft 621 are provided with an alternating flow channel 626, and the hydraulic cylindrical cavity 619 is connected with the regulating cavity 624 through the alternating flow channel 626. A lifting cylinder 627 is provided below the regulating piston 625. When the lifting cylinder 627 is extended, it can push the regulating piston 625 to move upward. A cylinder fixing arm 628 is fixedly provided between the lifting cylinder 627 and the heat exchange fin 3, and the lifting cylinder 627 is connected with the annular air cavity 8; Figure 8 As shown in the figure, a circular disk is arranged below the regulating piston 625, and a bearing is arranged between the circular disk and the regulating piston 625, so that the circular disk can rotate relative to the regulating piston 625, and the telescopic shaft of the lifting cylinder 627 contacts the circular disk when extending the lifting regulating piston 625, thereby reducing the wear between the regulating piston 625 and the telescopic shaft of the lifting cylinder 627 when the regulating piston 625 rotates following the central bottom shaft 621.
[0036] The inner partition of the medium cavity 2 is fixedly provided with a partition inner edge 201, such as Figure 5 As shown in the figure, the flow direction of the cooling medium in the medium cavity 2 is limited by the dividing inner edge 201 to ensure that the cooling medium in the medium cavity 2 flows in an orderly manner. The outer surface of the heat-conducting inner tube 7 is fixedly provided with an annular fin 701, and the annular fin 701 is located inside the annular air cavity 8. The annular fin 701 increases the contact heat conduction area between the outer surface of the heat-conducting inner tube 7 and the air inside the annular air cavity 8.
[0037] When the heat exchange mechanism of the present invention is in use, the winding coil of the generator is fixedly mounted on the inner wall of the generator housing 1 and is in thermal contact with the generator housing 1. The medium cavity 2 and the heat exchange fins 3 are both filled with cooling medium and are connected through the suction connecting pipe 4 and the return connecting pipe 5. A fan device is provided on one side of the heat exchange fins 3 for cooling the heat exchange fins 3. The above-mentioned fan device is omitted in the accompanying drawings.
[0038] The pulley 623 is connected to the input shaft of the generator through a transmission belt (the transmission belt part is not shown in the figure), so that the power source equipment of the generator such as an external diesel engine can drive the pulley 623 to rotate while driving the generator.
[0039] like Figure 6 , Figure 7 and Figure 8As shown in the figure, while the pulley 623 rotates, the dynamic turntable 613 is driven to rotate through the central bottom shaft 621, and the driving pin 616 rotates at this time. The driving pin 616 cooperates with the strip groove 612 to drive the magnetic ring fixing seat 611 and the external magnetic ring 610 to perform axial reciprocating motion.
[0040] At this time, the external magnetic ring 610 drives the driven magnetic ring 604 to reciprocate axially through magnetic force. Figure 6 Taking the middle perspective as an example, when the driven magnetic ring 604 moves to the right, the secondary plug 607 is closed, the flow blocking plug 601 is opened, the intermediate driving tube 6 absorbs the medium, and at the same time squeezes the medium on the right side of the driven magnetic ring 604 into the heat exchange fin 3; when the driven magnetic ring 604 moves to the left, the secondary plug 607 is opened, and the flow blocking plug 601 is closed, so that the driven magnetic ring 604 is reset, and the medium will not flow back. Compared with traditional structures such as piston pumps or centrifugal pumps, the use of active sealing components can be completely avoided. The above-mentioned active sealing components refer to the seal at the power shaft in the centrifugal pump, or the seal between the piston and the cylinder wall in the piston pump. The active sealing components have a greater probability of leakage as they wear. The connections between the pipelines of the present invention are all static seals, which greatly reduce the probability of leakage of the cooling medium.
[0041] After the generator coil transfers heat into the cooling medium in the medium cavity 2, it first flows out through the suction connecting pipe 4. Therefore, the high-temperature cooling medium will first pass through the heat-conducting inner pipe 7. Figure 6 As shown in the figure, the relatively high temperature cooling medium will heat the gas in the annular air cavity 8, causing the gas in the annular air cavity 8 to expand and the internal air pressure of the annular air cavity 8 to increase. Since the annular air cavity 8 is connected to the lifting cylinder 627, when the air pressure in the annular air cavity 8 increases, the lifting cylinder 627 will extend further to push the regulating piston 625 upward. The higher the temperature of the cooling medium, the higher the internal air pressure of the annular air cavity 8, and the greater the upward distance of the regulating piston 625.
[0042] like Figure 8 As shown in , the regulating piston 625 moves upward so that the hydraulic oil in the regulating cavity 624 enters the hydraulic cylindrical cavity 619 through the interactive flow channel 626, pushing the hydraulic piston 620 and the movable slider 615 to move, so that the driving pin 616 moves away from the center of the dynamic turntable 613. At this time, when the dynamic turntable 613 rotates at a constant speed, the reciprocating stroke of the magnetic ring fixing seat 611 and the external magnetic ring 610 is increased during the cycle of one rotation of the dynamic turntable 613, thereby improving the pumping flow rate and increasing the heat exchange efficiency. The automatic adjustment of the pumping flow rate is achieved through mechanical connection without relying on the speed change of the dynamic turntable 613, so that the dynamic turntable 613 and the pulley 623 can be directly connected to the input power of the generator, without the need to set up a separate motor for control, thereby optimizing the mechanical structure.
[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
