The expansion tube type water-cooling base for the motor has the advantages that: the water channel sealing rings with the sealing channels are employed, a tightly-sealed structure is formed after expanding connection of the end of the heat exchange tube and the sealing channels, and used for preventing leakage; and by adoption of the heat exchange tube with inner ribs, internal radiating area is increased, water-side heat exchange is greatly strengthened, and the temperature rising of a rotor of a generator is reduced.
Description
Technical field
The present invention relates to motor water cooling base, be applicable to the cooling of medium-and-large-sized generator.
Background technology
Along with the continuous development of high-power wind-driven generator, owing to receive the restriction of confined space size in the cabin, the cooling of water jacket support is also further used.Because the cooling of water jacket support directly comes cooled electric generator through heat conduction with forcing convective heat transfer liquid, so the generator temperature rise can be controlled preferably.
Present water jacket support runs into following problem in application: (1) is owing to can relate to the welding between the different materials in the water jacket support usually; And water jacket support generally requires water pressure resistance higher (between 1 ~ 2Mpa), and this is with regard to the seal leakage problem that can cause water channel usually and cause the generator over-heated fault; (2) because water jacket support has received the restriction of size aspect, though the heat exchange of water side owing to be that forced convertion has obtained the heat exchange reinforcement, the heat exchange of gas side still is subject to convection transfer rate and heat exchange area; For above-mentioned reasons, though general stator temperature is lower, the air-cooled air side radiating effect that circulates in rotor relies on is all undesirable.
Summary of the invention
The object of the present invention is to provide a kind of expand tube type motor water cooling base, the inner rib plate heat exchanger tube that has adopted the expand tube formula solves leakage and the not good problem of air side radiating effect in the present water jacket support to realize high efficient heat exchanging.
Technical scheme of the present invention is following:
A kind of expand tube type motor water cooling base comprises outer cylinder body and inner barrel, and the length at said outer cylinder body two ends exceeds the length of inner barrel; The two ends of said outer cylinder body are connected with end ring, and its surface is provided with water inlet and delivery port, and its below is connected with footing; The two ends of said inner barrel are connected with outer cylinder body through the water channel sealing ring; Form the water channel framework by inner barrel, outer cylinder body and water channel sealing ring; Connect multiple tracks water channel muscle on the water channel sealing ring in the water channel framework and form circuitous water channel; Between adjacent two water channel muscle, heat exchanger tube is set, the two ends of said heat exchanger tube are fixed on the water channel sealing ring, and said water channel sealing ring is provided with pore; Offer sealed groove on the circumference of pore; After said heat exchanger tube passed the pore of water channel sealing ring, expanded joint was in the pore of water channel sealing ring, and the tubing of said heat exchanger tube gets into and forms sealing in the sealed groove.
Its further technical scheme is: have fin on the inner tubal wall of said heat exchanger tube.
Useful technique effect of the present invention is:
(1) the present invention adopts the water channel sealing ring that has sealed groove, through forming fine and close hermetically-sealed construction behind the expanded joint of heat exchanger tube end; (2) the present invention adopts the heat exchanger tube that has inner rib plate, strengthens the heat exchange of gas side greatly, reduces the generator amature temperature rise.

Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in Figure 2, the present invention mainly comprises outer cylinder body 6 and inner barrel 7, and wherein the length at outer cylinder body 6 two ends exceeds the length of inner barrel 7.The two ends of outer cylinder body 6 are connected with end ring 1, and its surface is provided with water inlet 3 and delivery port 4, and its below is connected with footing 8.The two ends of inner barrel 7 are connected with outer cylinder body 6 through water channel sealing ring 2, form the water channel framework by the water channel sealing ring 2 at inner barrel 7, outer cylinder body 6 and two ends.As shown in Figure 2, be connected with multiple tracks water channel muscle 9 on the water channel sealing ring 2 in the water channel framework and form circuitous water channel.Between adjacent two water channel muscle 9, be provided with heat exchanger tube 5, the two ends of heat exchanger tube 5 are fixed on the water channel sealing ring 2.
Cooling water is after water inlet 3 entering of support, behind circuitous water channel muscle 9, with taking away after process inner barrel 7 heat conduction of generator unit stator heat and the water forced convertion.Simultaneously, the generator amature heat is taken away gas side heat through heat exchanger tube 5 through interior circulation wind path through the outer forced-convection heat transfer of the convection current of tube wall gas side, tube wall heat conduction and pipe.
Since the higher materials of conductive coefficient such as heat exchanger tube 5 general employing copper, aluminium, and the water channel sealing ring 2 general ordinary carbon steels that adopt adopt and weld then poor-performing, therefore select for use new connected mode alternative.As shown in Figure 3, the present invention adopts a kind of water channel sealing ring 2 that has sealed groove 10 pores, pass the pore of water channel sealing ring 2 at heat exchanger tube 5 after, adopt tube expander with the pipe end expanded joint of heat exchanger tube 5 in the pore of water channel sealing ring 2.Because heat exchanger tube 5 adopts materials such as copper, aluminium, material is softer, therefore receives in the laggard sealed groove 10 of going into water channel sealing ring 2 of expand tube extruding and forms fine and close hermetically-sealed constructions, thereby solved the water channel leakage problem that causes because of different tubing welding failures in the water channel.
Because the generator amature caloric requirement is taken away gas side heat through heat exchanger tube 5 through interior circulation wind path through the outer forced-convection heat transfer of the convection current of tube wall gas side, tube wall heat conduction and pipe.In order to solve the problem that the heat radiation of gas side receives water jacket support size restrictions, the present invention uses a kind of radiating tube 5 with inner rib plate, and is as shown in Figure 4.Have a plurality of fins on the inner tubal wall of radiating tube 5, can be made through the mould drawing of making this style.This structure has increased the area of dissipation of radiating tube 5 inside greatly, thereby has strengthened the heat exchange of gas side greatly, has reduced the temperature rise of generator amature.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
