Abstract
The invention discloses a water channel cooling device of a high-power doubly-fed wind driven generator. The water channel cooling device comprises an inner barrel and an outer barrel, wherein the two barrels are in interference fit with each other; joints at two ends of the two barrels are welded; a water inlet and a water outlet are formed in the outer barrel, and water flow can enter the inner barrel through the water inlet; the inner barrel comprises end barrels and a middle barrel; the end barrels are positioned at two ends of the middle barrel; waterproof ribs and a plurality of water channel ribs are arranged on the outer surface of the middle barrel; the water inlet and the water outlet are correspondingly formed in two sides of the waterproof ribs; a water channel is formed between every two adjacent water channel ribs; two end parts of the waterproof ribs are connected with the two end barrels; only one end of each water channel rib is connected with one of the end barrels, and a disconnection position between each water channel rib and the other end barrel is a reversing region for the water flow; the ends of every two adjacent water channel ribs, which are connected with the end barrels, are opposite. According to the water channel cooling device of the high-power doubly-fed wind driven generator, the spiral structures of the conventional water channels are optimized into horizontally welded structures, so that the processing amount is small, and raw materials are saved; the processing period is short, the working efficiency is high; batch production can be realized.
Description
Technical field:
Patent of the present invention relates to a kind of cooling device, relates in particular to a kind of double-fed wind power generator water passage cooling device.
Background technology:
The cooling processing of high-power double-fed wind driven generator, general air cooling equipment and the water cooling plant of adopting, water cooling plant generally be take inner core as spiral channel, and inner core, urceolus connect in interference mode and two ends seam crossing firm welding, inner/outer tube is combined effectively, become one.In this kind of spiral channel cooling procedure, cooling effect is better, significantly not enough but this traditional spiral channel version exists: processing capacity is large, waste of raw materials; Lathe tools loss is large, and processing cost is high; Process-cycle is long, and inefficiency is difficult to realize batch production.
Summary of the invention:
For addressing the above problem, the invention provides a kind of double-fed wind power generator water passage cooling device, change the helical structure of existing water passage cooling device, making water channel is welding water channel, can cut down the consumption of raw materials and production cost, and formation batch production, meanwhile, the current of welding water channel are that horizontal cross flows, and the current of spiral channel flow along water channel is spiral, compare with spiral channel, the cooling effect of welding water channel further improves.
The present invention is achieved through the following technical solutions:
A high-power double-fed wind driven generator water passage cooling device, comprises inner core and urceolus, and two connect in interference mode, and the seam crossing at its two ends is soldered;
On described urceolus, have water inlet and delivery port, current enter inner core from water inlet;
Described inner core comprises end cylinder and intermediate cylinder, and end cylinder is positioned at the two ends of intermediate cylinder, and the outer surface of intermediate cylinder arranges confining tendon and many water channel muscle, and described water inlet and delivery port are corresponding to the both sides of confining tendon; Between adjacent two water channel muscle, form water channel, two ends of described confining tendon join with two end cylinders respectively; Every water channel muscle only has one end and end cylinder to join, the commutating zone that the breaking part of water channel muscle and end cylinder is current, adjacent two water channel muscle are different with the link of end cylinder, current flow along water channel, after ingoing stream commutating zone, change the direction of a stream of water, current after break-in flow into secondary water channel, until current are blocked by confining tendon, by delivery port, flow out.
Beneficial effect:
The helical structure of water channel is optimized for to horizontal welding connecting structure, and processing capacity is little, saves raw material; Process-cycle is short, and operating efficiency is high, can realize batch production; Reduced to a certain extent motor manufacturing cost; The change of this structure, has increased the spacing of water channel muscle, has solved the susceptible to plugging difficult problem of original water channel; Compared to helical flow, bottom horizontal flow sheet radiating effect is better, and the temperature rise of motor is effectively lowered.
