Abstract
The utility model discloses a kind of sealing water-cooling structure disc type electric machine, comprise casing, front end housing, rear end cap, rotating shaft, front winding and rear winding, in front end housing, be provided with spiral the first water channel, the first water channel port is water inlet, the first water channel end communicates with straight water channel in machine, in rear end cap, be provided with spiral the second water channel, the second water channel end communicates with straight water channel in machine, and the second water channel port is delivery port.This disc type electric machine is by enclosed construction, undertaken coolingly by water, effectively reduces the each part temperatures of motor internal, improved power of motor density, avoids local overheating, ensures motor safety operation, increases the service life.
Description
Technical field
The utility model relates to a kind of disc type electric machine, relates in particular to a kind of water-cooled disc type electric machine of enclosed construction.
Background technology
Disc type electric machine volume is little, lightweight, efficiency is high, applies very wide.For the radial structure disc type electric machine of high power density, its type of cooling mainly adopts casing water-cooled.This device is generally made up of casing inner sleeve, casing overcoat, forms interlayer between the two, and electric machine stator iron contacts with casing inner sleeve, and heat in motor is transmitted to casing inner sleeve, then by the cooling water in interlayer, motor internal heat is taken away.This water cooling plant has reduced motor surface temperature rise to a certain extent, but poor to motor internal cooling-down effect, because motor internal air flow property is poor, in motor, the heat of each pyrotoxin can not effectively shed, easily make heat accumulation in motor internal somewhere, cause local overheating, thereby affect safe operation and the useful life of motor.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of enclosed construction, carries out cooling disc type electric machine by water, can effectively reduce the each part temperatures of motor internal, improve power of motor density, avoid local overheating, ensure that motor safety moves and improves useful life.
For achieving the above object, the technical solution of the utility model is: a kind of sealing water-cooling structure disc type electric machine, comprise casing, front end housing, rear end cap, rotating shaft, front winding and rear winding, in front end housing, be provided with spiral the first water channel, the first water channel port is water inlet, and the first water channel end communicates with straight water channel in machine, is provided with spiral the second water channel in rear end cap, the second water channel end communicates with straight water channel in machine, and the second water channel port is delivery port.
As the further setting of such scheme, the first water channel is contrary with the second water channel rotation direction.
As the further setting of such scheme, the first water channel, the second water channel equate with straight water channel diameter in machine respectively.
The beneficial effects of the utility model are:
1, owing to adopting water-cooling pattern, extraneous environmental aspect is less on cooling effect impact.
2, cooling water, by straight water channel, the second water channel in the first water channel, machine, does not take space in machine, in the situation that not affecting disc type electric machine work, increased to greatest extent area of dissipation, and radiating rate is fast, and power density is high.
3, the main heat generating components of disc type electric machine is winding, and forward and backward end cap water channel is helical form, in machine, straight water channel is straight shape, therefore cooling water is longer in the forward and backward end cap water channel time of staying, in machine, the straight water channel time of staying is shorter, the temperature difference of cooling water and winding is enough large, long in the front and back ends cover time of staying, can fully carry out heat exchange.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is front end housing structural representation;
Fig. 3 is rear end cover structure schematic diagram;
Fig. 4 is straight water channel schematic perspective view in machine.
In figure: straight water channel 7, delivery port 8 in casing 1, front end housing 21, rear end cap 22, rotating shaft 3, front winding 41, rear winding 42, the first water channel 51, the second water channel 52, water inlet 6, machine.
Embodiment
Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.
Embodiment:
As shown in Figure 1, a kind of sealing water-cooling structure disc type electric machine, comprise casing 1, front end housing 21, rear end cap 22, rotating shaft 3, front winding 41 and rear winding 42, in front end housing 21, be provided with spiral the first water channel 51, the first water channel 51 ports are that water inlet 6, the first water channel 51 ends communicate with straight water channel 7 in machine, are provided with spiral the second water channel 52 in rear end cap 22, the second water channel 52 ends communicate with straight water channel 7 in machine, and the second water channel 52 ports are delivery port 8.
The first water channel 51 is contrary with the second water channel 52 rotation directions, to improve cooling effectiveness.
The first water channel 51, the second water channel 52 equate with straight water channel 7 diameter in machine respectively.
Operation principle of the present utility model is: when cooling, pass into cooling water by water inlet 6, the front winding 41 that cooling water is driving side through spiral helicine the first water channel 51 is lowered the temperature; Leave after front end housing 21, cooling water enters straight water channel 7 in machine, carries out heat exchange with motor internal air; Subsequently, cooling water enters rear end cap 22, and then lowers the temperature for the rear winding 42 of non-drive side, is finally discharged by delivery port 8.
