Description

A kind of fluid-cooled electrical machine
Technical field
The invention belongs to the motor liquid cooling field, be specifically related to a kind of cooling fluid-cooled electrical machine of stator winding end seal closure that adopts.
Background technology:
Can produce a large amount of heat, particularly heavy-duty motor during machine operation, the very large needs of caloric value are in time discharged.Motor can be divided into air cooling and the large class of liquid cooling two according to the difference of coolant, and air cooling technology is because the little cooling effect of specific heat of gas is not good, if it is high to adopt hydrogen_cooling explosive-proof grade and additional cooling device etc. to require, is difficult on middle and small motor universal.In motor, liquid cooling can make heater contact with conduction oil, greatly reduces thermal resistance chain and thermal resistance value between winding and fluid, reduces the temperature rise of motor internal.Existing oily cyclic internal cooling motor mainly is divided into three kinds of forms: whole oil-immersed type (being full of cold oil in casing), oil injection type (carrying out cooling thereby utilize nozzle to form mist of oil to the oil spout of rotor blade), mistake oily formula (the motor stator outer surface is crossed oil cooling but).There is following defective in existing oily cyclic internal cooling motor: (1) because the density of cold oil is larger, kinematic viscosity coefficient is high, because rotor integral body is immersed in oil, causes when rotated larger frictional dissipation, and is particularly more obvious when high speed.(2) oil injection type cooling means, the oil pressure that needs due to oil atomizer is higher so oil pump power is large and the loss of blade when stirring at a high speed is also larger.(3) cross oily formula and mainly the stator outer wall was carried out oil cooling but, a small amount of oil droplet is cooling to rotor to the rotor blade, can't be directly directly cooling to the winding part of caloric value maximum, owing to existing thermal resistance so heat-conducting effect also can be limited between winding and stator outer wall, and motor casing is driven oil groove and is caused production cost higher.
Summary of the invention:
The objective of the invention is to overcome deficiency of the prior art, circulation fluid cool electric machine technical scheme in adopting solves existing inner-cooled machine cooling effect poor, and loss is large, and the high in cost of production problem provides the fluid-cooled electrical machine that a kind of cost is low, loss is little, cooling effect is good structure.
Its technical scheme is:
Comprise electric machine casing, stator core, stator winding coil, rotor, rotating shaft, front end housing, rear end cap, pump, radiator, woven hose, reservoir, bearing; The both sides of stator core respectively have a seal closure, be respectively the first seal closure and the second seal closure, the first seal closure and the second seal closure are loop configuration, the outer shroud end of annular is fixed on the inwall of electric machine casing, the interior ring end of annular is fixed on the side of stator core, and the inwall of the first seal closure, electric machine casing, the side of stator core form confined space jointly; The inwall of the second seal closure, electric machine casing, stator core side forms confined space jointly; The side that the both side ends of stator winding coil is placed in respectively two seal closures and electric machine casing, stator core forms two confined spaces; Two seal closures by stator core external annulus or the electric machine casing inwall on the some grooves or the woven hose that have be connected; The first seal closure, the second seal closure, electric machine casing, woven hose, radiator, pump, reservoir form the liquid communication loop, have some intercommunicating pores on electric machine casing, the first seal closure, the second seal closure are connected with reservoir with woven hose by intercommunicating pore, thereby are communicated in this liquid communication loop.
Described fluid-cooled electrical machine adopt water or cooling oil as cooling fluid.
The cross sectional shape of the loop configuration of described the first seal closure and the second seal closure is L-type or arc.
Two airtight sealing covers by stator core external annulus or the electric machine casing inwall on have some grooves or woven hose when being connected, groove mode of communicating and woven hose mode of communicating can and be deposited, and can use simultaneously groove and woven hose to be communicated with; And when only using branch that woven hose forms to be communicated with, it is corresponding with it that the intercommunicating pore that each seal closure is connected with the branch of woven hose need to also have at the other end of electric machine casing an intercommunicating pore.
When two airtight sealing covers were communicated with by woven hose, woven hose was divided into some in the outside of electric machine casing, formed and being communicated with of two seal closures by some intercommunicating pores.
Described the first seal closure has overfolw hole or the second seal closure has overfolw hole or two seal closures all have overfolw hole, overfolw hole be positioned at its residing seal closure top with and the bearing top of place one side, the electric machine casing bottom has return port, overfolw hole is positioned at the bearing below of its place one side, and return port is connected with reservoir.
The first seal closure or the second seal closure have overfolw hole, and the bearing of its place one side is open bearing, and the cooling fluid in fluid-cooled electrical machine is overflowed and drenched to bearing by overfolw hole, is back in reservoir finally by return port.
The top perforate of described electric machine casing also is equipped with respirator, and respirator is connected with two seal closures and the formed confined space of electric machine casing.
The first seal closure and the second seal closure are fixed on the side of the inwall of electric machine casing and stator core by welding or the solid mode of glue.
Than traditional fluid-cooled electrical machine, the present invention has significant advantage and beneficial effect, is embodied as:
1. this fluid-cooled electrical machine adopts Stator End Winding sealing immersion liquid heat exchange, thereby winding directly contacts with cooling fluid and reduced the thermal resistance chain, has reduced thermal resistance value, so cooling effect is better.
