Description
Technical field
The utility model relates to generator radiating structures, more particularly, to a kind of external water cooling generator's cover.
Background technique
With constantly increasing the miniaturization of internal combustion generating set, light-weighted demand, middle-size and small-size water-cooled generator is sealed
Using also more and more.Because there are eddy-current loss, iron loss, magnetic hystersis loss, stray loss etc., generators in the generator course of work
The heat of certain power can be generated.
Since generator insulating component just has insulation performance at a certain temperature, and the length of service of design can be maintained,
And bearing when generator work also has temperature limiting, so these heats needs that generator generates when working transfer out in time
Go, with ensure generator work permission at a temperature of.Middle-size and small-size water-cooled generator is sealed at present generally uses stator water-cooling
Mode, but since rotor is rotary part, water channel arrangement and sealing are more difficult.There are also by the way of conducting and radiating naturally
Hot transmitting is carried out, but since rotor coil is centralized winding, radiating condition is more unfavorable, caused by often there is heat aggregation
A series of problems, such as generator bearing is burnt, and failure of insulation or aging accelerate.It lays the course if covered in generator end, a side
Face increases the difficulty of processing of end cap, is in addition also inconvenient for safeguarding, while having an effect on appearance.
Summary of the invention
The purpose of this utility model is to provide a kind of external water cooling generator's covers, to solve the generator course of work
The heat dissipation problem of middle rotor.
To achieve the above object, the utility model can take following technical proposals:
External water cooling generator's cover described in the utility model, including the end cover body with installation inner hole, the end
It is provided with cooling water channel in lid, is fixed with water route attachment base in outer cover of the end cover body, is mounted on the water route connection
Inlet and outlet water nozzle on seat is connected with the entery and delivery port of the cooling water channel；The equalization setting on the end cover body lateral wall
There is the engaging lug with connecting hole.
The installation inner hole outer side edges are provided with generator bearing positive stop lug boss.
It is simple that the utility model has the advantage of structures, processing, easy for installation, compact, the cooling to motor bearings
Effect is good, and bearing temperature rise reduces maintenance cost within the temperature range of permission when can guarantee motor work.

Specific embodiment
As shown in Figure 1-3, external water cooling generator's cover described in the utility model, including with installation inner hole 1
End cover body 2 is provided with cooling water channel 3 in end cover body 2, is fixed with water route attachment base 5 on the outer cover 4 of end cover body, is mounted on water
Inlet and outlet water nozzle on road attachment base 5 is connected with the entery and delivery port of cooling water channel 3；The equalization setting on end cover body lateral wall
There is the engaging lug 6 with connecting hole；Installation 1 outer side edges of inner hole are provided with generator bearing positive stop lug boss 7.
As shown in Figure 4,5, in use, end cover body 2 is mounted on generator main side lid 101 by engaging lug 6, in installation
The positive stop lug boss 7 of 1 outer side edges of hole can reliably position generator bearing 102.It, be in generator when end cover body 2 is installed
Heat conductive silica gel is applied between main side lid 101 and the contact surface of end cover body 2, to ensure that the two has good thermal conductivity and contact area；
Inlet and outlet water nozzle on water route attachment base 5 is connected to by pipeline with the cooling major loop of generator, cooling medium passes through end cover body 2
On cooling water channel 3 be connected in parallel in the major loop of water-cooled generator cooling system, the heat for being covered generator end by major loop
Amount passes, and such cooling device is easy for installation, has the characteristics of small in size, good cooling results.
Through testing, before not installing the utility model, generator runs 2 hours rear bearing temperature up to 140 DEG C, and bearing leaks
Oily phenomenon, measurement generator amature temperature rise reach 140K(electric-resistivity method)；After the utility model end cap is installed outside generator bearing,
Generator amature temperature rise is 89K, meets the requirement that H class B insulation is no more than 125K, bearing portion temperature is at 86 DEG C hereinafter, meeting 95
DEG C or less operating condition, it is ensured that generator bearing work within the temperature range of permission.
