Description

Overbottom pressure cogeneration machine path formula cooling device

Affiliated technical field:

Overbottom pressure cogeneration machine path formula cooling device; What relate to is to change generator cold air chamber structural design; The heat that produces in the generator energy transfer process is directly discharged by the path, reach the structural design that the control generator-temperature detection raises through generator cold air chamber air temperature modification.

Background technology:

The cooling of known overbottom pressure cogeneration machine adopts the water in the empty cooler in the cold air chamber to carry out the structural design that cold and hot air exchange is controlled temperature, when generator in conversion process of energy; Except most of mechanical energy changes into the electric energy, electric energy and the copper loss of generator own of few part, the energy of the many losses of iron loss also to be arranged, outside under the drive of energy overbottom pressure waste heat; All being converted into heat energy in the mechanical energy converting electrical energy process discharges; Get into air cooler through the heat extraction air channel and by the current in the empty cooler heat energy is being taken away, air cooler uses for a long time, and tube wall can corrosion fracture seepage and the incrustation scale water that stops up; Cause heat exchange property to reduce; Generator sucks the too high meeting of wind-warm syndrome and makes stator coil, the corresponding rising of iron core temperature, makes insulation that embrittlement take place, and forfeiture machinery is powerful; The generator life-span is shortened greatly; Can cause when serious that generator insulating damages to puncture causes the accident, and generator sucks wind-warm syndrome and crosses the low stator coil surface globule that condenses that can cause and reduce its insulating capacity, makes generator damage the service life that has shortened generator.

Traditional overbottom pressure cogeneration machine solves generator in conversion process of energy, and the method that temperature raises is to adopt construction air cooler chamber that air cooler is installed again; Through the air cooler water flow inside heat energy that produces in the generator rotation is taken away; Again the air in the air cooler chamber is sucked generator inside by generator amature both sides fan the whole generator temperature is descended, reach the cooling purpose, traditional overbottom pressure cogeneration machine cooling structure is designed with obvious defects; In case taking place, aerial cooler tube wall cracking current will be ejected into electricity generator stator coil and generator outlet bus; Cause the generator scaling loss, and the high time of the big labour intensity of air cooler maintenance workload is long, air cooler is through the current that flow heat to be taken away simultaneously; Design defect obviously causes water resource waste; Do not embody the substantive characteristics of overbottom pressure afterheat energy-saving environment-friendly type generator, the design of generator cooling structure obviously falls behind, and has restricted the development of overbottom pressure afterheat energy-saving generator.

The utility model content:

In order to solve overbottom pressure cogeneration machine tradition cooling structural design defective; Overbottom pressure cogeneration machine cold wind indoor design is the heat extraction path independently, and the heat that produces in the generator rotary course is directly discharged outside the cold air chamber through the path, and generator heat extraction path is designed with two automatic temperature control switch heat extraction air doors; Two automatic temperature-controlled heat extraction air doors suck the wind-warm syndrome requirement according to the generating electricity in winter machine; Automatic switch is regulated and is improved cold air chamber's temperature, and four automatic temperature control switch air doors are equipped with in generator cold air chamber, reduces cold air chamber's temperature according to the air circulation that summer, generator sucked in the wind-warm syndrome requirement automatic switch reinforcement cold air chamber; Keep temperature standard between 3 ℃ to 35 ℃ of the generator cold air chamber ambient temperatures; Heat extraction path and cold air chamber's acting in conjunction descend the whole generator temperature, have realized temperature heat exchange function in the generator rotary course.Its objective is; The one, avoid generator to utilize the water in the air cooler to carry out the Cooling Design defective, practiced thrift water resources, reduced air cooler equipment funds input simultaneously; Regular maintenance expense and labour cost have been eliminated; The 2nd, independently heat extraction path and the air circulation design control whole generator temperature rise of generator cold air chamber descend, and generator cooling technology scope has been widened in the design advantage energy-conserving and environment-protective.

Overbottom pressure cogeneration machine path formula cooling device solves the technical scheme that its technical problem adopted:

In overbottom pressure cogeneration machine cold wind indoor design heat extraction path independently; The heat that produces in the generator rotary course is directly discharged outside the cold air chamber through the heat extraction path, solve generator and through the current in the air cooler heat energy is taken away the problem of cooling, its structure one is that generator heat extraction path is designed with two automatic temperature control switch heat extraction air doors; Two automatic heat extraction air doors suck the wind-warm syndrome requirement according to the generating electricity in winter machine; Automatic switch is regulated and is improved cold air chamber's temperature, and the 2nd, four automatic temperature control switch air doors are equipped with in generator cold air chamber, reduce cold air chamber's temperature according to the air circulation that summer, generator sucked in the wind-warm syndrome requirement automatic switch increase cold air chamber; Heat extraction path and cold air chamber's acting in conjunction; The whole generator temperature is descended, realized temperature control in the generator rotary course, reached the purpose that reduces generator-temperature detection.

Beneficial effect:

The beneficial effect of overbottom pressure cogeneration machine path formula cooling device; Remedy conventional electric generators and utilized the design defect of the cold and hot air exchange of air cooler, solved the water that utilizes in the air cooler and carried out the generator cooling, caused the problem of water resource waste; Widened the technical scope of generator Cooling Design; The cooling structure simplicity of design of overbottom pressure cogeneration machine path formula cooling device, low, the easy to maintenance whole generator good cooling results of construction cost is through the test proof; Generator cold air chamber increases air circulation cold wind indoor temperature summer and can be controlled at below 35 ℃; Winter, the cold wind indoor temperature can remain on more than 3 ℃ under two the automatic temperature control switch heat extractions in generator heat extraction path air door is regulated; Meet generator and suck wind-warm syndrome greater than 3 ℃ of standards less than 35 ℃; The formula cooling device energy-conserving and environment-protective of generator path, practicality, generalization are strong.
