Heat；In terms of process control, program control system is taken, reasonable heat exchange mode is chosen according to temperature, realizes heat exchange；Safeguard protection
Alarm is arranged in aspect inside magneto, alarms in temperature anomaly.
Beneficial effects of the present invention:
Device for monitoring temperature and alarm system are added inside magneto, add runner on stator, stator outer surface and fixed
There is cold medium by improving original heat exchanger exchange fin structure, enhancing its heat exchange to reach heat exchange purpose in son and rotor clearance
Ability exchanges heat to magneto using a kind of quick heat-exchange system of magneto combined type, it is ensured that magneto work peace
Complete reliable, since today's society develops rapidly, speed needed for industrial production is accelerated, and magneto is as the most normal in industrial production
The equipment seen, be subjected to load is increasing, and problems of excessive heat is also just more prominent, and magneto efficiency needs to improve, and is working as
In modern production work, big load condition becomes more common, and original heat exchange mode is no longer satisfied today's society needs, need to adopt
With reasonable heat-exchange method, guarantee heat exchange efficiency, prevents due to safety accident caused by overheating.A kind of magneto combined type is fast
Quick change hot systems solve original mode limitation greatly and the defects of low efficiency, realization are applied in combination using multiple heat exchange modes
Overall heat exchange solves the problems, such as that original mode has heat exchange deficiency, avoids overheating during the work time, influence equipment work
Make the service life, there are security risks, can significantly shorten the period using a kind of quick heat-exchange system of magneto combined type, mention
