Description
Technical field
Blower fan technical field is the utility model is related to, more particularly, to a kind of antifreeze air cooler of air cooling turbo-generator.
Background technology
In the season of cold, outdoor environment temperature is relatively low, does not start air cooling blower fan, is only entered with the air inlet through air cooling blower fan
Enter the cold wind flowed naturally of air duct, it is possible to which the exhaust steam in the tube bank of air cooling condenser radiating fin is condensed out.Such as
The temperature of fruit environment is further reduced, and radiating fin can be caused into the cold wind that air duct flows naturally by the air inlet of air cooling blower fan
Piece tube bank in exhaust steam and condensed water frosting and icing, air cooling condenser radiating fin tube bank in exhaust steam and condensed water knot
Frost and icing, the flowing of condensate normal circulation is severely impacted or destroyed, unit normal operation is not only influenceed, can also cause to hold high
Expensive air cooling condenser bursting by freezing damage.Unit load change cause air inlet cooling condenser steam amount it is very few or
When person's variation of ambient temperature scope is larger, the exhaust steam state in the tube bank of air cooling condenser radiating fin is more big changes.
Nighttime ambient temperature is too low or when steam amount is very few, and the above-mentioned cold air flowed naturally will also result in the exhaust steam in cooling condenser
With condensed water frosting and icing.It is too low in above-mentioned cold season or nighttime ambient temperature and when steam amount is very few, it is necessary to
The method that air cooling condenser cold wind is blown in reduction nature flowing avoids the exhaust steam in air cooling condenser and condensed water
Frosting and icing.In the prior art, air cooling condenser radiating fin tube bank lower section air cooling blower fan air inlet be it is unlimited,
Too low in the season of cold or nighttime ambient temperature and when steam amount is very few, this air cooling blower fan is not avoided that through air cooling blower fan
The cold wind that flows naturally of air inlet cause radiating fin restrain in condensed water frosting and icing.
